Glanvac® 6S provides protection against Cheesy Gland (CLA) and the main clostridial diseases with the added benefit of correcting selenium deficiencies. The prevention of Cheesy Gland in sheep flocks improves wool production and increases the quality of sheep meat. The clostridial diseases prevented include Tetanus, Pulpy Kidney, Blackleg, Black Disease and Malignant Oedema. Selenium is an essential trace element that is vital for wool production, growth and fertility. Selenium deficiencies in sheep result in reduced wool production and growth rates, ill thrift, infertility in ewes and death of young lambs due to white muscle disease. This product may be used in the Glanvac+Eryvac Dual Vaccinator and reused for 30 days after opening after following label instruction.
