Effects of synchronizing the availability of amino acids and glucose within a day on protein and energy metabolism were studied in heavy preruminant calves. Thirty-six preruminant calves (148 +/- 1.6 kg body weight) were assigned to 1 of 6 degrees of nutrient synchrony (SYN, 1-6) and to 1 of 2 meal sequences (i.e., the high-protein meal in the morning or in the evening). Calves at SYN 1 receive...

Narasin is an antibacterial agent that may change rumen fermentation. Two experiments were proposed to evaluate the efficiency of narasin inclusion for lambs fed a diet containing high amounts ground flint corn. Thirty rumen-cannulated wethers used nutrient digestibility, nitrogen balance, and metabolism (Exp. 1); forty-five performance 2) animals with corn diets. The experimental diets were: c...

Male broilers (n = 416) were used to compare the efficacy of providing dietary phytase either as a commercial supplement or as a recombinant protein in transformed soybean. From 7 to 21 d of age, broilers were fed a basal diet containing 0.20% nonphytate P (nP) with additional supplementation by fungal phytase as Natuphos or as raw transformed soybeans expressing recombinant phytase at 400, 800...

Forty-eight crossbred weaner pigs divided into three groups of sixteen pigs each were used to assess the effect of feeding frequency on the performance and nutrient digestibility. The same type and quantity of feed was rationed once, twice and thrice daily. Performance of pigs fed twice daily was better than those fed once per day. Digestibility of dry matter, crude protein and crude fibre incr...

Soy lecithin (SL) is a source of phospholipids, which play crucial role in determining cell membrane structure, fluidity, and functionality. This study investigated the effects dietary SL on performance, nutrient digestibility, body composition Nile tilapia juveniles (average initial weight 12.2 g) raised at 22 °C. The experimental diets contained increasing levels (0.0, 21.0, 43.0, 64.0 g kg−1...
