Impact of different mating sex ratios on reproductive efficiency of silver pheasant Lophura nycthemera (Galliformes, Phasianidae)

Impact of different mating sex ratios on reproductive efficiency of silver pheasant Lophura... The present study was conducted to evaluate the impact of different mating ratios (male-female) on egg production, egg fertilization %, egg hatching % and courtship behavior in Silver Pheasant Lophura nycthemera at three stations for a period of 16 weeks. The birds were kept in four groups with following malefemale ratios: Group-A (1:2), Group-B (1:3), Group-C (1:4) and Group-D (1:5). The results showed that Group-B (1:3) ratio has significant effect on mean number of eggs (1.75 ± 0.15), Group-C (1:4) on weight of eggs (93.22 ± 5.02), Group-C (1:4) and Group-D (1:5) on egg fertilization and hatching % while Group-B (1:3), Group-C (1:4) and Group-D (1:5) on time spent in mating. The feed consumed and feed conversion ratio was significant in Group-D (1:5). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Ecology Springer Journals

Abstract

The present study was conducted to evaluate the impact of different mating ratios (male-female) on egg production, egg fertilization %, egg hatching % and courtship behavior in Silver Pheasant Lophura nycthemera at three stations for a period of 16 weeks. The birds were kept in four groups with following malefemale ratios: Group-A (1:2), Group-B (1:3), Group-C (1:4) and Group-D (1:5). The results showed that Group-B (1:3) ratio has significant effect on mean number of eggs (1.75 ± 0.15), Group-C (1:4) on weight of eggs (93.22 ± 5.02), Group-C (1:4) and Group-D (1:5) on egg fertilization and hatching % while Group-B (1:3), Group-C (1:4) and Group-D (1:5) on time spent in mating. The feed consumed and feed conversion ratio was significant in Group-D (1:5).
