The experimentatl resuls show that treament doses of 3.57J/cm 2and 7.14J/cm 2 are optimum doses,being able to imptove semen quality,increase metablic function state of sperms and vitality;
The partial correlation coefficent of semen quality of semmital bulls and thermal elements,two thermal indexes(THI,WCI)from Sep.1993 to Aug. 1994 was statised on the computer.
This article analyses the factors influencing semen quality of black and white breeding oxen from three aspects of source, season and age, uses minimum range method to make multiple contrast.
Zinc and testosterone concentrations in serum and seminal plasma of 9 bulls were determined for 5 times, results showed that the relationships between the zinc and testosterone and the semen quality were highly positive correlations.
Research on the Correlation between Scrotal Circumference and Main Traits of Sperm Quality and Screening Genes of Scrotal Circumference in Cattle by DDRT-PCR
After 45 days, sperms were collected from injected mouse, the sperm quality was examined and PCR technique was employed to examine the integration of neo R into the genome of sperms.
2. The rams with deficiency zinc were fed 53.83mg/kg-65.26mg/kg can increase some indexes of seminal quality with fed days, after 60 days it possessed ideal condition.
10 mature male tail sheep were selected and divided into 5 group at random,fed with the different concentrations of zinc,to study the relationship between days of feed and seminal quality.
SEASONAL CHANGES IN PLASMA TESTOSTERONE,ESTRADIOL-17β, PROGESTERONE AND CORTISOL CONCENTRATIONS AND THE RELATIONSHIP BETWEEN THESE HORMONES AND LIBIDO AND SEMINAL QUALITY IN GUANZHONG MALE DAIRY GOATS
The protective role of vitamin E and GSH with respect to boar semen against fatty acid peroxidation and a positive influence of vitamin E supplementation on semen quality have been evidenced.
In men, effects on sperm quality and motility, delayed sexual development, and small testicular size have been described in association with AED treatment.
We concluded that changes in trace elements may be related to sperm quality and that lipid peroxidation, although it is not promoted in the seminal plasma by copper or iron or ameliorated by zinc, may be involved in the loss of sperm motility.
This leads to spermatogenic arrest, impaired motility, and sperm quality and results in morphologic alterations of the testes similar to those observed in prepubertal testes.
