| ABSTRACT This study was conducted to compare edible giblets weight, tibial bone mineral density (BMD), and bone mineral content (BMC) of two slow-growing broiler genotypes (Hubbard S757; S757 and Hubbard Grey Barred JA; GB-JA) reared with outdoor access, and to determine the relationship between these variables. Day-old chicks (straight-run) of the genotypes S757 (n=120) and GB-JA (n=120) were housed for 98 days. Each genotype was assigned to six pens of 20 birds each. Birds were reared in indoor floor pens and moving shelters with outdoor access (during daylight hours). Absolute body (BW), heart (HW), spleen (SW), liver (LW), gizzard (GW), and abdominal fat pad (AFW) weights of the genotype S757 and male birds were statistically higher than that of the... |

| ABSTRACT The present study was conducted to investigate the effect of hatching egg weight of broiler parent stocks on hatching results, chick performance, carcass characteristics, internal organ weights and some blood stress parameters. Eggs were divided into 3 egg weight groups (55.0 to 60.0 g (light), 60.1 to 65.0 g (medium) and 65.1 to 70.0 g (heavy)) for the experiments. After incubation, mixed-gender broiler chicks from the hatcher were placed into 27 grower pens (2x1 m) with 9 replications for 3 weight groups by using randomized block design. Each pen had 25 broiler chicks. Therefore, 225 chicks were used for each group and 675 chicks in total. The experiment was designed with nine replicates. Chi-square test, variance analysis test and Duncan... |

| ABSTRACT The objective of this study was to determine the effects of eggshell color of guinea fowl (Numida meleagris) eggs on eggshell quality and hatchery results. The highest mean grey value (MGV), integrated density (ID), lightness (L*) and Hue angle (H*) values were obtained in eggs with lighter eggshell color. The effects of color difference (DE*) value levels on egg characteristics were evaluated. Eggshell color presented different (p<0.01) MGV, ID, L*, redness (a*), yellowness (b*), H* and Chroma (C*) values. Eggs with lighter color presented thicker eggshells and lower egg weight loss on day 25 of incubation (p<0.05) compared with intermediate and darker eggs. Eggshell color did not have any significant effect on fertility and hatchability... |
