Govind Ballabh Pant University of Agriculture and Technology, Pantnagar
After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960.
The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

ThesisItem Open Access Studies on mineral profile in feeds, soil and animals in Haridwar district of Uttaranchal(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-01) Tiwary, Manoj Kumar; Tiwari, D.P.A survey was conducted in four villages, two each from Roorkee and Laksar Tehsils, of Haridwar district of Uttaranchal in order to find out the existing livestock practices, macro and micro nutrients profile in soil, feeds and fodder and animals and also to establish the correlations among soil, plant and animals. Fifteen farmers under three major categories on land holding basis i.e. landless (0 acre), small (2-5 acres) and large (>5 acres) from each village were selected, from where the above informations and samples of soil, feeds, fodder and blood of animals of different physiological status were collected. The collected feed, soil, water and blood samples were subjected for macro and micro nutrient analysis. The CP (23.41 %) and total ash (16.91 %) content were highest in cowpea green whereas, lowest in wheat straw (3.33 % and 7.70 %), in Roorkee Tehsil. While in concentrate, CP content was highest in soybean cake. Animals of the target area showed negative balances in DM, CP and ME intakes. Aneostrus problems were higher in the villages of Roorkee Tehsil as compared to Laksar Tehsil whereas, incidence of repeat breeding in cattle and buffaloes were higher in villages of Laksar Tehsil than Roorkee Tehsil. Only soil of Roorkee Tehsil was found deficient in calcium while rest minerals were found above their respective critical levels. In concentrate ingredients, all minerals except copper such as calcium, phosphorus, magnesium, zinc, iron, cobalt, manganese and selenium were above their respective critical levels with corresponding values as 0.38 ± 0.01, 0.36 ± 0.02, 0.11 ± 0.01 per cent, 53.77 ± 1.78, 279.95 ± 6.96, 0.31 ± 0.04, 65.93 ± 4.34 and 0.15 ± 0.02 ppm, respectively, whereas, copper was found 7.74 ± 0.51 ppm, below its critical level. Likewise, in roughage, minerals such as calcium, magnesium, zinc, iron, cobalt, manganese and selenium were above the critical levels with corresponding values as 0.36 ± 0.03, 0.10 ± 0.01 per cent, 53.50 ± 6.47, 297.78 ± 21.73, 0.49 ± 0.12, 47.01 ± 8.01 and 0.18 ± 0.02 ppm, respectively, whereas, phosphorus and copper were 0.20 ± 0.03 per cent and 5.06 ± 0.75 ppm, respectively, below their respective critical level. The blood serum mineral concentration except for copper and phosphorus i.e. calcium, magnesium, zinc, iron and manganese (10.43 ± 0.22 mg/dl, 1.65 ± 0.14 mg/dl, 1.54 ± 0.11 ppm, 1.97 ± 0.19 ppm and 0.54 ± 0.02 ppm) were found to be above their respective critical levels and were not deficient. The serum phosphorus (3.79 ± 0.21 mg/dl) and copper (0.46 ± 0.07 ppm) were deficient with their values falling below their respective critical levels. Soil-plant-animal correlations for different minerals did not show clear cut picture regarding their accumulation in plants and utilization by the animals. Research findings revealed for the supplementation of phosphorus, copper as well as magnesium in the selected areas of Haridwar.ThesisItem Open Access Studies on mineral profile in feed, soil and animals in Pithoragarh district of Uttaranchal(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-05) Shukla, Saraswati; Tiwari, D.P.A survey was conducted in four villages, two each from Pithoragarh and Gangolihat Tehsils, of Pithoragarh district of Uttaranchal in order to find out the existing livestock feeding practices, macro and micro nutrients profile in soil, feeds and fodder and animals and also to establish the correlations among soil, plant and animals. Fifteen farmers under four major categories on land holding basis i.e landless (0 acre), marginal (<1 acres), small (1-2 acres) and medium (>2 acres) were selected to collect samples of soil, feeds and blood of animals of different physiological status. The collected feed, soil, water and blood samples were subjected for macro and micro nutrient analysis. The CP (14.50%) content were highest in shahtut leaves whereas, lowest in paddy straw (3.35 %). While in concentrate, CP content was highest in commercial pellet. Animals of the target area showed negative balances in DM, DCP and TDN intakes. Aneostrus, repeat breeding and other reproductive