NAKED OATS (Avena nuda) WITH AND WITHOUT LYSINE SUPPLEMENTATION, FOR BOARS AND BARROWS: GROWTH, CARCASS AND MEAT QUALITY, ENERGY AND NITROGEN METABOLISM

Abstract

. 1989. Naked oats (Avena nu.da) with and without lysine supplementation, for boars and barrows: growth, carcass and meat quality, energy and nitrogen metabolism. Can. J. Anim. Sci. 69 765-778. Thirty-six boars and 36 barrows were fed four diets. The control was a fortified cornsoybean meal diet. Diets 50L and l(X)L were lysine-supplemented, arld48% arfi'95%,

Effects of age/weight and castration on fatty acids composition in pork fat and the qualities of pork and pork fat in meishn x large white pigs.

“…This shows a tendency towards a rapid degree of saturation of adipose tissue with increasing age/weight, a pattern that is consistent with other reports [14, 15, 27, and 28]. As reported elsewhere the lipid from boars contained more unsaturated fatty acids than that from of castrates [6,9,29], and explains why the boar fat was softer than the castrate fat.…”

“…A reduction in the proportion of unsaturated fatty acids such as C18:2 and an increase in the proportion of saturated fatty acids such as C18:0 due to de novo synthesis of fat as the pigs become heavier [14,15,28], could be responsible for this sharp rise in fat firmness with increasing age/weight. Similarly, the higher firmness index in the castrates reflects the changes in the fatty acid profile towards increasing proportion of SFA with a corresponding decrease in the proportion of PUFA which makes the castrate fat firmer [6,9,29]. Though there was a marked decline in the nutritional index (P: S ratios) with age from 60 to 90 days and in castrates, all the values were above the minimum recommended ratio of 0.4 [1], which indicates that the meat is healthy for human consumptions with regard to its fatty composition.…”

Protein Quality of Three New Canadian-Developed Naked Oat Cultivars Using Amino Acid Compositional Data

“…One advantage of naked oats is that the groats have a higher energy and protein content than covered seeds. Naked oats have been found particularly suitable for feeding to poultry and pigs (Huían et al, 1981; Maurice et al, 1985;Cave et al, 1989;Morris and Burrows, 1986;Friend et al, 1989) and have also been successfully fed to horses and sheep (Givens and Brunnen, 1987). However, until now the most serious obstacle to establishing naked oats as a profitable agricultural crop was the absence of varieties that were truly competitive in yielding ability and other agronomic traits (Jenkins, 1968;Jenkins and Hanson, 1976; Burrows, 1986a; Schrickel et al, 1992).…”

Estimation of an acceptable β-glucan level for broiler chick diets

“…(1990 (Wood et al 199 1a, 1991b). The main differences between bran and whole-groat P-glucan, therefore are microstructural (i.e., cell-wall thickness).…”

“…inhibition de la croissance Naked oats (Avena nuda) are a valuable feed grain for laying hens (Cave et al 1989), grower-finisher broilers (Cave and Burrows 1985) and swine (Friend et al 1989). …”
