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.

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 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.

This module describes the role of energy in the body, how much energy is contained in our foods, and how to correctly identify the key nutrient classes that our bodies require from the foods we eat. All of these components are related to the general makeup of a commercial poultry diet. The module is designed to be one in a series of publications to supply relevant educational content related to the poultry industry to agricultural teachers, STEM teachers, and the general public.

Africanized Honey Bees
Honey bees are among the most well-known and economically important insects. They produce honey and beeswax, and pollinate many crops. In spite of the alarm surrounding Africanization, these bees have not caused widespread or permanent chaos. Dramatic stinging incidents do occur, but the quality of life for most people is unaffected. Typically, the commercial beekeeping industries of Africanized areas suffer temporary decline and then eventually recover.

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.

New feed ingredients are evaluated and introduced to the feed industry every year. The evaluation process is necessary and includes feeding birds different levels of the test ingredient to estimate the maximum safe level (MSL). The MSL is usually estimated with a multiple range test, ignoring the fact that this test is inappropriate for this type of feeding trials where the independent variable is continuous. This paper describes the use of the Maximum Ingredient Optimization Workbook (MIOW) in estimating the MSL and determining the optimal combination or ingredient levels and replications for most efficient experimental design of future feeding trials. The MIOW calculates the results and the related descriptive statistics (SD, SE, Cl, and R2) based on simulation and non-linear regression models (broken-line linear and broken-line quadratic models).

An Excel workbook, Nutritional Response Determination Optimization (NuRDO). has been developed to simulate the optimal number or nutrient levels and replicates per level when planning nutritional requirement studies. With NuRDO, researchers can simulate data from what they think is the real shape of the response curve. They can then run up to 1,000 simulated experiments to see the combination of levels and replications that minimize the standard error or the requirements and other parameters for the broken-line models. SK and hyperbolic models. For example, consider the BLL model with a “true” requirement (REQ) of 5.2, a maximum of 99 units, a rate constant of 18.6 and a CV of 10%:For 5 input levels and 10 reps per level, the estimated REQ ± SD is equal to 5.196±0. 106, for 10 levels & 5 reps each, the REQ is 5.231±0 .157. The workbook can be used in this manner to determine the best combination of levels and reps to improve the chances or getting the best results possible from experiments.

Profitable cattle marketing means producing the most profitable calf, selling through the most profitable market outlet and pricing at the most profitable time. Unfortunately, most cow-calf producers simply sell their calves. Marketing means choices on how or what to put on the market, where to market and when to price. The first step in becoming a cattle marketer is to recognize all your alternatives and evaluate each in light of potential cost and returns, selecting the most profitable rather than the most convenient alternative.
