    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-06) Bhadruriya, Mohit Kumar Singh; Ashoka Kumar
    A feeding trial was conducted to discern the effect of dietary incorporation of ground fenugreek (Trigonellafoenum-graecum) seeds and turmeric (Curcuma longa)rhizome powder on growth performance, nutrient utilization, haemato-biochemical parameters, carcass traits and sensory evaluation in commercial broilers. A total of 100, day-old broiler chicks were divided randomly into 5 treatment groups with 2 replicates each i.e. 10 broiler chicks per replicate. Chicks of treatment T1 (control) were fed basal diet without any supplementation, whereas in treatment group T2, T3, T4 and T5,basal diet was supplemented with 1.0% fenugreek seed, 0.5% turmeric rhizome, 1.0% fenugreek plus 0.5% turmeric and 0.5% fenugreek plus 0.25% turmeric,respectively. The feeding trial lasted for 42 days viz., 0-21 days (starter phase) and 2242 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 trail indicate that during the starter phase (0-21 days), the body weight gain of broiler chicks of treatment group T4 (673.70 g) was significantly (P<0.05) higher than other treatment groups T1 (626.40g), T2 (647.30g)and T3 (646.10g). There was no significant difference in body weight gain between T4and T5. During 22- 42 days (finisher phase), the body weight gain of broiler chicks of treatment group T4 (1300.30g) was significantly (P<0.05) higher than other treatment groups T1 (1089.80g), T2 (1170.90g) and T3 (1213.00g). There was no significant difference in body weight gain between T4 and T5.FCR and performance index were improved in broiler chicks of treatment groups T4and T5. During whole experimental period (0-42 days),supplementation of fenugreek seed plus turmeric rhizome powder improved broiler performance in terms of feed intake, body weight gain, FCR and performance index. The average cumulative body weight was 1759.00, 1861.14, 1902.00, 2052.20 and 2006.80g in broiler chicks of treatment groups T1, T2, T3, T4 and T5, respectively and differed significantly (P<0.05) among different groups. Nutrient utilization in terms of dry matter, crude protein andcrude fatwas significantly (P<0.05) improved in broilers fed diet supplemented with fenugreek seed and turmeric rhizome powderas compared to control. There was significant (P<0.05) improvement in protein content and reduction in fat content of breast and thigh muscles. Significant (P<0.05) difference were observed in haemoglobinand packed cell volume in broilers of supplemented groups. Significant (P<0.05) reduction in serum cholesterol, serum triglyceride and glucose level were recorded in broilers of treatment groups. Whereas, there was non-significant difference in serum total protein, albumin, globulin level.Serum enzymes activity viz., ALP, SGPT and SGOT showed non-significant difference among the broilers of treatmentgroups. It is concluded that incorporation of 0.5% fenugreek plus 0.25% turmeric rhizome powder in basal diet of broilers improved growth performance, nutrient utilization, increase haemoglobin,packed cell volumeand reduced serum cholesterol, serum triglyceride, serum glucose level,along with increased amount of protein and decreased fat content in thigh muscle. which in turn is beneficial in producing the designer meat in broiler chickens.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-08) Salame, Aarti
    A 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.

    Effect of feeding black soybean on feed intake, nutrient utilization, egg composition and haemato-biochemical constituents in poultry layers
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-07) Joshi, Jyoti; Rahal, Anshu
    An experiment was conducted on 100 layers (20 weeks old) to discern the effect of feeding black soybean on feed intake, nutrient utilization, egg production and composition, haemato-biochemical constituents and histopathological changes. A twelve week feeding trial was conducted in a completely randomised block design. The experimental birds were randomly divided into five treatment group’s viz. T1: Control; T2: 0.2% raw black soybean; T3: 0.2% germinated black soybean; T4: 0.2% roasted black soybean and T5: 0.2% cow urine treated black soybean. production performance was studied in three different phases viz., Phase I (20-24 weeks), Phase II (25-28 weeks) and Phase III (29-32 weeks). At the end of feeding trial a metabolic trial was conducted to know the nutrient utilization. Highest egg production was recorded in group T5. Highly significant (P≤0.01) difference was observed in feed intake in phase II, III and overall phase as well as in crude protein of egg and serum cholesterol. Significant differences (P≤0.05) were observed among the different treatment groups in egg production in phase III, feed intake in phase I; dry matter, crude protein and ether extract utilization; egg weight, shell thickness; ether extract, ash and cholesterol content of egg and in serum glucose. The least histopathological changes were observed in the group fed cow urine treated and roasted black soybean. From the present study it may be concluded that cow urine treated black soybean up to the level of 0.2% incorporation can be recommended for improving performance in layers.
