ABSTRACT The study was carried out with the objective of investigating the enrichment of weaned piglet diets with selenium proteinate (SeP) and sodium selenite (SeS) at two inclusion levels. A total of 40 piglets, averaging 6.60 ± 1.06 kg, were assigned to five dietary treatments: a control diet, and diets supplemented with selenium proteinate (0.15 or 0.30 mg/kg) or sodium selenite (0.15 or 0.30 mg/kg). The SeP-0.30 diet reduced average daily feed intake (ADFI) (P

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 […]
