Abstract: "Evaluation of economical losses due to mortality & morbidity in Marwari sheep in arid zone" have been studied using data (for Marwari, 3164) collected from CSWRI, ARC, Bikaner spread over eight years (2005-06 to 2013-14). The traits investigated were morbidity and mortality due to different diseases. The different age groups were birth to three (suckling), three to six (weaning), six to twelve (hogget) and above twelve months (adult). The diseases recorded from the farm are classified here on the basis of body systems. Significance of different classes was tested with chi-square. The overall morbidity of suckling group was 24.27 per cent. Diseases of the digestive system-I accounted for maximum number of morbidity in suckling group (MBR-I=11.50%, MBR-II=47.40%), followed by pyrexia (MBR-I=3.92%, MBR-II=16.15%), diseases of blood (MBR- I=2.65 %, MBR-II=10.94%). diseases of respiratory system (MBR-I=2.50%, MBR-I=10.29%), surgical problems (MBR-I=1.42%, MBR-II=5.86%), diseases of the digestive system-II (MBR-I=0.98%, MBR-II=4.04%), eyes (MBR-I=0.09%, MBR- II=0.39%), disease of other group (MBR-I=1.23 %, MBR-II=5.08%). The overall morbidity of weaning group was 13.29 per cent. Morbidity rates due to diseases of the eye (MBR-I=6.39% MBR-II=48.09%) was maximum followed by the pyrexia (MBR-I=1.89%, MBR-II=14.25%), digestive system-I (MBR-I=1.69%, MBR-II=12.72%), diseases of respiratory system (MBR-1=0.95%, MBR-II=7.12%), disease of blood (MBR-I=0.74%, MBR-II=5.60%), diseases of other group (MBR-I=0.74%, MBR-II=5.60%), surgical problems (MBR-I=0.57%, MBR-II=4.33%), lameness (MBR-I=0.17%, MBR- II=1.27%), diseases of digestive system-II (MBR-I=0.14%, MBR-II=1.02%). The overall morbidity of hogget group was 6.85 per cent. Morbidity rate due to diseases of the eye (MBR-I=1.94%, MBR- II=28.34%) was maximum followed by digestive system-I (MBR-I=1.76%, MBR-II=25.67%), surgical problems (MBR-I=0.81%, MBR-II=11.76%), diseases of digestive system –II (MBR-I=0.73%, MBR-I=10.70%), other group (MBR-I=0.73%, MBR-II=10.70 %), pyrexia (MBR-I=0.29%, MBR-II= 4.28%), diseases of respiratory system (MBR-I=0.29%, MBR-II=4.28%), lameness (MBR-I=0.22%, MBR-II=3.21%), Mammary gland (MBR-I=0.00%, MBR-II=0.00%). The overall morbidity in adult group was 44.88 percent. Morbidity rates due to diseases of the eye (MBR-I=19.38 %, MBR-II=43.18%) was observed to be maximum, followed by disease of digestive system-I (MBR-I=5.31%, MBR-II=11.84%), surgical problems (MBR-I=4.06%, MBR-II=9.05%), pyrexia (MBR-I=3.63%, MBR-II=8.08%). The effect of sex on overall morbidity rates in suckling group was found to be non-significant and in weaning, hogget and adult group was found to be highly significant (P≤0.01). The effect of year of disease occurrence on overall morbidity in suckling, weaning, hogget and adult group was found to be highly significant (P≤0.01). The effect of season of birth on overall morbidity in suckling, weaning, hogget and adult group was found to be highly significant (P≤0.01). The overall mortality of suckling group was 3.73 per cent. Mortality rates due to diseases of the respiratory system (MTR-I=1.77%, MTR-II=7.29%) was observed to be maximum followed by the diseases of blood (MTR-I=0.85%, MTR-II=3.52%), disease of other group (MTR-I=0.41%, MTR-II=1.69%), diseases of digestive system (MTR-I=0.85%, MTR-II=3.52%), tetanus MTR-I=0.32%, MTR-II=1.30%). The overall mortality of weaner age group was 0.91 percent. Mortality rates due to diseases of the respiratory system (MTR - I =0.47%, MTR-II=3.56%) were observed to be maximum followed by diseases of other group (MTR-I=0.17%, MTR-II=1.27%), reptile bite (MTR-I=0.14 %, MTR-II=1.02%), diseases of blood & digestive system (MTR-I=0.07 %, MTR-II=0.51%). The mortality was 0.66 per cent in hogget group due to all diseases. Mortality rates due to diseases of other group (MTR-I=0.22%, MTR-II=3.21%) was maximum, followed by reptile bite & diseases of respiratory system (MTR-I=0.15%, MTR-II=2.14%), diseases of blood (MTR-I=0.07%, -MTR-II=1.07%), diseases of digestive system & tetanus (MTR-I=0.04%, MTR-II=0.53%). The mortality was 3.94 per cent in adult group due to all diseases. Mortality rates due to diseases of the respiratory system (MTR-I=1.62%, MTR-II=3.62%) was observed to be maximum, followed by diseases of other group (MTR-I=1.00%, MTR-II=2.23%), diseases of blood (MTR-I=0.56%, MTR-II=1.25%), diseases of digestive system & reptile bite (MTR-I=0.38%, MTR-II=0.84%) and tetanus (MTR-I=0.00%, MTR-II=0.00%). The effect of sex on overall mortality in suckling was significant (p≤0.05), weaning and hogget groups were found to be non-significant and in adults were found to be highly significant (p≤0.01). The effect of season of birth on overall mortality in suckling was significant (p≤0.05), weaning and hogget groups were found to be non-significant and in adults were found to be highly significant (p≤0.01). The effect of year of disease on overall mortality in suckling and adult group was highly significant (p≤0.01), weaning and hogget groups were found to be non-significant. The economic losses due to morbidity of various diseases were Rs. 13203.42 (due to body weight of 101.56 kg) for suckling group, Rs. 20180.55 (due to bodyweight of 155.235 kg) for weaning group, Rs. 49568.09 (due to body weight of 381.03 kg) for hogget group, Rs. 120315.26 (due to body weight of 925.50 kg) for adult group. The economic losses on account of wool weight loss were Rs. 497.72 for sickness of 187 lambs in first clip and Rs. 586.46 for sickness of 718 lambs in second clip. The mortality caused economic loss of Rs. 46020.00 due to death of 118 lambs in suckling group, Rs. 54706.6 due to death of 27 lambs in weaning group, Rs. 49023.00 due to death of 18 lambs in hogget group and Rs. 234012.87 due to death of 63 lambs in adult group. The economic losses in terms of wool weight losses due to mortality of all diseases were Rs. 773.40 in first clip and Rs. 3457.64 in second clip. The overall net economic loss on account of body weight loss, wool weight loss and treatment expenditure due to morbidity and mortality of various diseases was Rs. 592345.27 in this flock of Marwari sheep.
