Growth Performance, Plasma Fatty Acids, Villous Height and Crypt Depth of Preweaning Piglets Fed with Medium Chain Triacylglycerol

Abstract

A study was conducted to investigate the effects of feeding medium chain triacylglycerol (MCT) on growth performance, plasma fatty acids, villus height and crypt depth in preweaning piglets. A total of 150 new born piglets were randomly assigned into one of three treatments: i) Control (no MCT); ii) MCT with milk (MCT+milk); iii) MCT without milk (MCT+fasting). Body weight, plasma fatty acid profiles, villus height and crypt depth were measured. Final BW for the Control and MCT+fasting was lower (p<0.05) than MCT+milk. The piglets fed with MCT regardless of milk provision or fasting had greater medium chain fatty acids (MCFA) than the Control. In contrast, the Control had greater long chain fatty acid (LCFA) and unsaturated fatty acid (USFA) than the MCT piglets. The piglets fed with MCT regardless of milk provision or fasting had higher villus height for the duodenum and jejunum after 6 h of feeding. Similar observations were found in piglets fed with MCT after 6 and 8 days of treatment. This study showed that feeding MCT to the piglets before weaning improved growth performance, with a greater concentration of MCT in blood plasma as energy source and a greater height of villus in duodenum, jejunum and ileum.

Effects of dietary supplementation of red pepper (Schinus terebinthifoliusRaddi) essential oil on performance, small intestinal morphology and microbial counts of weanling pigs

“…Therefore, both additives (RPEO and chlorohydroxyquinoline) improved villi health, compensating for the lowered VD, providing similar growth performance to the negative control. Previous studies have shown that higher VD does not always result in higher nutrient absorption rates, once enterocyte maturity also plays a key role in the absorption rate.…”

Effects of dietary oil sources, calcium and phosphorus levels on growth performance, carcass characteristics and bone quality of broiler chickens

“…In addition, oil improves the absorption of oilsoluble vitamins, increases the palatability of rations, reduces pulverulence, increases the efficiency of the consumed energy (Baiao & Lara 2005;Chwen et al 2013) and also reduces the rate of passage of digesta in the gastrointestinal tract, which gives room for adequate and efficient absorption of the nutrients present in such diet (Baiao & Lara 2005). Furthermore, the fatty acid profile of muscle tissue reflects the dietary fatty acid profile (Abdulla et al 2015).…”

Effects of dietary oil sources and calcium : phosphorus levels on growth performance, gut morphology and apparent digestibility of broiler chickens

“…Hence fat is widely used in broiler diets to meet the energy requirements of fast growing modern strains (Baião & Lara, 2005). In addition, dietary fats enhance the absorption and utilization of fat-soluble vitamins, increase the palatability of rations, reduce pulverulence, improve the efficiency of the energy consumed (Baião & Lara, 2005;Zulkifli et al, 2007;Chwen et al, 2013) and reduce the rate of passage of digesta in the gastrointestinal tract, which gives room for adequate and efficient absorption of the nutrients present in such diets (Baião & Lara, 2005). Moreover, the fatty acid profile of muscle tissue reflected the dietary fatty acid profile (Maroufyan et al, 2013;Abdulla et al, 2015).…”
