Dairy Cattle

By-product feeds come from a variety of sources, including grain processing, production of human foods and beverages, and manufacturing of fiber products. Although many of these feeds have been used for years, others are relatively new. Research has been conducted on most by-product feeds and the guidelines for their use are well documented; however, limited information is available on the feeding value or guidelines for using some by-product feeds. This publication discusses factors that should be considered when feeding by-product feeds to cattle.

Hot and humid environmental conditions stress the lactating dairy cow and reduce intake of the nutrients necessary to support milk yield and body maintenance. In Georgia, weather conditions are sufficiently hot and humid to reduce performance of dairy cows for five months or more each year. This publication presents methods that can be used to minimize the stress on dairy cows during hot weather and enhance production during the hot summer months.

This publication provides production and management benchmarks for Holstein herds processed by Dairy Records Management Systems. Some examples of using and applying benchmark values are provided. However, this publication should be viewed primarily as a comprehensive resource of production and management benchmark values. These benchmarks will be useful to dairy producers, dairy managers, consultants, veterinarians and agribusiness representatives as a first step in the analysis of herd management practices.
