Cloprostenol-induced versus Spontaneous Oestrus Fertility in Dairy Cows
A short calving to conception interval is of main importance to achieve high economic efficiency in dairy cow industry. In order to reduce this interval, several hormonal treatments have been put on the market, in which cloprostenol, a synthetic analogue of prostaglandin F2 (PGF2). Is it better than the `normal` spontaneous oestrus? An interesting study on more than 500 dairy cows from Italy.

The aim of this study was to compare fertility of cloprostenol-induced oestrus to that of spontaneous oestrus in dairy cows.

In a group of 525 cows, 280 (treated group) were administered 0.5 mg cloprostenol i.m. after transrectal corpus luteum (CL) detection, and inseminated at detected oestrus during the following week.

The other 245 cows (control group) were inseminated during spontaneous oestrus. Whey progesterone concentrations were checked at treatment and at insemination in order to remove from the study cows whose P4 levels indicate a non-functional CL, or a lack of luteolysis respectively.

Moreover, cows that were not inseminated due to genital problems were also excluded from this study.

Conception (59% vs 54.5%) and calving rates (93.7% vs 93%) were not significantly different between the two groups.

Monensin and essential oils in transition dairy cows
This work examined preventive effects of a dietary and a medical intervention measure on postpartum (p.p.) ketogenesis in dairy cows overconditioned in late pregnancy. Sixty German Holstein cows were allocated 6 weeks antepartum (a.p.) to three high body condition score (BCS) groups (BCS 3.95 ± 0.08) and one low BCS group (LC, BCS 2.77 ± 0.14). Which effect does the oral addition of monensin and essential oils have on performance parameters and energy status?
