In this paper, the development history of the world's buffalo survey, this paper discusses the development history of the world's buffalo and current status, from the present situation of the development of the world's buffalo in China buffalo industry trends, according to the National Buffalo trends, focuses on the Fuan-the characteristics of buffalo for the future development of Fu'an buffalo, provides a theoretical basis for the effective and targeted Fuan, improve on the views of the characteristics of buffalo, in order to provide first-hand information for improving the work of Fu'an buffalo hybrids.This article through field surveys and field measurements to obtaine Fu buffalo chest development (chest index for the 150-157%), bone-shaped thick (Tube Circuit index 17-19%), body height almost equal to body length (body length index for the 104-107%). Fuan buffalo herds number is 1858, Fuan buffalo herd structure are better than before in the old, weak, sick, disabled reduction in the number of buffalo, increase in young adults, the group tends to be more young, robust body condition. Fuan Buffalo Bulls, the average ante-mortem weight are 406.1kg, cows are 377.3kg; bull slaughter rate, net meat rates are 50.7% and 39.8%, cow are 50.0% and 41.3%, Steer are 61.5% and 35.2%;respectively. bull's bone to meat ratio is 4.94, cow is 5.29; Bulls area rib eye is 54.13cm2, cow is 49.18cm2.This paper also conducted a survey to Fuan buffalo breeding, through the investigation we knowed the life cycle of Fuan buffalo was 14-year-old, breeding age usually 7 years or so, if feeding and management good, light labor, reproductive life up to 10 years old. Usually around the age of 4-7 for the breeding peak, the age of eight and then gradually decreased. Investigation 32 Fuan reproductive performance of buffalo, Fu'an buffalo initial distribution period is 30.25±3.61 (18-35), the early production period was 40.84±3.53 (29-46), calving interval was 390.63±46.59 (290-480) Fuan buffalo initial distribution phase and the beginning of birth is also slightly earlier than the Murrah buffalo, calving interval slightly longer than the Murrah buffalo, Fuan buffalo reproductive performance was good, but the main problem is Fuan buffalo cow mixed group of public grazing, wild cross easily lead to chaos with a close relative with early.This paper for the first time in nine Fuan buffalo blood physiological and biochemical indicators measured the average number of red blood cells Fu'an buffaloes was 5.35±4.02×1012/L, average number of red blood cells was 5.04±4.02×1012/L, the total number of white blood was 11.42±3.98×109/L, the total protein content was 69.75±5.92g/ L.In this paper, Fuan buffalo milk Characteristics were measured with the performance, study and put forward for the buffalo of the lactation characteristics of the method for improving lactation. The lactation from this survey, the Fuan buffalo lactation period is usually 5 to 10 months, an average of 226 days, a minimum of 151 days, the longest was 302 days. Lactation period of lactation in a volume of 372~632kg, the average lactation period of lactation of 527.2kg, the daily average volume of lactation 2.34kg; and the determination of 150-300 days in 1980, with an average lactation period of 210 days compared to lactation a long period of 16 days; lactation has been lower than growth in 1980, but the increment is not obvious.
