關于“ 如何使70日齡仔豬平均體重能達到30 kg ”的思考

近日有一熱門貼
“何使70日齡仔豬平均體重能達到30 kg”
引起了大家的熱烈討論，但是都是憑經(jīng)驗，憑感覺...沒數(shù)據(jù)的...
剛好近日看了一片高度相關的歐洲文獻,,拿出來與大家分享....
(結論可能大出我們意料,可能會影響某些人利益)
聲明:
        1.文中觀點非本人觀點.
         2.你有權不同意我的觀點,但請尊重我的發(fā)言權.
        3.你可以罵我,但罪不及家人!

請你譯成中文大意，讓大家看看。（歐洲的月亮比中國的園嗎）

"不，中國人習慣用經(jīng)驗說話，歐洲人習慣用實驗說話！你愛信誰信誰..."

呵呵，可惜看不懂外文。看那個討論貼，看似討論，其實不是，只要你發(fā)表了不同意見，就給你個莫名其妙的批語?！欢　@么大的論壇為何容不了一點點的異議？？？？？


八步你好，我是對事不對人的，請你諒解，我的目的是引導養(yǎng)豬人走向一個正確的方向，

Effect of Pre-and Post-weaning
Nutrition and Management on
Performance of Weaned Pigs to
circa 35 kg.


這是什么意思。

畜牧人

英語高手翻一下The objective of this project was to examine the factors
affecting performance (growth rate, appetite, feed conversion efficiency)
of pigs in the stage from weaning to 35 kg liveweight.
The study involved three stages, creep feeding during the suckling
period, management during the first weaner stage (c. 4 weeks
from weaning or 6 kg to 15 kg liveweight) and management during
the second weaner stage (c. 15 kg to 35 kg liveweight.
Creep feed intake before weaning was low c. 2.5 to 3.0 kg
per litter but where it was consumed the response in terms of feed
conversion efficiency was good with litter weight increasing in
weight by about 1.1 kg for each 1 kg creep consumed. Milk
replacer in liquid form was very readily consumed but its preparation
and feeding is very laborious. Weaning weight was poorly
related to post weaning performance and weaning age seemed to
be more critical which is probably a reflection of the greater
maturity of older animals.
In the first weaner stage, feeding of cooked cereal containing
diets was found to have little benefit in pig performance.
Acidification of feeds is likely to have only a minor influence on
pig performance. An experiment on choice feeding of starter and
link feeds did not confirm that smaller pigs require a higher quality
diet and, in a choice situation will eat a greater proportion of the
more nutrient dense diet.
In the second weaner stage, comparison of three commercial
weaner feeds with a cereal based control diet showed good performance
on all four diets. Pigs fed a high lysine weaner diet grew
better in the weaner stage but by slaughter those pigs fed the low
lysine weaner diet, after all pigs were fed a common finisher diet,
had overtaken them. The high lysine group did, however, have
leaner carcasses.
Residual effects of early nutrition need to be investigated in
more detail including the effect of pregnancy feeding on prenatal
development and the relationship between prenatal growth and
postnatal growth, in particular development of muscle.
