Days in milk (DIM), DIM × DIM, and ambient temperature were entered as quantitative variables and number of calves, parity, calving difficulty, day relative to breeding, day of somatotropin treatment, and 25 health event categories were entered as categorical variables.
Our study shows that within a single breeding day, the majority of the progeny can be produced with the contribution of just two females and 10 males, which amounts to an effective population size (Ne) of 6.7 while there were 43 participating breeders and a total number of initial individuals of 57 (Ne/N = 0.12).

Only a few females arrive at the pond for breeding each day, so piracy is a way for more males to be involved in reproduction.
Dr. Kraemer is devoted to bulldogs and sees the heartbreaking consequences of bad breeding every day in his veterinary clinic in Orange County, CA. As medical director for SoCal Bulldog Rescue (SCBR), Dr Kraemer houses, feeds, and provides medical treatment for up to 25 rescued Bulldogs at any given time.
Milk samples from bred buffaloes were collected at Day 0 (day of breeding), Days 10 12 and Days 22 24.
Female Long-Evans hooded rats were exposed to MeHg (0, 3, 6, or 9 ppm as drinking solution), Hg vapor (0, 300, or 1,000 μg/m for 2 hr/day), or the combination of both, from 30 days before breeding through gestational day 18.
"You remove the breeding site one day, and the next day, it's back," she says.
Therefore, it is reasonable to propose that if the buffalo was domesticated in the Indian subcontinent, the Western region represented by the present day breeding tract of the Mehsana, Surati and Pandharpuri breeds appears to be the most likely candidate.
Our data are consistent with the available archaeological information in supporting the proposition that the river buffalo was likely to be domesticated in the Western region of the Indian subcontinent, specifically the present day breeding tracts of the Mehsana, Surati and Pandharpuri breeds.
If the river buffalo was domesticated in the Indian subcontinent, as has been suggested by archaeological studies, the Western region represented by the present day breeding tract of the Mehsana, Surati and Pandharpuri breeds appears to be the most likely candidate region.
