The ruminal microbiome in herbivores plays a dominant role in the digestion of lignocellulose and has potential to improve animal productivity. Kankrej cattle, a popular native breed of the Indian subcontinent, were used to investigate the effect of different dietary treatments on the bacterial diversity in ruminal fractions using different primer pairs. Two groups of four cows were assigned to...

Using a defaunating method which preserved bacteria and fungi in the rumen, the effect of protozoa on protein and fibre digestion was studied in six adult wethers in relation to the nature of the diet. Sheep were given daily, 42 g dry matter (DM)/kg metabolic body-weight (W0.75), one of two isonitrogenous diets: one contained ammonia-treated wheat straw as the only energy source (diet S) and th...

There is sufficient evidence that ileal rather than fecal amino acid digestibility values provide a more reliable estimate of protein digestion and amino acid absorption. In addition to differences in ileal amino acid digestibility values between feedstuffs there are large differences in ileal amino acid digestibility values within the same feedstuff. Furthermore, in addition to different proce...

Two trials were conducted to evaluate the influence of malic acid supplementation on ruminal fermentation. In Trial 1, six Holstein steers (300 kg) with ruminal cannulas were used in a crossover design experiment to study the influence of malic acid (MA) on ruminal metabolism during glucose-induced lactic acidosis. Treatments consisted of a 77% steam-flaked barley-based finishing diet supplemen...

The present study aims to examine whether and to what extent the bioaccessibility of the major saffron apocarotenoids, namely crocetin sugar esters (CRTSEs), is affected by the presence of strong water-soluble antioxidants, ingredients of the herbs found in commercial tea blends with saffron. An in vitro digestion model was applied to infusions from these products to investigate the possible ch...

Background: The heavy metal pollutions were accumulated in aquatic animals such as fish. Whereas consumption of canned fish is increased in many countries, contaminated fish meat would make a hazard to food security and public health. In this study, the levels ofiron and chromium were measured in canned fish products in in Khuzestan, Iran, in 2015. Methods: Forty-six of canned fish composite s...

Introduction: Calcium critical limit in pistachio plants is about 1.3 percent of plant dried material; magnesium critical limit in pistachio leaves is about 0.6 percent of plant dried material. To measure calcium and magnesium there are several methods in which three methods of titration and atomic absorption that are more common and used to libraries more in addition to ICP modern method are u...

we sought to determine levels of oral bioaccessibility of hydroxymethylfurfural (hmf) from frequently consumed dried fruits in iran. fifty samples from frequently consumed types of dried fruits were analyzed for moisture, acidity and hmf content before and after in vitro digestion. besides, bioaccessibility of hmf in dried fruits using an in vitro gastrointestinal digestive model and hmf intake...

Total diet sample/Elements/Atomic absorption spectrometry/Element correlation Total diet samples were collected from two urban areas in Japan, Sapporo and Kyoto, during the period from 1967 to 1968. The samples, ashed by dry-ashing and acid-digestion, were analyzed for elements by atomic absorption spectroscopy with the flame and electrothermal atomization. Average daily intake found in the two...

The objectives of this study were to investigate the effect starch and protein interaction on rumen environment, in situ digestion, total-tract digestibility nutrients weaned dairy calves between 8 16 wk age. Sixteen rumen-cannulated randomly divided into 4 dietary treatment groups with fed each treatment. diets had 2 levels [18%, low (LS), or 38%, high (HS)] [16%, (LP), 22%, (HP)] a dry matter...
