The transfer of passive immunity in calves is defined as “the absorption of the maternal immunoglobulin, present in colostrum through the small intestine of the calf, during the first 24 hours after birth. Calves are born without any acquired immunity due to the placental structure of the cow and therefore, rely entirely on passive transfer. The colostrum absorbed by the calf activates and regulates the innate responses enabling the calf to fight infection.
Low grass silage stocks have been a significant subject of conversation this summer, stemming from the adverse impact of a dry June on grass growth.
Although we had rain towards the end of June, it was patchy. Where rain did fall, it often came in short, heavy bursts. If the ground was baked hard, this made it prone to run off. What we needed was prolonged rainfall to wet the ground so it could soak in.
For sheep, constant management of fluke is necessary because there is often no break in the grazing cycle. So, with no product persistent against fluke, a sheep treated one day can pick up infection the next if they are grazing infected pasture.
The basic requirements of a calf can be condensed into seven key words. These combine to form the points on the YoungStock Signals diamond. All six points need to be satisfied in order to achieve optimum health, welfare and production.
Manipulating photoperiods and light for the milking cows is a fairly well researched and discussed topic. However, often we forget to consider the benefits this could have for dry cows.
When it comes to selling wheat, many growers revert to selling it for animal feed, however it is important to evaluate and maximise the potential of grain in terms of market and premiums, as many could be missing out on opportunities to add value to their grain.
It is important to remember that not only group one varieties on the recommended list have the potential to offer a premium, as many group twos, threes and fours can also provide this if the specs are met, which many of them are capable of.
In Season 3, Episode 7 of the Wynnstay Agri-Hub podcast, Rob Hess one of our Senior Traders at GrainLink has joined me to discuss the potential of grain in terms of how growers can optimise quality and ultimately achieve the best price possible.
Free-range hens are frequently provided enrichment to promote foraging behaviours and try to lower the frequency of harmful feather plucking. Studies have shown that hanging ropes, a traditional enrichment method for chickens, offers very little benefit.
When growing high yielding varieties, often other agronomic features such as disease resistance are sometimes overlooked. The fungicides at our disposal today are capable of producing extremely good results, but it is important to apply as much thought to the fungicide programme and timings as to the choice of product, to achieve optimum yield potential.
Over recent years, the emphasis has moved away from reactive fungicide applications to treat visible disease in the crop, and more towards a strategy where prevention is better than cure. To achieve this, the fungicides must be applied at the correct time and early in the development of the disease, or even before infection occurs, with timing infl uenced by growth stage, weather and the variety’s disease resistance.
Alongside nine project partners, Wynnstay is pleased to be involved in the Innovate UK project ‘Dancing with daffodils’, which focuses on cultivating and processing daffodils.
Research is being undertaken to identify the potential of the incorporation of a compound found in daffodils into ruminant diets to reduce methane emissions and improve protein utilisation.
In season three, episode six of the Wynnstay Agri-Hub Podcast Alison Bond, Technical Services Manager at Rumenco and Andrew Evans, first-generation dairy farmer and Group Sustainability, Innovation and Food Supply Chain Director at Wynnstay, tell us more about the project and what it means for the industry.
Hedgehogs play a crucial role in the ecosystem by controlling insect and pest populations. They are also commonly kept as pets, and various organisations are dedicated to rescuing and rehabilitating orphaned or injured hedgehogs.
