This publication provides reproduction 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 for reproduction 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.

Early identification and diagnosis of reproductive problems through a herd health program are an essential part of successful dairy management. A cow must be pregnant by 85 days postpartum to achieve a 12-month calving interval. This is the backbone of sound reproductive management in an economical dairy business. Many factors during the dry period, parturition and early lactation can lower reproductive efficiency. These include mastitis, cystic ovaries, lack of body condition, retained placentas and anestrus. These postpartum problems lengthen calving intervals and affect reproductive efficiency.

When the time comes to examine a herd’s dairy reproductive management program, producers often want to discuss low conception rates. In most cases, however, inadequate heat detection is the much greater reproductive problem. Heat detection is the first step to getting an animal bred. According to DHIA records, producers in Georgia are only seeing a third of their heats. Missed heats are one of several factors that contribute to long calving intervals. By increasing the number of heats observed, it is possible to shorten the interval between calves.

Resolviendo Problemas Después del Parto
La identificación y el diagnóstico temprano de problemas reproductivos relacionados a nuestro programa de salud del hato es una parte esencial de un manejo eficiente de nuestra producción lechera. Muchos factores durante el periodo horro (seco), el parto y la lactancia temprana pueden disminuir la eficiencia reproductiva. Estos incluyen la mastitis, quistes ováricos, falta de condición física (body condition), placentas retenidas y anestro. También, ciertos desordenes pueden ocurrir simultáneamente. Por ejemplo, una vaca con fiebre de leche frecuentemente padece de una placenta retenida. Estos problemas post-parto alargan los intervalos entre partos y afectan la eficiencia reproductiva.

Dairy Genetic Benchmarks
This publication provides genetic benchmarks for Holstein herds processed by Dairy Records Management Systems. Examples for using and applying benchmark values are provided; however, this publication should be viewed primarily as a comprehensive resource of genetic benchmark values. These values will be useful to dairy producers, dairy managers, consultants, veterinarians and agribusiness representatives as a first step in the evaluation of the genetic program of a herd.

This guide to housing preweaned dairy calves is a resource for both farmers and youth participating in livestock projects. Housing can greatly impact the health and growth of dairy calves. Attention to factors that influence feed intake, comfort, and health are necessary for optimum growth and performance of calves, with long-term implication for their future productivity.

Selecting commercial dairy heifers and monitoring their growth can be difficult for many farmers and youth exhibitors. The way in which farmers are achieving production efficiency is highly variable from farm to farm, so this publication provides guidance on the conformation and growth parameters of commercial heifers found to be most ideal for future production efficiency.
