“…The lipids from the food and excreta samples were extracted using a mixture of chloroform, methanol and hydrochloric acid (60:40:1) according to the procedure of Marchello et al (1971). Chromic oxide contents of food and excreta samples were measured by atomic absorption spectrophotometry at 360 nm according to the method of Williams et al (1962) as modified by the Association of Official Analytical Chemists (1970).…”

1. Rye grain was subjected to several treatments in an attempt to alter its nutritive value for young chickens. 2. Soaking rye in water or dilute hydrochloric acid improved its nutritional quality. This was manifested by increased food intake, food utilisation, weight gain and increased apparent absorption of fat for chicks fed on a diet containing treated rye. 3. Autoclaving rye before water soaking eliminated the effect of soaking, an effect attributed to denaturation of endogenous enzymes which were responsible for the deactivation of the deleterious compound(s). 4. Autoclaving, sprouting and soaking rye in dilute sodium hydroxide decreased its nutritive value. 5. Studies with rye fractions demonstrated that the apparent absorption of fat was lower in birds fed on diets containing rye flour compared with those fed on diets containing rye bran, that greater improvement in apparent fat absorption occurred after water soaking of rye flour than similarly treating rye bran and that the effects were greater soon after initiation of the feeding of the rye diets as compared with the later part of the feeding trial.

“…Dietary lipids were extracted with an acid solvent consisting of chloroform, methanol and hydrochloric acid (60 : 40 : 1, by volume) as outlined by Marchello, Dryden and Hale (1971). Methyl esters were determined according to Sklan, Volcani and Budowski (1971).…”

Soaking of complete fattening rations high in poor roughage. 4. The effect on deposition and fatty acid composition of bovine fat

et al. 1976

The effects of diets containing variable percentages of roughage and moisture on depot fats were studied. Treatments were 25 and 45% roughage in the complete fattening diet, and 10, 50 and 75% moisture content of the diets. Depot fats collected post-slaughter from kidney, pelvic, ruminal, cod and trim fats in the carcass (mostly subcutaneous and some intermuscular) were weighed and analysed for their fatty acid composition. Increasing the quantity of roughage in the diet (from 25 to 45%) significantly decreased ruminal fat deposition. Moistening the feed significantly increased the deposition of kidney, pelvic and cod fat, and significantly reduced the deposition of fat trim in the carcass.

“…Horv'ever, the fat itself may influence feed intake. Diets containing added animal fat above about 5% of the diet decreased feed intake and rate of sain (Marchello et al 1971). The replacemerit of milo with 15% tallow has been shown to reduce feed intake and rate ofgain (Brethour et al 1958).…”

Hironaka, R. and Kozub, G. C. 1991. The influence of digestible energy concentration of the diet on feed intake and rate of gain by beef steers. Can. J. Anim. L'augmentaiion de la concentration de suif tann6 dans la ration rdduit I'ingestion quotidienne des deux ratiois, mais I'ingestion quotidienne d'6nergie digestible (DE) diminue puis augmente avec les rations de foin-concentr6. Les rations tout concentr6 n'influent pas sur la DE requise par unit6 de gain de poids' mais celle-ci augmente puis diminue avec l'accroissement de la teneur en suif tann6 des rations de foinconcentr6. La cbncentration de suif tann6 dans les rations tout concentr6 n'influe pas sur les mesures de la carcasse. L'6paisseur du gras dorsal de la carcasse diminue avec I'augmentation de Ia teneur en suiftann6 des rations de foin-concentr6. Le relbvement de la concentration de suiftann6 dans la ration augmente les teneurs en acides gras non est6rifi6s du plasma sanguin. L'h6matocrite augmente avec l'aicroissement de la teneur en suif tann6 de la ration des bouvillons nourris seulement de concentr6, mais pas de ceux nourris de foin-concentr6. La concentration de suif tann6 dans la ration n'influe pas sur la teneur en glucose sane.uin.
