A significant decrease in liveweight gain and in food conversion efficiency of parasitised sheep offered Q3 and Q6 compared to sheep offered Q0, was observed in P1 (P<0.05) but not in P2.
The satiating efficiency of foods.
Of course the food conversion efficiency depends on high-quality diets, and livestock conditions (DeFoliart 1997; Cerritos 2009).
Nonetheless their best physiological performance, in terms of growth rate and food conversion efficiency is at much lower salinity levels, (i.e. from 32 g.l-1 up to 65 g.l-1).
Additional research is needed that focuses on adult fish and that combines laboratory and field studies to better understand all aspects of the bioenergetics (e.g. food conversion efficiency, specific dynamic action, and field activity levels) of LVF and HVF.
Low concentrations of gossypol could stimulate larval growth by increasing food consumption rate, increasing food conversion efficiency, or reducing the metabolic cost of other physiological activities.
Fifth instar larvae fed on 704 had the highest efficiency of conversion of ingested food, and those fed on BC 678 showed the lowest relative growth rate.
Traits of importance might be related to growth, disease resistance, food conversion efficiency, color or taste.
Pig breeding programs have been mainly focused on the improvement of growth rate and production efficiency, such as average daily gain, food conversion ratio, dressing percentage, and lean meat content.
The best method of utilization will differ in various countries, depending on the nutritive value of the cereals and products in question, the efficiency of their conversion by animals into human food, the relative cost of plant and animal products and their acceptability to the consumer, and the nutritive value of the diet of the population, particularly of the low-income groups.
It affects all chemical and biological processes and therefore has a direct effect on important factors such as growth, oxygen demand, food requirements and food conversion efficiency.
