A study was carried out on semen of nine healthy mature breeding bulls (3 each of Gir, Surti and Murrah breed) to evaluate the correlations of their fresh sperm quality attributes to those of frozen thawed semen assessed both by subjective method and objective technique using Biovis CASA. The ejaculates immediately after collection were evaluated for routine seminal attributes.

Four Swamp buffalo bulls aged 5 to 8 years were used to study the fresh semen as well as biochemical characteristics. A total of 60 ejaculates comprising 15 from each bull evaluated for fresh semen characteristics and a total of 40 ejaculates comprising 10 from each bull were used for evaluation and biochemical characterization.

The objective of the current experiment was to investigate the various semen characteristics of two indigenous breeds of chicken namely Nicobari and Ankleshwar, as such data were not yet reported. Freshly ejaculated semen samples were collected from twenty breeder roosters of each breed and subjected to physical and biochemical analysis. Immediately after collection, the semen volume of individual birds was recorded using tuberculin syringe and further analysed for seminal motility, concentration and percentage of live, dead and abnormal spermatozoa using standard procedures.

The laboratory examination of semen quality parameters is an indirect way of assessing male fertility. The objective of this research was to study the semen quality parameters of Large White Yorkshire (LWY) boar ejaculates, which had the minimum sperm progressive motility necessary for being selected for further processing. The pigs were maintained at the Centre for pig production and research, Mannuthy, Kerala. A total of 24 ejaculates were collected from seven boars using gloved hand technique.

The mean ± S.E. values of seminal attributes evaluated for assessing the quality of freshly ejaculated neat semen from four Hariana bulls has been estimated. In the present study mean ejaculate semen volume ranges between 3.35 ± 0.14 to 5.38 ± 0.20 ml. Semen mass motility (0-5 scale) ranges between 3.13 ± 0.08 to 3.69 ± 0.09. Sperm concentration varies significantly among the four Hariana bulls and ranges between 1633.50 ± 33.58 to 1806.25 ± 31.56 millions/ml. Present study indicated that the percent sperm progressive motility amongst four Hariana bulls range between 72.0 0 ± 1.21 to 78.

The study was conducted in eighteen NARI Suwarna ewes with the objectives to establish an effective liquid semen sperm concentration for laparoscopic AI and to study the conception rates with natural and laparoscopic AI method in ewes. The ewes in estrus were detected using vasectomized ram and external signs of estrus and were randomly allotted to three equal sized Groups of six each (n=6) namely, natural mating (Group I), laparoscopic AI with 20 million sperm dose (Group II) and laparoscopic AI with 40 million sperm dose (Group III).

The zinc-binding protein semenogelin I is the major structural component of the gelatinous coagulum that is formed in freshly ejaculated semen. Se-menogelin I is a rapidly evolving protein with a primary structure that con-sists of six repetitive units, each comprising approximately 60 amino acid residues.
