Parents often signal their arrival at the nest with provisioning calls, which might reduce mistaken begging and increase the efficiency of feeding, and thereby minimize detection by predators.
Although this study did not include a measure of the efficiency of feeding (nectar consumed per unit time), it did confirm that directional selection on tongue length could potentially occur through an energetic benefit.
Expanding knowledge in this area is important for identifying growth-associated genes, increasing the efficiency of feeding and reducing the cost of fish farming.
Sustain the Fill Level: The efficiency of feeding systems depends a great deal on the parts that are fed into it.
Overall, replacing lactose with sucrose or molasses did not affect weight gain, feed intake, or efficiency of feed utilization.
Efficiency measures include a range of practices such as use of genetics to increase growth rate and efficiency of feed use, and improved reproductive performance and health.
It was concluded that subclinical nematode infection had an adverse effect on feed intake, efficiency of feed utilisation and apparent digestibility.
Moreover, fish density can affect the efficiency of feed utilization; as the number of fish stocked in a pond increases, the amount of feed available to each fish decreases ([Chang 1988]).
Fortification of TMR with fibrolytic enymes increased average daily weight gain by 34.7% and the efficiency of feed utilization by 28%.
This means that, even though the steam mass flow (and, consequently, the feed water mass flow) is reduced and the efficiency of feed pumps is improved, their power increases.
Our findings show that a Na deficiency in the diet (0.8 g/kg) decreases the growth rate of turkeys and reduces the efficiency of feed utilisation.
