A study was designed to collect a database of Iowa feedlot rations for determination of effective neutral detergent fiber (NDF) in complete diets from fiber analysis and particle size determination of individual feed ingredients and compare this with particle size determination of mixed wet rations. Seventy-one beef finishing total mixed rations were collected by ISU Extension Beef Field Specia...

The purpose of the study was to investigate whether dietary ration or diet composition in£uence the relationship between plasma growth hormone (GH) and insulin-like growth factor-1 (IGF-1) in Arctic charr (Salvelinus alpinus L.). The pattern of changes in plasma GH and IGF-1 concentrations was examined in ¢sh fed at di¡erent ration levels (0%, 0.35% and 0.70%BWday ) for 5 weeks, and in ¢sh fed ...

An experiment was conducted to study the effects of feeding growing pigs a diet low in selenium (Se) and vitamin E (E) with and without supplementation of various levels of Se and/or E on tissue Se and serum tocopherol concentrations. Nine of 10 pigs fed the unsupplemented cull pea diet had lesions attributed to a Se-E deficiency and eight of these pigs died during the 135-day experiment. No de...

a feeding trial of 120 days duration was conducted to study the effect of replacing 20 and 25 % of camel ration by poultry litter (pl) on the performance and some blood biochemical parameters. fifteen healthy one–humped camels were allotted into three groups (5 animals / group). the first group was fed a basal ration and considered as control, while the second and third groups were fed rations ...

In a previous report (I) it was demonstrated that chicks receiving purified rations low in nicotinic acid grew poorly and developed a typical chick blacktongue. The occurrence of these symptoms was prevented by the addition of nicotinic acid to the ration. This paper presents further studies on this deficiency and gives data on the activity of several nicotinic acid esters, as well as studies o...