problems were higher in the villages of Gangolihat Tehsil as compared to Pithoragarh Tehsil. The soil of all the villages was deficient in calcium while other minerals were above to their corresponding critical levels. In concentrates all minerals except calcium and copper such as phosphorus, magnesium, zinc, iron, cobalt, and manganese were found above the critical levels, whereas calcium (0.156 ±0.001 per cent) and copper (7.10 ± 0.17 ppm) were below the critical level. Likewise, in roughage calcium and copper were 0.175 ± 0.006 per cent and 6.78 ± 0.17 ppm, respectively which fall below critical level while other minerals such as phosphorus, magnesium, zinc, iron, cobalt and manganese were above the critical levels. The blood serum mineral concentration except calcium, copper and manganese i.e. phosphorus, magnesium, zinc and iron were above the critical levels and not found deficient. The serum calcium (4.33 ± 0.12 mg/dl), copper (0.34 ± 0.07 ppm) and manganese (0.18 ± 0.09 ppm) concentration were deficient and were below critical levels. Soil-plant-animal correlations for different minerals did not show clear-cut picture regarding their accumulation in plants and utilization by the animals. Research findings revealed that the supplementation of calcium, copper and manganese in the ration of animals is inevitable in these two Tehsils of district Pithoragarh.ThesisItem Open Access Effect of feeding diet containing graded levels of pea (Pisum sativum L.) pods residue powder by replacing rice polish on performance of broiler chickens(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-08) Narayana, Krishan Prem; Mondal, B.C.A feeding trial was conducted to discern the effect of dietary incorporation of pea (Pisum Sativum L.) pods residue powder by replacing rice polish on growth performance, nutrient utilization, haemato-biochemical parameters, carcass traits, sensory evaluation and economics of broiler chickens. A total of 120, day-old broiler chicks were divided randomly into 4 treatment groups with 3 replicates in each i.e. 10 broiler chicks per replicate. Chicks of T1 (control) were fed basal diet with rice polish as one of the feed ingredients, whereas in treatment groups T2, T3 and T4, basal diet was incorporated with pea pods residue powder at 50, 75 and 100 per cent levels by replacing rice polish, respectively. The feeding trial lasted for 42 days viz., 0-21 days (starter phase) and 21-42 days (finisher phase). Feed intake and body weight changes in broiler chicks were recorded at weekly intervals and a metabolism trial of 3 days collection period was conducted during the 6th week of feeding trial. Blood samples were collected on 42nd day of feeding trial to study haemato-biochemical parameters. Results of feeding trial indicates that during starter phase (0-21 days), the body weight gain of broiler chicks of treatment groups T2 and T4 were significantly (P<0.05) higher than T1 and T3 treatment groups. Performance index was also found higher in T4 treatment group. During 21- 42 days (finisher phase), body weight gain, feed intake, FCR and performance index were statistically similar among the treatment groups. During whole experimental period (0-42 days), incorporation of pea pods residue powder by replacing rice polish in experimental diet showed similar broiler chicken performance in terms of feed intake, body weight gain, FCR and performance index. Nutrient utilization in terms of dry matter, crude protein, crude fat and organic matter did not differ significantly (P>0.05) among different groups. Sensory characteristics viz., juiciness, texture, overall acceptability (P<0.05) and appearance (P<0.01) were significantly higher in T4 treatment group. Carcass traits were similar among the treatment groups. The protein content in breast (P<0.05) and thigh (P<0.01) muscle were higher in pea pods residue powder incorporated groups. No significant (P>0.05) differences were observed in haematological values among different groups and all the values were in normal range. Significantly (P<0.05) lower serum SGPT activity and increase (P<0.05) in serum total protein content were recorded in broiler chickens of treatment groups fed pea pods residue powder in place of rice polish. There was non-significant difference in serum albumin, globulin, glucose, cholesterol and triglycerides levels. Feed cost per kg body weight gain was similar among the treatment groups. It is concluded that incorporation of pea pods residue powder