M. Krajnicakova et al., THE EFFECT OF DEPOTOCIN INJ SPOFA ON CONCENTRATIONS OF CHOLESTEROL, TOTAL LIPIDS, PROGESTERONE AND ON THE CONCEPTION RATE IN POSTPARTURIENTEWES, ACT VET B, 64(3-4), 1995, pp. 263-268
The effect of Depotocin inj. Spofa on concentrations of cholesterol, t
otal lipids and progesterone with subsequent synchronization effect on
the conception of ewes was studied. A total of 19 ewes were included
in the experiment; 10 animals served as a control, and 9 sheep were tr
eated with Depotocin inj. Spofa 2 - 0 - methylthyrosin (deamino -1 - c
arba) oxytocinum at a dose of 2x0.07 mg, 24 and 72 h after lambing, re
spectively. Blood samples were obtained from v.jugularis at 36 h post
partum, and on days 4, 7, 14, 17, 21, 25, 34, 42 and 51 after lambing;
Agelin vaginal tampons were inserted to sheep of both groups after da
y 51 (20 mg of chlorsuperlutine). Ten days later, the tampons were rem
oved and the animals were injected with 500 I. U. of PMSG. The expecte
d date of parturition was calculated from the date of mating. Choleste
rol and total lipids were determined using BIG-LA tests (LACHEMA, Brno
) and the concentrations of progesterone were determined by the radioi
munological method, using kits from URJVT, Kosice. Cholesterol concent
rations showed no significant differences between the control and expe
rimental groups (P > 0.05). The concentrations of total lipids oscilla
ted in the experimental group from day 25 post partum at non-significa
ntly higher values in comparison with the control group by the end of
the period studied (1.78+/-0.48 to 2.45+/-0.35 g . 1(-1)). In the expe
rimental group, the levels of progesterone increased slowly on days 34
and 51 (0.5+/-0.8 to 0.8+/-1.3 nmol.l(-1)). In other sampling days, i
ts values were under the level of sensitivity of the trial. In conclus
ion, lambing after the oestrus induction on day 51 post partum showed
that a 100% lambing with birth of 16 lambs was achieved in the experim
ental group whereas in the control group only 5 out of 10 mated animal
s lambed.
