The kinetics of nutrients digestion and development chyme characteristics in African catfish (Clarias gariepinus) were assessed response to fishmeal hydrolysation non-protein energy (NPE) sources. Four diets formulated contain starch or fat as NPE source, hydrolysed protein source a 2 × factorial design. Juvenile (average weight, 63 g) stocked glass experimental tanks connected common recircula...

The position of fatty acids in the TAG molecule (sn-1, sn-2 and sn-3) determines the physical properties of the fat, which affects its absorption, metabolism and distribution into tissues, which may have implications for the risk of CHD. The TAG structure of fats can be manipulated by the process of interesterification, which is of increasing commercial importance, as it can be used to change t...

Comparative investigations were made between wild and domestic ruminants from arid and semi-arid regions and those species from non-arid areas in an attempt to evaluate the adaptations of these ruminants in terms of the effects of heat stress and dehydration on food intake and digestibility. The effect of (a) an intermittent heat load (a daily light cycle of 12 h at 22 degrees C and 12 h at 40 ...

In this feeding trial, a total of 500 Cobb-500 broiler (day-old) chickens were randomly assigned to control dietary treatment (basal diet only) or supplemented with crushed seeds coriander (Coriandrum sativum L.), black cumin (Bunium persicum (Boiss.) B. Fedtsch) and ajwain (Carum copticum L.) (at 10 mg/kg each) exogenous protease (30,000 IU/kg), respectively, in order assess the effect diets o...

Effects of synchronizing the availability of amino acids and glucose within a day on protein and energy metabolism were studied in heavy preruminant calves. Thirty-six preruminant calves (148 +/- 1.6 kg body weight) were assigned to 1 of 6 degrees of nutrient synchrony (SYN, 1-6) and to 1 of 2 meal sequences (i.e., the high-protein meal in the morning or in the evening). Calves at SYN 1 receive...

The objective of this study was to evaluate the productive performance, apparent digestibility, and carcass longissimus dorsi muscle characteristics lambs fed diets supplemented with four levels Saccharomyces cerevisiae. Thirty-two male Hampshire (25.82±1.95 kg body weight) were distributed in treatments: basal diet (20:80, forage:concentrate), inclusion 0, 3, 5, 10 g animal−1 d−1Saccharomyces ...

An experiment was conducted to evaluate the effects of soybean hulls (SH) containing varying ratios of insoluble:soluble fiber (I:S) on nutrient digestibilities and fecal characteristics of dogs. Ileally cannulated dogs (n = 6) were fed seven diets in a 6 x 7 Youden square arrangement of treatments. The seven diets included five SH-containing diets with I:S of 1.9, 2.7, 3.2, 5.2 or 7.2 and two ...
