A trial involving a 2x2 factorial arrangement of treatments was conducted to evaluate two corn silage hybrids (Agromen, AGN35-A42) and (Bayer, A3663) and concentrate levels (25 and 50%) on animal performance. Twenty-four Holstein x Zebu crossbred steers, averaging 335±30kg of BW, were distributed in six randomized blocks to evaluate intake, digestibility, and performance. Treatments consisted o...

Background: Fat supplementation in ruminants ration often adversely affect dry matter intake (DMI), rumen fermentation and nutrients digestion. Basal diet ingredients is an undeniable determinant of ruminants responses including performance, chewing behaviour and nutrient digestibility to fat supplementation. Objective: Current study was conducted to evaluate the effect of Fish oil (FO) supplem...

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 in situ dry matter (DM) disappearance of corn silages in two maturity stages (milk grain and half milk line) of known in vivo and in vitro digestibility was determined, with the main purpose of comparing digestibility values with the ruminal disappearance at 24 and 48h of incubation. A secondary goal was the description of their ruminal digestion kinetics, from which the effective degradabi...

Polyethylene glycol (PEG 4000), Browse Plus (BP), wood ash (WA) and boiling water were evaluated as tannin deactivation methods on tannins in Acacia nilotica fruits. Twenty four Matebele goats of mean body mass, 38.7 ± 3.12 kg, were used in a digestibility and nitrogen balance trial. A completely randomized design was used, and the initial weight was used as a covariate in data analysis. The go...

Near-infrared reflectance spectroscopy (NIRS) was used to predict the chemical composition, apparent digestibility and digestible nutrients and energy content of commercial extruded compound foods for dogs. Fifty-six foods of known chemical composition and in vivo apparent digestibility were analysed overall and 51 foods were used to predict gross energy digestibility and digestible energy cont...
