How can I treat frothy bloat in my cow?: Click here

Answer: Frothy bloat refers to a condition when a ruminant consumes forages that produce a frothy gas in the rumen and the animal cannot pass the gas. The rumen gets so full of gas that it eventually presses against the heart or lungs and the animal expires. Legumes such as alfalfa and clovers can cause bloat. In Montana, for example, alfalfa hay from first and second cuttings will generally not bloat cows, but alfalfa hay from third cutting can. Clovers and alfalfa in pastures can also bloat cows. Birdsfoot Trefoil and Sanfoin are legumes containing tannins that do not let the frothy gases form, hence no bloat.

Whenever you look at a cow, always critically evaluate five areas: eyes, ears, rumen, udder, and manure. After a while, this will become second nature to you. The rumen "triangle," or paralumbar fossa (see www.merckmanuals.com/media/vet/figures/DIG_cannulation_of_rumen_cow.gif for a useful graphic) should be not be expanded; if it is, the animal is going to bloat or already bloating. The following link shows what a cow looks like when she is bloating: www.ianrpubs.unl.edu/epublic/live/g2018/build/graphics/g2018-1.jpg.

The paralumbar fossa is also known as the "death triangle." Besides checking for bloat, it is an easy way to check if a cow's feed intake is normal. If you see a severely "dished in" triangle, the cow’s feed is incorrect—either you are under-feeding her or she is off her feed for some reason.

To treat bloat, use Therabloat from your vet. It comes in a two-ounce vial. Pour the vial into a 16-ounce soda bottle, add about 10 ounces of water, and drench the cow with it. If you have not drenched a cow before, it is probably best to call your veterinarian for assistance, as it is possible to get the fluid into her lungs by mistake. It does not hurt to keep the cow walking for 30 minutes. About 10 minutes after administering the drench, the cow will start to belch. Generally, in one hour, the bloat is relieved. This treatment must be administered before the cow is down. When she is in a prostrate position, your chances of saving her are reduced. It is not a bad idea to have vial or two of Therabloat on hand at all times.

Inserting a needle, knife, or trocar into the rumen via the paralumbar fossa is not recommended to treat bloat. While effective in relieving the bloat condition, this procedure also almost always causes peritonitis, which is an intense systemic infection that is often untreatable. Peritonitis will kill the cow in about three to five days.

To prevent bloat, you can feed a bloat block that the cow can lick on. It is a molasses base, so intake is generally assured. The key to prevention is also to always keep feed in front of the cow—keep her full.

What are some options to organically deworm my cow and her calf?: Click here

Answer: There are several things you can do to reduce the need for deworming. Providing your cows with excellent nutrition, practicing rotational grazing, and breeding for parasite resistance can reduce your dependence on deworming medications. All animals will face some parasite burden. Your goal should be to deworm only animals that actually need treatment— that is, animals that are showing signs of parasitism.

There are several natural compounds that have been used to organically treat cattle, including garlic, tannin containing plants like Sericea lespedeza, copper boluses, chicory, and wormwood.

If you are certified organic, then you must check with your certifier before treating your animals. You must ensure you are treating with an approved substance. You should also check with your local veterinarian. He or she can perform a fecal egg count on your animals, letting you know the parasite load and what types of parasites your animals have. You may find out that your animals aren't actually in need of treatment.

If your cow is on pasture, incorporating a three-pronged approach into your grazing strategy will reduce worm infestation.

A common cattle parasite, the Brown Stomach Worm (Ostertagia ostertagi), will locate two to three inches up the grass stem within six days of exiting the manure pat. Dividing your pastures into paddocks and exiting the paddocks with a five- to six-inch residual height of grass will greatly reduce the ingestion of infective larvae. Additionally, moving cattle to a new paddock at least every five days significantly decreases the chance of infection. Furthermore, instituting a pasture rest of greater than 35 days will decrease the survival of the infective larvae. To accomplish this, you will need to divide your pasture into at least eight five-day paddocks. In areas of rainfall pasture, more paddocks will have to be added during the drier parts of the summer when the grass growth is slower in order to maintain your 35-day pasture rest.

In contrast, continuous grazing ignores all three of these management controls. Consequently, cattle are subjected to the parasite levels that can easily overcome the animals' ability to resist infection.

What can you tell me about flame weeding as a method of weed control in organic crops?: Click here

Answer: Flame weeding is a non-chemical weed-control technique common among organic farmers. Flame weeding, also referred to as flame cultivation, often uses propane gas burners to produce a carefully controlled flame that briefly passes over weeds. The intense heat blanches the leaves, causing a disruption within the plant’s cell walls. Flamed weeds usually wilt and die anywhere from within a few minutes to a few days after flaming. One quick way to check to see if the plant foliage has been adequately flamed is to see if a thumb print is retained on the leaf when pressed between your thumb and finger.

Weeds are most susceptible to flaming when they are one- to two-inch-tall seedlings. Broadleaf weeds are more susceptible to flaming than grasses as grasses develop a protective sheath by the time they are approximately one inch tall. Therefore, grasses may require a second flaming. Repeated flaming can also be used to suppress perennial weeds such as field bindweed. Flame weeding is commonly used in the stale seedbed method, which involves allowing weeds to grow in order to be killed by the flame (or other method). This method is usually repeated prior to planting a cash crop as another flaming may be used after planting and before germination of the cash crop.

Flaming on dry, sunny days is recommended as any moisture can give the plants some resistance to the heat. For larger areas, working in sections can help establish effective fire breaks, particularly when flaming dried material, such as stubble, as it can ignite. Green plants usually do not ignite when treated with a flame.

Most flame weeders are designed to not radiate large amounts of heat. Their purpose is to sear the leaves of plants (weeds) in order to change the protein structure of the plants. As a result, stress kills the weeds, not the torching of them. Due to the design and purpose of flame weeders, there is no soil disturbance and generally not enough heat is produced to penetrate the soil and effect soil life. As stated above, timing is everything.

There are several different designs commercially available for tractor-mounted flame weeders. Some flame weeders burn propane in the gas state, while others burn gas in the liquid state. It is important to note that tractor-mounted tanks should be rated for “motor fuel” as they will be mobile and not stationary. Another design difference is whether the gas flows directly from the tank to the burners, or is distributed through a manifold first. In addition, the burners may be fixed or adjustable, with the latter offering the ability to adjust the position of the flame. Having individual shut-off valves for each burner provides flexibility in using a flame weeder so that the flames can be directed or broadcast over an area. Flame weeders are available with different BTU (British Thermal Unit) ratings.

In addition to weed-control benefits, flame weeders can also be utilized for other applications. According to some resources, potato plants up to eight inches tall can be flamed to kill Colorado Potato Beetles, Leptinotarsa decemlineata, without causing undue damage to the potato plants. Flamers can also be used to incinerate fallen fruit and mulch.
