| dc.description.abstract | ABSTRACT Present study was designed to evaluate the effect of prill fat and protected choline supplementation on performance of lactating Murrah buffaloes. Murrah buffaloes (n=18) were divided into three groups of six each, based on milk yield, fat per cent and stage of lactation. All buffaloes were fed similar basal diet, comprising 12-15 kg green fodder, 8-10 kg wheat straw and concentrate mixture. Concentrate mixture was given according to the level of milk production to meet the requirements for maintenance and milk production as per feeding standard given by Kearl, 1982. Buffaloes in group T1 were daily supplemented with prill fat @ 2.5% of total DMI per animal whereas, buffaloes in group T2 were supplemented with 54 g protected choline along with prill fat fed @ 2.5% of total DMI per animal. Feeding trial was conducted for 90 days. Observations regarding daily feed intake, daily milk yield, fat per cent etc. were recorded during the experiment. Body weights and body condition score of each buffalo under different groups were recorded at the start and at completion of experiment. Milk samples were collected on 30th day, 60th day and 90th day from each buffalo in different treatment groups and were analyzed for its composition. Blood samples were collected from all the experimental buffaloes at 0 day and at the end of experiment to estimate various blood biochemical parameters including NEFA. Economics of milk production over feed cost was also calculated in different treatment groups. Average daily dry matter intake (kg/d) and body weight (kg) of buffaloes were not affected by supplementation of either prill fat or prill fat along with protected choline but BCS was improved due to supplementation. After supplementation of with prill fat alone or with RPC the average milk yield (kg) and milk fat (%) of lactating Murrah buffaloes were increased significantly (p<0.01) by 0.99 kg and 0.41 units and 1.78 kg and 0.73 units in T1 and T2 groups, respectively as compared to the control. The average 4% FCM (kg/d), ECM (kg/d) and fat yield (kg/d) was significantly (p<0.01) higher in T2 followed by T1 and control groups. There was no difference in milk composition except milk fat (%) and total solids (%) which were improved significantly (p<0.01) in supplemented groups. NEFA concentration (mmol/l) in the blood was decreased significantly (p<0.01) by 5.0 and 9.0% in prill fat alone and prill fat along with RPC supplemented groups whereas, average blood triglyceride level (mg/dl) of respective groups were increased by 10.98 and 15.39%, as compared to control group. Supplementation of prill fat alone or along with RPC had no influence (p>0.01) on blood glucose and cholesterol levels of buffaloes. Net profit/animal/day (Rs.) was 8.25 and 3.12% higher in T2 and T1 groups than control. The study revealed that prill fat supplementation in the ration helped in improving performance of early lactating Murrah buffaloes by increasing milk yield and fat percent which can be further enhanced by supplementing the ration with rumen protected choline. | en_US |
