From;  Author:Stand originally

The production that raise a pig is turned in the factory in the process, to improve the utilization rate of piggery and efficiency of the production that raise a pig, all adopt commonly enter completely go out completely, the means of balanced production, with Zhou Wei section law has production, raise a certain quantity of sow namely, form a product line, every product line by hybridization, gravid, childbirth, child care, grow, Yo is become wait for link composition. In order to raise 600 foundations sow, year 10 thousand product line of pig of 10 thousand commodity are a column exemple, produce per year 2.1 broods of computation on average by every sow, annual but kitten 1260 broods, average and weekly kitten 24 broods, namely weekly and due 24 sows deserve to go up kind, 24 sows kitten, pig of 24 broods of youngs ablactations to be abandoned into child care, pig of 24 broods of fatten gives column.

Every product line is abandoned by hybridization, gravid abandon, childbirth is abandoned, child care is abandoned, grow abandon and Yo is become abandon composition, and the size of every piggery depends on the amount of the sty in of all kinds piggery and range way. The method comes true by the following:

The amount of of all kinds sty inside 1 product line

The factory is changed raising a pig is with law of Zhou Wei section, it is an unit in order to raise unit, execute produce a system into what go out completely completely. After going out completely, should undertake be cleaninged thoroughly alexipharmic, the lopsided sex in considering actual production process andManagementThose who go up is convenient, each piggery still should raise a certain quantity of motor-driven hurdle, it is the sty amount that adds 1 week commonly, so that rinse,use when disinfection and motor-driven.

1.1 boar column

The production that raise a pig is turned in the factory in, the scale of fair sow is 1 ∶ 20. It is with 10 thousand product line exemple, boar of sheep wanting raise 30, should abandon in hybridization so inside set 30 boar column; Year of newer rate of boar for 50% , answer every year to wash out 15 boar newlier, because this returns need,install 4 ~ column of 5 mothball boar.


1.2 sows column

Because the sow is abandoned in the hybridization of product line, gravid abandon, childbirth is abandoned between circularly, so the amount of column of the sow inside every piggery depends on the sow abandons the time holding pen inside in each.

1.2.1 sows abandon the time holding pen inside in hybridization: Hybridization turns to abandon after the sow ablactations, general classics 4 ~ hybridization of 5 days of oestrus, control on average for 7 days, an oestrus cycle is like the repass after hybridization to be sent no longer situation turns namely gravid abandon. So the sow abandons the time inside to should be equal to in hybridization from ablactation to be counted to the day of hybridization, plus an oestrus periodic day is counted. Namely =28 day or 4 weeks.
