Effect of varying levels of concentrate on growth performance and feed economics in Nili-Ravi buffalo heifer calves

Abstract

An experiment was conducted to optimize the effect of concentrate levels on growth performance in Nili-Ravi buffalo heifers.These animals (n = 30), aged 4 6 months, were divided into three treatment groups (A, B, C) and were offered concentrate at the rate of0.5%, 1.0%, and 1.5% of body weight for an 8-month period, respectively. The statistical data showed a significant (P < 0.01) effect on drymatter intake among all treatment groups. However, dietary treatments showed a nonsignificant effect on body weight gain. TreatmentA showed a better (P < 0.01) feed conversion ratio (10.01 ± 0.55) compared to treatment B (11.75 ± 0.79) and C (12.85 ± 0.74). Theaverage body condition score, body measurements, and blood profiles were not affected by varying levels of concentrate. However, totalserum protein was found lower (P < 0.01) in treatment A compared with the other two treatment groups. The cost for production per kggain was 80.8% higher in treatment C and 46.6% higher in treatment B compared to treatment A. It can be concluded that buffalo heiferscan be reared cost-effectively on a minimum concentrate level (0.5% of body weight) along with ad libitum green fodder.
