| Summary, etc. |
Six elephants working in four different private timber mills in Trichur district were selected for the present study. Average weight of elephants estimated using formula was 4627.80 + 114.15 kg. Elephants consumed 213.00 + 3.338 kg roughages and 7.50 + 0.475 kg of concentrate. They obtained 9.721 + 0.837 kg dry matter, 3.613 + 0.075 kg DCP and 31.517 + 0.754 kg of TDN over and above maintenance requirement, which may be the amount of nutrient utilized for work performance. Elephants were engaged for three types of work in timber mills, carrying, moving/stalking and hauling timber logs. Mean draught developed during carrying was 445.095 + 22.448 kg. Elephant could be made to carry weights upto 20 per cent of their body weight on their tusk during carrying and stalking/moving timber. A new instrument called Elephant Draught Power Monitor was fabricated to measure the draught developed during hauling timber. A regression, Y = 0.7787 x – 100.69 (where Y is the draught developed and X is the weight of the log hauled) was developed from the measurements. The draught power estimated this equation was compared with the values obtained by the formula draught = load x CosƟ. It was assumed that the formula draught = load x CosƟ was not suitable for elephant draught power measurement. The average draught developed during hauling was 1779.391 + 130.386 kg. Highest maximum of weight that an elephant could be made to haul during instantaneous force development was 188 per cent of the body weight. Maximum limit of weight that an elephant could be made to haul during continuous work was 38 per cent of its body weight. Speed of work of elephants during carrying, moving and hauling was 1.333 + 0.075, 0.630 + 0.014 and 0.701 + 0.014 m/s respectively. Speed of work of elephants decreased with increase in weight of the log transported. The average horse power developed during carrying, moving and hauling were 7.116 + 0.106, 2,566 + 0.048 and 7.138 + 0.280 respectively. The average work output per day during carrying, moving and hauling were 1819.004 + 92.619 KJ, 179.718 + 5.955 KJ, 3375.373 + 16.885 KJ respectively. Maximum work output from elephant was obtained during hauling. Maximum work output (34 per cent) occurred during 8.30 am to 9.30 am in timber mills. Elephants were made to work minimum during 12.30 pm to 2.30 pm. Rectal temperature was identified as the most reliable physiological parameter which can be used as an indicator of fatigue. Maximum body temperature recorded during work was 1000 F. Maximum frequency of spraying of saliva during the entire study period was two/minute and maximum frequency of fanning of ears was 45/min. The value of rectal temperature when the elephants were fatigued was 98.60 F. Work may be stopped and elephant should be given rest before reaching this body temperature to avoid undue fatigue. Mechanised power which replaces elephant power in many timber mills has certain advantages. But use of elephant has got the advantage of utilization of renewable resources environmental friendliness and greater maneuverability during work. |
