The aim of this study was to determine whether farming leads to changes in gastrointestinal function and nitrogen metabolism in farmed mink (FA), as compared with their wild-living counterparts. Three digestibility and balance trials were carried out. Experiment I was performed in May, and...

Three feeding experiments were conducted to determine the feed intake, apparent digestibility and nitrogen retention of growing goats fed with Tithonia diversifolia and supplemented with rumen fermentable protein (cassava root chips and mulberry leaves) and bypass proteins (banana leaves, jackfruit ...

Three experiments were carried out at the Goat and Rabbit Research Centre and on farms in Bavi, Ha Tay province of North Vietnam. In the first experiment, biomass production of Tithonia diversifolia (Wild Sunflower) and the effect on soil fertility was studied in a complete random plot design with...

A 9-week feeding trial was carried out to determine the effect of increasing dietary palm oil levels on growth, protein utilization efficiency and body composition of African catfish. Seven isonitrogenous and isoenergetic practical diets were formulated to contain 4, 8, 12 or 16% refined, bleached, ...

A 100-day experiment was carried out with 288 fingerlings of pacu, assigned to 36, 100-litre cement containers, 8 per unit, to evaluate the replacement of fish flour by soyabean meal and protein levels in the diets. During the experimental period, average water temperature was 28°C and dissolved...

This study was carried out to compare the responses of rainbow trout and Atlantic salmon to being fed defatted soyabean meal. Two extruded experimental diets containing either low-temperature (LT)-fish meal as the sole protein ingredient or 32% fish meal and 30% soyabean meal, were each fed to...

The retention of dietary protein and the waste generated by S. maximus reared under intensive conditions over an experimental period of 5 months were estimated from nutritional budgets. Turbot, 18 months old, were stocked into each of 4 ponds from 20 April to 26 September 1996. Mean weights and...

A feeding trial was conducted to determine the quantitative lysine requirement of juvenile yellowtail by feeding diets containing 6 levels of smallcap˜L-lysine ranging from 1.05 to 3.05% of dry diet in 0.40% increments. The diets contained 43.1% CP in which 32.6% CP came from brown fish meal, maize ...

Juvenile yellowtail, mean weight 23.3 g, were stocked into 12, 800-litre tanks, at 20 fish/tank, and fed on diets containing 0.57-1.58% smallcap˜L-methionine in increments of 0.2%. Fish were fed to satiation 4 times daily for 30 days and liveweight gain, feed utilisation parameters, hepatosomatic...

A study was carried out for 375 days in the outer Himalayas (29°25′N and 79°35′E) where the agroclimate for the major part of the year is cold and humid. Nine male pashmina (Cheghu) kids, (aged 5-6 months) with mean body weight 11.3±0.5 kg, were randomly assigned to 3 groups of 3 animals each in a...
