Zinc Content of Certain Feeds, Associated Materials, and Water¹

Dairy Department, University of Georgia, Athens

ABSTRACT

It has been shown that cattle require zinc (2, 3). However, the practical importance of zinc in ruminant nutrition has not been established and its metabolism is limited.

One of the handicaps in planning nutrition studies is the lack of reliable data on the zinc content of most feeds. Thus, one of the purposes of this paper is to publish data on the zinc content of several feeds and other materials which might be used in future studies. Also, this information will aid in determining the practical importance of zinc in ruminant rations.

Zinc analyses were made by the dithizone procedure developed by Verdier et al. (9). These results are summarized in Table 1. Each of the samples was a composite from one or more different lots of material and thus represents an independent estimate of the zinc content of the ingredient or material. Every sample was analyzed two or more times.
