Grazette Newsletter - April 2012

Web image: Grazing Lands Conservation Initiative - April 2012 Newsletter

April  2012 Edition

Last month we noted that March usually “comes in like a lion and goes out like a lamb”, and that it would be interesting to see if the weather pattern changed. When May-like weather shows up in the middle of March, and trees start to bud and grass begins to grow, that is a change! However, the question was if it would change to more winter-like conditions, which we did not see. There are some farms that have already turned animals out on pasture, although it’s probably not a major portion of their diet yet. If you have turned out, or are considering it, please read the pasture management tips below for some precautionary information.

New! We've added some of our past newsletters at the end of this page.

Please continue to send in notices of pasture walks and workshops by three days prior to the end of each month. The Grazette is distributed monthly.

Jefferson/Lewis County Grazer’s Discussion Group

When: Wednesday, April 18th - 11:00AM to 2:00PM
Where: Grace Episcopal Church, Copenhagen

This and all get-togethers are open to any dairy grazers. At least three pasture walks and discussion are planned throughout the spring, summer and fall in Jefferson and Lewis Counties. We ask you to bring your topics for discussion and locations for walks to this meeting. Discussion on identified items we would like to focus on throughout the grazing season include developing a pasture plan and running the farm through Soil and Water Conservation District Agricultural Environmental Management (AEM) worksheets, using pasture measurement to improve management and the rising plate meter to estimate pounds of dry matter, and the Dairy Profit Monitor and calculating net milk income over feed costs per cow, tracking performance of pasture program and utilizing it to improve the quality of pasture management decisions.

Other areas of interest include: Alternative crops to graze; Seasonal grazing; Genetics and crossbreeding; Recover overgrown/forested pastures; Facilities/laneways; Fly control. The group will be facilitated by Ron Kuck, Cornell cooperative Extension (CCE), Jefferson County and Levi Rudd, Jefferson County SWCD. There is no fee for this meeting and lunch will be provided, the only thing that is asked is that you call in with reservations to make sure we have enough seating by April 16, 2012. Please direct all calls to Ron Kuck 315-788-8450 or Ron's email. This discussion group is sponsored by the following groups: Pro-Dairy-Cornell University, Jefferson and Lewis County Soil and Water Conservation District, Jefferson and Lewis County Cooperative Extension, and Adirondack North Country Association (ANCA).

Pasture Management Tips

Spring Time Can Be a Hazardous Time for Your Grazing Livestock

This year spring has been unusually warm and many plants are already starting to grow. The weather can turn cold again though, and the risk of frost is still a concern. This is a particular concern when trees and shrubs start to grow leaves and then a heavy frost causes them to wilt. Livestock producers need to be cautious of this when livestock are first starting to graze pastures that have trees along the edges or inside the pastures. The most common trees of concern are; Maples, All Cherry species, Black locust and Oak trees. The following is a list of toxins contained in each tree species.

Maple trees (Acer rubrum)
The toxin in Maples is Gallic acid, this causes acute hemolysis (hemolytic anemia). Evidence suggests that this acid is responsible for the Red Blood Cell (RBC) lysis, which is the red blood cells splitting, releasing the hemoglobin not allowing the animals blood to clot. The toxicity results from the ingestion of fresh, wilted and dried leaves are toxic and ingestion of as little as 0.3 percent of the body weight as leaves is toxic to horses.

Black Cherry (Prunus serotina)
The toxin in Black Cherry is prussic acid, a form of cyanide. Anxiety, difficult breathing, staggering, convulsions, collapse and death may be sudden. The toxicity results from damaged or wilted leaves pose the greatest risk; all parts are potentially toxic.

Black Locust (Robinia pseudo –acaia)
The toxins in Black Locust are the protein robin, the glycoside robitin and the alkaloid robinine. These toxins affect the gastrointestinal tract as well as the nervous system. Depression, poor appetite, weakness, paralysis, abdominal pain, diarrhea and abnormal heartbeat cause by his toxin. Death is possible. The toxicity results from ingestion of leaves, especially wilted leaves, young shoots, pods, seeds and inner bark.

Oaks (Quercus spp)
The toxins in Oak are called gallotoxins. They are converted in the body to tannic acid, gallic acid and pyrogallol, all of which are very toxic to the kidney. Lesions include peri-renal edema, nephrosis, gastroenteritis, anorexia, rumen stasis, constipation, followed by dark tarry diarrhea, dry muzzle, frequent urination, rapid weak pulse. Death can result from ingestion of this species of tree. The leaves when young or wilted and swollen or sprouting acorns are the parts of the plant that are most toxic. Oak is most dangerous early in the spring when the leaves and buds are the highest in toxicity and there is little else to eat. Autumn is another at-risk period, when acorns and leaves fall and better forage dies.

Livestock should avoid grazing pastures with these tree species during the early spring and again in late fall when there is a chance of the leaves wilting due to frost.

Sheep and Goat Parasite Warning

In a study with goat farmers in New York and Pennsylvania in 2008, it appeared that barber pole worm larvae that “hibernate” inside sheep and goats over the winter stop “hibernating” by early March and turn into adults laying viable eggs. Luckily for us in most years the ground is still pretty cold in March and we do not get much hatching of these eggs because they need temperatures of 50 degrees Fahrenheit and up to start to hatch and can’t survive extremely cold temperatures. However, when temperatures get into the upper 70’s you get lots of hatching within three to five days.

Unfortunately, this year has not been real normal and your winter barnyards and pastures may be far more worm infected than normal. Given the weather the last couple of weeks we probably have far more infectious barber pole worm larva in our winter pastures and barnyards then we do in normal years. Keep in mind that most of our other stomach and intestinal worms of sheep and goats overwinter outside fairly successfully unless the wind chills have been subzero for an extended period of time with little or no snow cover. Although most of us have not had a lot of snow this year we sure have not had much in the way of subzero wind chills.

Assuming that your winter barnyards are relatively free of worms is probably not a good assumption right now. You may want to move them out of these areas if enough grass is showing up in them that your animals are starting to graze in them. Keep an eye on the FAMACHA scores of your sheep and goats and on their body condition if you still have them out on your winter areas and plan to rest those winter paddocks and pastures for quite a while before you graze them this growing season. Talk with your vets and extension educators about your parasite control plan for this year. Remember late pregnancy and lactating females and their growing offspring will be most susceptible.
