Total data on body measurement of 539 Marathwadi individuals were collected by taking actual measurements of each individual in 25 villages from five tahsils of Latur district. In order to accomplish the statistical analysis of data the Least Square Technique as outlined by Harvey (1976) was employed. The result obtained from this investigation found that the body measurements in Marthwadi buffalo at 3, 12, 24, 36 months, breeding bulls and more than 36 months females for girth as 75.90 ± 1.13, 95.42 ± 0.82, 126.J 1 ± 2.18, 146.47 ± 1.48, 173.81 ± 1.28 and 169.91 ± 0.72 ems, for body length as 64.29 ± 0.89, 77.47 ± 0.52, 97.05 ± 1.55, 110.45 ± 1.48, 128.70 ± 0.98 and 123.23 ± 0.52 ems and for height as 76.45 ± 0.83, 86.77 ± 0.50, 104.07 ± 1.31, 114.68 ± 0.58, 127.98 ± 0.71and 121.72 ± 0.30 ems, respectively.The body weight in Marathwadi buffalo at 3, 12, 24, 36 months, breeding bulls and more than 36 months females as 34.79 ± 1.44, 67.02 ± 1.61,147.34 ± 7.03 ,221.35 ± 5.62, 360.09 ± 7.53 and 331.63 ± 3.81 kg. In Marathwadi colour pattern recorded as Black and White markings. Black was predominant (95.18 %) followed by White markings (4.82 %). Correlation among the body measurement and body weight in Marathwadi buffalo at different age groups were positive and highly significant among HW and CG, HW and BL, HW and BW, CG and BL, CG and BW and BLand BW. The multiple regression ofbody weight on HW, CG and BL indicated that simultaneous increase by one unit in all three traits, there would be corresponding increase in the body weight by about 1.389 kg (3 m), 2.309 kg (12 m), 3.669 kg (24m), 4.796 kg (36 m), 7.181 kg (Breeding bull) and 6.634 kg (above 36m female buffalo). On the basis of the findings given above it is concluded that in the present study various genotypes of Marathwadi breed included during growth production as well as the factors related to physical development and colour pattern. The study confined to the breeding tract of Marathwadi breed. The geo-ecological situation of the tract and management practices followed plays its role. The size of population studied has indicated valuable parameters to be considered for improvement on field scale. Preferential treatment of males, developmental defects in male and female characters warrant significant attention on both front i.e. care and management and selective breeding in future. Formation of "Breed Society and Registration of Herds" is essential in future. While synthesizing the plan for implementation of various aspects of improvement, should include the further more periodic census of Marathwadi buffalo essentially required so as to know the time trend of Marathwadi population and reasons for the trend. Since in Marathwada region population of two important breeds of buffalo viz., Pandharpuri and Marathwadi are found, the genetic improvement programme should be implemented with proper care. The programme of one breed should not adversely affect the other. Larger population size will be essential aspect of future studies.ennullThesis
