Effect of prepartum feeding on milk yield and calf growth rate in limited-suckled and nonsuckled buffaloes.
Two experiments were conducted to measure response to prepartum feeding using 101 Nili-Ravi buffaloes of mixed ages and lactation numbers. Nutritional treatment was initiated approximately 75 d before calving and stopped at parturition. Levels of prepartum feeding were moderate and high in Experiment 1 and high and very high in Experiment 2. Estimated daily intakes of metabolizable energy by buffaloes on moderate, high, and very high intake treatments were 31.9, 45.8, and 50.6 Mcal, respectively. Prepartum feeding affected the BW gain by buffaloes in both experiments. Yields of milk and milk fat for first 75 d were greater for buffaloes on higher prepartum feeding treatments. In Experiment 2, buffaloes suckled for a limited time produced more milk than nonsuckled buffaloes, but the difference was small. Calf birth weight increased with increasing prepartum feeding in both experiments. Gain in BW of buffalo calves from birth to 75 d of age had no relationship with birth weight. In Experiment 2, calf weight gain was influenced by the interaction of dam's prepartum feeding and suckling. In conclusion, improvement in prepartum feeding can be used to increase milk yield and birth weight of Nili-Ravi buffaloes.
