The Bob Veal Calf Concern

The Bob Veal Calf Concern

Bull calves in the dairy business are most often a topic that producers would rather not think about. The financial returns from selling them are usually low. There are unavoidable labor costs in their care. The sooner they leave the farm the better is the usual mantra. Too many of these critters become bob veal - early slaughtered calves with minimal economic value. Farmers are reluctant to put more time and effort into insuring a strong and healthy calf that has a good chance of entering a veal raising operation. This means holding on to these calves for some extra days risking the chance of scours or worse yet death. Veal managers do not want light, less vigorous and very young bull calves for fear of high loss rates as well. Experience tells them that larger and more active calves will do better and result in lower mortality rates and better feed conversion.

There has been another issue creeping onto the scene, that of antibiotic residues in bob veal. Few people are bold enough to think that treating a young calf directly with injectable antibiotics will not result in detectable tissue levels if that animal enters the food chain within a few days. The problem is generally not from injectable products, but from oral scour medications, medicated milk replacers and more rarely colostrum containing antibiotics. Neomycin has been the most common culprit.

Neomycin and tetracycline have both been included in some scour medications and milk replacers for many years. Labeling of these scour treatments can be misleading as to withdrawal times. Medicated milk replacers do not contain treatment levels of these antibiotics, but are formulated for use in heifer calves not calves destined for bob veal. Colostrum from cows treated with oil based dry treatments is most likely to carry residues of significance to the newborn calf. Dry treating less than the labeled days pre-calving, double tubing or treating a slack quarter can result in higher than expected first milking antibiotic levels.
Holding out milk on fresh cows according to the labeled recommendations on dry treatment and not feeding it to bull calves is an extra measure of safety. The vast majority of colostrum will not cause an issue, however. Feeding heifer colostrum to bull calves is a failsafe way of preventing colostrum based problems provided that the practice of dry treating springers is not in place.

Weed Resistance Management Demonstration and Plot Tour

Event Offers DEC Credits

July 23, 2019
1:00 - 3:00 p.m.
Waterloo, NY

Come join us on July 23 in Seneca County at Quinten Good's farm for a demonstration and walking tour of 16 different pre- and post-emergence treatments in soybean and 12 different treatments and combinations in corn.
  • Tall waterhemp and marestail are two weeds that are resistant to glyphosate and ALS herbicide modes of action in the WNY and Finger Lakes regions.
  • Each year the number of acres with resistant weed populations expands.
  • For herbicides to be an effective tool in weed management, we have to know what chemistries & application timings are most effective against these resistant weeds.

RMA Announces Additional One-time Changes to Prevented Planting Provisions

June 29, 2019

RMA Announces Additional One-time Changes to Prevented Planting Provisions
for 2019 Crop Year

In response to delayed and prevented planting resulting from above average rainfall and wetness, the USDA Risk Management Agency has made a one-time change to the 2019 crop year prevented planting rules that effectively allows silage corn, if planted as a cover crop following local agricultural expert guidelines, to be acceptable as a post-prevented planting cover crop. Under this one-time rule change, producers are allowed to produce this crop while retaining their prevented planting payment. This change couples with previously announced one-time changes to the prevented planting rules - including expanded acceptable uses for post-prevented planting cover crops and a change in the cover crop haying and grazing start date rule - serve to help those struggling to meet their forage needs due to the weather.

Read the full article from the New York Crop Insurance Education Program.

The USDA-RMA states that "For crop insurance purposes, a cover crop is a crop generally recognized by agricultural experts as agronomically sound for the area for erosion control or other purposes related to conservation or soil improvement." PRO-DAIRY specialists Joe Lawrence and Karl Czymmek and Dr. Quirine Ketterings, Professor and Director of Cornell Nutrient Management Spear Program have released a letter stating "Corn on Prevented Planting acres meets these objectives."


New Guidance for Mortality Disposal Issued

NYS Department of Ag and Markets has posted guidelines on disposal of livestock carcasses, in response to reports that some rendering companies have halted pickups from farms.
