19.用公猪来进行妊娠鉴定
USING THE BOAR FOR PREGNANCY CONTROL
19.1
19.1在妊娠舍,公猪的任务是进行发情鉴定
In The Gestation Unit The Boars Job Is To Make Heat Control
发情鉴定可以通过下列几点来完成:
Heat control can be achieved by:
让公猪在妊娠舍内的观察通道上走动 。处于发情期的母猪会靠近公猪 。
The boar walks around on the inspection path in the gestation unit. The sows that are in heat, will seek out for the boar.
将公猪放入母猪群时,要注意观察 。
The boar is in the group under observation.
公猪舍内装一台监视器,这可检测母猪是否过来接触公猪和接触的频率 。
The boar is housed in an enclosure with a boar detector which detects if the sow visits the boar andhow often.
公猪必须要每个星期换一次猪舍,这样可以保持其新鲜感 。
Boars must change pen every week to maintain their novelty value.
公猪需正确饲喂 。
The boar must be fed properly.
对于一头好的公猪,有以下要求:
For a good boar there are following requirements:
公猪必须活跃,性欲强 。
He must be active and virile.
公猪必须善于交际,友善 。
He must be sociable.
公猪必须有良好的体质 。
He must have a good constitution.
公猪不能太大,不然会吓到小的母猪 。
He must not be too big, so he scares the small sows.
公猪必须正确的接种疫苗 。
He must be vaccinated proberly.
记住,无论用什么方法,公猪只能发现那些发情明显的母猪 。
Remember, whatever methods, the boar can only fifind the sows that show oestrus.
公猪的效果会不明显,如果
The boar has little effffect if.
公猪总是和母猪在一起 。

补充说明: 用公猪来进行妊娠鉴定
Additional Comments: Using The Boar For Pregnancy Control
当公猪在妊娠舍内走动时,要仔细观察母猪的行为 。对公猪感兴趣和显示出发情迹象的母猪,要做标记并转移到配种舍 。
When the boar is taken around the gestation unit, the sows’ behavior should be observed carefully. Sows showing interest in the boar and shows signs of oestru, is marked and moved to the mating unit.
不建议将公猪和妊娠母猪饲养在同一圈舍内 。公猪不可能会和所有的返情母猪完成交配,也不能让所有的返情母猪出现明显的发情症状 。鉴定因 此会变的困难 。
It is not recommended to house the boar in the pen with the pregnant sows. The boar will not necessarily mate all the returners and inspection will not detect all the returners. The control will therefore become diffiffifficult.
如果公猪安置在有监视器的圈舍内,那对圈舍有特定的要求 。公猪要能够看到其它母猪 。要确保公猪不着凉,因此,猪舍必须有垫料,甚至安装保温盖 。母猪去接触公猪将会被电子仪器自动记录下来,但不能保证所有的发情母猪都会和该公猪接触 。
