Abstract

The aim of this study was to evaluate the fatty acid composition of buffalo milk in the first eight weeks oflactation. It was used 18 cows multiparous Buffaloes of Mediterranean race, the data collection starting four weeksbefore of the calving provided by the 8th week of lactation. The animals were mechanically milked once daily in themorning. The milk samples used for composition analysis were collected weekly from parturition to eight weeks oflactation. There was effect of weeks during the transition period and early lactation for fat yield (kg/day) and for bodyweight of the buffalo cows in lactation (kg).There was effect of weeks of lactation on the fatty acid composition of milkfat.Variations in levels of unsaturated fatty acids of milk fat of buffaloes are similar to those found in dairy cows of thepartum to eighth week of lactation.

Abstract

This study was carried out to evaluate the use of different fat sources in dairy cows rations and its effects on dry matter intake, milk yield and composition, and blood parameter. Twelve Holstein cows were allocated in three balanced latin square 4x4, and fed with the following rations: 1) Control, with 2.5%; 2) Refined soybean oil; 3) Whole soybean; and 4), Calcium salts of fatty acids (Megalac-E). The concentrations of total cholesterol and lipoprotein low density (LDL) were higher (P<0.05) for cows that received rations with fat sources, which also causes increased (P<0.05) e concentration of high density lipoprotein (HDL). The concentrations of urea and blood urea nitrogen were similar among the rations, except for the diet containing calcium salts of fatty acids, which showed lower (P<0.05). The dry matter intake was lower (P<0.05) in cows that received calcium salts in the rations. The animals that received a diet containing whole soybeans as a source of fat had lower (P<0.05) yield milk when compared to other rations used. The use of fat sources in dairy cows rations influenced the blood parameters, especially for parameters related to lipidogram. [ABSTRACT FROM AUTHOR]
