Energy metabolism reactions in ruminant muscle: responses to age, nutrition and hormonal status

Ruminant 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...

Ruminant Nutrition: Dairy: Rumen Metabolism

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...

Microwave irradiation of whole soybeans in ruminant nutrition: Protein and carbohydrate metabolism in vitro and in situ

Whole soybeans serve as one of the main sources of protein in ruminant nutrition. Different processing methods have been employed for ruminal protein protection. The present study was conducted to determine the effects of microwave irradiation [900 W; 2, 4 and 6 min] on quality, ruminal degradability and estimated in vitro intestinal digestibility of availability soybean crude protein....
