We produce Hi-spec poultry vitamins, minerals and feed additives, plus essential health products for domestic & commercial poultry.

Thank you for visiting our website. The AviVit range contains a collection of premium quality, concentrated vitamin and mineral supplements as well as other essential items for maintaining optimum health in all poultry. Our products are used by professional and domestic poultry keepers for layers, broilers, breeders, chicks and growers. Philip and Janet Lee-Woolf have the benefit of extensive experience in commercial egg production, having founded Clarence Court, Britain’s most successful and innovative niche egg business, in 1988 and breeding their popular Mabel Pearman’s Burford Brown and Old Cotswold Legbar chickens for domestic use during the past thirty years. This ‘hands-on’ experience and the knowledge gained over four decades, from breeding and keeping traditional poultry, provides a strong base for customer confidence in our products. AviVit offers the preferred choice in poultry health products to dedicated and discerning poultry keepers looking for better than average products and service.

Vitamins are a group of organic compounds that your hens require in small quantities. Despite the low requirement levels, vitamins are essential for normal body functions, growth, and reproduction. A deficiency of one or more vitamins can lead to a number of diseases or syndromes. We produce products to suit all situations.

Vitamin deficiencies can be due to a variety of reasons, including, inadvertent omission of a vitamin pre-mix from a bird’s diet, or vitamin destruction in feed due to storage time, humidity, or temperature. Feed supplied in plastic bags can suffer condensation problems causing mould or destruction of some nutrients if exposed to the sun or high temperatures.

Most poultry feed is sold with a three month ‘use by’ date on the ingredients label. The date should be checked before purchase, as some vitamins start to degrade a few weeks after manufacture.

Deficiencies don’t show immediately, but problems with the B vitamins appear first, whereas, deficiencies with fat soluble vitamins that are stored in the body, take longer to affect the bird. Additional vitamins are often needed during times of stress, or during and after an illness.

An adequate supply of minerals and vitamins in the diet is an important part of good poultry keeping. The feeding of a vitamin and mineral deficient diet can produce numerous health problems, including death in some cases.
