Abstract

The aim of this research is to a determined the breeding value of native roosters based on macroscopic and microscopic semen. Ten native roosters were used in this research. Complete individual cage, semen collection tools and substance, macroscopic and microscopic tools, and substance were used in this research. The native rooster was rested for 2 weeks. Massage techniques were used for semen collection. Parameters observed were volume, pH, color, viscosity, smell, sperm concentration, and sperm livability. The semen collection was repeated 5 times. One-way analysis of variances was used for data analysis with the tools SPSS 16. The breeding value was estimated based on primary traits of semen and calculated for each rooster to make a rank. The results showed that significant parameters (P<0,05) are semen volume and sperm concentration, while the non-significant parameters (P?0,05) are pH semen and sperm livability. Semen color is yellowish-white, semen viscosity is medium-viscous and smell is spermin. The results of breeding value rank are rooster numbers 6, 7, 5, 3, 2, 4, 8, 9, 10, and 1. The conclusion is the breeding value of Native roosters is varied. The recommendation is Native chicken breeding need to apply selection used breeding value based on semen quality.

Abstract

This study aimed to determine the effect of breed and season on the semen quality of AI bulls. The material used was n= 78,648 records of ejaculated semen from 85 Limousine and 88 Simmental bulls collected between period 2010 and 2020. Semen qualities evaluated in the study were: ejaculate vol-ume (Vol), pH, individual sperm motility (ISM), sperm concentration (SC), and post-thawing motility (PTM). The data was analyzed by using a MIXED model with breeds and seasons as fixed effects and animals as random effects. The seasons were significant (p<0,05) on Vol, ISM, SC, and PTM, then the interaction between season and breed was affected on Vol, SC, and PTM. Simmental bulls generally showed better semen qualities than Limousine bulls. Further, the same result showed significant differ-ences in each season. The Vol, ISM, SC, and PTM of Simmental were 6.48 ± 1.26, 64.22 ± 1.16, 1,108 ± 0.46, and 42.19 ± 0.38, respectively. The increase of Vol and SC in the humid season has not propor-tionally affected ISM.
