This article from researchers from Cornell University and Germany describes the individual, seasonal and herd-level variability of colostrum production and summarizes the association between animal individual factors – such as parity, sex of the calf, calf birthweight, as well as indicators of the cow’s metabolic status – and the yield and composition of colostrum.

As with all areas of dairy operations, increasing efficiency – in this case of feed in the rumen – deserves attention because when it is improved, gains can be seen beyond the area of focus, not to mention in sustainability (this includes economically) as well.

Profitable livestock production requires many quality management skills that all impact the technical results.

At the annual Animal Nutrition Conference of Canada, conference speakers shared diverse perspectives on some of the most pressing issues facing the livestock feed industry, ranging from the emergence of lab-grown proteins to the quest for net zero and the role of trace mineral additives in sustainability.

If we consider how plants can help our heifers and cows conquer that daunting transition period, there may be more than simply forages, in terms of plants, to consider. Let us dig into the world of phytochemicals.

It is essential to reduce variation when dealing with what represents – on average – 45% of the cost of operating and is a major source of stress for both the animals and employees.

Feed costs account for more than 45% of production costs and approach nearly 60% with high feed costs. Obviously, dairy income is directly proportional to milk volume, composition and quality produced on the farm.

All we have to do is balance the ration to maximize fat, right? Regarding the number of variables involved in ration formulation, few diets are ever truly balanced. Consider the word “optimized” instead. Let’s look at several key nutrients that must be optimized for maximum butterfat production.
