The Effects of Nonstarch Polysaccharide Enzyme Addition and Dietary Energy Restriction on Performance and Carcass Quality of Organic Broiler Chickens

Polycystic ovary syndrome (PCOS) is one of the most common endocrine-metabolic disorders in women of reproductive age characterized by ovulatory dysfunction, hyperandrogenism and cardiometabolic risk. The overweight-obese PCOS phenotype appears to have exacerbated reproductive dysfunction and cardiometabolic risk. In overweight-obese adult women with PCOS, exercise and energy restricted diets have shown limited and inconsistent effects on both cardiometabolic indices and reproductive outcomes. We hypothesized that an early lifestyle intervention involving exercise and dietary energy restriction to prevent or reduce the propensity for adiposity would modulate reproductive indices and cardiometabolic risk in an obese PCOS-prone rodent model. Weanling obese PCOS-prone and Lean-Control JCR:LA-cp rodents were given a chow dietad libitumor an energy-restricted diet combined with or without voluntary exercise (4 h/day) for 8 weeks. Dietary energy restriction and exercise lowered total body weight gain and body fat mass by 30% compared to free-fed sedentary or exercising obese PCOS-prone animals (P<0.01). Energy restriction induced an increase in exercise intensity compared to free-feeding plus exercise conditions. Energy restriction and exercise decreased fasting plasma triglycerides and apoB48 concentrations in obese PCOS-prone animals compared to free-fed and exercise or sedentary groups. The energy restriction and exercise combination in obese PCOS-prone animals significantly increased plasma sex-hormone binding globulin, hypothalamic cocaine-and amphetamine-regulated transcript (CART) and Kisspeptin mRNA expression to levels of the Lean-Control group, and this was further associated with improvements in estrous cyclicity. The combination of exercise and dietary energy restriction when initiated in early life exerts beneficial effects on cardiometabolic and reproductive indices in an obese PCOS-prone rodent model, and this may be associated with normalization of the hypothalamic neuropeptides, Kisspeptin and CART.

Study Performance

Fattening of farm animals is a way of increasing the rate of meat deposit after maturity. Its effectiveness depends on genetic status of the animal and the diet fed to the animal. In this study, performance and carcass evaluation of balami rams finished on diets with varying energy levels were carried. Forty-eight rams of Balami breed, weighing 20.75±1.50- 22.50±1.91kg were randomly alloted to four dietary energy levels (EL): 2.20Mcal/kg (EL ), I 2.40 Mcal/kg ((EL ), 2.60 Mcal/kg ((EL ) and 2.80 Mcal/kg ((EL ) for 90 days. The feed II III IV intake and daily weight gain of the animals in each treatment were determined and the average recorded. Three Balami rams were randomly selected from each treatment and sacrificed to determine the dressing percentage (DP), carcass weight (CW), fat deposit (FD) and meat yield (MY). Data were analysed using descriptive statistics and ANOVA at á . The 0.05 FBW (kg) of Balami rams in group EL , EL , EL and EL were 41.88.6±1.97, 42.12±1.84, I II III IV 46.13±1.65 and 52.24±2.50 while the FCR of animals on treatments EL (5.3±0.28) and EL I II (5.2±0.26) were higher than EL (4.7±0.82) and EL (4.0±0.65). The DP (%) were 54.9, III IV 54.9, 55.8 and 56.1, the FD (%) were 9.00,9.59,8.92 and 11.46 and the MY (%) were 75.2, 74.7, 75.5 and 72.0 for rams on EL , EL , EL and EL The results indicate that, increasing I II III IV. levels of energy improved growth performance and carcass quality of Balami rams. Therefore, higher level of dietary energy (2.80 Mcal/kgDM and 14% CP) could be suggested for optimizing growth performance and meat quality of Balami ram under fattening condition.

Main Effects

Recently ,there is an incrase interest in fattening camals in Iran .This trial aimed to define the influence of dietary energy and protein levels on performance and carcass quality of camels in khorasan province.For 80 days, nine diets with three metaboliseble energy 10.9, 8.8 or 7.6 MJ /kg DM and three crude protein levels 140, 120, or 100 g/kg DM were offerd ad lib to thirty six camels (mean initial weight 183 kg ± 7.7) , where each treatment were randomly allocated to four animals, that were housed individually. Food intakes were recorded daily. Throughout the trial , all animals were weighed at fortnightly intervals. At the end of the project ,two animals from each treatment were slaughtered and carcass quality were determined. Data were analysed as a 3x3 factorial Anova, with energy and protein were the main effects.
