This trial was conducted to determine the extent of prececal starch digestibility depending on the botanical origin of starch and on diet characteristics (i.e., composition and feeding pattern). The prececal disappearance of six substrates (oats, barley, corn, horse bean, potato, and wheat) was measured in four cannulated horses fed (as-fed basis) 11.8 g/kg BW of a high-fiber (HF) or high-starc...

the aims of the present study was to evaluate the level of aflatoxin b1 (afb1) in feedstuffs (corn silage, corn, dried alfalfa, cottonseed meal, cottonseed, soybean meal, canola meal, barley, wheat bran, concentrate, sugar beet pulp and wheat straw) that collected from dairy herds in khorasan razavi province that classified according to milk yield in very high (>10000 kg/day), high (5000-10000 ...

This study aims at investigating the effectiveness of utilizing barley as a Flushing ration with an energizing source and soybean meal-based diets as a Flushing ration with a protein source the sexual and breeding behaviors in Ghezel sheep. To this end, 36 three and half-year old ewes (51±1.5 kilograms) with the record of giving birth to two lambs and 6 three-year old (89±2.5 kilograms) rams we...

The present study was aimed to investigate the effects of supplemental β-mannanase on in vitro ileal disappearance (IVID) and total tract (IVTTD) dry matter (DM) barley, canola meal, copra corn, corn distillers dried grains with solubles, cottonseed palm kernel soybean wheat for pigs. Feed ingredient samples were finely ground divided into control group treatment group. prepared contain 990 g/k...

The objective of this study was to estimate the protein degradability parameters of 6 common ruminant feedstuff using the nylon bags (in situ) and the innovative in vitro method-the DaisyII incubator. Significant differences were observed between the in situ and in vitro methods in estimation of the rapidly soluble (a) fraction (Pin vitro method were highly correlated with the estimated values ...

Two studies were conducted to determine the effect of diets containing low-phytate barley or supplemented with phytase on P balance and excretion in grower pigs. In Exp. 1, eight 32-kg barrows were assigned to a repeated, 4 x 4 Latin square design and fed 4 diets that contained 96% barley: normal-phytate hulled barley (HB), low-phytate hulled barley (LPHB), normal-phytate hull-less barley (HLB)...

The main objective of the thesis was to study AA supply of dairy cows fed grass silage based diets with specific emphasis on the impact of changing individual and total AA supplies arising from individual AA supplementations or changes in the diet on milk production and AA utilisation. Mammary AA metabolism was also studied to broaden the understanding of the mechanisms underlying altered lacta...

Prebiotic compounds, such as short-chain fructooligosaccharides (scFOS), have been shown to improve health, welfare, or both, in several species, but few studies have been conducted in horses, despite the sensitivity of their hindgut microflora. We hypothesized that prebiotic oligosaccharides, known to be able to stabilize the intestinal microflora in other species, would be of importance in ho...
