  • A feeding trial was conducted to investigate the effects of the addition of corn distiller's dried grains with solubles (DDGS) to broiler diets on growth performance and meat characteristics. A total of 3,200 d-old, unsexed Cobb-500 broiler chicks were randomly allotted to 16 pens (replicates), with 200 chicks per pen. There were four diet treatments (0, 5, 10, and 15% DDGS), and four replicates per treatment. From 8 to 21 d of age, the birds were fed broiler starter diets containing similar energy (TMEn 3,100 kcal/kg) and protein (21.6%) contents. From 22 to 35 d of age, they were fed grower diets containing similar nutrients (3,150 kcal/kg, 19.5% crude protein). No significant difference was found in growth performances among the four treatments. As the DDGS level increased, the concentration of unsaturated fatty acids in meat increased (p<0.05). The color scores of breast and thigh muscles were not significantly influenced by DDGS, however, the yellowness of shank increased significantly by the addition of DDGS. The hardness of breast and thigh meats was not affected by the addition of DDGS. It was shown that the use of DDGS in broiler diets up to 15% could decrease the feed cost by replacing part of corn and soybean meal, without any negative effect on growth performance and meat qualities.

  • This experiment was conducted to investigate the effects of Bamboo Vinegar Liquid(BVL) on performance and meat quality of broiler ducks for 5 weeks. One hundred broiler ducks were divided into 4 groups with S replicates per treatment. Dietary levels of food waste 0%, 1%, 2% and 4% were included in experimental diets. The growth performance and carcass weight of broiler duck fed BVL supplement diets were not significantly different(P>0.05) from the control birds. The lipid content was decreased(P<0.n) by addition of BVL 2% and 4%, whereas the protein was increased(P<0.05). The cholesterol content and TBA in breast meat were significantly(P<0.05) decreased by addition of BVL. palmitic acid of fatty acid composition were decreased by addition BVL 2% and 4% whereas linoleic acid was increased by addition of BVI. 2% and 4%. The odor, appearance and taste of sensory evaluation were improved by addition BVL 1% and 2%. The results of this study indicate that dietary supplemental BVL 1% and 2% may improve the meat quality of broiler ducks.

  • Effect of garlic on cholesterol and selenium (Se) levels, and fatty acid composition in the broiler chicks (Indian River) fed diet containing 0, 2, 4, 6, and 10% lyophilized garlic powder (GA) for 6 weeks were determined. Supplementation of garlic powder significantly decreased cholesterol level in broiler compared to the control (p<0.05). Se levels were not significantly different (p>0.05) among treatment groups. Percentages of $C_{16:0}$ and $C_{18:1}$ were gradually decreased ($C_{16:0}$;20.62% of total fatty acid in the control to 17.71 % in 10% GA; $C_{18:1}$;34.08% in the control to 30.71 % in 10% GA), while that of $C_{18:2}$ was increased from 28.69% in the control to 35.89% of 10% GA diet (p<0.0l). These results demonstrate some active components of garlic reduce cholesterol level and affect fatty acid metabolism.

  • This study was conducted to determine the effects of dietary supplementation with CLA (0, 0.5, 1.0, 1.5, and 2.0%) on the proximate composition, sensory evaluation, pH, TBARS, cooking loss, WHC, shear force and objective color of chicken meat. Two hundred broiler chickens (Arbor Acre Broiler, male) were randomly assigned to five groups, fed for five weeks, and slaughtered. The proximate composition and crude protein of thigh muscle from the 1.5% and 2.0% CLA groups were significantly higher than the other groups (p<0.05), however there was no difference in moisture, crude fat, and crude ash. Based on sensory evaluation, tenderness, juiciness, and flavor were not significantly different among the treatment groups. The pH of thigh muscle from the CLA treated groups was higher than the control, and significantly increased with the increasing levels of CLA in the broiler diets (p<0.05). TBARS values were significantly lower in the CLA treated groups, and decreased with increasing CLA levels in the diet (p<0.05). Therefore, CLA may improve the shelf life of chicken meat. WHC, shear force, and meat color did not show any significant variation in this study. In conclusion, the accumulation of CLA and the production of fresh chicken meat without changes in meat quality can be achieved through supplementation with 2% CLA. Accumulation of CLA in chicken meat significantly increased with increasing CLA levels in the diet.

  • The current study was conducted to evaluate the effect of music enrichment on the live body weight of chickens and meat quality grade of the carcasses. Fourteen flocks at four broiler farms with identical windowless houses were provided with identical starter and finisher diets. These were either exposed to classical music or not exposed to any music from the starter to slaughter age. At 30 days posthatch, the chickens were transported from farms to a slaughterhouse. Two hundred carcasses from each flock were randomly selected for measurement of the carcass traits by the licensed meat inspectors at the slaughterhouse. The live body weights at the slaughter age were not significantly different between the two treatments. In addition, music enrichment did not affect meat freshness (i.e., torrymeter values) nor did it affect other carcass trait variables including percentage of bruises, flesh blemishes, abnormalities, and quality A grade. In conclusion, music enrichment did not affect the body weight or carcass quality of broiler chickens.

