The aim of this study was (1) to analy�e fresh intact or differently influenced rabbit sperm samples, using Annexin V–binding method for the detection of membrane phosphatidylserine translocation, and (2) to estimate obtained results in relation to the conceptional rate of rabbit females fertili�ed with semen from different groups. Following sample groups were designed: 1. freshly collected sem...

This study aimed to assess the effect of genetic and seasonal interaction on semen quality in Artificial Insemination Center. A total 36,754 ejaculation records were evaluated. The dependent variable was which consisted volume, pH, concentration, abnormalities, motility fresh semen. independent variables age, season, number ejaculation. mixed procedure with Tukey–Kramer multiple comparison test...

The functional integrity of spermatozoa in various domestic animals like horse, cattle and swine is evaluated by hypo osmotic swelling test. The hypo osmotic swelling test has not been tested in the fresh semen of Nili-Ravi buffalo bull. The aim of the present study was evaluation of membrane integrity by establishing the best hypo osmotic swelling solution. Ten solutions with different osmolar...

Although dog was the first species to be used for Artificial Insemination (AI) and become pregnant by Spallanzani in 1776, very little work has been done on preservation of dog semen to exploit the full genetic potential of pedigree males. Frozen semen is now inseminated routinely in cattle, sheep and goats and much research has been carried out with regard to the optimum conditions for its use...

The commercial applicability of bovine artificial insemination (AI) depends on the effectiveness of diluents for maintaining sperm fertility. Challenges faced by the AI industry due to recent advances in assisted reproduction, and the limitations inherent in using fresh and frozen-thawed sperm for AI, could be overcome with the development of better semen diluents. Research into the different m...

Abstract Status of bacterial diversity within the male seminal microbiome has previously been linked to fertility status in mammals. However, minimal research focused on reproductive boar semen. The objective this study was analyze communities fresh extended semen samples 1) between studs, 2) over 5 consecutive days, and 3) pooled single-sire doses. Eight (n = 4 per stud) eight doses (80 mL) we...

This study was conducted to assess the physical and morphological characteristics of fresh, pre-freeze and post-thaw black Bengal buck (Capra hircus) semen processed in Tris-egg yolk-citrate-fructose-glycerol (TEYCFG) extender containing 4 different concentrations (2.5, 5, 7.5 and 10%) of egg-yolk. Ejaculates were collected once a week for eight weeks from six mature bucks (48 ejaculates) using...

An experiment of factorial design was conducted to quantify variation in the components of reproductive wastage in Merino ewes following artificial insemination (AI) in either January, March or May. Semen from 6 individual rams was used in either fresh or deep frozen form, the latter providing a ram "control" to identify variation in wastage as of either paternal or maternal origin. Results sho...
