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 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.

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.

This guide is designed to help you improve your reasons for your placings in dairy cattle evaluations. Slowly incorporate new terms into your oral reasons and your ability to describe what you see will continue to improve. Concentrate on what you see instead of what you don’t see. You only have 2 ½ minutes to justify your placings. Use I.D. points, and Practice! Practice! Practice!

Using incorrect A.I. techniques can lower the overall success rate of the A.I. breeding program. Most producers learned correct semen handling techniques and insemination procedures at one time; unfortunately, many have developed bad habits that have lowered their success rates. This publication reviews proper procedures that should help eliminate some of those common mistakes.

This brief management guideline provides producers with specific management tactics that may minimize the potential for short- and long-term problems. These tactics, categorized in order of early, advanced, and severe drought stages, are based on specific characteristics including water loss, forage growth, and rainfall.

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.

Adjust rations for the dry matter (DM) content of each feed, especially when wet feeds, such as silage, are fed. Small changes in the DM content will change the nutrient profile of the ration. The potential results of not monitoring the DM content of wet feeds and adjusting rations accordingly are a combination of problems including decreased animal performance and feed efficiency and increased health problems and feed cost.

Research has demonstrated that proper dry-off methods are vital in promoting udder health during the nonlactating period and at calving. For high producing cows, it may be necessary to decrease dietary energy over the last 1-2 weeks of lactation by increasing fiber and eliminating grain. Abrupt cessation of milking is probably as good as intermittent milking with a diet change for low and medium producing cows; however, intermittent milking is recommended for high producing cows to decrease milk yield and minimize leakage at dry-off, which could lead to mastitis. First lactation cows should be given a 50- to 60-day dry period, but multiparous animals fare well with a 35- to 45-day dry period. Selective dry cow therapy with non lactating cow antibiotics plus teat seal is as effective as blanket dry cow therapy with non lactating cow antibiotics plus teat seal for cows with SCC less than 200,000/ml. However, blanket dry therapy with both products is recommended for cows that dry off with greater than 200,000/ml. It is important to follow recommended infusion techniques to preserve the protective components of teat canal keratin and the sphincter muscle. And lastly, use of coliform vaccines will enhance immunity over the dry period and reduce clinical coliform mastitis in early lactation. This publication address these topics in more detail in order to help producers prevent mastitis in their dairy herds.
