In our latest short, ‘bite-sized’ podcast, we start a two-part series on the basics of protein in ruminant nutrition. This first episode explains what determines a ruminant animals' demand for protein, and explains why protein requirements differ across animal classes with different physiological states (e.g. lactation, pregnancy). We break down the fundamentals of amino acids and their role in building protein, and introduce the concept of ‘crude protein’ (CP) as reported by feed testing labs, highlighting where CP values fit into practical feed planning.

How do we wean calves from liquid milk or calf milk replacer (CMR)? For each and every calf weaning set up, there’s no doubt a broad range of different ways to wean calves - and no two systems will be the same!

In this our latest Rumen Room Podcast, we explore some of the different approaches to weaning dairy calves (heifer replacements and dairy beef) off milk or CMR. The sudden stopping of milk feeding isn’t an option – being way too stressful on the calf! What’re some ways to reduce the stress on the calf associated with the weaning from liquid feeds? There should be something for everyone in this, our latest podcast – enjoy!

All the hard work has been done, your four day old calves have grown well and it’s time to think about weaning the calves from milk or calf milk replacer (CMR). Our latest Rumen Room Podcast steps through the range of factors that collectively give us guidance to when a calf is ready to wean. There're many factors to think about, including the age and liveweight of the calf, daily liveweight gain, perhaps the wither height of the calf as well as rumen capacity and rumen function. Topped up of course by a healthy dose of your very own “gut feel” and intuition around if a calf is ready to wean or not.

Keep an eye (ear?) out for part two of this weaning-themed calf podcast - this will follow shortly, focusing on the different approaches that we can take to the weaning process itself.
