Chicory (Chicorum intybus) is becoming popular as a warm-season forage for ruminant livestock in the United States. A study was conducted with weaned crossbred meat goats to elucidate how growing / finishing meat goats grazing Joy chicory pasture respond to supplementation with varying levels of dietary protein. Thirty 6 weaned crossbred kids (26 ± 3 kg) were blocked by body weight and genotype...

The aim of this experiment was to determine the effects of conjugated linoleic acid (CLA) on milk production and composition, and milk fatty acid profile of dairy Holstein cows. Three lactating Holstein cows (203 ± 9 DIM; mean ± SD) fitted with rumen fistula were used in a 3 × 3 Latin square experiment with 21-d periods, including a 14-d adaptation period followed by a 7-d sampling period. Trea...

ferent among treatments. Protozoal counts were not different among treatments (P > 0.05) in ruminal or omasal samples. Generic protozoal counts were not different (P > 0.05) among treatments, corresponding with similar banding profiles from DGGE. Multivariate statistics showed no difference (P > 0.05) in generic distribution of protozoa in ruminal vs. omasal samples, supporting absence of selec...

An epidemiological survey was undertaken from March to September 2010 to assess the prevalence and zoonotic aspects of scabies in small ruminants in two agro-ecological zones in southern Benin. Small ruminant (n = 444) smallholders and 1,807 of their animals (1,233 West African dwarf goats and 574 West African dwarf sheep) were included in the study. The animals underwent physical examination a...

The catabolism of branched-chain amino acid (BCAA) differs between sheep and monogastric animals. The transamination of BCAA seems to be affected by development of the sheep. We studied the developmental changes in the activity and expression of the BCAA aminotransferase (BCAT) isoenzymes in skeletal muscle of sheep. Five muscles were taken from fetus, newborn, preruminant and ruminant lambs. B...

We evaluated the efficacy, sensitivity, host-specificity, and spatial/temporal dynamics of human- and ruminant-specific 16S rRNA gene Bacteroidetes markers used to assess the sources of fecal pollution in a fecally impacted watershed. Phylogenetic analyses of 1271 fecal and environmental 16S rRNA gene clones were also performed to study the diversity of Bacteroidetes in this watershed. The host...

The epidemic of bovine spongiform encephalopathy (BSE) in Europe in the late Twentieth Century required the interplay of two sets of factors, which now provide reference points for assessment of the BSE risk throughout the world. One set of factors consisted of the presence of infective agent in cattle or some other ruminant. The second set consisted of transmission and amplification of the dis...
