It is demonstrated that the Sperm Mobility Test can be used for on-farm evaluation of semen quality of toms in commercial flocks and that sperm mobility influences fertility and sire fitness.

Figures and Tables from this paper

Field testing the influence of sperm competition based on sperm mobility in breeder turkey toms

It appears that sperm mobility is a trait that influences sperm competition among toms under field conditions where sperm numbers inseminated from individual toms are not controlled or constant and that toms with low sperm mobility produce few offspring.

The effect of sperm mobility phenotype on fertility persistence in layer and broiler hens

Domestic fowl were studied to identify accurate predictors of potential fertility in two lines of broiler breeder males along with fertility persistency in layer and broiler hens and revealed a significant age*line interaction for semen volume, concentration, and mobility.

Sperm mobility phenotype not determined by sperm quality index.

It is concluded that variation in SQI scores was enigmatic because sperm concentration was controlled in the authors' experiments, sperm viability was invariant, and motile concentration did not differ among roosters characterized by extreme SQI Scores.

Utilisation of a sperm quality analyser to evaluate sperm quantity and quality of turkey breeders

Results indicate that the SQA can respond to differences in turkey sperm concentration, viability, and motility using in vitro analyses.

Assessment of Semen Characteristics Among Three Phenotypes of Chicken Raised in Akko, Gombe State of Nigeria

It is suggested that there are large variations present in semen characteristics of different phenotypes of cocks; White feathered strain is likely have better semen characteristics compared to Red and Black feathered strains and can potentially be used in artificial insemination (AI) for chicken production and improvement.

THE EFFECT OF USING COMMERCIAL PROBIOTIC ON THE QUANTITY AND QUALITY OF NATIVE COCKERELS ' SEMEN

This study was conducted to study the effect of using probiotic on the quantity and quality of the native cockerel semen productions. The duration of this study took about 4 weeks. Fifteen cocks were

Semen characteristics and artificial insemination in rockhopper penguins (Eudyptes chrysocome chrysocome).

Semen collection and characterization was performed on 14 male rockhopper penguins and paternity testing was performed using 12 microsatellite loci, but unfortunately due to insufficient variability, the paternity of the chick and two embryos could not be determined.

The effect of sialic acid on the success of poultry spermatozoa cryopreservation

The results demonstrate that the optimal SA incubation conditions for improved fertility with frozen/thawed sperm occurs with 160 μg/ mL SA prefreeze for turkey and 120 μg/mL SA pre- freeze for chicken (P<0.05).

Adaptation of the Sperm Mobility Test for Identification of Turkey Toms with Low Fertilizing Potential

This study attempted to determine if a reliable laboratory method for the analysis of turkey sperm mobility could be successfully modified for commercial field use in the turkey industry and concluded that the SMT is adaptable for on-farm use for the selection of potential sires.

Assessment of ejaculate quality and sperm characteristics in turkeys: sperm mobility phenotype is independent of time.

Because sperm mobility phenotype remained consistent through time, the Sperm Mobility Test provides a potentially important tool for selecting semen donors in turkeys.

Prospective approaches to avoid flock fertility problems: predictive assessment of sperm function traits in poultry.

Why it is important to evaluate males as individuals and how advances made in understanding and measurement of sperm function can be used to improve reproductive efficiency in poultry are discussed.

Turkey sperm mobility influences paternity in the context of competitive fertilization.

This is the first illustration of a measurable sperm trait predictive of paternity success in a competitive fertilization trial in turkeys, a species that is predominately reproduced by artificial insemination of multiple-sire pools.

Sperm mobility: A primary determinant of fertility in the domestic fowl (Gallus domesticus).

It is concluded that sperm mobility is a primary determinant of fertility in the fowl and the hypothesis that vaginal immunoglobulins constitute an immunological barrier to sperm transport was rejected.

Semen donor selection by in vitro sperm mobility increases fertility and semen storage in the turkey hen.

Sperm-mobility differences between toms (detected by means of the SMT) influenced sperm storage, as indicated by the number of sperm in the PL and by the percentage of fertile eggs produced.

Sperm mobility: a quantitative trait of the domestic fowl (Gallus domesticus).

Repeated-measure analysis of males categorized by phenotype demonstrated that average and high sperm mobility phenotypes were distinct and independent of time.

Sperm mobility determines the outcome of sperm competition in the domestic fowl

There was a significant positive relationship between the proportion of offspring fathered by the high–mobility male and the ratio of mobility scores between males (p < 0.05), and in the competitive situation high–Mobility males were disproportionately successful in fertilizing eggs compared with average-mobility males.

Objective measurement of sperm motility based upon sperm penetration of Accudenz.

The assay described has potential for: 1) selecting males based on sperm motility, and 2) standardizing the measurement of poultry sperm motilty.

Paternity Efficiency in Turkey Differs Extensively After Heterospermic Insemination

It was demonstrated that relatively few toms sired a high percentage of the progeny and the semen parameters evaluated, some of which are used routinely by the turkey industry, were not good at predicting paternity.
