Bacterial and protozoal communities and fatty acid profile in the rumen of sheep fed a diet containing added tannins.

A study of rumen microbial community of Baluchi lambs fed a high concentrate diet containing conventional ingredients

Baluchi sheep is the dominant fat-tail breed in Iran. We studied the microbial communities in the rumen of four Baluchi lambs fed a high concentrate conventional diet. Using DNA extracted from the rumen samples, we found the partial ribosomal rRNA of bacterial and archaeal were amplified by polymerase chain reaction (PCR). The amplicons were sequenced using 454 Titanium pyrosequencing and the d...

Effects of a diet containing whole cottonseed on rumen protozoal population and fermentation parameters in sheep

Effect of Supplementing Sheep Diet with Glycyrrhiza glabra and Urtica dioica Powder on Growth Performance, Rumen Bacterial Community and some Blood Biochemical Constituents

In this study, nine male Dallagh sheep (initial weight 35±2 kg) were used in a replicated 3 × 3 latin square design experiment with three treatments and three 21-day periods (14 d adaptation, 7 d collection). Treatments were control (without addition) and two treatment diets containing 10% dry matter Glycyrrhiza glabra (licorice) and Urtica dioica (nettle) powder. The dry matt...

Difference in the nature of tannins on in vitro ruminal methane and volatile fatty acid production and on methanogenic archaea and protozoal populations.

Six plant sources of hydrolyzable tannins (HT) or HT and condensed tannins (CT; designated as HT1, HT2, HT3, HT + CT1, HT + CT2, and HT + CT3) were evaluated to determine their effects in vitro on CH(4) production and on ruminal archaeal and protozoa populations, and to assess potential differences in biological activities between sources containing HT only or HT and CT. Samples HT1, HT2, and H...
