The annual production of useless meat, i.e., meat condemned for human consumption and meat which remains adhered to the bones and other tissues is estimated to be of the order of 23,000 tonnes. Since useless meat is an excellent source of nitrogen in poultry feed and fertiliser for tea and coffee plantations, such meat should be converted into meat meal and should not be wasted as is being done at present. 15.4 Sheep manure and Composting Sheep dropping improve the fertility of soil considerably and penning of sheep in harvested fields (sheep folding) brings in additional income to the flock owners. 477
16. Sheep Records It is essential to maintain the necessary records at an organised sheep farm to know about inputs and outputs. This will help in working out economy of sheep production per unit of area. The recording system is required to be simple, accurate capable of collecting the required information and finally kept upto date. The data collected should not be kept but should be used for proper analysis. In sheep growth rate, feed conversion, wool quality, dressing percentage are highly heritable characters. Prolificacy, milking capacity and fleece weight are characters of low heretability. More profits can be obtained if more attention is paid to characters of high heretability. Having decided his breeding prograrnme, a farmer must then choose his parent stock. Good record should identify the offspring with the parents. They should also give date of birth, sex and final disposal of individual. This information together with desirable confirmation is the basis upon which selection for flock improvement should be rnade. There should be a system for ear marking, tattooing and or tagging. In case of short ear breeds, tattooing on inside of thighs or tails be practiced. A combination of tattooing and tagging is desirable. Following data/ observations are of great help at an organised farm: i) Livestock inventory This register gives information about the individual identification, parentage and date and reason for sale or culling. ii) Wool weight and quality Wool evaluation should be limited to greasy fleece weight of each clip, staple length at a particular site, average fiber diameter, medullation percentage, visual assessment of fineness and making careful examination of undesirable characters such as black fibers or coarse fibers. iii) Growth records Body weights at birth 3, 6, 9 and 12 months of age are important. Birth weight is related with vigour, survivability and growth rate. Weaning weight is used to measure total lamb production of an ewe. Six month weight is correlated with market and yearling weight and is highly related to adult weight and ewe productivity. Body weights of each lamb are required to be correlated to age, sex, type of birth, season and age of dam. iv) Prolificacy Twin producing ewes are more prefitable than single produeing ewes excepting in areas where grazing conditions are poor. v) Health Information on causes of death and ineidenees of diseases helps in planning prophylactic health programme. In addition to above data, the following records should be kept properly. 1) Livestock account record 2) Breeding record 3) Lambing record 4) Shearing/wool yield record 5) Mortality record 6) Sale of animals and wool record 7) Purchase of livestock. medicines and equipments record. 16.1 Guidelines for recording of Data All recordings should be done by the Farm Manager or Technical Officers available to him. 16.1.1 Body weights The body weight should be recorded at birth and after every 7 days upto 28 days and thereafter every 15 days upto 268 days and thereafter every 30 days upto 35 8 days.
