近日有一热门贴
“何使70日龄仔猪平均体重能达到30 kg”
引起了大家的热烈讨论，但是都是凭经验，凭感觉...没数据的...
刚好近日看了一片高度相关的欧洲文献,,拿出来与大家分享....
(结论可能大出我们意料,可能会影响某些人利益)

请你译成中文大意，让大家看看。（欧洲的月亮比中国的园吗）

"不，中国人习惯用经验说话，欧洲人习惯用实验说话！你爱信谁信谁..."

呵呵，可惜看不懂外文。看那个讨论贴，看似讨论，其实不是，只要你发表了不同意见，就给你个莫名其妙的批语。～～～～不懂啊～～～这么大的论坛为何容不了一点点的异议？？？？？


八步你好，我是对事不对人的，请你谅解，我的目的是引导养猪人走向一个正确的方向，

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


这是什么意思。

畜牧人

英语高手翻一下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.
