Effect of Frequency of Ejaculation on Semen Characteristics in Two Breeds of Turkeys (Meleagris gallopavo) Raised in a Tropical Environment

01 Apr 2005-International Journal of Poultry Science-Vol. 4, Iss: 4, pp 217-221

TL;DR: Semen collection in turkeys is more favourable when harvested once per week since semen concentration declines progressively with increase in the ejaculation frequency.

AbstractA study was carried out at the Abubakar Tafawa Balewa University Farm, Bauchi (February - May, 2002) to investigate the effect of frequency of ejaculation (once, twice and thrice per week) on semen traits in exotic and local turkeys. The results showed that ejaculate volume, live spermatozoa, abnormal spermatozoa, sperm concentration and total sperm per ejaculate were significantly (P<0.05) higher in exotic than local turkeys, values being 0.32±0.02 vs 0.17±0.02ml, 83.83±1.33 vs 80.67±1.33%, 11.19±0.73 vs 13.61±0.73%, 4.66±70.73 vs 2.81±74.93 x 10 and 97.72±9.86 vs 50.81±10.45 x 10 . It was also shown that 9 9 sperm concentration was the only variable significantly affected (P<0.05) by frequency of ejaculation. The interaction of breeds and frequency of ejaculation also favoured (P<0.05) the exotic breed at lower frequency of ejaculation. Semen collection in turkeys is more favourable when harvested once per week since semen concentration declines progressively with increase in the ejaculation frequency. The exotic have superior genetic make-up than the local turkeys in terms of their reproductive potential.

TL;DR: Sperm concentration was better in the morning time, while the values for sperm viability and plasma membrane integrity were higher in the semen collected at evening time, and contrasted parameters of quality.
Abstract: The Indian Red Jungle Fowl is a wild native gallus subspecies of Southern Asia. Semen has never been studied in this species. In order to better know the male reproductive capacities, experiments were conducted to study the semen characteristics, impact of ejaculate collection frequencies, and timing of collection on sperm quality parameters. Mean sperm concentration 800 million/mL, total sperm per ejaculate (0.015 billion), motility (63.5 %), live/total sperm (92.4 %), intact acrosome (75.5 %), and plasma membrane integrity (89.2 %) were recorded. Percentage of abnormal sperm (head, mid-piece, and tail) was 8.1 % and recovered mainly mid-piece abnormalities. The motile sperm percentage was positively correlated with intact acrosomes (r = 0.34) and plasma membrane integrity (r = 0.41). Total sperm per ejaculate (billion) was maximum at 72 h of collection followed by 24 and 48 h of collection. Daily and weekly sperm production (billion) was found maximum at 24 h of collection compared to 12, 48, and 72 h of collection. Sperm motility was higher at 24, 48, and 72 h of collection compared to 12 h of collection, but the number of live sperm were higher at 12 h of collection compared to 24, 48, and 72 h. Sperm concentration was better in the morning time, while the values for sperm viability and plasma membrane integrity were higher in the semen collected at evening time. In conclusion, the Indian Red Jungle Fowl shows a semen production quantitatively relatively low for the species as compared to domestic chicken and contrasted parameters of quality. The semen production is affected by the frequency of collection with an optimum for a daily collection preferentially held in the evening period. These results may now be used for artificial insemination and conservation program.

TL;DR: The protocols and hormones used for estrus synchronization to facilitate artificial insemination are presented, and the macroscopic and microscopic characteristics of semen are discussed.
Abstract: L’insemination artificielle est une technique de fecondation sans intervention directe du mâle, par depot de sperme dans les voies genitales de la femelle. Elle est utilisee pour la diffusion du progres genetique et permet a l’eleveur de gagner du temps dans l’exploitation. Elle est egalement un outil de controle des pathologies veneriennes de contact. Cet article fait le point des travaux realises en Afrique de l’Ouest sur l’insemination artificielle. Apres la presentation des techniques de collecte de sperme par espece, les caracteristiques macroscopiques et microscopiques du sperme sont abordees. Les dilueurs utilises pour la cryoconservation et la conservation a l’etat frais sont rapportes. Les protocoles et hormones utilises pour la synchronisation des chaleurs pour faciliter l’insemination artificielle sont ensuite presentes. Enfin, les resultats des inseminations artificielles sont presentes. L’insemination artificielle est plus pratiquee en elevage bovin. Les travaux realises sur les autres especes se sont limites aux caracteristiques du sperme. Pour une meilleure utilisation de cet outil, des efforts doivent etre poursuivis pour la production des doses de qualite chez les autres especes animales notamment les porcs et les volailles. Mots cles : Insemination artificielle, synchronisation de chaleurs, semence animale, dilueur English Title: State of animal artificial insemination in West African countries. A review Artificial insemination is a fertilization technique without direct male intervention, by depositing semen in the female's genital tract. It is used for the dissemination of genetic material and saves the farmer time on the farm. It is also use to control livestock veneral and contact diseases. After the presentation of semen collection techniques by species, the macroscopic and microscopic characteristics of semen are discussed. Extenders used for cryopreservation and fresh preservation are reported. The protocols and hormones used for estrus synchronization to facilitate artificial insemination are then presented. Finally, the results of artificial insemination are presented. Artificial insemination is more practiced in cattle breeding. Work on other species was limited to sperm characteristics. In order to make better use of this tool, efforts must be continued for the production of quality doses in other animal species including pigs and poultry.
