Comparison Of Carcass Characteristics, Meat Quality, And Fatty Acid Composition In Slowand Fast-Growing Broilers At Different Slaughter Weights, Büşra Yaranoğlu, Hi̇lal Çapar Akyüz, Esi̇n Ebru Onbaşilar
Turkish Journal of Veterinary & Animal Sciences
This study aimed to compare the slaughter, meat quality characteristics, and fatty acid composition of fast-growing (FAG) and slow-growing (SWG) broilers at different slaughter weights. In the experiments, a total of 90 carcasses were used: 45 SWG (Hubbard-Isa Red JA) and 45 FAG broilers (Ross 308) with 15 carcasses from each slaughter weight group (1500 ± 50 g, 2000 ± 50 g, 2500 ± 50 g). Hot carcass yield and cold carcass yield detected in the FAG broilers were higher than in SGW broilers (p < 0.001). As the weight of slaughter increased, hot carcass and cold carcass yield increased (p < 0.001). The breast percentage was significantly lower in the SWG broilers compared to the FAG broilers (p < 0.001). In contrast, thigh, wing, and abdominal fat percentages were higher in the SWG broilers (p < 0.001). The breast percentage increased as the slaughter weight increased (p < 0.001). SWG broilers had significantly lower pH, except for the pH 24 of the thigh meat (p < 0.01). The L*, a*, and b* values of the SWG broilers were lower than the FAG broilers (p < 0.01). In terms of a* values determined initially and at the 24th h in the breast and thigh meat, the 1500 g slaughter weight group had by far the highest value (p < 0.01). SWG broilers had significantly lower values in terms of cooking loss, water-holding capacity, and drip loss (p < 0.001). C18:2ω6 was detected at higher amounts in the FAG broilers (p < 0.05). The FAG broilers had higher PUFA, desired fatty acids, PUFA/SFA, and thrombogenic index values (p < 0.05). The results show that FAG broilers can meet the strong worldwide demand for meat quantity and quality. Slaughter weight changes only affected the quantity of the meat.

Turkish Journal of Veterinary & Animal Sciences
This study was conducted to investigate the effects of diet and exogenous enzymes on growth responses and micronutrient digestibility of broilers. Day-old broilers (n = 256) were distributed into a 2 x 2 factorial design and were fed on two basal diets: soybean (T1) or canola (T2) meals as such, or supplemented with enzymes up to 21 days. Feed intake (FI) and live weight (LW) to 21 days on the T2 diet was higher (P < 0.001) than that on T1. Feed conversion ratio (FCR) was better (P < 0.01) on T1 than on T2 at 21 days. Enzymes generally improved (P < 0.001) FI, FCR, and LW. The digestibility of histidine was higher (P < 0.05) on T2, but lysine digestibility was higher (P < 0.01) on T1 at 21 days. Histidine, threonine, lysine, valine, isoleucine, and phenylalanine digestibility was improved (P < 0.05) in the supplemented diets. Mineral digestibility was unaffected (P > 0.05) by diet, but enzymes increased (P < 0.05) digestibility of P, K, Mn, and Cu at 21 days. The digestibility of Cu, Zn, and Mg was higher (P < 0.05) on T2, whereas Ca digestibility was greater (P < 0.05) on the T1 diet. Broilers' growth responded positively to enzyme diets, probably due to improvement in nutrient digestibility.

The effects of in ovo administration of β-hydroxy-β-methylbutyrate (HMB) on broiler performance, intestinal health, and immunity were investigated. At day 18 of incubation, fertile eggs were divided into negative (no injection) and positive (physiologic serum injection) controls and three HMB treatment groups. HMB solution was injected at 0.1% (Group 1), 0.2% (Group 2), and 0.3% (Group 3) concentrations. There were no significant differences between the groups for live weight gain, feed conversion rate, and hot carcass, breast meat, liver, and heart weight. However, the gizzard weight in Group 1 was significantly higher than those in the other groups (P < 0.05). Although the intestinal villi lengths in the treatment Groups 1 and 3 on day 20 were greater than those in the control groups (P < 0.01), at the end of the experiment there were no significant differences among the groups. For antibody levels, the differences between groups on days 4 and 42 were highly significant (P < 0.01), and the antibody levels in Group 2 were higher than those in the other groups. Separately, growth performance and antibody levels were positively correlated with the length of villi in Group 2 (HMB 0.2%).

