“…High energy consumption was also shown to increase the relative weights of abdominal fat (Deaton and Lott, 1985; Jones and Wiseman, 1985). A previous study demonstrated that a high energy diet increased the relative weights of abdominal fat compared to a low energy diet (Deaton et al, 1983), which is in agreement with the results of the present study.…”

This experiment was conducted with male chicks to investigate the influence of hormones and nutrients on the development of fatty liver syndrome (FLS) as well as the effects of dietary lipotropic factors on hepatic fat accumulation and lipogenic enzyme gene expression. A total of two-hundred sixteen 4-wk-old Hy-Line male chicks were divided into six groups and fed an experimental diet (T1, low-energy diet with low levels of lipotropic factors; T2, high-energy diet with low levels of lipotropic factors; T3 and T5, low-energy diet with high levels of lipotropic factors; T4 and T6, high-energy diet with high levels of lipotropic factors) for six weeks. The chicks in T5 and T6 groups were treated with intramuscular injections of estradiol benzoate for three days prior to biopsy and clinical analysis of FLS. Chicks treated with estrogen had significantly greater liver weights than untreated chicks. The abdominal fat contents were increased in chicks consuming high-energy diets as compared to those consuming low-energy diets. Treatment with estrogen significantly increased the concentrations of serum cholesterol, triacylglycerol and phospholipid (p<0.05). The hepatic triacylglycerol levels were tenfold higher in the estrogen treated chicks than in the untreated chicks. There were no significant differences in malondialdehyde levels between the treatment groups. Estrogen treatment dramatically increased the levels of fatty acid synthetase, acetyl-CoA carboxylase and ApoB mRNA. The results indicated that treatment with exogenous estrogen in growing male chicks induced hepatic fat accumulation, which might be partially due to increased lipogenic enzyme gene expression.

“…These differences could be related to differences in propensity to fatten. In the present study female birds consistently had a much higher percentage of carcass fat and non-carcass fat than did males DEATON et al (1983) found that within each dietary energy level, the abdominal fat in females was higher percentage of live body weight than in males. Also, BECKER et al (1981b) reported that compared with females, males had lower percentage of carcass fat (12 vs. 13.7%).…”

Abstract. The effects of breed (Hubbard and Anak), sex and diet (two levels of protein (high or low) with two levels of crude fiber (low or high) at each level of protein) on fat yields and partitioning among the depots were studied. No significant differences were found between breeds in fat yields and in fat partitioning among the major fat depots. Expressed as a percentage of live body weight, females had a greater percentage of non-carcass fat, carcass fat and total body fat than males. Females tended to partition more of their fat to non-carcass fat, whereas males tended to partition more of their fat to carcass fat. The effects of diet were consistent over the breeds and for all fatness traits. Non-carcass fat, carcass fat and total body fat yields were greatly depressed and favorable fat partition between depots was achieved through feeding birds high protein- high fiber diets. These birds tended to partition more of their fat to carcass fat depots (more valuables) and less to non-carcass fat depots. Breed x sex, breed x diet and sex x diet interactions did not significantly influence most of fatness traits indicating that the factors under consideration act independently of each other. Significant sex x diet interactions was found for carcass fat and total body fat relative to live body weight: the sexual dimorphism in low protein diet is more pronounced than in high protein diets. The differences between sexes in their response to diet for these traits might have important implications.

“…Much research demonstrated that high level of dietary energy resulted in higher body weight gain (Pesti & Smith, 1984;Leeson et al, 1996a;Leterrier et al, 1998), and lower FCR (Deaton et al, 1983). In contrast, a dilution of dietary energy and protein increased feed intake (Leeson et al, 1996b), and that was possibly because the broiler is able to control the feed intake based on the energy level in the diet (Leeson et al, 1996b).…”

Changes of haematic parameters, redox status and mitochondrial complex activity in the heart and liver of broilers fed with different density diets under low ambient temperature

This experiment was conducted to investigate the influence of dietary nutrient density on haematic parameters, oxidative status and mitochondrial complex activity in the heart and liver of broilers under low ambient temperature. Eight-day-old male ROSS-308 chickens were randomly divided into two treatments fed with normal (control) and high metabolizable energy (ME) and crude protein density (H) diets. A high nutrient density diet increased body weight gain and reduced the feed conversation ratio during the first 3 weeks. Increased ascites-related mortality (weeks 4 to 6), right ventricle/total ventricle (week 6), blood haemoglobin (weeks 2 and 4) and mean corpuscular haemoglobin (week 2) were observed in treatment H. Levels of malonaldehyde and protein carbonylation were increased at week 4, and activities of glutathione peroxidase at week 4 and CuZn superoxide dismutase and catalase at week 6 were decreased in the heart; only malonaldehyde (week 6) was increased in the liver in treatment H. Relative mRNA expression of hypoxia inducible factor-1 (heart) was increased and heme oxygenase-1 (heart and liver) was decreased at week 4 in broilers fed with high ME and protein diet. Activities of mitochondrial complex III and IV (week 6) in the heart, and complex I (week 6) and complex III and IV (week 4) in the liver were decreased in treatment H. In conclusion, high levels of dietary ME and protein resulted in oxidative stress and high incidence of ascites in broilers under low ambient temperature. Heart dysfunction was primarily attributed to ascites development, in which oxidative injury and inhibition of mitochondrial complex activity were involved.
