the objective of this study was to determine the effect of irradiation of pomegranate seed (ps) on chemical composition, digestibility and kinetic of gas production. pomegranate seeds were exposed to gamma ray (gr) and electron beam (eb) at doses of 5, 10, 15 and 20 kgy. three ruminally fistulated rams were used for obtaining ruminal fluid for in vitro digestibility and gas production measuremen...

The acid detergent lignin and Klason lignin methods were compared for their correlation with forage digestibility. Thirty-six forages, including C3 legumes and C3 and C4 grasses, were analyzed for sulfuric acid detergent lignin, Klason lignin, and in vitro digestibilities of dry matter (DM) and neutral detergent fiber (NDF). Twenty of these forages were also fed to lambs at restricted intake fo...

Chews are an important part of the pet product industry, with many having potential to decrease plaque or calculus formation. However, their digestion characteristics and gut transit time are virtually unknown. Two experiments were conducted to determine in vitro DM digestibility of expanded pork skin chews and rawhide chews, and apparent total tract digestibility (ATTD), gastrointestinal trans...

________________________________________________________________________________ Abstract Yield, chemical composition, in vitro digestibility and kinetics of fermentation of straw from 18 varieties of oats (Avena sativa L.) were studied. All the straw varieties were grown in three replicates under the same agronomic conditions. Significance differences were observed in the yield of straw (4.4 t...

The nutritive values of non-processed and processed pistachio peel with Neurospora sitophila were evaluated. The chemical composition of samples was evaluated by laboratory analysis. An in vitro digestibility study was done to determine digestibility coefficients of dry matter (DM), organic matter (OM). Digestible organic matter in the dry matter (DOMD) to estimate the metabolizable energy (ME)...

<p>The green macroalgae <em>Ulva lactuca</em> (L.) is a potential alternative protein source. This study investigates the effect of soaking and different drying methods on color quality <em>U. lactuca</em>. Moisture ash content, color, i.e., crude protein, in vitro digestibility, solubility seaweed were determined. In its conduct, fresh was soaked water for various...

Animal by-product meals have large variability in crude protein (CP) content and digestibility. In vivo digestibility procedures are precise but laborious, and in vitro methods could be an alternative to evaluate and classify these ingredients. The present study reports prediction equations to estimate the CP digestibility of meat and bone meal (MBM) and poultry by-product meal (PM) using the p...

The method of Boisen and Fernandez [Boisen, S., Fernandez, J.A., 1997. Prediction of total tract digestibility of energy in feedstuffs and pig diets by in vitro analyses, Anim. Feed Sci. Technol. 68, 277–286] for measuring in vitro fecal digestibility of organic matter (OMdv) or in vitro digestible organic matter content (DOMv, g/kg) was used on 113 compound feeds (79 as mash and 34 as pellets)...

1. Dry matter and crude protein (nitrogen x 6.25) digestibility of four poultry diets determined by an in vitro method using the intestinal fluid of pigs was significantly correlated with corresponding in vivo digestibility values obtained with hens. 2. The intestinal fluid could be lyophilized and stored for at least 35 d without losing its activity on digestion.

The present study evaluated the effects of different cutting height on nutritive value, fermentation quality, in vitro and in vivo digestibility of whole crop barley silage. Whole crop barley forage (Yuyeon hybrid) was harvested at height of 5, 10, and 15 cm from the ground level. Each cutting height was rolled to make round bale and ensiled for 100 days. After 100 days of ensiling, pH of silag...