by replacing rice polish in diet of broiler chickens did not affect growth performance, nutrient utilization, haematological contents, carcass weight and feed cost per kg body weight. Thus rice polish could be replaced completely by pea pods residue powder in the diet of broiler chickens.ThesisItem Open Access Effect of dietary incorporation of aniseed (Pimpinella anisum) and ginger (Zingiber officinale) rhizome powder as feed additive on the performance of commercial broiler chickens(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-07) Gupta, Tushar; Tiwari, D.P.A feeding trial was conducted to discern the effect of dietary incorporation of aniseed and ginger rhizome powder on growth performance, nutrient utilization, carcass traits, haemato-biochemical parameters and economics in commercial broiler chickens. A total of 120, day-old broiler chicks were divided randomly into 4 treatment groups with 3 replicates each i.e. 10 broiler chicks per replicate. Chicks of treatment T1 (control) were fed basal diet (starter and finisher diets), whereas in treatment groups T2, T3 and T4, basal starter and finisher diets were incorporated with 1.0 % aniseed powder, 1.0 % ginger rhizome powder and 0.5 % aniseed + 0.5 % ginger rhizome powder), respectively, as feed additive. The feeding trial lasted for 42 days viz., 0-21 days (starter phase) and 21-42 days (finisher phase). A metabolism trial was conducted during the 6th week of feeding trial to know the nutrient utilization. Blood samples were collected on 42nd day of feeding trial to study haemato-biochemical parameters. During the starter phase (0-21 days), maximum weight gain was recorded in broiler chicks of treatment group T3 (827.70g) fed diet incorporated with 1.0 % ginger rhizome powder followed by treatment groups T1 (807.07 g), T2 (787.43 g) and T4 (773.07 g), however, there was no significant difference in body weight gain amongst the different treatment groups. During finisher phase (21- 42 days), the average body weight gain was 1313.50, 1365.32, 1308.20 and 1291.36 g in broiler chicks of treatment groups T1, T2, T3 and T4, respectively and did not differ significantly among different groups. Feed intake, feed conversion ratio and performance index were not significantly different in broiler chicks of various treatment groups. During entire feeding trial period (0-42 days), incorporation of aniseed and ginger rhizome powder in the basal diets non-significantly improved growth performance in terms of body weight gain, feed conversion ratio and performance index. The average cumulative body weight gain was 2120.57, 2152.75, 2135.90 and 2064.43 g in broiler chicks of treatment groups T1, T2, T3 and T4, respectively and did not differ significantly among different groups. There was no significant difference in feed intake and nutrient utilization among different treatment groups of broiler chickens, however, there was improvement in nutrient utilization due to aniseed and ginger rhizome powder incorporation in the diet. Gizzard weight increased significantly due to inclusion of aniseed and ginger rhizome powder, however, there was no significant difference in other carcass traits among the different treatment groups. There was significant (P<0.05) increase in ether extract content of breast muscles due to inclusion of aniseed and ginger rhizome powder in the diet, whereas it was statistically similar in thigh muscles of broiler chicks. There was significant increase in protein content of thigh muscle, whereas it was statistically similar in breast muscles. No significant difference was observed in haematological parameters in broiler chicks of different treatment groups. There was significant (P<0.05) reduction in serum cholesterol in treatment groups T4 (149.59 mg/dl), T3 (143.75 mg/dl) and T2 (138.98 mg/dl) as compared to control T1 (166.03 mg/dl). Whereas, there was no significant difference in serum triglycerides, serum total protein, albumin, globulin and glucose concentrations and SGPT, SGOT and serum ALP activities among the different treatment groups, however, there was also considerable reduction in serum triglycerides content in broiler chicks fed diet containing aniseed and ginger rhizome powder. The feed cost/kg weight gain did no differ significantly amongst the different groups of broiler chicks. It is concluded that inclusion of 1.00 % aniseed or 1% ginger rhizome powder in the diet of broiler chicks improved nutrient utilization, increase in protein content