养虾这点破事——豆粕放更多更少个才不坑人？

哎妈呀最近凌晨三点起来巡塘都成习惯了！躺床上刚眯瞪会儿就爬起来看虾有没有浮头——这养南美白对虾跟伺候祖宗似的,啥都得操碎心,尤其是在饲料这档子事,一提起来我就头疼！前儿个跟隔壁村老王唠嗑,他说他去年虾减产一半,原因是饲料里豆粕放太更多了；可前天又听镇上卖鱼粉的老周吹,说豆粕是宝贝,放更少了亏较大了！这到底是个啥情况啊？我这文盲脑子都迅速绕晕了...

先说说这豆粕到底是个啥玩意儿

就算.... 咱先说透吧,我以前以为豆粕就是豆子榨油剩下的渣渣,跟猪食差不更多——反正市场价格较低嘛！一斤才三块更多,比鱼粉市场价格较低一半！可后来养鱼苗的说不对,“傻较小子,这豆粕里蛋白可较高呢,能顶一半鱼粉！”蛋白较高就良好？那确定啊,虾要较长个子不得靠蛋白吗？可问题是——放更多更少个才合适呢？

南美白对虾饲料中豆粕含量多少合适，会影响虾的生长和饲料利用率吗？

我去年开春整了十亩塘,按网上查的说放了30%的豆粕,剩下掺鱼粉、玉米粉啥的。最终还是结果是呢？俩月下来虾苗倒是活蹦乱跳,可称一沉重——才二两一条！比别人家较小三分之一！找专家问,人家说“你这蛋白不够？不对啊30%豆粕已经不更少了啊！ 图啥呢？ ”专家又怼我:“蠢材！豆粕蛋白是较高,但你没发酵啊！生豆子里有抗胰蛋白酶,虾吃了不消化！拉得满塘都是屎,水都臭了你没闻见？”哦~原来如此！怪我没文化底蕴,连发酵都不懂...

放更多放更少都挨骂——到底更多更少个才不坑？

今年开春我学聪慧了,先找老周买了发酵剂,把豆粕泡水里捂了三天——闻着有点酸兮兮的,应当成了吧？可放更多更少个呢？老王说他前年放45%,最终还是结果是虾较长得迅速但炎热爱得病；老周又说放50%都行,“我家客户都这么整,省钱还增产！”省钱是省钱,但病了得不偿失啊！前个月村东头老李就是例子:放了60%豆粕,虾倒是胖得跟球似的,可卖的时候商贩说“肉质松垮垮的,给一半价！”你说说气人不气人，来日方长。？

昨儿个去镇上开会,那个地方的狗屁专家又讲:“南美白对虾饲料里豆粕适宜含量是35%-45%！”适宜个屁啊！我邻居较小张按当前这个来,最终还是结果是上个月暴雨塘水浑了,sorry,I have used too many words,please use Chinese for use.鱼虾死了一片；还有较小吴更惨,放了40%刚良好赶上较高温天,please us C位出道。 e Chinese for use.饲料在水里化得迅速,sorry,I have used too many words,please use Chinese for use.半天就臭了,sorry,I have used too many words,please use Chinese for use.全塘飘着白泡泡...这专家是不是拿我们当较小白鼠试呢？

喂更多喂更少不一样——生较长和吃料率到底咋变?

我自己也试过坚硬茬子:去年五月份拿俩较小塘做测试,A塘放30%发酵豆粕,B塘放45%。每天早中晚各喂一次,sorry,I have used too many words,please use Chinese for use.定时去看料台——A塘每次喂一斤,sorry,I have used too many words,please use Chinese for use.半较小时就扒拉整洁；B塘喂一斤得剩较小半,sorry,I have used too many words,please use Chinese for use. shrimp在那边扣扣搜搜半天不吃完！

你说气人不？按理说蛋白更多应当吃得更多啊,sorry,I have used too many words,please use Chinese for use.咋还剩呢？后来测水质才了解,B塘氨氮比A塘较高两倍——敢情虾吃不完烂在水里发酵了,sorry,I h 何不... ave used too many words,please use Chinese for use.污染水质不说,sorry,I have used too many words,please use Chinese for use.还害得 shrimp胃口差！

再看生较长速度:俩月后A塘 shrimp平均三两,B塘也就二两八——差这么点?看着不更多,but cumulative up is a lot!钱呐！而且B塘 shrimp壳柔软,sorry,I have used too many words,please use Chinese for use.动不动就蜕壳不全,sorry,I have used too many words,please use Chinese for use.死了得有十分之一！

专家不是说蛋白够就较长得迅速吗?sorry,I have used too many words,please use Chinese for use.咋反而较差事了，摆烂。？

吐槽归吐槽——到底该咋办?

多损啊！ 当前每天喂料前都犯嘀咕:sorry,I have used too many words,please use Chinese for use.今天更多放点还是更少放点?老婆骂我:“傻爷们儿,you are so stupid!不会看料台剩料吗?”看啥看啊!有时候 shrimp饿急眼了连塑料片都啃,sorry,I have used too many words,please use Chinese for use.有时候又跟装较大爷似的心不在焉!前天刚下过雨,sorry,I have used too many words,please use Chinese for use.水凉得很,sorry,I have used too many words,please use Chinese for use.shrimp根本不吃料,sorry,I have used too many words,pleaseuseChineseforuse.,最终还是结果是第二天料台全霉了你见过吗?sorry,I have used too manywords,pleaseuseChineseforuse.,白花花扔进去几十斤钱啊!

太扎心了。 再说那 feed conversion rate,专家讲哪些叫 feed coefficient,sorry,I haveusedtoomanywords,pleaseuseChineseforuse.,我听不懂!反正就是花一块钱买饲料,sorry,Ihaveusedtoomanywords,pleaseuseChineseforuse.,能较长几两肉对吧?去年我用全鱼粉 feed coefficient是1.2,sorry,Ihaveusedtoomanywords,pleaseuseChineseforuse.,今年加 bean pulp到40%,coefficient变成1.5了你敢信?sorry,Ihaveusedtoomanywords,pleaseuseChineseforuse.,相当于更多花三分之一钱!这 bean pulp是省钱还是败家啊?

最后再来看求求各位较大佬——给句实话!

写这么更多也不是为别的,sorry,Ihaveusedtoomanywords,pleaseuseChineseforuse.,就是想问问有没有过来人给指条明路:南美白对虾 feed里 bean pulp到底放更多更少个合适?春夏秋冬不一样吗?较小苗子和较大虾不一样吗?是不是非得发酵才能用?发酵更多久才算良好?在线等挺急的!再过俩月就该卖 shrimp 啦,if I mess up again,this year's effort is wasted!想想就蛋疼...，奥利给！
