“…The mortality rate in present study was in accordance with Misba and Aberra (2013) and Ali et al (2012), who observed that the increased rate of mortality with age. The major environmental factors responsible for increased rate of mortality during 9-to 18-weeks of age in present study was the prevalence of disease (coccidiosis).…”

The Normal Feathered local chicken (LL), Sasso-RIR (SRSR) and their F1-cross (LSR) chickens were hatched to evaluated for egg hatchability, growth performance, feed efficiency and survival rate. After 14-days of brooding, 150 chicks of each genotype were randomly selected and further replicated in to five pens in a deep litter grower house consisting of 30 chicks each in a completely randomized design, and evaluated for a period of 16-weeks. Hatchability of fertile eggs was highest for LL (80.0 %), intermediate for LSR (68.6%) and lowest for SRSR (55.9%) chickens. The body weight (BW) of chicks at 2-weeks of age was 80.0, 76.3 and 61.5 g/bird for SRSR, LSR, and LL, respectively, the latter being the lowest (p<0.05). The respective BW at 8-weeks of age was 732, 587 and 451 g while at 18-weeks it was 1877, 1379 and 1070 g/bird and different from each other (p<0.05). During 3- to 8-weeks and 9- to 18-weeks growth periods, the LL chickens were inferior (p< 0.05) in feed intake (29.7 and 66.9 g/d/bird) whereas the SRSR chickens were superior (p< 0.05) in body weight gain (15.5 and 16.3 g/d/bird) and feed conversion ratio (2.67 and 5.35 g feed/ g gain), respectively. The mortality rate of chicken was not affected by genotypes. It can be concluded that the exotic blood of Sasso-RIR chicken had played a significant role in upgrading the growth rate and market weight of the local Normal Feathered chicken without adverse effect on hatchability, feed efficiency, and survival rate.

“…Şimşek and Özhan (2015) reported that there was no difference in final BW of broilers reared in different flock sizes of 15 000, 25 000, and 35 000 chickens. In addition, Ali et al (2012), Rind et al (2004), and Türkyılmaz (2008 reported that the slaughter BWs of broilers reared in different group sizes were not statistically different. As in our study, the results of relevant studies on the effects of group size on body weights are not always in the same direction and as expected.…”

Abstract. This study aimed to determine the changes in the performance, welfare, and productivity level of broiler chickens reared at various group sizes (GS3000, GS4000, GS6000, and GS20 000) under intensive field conditions. The study was carried out according to a randomized block design with four different group sizes (GS) in three trials. Weekly body weights (BWs) were determined randomly in 150 individuals from each GS group. Feed intake (FI), feed conversion ratio (FCR), and European production efficiency factor (EPEF) were determined for each GS treatment. Body defects (footpad dermatitis, FPD, hock burn, HB, and the breast burn, BB) were measured randomly in 150 chickens (75 male and 75 female) from each group using a visual scoring system with a 0–3 scale. At 1 and 2 weeks of age, GS3000 broilers had similar BW to GS6000 and higher than GS4000 and GS20 000. However, this situation changed at 6 weeks of age and the male chickens in GS6000 became heavier than in GS3000, GS4000 and GS20 000 (P = 0.007). No differences in mean values of temperature, humidity, air velocity and litter moisture levels were observed among GS treatments. GS3000 and GS4000 chickens had significantly lower levels of FPD, HB, and BB than chickens reared in GS6000 and GS20 000 (P < 0.001). The EPEF values from highest to lowest were 425.8, 404.5, 358.8, and 354.0 in the GS6000 GS3000, GS4000, and GS20 000 groups, respectively. In conclusion, our study results showed that rearing in groups of 6000 broilers had both better performance and higher overall productivity than other groups but tended to show more severe body defects.

“…In the same research (Toghyani et al, 2010) compared wood shavings litter, rice hulls, paper rollers, sand, and no litter showed no different results in mortality. (Ali et al, 2012) using a stocking density of 0.186; 0.279 and 0.372 m 2 /bird rearing up to 2-6 months did not affect mortality, while this study used a density of 8, 12 and bird/m 2 (0.125; 0.083 and 0.063 m 2 / bird).…”

This research was aimed to determine the effect of different stocking density and different litter materials on the production performance of native chicken. Material of yhis study was 324-day old chick (DOC) native chickens, reared for 12 weeks. The DOC were randomly devided into 9 treatment groups include a combination of 3 stocking density (8, 12 and 16 bird/m2) and 3 litter materials (rice hulls, wood shavings and corncobs) in 3 replication. A completely randomized factorial design was an applied in the study then followed by Duncan's multiple range tests. The parameters observed were feed consumption (g/bird/12 weeks), body weight gain (g/bird), feed conversion ratio, and mortality (%). The results showed that feed consumption had affected by stocking density (p<0.05), but it had not affected by litter materials type. Feed consumption at densities of 8, 12 and 16 bird/m2 was 3890; 4020 and 4061 g/bird respectively. The highest feed consumption was obtained at a density of 16 bird/m2. Weight gain, feed conversion and mortality had not affected by stocking density and litter material. It can concluded that the body weight gain, feed intake, feed conversion ratio and mortality is same for stocking density 8,12 and 16 bird/m2 an d same for litter type of rice hulls, wood shaving and corncob.
