The effect of dietary level of soybean oil and palm oil on apparent ileal amino acid digestibility and postprandial flow patterns of chromic oxide and amino acids in pigs

Abstract

Albin, D. M., Smiricky, M. R., Wubben, J. E. and Gabert, V. M. 2001. The effect of dietary level of soybean oil and palm oil on apparent ileal amino acid digestibility and postprandial flow patterns of chromic oxide and amino acids in pigs. Can. J. Anim. Sci. 81: 495-503. A study was conducted to evaluate the apparent ileal digestibilities of amino acids in pigs (initial weight 78 kg) fed diets supplemented with either soybean or palm oil, at either 100 or 200 g kg -1 diet. A control diet with no added fat was also evaluated. All diets contained 5 g chromic oxide kg -1 . The pigs were surgically fitted with a simple T cannula at the distal ileum, and were allowed to adapt to each experimental diet for 5 d. This was followed by 1 d of continuous collection of ileal digesta between feedings, and a second day of continuous collection separated into six 2-h postprandial time blocks to determine postprandial flow patterns of chromic oxide and amino acids. The apparent ileal leucine and arginine digestibilities were improved (P < 0.05) by 3.8 and 3.6%, respectively, with 200 g soybean oil kg -1 diet. Linear improvements (P < 0.05) were found in the apparent ileal digestibilities of serine, histidine, arginine, tyrosine, and leucine when 100 and 200 g soybean oil kg -1 diet were supplemented to the control diet, and for serine, histidine, arginine, and phenylalanine with the addition of 100 and 200 g palm oil kg -1 diet. Quadratic responses (P < 0.05) were found in the apparent ileal digestibilities of isoleucine and leucine with the addition of 100 and 200 g palm oil kg -1 diet. The postprandial flow patterns of chromic oxide and amino acids were very stable despite the different dietary treatments. Also, amino acid digestibility coefficients determined at different postprandial sampling times had low variability. In conclusion, the addition of high levels of soybean and palm oil to a semipurified swine diet increased the apparent ileal digestibilities of some amino acids. Also, the two fat sources affected some apparent ileal amino acid digestibility coefficients differently.

The Use of Crude Palm Oil in Finishing Pigs’ Diet: Effects on Growth Performance and Nutrient Digestibility

“…These two groups were different not only because of the type of oil or fat but also because of the inclusion level of diet13, which was 3%CPOmix13. The explanation could be supported by the results of Albin et al, (2001) who found that adding high levels of soybean and palm oil to a semi-purified swine diet increased the apparent ileal digestibility of some amino acids. Also, the fat sources affected some apparent ileal amino acid digestibility (Albin et al, 2001), digestible energy and ether extract digestibility (Mitchaothai et al, 2008;Yongbo et al, 2015).…”

When fat is oxidized, ADG and ADFI in nursery pigs will decrease; however, free fatty acid (FFA) concentrations of at least 53% in choice, white grease fat does not adversely affect its utilization in nursery pigs (DeRouchey et al, 2004).…”

Reduction in the protein level and addition of oil in diets for finishing pugs under different temperatures

“…This result may be related to improvement in the digestibility of crude protein, releasing more amino acids for protein deposition at the expense of fat (Albin et al, 2001). In the case of hot environment, the lower intake made possible by these conditions might have attenuated this effect.…”

Factors affecting digestibility of barley-based diets for growing pigs

“…The pigs were fed daily at 09:00 and 16:30 h (08:00 and 20:00 h for 5 days prior to and the 2 days during the ileal digesta collection periods) and given a fixed allowance for the 14-day balance period. According to the method of Albin et al (2001), a 5-day adaptation period to 12 h feeding intervals was sufficient to ensure that diurnal variations did not affect the ileal flow. Feed allowances were 1200, 1500, 1800 and 2100 g/day for the four consecutive balance periods corresponding to approximately 85% of ad libitum intake as calculated by Rao and McCracken (1991).…”
