Effect of Feeding Urea-treated Sugarcane Tops on Production and Composition of Milk in Phule-Triveni Crossbred Cows
The study was conducted in Western Maharashtra State of India on Phule Triveni lactating cows to investigate the effect of feeding a diet containing urea-treated sugarcane tops on milk yield and milk composition.Sixteen lactating cows were used and arranged in a 4×4 Latin square design.The daily dry matter requirement of experimental cows was fixed at 3% body weight of the cows and the treatment diets consisted of concentrate and roughage at a proportion of l/3 and 2/3 part of the ration (dry matter hasis),respectively.The concentrate portion of the diet was similar for all treatments.The roughage dry matter proportion of the treatments were T0 (30% untreated sugarcane tops,20% green maize,30% green lucerne and 20% sorghum straw),T1 (30% from 4% urea-treated sugarcane tops,20% green maize,30% green lucerne and 20% sorghum straw),T2 (45% from 4% urea-treated sugarcane tops,15% green maize,20% green lucerne and 20% sorghum straw)and T3 groups consisted of 60% from 4% urea-treated sugarcane tops,20% green lucerne and 20% sorghum straw.There was no significant difference (P>0.05)among treatments in respect of milk yield and milk constituents (protein,fat.TSS.SNF and calcium).Diets with 45% UTSCT (T2)and control group (T0 )were the best and the least treatments,respectively in respect of economic profitability.Higher net income was ohserved in all urea-treated sugarcane top based diets than the control diet.It can be concluded that urea-treated sugarcane tops can be incorporated up to 45% of the roughage requirement in the diet of lactating cows for better milk production and profitahility with out affecting the milk composition.
