Callum is currently on a 12 month placement with the Wynnstay dairy team from Harper Adams University. At university, he is studying a 4 year course in Agriculture with Animal Science, offering a broad scope of agricultural modules. Although not from a farming background, Callum has a keen passion for dairy nutrition and aims to bring new and innovate ideas to the industry.
Whilst on placement with Wynnstay, Callum has completed his FAR training as well as Cow Signals training to develop his skills. Callum is really enjoying his placement and has been involved with different projects including assessing the impact of mycotoxins on dairy cows for the 2024 maize harvest and carbon foot-printing feeds.
A successful turnout requires careful preparation to prevent health issues and ensure animal well-being. A gradual transition from winter feed to lush pasture is essential, allowing the rumen to adapt and prevent digestive upset.
Mineral supplementation, particularly magnesium, is crucial during the spring grazing period amongst other seasons to avoid deficiencies like grass tetany, also referred to as grass staggers. Well-maintained pastures with adequate grass and water, coupled with close health monitoring, contribute to a smooth turnout, minimising stress and maximising health and productivity.
A survey carried out by Wynnstay and Alltech involved the mycotoxin analysis of fresh maize silage from farms across England and Wales.
Several samples were collected and analysed using the Alltech 37+ mycotoxin test which identified the differing types and concentrations present in the maize silage. The results also predicted the milk yield reduction and somatic cell count increase as a result of feeding contaminated maize silage.
Fluctuations in weather conditions across the UK have correlated with high levels of mycotoxins present in maize silage, particularly that of Fusarium mycotoxins. The contamination of animal feeds and forages can negatively impact cow health and performance.
