Scott Fritz, K-State Clinical Assistant Professor of Toxicology, joins the podcast to discuss replacement heifers and compounding. They explore factors to consider when deciding to save or sell replacement heifers, including market situation and genetics. They also discuss the use of soybean hay as animal feed and potential concerns, such as fat content and mold. Additionally, they touch on the impact of pesticides on animals and forage crops and emphasize the importance of label reading for safe use.
Factors such as time, labor, and resources, as well as genetics and animal disposition, must be considered when deciding whether to save replacement heifers.
Soybean hay can be a good feed resource if cut at the right time, and proper drying is necessary to prevent mold development and ensure safety.

Saving Replacement Heifers: Factors to Consider
Deciding whether to save replacement heifers depends on factors such as time, labor, and resources. The cost of raising replacement heifers and potential health risks must be considered. Genetics, animal disposition, and herd expansion or contraction also play a role. It is crucial to evaluate the impact on average cost per cow in the long term. Utilizing decision tools provided by land grant universities can help compare buying versus raising replacement heifers.
Feeding Soybean Hay: Nutritional and Toxicological Considerations
Soybean hay can be a good feed resource, especially if cut at the right time. The nutritional quality of soybean hay decreases with maturity, and diluting it might help improve its digestibility. It is important to avoid excessive fat content that can reduce feed intake and digestibility. Bloat is less of a concern with dried soybean hay compared to grazing fresh soybeans. However, proper drying is necessary to prevent mold development. In terms of toxicology, it is essential to refer to the label instructions for any grazing restrictions or prohibitions due to insecticide or fungicide applications. Testing for nutrient analysis and nitrates can provide further insights.
Understanding Pharmaceutical Compounding and its Applications
Pharmaceutical compounding involves customizing drug products by modifying their formulation. In veterinary medicine, compounding is commonly done for small companion animals but becomes more complex for food animals. The primary consideration in food animal compounding is to exhaust all available labeled drug options before considering it. The stepwise path for food animal compounding includes using labeled products for the target species and other food animal or companion animal species, as well as considering compounding from labeled human or companion animal drug products. Compounding from bulk chemicals is not permissible due to residue concerns. The necessity of compounding for toxic antidotes may be a special case but should still follow legal guidelines set by regulators.
