To avoid chick culling, meat production can be carried out with either dual-purpose hybrids, where both genders are used, or layer males. However, comparative in-depth studies are lacking. The growth and slaughter performance and the meat quality of 2 commercial dual-purpose hybrids (Lohmann Dual, LD; Novogen Dual, ND) and a layer hybrid (Lohmann Brown, LB) were compared with slow-growing broilers (Hubbard S757, HU), as used for organic production. The growth periods tested were 67, 84, and 126 D (the LB only). A total of 1,350 birds per hybrid were kept in 5 compartments of 20 m². In a subsample, the carcass and meat quality were analyzed. The average daily gains and feed intake were quite similar in the ND, LD, and HU and were lower in the LB. Across 67 D, the FCR (kg feed/kg gain) of the HU was 2.62 compared with 2.81 and 2.83 in the ND and LD, respectively. The FCR of the LB was much lower (3.61). The breast angle, an indicator of the keel bone’s prominence, was largest in the HU, similar to that of the ND and the LD, and smallest in the LB. The breast meat proportions were always larger in the HU than in the ND and the LD at 21, 18, and 17%, respectively, and smallest in the LB (15%). The breast meat from the dual-purpose hybrids was similar, or slightly superior, to the HU in water-holding capacity and shear force and slightly inferior in intramuscular fat content. The LB meat did not differ much from that of the other hybrids. Growth for 126 D improved the carcass quality in the LB. In conclusion, both dual-purpose hybrids were competitive with slow-growing broilers, whereas this was not the case for the layer cockerels.

为避免宰杀小鸡，可以使用两性混合使用的两用杂种或成年雄性进行肉类生产。但是，缺乏比较深入的研究。将两种商品化两用杂种（Lohmann Dual，LD ; Novogen Dual，ND）和分层杂种（Lohmann Brown，LB）与慢速生长的肉鸡（Hubbard S757，HU）进行比较。 ，用于有机生产。测试的生长期为67、84和126 D（仅LB）。每个杂种总共1,350只鸟被关在20 m ^2的5个隔间中。在一个子样本中，对car体和肉质进行了分析。ND，LD和HU的平均日增重和采食量非常相似，而LB则较低。整个67天，HU的FCR（千克饲料/千克增重）为2.62，而ND和LD分别为2.81和2.83。LB的FCR低得多（3.61）。胸角是龙骨突出的指标，在​​HU中最大，与ND和LD相似，而在LB中最小。HU的胸肉比例总是总是比ND和LD大，分别为21％，18％和17％，而LB中的最小比例（15％）。双重用途杂种的胸肉在持水能力和剪切力方面与HU相似，或稍优于HU，肌肉内脂肪含量稍逊于HU。LB肉与其他杂种的相差无几。126 D的生长改善了LB的car体质量。总之，两种用途的杂种都与生长缓慢的肉鸡竞争，而蛋鸡则并非如此。
