Methionine is an essential amino acid for dairy cows, but it is often undersupplied in typical rations. It is considered essential because cows cannot synthesize enough methionine to meet their needs, so it must be supplied by what they digest. 

As we move further away from harvest and into storage and feedout, mycotoxin risk does not disappear. In fact, warming temperatures and variable storage conditions can favour the growth of storage moulds such as penicillium. 

Modern research clearly shows that metabolic dysregulation during the transition period, particularly involving protein supply and inflammatory tone, strongly influences early lactation performance, disease incidence, reproductive outcomes and overall herd profitability.

From a nutritionist’s perspective, feed inventory is more than a count of tonnes; it’s the backbone of ration consistency, herd health and overall farm profitability.

Researchers assessed the effects of municipal tap water compared with purified water on calf performance and health.

Vegetable oils, particularly oils that are high in monounsaturated fatty acids such as canola oil, have been shown to reduce methane output and improve energy efficiency. In addition, some secondary plant compounds can likewise modify fermentation to reduce methane production.

Low magnesium-containing mineral sources with high availability can still make a meaningful contribution to the magnesium status of your herd, and differences in solubility should be priced accordingly. Paying attention to solubility and payload ensures that every gram of mineral in the diet delivers value to the cow.
