Habitat analysis, include biophysics environmental conditions of swamp buffalo (Bubalus bubalis) has been conducted in June until December 2017 in Rambutan (Banyuasin) and Ogan Ilir (Indralaya) district, South Sumatra and the laboratory of Animal Physiology, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Sriwijaya, Indralaya. The purpose of research is to know swamp buffalo habitat characteristics at the district of Rambutan (Banyuasin) and Indralaya (Ogan Ilir) by physical, chemical, soil and vegetation conditions in the habitat of buffalo. The sampling method of buffalo was used purposive sampling method wheareas vegetation sampling using the quadrant method or plot. Data analysis techniques used are in qualitative and quantitative. The data is then presented in the form of tables and diagrams and narratives to interpret the data. Based on identification and field observations of vegetation conditions, Rambutan vegetation was consist of 15 species and Indralaya vegetation was consist of 9 species for swamp buffalo food. Temperature inside and outside of cage in Indralaya is 22.3 to 31.3 deg C while temperature in Rambutan is 23.2 to 32.8 deg C. Potential of hydrogen soil is 5.10 to 5.60 and always inundated by water. It can be concluded that the form of lowland biophysics environmental. Conditions of swamp buffalo dominated by grasses belonging to the family of Cyperaceae, Graminae, Fabaceae and Poaceae as the main source of food, while the state of the temperature is very supportive for buffalo habitat.

Udder length, width and height are very important parameters to identify good dairy animals. Udder measurements including length, width and height on 437 Nili Ravi buffaloes were recorded before and after miking with 1180 records at 6 Experimental Stations in Punjab, Pakistan. Heritabilities were estimated using Best Linear Unbiased Prediction techniques. Environmental factors viz age of the buffalo at scoring, stage of lactation, parity, herd and season were included in the model. Least square means for udder length, width and height before milking were found as 52.65+-6.87, 53.52+-6.19 and 54.34+-4.99 cm and after milking as 47.08+-6.57, 48.15+-5.79 and 55.39+-5.15 cm, respectively. Heritability estimates for udder length, width and height before milking were found as 0.08+-0.07, 0.22+-0.08 and 0.22+-0.09, while after milking as 0.14+-0.07, 0.20+-0.08 and 0.09+-0.08, respectively. All the factors significantly affected before milking udder length. A significant effect of herd, parity, season of scoring and age on udder width before milking was observed. Herd, stage of lactation, parity and age of the buffalo at scoring significantly affected udder height before milking. Significant effect of herd, parity, stage of lactation and age of the buffaloes at classification on most of the traits suggest that managemental factors are important. Moderate heritability estimates for these udder traits provide a fair scope for improvement through selection and breeding which will help to increase milk yield in Nili Ravi buffaloes.
