چکیده
Dairy cattle raising has been developing rapidly although there were some troubles. Total dairy herd was more than 110,000 heads in the whole country, of which there were 59,958 heads in Ho Chi Minh City (June, 2006). It exceeded the Governmental plan for dairy development. However, some provinces could not keep their dairy development program continuously. They had invested on many aspects concerning with dairy production, but their dairy herd has still dropped considerably. Dairy cattle can not give a normal production and reproduction under environmental, management conditions in these regions. Some reproductive diseases, such as: anestrus, repeat-breeding, retained-placenta, metritis... have been considered the main reasons of reproduction failure of dairy cattle. Relating to the less milk production, sub-clinical mastitis has been considered a major constraint by some previous surveys. However, these factors have not yet studied detaily and their economical loss have not yet evaluated concretely. So, the project aims at:

Oxidative stress, induced by reactive oxygen species (ROS), is believed to be aprimary factor in various cattle diseases including mastitis, but there are few studies regarding the role ofROS in subclinical mastitis. This study was undertaken to i) study the changes...

متن کاملA polymerase chain reaction based study on the subclinical mastitis caused by Streptococcus agalactiae, S. dysgalactiae and S. uberis in cattle in Ahvaz
Streptococcus agalactiae , S. dysgalactiae and S. uberis are Gram-positive bacterial pathogens that affect cows in dairy herds. These are considered as the major causes of economic losses of dairy producers without a control program. To reveal the role of these agents in inducing subclinical mastitis in dairy cattle in Ahvaz, 100 CMT-positive milk samples and 20 CMT-negative milk samples were c...

Mastitis is one of the most serious and costly diseases affecting dairy cattle production. In the present study, effects of a lactoferrin gene polymorphism (intron 6) on milk somatic cell count (SCC) and subclinical mastitis was investigated in 121 Holstein dairy cattle. Two alleles of A and B and two genotypes of AA and AB were found in an EcoRI recognized single nucleotide polymorphism in int...
