Koonjaenak S. 2006. Semen and Sperm Characteristics of Swamp Buffalo (Bubalus bubalis) Bulls for Artificial Insemination in Thailand, in Relation to Season. Doctoral thesis. ISSN 1652-6880, ISBN 91-576-7263-6 In this thesis work we tested the hypothesis that tropical climatic conditions affect the quality of fresh and frozen-thawed (FT) spermatozoa from swamp buffalo bulls used for artificial i...

This review summarises the most significant findings related to the issue of the quantitative and qualitative indicators of stallion ejaculates, its processing when producing chilled insemination doses and the possibility of influencing the individual steps of the entire process. Artificial insemination, with cooled-storage semen, is increasingly used in horse breeding because it offers many ad...

The sperm quality index (SQI) is predictive of fresh semen quality. Our objective was to examine if semen storage affects the SQI obtained from undiluted semen, or semen diluted with either Beltsville Poultry Semen Extender (BPSE) or Minimum Essential Medium (MEM) and held for 8 h at 4, 21, or 41 C. Dead o sperm percentage was higher and SQI was lower from undiluted versus diluted semen. Dead s...

The pig production must be sustainable, efficient and competitive to minimize its impact on environment. There is argument keep fewer breedable animals produce more numbers of piglets. In India, rearing still done traditional manner with low productivity. Artificial insemination (AI) the best reproductive technology available in current scenario for enhancing efficiency a sustainable way. This ...

Heparin binding proteins (HBPs) are produced by accessory glands. These are secreted into the seminal fluid, bind to the spermatozoa at the time of ejaculation, favour capacitation, acrosome reaction, and alter the immune system response toward the sperm. The present study was conducted with an objective to assess the effect of purified seminal plasma-HBPs (SP-HBPs) on cross bred cattle bull sp...

The aim of the study was to standardize the pellet cryopreservation procedure for chicken semen. Mericanel della Brianza male chicken breeders (Italian breed) were used. Pooled semen samples were processed according to the following conditions: (1) dilution in prefreezing extender to 1 versus 1.5 bill cells/mL sperm working concentration (SWC); (2) 6% versus 9% dimethyl acetamide (DMA) concentr...

Purpose: To determine the clinical relevance of determining the semen pH during semen analysis as per WHO (World Health Organisation) standard criteria among the infertile couple attending a tertiary ART (Assisted Reproductive Technology) Centre in South India. Methods: Regular Semen analysis as per WHO standards (2010) Results: The Semen pH value showed no major correlation with other Semen pa...

Liquefaction of human semen involves proteolytic degradation of the seminal coagulum and release of motile spermatozoa. Several members of human kallikrein-related peptidases (KLKs) have been implicated in semen liquefaction, functioning through highly regulated proteolytic cascades. Among these, KLK3 (also known as prostate-specific antigen) is the main executor enzyme responsible for processi...
