The Wynnstay Calf and Youngstock section of the AgriHub is written by specialist in the field. Our lambing news and advice is created to prepare you for the lambing season, making sure that not only is you lambing shed ready but also both lamb and ewe health is managed.
Our team of calf specialists are highly experienced in the field of calf rearing, their blog posts offer calf rearing advice and news for both dairy and beef farmers. Our calf news section looks at calf housing, feeding and health. It also offer advice on how to improve profits and margins on farm.
Wynnstay customer, Andrew Wallis, from Dorset, discusses his experience following a switch to Wynnstay's Elixir Calf Milk formula.
One in five sheep producers are still cross fostering triplet lambs onto single-bearing ewes and about 30% are continuing to bottle feed orphans. This is despite the significant extra labour required to carry out both traditional rearing practices.
With spring calving fast approaching, kickstarting one of the busiest, most demanding time of year, being properly prepared can relieve some of the stress for farmer, cow and calf.
Rearing heifers are a sizeable investment to a dairy enterprise, with rearing costs not being recouped until the cow reaches their second lactation. Studies carried out by AHDB show that on average 17% of milking heifers exit the herd before their second lactation (AHDB, 2023).
Back at the start of 2023, the acronym ‘CALF HEALTH’ was chosen by the calf and youngstock team to base their newsletter articles on. Each letter represented a topic that contributed towards improving calf health.
Lambs are born with an immunological disadvantage due to immunoglobulins being unable to be passed through the placenta to the lamb during pregnancy, making them particularly vulnerable to diseases. During the first two hours of life the gut is 20-30% efficient at absorbing IgGs, but the capability of the gut declines to 0% after 24 hours. Consequently, it is crucial that lambs receive colostrum soon after birth in order to absorb sufficient antibodies to reduce the risk of disease and mortality.
Calf housing is a critical aspect of any dairy or livestock operation, and the choice of housing design can have a profound impact on the health and well-being of your calves. To optimise calf performance and minimise the incidence and spread of disease, there are key requirements for calf housing that must be considered.
Calf housing is a huge part of calf health and welfare, it can be the change that many systems need to improve their calf rearing. In September, DEFRA launched a £10 million infrastructure grant to fund calf housing, available to new and upgraded calf housing. Improvements such as ventilation, protection from draughts, and suitable temperature and humidity will be key areas to focus on.
Good ventilation systems are essential to reduce respiratory disease in the first months of a calf’s life.
It is estimated that the cost of pneumonia per sick calf is £42.26, with an additional cost of £29.58 per calf for the in-contact group. In turn, this reduces feed efficiency, growth rates, organ development, future milk production and an increased mortality risk before calving.
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.
