The science of breeding chickens has revealed part of the mystery of how certain female animals are able to store sperm long-term. Droplets of fat transferred from female cells to . incubation egg weight, storage periods, chick weight and subsequent performance of different kinds of poultry [5,3]. Domestic poultry and waterfowl eggs generally lose 11 to 15% of their initial weight during incubation , although weight loss averages for various species can range from 10 to 23% . Fertility and hatchability.
Aseel, a famous chicken breed, has problems of low fertility that leads to poor hatchability. In commercial breeder setups, the hatchability issues are being addressed by fresh semen artificial insemination (AI). The success of AI mainly depends on semen quality and its life in female reproductive tract. Now a days, different antioxidants are being used to improve the semen : A. Jabbar, W. Abbass, A. Riaz, A. Sattar, M. Akram. In addition to molting, also nutritional status has been shown to influence the reproductive performance in term of semen quality, fertility, hatchability and body weight of hatched chicks. Vitamin E has received considerable attention in poultry as a feed additive (Khan, , Khan et al., , Khan et al., b).Cited by:

Only a small proportion of the pool of semen deposited in the vagina or cloaca is stored in the SST, which indicates sperm selection in the female reproductive tract.

To have good fertile breeders anf good hatchability you all can use this recipe Glenda L Heywood 1/2 gallon of wheat 1/8 cup of wheat germ (Pure not blended kind) mix good to coat the grains let stand over bight then mix and feed eacj bird 3 tbsp in feeders so both the male and females get 3 tbsp each This provides Vit E for fertility also you.

Short-term storage and pooling of chicken semen as related to fertility and hatchability Public DepositedAuthor: William Logan Wigle. SHORT-TERM STORAGE AND POOLING OF CHICKEN SEMEN AS RELATED TO FERTILITY AND HATCHABILITY I. INTRODUCTION Sincewhen Burrows and Quinn first reported a manual massage technique for obtaining semen from the male fowl, researchers have been interested in the in vitro storage of cock semen.
The utility of holding semen for extended periods for its. Short-term storage and pooling of chicken semen as related to fertility and hatchability. Liquid storage of semen at refrigerated temperatures for up to 6 h in turkeys and 24 h in chickens can result in fertility levels comparable to freshly inseminated by: The current study evaluated the impact of five egg storage durations and two temperature conditions on egg quality, fertility, hatchability and chick quality in a 6th generation heterozygous naked neck chickens.
Methodology: A total of hatching eggs were initially obtained from 45 weeks old flocks in five batches and weighed. Eggs (n= Storage of poultry semen. Methods of semen collection and artificial insemination (AI) in poultry, requirement for diluents, methods of liquid and frozen storage of avian semen and evaluation of spermatozoa after storage for fertilizing ability are reviewed.
Frozen storage of semen from non-domestic birds is also briefly discussed. Sperm motility in samples held at 15 or 5 C was similar to that of the unstored controls. The fertility of diluted chicken semen was highest (75%) after 6 hr of storage at 5 C.
Fertility levels (71 to 83%) of chicken semen held for 3 hr at 25, 15, or 5 C did not differ from the unstored by: Effect of the diluent components on the fertilizing capacity of chicken semen stored at 5 degrees C.
Sexton TJ, Fewlass TA. The major objective of this study was to assess the relationship of various components of the Beltsville Poultry Semen Extender (BPSE) to the maintenance of the fertilizing capacity of chicken semen stored at 5 degrees by: Semen is inexpensive to produce and is commonly available in many, if not most, homes and restaurants.
Despite all of these positive qualities, semen remains neglected as a food. This book. Dilution of low and viscous volume of avian semen is essential for handling and storage, and chicken semen typically requires a two to three-fold dilution.
Chicken and turkey semen begins to lose fertilizing ability when stored >1 hr. Liquid cold (4°C) storage of turkey and chicken semen can be used to transport semen and maintain spermatozoal viability for ~6–12 hr.
This short-term storage of semen is common in turkeys, while not as common in chickens. Further improvement would be possible by crossbreeding with the highly producing breeds like white with the locally used in backyard poultry which is low producer.
Fertility and hatchability are important parameters that should be studied before finalizing the cross breeding program for backyard poultry. This TABLE Effect Hours stored Ave. Range 4- 8 F. WILCOX of storage time of chicken semen on subsequent hatchability Fresh, untreated control No.

Freshwater and a saline solution were used as sperm activators. The semen samples were stored at 2–3°C and fertilized after 0, 6, 8, 12, 19, and 25 days of storage.
Fertilizing capacities of semen samples stored in the presence of antibiotics ( ± %). Successful application of this technique needs good quality semen that should be inseminated very close to the sperm storage tubules in the female to obtain the optimum fertility in chicken.
of color of semen. Sometimes, dilution of chicken semen may result in a significant decrease in the percentage of dead sperm in stored semen. Sperm motility from both undiluted and diluted chicken semen was the lowest when stored at 41°C compared to storage at 25, 15 or 5°C .
Moreover, there are reports that breed. Cross breeding in chicken results in higher hatchability, fertility, faster weight gain, disease resistance and low mortality in chickens. Hybrid vigor by cross breeding is extensively used in broiler production.
Line Breeding Line breeding is like inbreeding but involves breeding of birds less closely related. Therefore, the lowest frequency of fertility, hatchability of set eggs and hatchability of fertility eggs were recorded in broiler chickens over the age of 60 weeks and eggs weighing more than 69 gr.
The assessment of semen quality characteristics of poultry birds gives an excellent indicator of their reproductive potential and has been reported to be a major determinant of fertility and subsequent hatchability of eggs (Peters ). et al., According to Bratte and Ibe (), sperm concentration of 50x is adequate for good fertilityFile Size: 72KB.
Single preincubations of 6 and 12 h at 4 d of storage caused similar advances in embryo stage to the SPIDES treatment, but the hatchability was worse than in the untreated controls, suggesting small multiple preincubations during storage have a greater benefit than a single incubation performed on d 4 of by: Hatchability showed a dramatic drop for eggs set after 7 days of storage.
In addition, it was observed that as the period of storage increased, the hatchability of fertile and total eggs set decreased.
Egg weight had significant effect on hatchability of total eggs (Pfertility and hatchability of fertile eggs (PFile Size: KB.Excerpt.
It is recognized that cool egg storage for 8 d or longer, commonly employed in broiler parent and commercial layer production, reduces hatchability. In this study, we investigated the efficacy of short periods of incubation during egg storage (SPIDES) in the restoration of hatchability of broiler hatching eggs stored for 21 d.
