Ruminant nutrition.
This study investigates the effect of supplementing bovine follicular fluids (FF) to rabbit sperm motility, acrosome reaction and transaminases activities. Ovarian FF were collected from 46 pairs of bovine ovaries. Normal follicles were classified, according to their diameters, into small (SFF, ≤4 mm), medium (MFF,>4-8 mm), large (LFF,> 8 mm) and cystic (CSTFF,>20 mm). Rabbit semen was collecte...
متن کاملFolic Acid in Ruminant Nutrition
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...
متن کاملMathematical Models in Ruminant Nutrition
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...

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...
متن کاملRuminant Nutrition: Ruminal Metabolism
Cultivation of algae for biofuel would result in the production of significant amounts of post-extraction algal residue (PEAR). The economic viability of algae as source of biofuel is dependent on deriving value from PEAR. Livestock feed is an attractive option for PEAR because of the successful utilization of other co-products by ruminants. While sufficient quantities of PEAR were not availabl...
