Quantity, motility and fertility of tench Tinca tinca (L.) sperm in relation to LHRH analogue and carp pituitary treatments

Original language description

The spermiation of tench males was stimulated with Supergestran containing mammalian LHRHa lecireline at the following doses: 5, 10, 20 and 40 mu g kg(-1) b. w.; then with carp pituitary suspension (CPS) at a dose of 2 mg kg(-1) b. w. and with a controlof saline physiological solution. The following days, meaning 24, 48 and 72 h after injection, sperm was collected to evaluate volume and the number of sperm per male per kg body weight ( B. W.) The percentage of motile sperm and velocity of spermatozoawere measured 48 h after hormonal injection, and 72 h after hormonal injection the sperm was evaluated for fertilization and hatching ability. All 42 males in experimental groups were diploid. Live weight did not differ significantly among experimental groups. The strongest stimulation of spermiation was achieved with LHRHa in dosage of 20 and 40 mu g kg(-1) b. w. and CPS compared to males of the control group and lower dosage of LHRHa. Analysis of variance showed no significant influenc

Czech description

U lína obecného (Caille a kol., 2006) byla zjišťována úroveň spermiace 24, 48 a 72 hodin po injikaci Supergestranem obsahující savčí LHRHa lecirelin v dávkách 5, 10, 20 a 40 #g.kg-1 b.w., kapří hypofýzou v dávce 2 mg kg-1 b.w. a jako kontrola byl injikován fyziologický roztok. Nejvyšší stimulace spermiace bylo dosaženo s dávkou LHRHa 20 a 40 #g kg-1 b.w. a kapří hypofýzou ve srovnání s kontrolní skupinou a ostatními dávkami LHRHa. Průkazně nejlepší kvalita spermatu prokázána testem líhnivosti na úrovni61-64 % byla zjištěna u LHRHa v dávkách 20 a 40 #g kg-1 b.w. Naopak nejhorších parametrů líhnivosti bylo dosahováno při použití spermatu bez hormonální stimulace.
