Overall, replacing lactose with sucrose or molasses did not affect weight gain, feed intake, or efficiency of feed utilization.
However, the genetic basis of feed utilization in livestock remains poorly understood.
Feed cost constitutes about 70% of the cost of raising broilers, but the efficiency of feed utilization has not kept up the growth potential of today's broilers.
In addition, further studies on the biology associated with feed efficiency would lead to advances in our knowledge about the efficiency of feed utilization by the bovine.
Efficiency of feed utilization is important for animal production because it can reduce greenhouse gas emissions and improve industry profitability.
Benefits of improving the efficiency of feed utilization can be extended by appropriate feeding practices: in laying hens, sequential feeding of wheat grain and protein mineral concentrate improved feed conversion, and could facilitate the use of local feedstuffs introduced as whole grains, thus reducing feeding costs (Faruk et al., 2010).
The results revealed that nutrient utilization was unaffected up to 60% level but it was drastically reduced at 40% level of feed intake.
The present study demonstrated that the dietary additives produced different response levels in terms of growth, feed utilization, immune responses and disease resistance in juvenile Amur catfish.
This study investigated the effect of dietary Zn levels on growth performance, feed utilization, and hematological parameters of juvenile Siberian sturgeon (Acipenser baerii, Brandt 1869).
Accordingly, the aim of the present study was to evaluate the effects of elevated zinc levels on growth performance, feed utilization, and hematological parameters of juvenile Siberian sturgeon (Acipenser baerii, Brandt 1869).
