Several studies have reported data on comparisons between two methods: the total collection of feces and the internal markers method. The aim of this study was to assess the apparent digestibility of two concentrates and to compare the apparent digestion coefficients using the total collection of feces and acid-insoluble ash (AIA) as the internal marker method. In 2009, six adult geldings aged ...

Defined mixtures of two grass (orchardgrass, perennial ryegrass) and two legume (alfalfa, red clover) hays, harvested in two cuttings in 2 yr, were fed in digestibility, intake and mineral balance trials to wether lambs. Each mixture was fed in ad libitum amounts to six crossbred wether lambs weighing 35 to 45 kg. The effect of increasing proportion of legume in mixtures on dry matter digestibi...

The objective of this study was to investigate the effects of diets containing different levels of milk thistle (0, 100 and 200 g/kg dry matter) and grains (barley and corn) with different rumen degradation rates on rumen bacteria and whole rumen microorganisms (WRM) of Khuzestan buffalo. The gas production (GP) technique, two steps digestion and specific bacteria culture medium methods were us...

abstract             the aim of this study was to evaluate the effect of ajowan essential oils (aeo) on rumen fermentation using in vitro gas production. therefore, different doses of aeo (i.e., 0, 150, 300, 450 or 600 ppm) were added to the syringes of the gas production. a typical diet of growing lambs was used as fermentation substrate.  at the first step, the gas production syringes were in...

This study aimed to the digestibility quality of Elephant Grass (Pennisetum purpureum) and concentrate with addition urea molasses in vitro. The was conducted vitro using an experimental method. design used a completely randomized (CRD) four treatments five repetitions: T0 (Elephant 100%), T1 60% + 40% Concentrate), T2 60%) % Umos 40%) T3 Concentrate 20% 20%). results showed no effect (P>0.0...

The influences of pelleting and 13-glucanase supplementation on the digestibility of dietary components in a barley-based diet were investigated in pigs fitted with cannulas in the terminal ileum. The diet contained 49.0% starch, 18.9% crude protein and 14.8% dietary fiber, with arabinoxylans (4.9%), mixed-linked ~-glucans (3.4%) and cellulose (3.3%) as the main fiber components. Pelleting incr...

OBJECTIVE This experiment was to determine proper physical traits in the diet for goats by investigating the effects of physically effective neutral detergent fiber (peNDF) content on dry matter intake (DMI), digestibility, and chewing activity in black goats fed with total mixed ration (TMR). METHODS Six growing wethers of Korean native black goats (Capra hircus coreanae) aged 8 months and w...

quality of protein fractions, according to cornell net carbohydrate and protein system (cncps), and digestibility coefficients, using tilley and terry procedure, of the fresh and ensiled amaranth (amaranthus hypochondriacus) forage were assessed. the concentration of crude protein (cp) and true protein (tp) in the fresh forage, were respectively 116 and 70 g/kg of dm. soluble protein (sp) and a...
