Population Quality

Beyond the treatment of infertility, donor sperm is also made available to couples if the male partner is considered to suffer from a genetic disease and is deemed “not suitable for reproduction” because of a risk that the disease will be transmitted to offspring, thereby negatively affecting the quality of China’s newborn population. There are far fewer cases of donor sperm being used in this way than to address infertility. Chapter 2 shows how artificial insemination by donor both purports to contribute to the improvement of national population quality while, at the same time, introducing a potential threat to this quality in the form of possible unwitting consanguineous marriage of donor siblings. Sperm banking in China is inextricably bound to national family planning objectives to improve the quality of newborns.

From crude and uneasy beginnings, sperm banking has become a routine part of China’s pervasive and restrictive reproductive complex within the space of thirty years. It covers the introduction of assisted reproductive technologies (ARTs) to China to address infertility, the expansion of the use of donor sperm in cases in which the male partner suffers from a genetic disease, and other issues, such as the availability and screening of potential sperm donors.

The purpose of this research was evaluate the quality of spermatozoa concentration in the caput, corpus and cauda of the swamp buffalo epididymis (Bubalus bubalis carabanensis).  Method of this research was to exploration to 13 epididymides of eight swamp buffaloes were obtained from Banjar and Banjarmasin slaughterhouses,evaluated the quality of spermatozoa in caput, corpus and cauda of epididymis.  Quality of collected-spermatozoa including spermatozoa motility, percentage of live spermatozoa, spermatozoa concentration and percentage of abnormality.  Result of this study showed that mean of each of caput spermatozoa motility, percentage of live spermatozoa, spermatozoa concentration and percentage of abnormality; 0%, 45.43% (31.87–72%), 189,62 x106 (40–480 x106) and 56.16 %(44.34–66.53%), corpus ;2.77% (1–9%), 58.73% (45.14 –76%), 152.31 x106 (45 – 345x106), and 47.61 %(23.92 – 60.15%), cauda;53.46% (20 – 70%), 74.32 % (56.68 – 83%), 1,459.62 x106 (825 – 2,340x106), and 34.60%(15.89 –50.04%). In conclusion, spermatozoaofcaudaepididymis could be used in artificial insemination program.Keywords: Spermatozoa, epididymis, swamp buffalo.

The Relationship

One of the problems that exist in the community is the lack of identification of the reproductive performance of prospective brooders of Bali cattle that are artificially inseminated. The researcher conducted a research to determine the reproductive performance of Bali Cattle inseminated with Brahman Cattle Semen in SECP (Special Effort for Cows to be Pregnant Program) Program in Kolaka Regency. The parameters observed in this study were; artificial insemination's first age (Years), How many times the artificial insemination (AI) was pregnant (S/C), Length of pregnancy (months), Calving Interval (CI) (months), Birth weight (Kilograms), Correlation of AI's first age with birth weight. Sources of date used in this study are primary and secondary data. Data collection techniques carried out in this study were observation and interviews. The date obtained was analyzed descriptively, analysis of variance, average, and to calculate the relationship between variables was analyzed by correlation. Reproductive performance of Bali Cattle inseminated with Brahman Cattle Semen in SECP Program in Kolaka district include; first age AI 23.63±1.99 months, Service per Conception (S/C) 1.56±0.55, gestational age 9.03±0.38 months, Calving Interval (CI) 12.24±0 .52 months, birth weight 27.85 ± 2.96 and the correlation between AI prime age and birth spacing was 0.77.
