“…In other reports by Galor (1983) and Ayorinde et al (1989) however stated that the fertility of guinea eggs under artificial insemination was found much higher than that of natural mating. In present study, although the breeder stock of guinea fowl subjected to natural copulation however the egg fertility resulted 80%, which was almost comparable to the egg fertility observed by Surai and Wishart (1996) in artificially inseminated birds. It is well documented that the guinea fowls are monogammy in nature, and as a result egg fertility usually should be higher if birds kept 1:1 male-female ratio compared to provide more number of females against a male.…”

Present study was carried out to evaluate the hatching and growth performances of guinea fowls (Numida meleagris) kept under intensive rearing system at the Bangladesh Agricultural University Poultry Farm, Mymensingh. To develop a base population of guinea fowls at BAU Poultry Farm, a good number of hatching eggs were collected from different regions of the country. In first phase, the physical features of hatching eggs, their incubation period, care and handling of eggs during incubation, their fertility and hatchability were investigated. Eggs were hatched in a home incubator incubator at BAU Poultry Farm. In second phase, brooding management of the keets, growth performances, prevention and control of diseases and mortality of the birds were observed. All the activities were performed at the Laboratory of Poultry Science and the Poultry Farm of Bangladesh Agricultural University. Brooding of keets was performed under full intensive system in a littered floor. Broiler starter feed was supplied during the brooding period. Results showed that the shape of egg was top like and both white and spotted cream color shell was found. The average egg weight was 38g per egg and shell thickness was 0.52 mm. The incubation period was 28 days. Fertility and hatchability on set eggs were 80 and 68%, respectively. Dead in shell and dead in germ were 15 and 4%, respectively. The average day-old keet weight was 25.8 g. Average feed intake per bird per day during 0-4, 5-8 and 9-11 weeks of age were 10.22, 30.91 and 52.6 g with the feed conversion ratios were 3.25, 3.05 and 2.88, respectively. The keets mortality up to 11 weeks was 10%. Economic feasibility should be taken into consideration with the observation of egg production and other associated parameters keeping guinea under complete free-range rearing system.Progressive Agriculture 27 (1): 70-77, 2016

“…polyvinyl-pyrolidone), rapid or slow freezing/thawing rates and pellet or straw packaging. A 'historical' picture of the progress and still unanswered questions concerning avian sperm cryopreservation can be obtained from several reviews published in the last few years by Hammerstedt (1995), Surai and Wishart (1996), Donoghue and Wishart (2000), Massip et al (2004) and Blesbois (2007). Briefly, several workable methods are currently available for use in the chicken with different internal cryoprotectants (Figure 3), while results in other species remain inconsistent or insufficient.…”

This review focuses on some of the main features of sperm selection and storage in birds mainly on the basis of studies performed in poultry species, with emphasis on the initial selection of sperm at the female vagina level prior to migration towards the sperm storage tubules. Sperm originating from low-quality males or subjected to inappropriate in vitro storage conditions are rapidly discarded, resulting in impaired fertility in corresponding flocks. In the absence of accessible and appropriate technology for matching the 'storing' potential of sperm in the oviduct, conditions for prolonged sperm storage under a liquid (through the use of semen extenders) or a solid state (cryopreservation) have received only limited attention, despite their potential interest to facilitate male and female management in poultry flocks. Despite this, technology for shortterm liquid storage is currently used in turkeys, guinea fowl and muscovy ducks and also in progress in chickens. In addition, technology for cryopreservation of avian semen has become available for some species (chicken, goose) to facilitate the management of genetic resources, including the preservation of rare and economically important breeds.

“…Fresh semen samples were diluted in IGGK diluent (Suraï & Wishart 1996) to reach the final concentration of 3 £ 10 9 spermatozoa/ml. Because the use of DMA did not provide fertile samples after freezing-thawing following either the chicken or the turkey procedures used previously, or various adaptations of these methods (unpublished observations), samples of semen were then cooled to 4 8C before the addition of 6% dimethyl formamide (DMF).…”

The ability to survive cryopreservation varies in spermatozoa from different bird species. Among the biological factors potentially responsible for such differences, species variations in membrane fluidity have a role in the restoration of the physiological state after freezing. Membrane fluidity may be assessed by measuring fluorescence polarization anisotropy with a fluorescent dye. Anistropy values are proportional to membrane rigidity and consequently inversely proportional to membrane fluidity. In the present study, polarization anisotropy of spermatozoa originating from species differing in the freezability of their semen (chicken, turkey and guinea fowl) was measured in addition to lipid composition (cholesterol/phospholipid ratio), sperm viability (membrane permeability to eosine) and morphological integrity before and after cryopreservation. The percentages of viable and normal spermatozoa in fresh sperm were highest in the chicken (87%), lowest in guinea fowl (64%), and intermediate in turkeys (69%). Anisotropy values were highest in guinea fowl (0.205), lowest in chickens (0.155), and intermediate in turkeys (0.180). As a consequence, membrane fluidity was highest in chickens and lowest in guinea fowl. Cryopreservation significantly decreased sperm viability and morphological integrity and increased anisotropy in all species but did not change the inter species hierarchy. Initial cholesterol/phospholipid ratios were lower in chickens than in guinea fowl, and intermediate in turkeys (0.25, 0.26 and 0.29, respectively). Cryopreservation induced a severe decrease in cholesterol/phospholipid ratios in turkeys and guinea fowl. Sperm membrane fluidity in chickens, turkeys and guinea fowl behaves as an indicator of sperm freezability in these species. Inter species differences for this parameter may be partly explained by differences in initial cholesterol/phospholipids content of spermatozoa. On the other hand, the rigidifying process induced by cryopreservation is not related to lipid damage by the same mechanisms.
