Ruminant livestock are raised under diverse cultural and environmental production systems around the globe. can play a critical role in food security by supplying high-quality, nutrient-dense with little or no competition for arable land while simultaneously improving soil health through vital returns of organic matter. However, context climate change limited resources, ruminant-based is uncert...

A region is considered self-sustainable when the feed provision is adequate for all livestock demands. Livestock is fed in order to supply nutrient needs for maintenance, growth, and reproduction purposes. This study aimed to determine whether Madura Island inIndonesia is able to independently provide sufficient forage for its ruminant livestock. A Carrying Capacity Index (CCI) in four regions ...

Livestock have made major contribution to human societies by providing food, shelter, fuel, and services.  Sheep and goat are economically important livestock play an important socioeconomic role for small and large farmers in Libya.  Small ruminant animal meat is popular for Libyan customers, and demand is particularly high during religious and cultural festivals.  Small ruminants is valued fo...

Folic acid plays an essential role in ruminant nutrition. Microorganisms in the rumen can synthesise folates, but these amounts are not sufficient to achieve the best efficiency of dairy cows. However, the amount of folates synthesised in the rumen could possibly, to some extent, be affected by the forage: concentrate ratio. The supply of folates by the diet and the synthesis by ruminalmicroflo...

The objective of this experiment was to investigate the effects of lauric and myristic acids on ruminal fermentation, production, and milk fatty acid (FA) profile in lactating dairy cows. The experiment was conducted as a replicated 3 × 3 Latin square. Six ruminally-cannulated cows (95 ± 26.4 DIM), were subjected to the following treatments: 240 g/cow/d of each, stearic (SA, control), lauric (L...

Mathematical models can be used to improve performance, reduce cost of production, and reduce nutrient excretion by accounting for more of the variation in predicting requirements and feed utilization in each unique production situation. Mathematical models can be classified into five or more categories based on their nature and behavior. Determining the appropriate level of aggregation of equa...

Multisystemic disease caused by Small Ruminant Lentiviruses (SRLV) in sheep and goats leads to production losses, to the detriment of animal health and welfare. This, together with the lack of treatments, has triggered interest in exploring different strategies of immunization to control the widely spread SRLV infection and, also, to provide a useful model for HIV vaccines. These strategies inv...

Sci. 13: 357-374 Interest in the use of fungal direct-fed microbials in ruminant nutrition is considerable. The ban of antibiotic growth promoters in feed for production of animal foods has increased interest in evaluating the effec...
