“…Crude protein digestibility varied from 18.2 to 81.3% in lambs and from 75.9 to 78.4% in kids. Lipid digestibility was approximately 9O% for both species and all treatments; these results are slightly higher than those reported by Faichney et al (1973) rt93 in lambs but similar to those found by Delort-Laval and Gueneau (1971) …”

“…Polyunsaturated fatty acid levels in tissues of cattle and sheep were significantly elevated by feeding formaldehyde-treated lipid [29][30][31]. Approximately 18-25% of the linoleic acid consumed in formaldehyde-treated lipid was stored in body tissues of cattle [32], while 50-60% storage was reported for sheep [31,33].…”

The increased need for intestinal absorption of unsaturated fatty acids in cattle is driven mainly by nutritional guidelines that promote reduced intake of saturated fatty acids by humans, and by reports of enhanced animal performance (such as reproductive performance) when additional essential fatty acids are supplied. A duodenal flow dataset was compiled from 25 published studies that provided up to 93 observations on fatty acid intakes and ruminal outflows across a multitude of unprotected and protected fat sources. Control diets with no added fat and diets containing unprotected fat sources had similar and predictable ruminal losses of unsaturated fatty acids (86% for linolenic and oleic acids, and 82% for linoleic acids). Rumen protection technologies that have emerged over the years involve either encapsulation of unsaturated fatty acids inside a microbial-resistant shell (such as formaldehyde-treated or lipid encapsulated), or alteration of fatty acid structure (such as calcium salts or fatty amides) to resist action of microbial enzymes. Calcium salts of fatty acids, because they are available commercially, comprised the majority of observations in the duodenal flow dataset. Meta-analysis of the duodenal dataset that included random study effects revealed only a few instances where protected fat sources gave ruminal losses of polyunsaturated fatty acids that were appreciably lower than what was seen for unprotected fats. Future challenges include enhancing protection characteristics of existing rumen-protected fat sources, and development and commercialization of novel protection strategies.

“…The supposed relationship between dietary saturated fats and cardiovascular degeneration in man has stimulated an interest in the possibility of increasing the levels of polyunsaturated fatty acids, in particular linoleic acid, in ruminant meat and milk (1)(2)(3)(4)(5). Little is known, however, about the effects of such increased levels of linoleic acid upon the metabolism of ruminant tissues.…”

Effect of dietary safflower oil upon lipogenesis in neonatal lamb

The effect of dietary safflower oil upon lipogenesis has been investigated in neonatal lambs. Preliminary experiments with lambs suckled by their mothers showed that there was a 10-fold increase in the rate of incorporation of [14-C] from acetate into fatty acids in adipose tissue slices during the first 10 days post partum. Barely detectable rates of [14-C] acetate incorporation into fatty acids were found in liver slices from lambs during the same period. In lambs given cows' milk from birth untill 11 days of age, there was also a 10-fold increase in the rate of lipogenesis in adipose tissue slices. Supplementing the diet of cows' milk with safflower oil (5 ml/lamb/day) resulted in significantly lower rates of lipogenesis in adipose tissue slices from 11 day old lambs. Administration of safflower oil had no effect upon the concentration of unesterified fatty acids, including linoleic acid, in the lamb adipose tissue slices. The data show that lipogenesis in ovine adipose tissue, like that in rodent liver and adipose tissue, is sensitive to dietary polyunsaturated fatty acids, and that, for the neonatal lamb, the effect of polyunsaturated fatty acids upon lipogenesis is not dependent upon an increase in the tissue concentration of polyunsaturated fatty acids.
