“…The higher number of dead and abnormal spermatozoa in the semen of the guinea cocks obtained in this study may be attributed to the collection procedure which appeared difficult in the Numidia meleagris. Furthermore, the live spermatozoa (Plate IV) were still within the range (> 70 -75 %) acceptable for avian AI (Zahradden et al, 2005;Yahaya et al, 2013) and abnormalities were mostly secondary type (Plate V) similar to previous reports by Mohan et al (2016). Microbes inhabiting avian cloaca are correlated strongly with semen contamination in poultry during collection procedures (Ngu et al, 2014).…”

This study aimed to isolate bacteria flora in fresh semen of helmeted guinea cock (Numidia meleagris) and Nigeria local turkeys (Meleagris gallopavo) and determine the sensitivity of the semen microbes to antibiotics with further assessment of sperm quality characteristics in the freshly collected semen. Five matured guinea cocks weighing approximately 3 – 4kg and five matured turkey toms of 10 – 14kg body weights were selected for the study as sperm donors. Semen collection was done twice a week for five weeks using a modified abdominal massage method and ejaculates were pooled independently based on the animal group. The pooled ejaculates in each species were further divided into aliquot A for spermiogram analysis and aliquot B for microbes and antimicrobial sensitivity analysis using standard methods. Results showed that freshly collected semen from both donor birds were contaminated; although, presented good qualities when evaluated for sperm characteristics such as progressive motility (%), livability (%), morphologic abnormalities (%) and concentration (cell×109/ml). Isolated contaminants included Escherichia coli, Shigella spp, Staphylococcus aureus and Bacillus spp in fresh semen of the helmeted guinea cocks, similar in turkeys except for Shigella spp. The organisms were all sensitive to streptomycin, gentamycin and pefloxacin except the Staph aureus which showed resistance to pefloxacin and Bacillus spp which was resistant to gentamycin. It was then concluded, that whereas freshly collected semen of guinea cock and turkey toms were contaminated during collection, they still possessed good quality traits when evaluated for semen characteristics and antibiotics like streptomycin, pefloxacin or gentamycin are recommended for use during in-vitro processing and extension of semen from both poultry species.

“…The ejaculate characteristics of turkey toms showed that the toms were reproductively active and as a result voided semen that were of good quality. This was because, results of the physical evaluation of ejaculates of the toms -semen volume, progressive sperm motility, spermatozoa concentration, total number of sperm cells in ejaculate and percentage of normal spermatozoa in ejaculates, were within ranges reported for normal turkey toms [18,19]. A marked improvement in the number of eggs laid and the percentage of fertile egg at candling was observed in hens treated with OSE and PSS indicating possible improvement in the reproductive rate of the birds.…”

An experiment was conducted to determine the fertility and hatchability of eggs laid by Turkey hens fed extracts of okra seed, pumpkin seed and guava root powder for 8 weeks. Twenty four, 32 weeks old turkeys (4 toms and 20 hens) were randomly selected and allotted into four treatment groups; T1 (No extract or feed supplementation); T2 (50 ml okra seeds extracts/ litre of water); T3 (50 ml guava root extract/ litre of water) and T4 (50 g pumpkin seed powder/kg of feed). Turkey hens were subjected to artificial insemination and eggs laid in the period were collected and determined for fertility and hatchability. Total and weekly egg production of hens was higher (P < 0.05) in T2 and T4 groups of birds. The number of fertile eggs, early, middle and late dead embryo was better (P < 0.05) for the same groups of birds compared to other treatments. Egg hatchability percentage of hens in T2 and T4 groups were markedly improved and higher (P < 0.05) than those in T1 and T3 groups. Fertility and hatchability of eggs in T1 and T3 were similar (P > 0.05). The findings concluded that feeding okra and pumpkin seed extracts to breeder turkey hens can improves the fertility and hatchability of the eggs.

Semen Characteristics and artificial insemination in rockhopper penguins (Eudyptes chrysocome chrysocome)

This work was performed as part of a multi-year study to determine the cause of the low fertility in captive rockhopper penguins (Eudyptes chrysocome chrysocome) and attempt to increase the fertility through artificial insemination (AI). Semen collection and characterization was performed on 14 male rockhopper penguins. The samples were evaluated for volume, sperm concentration, and sperm quality (motility, forward motility, viability, and morphology). There was a large variation between individuals and between collections for each individual. Mean volume of ejaculate was 0.24 ml. Mean concentration was 47.09 × 10(6) sperm/ml. Mean number of sperm per collection was 6.57 × 10(6). The mean motility was 49.4%. Mean forward motility was 1.7. Mean percentage of living sperm was 88.9%. Mean percentage of sperm with normal morphology was 69.4%. AI was performed on a total of 10 females using pooled semen samples. The birds were also allowed to naturally mate. Ten eggs were laid and three fertile eggs were produced, one of them hatched but died within 24 hr. Paternity testing was performed using 12 microsatellite loci, but unfortunately due to insufficient variability, the paternity of the chick and two embryos could not be determined.
