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 […]
Keywords: egg quality; laying hen; lipid metabolism; mineral supplementation; serum parameters

ABSTRACT The objective of this study was to evaluate sequential digestible phosphorus levels for gilts from 30 to 100 kg. Sixty gilts were used, with an initial weight of 29.98±3.37 kg and final weight of 100.66±8.82 kg, distributed in a randomized block design, with five nutritional digestible phosphorus levels: 2.19-1.88-1.68, 2.69-2.38-2.18, 3.19-2.88-2.68, 3.69-3.38-3.18, and 4.19-3.88-3.68 g kg−1, respectively, for the growth phases 30 to 50 kg, 50 to 70 kg, and 70 to 100 kg, with six replicates and two […]

The ponderal performance of heifers under rotational grazing fed two types mineral supplement was evaluated. A total of 25 heifers Holstein × Zebu, including nine regulator animals and 16 test animals, was divided into four treatments: mombaçagrass (Panicum maximum, CV. Mombaça) with selective salt (MSS), mombaçagrass with commercial salt (MSC), elephantgrass (Pennisetum purpureum, CV. Napier) with selective salt (ESS) and elephantgrass with commercial salt (ESC). Average daily live weight gain (DWG) was calculated by weighing the test animal every 28 […]

Forty-eight crossbreed beef cattle were used to evaluate four commercial mineral supplements: Treatment A- Salt + protein without urea (20% crude protein); B – salt + protein with urea (52,5 % crude protein), C) mineralized salt; D) mineralized salt with urea (91% crude protein). The animals were distributed into 24 plots of Braquiaria decubens grass, with supplementation of (10.5 kg/an/day) of sugar cane, during 112 days, with 28 days of adaptation and 84 days of data collection. The animals were […]
