A total of 81 ejaculates collected from 4 Tellicherry and 2 Boer bucks were utilized to evaluate the structural and functional integrity of spermatozoa as a measure for quality assurance of cryopreserved buck semen. The semen samples were diluted with tris-egg yolk-glycerol based extender and frozen in straws. Only samples having 40% or more of post thaw motility (PTM) were regarded as “acceptable†samples for artifi cial insemination. The “acceptable†samples were further evaluated by hypo osmotic swelling test (HOST), sperm morphology and acrosome integrity assessment. Individual genotypes have shown signifi cant variations (P < 0.01) for PTM. Significant variations (P < 0.01) were seen between bucks and between ejaculations of two Tellicherry bucks for hypo osmotic reacted spermatozoa. The differences in mean values for hypo osmotic reacted spermatozoa between I and II ejaculations of Tellicherry bucks were significant (P < 0.01). Signifi cant variations (P < 0.05) were also observed for hypo osmotic reacted spermatozoa between I ejaculations of Tellicherry and Boer bucks. The variations in means of intact acrosome percent between I and II ejaculations of Tellicherry bucks was signifi cant (P < 0.05). Besides post thaw motility, incorporation of structural and functional integrity tests like HOST and acrosome integrity in semen evaluation protocol add value to quality assurance of frozen buck semen.

The study was conducted in government recognized and unorganised slaughter houses of sheep and goats in Jammu from the month of July 2013 to June 2014. In the present study, 300 kidney samples of sheep (150) and goats (150) were collected from these abattoirs for determining the patho-morphological changes. Prominent gross lesions in kidney affection included haemorrhage, infarction, hydronephrosis, amyloidosis and nephritis. Histopathological examination revealed massive interstitial haemorrage, MNC’s infi ltration, atrophy of glomeruli with presence of pinkish amyloid material, hypercellularity of glomeruli and tubular necrosis.
