Hazelnut husks and some other litter materials were compared for litter properties and their effects on broiler performance. 2. A total of 750 1-d-old broiler chicks were weighed and assigned at random to 1 of 5 treatments, with each treatment replicated 3 times. 3. The treatments were wood shavings (control), wheat stalks, rice hulls, hazelnut husks, and a mixture of 50% rice hulls and 50% hazelnut husks. 4. Although hazelnut husks were associated with lower body weights at 49 d of age, food efficiency mortality, carcase yield, breast blisters and production index were similar to birds on wood shavings. Hazelnut husks had the highest litter moisture. 5. The results show that hazelnut husks alone and when mixed with rice hulls are a potential alternative litter material for broiler production.

This study was conducted to assess the impact of genotype and outdoor access (and gender when appropriate) on growth rate and carcass yield. 2. One slow-growing genotype (Bronze; B, n = 129), a commercial fast-growing genotype (Hybrid; H, n = 186) and a medium-growing genotype (crosses; H x B, n = 78) were housed (straight-run) for 21 weeks of age. Each genotype was assigned to 3 pens of 20-23 birds each and raised in indoor floor pens in a curtain-sided house with ventilation fans; the B, H and H x B genotypes were also assigned to 3, 4 and 2 floor pens (2 m(2) approximately) with outdoor access (during daylight hours), respectively. All animals were fed ad libitum a commercial diet and birds were commercially processed. After reaching the commercial live weight at 17 and 21 weeks of age, 4 birds (two females and two males) per replicate were slaughtered to determine the yields of carcass, breast, and thigh, abdominal fat and edible inner organs. Gastrointestinal tract characteristics such as length and weight of whole gut were analysed. 3. No significant interaction between genotype and housing systems was observed. Significant differences were found for all traits among genotypes. The live weight was higher in H and H x B genotypes from 7 to 15 weeks and from 7 to 21 weeks of age compared to B genotype, respectively. The live weight of H genotype was higher than that of H x B genotype from 15 to 21 weeks of age. The carcass weight and yield, and the relative weights of the edible inner organs and whole gut, and the relative length of whole gut were significantly affected by genotype and sex of birds. Differences in growth performance, relative weight of breast meat, wings or thighs between birds raised on barn or free-range were negligible. In conclusion, while the development in growth performances was related to strain, the traits at slaughter were related to both strain and sex, and were unaffected by housing system.

The males of the dam (A1) and sire (B1) line were grouped according to their BW after selection at the 6 th and 12 th weeks of age. In the sire lines, the heaviest males at six weeks of age were selected (300), and the selected males were divided into three groups in terms of BW as average (B11: 100 males), high (B12: 100 males), and the highest (B13: 100 males). In the dam lines, the selected males were divided into three groups as an average (A11: 100 males), low (A12: 100 males), and high BW (A13: 100 males). In the dam line, offsprings of males with average and high BW had the highest BW at 42 days of age compared to the low BW group (p<0.05). However, there was no statistically significant difference in BW between the BW groups in the offsprings of the sire line. Offsprings of dam line males with average and higher than average BW had better FCR values. However, there was no significant change in FCR between the offsprings of the sire line BW groups. As a result, it is thought that by preserving the variation at a certain level in future generations, a significant improvement can be achieved in the BW and FCR by selecting heavier males.

The relationships between feather score and eggproduction and feed consumption were evaluated for thetotal study population and by live weights and eggshellcolor of genotypes. Animal material was comprised of 360layers (72 layers per genotype). Feather scores were obtainedby observation at 6 locations (head, neck, breast, back,wing and tail) at 30, 40, 50, 60 and 72 weeks. Egg produc-tion was calculated on a dail y basis, and feed consumptionand egg weight were calculated on a weekly basis. Correla-tions were identified between feather score and egg produc-tion, feed consumption and egg weight among the overallstudy population and according to live weight and eggshell color.Significant differences among genotypes were found infeather scores at different body parts (P < 0.05, P < 0.01).A significant correlation was found between feather scoreand egg produc...

