effect of feeding canola or sunflower seeds on conjugated linoleic acid enrichment in cow’s milk fat
two experiments studied the effects of canola or sunflower seed supplementation on conjugated linoleic acid (cla) concentration in milk fat of lactating cows. in each experiment, only eight cows in early lactation were available to assign to one of two treatments in a completely randomized design and were fed individually for 12 wk. experiment 1 compared similar diets with or without the additi...
This study was carried out to compare the effects of ewe milk with commercial milk replacer and starter diet with different levels of concentrate on microbial protein synthesis, ruminal fermentation and blood metabolites in the suckling lambs. Thirty Dalagh breed male lambs were separated from their mothers on 3±1 days of age and divided into 6 groups (5 lambs per treatment), and reared in indi...
BACKGROUND The mammary gland is a conserved site of lipoprotein lipase expression across species and lipoprotein lipase attachment to the luminal surface of mammary gland vascular endothelial cells has been implicated in the direction of circulating triglycerides into milk synthesis during lactation. PRINCIPAL FINDINGS Here we report generation of transgenic mice harboring a human lipoprotein...
Two experiments were conducted with Polypay ewes nursing twin lambs to evaluate the effects of supplementing fat (calcium salts of palm oil fatty acids or hydrogenated tallow) on ewe lactation. In Exp. 1, ewes were fed a 52% concentrate:48% hay-based diet (as-fed basis) consisting of alfalfa hay (n = 4), endophyte-free fescue hay (n = 4), or fescue hay with 3.7% fatty acids (n = 4) from d 4 to ...
Two experiments were conducted to evaluate responses of primiparous and multiparous Holstein cows to diets containing wet corn gluten feed (WCGF). In both experiments, WCGF replaced a mix of alfalfa hay, corn silage, and corn grain. In experiment 1, 32 primiparous Holstein cows (four pens with eight cows/pen) were used in two 2 x 2 Latin squares with 28-d periods. Cows were housed in free stall...
Dairy products provide abundant, accessible calcium for humans, while some calcium sulfate-rich mineral waters could provide appreciable amounts of calcium. But there is little evidence that this calcium is as available as milk calcium for making bone. The availability of calcium was studied by monitoring bone parameters in 2-month-old pigs fed restricted amounts of calcium (70% RDA) for 2.5 mo...
Two experiments were conducted with lactating Angus x Gelbvieh beef cows to determine the effects of postpartum lipid supplementation, BCS at parturition, and day of lactation on fatty acid profiles in plasma, adipose tissue, and milk. In Exp. 1, 36 pri-miparous cows (488 +/- 10 kg of initial BW; 5.5 +/- 0.02 initial BCS) were given ad libitum access to hay and assigned randomly to a low-fat (c...
Cross-linking of lignin to arabinoxylan by ferulates limits in vitro rumen digestibility of grass cell walls. The effect of ferulate cross-linking on dry matter intake (DMI), milk production, and in vivo digestibility was investigated in ad libitum and restricted-intake digestion trials with lambs, and in a dairy cow performance trial using the low-ferulate sfe corn mutant. Silages of 5 inbred ...
(1) Background: Late preterm infants account for the majority of preterm births and are at risk of altered body composition. Because body composition modulates later health outcomes and human milk is recommended as the normal method for infant feeding, we sought to investigate whether human milk feeding in early life can modulate body composition development in late preterm infants; (2) Methods...
OBJECTIVE Quantitative balance studies were performed to compare fat and calcium absorption in healthy, full term infants fed casein hydrolysate-based (CHF) and soy protein-based (SPF) infant formulas with or without palm olein (PO). Previous studies have reported that PO significantly reduced absorption of both fat and calcium in cow's milk-based formulas in which most of the calcium is inhere...
