Two forms of exertional rhabdomyolysis commonly respond to changes in diet and management. Unfit horses with polysaccharide storage myopathy benefit from daily exercise, removal of high-starch concentrates, and addition of fat to provide a moderate caloric intake. Fit horses with recurrent exertional rhabdomyolysis can maintain a high caloric intake if dietary starch is reduced and the ration i...

Introduction Even though many of the cattle finished in the United States are fed in large feedlots there are still many small finishing operations that lack the equipment and facilities of commercial feedlots and there are individuals that have an interest in fattening their own beef; 4-H projects or locker beef are prime examples. When finishing cattle, the nutritional requirements do not var...

Nitrite poisoning in pigs was suspected when 4 of 18 pigs died in a piggery near Ellisras in the Northern Province. The pigs showed typical brownish discolouration of the blood at autopsy. It was established that they ingested vegetable tops and weeds from the adjacent garden as part of their daily ration. Of the available plants, only Capsella bursa-pastoris contained nitrites. The drinking wa...

Abstract This study aimed to determine the effect of using fermented shrimp shell meal in feed on growth Asian sea bass. was designed with a completely randomized design (CRD) 4 treatments and 3 replications thus treatment obtained A (feed without meal); B (Feed 15% C 20% meal) D 25% meal). Parameters observed were daily rate survival. The results showed that percentage substitution fish ration...

When adult females of Calanus pacificus are fed on monospecific cultures of centric diatoms which grow as single cells, a predictive relationship is found between feeding behavior of the copepods and size and concentration of food particles. Ingestion rate of copepods increases linearly with cell concentration up to a maximal rate. This maximal ingestion rate, expressed as carbon, is the same f...

The hypothesis that infrequent feeding of sheep supports a higher rate of wool growth than frequent (daily) feeding was examined using oats grain and three roughages of varying protein content. The wool growth of Merino ewes fed every third and sixth day was significantly greater than that of similar ewes fed every day, when averaged over the four diets. Increased wool production due to infrequ...

In mammals, neuropeptide Y (NPY) is a potent orexigenic factor. In the present study, third brain ventricle (intracerebroventricular) injection of goldfish NPY (gNPY) caused a dose-dependent increase in food intake in goldfish, and intracerebroventricular administration of NPY Y1-receptor antagonist BIBP-3226 decreased food intake; the actions of gNPY were blocked by simultaneous injection of B...

The objective was to establish effects of feed presentation time and dietary forage to concentrate ratio on circadian postprandial rhythms of feed intake in lactating cows. Four multiparous and four primiparous Holstein cows were fed in a 4 × 4 Latin square design (with a 2 × 2 factorial arrangement of treatments) a higher (HC, forage to concentrate ratio = 38.5:61.5) or a lower (LC, forage to ...
