镇家之宝——“和平猪”

【简评】 哈哈，和平猪，没听说过吧!别看它“只有乒乓球大小”，可居然是我家的“镇家之宝”哩！这不仅因为它的造型滑稽、可爱，更因为它代表着“我”对妈妈的歉意和爱。坦率、真切的情感，是点石成金的魔棒，它让小小的“和平猪”变得沉甸甸的啦!

说“咸猪手”

现在许多报刊、网络媒体中都用“咸猪手”一词来指轻度性骚扰。心理学家们认为“咸猪手”属于性变态的一种，心理学中的标准术语称之为“摩擦癖”，是指习惯性和癖好性通过接触或摩擦异性身体而获得快感的一种性变态，由于通常在拥挤场合发生，因此也称“挤恋”。那么“性骚扰”怎么会被称为“咸猪手”呢？其实这是有典故的。相传安禄山给杨玉环当干儿子，一日杨玉环为其擦洗，禄山抓其乳。此乃天宝遗事，后人以为“性骚扰”之前驱，称之为“禄山之爪”。可以说“禄山之爪”应该是现在广为使用的“咸猪手”一词的滥觞。因为安禄山本人身形庞大肥胖，多称其为“猪”。这在文献中多有提到，如：     

应用荧光定量PCR对PCV2在不同类型猪群血液中感染情况的调查

应用荧光定量PCR对某规模化养猪场340头份不同类型猪群猪只血液中PCV2感染的情况进行了调查。结果表明,所有被检测的猪群均存在PCV2感染,不同类型猪群的感染率为100%,全场猪的平均感染率为76.8%(261/340)。其中,生长肥育猪群PCV2感染率最高为90%,而种公猪群感染率最低为30%。在病毒荷载量方面,整个猪群的血液中病毒荷载量处于103~104copies/μL之间。     

母亲喂猪

时读梁实秋先生的散文《猪》,不理解先生洞彻人生的感悟,却对其描绘的女佣喂猪一节记忆扰新。买猪时“她眉开眼笑,抚抱不止”。一日三餐,“食不厌精,脍不厌细”。稍长,观我母亲喂猪,比先生笔下的人物有过之而无不及。

Evaluation of the effect and profitability of gene-assisted selection in pig breeding system

Objective:To evaluate the effect and profitability of using the quantitative trait loci (QTL)-linked direct marker (DR marker) in gene-assisted selection (GAS). Methods: Three populations (100, 200, or 300 sows plus 10 boars within each group) with segregating QTL were simulated stochastically. Five economic traits were investigated, including number of born alive (NBA), average daily gain to 100 kg body weight (ADG), feed conversion ratio (FCR), back fat at 100 kg body weight (BF) and intramuscular fat (IMF). Selection was based on the estimated breeding value (EBV) of each trait. The starting frequencies of the QTL's favorable allele were 0.1, 0.3 and 0.5, respectively. The economic return was calculated by gene flow method. Results: The selection efficiency was higher than 100% when DR markers were used in GAS for 5 traits. The selection efficiency for NBA was the highest, and the lowest was for ADG whose QTL had the lowest variance. The mixed model applied DR markers and obtained higher extra genetic gain and extra economic returns. We also found that the lower the frequency of the favorable allele of the QTL, the higher the extra return obtained. Conclusion: GAS is an effective selection scheme to increase the genetic gain and the eco- nomic returns in pig breeding.

遛猪

暑假,我去乡下奶奶家玩。一天,忽然厌倦了平日里玩的那些游戏,正在无聊之际,忽然听到“咯咯咯”“嘻噜噜”“嘎嘎嘎”的声音,一声赛过一声,仿佛在对我说：快来找我们吧。     

小猪扑满

婴儿室里有好多好多玩具,柜橱顶上放着一个储钱罐,它是用陶土做的．外形是只小猪。不用说,它的背上也有一个细长的小孔．这个孔口后来又被人用刀挖大了一点儿,好让银币电可以塞进去。的确,除了这多铜钱之外,里面已经有了两块银币,
