The absorption of peptides by the ruminant gastrointestinal tract is an important physiological process. The breakdown of proteins by m e n microorganisms gives rise to peptides, and recent observations suggest that these peptides make a significant contribution to non-ammonia nitrogen flow to the small intestine, and are available for absorption [I]. In the intestine of non-ruminant species th...

Livestock are an integral part of agriculture that contribute to 35 49% the agricultural GDP, 37 87% household incomes, and 15 17% foreign exchange earnings country. There about 33.02 million heads sheep 38.96 goats’ population in Ethiopia. They important components livestock subsector sources cash income, milk, meat, wool, manure, saving or risk mitigation during crop failures, property securi...

Ruminant species differ in the degree that their rumen contents are stratified but are similar insofar that only very fine particles are passed from the forestomach to the lower digestive tract. We investigated the passage kinetics of fluid and particle markers (2, 10 and 20 mm) in fistulated cattle (Bos primigenius f. taurus), muskoxen (Ovibos moschatus), reindeer (Rangifer tarandus) and moose...

Peste-des-petits-ruminants virus (PPRV) and rinderpest virus (RPV) are two morbilliviruses of economic relevance in African and Asian countries. Although efficient vaccines are available for both diseases, they cannot protect the animals before 14 days post-vaccination. In emergencies, it would be desirable to have efficient therapeutics for virus control. Here, two regions are described in the...

The ruminant is able to digest and utilize a wider range of carbohydrates than most other mammals, yet the means whereby it carries out this digestion also ensures that it may, during periods of high productivity, suffer from a shortage of glucose. Indeed the plight of the high-producing ruminant is not so very different from that of the ancient Mariner who had ‘Water water every where. Nor any...
