Improving milk production efficiency by using feed additives.

Farmers can achieve efficient milk production by investing in high quality genetics, but this can depend on the maintenance of high-quality rations. Evidence from trials and practical experience indicates that a reliable and cost-effective way of earning more profit from cows' milk is through optimizing feed with the right additives. This is important for farmers not only to ensure that milk production is profitable, but also to ensure optimal health and well-being for cows. Longer productive life in cows using ß-carotene; A longer productive life is associated with low culling rates and high fertility. Regular breeding can be helped by ß-carotene, a plant pigment that acts as a vitamin to support fertility in dairy cows. It accumulates in the ovaries and participates in the synthesis of the hormones oestrogen and progesterone, both of which are important for ovulation and for safeguarding the embryo. Trials conducted worldwide show that optimal dietary levels of Rovimix ß-carotene increase conception rates and lower the number of abortions. Pregnancy rates for first inseminations in a practical farm trial conducted in France increased by almost 40% in ß-carotene supplemented cows. Calving intervals were reduced by 27 days and milk yield increased by more than 400 kg per cow and lactation. The correct supplementation of ß-carotene in rations leads to an improvement in cows' fertility, health and welfare. Other recorded advantages include more regular ovulation, better foetal health and reduced incidence of retained placenta; as well as better calf health. Health issues such as mastitis can also lead to losing otherwise productive cows. Vitamin E is an important feed additive for the natural control of mastitis. Optimal levels of this vitamin (which cannot be synthesised by the cow) in pre-calving and immediate post-calving rations has been proven to increase immune system resistance to mastitis infection, reducing mammary infections at calving by up to 80%. Clinical and sub-clinical mastitis remain among the biggest drains on dairy profitability (Table 2). Supplementing rations with vitamin E, such as Rovimix E, has proved cost-effective and efficient in combating this serious problem. Correct amounts of vitamin E have also proved to decrease the duration of mastitis in infected cows by as much as 50%. There are also clear advantages gained from boosting dairy cow rations with biotin. Evidence suggests that getting the right additives to optimize feed can lead to increased animal health and well-being, production efficiency and increased income on the dairy farm. Longevity is key for efficient milk production and lifetime performance depends on healthy cows, which depends on their diet. source all about feed)
