“…It is possible that the added dietary fat affected digestibility of some amino acids by altering gastrointestinal structural and functional measurements. Li et al (1990) reported that intestinal villi were longer and rounder in weanling pigs fed a 50:50 combination of soybean oil:coconut oil versus the two fat sources individually. Also, Lindley et al (1995) found that improvements in absorptive function measured in vitro were induced in rats by feeding polyunsaturated fatty acids.…”

“…Jørgensen et al (1985) reported an increase of 1-2% in the ileal digestibility of CP, lysine and methionine, but not cystine and threonine, in growing pigs fed a diet containing 150 g fat kg -1 diet versus 30 g fat kg -1 diet. Li et al (1990) reported that CP digestibility was not affected by the addition of soybean oil, coconut oil, or a 50:50 combination to diets for weanling pigs. Imbeah and Sauer (1991) and Li and Sauer (1994) both noted improvements (up to 4.9%) in the ileal digestibility of some amino acids when canola oil was added to diets for growing and weanling pigs, respectively.…”

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 effect of fat type on the digestive utilisation of diets has been widely studied in swine and chickens (Li et al, 1990;Preston et al, 2001) but there is less information in rabbit. Almost all authors fi nd that dietary digestibility increases when fat is included in the diet (Xiccato, 1998;Bhatt and Swain, 2003;Cesari et al, 2009) and that a greater degree of non saturation of fatty acids (FA) in fat enhances the apparent digestibility of this fraction (Maertens et al, 1986;Santomá et al, 1987).…”

ABSTRACT:The effects of the dietary inclusion of fats with different origin (lard or vegetal oil), fatty acid profi le (linseed or sunfl ower), oxidation level (fresh, peroxidised: 11 d at 55ºC or oxidised: 31 h at 140ºC) and vitamin E supplementation (0 or 100 ppm) on the rabbit diet apparent digestibility were studied. Digestibility coeffi cients of dry matter, organic matter, crude protein, ether extract and gross energy were determined in eight diets using 58 rabbits aged 49 d. Contrast analysis between groups of diets showed that lard, characterised by a greater saturated fatty acid content, compared with vegetal oils, rich in unsaturated fatty acid, reduced the apparent digestibility of ether extract (62.3 vs. 68.4%; P=0.0329). However, there were no signifi cant differences in the nutrient digestibility when linseed or sunfl ower oils (rich in ω-3 or in ω-6 polyunsaturated fatty acids, respectively) were compared. The oxidation degree of the sunfl ower oil and the supplementation with 100 ppm of vitamin E to the diets did not modify the apparent digestibility values of any dietary fraction.

RESUMO -Visando avaliar o efeito de duas fontes lipídicas (óleo de soja e gordura de coco) e de quatro níveis de energia digestível (3350, 3450, 3550 e 3650 kcal/kg de ração) sobre o desempenho de suínos machos inteiros, dos 60 aos 100 kg, foram utilizados oitenta animais, distribuídos num arranjo fatorial 2 x 4 (fontes x níveis de energia), em delineamento de blocos ao acaso, com cinco repetições de dois animais por baia. As rações experimentais, formuladas à base de milho, farelo de soja e suplemento mineral-vitamínico; foram fornecidas à vontade até o fim do período experimental, quando os animais atingiram o peso médio de 100,40 ± 5,67 kg. Não houve efeito do nível de energia digestível (ED) sobre o consumo de ração diário e ganho de peso diário; no entanto, estes parâmetros foram influenciados pela fonte de energia, sendo os melhores resultados obtidos com a utilização da gordura de coco. A conversão alimentar foi influenciada de forma quadrática pelos níveis de ED, quando se utilizou a gordura de coco. Não se observou efeito do óleo de soja sobre a conversão alimentar. A eficiência de utilização da energia para ganho melhorou de forma quadrática, com a utilização da gordura de coco e piorou linearmente com o uso do óleo de soja nas rações. O consumo de energia digestível não foi influenciado pela variação dos níveis de ED e o consumo de lisina diário também não foi influenciado pelos níveis de ED, embora tenha sido maior quando a gordura de coco foi utilizada como fonte lipídica. Rações contendo gordura de coco como fonte lipídica proporcionaram melhor resultado de ganho de peso. A melhor resposta de conversão alimentar dos animais que receberam as rações contendo gordura de coco foi estimada no nível de 3583 kcal.Palavras-chave: gordura de coco, nutrição, óleo de soja, suínos em terminação Lipidic Sources and Digestible Energy Levels in Rations for 60 to 100 kg BoarsABSTRACT -To evaluate the effects from two lipid sources (soybean oil and coconut oil) and of four energy levels (3350, 3450, 3550 and 3650 kcal/kg ration) on performance from 60 to 100 kg boars, eighty animals were used. The experimental design of randomized blocks with a factorial arrangement of 2 x 4 (sources x energy levels), with five replications of two animals per box, was used. Experimental diets formulated on the basis of maize, soybean meal and vitaminic and mineral supplement were feed ad libitum until the end of the experimental period when animals reached 100.40 ± 5.67 kg average weight . There was no effect of the digestible energy (DE) level on the daily feed intake neither on the daily weight gain; however, these parameters were influenced by the energy source and the best results obtained with the use of the coconut oil. The feed:gain ratio was influenced in a quadratic way by the DE levels, when using the coconut oil. No effects of the soybean oil were observed on feed:gain ratio. The efficiency of the energy use for weight gain was improved in a quadratic way when using the coconut oil and linearly worsened when using the so...
