Abstract

Firstly, a survey of the history of the development of the world buffalo, discusses the history and current status of the development of the world buffalo, the development trend of the to see buffalo industry in China from the current development of the global water buffalo, according to the trends buffalo the country, focused on the buffalo Fuan dairy characteristics of effective theoretical basis for the future development of Fuan buffalo and improved views for the Fuan buffalo characteristics, the Crossbreeding work Fuan buffalo to provide first-hand information. This article by field surveys and field measurements derived the Fuan buffalo chest development (Bust index 150-157%), boned (width index 17-19%), body height almost equal to body length (body length Index for 104-107 %). The number of the Fuan buffalo herds 1858, Fuan buffalo herd structure than before the old, weak, sick, disabled and reduce the number of young buffalo increased, the groups tend to be more young, body condition robust. The Fuan buffalo bull the average before slaughter weight of 406.1kg, the cow 377.3kg; the bull slaughter rates, lean percentage was 50.7% and 39.8%, respectively, the cows for 50.0% and 41.3%, 61.5% and 35.2% steers ; flesh and blood of the bull ratio is 4.94, and the cow was 5.29; bull's eye muscle area 54.13cm2 cows 49.18cm2. The Fuan buffalo breeding, through the investigation shows Fuan buffalo life cycle in the 14-year-old breeding life of general for about seven years, good feeding and management, servitude light, breeding life of up to 10 years old. The breeding season usually about 4-7 years, 8 years old and then gradually decreased. Investigation of 32 the Fuan buffalo breeding performance, Fu'an buffalo with the early period was 30.25 ± 3.61 months (18-35 months), early production period is 40.84 ± 3.53 months (29-46 months), calving interval was 390.63 ± 46.59 days (290-480 days), the Fuan buffalo with the early period and early production phase Bi Mola buffalo also a little earlier, the calving interval Murrah buffalo close, say the Mingfu An buffalo breeding better performance, but Fuan buffalo breeding The problem is a mixed group of male cows grazing, wild cross chaos with easily lead to the next of kin as early as equipped. This article was first Fuan buffalo nine blood physiological and biochemical parameters were measured, the Fuan buffalo average of the number of red blood cells to 5.35 ± 4.02 × 1012 / L, the Fuan buffalo mother buffalo average of the number of red blood cells 5.04 ± 4.02 × 1012 / L; the total number of white blood cells to 10.56 ± 3.49 × 109 / L;, the total number of white blood cells to 11.42 ± 3.98 × 109 / L, the Fuan buffalo total protein content of 69.75 ± 5.92 g / L The Fuan buffalo and mother buffalo the physiological and biochemical indicators are very similar, the difference was not significant (P lt; 0.05) by t test. This suggests that the physiological and biochemical indices of Fu'an buffalo there is no significant difference in gender, both male buffalo and mother buffalo overall indicators can be used as judgment Fuan buffalo health standard. Fuan buffalo milk with performance measurement, research, methods to increase milk yield and lactation characteristics for buffalo. From the lactation survey, the Fuan buffalo lactation period is usually 5-10 months, an average of 226 days, a minimum of 151 days, the longest of 302 days. Milk yield in a lactation period of 372-632kg, average lactation milk yield of 527.2kg, the average daily milk yield of 2.34kg; compared with the determination of 150-300 days in 1980, an average of 210 days of lactation, lactation a long period of sixteen days; milk yield increase compared to 1980, but increased the amount is not obvious. 65 buffalo on the Fuan buffalo germplasm resources protection field the Fasciola hepatica census, and analyze the results of the census. 65 buffalo in the Fuan buffalo species resources protection field survey, stool examination revealed 15 water cow dung samples Fasciola hepatica eggs, the positive rate was 23.08%. The infected buffalo minimum age of 10 months, with a maximum of 6 years, the positive rate increased with increasing age. The cow positive rate of 13.61%, bulls positive rate of 16.74%. The infected buffalo EPG 5-40 gold.
