Two experiments were conducted to evaluate the effects of chemical composition of wheat shorts and red dog on energy and amino acid digestibility in growing pigs and to establish prediction models to estimate their digestible (DE) and metabolizable (ME) energy content and as well as their standardized ileal digestible (SID) amino acid content. For Exp. 1, sixteen diets were fed to thirty-two gr...

iranian farmers are faced with many challenges. they must be economically efficient, produce enough food for the growing population and must be sensitive to environmental concerns. however, there is a growing concern related to the aftermath and side-effect of some agricultural activities on environment. these concerns made researches to consider agricultural activities with profound care in or...

We reported previously that the pellagragenic property of corn protein is not only low l-tryptophan concentration but also the lower conversion percentage of l-tryptophan to nicotinamide; the amino acid composition greatly affected the conversion percentage. The amino acid value of wheat protein is lower than that of rice protein. In the present study, we compare the conversion percentages of l...

The effect of feeding nutritionally different diets in sequential or loose-mix systems on the performance of laying hen was investigated from 16 to 46 wk of age. Equal proportions of whole wheat grain and protein-mineral concentrate (balancer diet) were fed either alternatively (sequential) or together (loose-mix) to ISA Brown hens. The control was fed a complete layer diet conventionally. Each...

Himalaya 292 (Hordeum vulgare, var. himalaya 292) is a novel, hull-less barley cultivar with a single nucleotide change in the gene encoding starch synthase IIa (EC 2.4.1.21). This leads to loss of enzyme activity, resulting in a grain with less total starch and a higher proportion of amylose. These changes, plus higher total and soluble nonstarch polysaccharides (NSP), could increase its resis...

The utilizable energy content of wheat distillers dried grains with solubles (wheat-DDGS) without or with supplementation of enzyme containing xylanase, amylase and protease (XAP) activities was deter­ mined for turkeys using linear regression method. A total of 126 BUT 10 male turkeys were fed a nutrient-adequate starter diet from d 1 to 14. On d 14, the birds were assigned to 6 dietary treatm...

Male albino rats were fed on respective diets of wheat flour, Bengal gram flour and corn flour for 8 weeks at the 59% level. It was observed that the increase in weight after wheat flour and Bengal gram flour feeding was 6.8 and 12.0% respectively and that the decrease after corn flour feeding was 5.2% as compared to the control animals on sucrose diet. Serum cholesterol and liver cholesterol l...

The aims of the investigation were to compare calculation methods for ileal apparent digestibility (AD) of amino acids (AA) and to demonstrate the calculation of ileal true digestibility (TD) using the regression approach and additionally, to compare the TD with the standardized digestibility (SD). Eight Goettingen minipigs, average 52 kg initial BW, were fitted with ileo-rectal anastomoses and...

Feeding experiments were conducted to determine whether wheat could metabolize exogenously added trichothecenes. Middle spikelets of a moderately resistant wheat cultivar Su8060 were fed in triplicate, on ten sets of plants, with a fixed amount of deoxynivalenol (DON, 4000 ng). One day after adding DON, the treated spike on one set of plants and adjacent tissue was removed for toxin analysis us...
