Use of a sperm analyzer for evaluating broiler breeder males. 2. Selection of young broiler breeder roosters for the sperm quality index increases fertile egg production.
Previous research has shown that the sperm quality index (SQI) of rooster semen is indicative of overall semen quality. The objectives of the present experiments were to determine the correlation of the SQI with semen characteristics and fertility and to determine if selection of young males for the SQI would improve fertility. In Experiment 1 semen was collected from 35 Peterson males and was ...
متن کاملUse of a Sperm Analyzer for Evaluating Broiler Breeder Males. 1. Effects of Altering Sperm Quality and Quantity on the Sperm Motility Index1,2
A new instrument for assessing mammalian semen attributes, the Sperm Quality Analyzer, was evaluated as a potential tool for determining rooster sperm quality. The Sperm Quality Analyzer measures the “activity” of sperm in a semen sample as the sperm motility index (SMI). The SMI is defined as the number and amplitude of deflections in a light path per second as a result of sperm movement wit...
متن کاملSimilarities and differences between the sperm quality index and sperm mobility index of broiler breeder semen.
The sperm quality index (SQI) and sperm mobility index (SMI) both predict sperm motility. Previous research was conducted comparing the SMI with the SQI; however, semen was diluted improperly for the SQI (40-fold). For an accurate comparison, semen must be diluted 10-fold for the SQI. Therefore, the overall objective of this study, utilizing 4 experiments, was to examine the relationship of the...
متن کاملComparative study of semen traits and histomorphometric features of testes of broiler breeder males with different phenotypic traits
Fertility reduction due to sub-fertile males is a major concern in breeder flocks. Phenotypic traits of broiler breeder males and their relationships with fertility can be used as reliable indicators for identification and removal of sub-fertile males from the breeder flocks. This study was conducted to investigate semen traits (semen volume, sperm motility, sperm viability and sperm count) and...
متن کاملthe effect of d-aspartic acid on sperm quality of broiler breeder roosters
the aim of this study was to evaluate the effect of d-aspartic acid on semen characteristics of ross 308 roosters. thirty 60-wk-old ross 308 roosters were randomly assigned into 6 groups and individually caged. all groups fed the same basal diet and orally administered with different levels of d-aspartic acid: 0(a-0), 40 (a-40), 80 (a-80), 120 (a-120), 160 (a-160), and 200 (a-200) mg/kg bw per ...
