Abstract:

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). Thick creamy white semen samples with good mass activity, initial motility more than 70% and average sperm concentration around 5000 million was collected using an artificial vagina (AV). Freshly collected semen sample was diluted with Sodium citrate- egg yolk extender at 37◦C to achieve the concentration of 20 million spermatozoa/ dose for Group II and 40 million spermatozoa/ dose for Group III (Volume-0.25ml) for Laparoscopic AI. The laparoscopic AI was performed between 12-24 hrs after onset of estrus. Conception rates recorded for Group I, II and III were 33.33%, 16.66% and 66.66% respectively. Over all conception rate with laparoscopic AI was 41.66%. Laparoscopic AI with use of 40 million sperm/dose yields significantly better conception rates than 20 million sperm/ dose. It is concluded that laparoscopic AI can be effectively employed with the low sperm dose of 40 million when stress factors are taken care of.
