Abstract

1. In a 3 X 3 Latin square design 9 cows were given long hay and a concentrate without supplemental fat or with 12% fat (11% tallow and 1% palm kernel oil) mixed with other ingredients or adsorbed on a carrier of Palabora vermiculite. During the 3rd week of treatment milk production was 21.4, 23.5 and 22.6 kg daily, respectively. With both fat-supplemented concentrates, milk fat content increased initially but then decreased sharply and was 3.55, 3.18 and 3.91% in week 3. At the same time protein was 3.19, 3.07 and 3.09%. Feed intake of cows given the fat supplements decreased. (Abstract retrieved from CAB Abstracts by CABI’s permission)
