The Protective Effect of Solanum betaceum Extract on Spermatozoa Vitality Exposed to Lead Acetate in Mice

The purpose of this study was to analyze the effect of giving various dosages of Solanum betaceum extract on the vitality spermatozoa mice exposed to lead acetate. This research was true experimental using randomized post-test only control group design. The total sample was 40 mice which were divided into 5 groups. Lead acetate used a dose of 75 mg/kg BW and various extracts of Solanum betaceum namely 100 mg/kg BW, 200 mg/kg BW and 400 mg/kg BW. Acclimatization was carried out for 7 days and continued with maintenance and treatment for 35 days. Statistical tests showed that there was a significant difference with (p=0.026). In conclusion, Solanum betaceum extract can be used as a protective to increase the vitality of spermatozoa exposed to lead acetate

INFLUENCE OF ACCLIMATIZATION AND AGE OF IMPORTED BOARS ON THE QUALITY OF THEIR SPERM

In the paper the process of acclimatization and adaptation of boars on climate and microclimate conditions are described. The process of growth and sexual maturity during the breeding and accustoming of boars in taking sperms in the centers of artificial insemination or breeding stations are analyzed. It is concluded that appropriate microclimate conditions may solve sterility provoked by climate conditions and even increase fertility of pigs. For purchased and imported young boars it is very important that animals are raised in a proper way and trained for mounting and semen collecting. Ejaculate in the native sperm of imported boars is better quality comparing to the ejaculate of home breeds, but they are sensitive to unspecific infections that can reduce spermatozoa vitality, damage acrosome, disturb spermatozoa maturation and thus influence fertilizing of diluted semen. Housing and nutrition of high-born breed boars has important role in maximal exploitation of producing ability especially on longevity and lifetime production of the imported boars.
