Oestrus Induction

Background: Anoestrus is still one of the most prevalent reproductive disorders in dairy cows despite technological advances in animal husbandry. Evaluation of blood biochemical profile is of diagnostic value to determine disease or health status of animal. The current study was aimed to evaluate the effect of different therapeutic regimen on blood biochemical profile, oestrus induction response and conception rate of anoestrus cows.Methods: Thirty two postpartum anoestrus cows randomly allocated to four groups as G0 (negative control), GI, GII, GIII, GIV and 8 normal cyclic as GV (positive control). Dewormer and mineral mixture administered to GI, GII, GIII, GIV while group GII, GIII and GIV additionally received janova, sepia and Ovsynch protocol respectively.Result: Different therapeutic protocols have variable effects on blood biochemical parameters. Overall oestrus induction response in G0, GI, GII, GIII, GIV and GV is 0.00, 50, 62.5, 75, 87.5 and 100.00 per cent respectively with corresponding conception rate of 0.00, 75, 80, 66.66, 57.13 and 75.00 per cent. On the basis of findings it can be concluded that aforesaid therapeutic regimens have definite bearings on fertility and can be used to manage postpartum anoestrus in cows.

Autumn And Winter

SummaryThe seasonal and post-partum oestrus occurrence and ovarian activity, assessed by the plasma progesterone concentrations, were studied in Finn-cross ewes following autumn and winter lambings.The last seasonal oestrous cycle was followed by a silent ovulation in C0% of the Finn × Awassi ewes. Silent ovulations during midanoestrus occurred in 50% of the ewes, and in 90% of the animals a silent ovulation preceded the normal resumption of the seasonal sexual activity.The first post-partum oestrus occurred within C0 days after October lambings in about 90% of the ewes. Silent ovulations before the first post-partum oestrus were evident in 70% of the recycling ewes.It is suggested that breeding ewes with ovarian activity after oestrus induction during anoestrous periods might increase the reproductive performance of the flock in a frequent lambing system.

The purposes of this investigation were to determine the effects of different drugs such as GnRH analogue, vitamin AD3E and combination of vitamins and minerals on induction of cyclicity followed by conception in crossbred anoestrus heifers. The effects of body condition score (BCS) and age at anoestrus heifers during treatment on induction of cyclicity and conception were also determined. Sixty crossbred anoestrus heifers having > 2.5 BCS at >24 months age at Potiya Upazilla of Chittagong district were used. The cyclicity of the cows was confirmed by using real time ultrasonography on the basis of presence or absence of corpus luteum. The anoestrus heifers were allotted for 1 to 4 different treatment groups with GnRH analogue, vitamin AD3E and vitamin mineral solution including one no-treatment control group. AI was done in observed oestrus heifers and the conception was determined transrectally by using B-mode real time ultrasonography between 28-35 days post-Al. Heifers showed oestrus at higher (46.67%) proportion in treatment groups than that in no-treatment counterpart (6.67%) (P<0.05). The conception rate was 35.56% in treatment received heifers. The GnRH treated heifers showed the highest (60.00%) proportion of cyclicity and conception rate (46.67%) whereas vitamin mineral solution treated heifers showed the lowest cyclicity (33.33%) and conception rate (26.67%) (P<0.05). Heifers with BCS 3.5 had the highest (57.14%) rate of oestrus induction and (57.14%) rate of conception (P<0.05) whereas heifers with BCS 2.5 had the lowest (41.67%) rate of oestrus induction and (20.83%) rate of conception (P>0.05).  Heifer showed highest rate (50.00%) of cyclicity and (38.89%) rate of conception when their age ranges from 36 to 42 months where as heifer showed lowest (37.50%) rate cyclicity and (31.58%) rate conception when their age ranges from 24 to 29 months (P>0.05). In conclusion, treatment of crossbred anoestrus heifers with drugs has positive effect on induction of cyclicity followed by conception. GnRH may be the drug of choice among the drugs tested in this study. The BCS of heifers during treatment influences the treatment outcome with respect to induction of cyclicity followed by conception.
