“…The abdominal fat yield of male and female broilers was 1.49% and 1.86%, respectively (Table 1), and were significantly different, demonstrating that females deposit more abdominal fat than males, as previously observed by Kubena et al (1974), who obtained values of 1.50% for males and 2.67% for females. SouzaSmith & Siewerdt (2005) reported that fat deposits are proportionately larger in females than in males, mainly because females present larger adipocytes, as also mentioned by the Cobb-Vantress manual (2001), Chiu (2001), Rostagno (2005), Pereda (2005), Olivo & Olivo (2006), Centenaro et al (2008), and Murakami et al (2010).…”

ABSTRACTwere obtained for males and females, respectively. Female abdominal fat contained higher proportion of oleic acid (53.87%) followed by palmitic acid (30.07%), whereas 34.69% palmitic acid, 31.92% oleic acid, and 25.30% linoleic acid were determined in males. The proportions of the evaluated fatty acids were significantly different (p>0.05) between males and females, except for palmitic acid. The DSC analysis showed no significant difference (p>0.05) between sexes for melting and crystallization points. It was concluded that sex influences abdominal chicken fat yield, chemical composition, color, and DSC parameters.

Nine starting and rearing diets (three energy levels each with three fat levels) were fed to commercial White Leghorn chicks from hatch to 20 weeks of age. As noted in the earlier papers of this series, pullets fed the high energy rearing diets showed significant (P = 0.05) reductions in feed intake, however, average daily caloric intake was greater (P = 0.05) for pullets consuming the low energy rearing diets. Fat content of the diet had not influence on either daily feed (g.) or caloric (kcal.) intake. Energy content of the diets failed (P = 0.05) to affect parameters related to body growth and development, hepatic citrate-cleavage and "malic" enzyme activity and liver or body composition. Fat content of the diet depressed hepatic enzyme activity while no effect was noted on body weight, liver weight or body composition. The onset of sexual maturity altered lipid metabolism in the developing pullets. Significant (P = 0.05) energy level by fat level interactions were noted in only two of the 20 parameters studied in this experiment. In vitro assay of hepatic citrate-cleavage and "malic" enzyme activity proved to be of little value in predicting hepatic lipogenic activity and subsequent effects on liver and total body composition.

“…Promotion of body fat deposition was observed in chicks and broilers under a high ambient temperature (Kubena et al, 1972(Kubena et al, , 1974. According to Christon (1988) and Katsumata et al (1996), backfat depth and the total amount of fat stored in the pig's body were greater in pigs kept at high ambient temperatures than in pigs kept at low ambient, or thermoneutral, temperatures.…”
