Semen dilution effects on reproductive performance in turkeys.
Abstract Interest in economizing with respect to the cost of poult production has prompted the use of semen diluents, with a view to reducing the number of toms required to inseminate a given number of turkey hens. In connection with this practice, there exists a fairly voluminous literature dealing with constituents of diluents for turkey semen; an access to this literature may be gained by beginning with Bajpai and Brown (1967). Brown (1971) referred to a study by Graham and coworkers in which semen diluted 1:2 with an insemination dose of .025 ml. gave as high fertility as undiluted semen. However, Brown (1970) found depressing effects on fertility due to dilution of semen and speculated that his results probably disagreed with those of Graham and coworkers because of such factors as season of the year, age of the breeders and frequency of insemination. The study reported here deals with the main…
Effect of Carbon Dioxide Diluents on the Fertilizing Capacity of Turkey Spermatozoa
Abstract LACK of information on a diluent containing carbon dioxide as a reversible induced Bajpai and Brown (1963a) to study the possibilities of using carbon dioxide diluents in storing turkey semen. Bajpai and Brown (1963a) reported that although the Illini Variable Temperature diluent (I.V.T.) and G-1 diluent (sodium glutamate substituted for sodium citrate in I.V.T.) containing carbon dioxide preserved turkey semen adequately in the laboratory both I.V.T. and G-1 diluent markedly inhibited the fertilizing capacity of turkey spermatozoa. However, in a subsequent study Bajpai and Brown (1963b) reported fairly good fertility (63 percent) with a glutamate diluent containing carbon dioxide and no egg yolk and poor fertility (35 percent) with a glutamate diluent containing 10 percent egg yolk by volume and no carbon dioxide. In the same year Harris et al. (1963) in a research note reported that the average fertility for turkey semen stored for six hours in a carbon …
Antimicrobial activity in pulp extract of Neem(Azadirachta indica Linn.)
Antimicrobialactivityin leaf extract of neem ( Azadirachta indica ) against human pathogenic bacteria. E.coli, Staphylococcus aureus, Pseudomonas aeruginosa , Salmonella typhimurium, Bacillus pumilus. Antimicrobia l activities of alcoholic extracts of neem leaves were used. Varying concent ration of each extracts 200mg/ml, 150 mg/ ml,100mg/ml, 50mg/ml, 25mg/ml prepared by using disc diffusion method. When compared with gentamycin 200mg and gentamycin 10mg, the methanol and ethanol extract shows maximum inhibition on Bacillus pumillus, Pseudomonas aeruginosa and Staphylococcus aureusin an asending order.
