Growth and feed conversion of Boran (Bos indicus) and Holstein X Boran heifers during three physiological states receiving different levels of a tropical diet
Forty-eight heifers of two genotypes, Boran (Bos indicus) and Holstein×Boran, were allocated to three feeding levels equivalent to 1.0, 1.2 and 1.4 times calculated metabolisable energy requirements for maintenance (MEm). The experiment started at the onset of reproductive activity, when the Boran a...
