Maintenance of Reproductive Competency in Breeder Males
Published:September 15, 2014
Summary
The breeding performance is count upon the reproductive status of birds. In current poultry industry there are numerous challenges for reproductive competency. Many of these problems originated from upgrading body growth rate and egg production traits in poultry; which results weakening in reproductive characteristics. The continuous trend towards high yielding and fast growing birds ensuring tha...
yes reproductive fitness of male and female in broiler breeder is always the key of success. I recommend a grade nutrition with best ingredients with best management practices would replicate the performance as would be suggested by primary breeders for the genetic stocks available all over. If any herbal preparations supplementation would be helpful to maintain the reproductive fitness of both sexes then it would be very good. More data are essential to separate the effects of herbal preparations tested on large populations size
so that an economic impact of additional cost can be handled by all breeder farmers all over locations.
It is very good for future breeding operations if additives and supplements are restricted according to cost of additive and measurements of impact of additives to enhance the number of hatching eggs per female with at least 85% hatch ability are available all over.
For old breeder flocks, spiking of males can be good option to maintain the hatchability. Spiking will assist in maintaining the optimum ratio of female with good healthy male and the life-long fertility of the flock. Before spiking, walk through the flock and remove any unproductive males. Do not allow cull males to remain in the flock. The obvious culls will be easy to locate and remove. However over weight males that are not breeding will be harder to find. These males will normally have a full coat of new feathers and the fluff around the vent area will be intact. Males used to spike must weigh at least 8.5-9.0 lb (3860-4085g) and have been light stimulated for at least 3 weeks. Young, under weight males cannot compete with other adult males, resulting in starve-outs. Weigh the young spiking males separately from the original flock for at least 4 weeks subsequent to entering the flock to ensure they are eating properly.
What is the impact of hatch up on flock fertility? Here we see the presentation of some differences in normal Soren numbers an hear about a difference in androgens, but do not see actual flock results.
