Milk fat composition in supplemented B. taurus x B. indicus cattle

Abstract

Eight cows grazing star grass (Cynodon nlemfluensis) were divided into four supplement treatments: Control 3 kg/day soyabean meal/sorghum supplement (16% CP), HP: high protein (2 kg soyabean meal, 1 kg sorghum, 31.5% CP), HE: high energy (1 kg sorghum, 2 kg Ca-soap) and HPE: high protein-high energy (2 kg Ca-soap, 1 kg soyabean meal). Treatments were balanced in two 4 x 4 Latin squares groups as cows received or not supplement during the dry period (3 kg 18% CP). None of the dietary treatment had an effect on the milk fat composition (P>0.05). Further research is needed to evaluate the magnitude of the influence of the genetic dairy potential of type of cows on the observed results.
