The aim of the study was to evaluate the supplementation of active yeast (Saccharomyces cerevisiae) on diets of lambs fed with two different concentrate proportion on DM intake, apparent digestibility of nutrients, in vitro digestibility of dry matter and rumen fermentation parameters. Twenty non-castrated male lambs, averaging 120 days-old, housed in metabolism cages, with collector and separa...

AIM The aim of the current study was to protect the protein in mustard cake by different levels of formaldehyde treatment with a view to optimize the level of formaldehyde. MATERIALS AND METHODS Different levels of formaldehyde treatment (0, 1, 1.5 and 2% of crude protein) containing concentrate and roughages diet in 40:60 ratio were tested for their effect on nutrients digestibility, in vitr...

Sixteen rams (mean age: 13 mo; mean live weight: 40.0 ± 2.4 kg) were randomly allotted to four dietary treatments in a completely randomized design (4 rams per treatment). Diets (dry matter basis) contained 65% concentrate and 35% alfalfa hay (control diet, T1), 35% wheat straw (T2), 35% barley straw (T3) or 35% maize straw (T4). Total-tract apparent digestibility for dry matter, organic matter...

Seed samples from two near-isogenic faba bean (Vicia faba L.) lines were examined for the levels of so-called anti-nutritional factors (ANF). From the ANF known to be present in faba beans, trypsin inhibitor activity, functional lectins, condensed tannins and pyrimidine glycosides were analysed. It was concluded that the lines differed only in the content of condensed tannins being < 0.5 g/kg a...

TWO methods of estimating pasture intake from total faecal output are discussed. Dry matter indigestibility co-efficients (apparent) are useful where the range of inter-species digestibility is relatively narrow in any one seasonal period. A relationship between total faecal nitrogen excretion and dry matter intake is illustrated and the biological principles upon which this type of relationshi...

Supplementation increased the total dry matter intake by 18.2-36.8 %. Supplements given alone or in combination had no effect on dry matter and organic matter digestibility of the diet. Crude protein digestibility was decreased with molasses supplementation. Crude fiber digestibility was not affected by baker’s yeast supplementation but decreased with other supplements. The digestibility of nit...

to study the chemical composition and qualitative comparison of the pistachio by-products and the effect of pistachio hull tannin on its digestibility and gas production, four experiments were carried out. in the first experiment, nutrient composition, phenolic and tannin components of the ohadi, kaleghuchi and white varieties of pistachio by-product from dehulling process were measured. pistac...

The effect of inclusion of garlic essential oil (EO) at 33, 66 and 100 μg mL-1, raw garlic (GAR) at 5, 10 and 15 mg mL-1 and monensin (MON) at 7.5 μg mL-1 of incubation medium on organic matter digestibility (OMD) was studied with in vitro gas production, ANKOM daisyII and conventional in vitro (IVOMD) methods. The material was incubated with sheep ruminal fluid and the experimental design was ...

This study evaluated the digestibility of leguminous protein labeled with 15N, by using nitrogen balance and quantitation of fecal endogenous nitrogen (FEN), determined by isotopic dilution, in order to correct apparent values. Seeds of common beans, cowpea and common pea labeled with 1.000 atoms% of 15N-excess were used as protein sources in diets for 60 male Wistar rats, during a 6-day assay....
