This research was carried out to investigate the fattening performance and slaughter and carcass characteristics of Hair goat and Saanen × Hair goat (G1) crossbred kids in different fattening systems. Thirty Hair goats and 30 Saanen × Hair goat (G1) crossbred singleton male kids 2.5-3 months old and weaned were used. The kids were fattened in three different systems: intensive, semi-intensive, and extensive. Marginal value analysis was applied to determine the optimum feeding periods of the kids. In order to determine the slaughter and carcass characteristics, all the kids fattened were taken to slaughter after determining their live weight at the end of the fattening. Live weight gains after the intensive, semi-intensive, and extensive fattening were 17.83 kg, 19.39 kg, and 18.29 kg in the Hair goat kids and 17.88 kg, 18.24 kg, and 17.32 kg in the Saanen × Hair goat (G1) crossbred kids, respectively. In the same order, the average concentrate feed consumed by kids for 1 kg live weight gain was 7.55 kg, 7.28 kg, 7.00 kg and 7.07 kg. Hot carcass weights after the intensive, semi-intensive, and extensive fattening were 13.58, 14.06, and 13.02 kg in the Hair goat kids and 14.21, 15.03, and 14.06 kg in the Saanen × Hair goat (G1) crossbred kids. The Saanen × Hair goat (G1) crossbred goats increased more in live weight than the Hair goat kids and the semi-intensive fattened goats increased more in live weight than the intensive and extensive fed goats. Moreover, the optimum fattening times generally varied between the groups, but not between genotypes within the group.

In this study, it was aimed to determine the fattening performance, slaughter and carcass characteristics of lambs of Eþme Kývýrcýðý (EKIV), Bursa Kývýrcýðý (BKIV), Çine Çaparý (CC) and Karya (KAR) sheeps. A total of 37 male lambs at the age of 3.5 months formed the animal material. Fattening period is 56 days. During slaughtering, head, feet, skin, liver, hot carcass weights were determined and hot carcass yield was calculated. Each carcass was cut out into 7 parts. The overall average of daily weight gain was 144.82 g. While the highest daily live weight gain was observed in the KAR, the CC had the lowest value. The total share of the rump, shoulders, back and arms are 57.65%, 66.85%, 65.80% and 67.12% for CC, EKIV, KAR and BKIV, respectively. The effect of the genotype on all the characteristics other than cooling loss is important. In terms of dressing percentage value, the ranking was CC, BKIV, KAR and EKIV from the highest to the lowest.

Abstract. The study was carried out to investigate the effects of two housing systems on the growth performance, carcass traits, and meat quality of growing rabbits during the terminal fattening period. The rabbits were lodged in conventional cages between 35 and 59 days of age (growing period). At this age, they were moved into two different housing systems until they were 87 days of age (fattening period). During the fattening period, 48 rabbits were housed in 12 wire cages (0.5×0.6×0.35 m) and 48 rabbits were housed in one open-air pasture pen (20×9 m). At 87 days, 12 rabbits per treatment were slaughtered and the carcass characteristics and meat quality were evaluated. During the fattening period, the rabbits reared in cages had significantly higher live weights (3 062 vs. 2 705 g), weight gains (45.9 vs. 34.2 g·d−1) and feed intakes (163.4 vs. 110.2 g·d−1) than those reared in pens. The rabbits in the open-air group had a lower percentage of dissectible fat (1.35 vs. 4.19 %), a higher proportion of hind part (34.9 vs. 33.1 %), and less hind leg muscle (79.3 vs. 81.9 %) than caged rabbits. The m. biceps femoris of the rabbits in the open-air group had a higher cooking loss (3.64 vs. 3.02 %), Warner-Bratzler Shear Force (4.26 vs. 3.29 kg·cm−2), and myoglobin concentration (0.41 vs. 0.32 mg·g−1) than caged rabbits. The housing system had no effect on the dressing out percentage, viscera proportion, and ultimate pH. Open-air housing system reduces the growth of rabbits and the fat content of carcasses and increases the redness colour of meat.
