A2O-Lancaster Farmina. Saturday. Auaust 16. 2003 Penn State Cooperative Extension Capitol Region Dairy Team COULD LEPTO BE CAUSING YOUR BREEDING PROBLEMS? Dr. Arlen Mills Capital Region Extension Veterinarian Lebanon About all farms I visit vacci nate for lepto on a regular basis. But in spite of a regular vaccina tion, lepto can still be a problem. Most vaccines used contain five different strains of the lepto organism. One of these types or strains has been known as lepto hardjo. It has been known for years that cattle are the normal host of this type of lepto and can carry the organism and shed it into the environment around them. Our current vaccines have not been shown to be effective in the control of lepto hardjo. The lepto hardjo strain has re cently been better defined and re named as Leptospira borbpeter senii serovar hardjo (type hardjo bovis). Lepto infections have been shown to cause chronic reproduc tive problems in infected herds. This can be seen as early em bryonic death, resulting in an in crease in services per conception. Infected cows may be bred and may miss a heat only to be seen in heat later. It may also cause an occasional abortion and the birth of weak calves that usually do not survive. Also linked to lepto hardjo bovis infections is a type of masti Where simple goodness begins.™ Stop by our booth in the Dairy & Livestock Tent at Ag Progress Days.

These cows will eventually start eating but rarely return to normal milk production. If any of these symptoms are seen in a herd, diagnosis has been a problem. Cattle do not develop a good immune response to lepto infection. Even taking two blood samples three to four weeks apart has not been helpful as it often is for other infectious organisms. Researchers at Michigan State University have determined a method to collect urine from sus pect cows and check for the lepto organism. The urine must be col lected after giving cows Lasix to dilute the urine to flush the or ganism from the cow’s kidneys. Herds where lepto is suspected as causing reproductive problems need to consider collecting urine on several cows to submit for testing. This can be done along with blood tests to check for BVD and Neospora. Lepto vaccines currently avail able may not protect against the lepto hardjo-bovis strain. We know that vaccination does not prevent infected cows from shed ding the organism in urine and uterine secretions. So current vaccination use may only give us a false sense of security.

Fortunately, a new vaccine will soon be available that will protect against lepto hardjo-bovis infec tion.

The information found in Pennsylvania Horse Power is a summary of the results found in the “2002 Pennsylvania Equine Survey” in addition to other spe cific facts noted. The “2002 Pennsylvania Equine Survey” was conducted the Pennsylvania State Universi ty. The Pennsylvania Department of Agriculture, through the State Horse and Harness Racing Com missions, contracted with The Pennsylvania State University to conduct the study. Look for the second half of this summary in an upcoming issue of Lancaster Farming. STATE COLLEGE (Centre Co.) Horses are a huge force in Pennsylvania’s culture and economy. Just as horses were im portant enough to our forefathers to include on Pennsylvania’s State Seal, this study suggests that the state’s thriving equine in dustry can help enhance the quality of life for future generations. This study shows that the number of equine has increased 27 percent in the last ten years. More horses mean a stronger demand for production agriculture and the infrastructure that supports it. Most Pennsyl vanians agree that more farmland and a strong farm economy are good for ' *! ' ♦ Mi! K Dr. Ann ML Swinker Extension Horse Specialist Penn State fected. The initial vaccine will apparently contain only the new strain and will have to be used in addition to the available five strain lepto vaccine. If you are having trouble get Equine Survey Summarized everyone’s quality of life, Economic Value Overall, the direct and second ary contributions of the state’s equine industry are estimated at more than $1.12 billion in reve nue (output), of which nearly $615 million is value-added. This translates into 20,300 jobs that compensate state workers with $412.2 million. The racehorse survey indicated that this portion of the industry generated $197.4 million in out put and $100.6 million in value added. This activity directly sup ported 4,740 jobs. Accounting for multiplier effects, the racing in dustry supported an additional $147.1 million in output, of which $B7 million was value added, and 1,690 additional jobs. The general population results indicated that the industry di rectly generates $445.5 million in output, of which $229.9 million is value added. This activity pro vides 10,220 jobs. And the ripple effects generate still more eco nomic activity, supporting $334.5 million in output, of which $197.6 million is value-added, and 3,650 additional jobs.
