The effects of different vitamin mixtures on growth performance, rumen fermentation parameters, serum metabolites, and heat stress biomarkers in Hanwoo heifers under high temperature-humidity condition.

Objective Heat stress impairs feed intake, metabolic balance, and productivity in cattle, and nutritional strategies are needed to maintain productivity under hot conditions. This study evaluated the effects of two complete commercial vitamin premixes on growth performance, rumen fermentation, blood profiles, and stres...

MODULATORY EFFECTS OF DIETARY GARLIC (Allium sativum) ON ANTIOXIDANT STATUS, LIVER FUNCTION AND PULSE RATE OF THREE BROILER GENOTYPES EXPOSED TO HEAT-STRESS

This study evaluated graded dietary garlic supplementation on antioxidant enzyme activities, liver enzymes, and pulse rate responses of three heat-stressed broiler strains (Arbor Acres, Cobb 500 and Ross 308). A total of 180 day-old chicks (60 per strain) were assigned to four garlic treatments (0, 1.0, 1.5 and 2.0%, T...

Effects of Dietary Kelp Enzymatic Hydrolysate Supplementation on Performance, Antioxidant Capacity, Immune Function, and Intestinal Health of Sows and Their Piglets

This study is the first to investigate the effects of dietary supplementation with kelp enzymatic hydrolysate (KEH) from day 85 of gestation to day 21 of lactation in sows. Twenty-four Landrace × Yorkshire sows were randomly assigned to four treatments: a control diet (0% KEH) and three experimental diets supplemented...
