Healthy cows tend to stay in the herd longer. Currently, in the United States, the average productive lifetime for a dairy cow is lactations. A cow does not mature until five years of age. Many cows are involuntarily lost during the first two months of lactation.

      The current period of reproductive decline began before the introduction of bST in , and countries in which bST is not used (Ireland, UK, and Australia) are also experiencing reproductive problems in dairy herds. In fact, the use of bST with synchronization protocols has been shown to improve pregnancy rates (Table 1). Table1.   Herd health is very important for dairy operations. Dairy cows can get sick quite easily, and are more prone to injury to their feet and udders than beef cows are, and are also prone to milk fever and ketosis after calving. In order to have a healthy dairy herd, stringent health practices must be 91%().

Effective veterinary care of dairy cattle will greatly improve a herd's productivity and keep disease to a minimum. This book is Improving dairy herds book practical guide to maintaining and improving the health of dairy cattle from birth until they leave the : Hardcover.

Book Description. Dairy cow herd health is an important and universal topic in large animal veterinary practice and farming, covering both preventive medicine and health promotion. With the move towards large scale farming, the health of the herd is important as an economic unit and to promote the health of the individuals within by: Silage success starts with planning, and the Silage Resource Guide was developed with that in mind.

Presented by DEKALB and Dairy Herd Management. Silage success starts with planning, and the Silage Resource Guide was developed with that in mind. E-unit: Improving the Dairy Herd Through Selection Page 2 tages, each has the advantage that it can improve a dairy herd.

Each has a technique or program that can identify inferior animals or promote breeding for herd improve-ment. This can eventually improve profits or productivity of the herd of dairy cattle.

Reproductive management of dairy heifers is one area in which many dairy producers can improve. Heifers are the most fertile animals in a herd and should have the greatest genetic potential. Dairy producers need to pay more attention to getting heifers bred sooner and breeding them to genetically superior bulls.

This publication describes methods for improving dairy heifer reproductive management. • Increases the number of replacement heifers. – Allows greater genetic selection intensity – Allows the sale of heifers and cows for milk production.

• Facilitates adequate culling policies. – Culling of problem cows – Younger herd better fertility, less mastitis, lameness, and increased genetic merit. Ribeiro et al.

With the use of sexed semen firmly established in the dairy industry, dairy farms have been presented with an opportunity to improve herd-level genetics through heavier culling of animals with lower genetic values, selling more offspring for commercial purposes or changing the way they manage their herd inventory by potentially using beef semen on cows with lower genetic : Robert Fourdraine.

Tropical Dairy Farming is a manual designed for use by dairy production advisors working in tropical areas, especially in South-East Asia. It aims to increase the productivity of small holder dairy farmers in the humid tropics by improving the feeding management of their livestock.

It shows how to provide dairy cows with cost-effective feeds that match small holder farming systems and.
