Profile of milk fatty acids from moxotó goats fed with different levels of manicoba (Manihot Glaziovii Muel Arg.) silage

Abstract

The objective of this work was to evaluate the effects of the manicoba silage use (Manihot glaziovii Muel Arg.) in different roughage:concentrate ratios (30:70; 40:60; 50:50 and 60:40 %)

Influence of Sunflower Whole Seeds or Oil on Ruminal Fermentation, Milk Production, Composition, and Fatty Acid Profile in Lactating Goats

“…Moreover, both of SO and SS had increased C18:2 trans-10, cis-12, C18:3N3 and total CLA concentrations compared to Control ( Table 5 ). Fatty acids can be originated from plasma (60%) or by the synthesis in the mammary gland from acetate and hydroxybutyrate originated from rumen fermentation involving acetyl CoA carboxylase enzymes and fatty acid synthetase ( Mesquita et al, 2008 ; Kholif et al, 2014 ). Polyunsaturated FA are not synthesized by ruminants, so that their concentration in milk depends on the amount of PUFA absorbed from the intestines.…”

“…Fatty acids originated from plasma (60%) or by the de novo synthesis in the mammary gland from acetate and 2 -hydroxybutyrate originating from rumen fermentation involving acetyl CoA carboxylase enzymes and fatty acid synthetase ( Mesquita et al, 2008 ). Polyunsaturated acids are not synthesized by ruminants, so that their concentration in milk depends on the amount of them absorbed from the intestines.…”

Effects of feeding a Moringa oleifera rachis and twig preparation to dairy cows on their milk production and fatty acid composition, and plasma antioxidants

“…Milk FA originate mainly from plasma uptake (∼60%) or by de novo synthesis in the mammary gland from acetate and 2-hydroxybutyrate derived from rumen fermentation. 8,35 The change in milk FA profile that we found may be related to phenolic species found in our moringa supplement, which would be expected to inhibit the biohydrogenation process and, consequently, growth of Butyrivibrio fibrisolvens and Ruminococcus albus, thereby altering the FA profile of the cow milk. 20,36,37…”
