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 کاملRuminant Nutrition Symposium: Improving cell wall digestion and animal performance with fibrolytic enzymes.
This paper aimed to summarize published responses to treatment of cattle diets with exogenous fibrolytic enzymes (EFE), to discuss reasons for variable EFE efficacy in animal trials, to recommend strategies for improving enzyme testing and EFE efficacy in ruminant diets, and to identify proteomic differences between effective and ineffective EFE. A meta-analysis of 20 dairy cow studies with 30 ...
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...
متن کاملRuminant Nutrition: Dairy Cattle
Replacing dietary starch with sugar and sodium-propionate has been reported to improve performance in ruminant animals. This experiment was conducted to determine the effects of replacing different sources of energy with barley grain in dairy calves′ starter on weaning, dry matter intake, average daily gain (ADG), feed efficiency, skeletal growth, and fecal score. A total of 21 male calves (42 ...
