Published data on the effects of essential oils (EO) on in vivo nutrient digestibility in sheep are contradictory. In 2 experiments, the effect of thymol and carvacrol on nutrient digestibility was studied in sheep fed with high (70%) or low (52%) concentrate diets, using incomplete Latin Square designs. The essential oils were mixed with the concentrate portion of the diet at the rate of 0.0, ...

Near infrared reflectance spectroscopy (NIRS) provides an opportunity to measure cowspecific organic matter digestibility (OMD) from fecal samples. In this study individual digestibility measurements from a trial with 47 cows were investigated. Digestibility increased when lactation progressed. The repeatability estimates between different lactation stages were low which suggests that several f...

Hetero-yellow (Hu red (RED) and brown (BR, high tannin) sorghums were fed dry-rolled or reconstituted (RED and BR only) to evaluate the effect of variety and reconstitution on the site and extent of starch and protein digestion in steers fitted with ruminal, duodenal and ileal cannulae. Processed grains were incorporated into 88% sorghum (DM basis) diets fed at 2% of body weight in a 5 • 5 Lati...

A total of 360 1-d-old broiler chickens were fed on a diet based on rye and wheat in equal proportions without or with supplementation of increasing levels (0.11, 0.22, 0.44 and 0.88 g/kg) of a technical enzyme preparation containing pentosanase and beta-glucanase activities. In vitro investigations revealed that the enzyme preparation solubilized pentosans, increasing the relative viscosity of...

17-79 ABSTRACT Cumulative gas production from incubation of feedstuffs with rumen liquor or a fresh faecal suspension as inoculum in vitro together with crude nutrient composition can be used to predict organic matter digestibility and metabolizable energy content of ruminant feeds with high accuracy. In this study, prediction equations were derived for roughages using 110 samples with known in...

BACKGROUND Environmental as well as cultivation factors may greatly influence the chemical composition of plants. The main factors affecting the chemical composition of foodstuff are level and type of fertilizer (conventional and organic cultivation systems), location or soil type, and year of harvest. Organic foods are defined as products that are produced under controlled cultivation conditio...

Energy digestibility in the growing pig increases with BW increase and may differ between breeds of pigs or between lines selected on criteria other than digestion. However, little is known about the variability in energy digestibility within a line or a breed of pigs, especially when fibrous diets are fed. For this purpose, 20 Large White castrated male growing pigs originating from four boars...

The study was carried out to find out the differences in the chemical composition of wheat straw obtained from three different regions of India, to compare their susceptibility to fungal degradation, and subsequently to evaluate the correlation between lignin loss and improvement in in vitro digestibility. Four Phlebia species were used to degrade different wheat straw samples during 30 days of...

The aim of the present study was to evaluate the effects of canola bioactive peptides (CBP) produced by enzymatic hydrolysis of canola meal on performance, digestive enzyme activity, nutrient digestibility, gut microflora and intestinal morphology of broiler chickens. A total of 250 one-day-old Ross 308 male broiler chicks were randomly allocated to 5 dietary treatments with 5 replicates of 10 ...
