In commercial production systems for swine, the early weaning of piglets has several key advantages including improving feed conversion efficiency of the piglet, shortening farrowing intervals to encourage rebreeding
, and minimizing the potential transfer of disease from sow to offspring.
She might continue to give milk for six to 10 more months without rebreeding
The limousines were added in the 1980s, originally for rebreeding

the same sire and dam litter after litter just because it's easy and profitable.
Effects of feeding zearalenone to sows on rebreeding
The other issue was weaning the lambs at around five weeks so the ewes could get a brief break before rebreeding
Keogh have found that calving difficulty, rebreeding
, and calf survival depend on many factors (see story on page 4).
Alpaca females are induced ovulators and can become pregnant any season of the year, so we sometimes will delay a dam's rebreeding
if her first cria for us was born in summer or winter, that can be less than optimum due to our climate.
The cost of lost calves and slower rebreeding
caused by dystocia diminishes the value of large birth weight.
Dairy farmers have three options when the fertility of dairy cows decline: i) remove cows from the milking herd and finishing for slaughter; ii) sell cull cows at salvage value for milking or to the slaughter house; iii) carry out extended lactations with rebreeding
to facilitate calving at 18 or 24 month intervals (Auldist et al.
