ABSTRACT This study evaluated the effects of chromium yeast (Cr yeast) and two apparent metabolizable energy (AME) levels on productive performance, egg quality, and lipid and carbohydrate metabolism in laying hens. A total of 192 Bovans White laying hens at 47 weeks of age were randomly assigned to eight dietary treatments (six replicates each) in a 4 × 2 factorial arrangement: four levels of supplemental Cr (0, 0.2, 0.4, and 0.8 ppm as Cr yeast) and two AME levels (2,780 […]

ABSTRACT This study was conducted to investigate the effects of dietary fats (tallow [TO] or linseed oil [LO]) or conjugated linoleic acid (CLA), singly or in combination, on laying performance, yolk lipids, and fatty acid composition of egg yolks. Three hundred 50-week-old laying hens were given one of five diets containing 2% TO; 1% TO + 1% CLA (TO/CLA); 2% LO; 1% LO + 1% CLA (LO/CLA); and 2% CLA (CLA). Laying performance, egg lipids, and serum parameters were not […]

A total of 60 barrow pigs (89.1 ± 4.2 kg) was used to evaluate five levels (0, 5, 10, 15 and 20%) of qualitative feed restriction, resulting in values of 3,407, 3,420, 3,060, 2,890, and 2,720 kcal/kg DE in the diet. Ten animals were slaughtered at the beginning of the experiment to determine the initial body composition, while the others were fed with the experimental diets until reaching 128 kg of body weight. A randomly block design was used to […]
