The purpose of this study was to determine the comparative efficacy of locally-produced yeast to commercial yeast on growth performance, serum biomarkers, and gut histology. Thirty pre-weaned male Lohi lambs were divided into; 1) C (Control; starter diet with no…
Lupin is considered a potentially rich source of energy and protein for various livestock breeds. However, there are no studies on rumen fermentation and meat composition of Hanwoo (Korean native) steers following supplementation with lupin flakes. In vitro and in…
The research aimed at assessing the effects on nutrient digestion and ruminal fermentation by goats of a complete feed block (CFB) that incorporated agro-industrial by-products that were high in fibre and cellulolytic bacteria. Three Kacang goats, a native Indonesian breed,…
Ruminant utilization of poor-quality feeds is governed by rates of digestion and of passage through the rumen. The passage rate of feed material determines the quantity of bypass nutrients and the efficiency of synthesis of microbial protein in the rumen,…
A study was conducted, first, to compare the gastrointestinal tract (GIT), reticulo-rumens and intestinal capacities (relative to body weight) of ram lambs from six Turkish sheep breeds: Turkish Merino (TM, Anatolia Merino), Akkaraman (AK), Kıvırcık (KV), Awassi (AW), Karayaka (KY)…
The objective of this study was to evaluate the effects of slow-release α-amylase in ruminal in vitro digestion of maize and sorghum grains. Digestibility was measured using an in vitro procedure with 40 mL of buffer and 10 mL of…

Leaves of 10 different plant species utilized by the kudu were collected, dried and ground. This material was used to determine DM digestibility, gas production and VFA production during in vitro fermentation with rumen fluid obtained from kudu. Plants preferred…
The rumen degradability of protein in diets containing maize straw, fish meal and 0, 30 and 60% maize grain was estimated in three ways: (i) from the difference between the total non-ammonia N and microbial N entering the duodenum over…
The composition of the ruminal flora and the VFA concentration were surveyed in the water buffalo found in tropical Asia. The results showed that the average concentration of VFA in rumen contents was 57 mM and the number of bacteria…
Experiments were conducted to examine the difference in intake between hay and silage made from lucerne (Medicago sativa) and whether these differences could be accounted for in terms of physical rumen characteristics. Voluntary intake was lowest on lucerne hay ensiled…
An experiment was conducted with eighteen rumen cannulated sheep fed on a chopped lucerne diet. Previous level of intake significantly influenced the level at which sheep initially established voluntary feed intake. This difference had disappeared after three weeks on an…
Volatile fatty acid production was studied in the rumen and caecum of culled grey duiker (Sylvicapra grimmia) and in the rumen of tame fistulated duikers. The caecum had a higher total VFA concentration and production rate per unit volume than…
Although the protein requirement of domestic ruminants may be calculated from a simple one-compartment model, this approach ignores factors such as microbial fermentation in the rumen and the non-equality of feed proteins. By examining digestion in each of the functional…
Five models were studied for goodness of fit to in sacco organic matter disappearance. Except for the first-order model, all the other models showed an accurate and unbiased fit, although in some cases this was achieved by unrealistic parameter estimates…
Fermentation in the rumen, measured by a steady state in vivo method, was compared to in sacco estimates obtained by different methods of calculation. These methods included a first-order model calculated over 24 h, a first-order…
The effect of starch fermentation in the rumen on the kinetics of roughage digestion, was studied using 12 sheep fed three roughages, viz. lucerne hay, maize cob leaves and wheat straw. The amount of starch infused per day was increased…
This study was conducted to assess the effect of greenleaf desmodium (Desmodium intortum) and sweet potato vine (Ipomoea batatus) supplementation of napier grass on dry matter intake, degradation and rumen fermentation in Friesian steers. Four fistulated steers were offered napier…