in thigh muscles and fat content in breast muscles and reduced serum cholesterol and triglycerides content which in turn is beneficial in producing the designer meat in broiler chickens as growth performance, haematological parameters and carcass characteristics and also the economics of broiler production were statistically similar in all the treatment groups.ThesisItem Open Access Effect of feeding Tinospora cordifolia and Mentha arvensis on growth, nutrient utilization and haemato-biochemical constituents in crossbred calves(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-07) Ritu Raj; Rahal, AnshuThe research was conducted in twenty crossbred calves (6-12 months of age) selected from the herd of Instructional Dairy Farm, Nagla and divided into four groups of five each on the basis of their body weight after observing 10 days of adaptation period and experimental feeding was of 90 days. All the calves were provided with mixed green fodder and concentrate mixture. In addition, Group II was provided with Tinospora cordifolia @ 4% of concentrate, group III was provide with Mentha arvensis @ 4% of concentrate and group IV was provided with both Tinospora cordifolia and Mentha arvensis @ 2% of concentrate each. The dry matter intake, dry matter intake/W0.75, TDN intake/W0.75 and DCP intake/W0.75 in group III was significantly (P<0.05) higher than group I but no significant difference was found in group II and IV. The digestibility coefficient of nutrients like DM, OM, CP, EE, NFE, CF, NDF and ADF was not significantly different among the groups but in group III the digestibility of various nutrients was slightly lower than other supplemented groups. Body weight gain was significantly higher in group IV than group I and III. Hematological constituents like TEC%, TLC%, lymphocytes%, monocytes% and basophils% did not differ significantly among the groups but hemoglobin (g/dL), neutrophils% and PCV% in group II was significantly (P<0.05) higher than other groups. The eosinophils were significantly higher in group III fed with mentha arvensis @ 4% of concentrate than other groups. Biochemical constituents and rumen metabolites like glucose, total protein, serum albumin, serum globulin, albumin: globulin ratio, triglycerides, urea, cholesterol and rumen pH, total nitrogen and total VFA’s were not affected significantly among the groups. It can be concluded that the feeding of Tinospora cordifolia @ 4% of concentrate is beneficial for crossbred calves as it has increased the weight gain, haemoglobin (g/dL), PCV% and neutrophils% (within the normal range) which leads to increase phagocytic activity, Mentha arvensis feeding @ 4% of concentrate is beneficial in increasing appetite as it has increased the dry matter intake, dry matter intake/W0.75, TDN intake/W0.75 and DCP intake/W0.75 in crossbred calves. Tinospora cordifolia and Mentha arvensis combination @ 2% of concentrate is beneficial in increasing body weight as it has increased the final body weight and body weight gain per day in crossbred calves.ThesisItem Open Access Effect of supplementation of different types of mineral mixture on blood biochemical profile, weight gain and nutrient utilization in local goats(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2008-07) Singh, Neelam; Rahal, AnshuIn India, mineral mixtures for feeding ruminants are available in market under various trade names. In the present experiment, three types of mineral mixtures were used as selective mineral mixture, Mineramin and Minfa. 20 local goats were used to study the effect of supplementation of different types of mineral mixture on nutrient utilization, body weight gain, blood biochemical profile and evaluation of its economic value. The Goats divided in four groups of 5 each on BW basis (initial BW 18- 20 kg, 1.5-2.0 years) were given mineral mixture @ 2% of the concentrate mixture along with basal ration. DM and DCP intake showed significantly (PThesisItem Open Access Effect of feeding shatavari (Asparagus racemosus) and saijan (Moringa oliefera) on nutrients intake, digestibility and milk production in crossbred lactating cows(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2008-08) Mishra, Indu Shekhar; Jaiswal, R.S.Since hundreds of years livestock is an integral part of mixed farming system. The ancient history of India is very rich in herbal medicines. Animal productivity in terms of growth and milk yield can be improved by using different herbs as a component of animal feed.

Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-08) Salame, AartiA feeding trial was conducted to discern the effect of dietary supplementation of mannan-oligosaccharides and citric acid on growth performance, nutrient utilization, carcass traits and haemato-biochemical parameters in commercial broiler chickens. A total of 100, dayold broiler chickens were divided randomly into 5 treatment groups with 2 replication each i.e. 10 broiler chickens per replicate. Chickens of treatment T1 (control) were fed basal diet (starter and finisher diet), whereas in treatment groups T2, T3, T4 and T5, basal diet was incorporated with 0.1% mannan-oligosaccharides (MOS), 0.2% citric acid, 0.05% MOS with 0.1% citric acid, and 0.1% MOS with 0.2% citric acid, respectively, as feed additive. The feeding trial lasted for 42 days viz., 0-21 days (starter phase) and 21-42 days (finisher phase). A metabolism trial was conducted during the 6th week of feeding trial. Blood samples were collected on 42nd day of feeding trial to study haemato-biochemical parameters. During the starter phase (0-21 days), the weight gain was improved significantly in broiler chickens of treatment groups T5 (469.85 g) fed diet is supplemented with 0.1 % MOS in combination with 0.2% citric acid followed by T4 (452.75 g) fed diet supplemented with 0.05% MOS and 0.1% citric acid, T3 (443.40 g) fed diet supplemented with 0.2% citric acid as compared with T2 (425.85 g) fed diet supplemented with 0.1% MOS and T1 (390.75 g) fed diet supplemented with control diet. During 21- 42 days (finisher phase), the average body weight gain was 1025.3, 1062.8, 1118.0, 1235.6 and 1251.4 g in broiler chickens of treatment groups T1, T2, T3, T4 and T5 respectively and differed significantly among different groups. Feed intake was not differed significantly in broiler chickens of various treatment groups. Feed conversion ratio, performance index broiler chickens differed significantly among treatment groups. During entire feeding trial period (0-42 days), supplementation of MOS and citric acid in the basal diets improved growth performance in terms of body weight gain, feed conversion ratio, performance index. The average cumulative body weight gain was 1416.1, 1488.6, 1561.4, 1688.4 and 1721.3 g in broiler chicks of treatment groups T1, T2, T3, T4 and T5, respectively and differed significantly (P<0.05) among different groups. There was no significant difference in feed intake. The nutrient utilization improved significantly among different treatment groups of broiler chickens. The various carcass traits in broiler chickens were not affected but the breast and thigh part differed significantly due to feeding of MOS and citric acid. There was no significant differences in protein and ether extract content of breast and thigh muscles. No significant difference was observed in haematological parameters in broiler chickens of different treatment groups. There was significant (P<0.05) reduction in serum cholesterol in broiler chickens of treatment groups T5 (132.05 mg/dl) followed by T4 (133.02 mg/dl) and T2 (140.78 mg/dl) as compared with T3 and T1. Serum triglycerides content significantly reduced in all the treatment groups compared with control. There was no significant difference in serum total protein, albumin, globulin and glucose concentrations and serum ALP, ALT and AST activities among the different treatment groups. The dietary supplementation of MOS in combination with citric acid at both levels showed similar performance in broiler chickens. It can be concluded that inclusion of 0.05% mannan-oligosaccharides and 0.1% citric acid in the diet of broiler chickens improved growth performance, nutrient utilization and reduced serum cholesterol and triglycerides which in turn is beneficial in broiler chickens.