Turkish Journal of Veterinary & Animal Sciences
To clarify the effect of acetic acid on the electrocardiographic parameters of pulmonary hypertensive broilers, chicks were reared at high altitude and treated with acetic acid (0.4 and 0.9 g/L) for 45 days. The right ventricle-to-total ventricle ratio was noted as an index of pulmonary hypertension that was significantly (P < 0.05) decreased in the treated groups. S amplitudes were significantly decreased only at 36 days (leads II and III) and 45 days (lead aVF) in many treated groups. There were significant (P < 0.05) reductions of T amplitudes at 28 days (leads aVR and aVL) and 36 days (lead aVL), and significant elevations of QRS (leads II, III, and aVF) and QT intervals (leads II, aVR, aVL, and aVF) at different ages of many treated groups. R amplitudes were significant (P < 0.05) at 28 days (leads aVL and aVF, at both doses of acetic acid), 36 days (leads aVR and aVL, at 0.4 g/L of acetic acid), and 45 days (lead aVR, at both doses of acetic acid). The RR interval also significantly increased at 28 days (leads aVR and aVL) and 45 days (lead aVL). It was concluded that acetic acid modulates induction of ventricular hypertrophy, dilation, and arrhythmia. These effects are detectable in many electrocardiographic parameters.

This study aimed to determine the optimum time of pre-slaughter feed withdrawal for broiler chickens to maintain profitable and hygienic meat production and to determine its effect on the meat yield, microbiological structure of gut content and microbiological quality of the carcass. A total of 100 birds were allocated to 4 identical 2 m^2 pens in a commercial broiler house, each pen housing 25 birds. The feed withdrawal durations were 18 h (group 1), 12 h (group 2), 6 h (group 3) and 0 h (group 4). The percentage live weight loss increased as the feed withdrawal period increased (P < 0.05). The meat yield in group 4 was lower than that in the other groups (P < 0.05). Full gizzard weight in group 1 was lower than that in groups 3 and 4, and group 2 parameters were lower than group 4 parameters (P < 0.05). Salmonella positive carcasses numbered 1 in group 1, 1 in group 2, 0 in group 3 and 2 in group 4. The only significant difference found among the groups was for coliform bacteria. The coliform count in group 1 (7.54 ± 0.100) was significantly different from that in group 2 (7.00 ± 0.159) and group 3 (7.08 ± 0.169) (P < 0.05).

This study was conducted to evaluate the effects of copper as tribasic copper chloride on serum biochemical values and growth performance of broilers intoxicated with aflatoxins. Aflatoxins significantly decreased the level of albumin (P < 0.001), total protein (P < 0.001) and total cholesterol (P < 0.01), and increased the activities of alanine amino transferase, L-lactic dehydrogenase and alkaline phosphatase (P £ 0.001) in serum. These AF-induced changes were significantly improved by adding tribasic copper chloride to the diet. The decrease in serum copper concentration induced by aflatoxin was reversed by tribasic copper chloride. Serum zinc concentrations were not affected in tribasic copper chloride and tribasic copper chloride plus aflatoxin groups. Serum iron levels decreased in all the treatment groups significantly (P < 0.05). Aflatoxins caused significant decrease in the body weight gain and significant increase in the feed conversion ratio. Adverse effects of aflatoxins on feed conversion ratio were reversed by tribasic copper chloride supplementation to the diet. It is suggested that tribasic copper chloride might be used for reducing the adverse effects of aflatoxins in broiler production.

Weighing data from 389 broiler carcasses and parts formed the research material. The carcasses were divided into 6 different groups according to their weight. Cutting up shrinkage and percentage rates of the parts in the total weight were determined. Gross and net changes in enterprise income were determined according to the summer and winter prices of the whole body and parts. It was determined that cutting up caused a 4.03% net increase in enterprise income at summer prices and a 0.91% net increase at winter prices. It was also determined that cutting up carcasses smaller than 1400 g and greater …

The influence of 2 enzyme supplements for diets based on wheat with high or low viscosity on performance and some intestinal parameters of male broiler chickens were investigated. The experiment was of 2 x 3 factorial design, with 2 types of wheat (high or low viscosity) and 3 enzyme treatments (none, Avizyme 1300-xylanase or Avizyme 1500-amylase). Ileal digesta viscosity was significantly (P < 0.029) higher in birds fed with high viscous wheat than with low viscous wheat. Ileal digesta viscosity (P < 0.001) and dry matter content (P < 0.002) were significantly reduced by both enzyme preparations. Body weight gain, feed intake, dry matter intake, feed conversion ratio, DM retention and wet or dry excreta output were not significantly (P > 0.05) affected by all treatments. There were no significant interactions (P > 0.05) between the effects of wheat type and enzyme supplementation. In conclusion, the supplementation of high or low viscous wheat-based diets with the enzyme preparations of amylase …

This trial examined 1350 sex-separated broilers at 24 days of age. Chicks were fed standard broiler starter diet for the first 21 days. Isocaloric grower diets (16.84%, 18.00% and 19.46% crude protein, respectively) were offered to broilers housed in sex-separated and mixed-sex pens from days 24 to 45 of the experimental period. While the body weights of sex-separated and mixed-sex broilers were similar, diet protein level and sex had a significant effect on the body weight of broilers during the experimental period (P < 0.01). Male broilers consumed more feed and had better feed conversion than females (P < 0.01). However, separate sex rearing had no significant effect on feed consumption or feed conversion rate (P > 0.05). As diet protein level decreased feed consumption increased numerically and feed conversion was negatively affected (P …
