Abstract:
In the present study grains, oil seed cakes, agroindustrial by-products and soya pulp were analysed for proximate principles, cell wall constituents and mineral content (Ca and P). Twenty cows of same parity, age and average milk yield (15-25 litres per day) were distributed in four treatment groups (T₁, T₂, T₃ and T₄) of five animals each. Cows in all the groups were fed basal diet consisting of maize fodder, maize silage, concentrate mixture and wheat straw as per NRC (2001). The soya byproducts (soybean cake and full fat soya) in the concentrate mixture were replaced with soya pulp at 0%, 10%, 20% and 30% levels on N-basis in groups T₁, T₂, T₃ and T_4, respectively. All the diets were iso-nitrogenous. The animals of group T₁ served as control. Economics of replacement of soya byproducts in the concentrate mixture with soya pulp was calculated. It was concluded that soya pulp supplementation reduced the cost of feed and milk production.
