In 1961 ttuffman (31) discussed high-level
grain feeding for dairy cows in a symposium
before this group. This paper will, therefore,
be directed primarily toward developments
which have arisen during the oast three years.
Excellent reviews on the subject have been
presented by Huffman (32), Lassiter and Brown
(37), and by Loosli (40). As might be expected,
a large amount of popular literature
on high-grain feeding has appeared, most of
it favorable (for example, 36, 57); however,
one article by Scholl (55) raised serious questions
about the practice. Some confusion appears
to exist as to the distinction between
high-level feeding, as such, and the provision
of a diet which contains a relatively high proportion
of concentrated feeds. Fortunately,
the bovine is able to tolerate wide variations
in level of nutrient intake and in proportions
of dietary constituents. It will be a purpose
of this review to examine the possible effects
of some of the extremes in both types of highlevel
feeding of concentrates.
Effect of heavy concentrate feeding on milk
production and composition. I-Iuffman's review
(31) indicated that a summary of available
literature left little doubt that high-grain feeding
resulted in an increase in milk production.
It was pointed out that cows of high potential
for production ahnost always will respond.
Ability and individuality of animals appears to
be of considerable importance, as pointed out
earlier by Bloom et al. (9). A number of reports
have indicated that significant increases
in milk production resulted when amounts of
concentrates fed were elevated (4, 7, 13, 17-20,
44). Most of the increased production was
accounted for by the greater energy content of
the diet, or by the simple fact that more total
energy was fed. In support of this concept,
Elliot and Loosli (23) fed diets in which the
level of estimated net energy (ENE) intake
above maintenance was held constant. Production
of fat-corrected milk (FCM) was not different
on diets containing 40, 60, or 80% of the
ENE iu the form of concentrates.
A number of relatively recent studies have
indicated that high-concentrate feeding resulted
in increased milk production, whereas other
research has indicated no advantage in that
respect. Murdock and ttodgson (45) reported
that about 5 lb of increased milk production

大哥大姐,帮忙翻译一篇英文文献,急,谢谢
首先,这是我的翻译习惯--括号里的是可要可不要的昂(除了你本来就用括号的),还有“\/”的前后是供你选择的。而且你这段话里面明显有几处错误昂,呵呵,有点乱。1961年,ttuffman(人名你写错了,不知道你是不是要说霍夫曼)在这个组织之前,曾在一个讨论会上讨论了关于奶牛(高度)精饲料喂养。
