The most universal mineral supplement needed by farm animals in East Africa is salt (sodium chloride) which should be fed at the rate of 0.5 per cent of the dry matter of the total ration. The supply of phosphorus is insufficient in a number of areas (particularly in the dry season) to maintain an optimum level in the blood of growing or lactating Zebu cattle. The supply from dry season grazings may also be below the requirements of heavy milking imported or grade cows. Whilst shortage of calcium has not been reported in Zebu stock, it is probable that intensively managed high yielding cows require lime supplements. Lime should always be included in pig and poultry rations and for heavy-laying birds should be provided in separate containers. Lime should also be included in the concentrates fed to horses. The iron, copper, cobalt group of "trace" elements is probably deficient in certain areas but a full survey of these possible deficiencies has not yet been conducted. In all cases of doubt, or where there is a dry season anaemia, or where there is any suggestion of wasting diseases or stringy wool in adults or inco-ordination, unthriftiness and high mortality rates in young lambs, these minerals should be incorporated in the normal mineral supplement. General purpose mineral mixtures for ruminants should contain parts of lime, 14- parts bone meal and 1 part of salt, whilst for pigs, poultry and horses the lime should be increased to 2 parts to 1 part of bone meal and 1 part of salt. Where it is desired to feed "trace" elements, 11 lb. of a mixture of 10 parts ferrous sulphate, 3 parts copper sulphate and 1 part cobalt sulphate should be mixed with 100 lb. of the general purpose mixture.
