Starting in 2010 , Texas Taurus that undergo a modification of ownership ( except to slaughter ) must be either certified as a virginal Taurus or be tested first for cattle trichomoniasis , a protozoan disease that can make Bos taurus to abort very early on in pregnancy . septic Taurus carry the microscopic organism that cause cattle trichomoniasis without any planetary house and can transmit it to moo-cow during procreation .
“ There is no effective handling for bulls , and once infected , they can retain to spread trichomoniasis when they breed , ” said Dee Ellis , DVM , Texas ’ state veterinarian and head of the Texas Animal Health Commission , the state ’s livestock- and fowl - health regulatory federal agency . “ septic cows may reset the infection , but only if they are give respite from engender for 120 to 150 day — an expensive choice , as a calfskin craw will be missed . A vaccinum also is available to aid in the management of taint cows , but it will not foreclose contagion . ”
Texas ’ ranching , marketing and veterinary industry worked with the TAHC to prepare effective regulations to control cattle trichonomiasis . According to Ellis , more than 600 of Texas ’ veterinary surgeon have been certified to test for the transmission .
Ellis said the new regulations will use to bulls being sold , traded , lease or undergoing any alteration of ownership ( except for slaughter ) in Texas . The regulations include three basic dance step :
2 . licence vestal bulls . A stock breeder can certify the bull as a virgin if the bull was raised away from cow after weaning and is 24 month of long time or jr. . A Texas - origin bull ’s virgin status may be extended to 30 months if the virgin certification is sign up by the breeder ’s accredited veterinarian . Virgin bulls are not required to have a kine trichomoniasis test prior to change of possession .
3 . Test older or non - virgin bulls . Bulls older than 30 months or Samson that were assert with Bos taurus after weaning must have a negative Bos taurus trichomoniasis test within 30 days prior to alteration of ownership . A evidence , accredited veterinary must pull in the sample for essay at the Texas Veterinary Medical Diagnostic Laboratory . While awaiting test upshot , which usually take about a week , the shit must be continue aside from cows . Upon receipt of the negative test results , the bull is ready for modification of ownership .
“ fostering bulls that have n’t been certify as virgins or tested are considered to be debacle - only pig , ” said Dr. Ellis . “ In some cases , however , emptor may want an untested crap , although they may be buying trouble . We have provisions under the regulation for untested bulls to be identified and go under a TAHC - issue hold order and effort permit . The animal must be insulate from female oxen , and can not be moved until it is tested within 30 years of purchase at the possessor ’s disbursal . ”
Texas accept two cattle trichomoniasis test : the real time polymerase chain reaction test or a series of three culture tests . These psychometric test are the national standard . fuzz that examine prescribed may undergo confirmation testing if the owner or accredit veterinarian take a crap a request within five days of the results .
Because there is no effective treatment for oxen trichomoniasis , infected bulls in Texas must go to slaughter within 30 Clarence Day of confirmation . The remaining bulls in a herd will be isolated from distaff cattle until they undergo two consecutive negative RT - PCR test , each deal at least seven mean solar day apart , or three successive negative culture tests , with each of the test conducted at least seven days aside . When they are confirm negative for kine trichomoniasis , the bulls are devoid to be moved or to be commingled with cow .
“ If you are obtaining a upbringing bull , ensure the animal has been demonstrate as a virgin or was test — for your ruck ’s sake , ” Ellis said . “ We will be review the regulations on a yearly basis with an industry working group , to ascertain that the rule remain well-timed and effective . ”
Texas ’ cattle trichomoniasis entry requirements for breeding bull is similar to intrastate rule , but allows out - of - state bulls to be certify as Virgo only until 24 calendar month of years . Exhibition or competition bulls may enter Texas without a trichomoniasis exam , but must be celebrate away from female cattle . The TAHC must be contacted in advance of entry for a release of the trial run requirement to be emerge on exhibition fuzz .
