HOW TO RUN A CALIBRATION TEST FOR A BOOM SPRAYER.

The consequences, especially with a herbicide, can be costly. Apply too much and the crop may be damaged or suppressed; apply too little, and weeds may be inadequately controlled.

Using more than is necessary is also a waste of expensive product

When calibrating the boom sprayer , first carry out the necessary calculations and adjustments on a section of road. Next, test the rig on the land; wheel slippage might result in a slightly higher volume than that used on the hard road.

The difference will not be enough to be harmful, but it is worth taking into account – especially as it may vary from land to land, depending on the condition of the soil and whether it is an even, prepared land or has furrows formed into beds.

Follow these steps to carry out calibration accurately and to ensure that the tractor driver follows the correct procedure for spraying:

Step 1
Measure a 100m section of road. Decide on a suitable tractor speed for spraying by selecting the correct gear and engine speed. Use a permanent marker to mark the engine revolutions on the glass of the rev counter. In a suitable spot, mark the gear to be used.

Step 2
Bring the engine up to the correct speed and adjust the spray pressure to get the correct droplet size for the operation. Mark the spot on the gauge where the pressure needle should remain.

With a herbicide, use a flat nozzle and adjust the pressure so that the droplets are the right size: the spray should not be so fine that it drifts away. Getting this right involves both pressure and nozzle size. When checking for drift, look at the spray from the front and the back; it is easier to see the fine droplets from certain positions.

Step 3
Measure the time it takes to drive the tractor for 100m and record this in a suitable place.

Step 4
Place a measuring vessel under a nozzle and let if fill for the time it took the tractor to cover 100m.

Step 5
Multiply this volume by the number of nozzles on the boom to obtain the volume of spray mixture applied over the width of the spray boom every 100m. If the spray boom is 10m wide, you’ll have the amount of mixture applied to 1 000m² (100m x 10m). Multiply this by 10 to obtain the volume in litres applied to 1ha.

Before you spray the land, take the volume of the spray tank and calculate the area that the tank should cover. If you end up covering slightly less area due to the condition of the soil, make the new calculation and adjust the spray accordingly.

Step 6
To double-check, take the measuring vessel and walk behind the boom, collecting spray from a nozzle over the time it takes the tractor to cover 100m. Measure this volume to ensure that it conforms to your calculations.

Step 7
Check that each nozzle sprays correctly and all nozzles deliver the same amount. Inspect for damaged nozzles. Remember that nozzles wear out and deliver more mixture as a result.

Most farmers use the correct product but neglect calibration as it requires extra work. The effort is worth it, believe me!

Seven Surprising Dairy Cow Facts.

Dairy farmers take great pride in caring for their dairy cows and keeping them healthy and comfortable.

Here are seven facts about dairy cows that might surprise you.

Dairy cows have four stomachs. Technically, cows only have one stomach, but it has four distinct compartments. It is very difficult than a human stomach, so that’s why people often say cows have stomachs. The first three compartments process feed in a way that people cannot. Due to this unique digestive system, cows have the ability to convert plants human can’t into nutritious milk.

A cow that is milking eats about 100 pounds of feed each day. The feed is typically a combination of grass, grain and mixture of other ingredients like citrus pulp and cotton seeds. These are items that may otherwise be thrown away. We like to think of cows as the ultimate recyclers. The ingredients that we cannot eat can often be nutritious to them.

A cow that is milking drinks about 30 to 50 gallons of water each day. That’s enough water to fill a bathtub. During periods of heat stress, water intake may double.

There are six main breeds of dairy cows. The main breeds are Ayrshire, brown Swiss, Guernsey, holstein, Jersey, and milking shorthorn. A seventh, red and white, is a variation of the holstein breed.

An average Holstein dairy cow weighs about 1,500 pounds. That’s nearly one tonne. A cows size depends on a variety of factors like age, breed, feeding, genetic potential and other factors.

An average dairy cow produces 7 to 9 gallons of milk a day. That’s about 128 glasses of great tasting, nutrient packed goodness.

