La detección de celo es el primer paso para hacer que un animal se preñe. De acuerdo con los registros de la Asociación Nacional para la Información de Hatos Lecheros (DHIA por sus siglas en inglés) los productores en Georgia solo ven un tercio de los celos. Los celos perdidos son uno de varios factores que contribuyen a intervalos largos entre partos. Al aumentar el número de celos observados es posible disminuir el tiempo entre partos.
[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.]

Problem identification is the first step in establishing objectives and goals to improve reproductive management in a dairy herd. Management is determining what must be done and achieving results through the efforts of yourself and your employees. Use the following worksheet to evaluate herd reproductive performance and set goals to improve your breeding strategies. Then develop a tactical plan to achieve these goals using the second worksheet. List those involved on your management team and their responsibilities.

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.

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.

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.

This publication describes dairy herd synchronization programs will help improve your reproductive management efficiency. Try the one that fits your management system the best. Both estrus and ovulation synchronization programs will help get more animals bred more efficiently. Feeding open animals extra days can be costly to producers. Identify open animals and pick the best breeding alternative for your operation.

Goats are the most widely-dispersed meat animals and have been raised for centuries to provide meat, milk, fiber, cashmere and leather. Due to their small size, adaptability to harsh environments and availability, they have been more popular in nations lacking refrigeration, animal management skills and modern transportation. This publication deals solely with Spanish or meat-type goats in Georgia and covers their history, selection and management—from predator and disease control to reproduction and marketing.

Drought does not develop overnight but progressively over time. Proper management during a drought period can make or break a producer’s ability to stay in the cattle business. One main concern during a drought period is feeding and nutrition of the cow herd. Several problems could arise due to drought conditions. A good producer should stay alert for warning signs and avoid potentially damaging situations.
