Abstract:To clarify the impact of the dwarf gene(dw) on the production performance of Jilin Luhu chickens, this study compared the growth performance of two strains(normal and dwarf) of Jilin Luhu chickens, with measurements and analyses conducted in aspects such as growth performance, feed-meat ratio, and feed-egg ratio. The results showed that compared with the normal strain of Jilin Luhu chickens, the average weight of adult roosters in the dwarf strain was 70.59% of that in the normal strain, with a significant difference (P<0.05); the feed-egg ratio was significantly lower than that of the normal strain; and the dwarf strain of Jilin Luhu chickens had a high uniformity. Therefore, considering the characteristics of good uniformity and feed-saving of the dwarf strain of Jilin Luhu chickens, it can be used in the production of high-quality processed broilers and as a maternal line in crossbreeding programs.