Cows like it cool. Due to their thick skin, hair and natural insulation, dairy cows prefer temperatures between 40 and 65 F. Farmers in cooler climates have several ways to take care of their cows in the winter, such as closing the barn doors or hanging plastic curtains over the open sides of the barn. During summer, farmers keep their cows cool by turning on their barns fans and water misters

How to control foot and mouth (FMD) disease in Dairy cattle

Apparently, many livestock keepers have reported the foot and mouth disease in their farms. It true that that the foot and mouth disease is a highly contagious disease, it can spread very fast within and a cross herds or farms. It affects pigs, cattle, and sheep and goat. It is a viral disease that has no cure but one that can be prevented through vaccination.

FMD causes losses in production as it is characteristically causes wounds/blisters on the skin above and between hooves and in the mouth.

Subsequently, the disease makes walking and chewing painful hence the animals does not feed well and if being milked will have a marked reduction in milk yield. Worst still, FMD is a notifiable disease that comes with a quarantine imposition to stem its spread. This of course affects trade in livestock because all markets are normally closed in an area where the disease is reported.

The disease is spread through direct and indirect contact with secretions from infected animals which include milk and semen. The virus can also be spread mechanically through contaminated objects or aerosols or ingestion of contaminated feeds. The virus can also enter the body through broken skin /wound.

During outbreaks there are measures that a farmer can put in place to protect his stock from infection.

1.Fence your farm

A good farm should be fenced, this has positive effect of limiting intruders into the farm. These includes dogs, cats, birds, livestock and people who can easily spread the virus that cause FMD on their feet, clothes, or body and will easily contaminate your farm and thus spread the disease. I don’t mean you fence your farm when you hear FMD is the neighbourhood, a fence should be part of the farm design.

2.Control entry into your farm

A good farm design is crucial in disease prevention. Your dairy unit shouldn’t be the first thing a visitor encounters on entering your farm. It should be positioned in an area that secure and whose access is not for every Tom and Harry.

While you may not prevent people from entering your farm, you can put in place biosecurity measures. This will include a foot bath at the gate for vehicles and people entering your farm. Always keep a visitors book at the gate and ensure it has a column for the origin of the visitors, this will assist in telling whether they are from infected farms.

3.Isolate the sick.

In the unfortunate circumstances that your animals get infected, quickly isolate it from the herd to prevent the spread of the disease. Urgently call your vet to give symptomatic treatment as the disease has no cure but with good timely management the animal can cover.

4.Vaccinate against FMD

FMD vaccines are available in purified oil base form, which protects against all the four strains of FMD virus. The vaccine confers immunity for up to a year after vaccination.

Mobile Milking machines

Role of milking machine in modern dairy agribusiness. 

Milking managements is one of the most important and crucial activities in the milk production chain. The milking machine is unique in the sense that it is one of the few machines which comes in contact with farm animals on regular basis. It is therefore very important that these machines are correctly installed, maintained in excellent operating conditions, and used properly.

Modern milking machines are capable of milking cows quickly and efficiently, without injuring the udder.

The working principle is to imitate the suckling of the calf.

The milking machine performs two basic functions.

  • It opens the streak canal through the use of a partial vacuum, allowing milk to flow out of the teat cistern through a line to a receiving bucket.
  • It massages the teat, which prevents congestion of blood and lymph in the teat.

The milking unit is is the portion which is responsible for removing milk from the cow udder. It is made up of the claw, 4 teat cups, teat shells, teat liners, long tube, long pulsation tube and a pulsator.

Milking machines work in a way that is different from hand milking or calf suckling. Continuous vacuum is applied inside the soft liner to massage milk from the teat by creating pressure difference across the teat canal. Vacuum also help keep the machine attached to the cow.

Milking machines keep the milk enclosed and safe from external contamination. The interior milk contact surfaces of the machine are kept clean by a manual or automated washing procedures implemented after milking is completed. Milk contact surfaces of the machine must comply with regulations requiring food-grade materials and are easily cleaned.

Most milking machines are powered by electricity but, in case of electrical failure, there can be an alternative means of motive power like a generator.
