Nutritional muscular degeneration in young heifers.

Young heifers with nutritional muscular degeneration had relatively low serum tocopherol values despite being on pasture which contained high levels of vitamin E. One possible explanation may be that vitamin E was destroyed within the rumen, another that the clinical symptoms arose very soon after turning out the animals.

[The effects of feeding NaOH-treated straw to dairy cows with special reference to acid-base balance and ruminal function (author's transl)].

Four moderately yielding cows were for 9 weeks given 4.8 kg dry substance of unneutralized, alkali-treated straw and 150 g urea, implying a great surplus of Na and alkali. With the exception of tympanitis on one occasion, no symptoms of disease were found. In spite of subfeeding with protein, no evident reduction in yield occurred during the experimental period. The rumen function was not negatively influenced by the excess of Na and alkali. The Na content in blood serum increased during the experimental period. At the same time there was an increase of bicarbonate and base excess in arterial blood. The alkalosis was, however, only mild and well compensated.

[The effects of feeding NaOH treated straw to dairy cows with special reference to the reaction of the kidneys (author's transl)].

Fattening bulls were given alkali-treated straw during 5--7 months. The daily intake of Na was 10 times greater than the requirement. The daily increase in body-weight was very high (1571--1898 g per day). No negative influence on animal health was recorded. The size of the kidneys did not increase, nor were there any histopathological abnormalities which could be attributed to the overfeeding with Na.
