Composition and fatty acid profile of milk from cows supplemented with pressed oilseed cake

Abstract

This study compared the productive and nutritional parameters of milk from crossbred lactating cows managed on Panicum maximum Jacq. cv. Tanzania and with a diet supplemented with different pressed oilseed cakes. The supplements used were as follows: peanut cake, sunflower cake and palm kernel cake for replacement of soybean meal. Sixteen cows with an average weight of 544 ± 57 kg and producing 8 ± 1.4 L of milk per day were used in this study. The animals were randomly assigned to the treatments according to a Latin square design repeated over time, with four treatments, 16 animals and four experimental periods. Supplementation of the diet with peanut cake, sunflower cake and palm kernel cake compared with soybean meal in the diet of cows did not affect the average daily production or composition of the milk. The palm kernel cake promoted an increase in lauric fatty acids (C ) and palmitoleic acids (C ) (5.02 and 1.65%, respectively) compared with peanut cake and sunflower cake (4.13 and 4.01%, respectively). The levels of oleic fatty acids (C ) were higher for the sunflower cake and palm kernel cake supplements (26.01 and 25.01%, respectively) compared with peanut cake (23.11%). The replacement of soybean meal with sunflower cake and palm kernel cake improved the nutritional quality of the milk, with lower concentrations of saturated fatty acids and higher concentrations of unsaturated fatty acids, without compromising the production or nutritional composition of the milk. © 2015 Japanese Society of Animal Science.

Use of Cold-Pressed Sunflower Cake in the Concentrate as a Low-Input Local Strategy to Modify the Milk Fatty Acid Profile of Dairy Cows

“…Feeding CPSC induced a decrease in the percentages of C12:0 and C16:0 and an increase of C18:0 in milk fat. This is in agreement with results of recent studies in dairy cows fed sunflower cake [23] and dairy sheep supplemented with CPSC [5] or sunflower oil [6]. The lower content of C12:0 and C16:0 in milk can be primarily accounted for their lower contents in CPSC diet, but also for the increased supply of long-chain FA, mainly linoleic acid, that might have a potential inhibitory effect on de novo synthesis of short and medium chain SFA in the mammary gland of CPSC-fed cows [24].…”

The effect of dietary oilseeds on physico-chemical characteristics, fatty acid profile and sensory aspects of meat of young zebu cattle

“…The carcasses were identified and sawn along the spine, weighed to obtain the hot carcass weight (HCW) and cooled to 0 °C to 2 ºC for 24 h. After cooling, the subcutaneous fat thickness (SFT) was measured in the region between the 12th and 13th ribs, using a digital caliper.
