It is concluded that maize cob inclusion reduces nutrient utilisation in both breeds, although Mukota pigs can utilise high fibre diets better than Large White pigs.
Elderfield, H. & Rickaby, R. E. M. Oceanic Cd/P ratio and nutrient utilisation in the glacial Southern Ocean.
Fish performance was assessed by measuring mortality, feed intake, growth, nutrient digestibility and nutrient utilisation.
Applying an agricultural perspective when evaluating the system highlighted potential conflicts regarding nutrient utilisation.
In conclusion, excess K in the diet depresses growth and nutrient utilisation efficiency, reduces body fat and protein deposition.
In contrast, during the Holocene, nutrient utilisation was less efficient, resulting in a reduction of respired carbon storage at depth, with the consequent transfer of carbon from the deep sea to the atmosphere.
The three primary knowledge sets required are: (i) ingredient digestibilities, (ii) ingredient palatability, and (iii) ingredient nutrient utilisation potential and/or interference of utilisation potential.
The effects of dietary Na/K ratios on feed intake, growth, nutrient utilisation, plasma and body mineral concentration in juvenile African catfish were investigated.
Wilting had no effect on the yield of milk fat or protein but the nutrient utilisation studies suggested that the overall efficiency of metabolisable energy conversion to milk energy output was reduced with increasing degree of wilting.
Gastrointestinal (GI) parasitism is of great importance in sheep and goats production because it results in lowered animal productivity (reduced nutrient utilisation, growth rate, milk and wool production), whereas severe infections can cause animal mortality.
