Maintaining Fertility in Broiler Breeders

An excellent and detailed examination - congratulations Dr. Nipane.
I would comment only that the careful management of male and female maturity during the rearing period will reduce many problems and ensure a successful production period. Males must be more mature than the females in order to avoid male rejection in the breeding house which results in the males losing their aggresiveness (social castration). Additionally I believe the male should be mating before the first eggs are laid - and this will not happen when a mature hen is coupled with a less mature male.

The topic - Fertility in Broiler Breeders is precisely elucidated by Dr. S. Nipane. The point well supplemented by Mr. Stewart McLean - Male must be much mature than the Female would be more challenging to manage but would definitely generate better result.

An excellent article about Maintaining Fertility in Broiler, scientific as well as practical. It will provide a great help to farm managers.

Dear sir,

Congratulations, very good article about Maintaining Fertility in Broiler 

This is the best I have ever read about fertility... Congratulations.

Dear Dr.Nipane,
Informative article about Maintaining Fertility in Broiler. Article speaks about the careful study you have conducted. This article will be very much useful for the farm managers. Once again thanks for providing minute details.

Dr Nipane,

your article on fertility in broiler is very informative.
Thanks.

Dr Nipane,

excellent article about Maintaining Fertility in Broiler; even infection of the foot (bumble foot) also prevents the male from mating, also a cause of reduced fertility.

This is a good article about Maintaining Fertility in Broiler. Males should never exceed 4750gm during production phase. Over weight male be culled regularly. Maintain male to female 10% upto 32 weeks then you may reduce depending on the aggresiveness of male. Extra aggressive male should keep separately and mixed late in life. Feed may be offered 125gm of 12% Protein and 2700 Kcal energy with low Ca level. If possible fish meal and wheat base feed should be made. Spiking should be done at the age of 40 - 42 weeks (3%). Intraspiking is also another tool which can be applied troughout production cycle.

Excellent, comprehensive, critical and suggestive: these are my descriptions of Dr. Nipane’s analytical article under review. This is more than enough professional submission from the stakeholder to men on the field to rumenate. Exposure, of course has been made of the importance of male breeder to its female counterpart in the reproduction cycle. It is hoped, however that breeder production managers would avail themselves of this ample insight to upgrade their flocks management for maximum profit. Congratulations doc!

I commend Dr. Habib-ur-Rahman for giving few but very essential and practical pointers to farm managers.

Thanks. A good & comprehensive article. Balanced ration and body weight management keep the results excellent.

Hi,

It was very interesting to read your article where you mentioned all the key points related to semen and insemination. The success of artificial insemination is directly dependent on the semen quality and its fertilizing capacity. For the decades, the sperm quality analysis like per cent motility, live-dead, morphological examinations of spermatozoa and dye reduction test were the commonly used techniques to assess the potential fertility of spermatozoa. However, there exists limitation in application of these sperm quality techniques due to the poor correlation between the test parameters and resultant fertility status of the laid eggs by inseminated birds. Methods employed for measuring fertility in samples of egg from commercial turkey flocks are time consuming and are of limited quantitative value. A faster and more reliable quantitative analysis of flock breeding efficiency can be achieved by estimating the number of spermatozoa, which interact with the egg in the infundibulum.
Because, therea linear relationship between parameters of sperm quality and inner perivitelline layer (IPVL) holes.

So, we should tyake all the measures to have better sperm-egg interaction. This can be achieved if the breeders birds both males and females are good reserve of selenium in their body which will help to get more number of sperms penetrating the IVPL and hence better fertility and hatchability.

Valuable article in simple way. Great

Breeder farms will go along way to benefit from this information

A good and nice effort , very informative in many ways