The chicks were hatched from eggs collected from 35-week-old hens of pure line broiler flocks. Data were collected at hatch, and at 1, 2, 4, 6, 8, 12, and 20 weeks old Thirty males and 30 females were evaluated for each line. The early feathering genotypes (A2, B1 and B2) had longer primary feathers until they were six weeks old. They also had higher under-wing and rectal temperatures and higher live weight compared with the late-feathering lines (A1 and A3) at one and two weeks old. The males were heavier than females at all ages. However, under-wing and rectal temperatures were similar in males and females at all ages. A positive correlation was observed between the length of primary feath...

In this study, live weight (LW), carcass weight and ratio (CW and CR), breast weight and ratio (BW and BR), abdominal fat weight and ratio (AFW and AFR), morphometric traits such as breast width, length and index (BWD, BL and BI) were investigated in broiler pure lines. The research material consisted of 3 dam (A1, A2 and A3) and 2 sire (B1, B2) pure lines of 42 days of age. LW, CW, BW, AFW, AFR, BR, BL, BWD and BI values were different between the two lines (p<0.05). LW, CW, BW and BI were higher in sire lines. The relationship between breast weight and index were also higher in sire and dam lines than the relationships between breast width and length separately (in sire lines: BWD: 0.73; BL: 0.79; BI: 0.79, in dam lines: BWD: 0.79; BL: 0.74; BI: 0.84). In addition, high r 2 values were determined in regression equations for BW estimation in dam and sire lines (0.836 and 0.857, respectively). Because of the significant correlations between breast yield and its morphometric traits, it is seen that more feasible, ease of measurement, protection of breeding resources and welfare. It is thought that the use of breast index which shows a higher correlation compared to these traits will increase selection efficiency instead of using breast width and length separately.

One hundred twenty chicks of each strain were raised in each production system. Chicks were raised in indoor pens at a density of 10 chicks per m2. From day 29 until slaughter at 84 days of age, chicks in the free-range system were given outdoor access through doors that were open between 8.00 - 17.00 hours. The study found live weight, feed efficiency, and mortality were significantly affected by strain. However, no significant differences were found between the production systems. Outdoor access varied significantly among strains, with the commercial high-growth and medium-growth crossbred strains making less use of outdoor areas. In terms of performance traits, none of the strains showed any significant differences in performance between the indoor and free-ran...

Production system had a significant effect on live weight until 14 wk of age. Live weights were similar between free‐range and indoor production systems at 16 (1,150 g vs. 1,152 g) and 18 (1,196 g vs. 1,203 g) wk of age. Guinea fowl reared in a free‐range system consumed more feed (7,693 g vs. 6,983 g), and guinea fowl reared in a barn had better feed conversion ratio (5.80 vs. 6.43) (P < 0.05). Production system, gender, and slaughter age did not affect the dressing percentage. Guinea fowl reared in a free‐range system had significantly less abdominal fat (P < 0.05).

This study investigated the effect of incubation type and production system on geese growth traits. 2. A total of 216 geese that were either naturally (114) or artificially (102) hatched and reared in intensive or free-range production systems (4 replicates each) until 18 weeks of age. 3. Weights of naturally hatched goslings were significantly higher than artificially hatched goslings at 2 weeks (644 g vs. 536 g); however, weights of artificially hatched goslings were significantly higher than naturally hatched goslings at both 6 weeks (3245 g vs. 3010 g) and 18 weeks (5212 g vs. 4353 g). 4. Artificially hatched goslings had better feed conversion ratios than naturally hatched goslings (6.21 vs. 6.46 at 18 weeks). Feed consumption of naturally hatched geese was found higher in first 4 weeks when compared to artificially hatched geese and artificially hatched geese consumed more feed than naturally hatched geese after 8 weeks. 5. Production system had insignificant effects on feed consumption, feed conversion ratios, viability and mutilation rates. 6. Slipped wings were more frequent in naturally hatched goslings than artificially hatched goslings (8.32% vs. 1.68% at 6 weeks; 23.84% vs. 5.12% between 7-18 weeks) and in freerange production when compared to intensive production (17.88% vs. 11.08% over the course of the production period). Running title: Growth traits of geese 3 7. The study results indicate that both artificially and naturally hatched goslings can be reared in free-range production systems without any loss in performance and in deference to animal welfare.
