Environmental stressors have, over generations, influenced the morphology, anatomy, behaviour, physiology, and genetic structure of small ruminants. The widespread dispersal ruminants vast geographical areas occurred along with human migration, thereby promoting adaptative process to different environmental conditions mainly through natural selection. Ongoing global warming prompted scientific ...

In this paper, an experimental scheme based on poultry manure as a feed additive for ruminants along with compound herbal medicine bacterial inhibitor of was proposed by implementing linear simulations polynomial cubic fitting method today's topical environmental pollution issues chicken and straw. The results the yielded that addition at 1% best ratio value to effectively inhibit bacteria prom...

Comparative physiology applies methods established in domestic animal science to a wider variety of species. This can lead to improved insight into evolutionary adaptations of domestic animals, by putting domestic species into a broader context. Examples include the variety of responses to seasonally fluctuating environments, different adaptations to heat and drought, and in particular adaptati...

Herbivores that digest plant material in the fore-stomach can be divided in ruminants and non-ruminants. This study describes the distribution of feed particles (and inorganic material) and dry matter (DM) in the digestive tract of non-ruminant foregut fermenters. Results from passage trials led us to hypothesize that specific particle-sorting mechanisms, as observed in ruminants, are unlikely ...

Developing production systems for ruminants using tropical feed resources requires an understanding of the relative roles and nutrient needs of the two-compartment system represented by the symbiotic relationship between rumen micro-organisms and the host animal. Fibre-rich, low-protein forages and crop residues are the most abundant and appropriate feeds for ruminants in the tropics. Strategie...

Treatment with urea, feeding of multi-nutritional blocks and high-offer level feeding are the interventions most likely to increase the potential nutritive value of fibrous crop residues. The exploitation of this potential will be determined by the level of supplementation with "bypass" nutrients, especially protein. The optimum level of supplementation will depend on the cost of the supplement...
