An experiment was carried out to determine the effects of different levels of lysine and protein on the performance of 240 Hy-Line W36 layers. Ten experimental diets were tested in a 2×5 factorial arrangement with a completely randomized design. Two basal diets (13 and 14% protein) were tested at different levels (10 and 20% lower than NRC, NRC and 10 and 20% above NRC recommendations). Dietary...

Adequate quality and quantity of athletes’ competition day diet is critically important for better performance and optimum recovery. The aim of this study was to evaluate the adequacy of nutrient intake and dietary practices of Sri Lankan national volleyball players during a day of a major competition. Dietary practices of 76 athletes (43 males and 33 females) were surveyed using 24-hour diet...
The effect of dietary protein level and feed restriction on performance, body temperature and hematological values was evaluated, using Ross 308 broiler chicks under heat stress. For this purpose, three dietary treatments were fed to broilers during 21 to 42 days of age. Two treatments consisted of diets with protein levels recommended by NRC, 1994 and 85% of NRC recommendation and were fed ad-...
The study was conducted with a completely randomized design consisting of four treatments in triplicates. Experimental diets were formulated to contain four different lipid levels (8, 10, 12 and 14%) at constant protein level (46.8%) and different gross energy of 4314, 4417, 4519 and 4622kcal/kg, respectively. Kutum fry (average weight, 203±4mg) were randomly assigned and distributed at a densi...

An experiment was carried out to evaluate how interactions between forage to concentrate ratio and dietary crude protein level may alter nitrogen efficiency and UT-B expression in growing Baluchi male lambs. Four Baluchi male lambs [30 ± 2 kg BW] were used in a 4 × 4 latin square design with 28-d periods and a 2 × 2 factorial arrangement of dietary treatments. The treatments fed forage: concent...

1. The deposition of fat and protein and the utilization of energy by growing rats offered diets ad lib. or in controlled amounts by gastric intubation has been investigated. Diets contained 50, 75, 100 or 200 g protein/kg, mainly as casein. 2. Gain of body-weight and protein increased with increasing dietary protein concentration when animals received the same energy intake, although the rever...
