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, ...

The development of the yield and nutritive value of timothy (Phleum pratense L.) both in the primary growth and in the regrowth were studied at MTT Plant Production Research, a unit of MTT Agrifood Research Finland, in Rovaniemi (66°35 ́N) in 1999–2001. The dry matter yield and leaf to stem ratio were measured from the crop samples, and the contents of crude protein and organic matter digestibil...

Estimation of the quality of commercial diets is a topic of interest for the majority of dog owners. Recently, in a French consumer association magazine, an evaluation of eight dog commercial dry diets (from super-premium, basic-nutrition, private-label and economy brands) according to several nutritional criteria was published. The aims of the study were: (1) to evaluate the apparent digestibi...

Male broiler chicks (n=120) were fed diets containing 0, 5, 10 or 15% dried distillers' grains with solubles (DDGS) from the 12th day up to the end of fattening (day 35). During this period feed intake, weight gain and excreta quality (pH, DM) were tested. A digestibility trial was carried out on four birds from each group on the last five days of the experiment to determine the digestibility o...

Eight mature dogs (19.3 +/- 0.1 kg) were used in an experiment to compare the effects of feeding soybeans containing low concentrations of oligosaccharides and phytate on nutrient availability in complete foods fed to dogs. All foods were formulated to be isonitrogenous and contained low-oligosaccharide, low-phytate soybean meal (LLM); conventional soybean meal (SBM); low-oligosaccharide, low-p...

Sorghum prolamins, termed kafirins, are categorized into subgroups α, β, and γ. The kafirins are co-translationally translocated to the endoplasmic reticulum (ER) where they are assembled into discrete protein bodies that tend to be poorly digestible with low functionality in food and feed applications. As a means to address the issues surrounding functionality and digestibility in sorghum, we ...

The purpose of this study was to determine the effect fermented straw supplementation with green concentrate on nutrient content and digestibility. Green used as treatment white lead tree leaf flour ( Leucaena leucocephala ), Gamal meal Gliricidia sepium Indigofera meal. Proximate analysis carried out rice straw, 70% + 30% lamtoro (FRS tree), ) ). livestock for digestibility test 12 Friesian Ho...

Ileal digestibility and availability of lysine in protein concentrates ,for pigs The availability of lysine in protein concentrates for pigs and the relationship between ileal digestibility and availability have been investigated in two separate research projects : Dr Jane Leibholz of the University of Sydney, with weaner pigs, and myself at the Wollongbar Agricultural Institute, using grower p...

The apparent ileal digestibility of amino acids in 7 feed ingredients was determined using broilers, layers, and roosters. The ingredients included 3 cereals (wheat, sorghum, and corn), 3 oilseed meals (canola, cottonseed, and soybean meals), and 1 animal protein meal (meat and bone meal). Dietary protein in the assay diets was supplied solely by the test ingredient. All diets contained 20 g/kg...

Ethanol producers remove lipid from distillers grains (DG) for applications such as biodiesel production. The effects of the lipid removal on ruminal protein degradability and total-tract CP digestibility of DG are not known. Five ruminally and duodenally cannulated Angus-cross steers (BW = 434 ± 15 kg) were used to incubate in situ bags for determination of protein digestibility of low-lipid (...
