Globally, the utilization of alternative protein sources in livestock feed has been extensively deliberated and established to be best novel approach. Extensive research indicated that insects provide good opportunities as a sustainable, high quality, low-cost component animal feed. The use diet sounds prospective opportunity leading sustainability feeds meet intensifying worldwide plea for pro...

Importance of Feed Efficiency The ability to improve the utilization of nutrients has tremendous potential to improve profitability. It has been estimated that a 10% improvement in performance (gain) would increase profit by 18%, while a 10% improvement in efficiency could improve profit by upwards of 43%. It has also been estimated that a 10% improvement in feed efficiency (assumed to be a 2 l...

A 84 day experiment was conducted to evaluate the effect of sodium diformate NDF ® as commercial feed additives on growth performance and feed utilization of hybrid tilapia (♀ O. niloticus X ♂ O. aureus) fingerlings. Four treatments were applied; three levels of NDF ® (1 g kg -1 , 3 g kg -1 and 5 g kg -1 ) in addition to the control. The experimental diets containing (320 g kg -1 crude protein ...

The current study was undertaken to estimate variance components for phytate P bioavailability (PBA) and the genetic correlations among PBA with growth and feed utilization (or intake) traits in an unselected random mating chicken population. Pedigreed data from 901 Athens-Canadian randombred chickens hatched from 26 sires, 71 dams, and 105 grandparents were used for estimation of genetic param...

Twenty "Red Danish" bulls were tested for rate of gain, linear growth, longissimus muscle area and efficiency of feed utilization from the age of l 'h to 12 months. These variables were correlated to blood concentrations of testosterone and somatomedin, which were measured at 4 to 5 months, 6 to 7 months and/or 8 to 10 months of age. Average testosterone concentrations of bulls above 6 months o...

Current interest in amaranth as a food resource for humans and animals has been stimulated by activities in germplasm collection and testing in the U.S. Fifteen growing, intact male lambs weighing 18.7 kg were assigned randomly to three diets (five lambs/diet) for a 14-d growth trial followed immediately by an 8-d (4-d adjustment, 4-d collection) digestion and N balance trial to determine the u...
