Abstract:
A lactation trail was conducted to assess the impact of ration balancing technology on milk production and milk fat percentage in selected dairy cattle by evaluating their nutritional requirement. Twenty crossbreed dairy cows of comparable body weights were selected. The milk yields and fat percentage were recorded, initially for 30 days before implementing Ration Balancing Programme (RBP) and 30 days after implementing Ration balancing Technology. Animals were registered after ear tagging the animals and details like breed, stage of lactation, age of animals, pregnancy stage, calving date, milk yield and fat % recorded in RBP software. Initial nutritional requirement was calculated and available feed ingredients were also recorded along with cost and present feeding quantity. Least cost formulation prepared with the help of software and formulated ration recommended to the dairy farmers by providing physical advisory slips. Average milk yield and fat percentage (per day per animal) in the beginning for one month before starting the trial were 5.15 lit and 4.23 percent respectively. After starting the trial the data of milk yield and fat percentage recorded for one month, which is 6.15 and 4.44% for milk yield and Milk fat respectively, which shows there was positive impact of 1 litter and 0.21% on milk yield and fat percentage respectively. Hence it can be concluded that Ration Balancing Technology improves the milk yield as well as fat percentage of milk in crossbred dairy animals.
