“…The average semen volume obtained in current study was 0.22±0.04 ml which was within range as obtained by other researchers. The reason for the differences between the fresh semen values can be determined by factors such as the individual's age, breed, stripping frequency, nutrition, light, temperature, and genetics, all of which have an effect on turkeys (Turkoglu et al, 2005;Bakst and Dymond, 2015). Akcay et al, (2006) found sperm concentrations of 5.1±1.12 x10 9 sp/ml in their study, Ilgaz and Tekin (1990) found it to be 5.03±0.34x10 9 sp/ml.…”

This study was conducted to develop long-term storage methods for turkey semen using different extenders. During the study, the massage method was used twice a week to collect the semen from five turkeys, a total of 44 times. The collected fresh semen's average ejaculate quantity, sperm concentration, motility and vitality values were determined as 0.22±0.01 ml, 3.5±0.17 x10 9 sp/ml, 77.0±1.44% and 86.2±0.95 % respectively. In this study, glucose (G) including 5% Dimethyl sulphoxide (DMSO) cryoprotective, tris-glucose (TG), lactated Ringer's (LR), and lactated Ringer's glucose (LRG) extenders were used. The Turkey semen was combined and divided into four equal parts, and subsequently diluted at a ratio of 1:3 and equilibrated at +4°C for 90 minutes. Following equilibration, the samples were frozen in liquid nitrogen vapor to -80°C for five minutes, and stored at -196°C in liquid nitrogen. After freezing and thawing, the highest motility value was obtained from the G extender (43.3% ±1.62%) followed by LRG (24.6±1.53%), LR (12.6±0.92%) and TG (12.2±0.66%).The vitality values were recorded as 55.8±1.89%, 23.8±1.58%, 21.5±1.10% and 36.5±1.59% respectively. The motility and vitality values were significantly (p<0.01) more for the glucose extender than those for other extenders. Therefore, it was concluded that glucose extender is better option for the long-term storage of Turkey semen.

“…Artificial insemination (AI) is used very widely in turkey production but not in the production of layer pullets or broiler chicks. 102 Hens are inseminated weekly with diluted semen (for spermatozoa concentrations in turkey ejaculate see Table 20.2). While the technique is labor intensive, it takes advantage of the presence of spermatozoa storage glands in the oviduct.…”

“…While the technique is labor intensive, it takes advantage of the presence of spermatozoa storage glands in the oviduct. 102 These release spermatozoa after oviposition such that newly ovulated ovum can be fertilized prior to the addition of egg white, membranes and the she1l. 102 The AI techniques that were developed for poultry have been applied to the conservation of endangered wild birds when they fail to mate in captive conditions.…”

“…The contrast in the size of turkey toms and hens and consequent low fertility of the males after natural mating has resulted in the integration of Artificial Insemination (AI) in commercial production. AI has therefore been a critical component of reproduction in turkeys since the 1960s and is used almost exclusively for commercial flock production in some areas of the world (Bakst and Dymond, 2013). Reproductive performance is critical to efficient production in poultry (McDaniel et al, 1998).…”

The Nigerian local turkey has the potential to augment the supply of poultry protein in the country and across the region. However, the fecundity of the breed is low due to neglect and lack of improvement. This work is therefore aimed at shedding some light in some reproductive indices of the local turkey under optimum nutrition. A group of fifteen toms and nine hens were used in this study. The males were grouped into three groups of five and placed on varying levels of protein, 12% CP, 16% CP and 20% CP for groups 1, 2 and 3 respectively. Semen samples were collected and analysed twice weekly for thirteen weeks. Ejaculate volume, semen concentration, semen PH, gross and individual motilities, live and dead sperm and sperm morphology were investigated and recorded. Data were summarized as mean ± SEM (Standard Error of the Mean). The toms in groups 3 had significantly (P < 0.05) higher ejaculate volume 0.29 ± 0.03 mls and semen concentration7.766 ± 0.612 x10 9 than groups 1 and 2. The fertilizing ability, which was assessed through in vivo and in vitro sperm penetration assays revealed significantly higher number of sperm penetration holes (P < 0.05) in Groups 2 and 3, 160.97 ± 8. 084 and 172.83 ± 7.647 (in vivo); 187.96 ± 8.121 and 189.16 ± 6.446 (in vitro) respectively. The local turkey toms could parallel their exotic counterpart under optimum environment, without the need for genetic hybridization and that 20% CP had more positive influence on the semen quality and fertilizing ability of indigenous Nigerian turkey toms followed by 16% CP with 12% CP exerting the least positive influence.
