ThesisItem Open Access Effeets of Moringa oleifera Leaf Meal supplementation on Production, Stress Amelioration & Economics of Black Rock Chicken under Intensive Production System(2022) Palit, Smita; Bera, Santanu; Biswas, C.K.; Samanta, Rajarshi; Ghosh, Nilotpal; Mandal, Guru Prasad; Sarkar, UttamThe current research work was accomplished to study the effects of Moringa oleifera leaf meal (MOLM) supplementation on production, stress related traits of Black Rock Chicken under intensive production system and its economic feasibility. The experiment was conducted for a period of 53 weeks of birds aged between 20th to 72 weeks. Total 400 nos. of Black Rock pullets were allocated randomly in four groups of 100 birds. Each groups were divided into 4 replicates. In control group (T0) birds were fed commercially available layer mash and in treatment groups such as T1, T2 and T3, the birds were fed with Moringa oleifera leaf meal (MOLM) at the levels of 1.0%, 2.0% and 5.0 %, respectively. Results revealed that the dietary supplementation of MOLM has significant effect (p<0.01) and (p<0.05 ) on egg production (Hen day egg production and Hen house egg production), feed consumption, feed efficiency, egg mass, egg weight, shape index, shell thickness, shell %, albumen weight, albumen index, albumen %, Haugh unit, yolk weight, yolk index. The yolk % of egg was not differ significantly. Serum biochemical profile, cortisol, H:L, cholesterol, calcium, phosphorus and potassium were found significant difference except sodium. Glucose, total protein, albumen, globulin, creatinine, uric acid and triglyceride levels were found significantly different [(p<0.01) & (p<0.05)] in all phases i.e. Phase I (20th to 39th weeks), Phase II (40th to 59th weeks) and Phase III (60th to 72 weeks). However, uric acid and globulin was found to be non significant at 20th to 39th weeks and 60th to 72 weeks of age, respectively. All hematological parameters were found significant difference except WBC in 40th to 59th weeks of age. Antioxidation of enzyme revealed significant result except catalase. Fecal bacterial count showed significant difference (p<0.05). Mortality percentage was found very low at 2% MOLM and negligible in 5% MOLM followed by other groups. Economic returns were found to be more beneficial at 5% MOLM (T3) with less cost of feed for egg production than other treatment groups. Overall mean value for feed consumption per day per bird and feed consumption by per bird during whole experiment period observed significantly high in control group and lowest in 5% MOLM (T3) treatment group. So, in control group cost of feed very high compare to Moringa oleifera supplemented treatment groups. Overall average egg production per bird observed significantly high (p<0.05) in T3 (5% MOLM) group. Due to this reason market sale price of eggs also increases according to average egg production and significantly highest (p<0.05) sale price observed in T3 (5% MOLM) group. Overall cost of feed per egg produced observed significantly high (p<0.05) in control group and gradually decreases as the MOLM level increases and lowest cost of feed per egg produced observed in T3 (5% MOLM) group for all Period. The cost price of Moringa oleifera leaf was free because moringa leaf is available in nature in abundance and its non-availability in the market for sale, the cost of moringa leaf as such not considered for present study. The dietary supplementation of Moringa oleifera leaf meal (MOLM) at 1%, 2% and 5% level in the diet of Black Rock Chicken for whole experimental study (20 weeks to 72 weeks) period i.e. 20th to 29th weeks, 30th to 39th weeks, 40th to 49th weeks, 50th to 59th weeks and 60th to 72 weeks had been observed very good results on the production performance (increased Hen day egg production, Hen house egg production, egg mass and FCR), improves egg quality parameters (both external and internal egg quality) and organoleptic/sensory attributes (achieve very good to excellent score on Hedonic scale of calculation). Results revealed positive effect for reducing stress and improving health status. For overall performance the feed cost per egg was significantly (P<0.01) lower in T3 (5% MOLM) with high average egg production and high market sale price for up t o 5 % Moringa oleifera leaf meal (MOLM) supplemented diet in Black Rock Chicken. According to present results it may strongly concluded that cost of production reduced more in 5% MOLM supplementation and it was found economically feasible however the cost of feed also reduced in 1% and 2% MOLM groups also but not as like in 5% MOLM group.ThesisItem Open Access Formulation of A Suitable Pig Milk Replacer for Neonatal Piglets and Its Effect on Growth Performance in Ghoongroo Pig(West Bengal University of Animal & Fishery Sciences, Kolkata, 2023-03) Kumar, Ajit; Ghosh, Nilotpal; Biswas, Chanchal; Naskar, Shyamal; Samanta, Rajarshi; Bera, Santanu; Chatterjee, Paresh Nath; Batabyal, SubhasisThe pig is the most efficient feed-converting animal among all domesticated livestock species. It plays a pivotal role in improving the socioeconomic status of the tribal masses and weaker sections of India. The present study aimed to investigate the effect of feeding formulated milk replacer to piglets from the 3rd day till weaning age (56th day) on their growth performance, blood biochemical profile and stress physiology as compared to piglets reared conventionally on sow milk of Ghoongroo piglets in the tropical lower Gangetic region. The experiment was conducted on 20 Ghoongroo piglets divided into four groups, each containing 5 piglets, i.e., 3 treatment groups and 1 control group maintained at livestock farm ERS-IVRI, Kolkata. Growth performance showed a significant difference (P< 0.05) in body weight on respective recorded days of age between treatment and control groups, average body weight (kg) at 56th day of age of control (C) and treatment groups (T1, T2, T3) was found to be (10.17 ± 0.31, 18.02±2.66, 19.52 ± 0.44, 16.75 ± 0.40) respectively and average daily weight gain (g) had been found as (162.68 ± 5.55, 302.82 ± 47.76, 329.57 ± 7.67, 280.14 ± 6.99) respectively, which differs significantly (P<0.05). Day of feeding, treatment groups and treatment*day interaction showed a significant effect (P< 0.01) on the volume of milk and creep feed feeding of piglets between groups. Blood biochemical profile mainly haemoglobin values showed higher values in treatment groups compared to control group piglets and showed a significant increase (P< 0.05) in the treatment group compared to the control group. Also feeding milk replacers showed higher economic returns compared to conventional rearing methods. So, it can be concluded that feeding pig milk replacer powder @ 150g mixed in 1 litre of lukewarm water and fed 8-10 times a day to piglets from the 3rd day of age till the 56th day of age showed a highly positive impact on their growth performance, haemato-biochemical profile and stress physiology along with that it also resulted in better economic returns in pig rearing practicesThesisItem Open Access STUDIES ON SOME ASPECTS OF ADULT BEHAVIOUR OF FOWL ON DEEP LITTER(kolkata, 2011) MODHUKOILYA, AYUSHMAN; Samanta, Prof. A.
