The gastrointestinal (GI) habitat of ruminant and non-ruminant animals sustains a vast ensemble of microbes that are capable of utilizing lignocellulosic plant biomass. In this study, an indigenous swine (Zovawk) and a domesticated goat (Black Bengal) were investigated to isolate bacteria having plant biomass degrading enzymes. After screening and enzymatic quantification of eighty-one obtained...

The objective of this work was to evaluate hematological, biochemical and ruminant parameters for diagnosis and treatment of the left displaced abomasum (LDA) in dairy cows, in the Plateau Region of Rio Grande do Sul, Brazil. Ruminant fluid, blood and urine samples were collected from 20 cows suffering LDA and from 20 healthy cows (control). The cows with LDA showed lower values of daily milk p...

1. A method for gas-liquid chromatographic analysis of the dimethyl esters of a homologous series of diabolic acids is described. 2. Only when combined with low-resolution mass spectrometry could the method be used to show unequivocally the existence of diabolic acids in natural products. 3. Diabolic acids occurred naturally in rumen and faecal lipids of all ruminants examined but could not be ...

Advances in our understanding of lipid metabolism in the ruminant and the effect of specific fatty acids on both ruminant metabolism and human health has increased significantly in recent years. Unique biohydrogenation intermediates formed in the rumen have been shown to be potent inhibitors of milk fat synthesis, and the biology behind this and its potential application and benefit to both ani...

during the course of further work to be reported at a later date. It is certain that there are differences in the effect of diet on different tissues as Long (1953) has found that, although the hexokinase activity of intestinal mucosa is depressed by a lowcarbohydrate diet, that of intestinal muscle is unaffected. In so far as attempts to reproduce the anomalies of carbohydrate metabolism obser...

Cultivation of algae for biofuel would result in the production of significant amounts of post-extraction algal residue (PEAR). The economic viability of algae as source of biofuel is dependent on deriving value from PEAR. Livestock feed is an attractive option for PEAR because of the successful utilization of other co-products by ruminants. While sufficient quantities of PEAR were not availabl...

Replacing dietary starch with sugar and sodium-propionate has been reported to improve performance in ruminant animals. This experiment was conducted to determine the effects of replacing different sources of energy with barley grain in dairy calves′ starter on weaning, dry matter intake, average daily gain (ADG), feed efficiency, skeletal growth, and fecal score. A total of 21 male calves (42 ...

An experiment was performed with the objective of evaluating the performance of beef steers on diets consisting of increasing levels of corn milling by-products (BP) (50% wet corn gluten feed, 50%wet distillers grains; DM basis) and different alfalfa hay levels. 280 yearling steers (370 kg BW) were blocked (3 blocks) by weight, stratified within block and assigned to 35 pens (8 steers/pen). Pen...
