Abstract

Abstract

This study was conducted to evaluate the effect of dietary baobab fruit pulp meal on milk physiochemical composition of lactating Bunaji, Wadara and Frisian x Bunaji cows at different parities under a tropical environment. The study was carried out at the Dairy Research and Development Centre (DRDC) of Abubakar Tafawa Balewa University, Bauchi. A total of 24 lactating cows at early, mid and late lactation were used for the research. The experimental cows were allotted to four dietary treatment diets: 0.00, 5.3, 10.6 and 15.9 kg/100kg diet of BFPM with six animals per treatment in a Completely Randomized Design. The data generated was subjected to analysis of variance using the SPSS software. The treatments were administered once daily after milking and lasted for 186 days. For laboratory analysis of milk composition and mineral contents, 100 mls of milk per cow was collected bimonthly. The results showed that protein was higher (P<0.05) in Bunaji and Wadara breeds. Fat was higher (P<0.05) in Bunaji and Friesian x Bunaji breeds. Total solid was higher (P<0.05) in Bunaji cows. Calcium and phosphorus were higher (P<0.05) in lactating cows fed 10.60 and 15.90 kg /100 kg baobab fruit pulp meal. In conclusion, BFPM inclusion in the diet of lactating cows significantly improved milk composition and mineral contents by maintaining the values within normal range under tropical environment. It is recommended that, under tropical conditions, BFPM should be included in the diet of lactating cows as antioxidants up to the rate of 15.9 kg/100 kg diet since it does not have any deleterious effect.