  • The objective of this study was to examine the effects of high and low chilling temperature on the water-holding capacity (WHC) and tenderness of hot-boned breast meat of broiler chickens. Breast meat was obtained from 32 broiler chickens within 15 min post-mortem (PM), and then divided into two groups. One group was chilled at $-1^{\circ}C$ and the other group was stored at $30^{\circ}C$ for 3 hr, and then all the samples were chilled at $2^{\circ}C$ until 24 hr PM. During the storage, their physicochemical characteristics were tested at 15 min, 3 hr and 24 hr PM. These included pH, R-values, cooking losses, sarcomere length, MFI, and shear force of the breast meat, none of which was different (p>0.05) between the two temperature treatments at $-1^{\circ}C$ and $30^{\circ}C$. However, sarcomere length was shortened more at $-1^{\circ}C$ than at $30^{\circ}C$, MFI was larger at $30^{\circ}C$ than at $-1^{\circ}C$, drip loss was greater at $30^{\circ}C$ than at $-1^{\circ}C$, and WHC was lower at $30^{\circ}C$ than at $-1^{\circ}C$(p<0.05). In brief, in terms of yield and tenderness, broiler breast meat stored at $-1^{\circ}C$ was superior to that stored at $30^{\circ}C$.

  • The objective of this experiment was to assess the use of different vitamin D metabolites in the feed of broiler chickens and the effects of the metabolites on performance, bone parameters and meat quality. A total of 952 one-day-old male broiler chicks were distributed in a completely randomised design, with four treatments, seven replicates and 34 birds per experimental unit. The treatments consisted of four different sources of vitamin D included in the diet, $D_3$, $25(OH)D_3$, $1,25(OH)_2D_3$, and $1{\alpha}(OH)D_3$, providing 2000 and 1600 IU of vitamin D in the starter (1 to 21 d) and growth phases (22 to 42 d), respectively. Mean weight, feed:gain and weight gain throughout the rearing period were less in animals fed $1{\alpha}(OH)D_3$ when compared with the other treatments (p<0.05). No significant differences were noted among the treatments (p>0.05) for various bone parameters. Meat colour differed among the treatments (p>0.05). All of the metabolites used in the diets, with the exception of $1{\alpha}(OH)D_3$, can be used for broiler chickens without problems for performance and bone quality, however, some aspects of meat quality were affected.

  • An experiment was conducted to investigate whether Saccharomyces cerevisiae(S. cerevisiae) could improve the growth performance and meat quality of broiler chicks. Day old 160 male broiler chicks were fed one of the two experimental diets without (0.0 %) or with S. cerevisiae (3.0 %) for five wks. Each treatment consisted of eight cages with 10 chicks per cage. Feed and water were provided ad libitum. Although not significant, BW gains of S. cerevisiae fed chicks tended to increase during 4∼5 wk of age. The addition of S. cerevisiae into the control diet significantly lowered the shear force in raw drumstick meat (P<0.05). After 10 d of incubation, significantly lower levels of oxidation products were found (P<0.05) in drumstick meats and skin samples from broiler chicks fed diets enriched with S. cerevisiae compared to those of the control group, while in breast meats the significant difference was monitored after 6 d of incubation. It is concluded that dietary S. cerevisiae could improve the tenderness and oxidative stability of broiler meats.

  • The present study was conducted to evaluate the effects of black soldier fly larvae oil (BSFLO) from the black soldier fly larvae (BSFL) as a partial or total replacement of soybean oil (SBO) on growth performance, fatty acid (FA) profile, and meat quality of broiler chickens from 1 to 5 wk of age. A total of 210 male broiler chickens (Ross 308) at one-day of age were randomly allotted to 3 dietary treatments (10 replicates and 7 birds/group): a basal control diet (CON), the basal diet in which the SBO was replaced by 50% (50 BSFLO) or 100% (100 BSFLO) of BSFLO. The growth performance, physical measurements and chemical traits of leg meat, and sensory analysis of breast meat were not influenced by diets. However, the relative weight (g/kg) of gizzard of CON was significantly higher (14.85, 12.52, and 13.02 for CON, 50 BSFLO, and 100 BSFLO; p < 0.05) than that of other treatments. As expected, the FA profile of breast meat was affected by BSFLO inclusion. The proportion (%) of saturated fatty acid (SFA) was increased (27.16, 27.58, and 28.72 for CON, 50 BSFLO, and 100 BSFLO; p < 0.05) by BSFLO inclusion and the percentage (%) of MUFA was also increased (43.36, 44.58, and 48.55 for CON, 50 BSFLO, and 100 BSFLO; p < 0.01). On the contrary, the proportion (%) of PUFA was decreased (29.49, 27.84, and 22.74 for CON, 50 BSFLO, and 100 BSFLO; p < 0.01). In conclusion, the present study suggests that the replacement of BSFLO did not show an adverse effect on growth performance and it could be an ingredient as a dietary fat source for a broiler diet.

  • The present study was conducted to investigate the effects of dietary Eucommia ulmoides Oliver leaves(EUOL) on the growth performance and meat quality of broiler chicks. The dietary treatments consisted of the control diet(corn-soybean meal basal), and EUOL 2, 4, and 6% diets. The latter three diets were prepared by adding 2, 4, and 6% EUOL to the control diet. Ninety-six Arbor Acre male broiler chicks were randomly allotted to 16 pens; four pens per treatment and 6 birds per pen. The growth performance and carcass weight of broiler chicks fed EUOL diets were not significantly different(P>O.05) from the control birds. Also, the muscle color degrees(L*a*b *)in brolier chicks were similar to each other. The blood concentrations of protein, sugar and glutamic-pyruvic transarninase(GPT) were not different(P>O.05) between control and treatment groups. The blood total cholestrol content was significantly(P<0.05) decreased by the addition of EUOL. However, the addition of EUOL did not change the muscle components significantly. The bone hardness of broiler chicks fed EUOL was significantly(P<0.05) higher than that of control chicks.
