충남 논산에 위치한 (주)우성양행은 동물용의약품 분야에서 탑티어에 속하는 기업이다. 모기업인 우성사료와는 축산업분야에서 동반자적 관계를 유지하면서 높은 성장도 이뤄냈다. 우성양행에서 생산관리를 총괄하는 나기선 상무이사는 "동물의약품 분야에서 매출액 기준 10위권인 우성양행은 첨가제, 의약품 쪽으로는 3위권이고, 팜세이프, 농장 소독 등 농장 청결제 분야에서는 선도를 달리고 있다"고 밝혔다. 단순히 시장점유율만 높은 것이 아니다. 철저한 제조과정 속에 6년 동안 단 한차례의 사고도 발생하지 않았고 농림축산검역본부의 GMP(동물용의약품 등 제조 검사시설 및 품질관리기준)를 준수하며 적합한 제품을 생산해 오고 있다. 동물의약품 제조분에서 시장점유율, 안전분야 모두 선두에 서 있는 우성양행이 어떠한 안전관리와 경영활동을 펼치고 있는 이야기를 들어봤다.

Sex identification in day-old chicks is essential in the poultry industry. Currently, the feather-sexing using a sex-linked inheritance is a chick sexing method used extensively in the poultry industry. For chicks produced by feather-sexing, all females are early-feathering (EF) chicks and all males are late-feathering (LF) chicks. Therefore, investigating the effects of EF and LF phenotypes on production traits of chickens is critical. The purpose of this study was to analyze and compare the production performance between EF and LF chickens in Korean native commercial chickens. The results showed that the survival rate of the EF chickens was significantly higher than that of the LF chickens, from hatching to 12 weeks of age (P<0.05), with the highest difference observed in females. However, no significant difference was observed in body weight between the EF and LF chickens at almost all ages. In addition, no significant difference was observed between in feed utility, such as average daily feed intake and feed conversion ratio, between the EF and LF groups. In conclusion, although the survival rate of early-feathering chickens was superior to that of late-feathering chickens, no significant difference was observed in growth performance and feed utility among Korean native chickens. The results suggest that production capacity is not influenced by feathering type in the establishment of a breeder structure and production system for feather-sexing Korean native chickens, which is valuable for the practical application of feather-sexing in the poultry industry.
