Effect of increasing ruminal butyrate on portal and hepatic nutrient flux in steers
Article Abstract:
Ruminally cannulated steers fitted with catheters in the mesenteric, portal and hepatic veins and the mesenteric artery were used to determine the effect of ruminal butyrate concentration on the nutrient flux in portal and hepatic circulations. Results showed that increasing the butyrate concentration in the rumen increased its arterial and splanchnic fluxes and decreased the arterial flux of other nutrients, such as amino acids and glucose. On the other hand, portal and hepatic fluxes of urea nitrogen and glucose were not affected by butyrate levels in the rumen.

Effect of exogenous emulsifiers and fat sources on nutrient digestibility, serum lipids, and growth performance in weanling pigs
Article Abstract:
An experiment was conducted to study the effects of emulsifiers and fat sources on digestibility of nutrients, serum lipids and growth performance in weanling pigs. Results show that inconsistency in the results obtained from the addition of fat to diets for early-weaned pigs is due to the chosen fat source. Soybean and coconut oil were superior compared to tallow, however addition of emulsifiers increases the digestibility of tallow. Growth performance is not affected by adding fats to diet.

Impact of nutrition on pancreatic exocrine and endocrine secretion in ruminants: a review
Article Abstract:
The ruminant digestive system has a lot of unique features and yet little is understood of their adaptive response to the variety of feedstuff. An area worth exploring is the role of pancreatic enzyme and hormone secretion in dietary metabolism. Further research can lead to improvements in nutritional management and production effiency.
