Apparent feed digestibility was measured for the last 5 d of study.
Under steady state conditions, feces were collected at 49±5% DM and output was 0.26±0.05 kg DM pig−1 d−1 suggesting an apparent feed DM digestibility of 82.8±2.1%.
The condition factor, apparent feed conversion, survival, and gonadosomatic and hepatosomatic indexes of the females were not influenced (P > 0.05) by the diets.
The effects (p < 0.05) for the means of final weight, weight gain, apparent feed conversion and condition factor were observed for the analysis of productive performance.
Lobsters grew significantly faster (P<0.05) at 18°C (SGR=1.32% BW day−1) than at ambient (1.21% BW day−1), with the extra growth explained by a significantly higher (P<0.05) apparent feed intake.
In Experiment 1, although stocking density and application of feed or fertilization did not affect the growth parameters, survival and apparent feed conversion ratio (P > 0.05) of grey mullet, coefficient of variation at harvest weight (CVhw) and total harvested biomass were influenced by feeding or fertilization (P < 0.05).
The focus of this study was to evaluate the effect of lysine on the productive (weight and length gain, apparent feed conversion, specific growth rate and condition factor) and reproductive performance of Rhamdia voulezi males confined in net cages during the first reproductive cycle.
The apparent feed-forward regulation of NO production may prove to be critical in amplifying the signals necessary for the protection associated with oxidative phenotype.
The decision to withhold feeds or deviate from the feeding schedule in Tables 2 and 3, because of apparent feed intolerance or clinical deterioration, will also remain at the local clinician's discretion.
In a uniform grouping, dominance between various species is apparent in feeding competition, suggesting a definite nipping order.
