Isaac Michael, director of the Society for the Development of Community and a pig breeder, told Egypt Today on Saturday that the pig keepers are currently preparing to
rebreed pigs in order to reduce garbage.
To maintain a calving interval of 365 day, a cow must
rebreed within 80 to 85 days after calving.

rebreed while multiple parity Sahiwals had average days open of153 days.
"We're at a point where perhaps we could
rebreed the rose scent back into the flowers with all the petals," he says.
A brood cow whose calf is creep fed will
rebreed more quickly and require less feed to rebuild her body reserves if she lost weight during the time she was with the calf.
Loss of condition can inhibit her ability to
rebreed for the next season.
However, if an infection occurred when the uterus was replaced, the cow may be slow to
rebreed or may not breed back at all.
Determining if a ewe is open or pregnant helps you
rebreed open ewes quickly or cull open ewes at the best time.
Contrarily, cows calving in autumn face cooler months of winter after calving so
rebreed earlier due to comfortable season.
The first litter is frequently aborted, or reabsorbed, and the female will
rebreed with the new male.
None failed to
rebreed. We did find that fall-born ewe lambs usually would not breed their first spring.
Cows experiencing dystocia produce less milk and
rebreed later than those that give birth more easily.
