Feeding and Watering Adjustment for Success

You are What You Eat

With the rising heat and feed costs we look at every way to help conserve feed.  Feed and water waste should be avoided as any spilled feed is an open invitation to pests coming in for a meal.  Darkling beetles and other pests feed off of spilled feed and water spots in bedding before breeding and destroying a wooden structure.

The birds we use for food do not have valves in their esophagus as humans, so they need to tip up their heads as they drink and eat.  Positioning feeder and drinker levels to be at or just above where the neck meets the body is a preferred feeding method.  Be sure that bell-type drinkers are adequately weighted in their ballasts to prevent spillage.  Use a waterer location rotation program with these hanging drinkers to help eliminate wet spots in the litter.

 Nipple drinkers should be positioned and adjusted so that birds can reach up to drink.  By doing so, the birds can drink naturally with the water flowing down their throats and without the need for moving with their mouths full of water.  Leveling the system as you move through the house is important to help eliminate and air blockages and "weeping" drinkers.

Fount type drinkers that sit on the floor can be raised using blocks and other supports to help raise the equipment to the proper feeding level.  Having the equipment adjusted as the bird ages ensures that feed and water are properly being delivered.

Heat stress - Putting Ventilation to the TEST

Keeping Cool Takes Work 

When we consider cooling birds, most producers first turn to a fan for help.  Fans do a great job of reducing temperature of a poultry house by using convection to help remove heat that is surrounding the bird.  Birds use the evaporation of water from their respiratory system to help cool their bodies.  Larger comb varieties also cool themselves by circulating blood through their comb and wattles.  Testing the air by using a hygrometer to test temperature depression using ventilation is a simple method to determine the possible effectiveness of using fans.

Two things a caretaker should concern themselves during hot weather.  Keeping the fans running efficiently, and running them long enough to help the birds cool properly.

Proper fan maintenance, includes brushing off shutters and doors to keep them free of any dirt and debris.  This also includes the brushing off of fan blades so that they will "Bite" the air properly to move air through the fan.  Do not attempt to brush off a fan without stopping electrical power to the unit.  Do not forget to brush off the motor, as even sealed motors can cool better when not covered in dust!  While brushing off fans, check belts and pulleys for wear and replace these as soon as possible.  Worn pulleys will actually slow down a fan reducing the volume of air that can be moved.

Lastly, fans should run long enough to bring house temps down long enough for the birds to rest from heat stress.  Consider overshooting house temp by allowing a house to cool to 70 degrees long enough for birds to eat and digest their food.  If done during the cool part of the day, egg production and growth in meat birds should continue even on the weeks of high daily temperatures.

Pastured Poultry & Rotational Grazing

Pasture Quality & Condition is Important 

I had the chance to visit several pastured poultry farms this week and I was reminded of how this was done in the early 1920's.  Birds were routinely pastured to take advantage of sunlight (vit. D) and the natural grasses they ate.  What is so different between operations of today and yesteryear is that we tend to restrict our birds in one area as we graze.  This creates a host of problems as the grass becomes over-run by the birds and heavy loads of manure accumulate.

Rotational grazing should be just that.  Moving the birds frequently to keep grass in good condition and to help spread out manure loads in a field being grazed.  You should move birds before all the grasses they are bedding on become stomped down.  Supplemental feeding is also important at this time to make sure the birds are receiving all essential nutrients that they are not getting from the grasses they are feeding on.  Clover for example has a high protein content than most grass species.  Therefore the corn in a full feed poultry diet will help compensate and provide the energy component of the birds daily nutritional needs.

By rotation of the pasture, the sun can help sanitize the ground last occupied by the birds.  With frequent rotation, the pastures can recover more quickly and in turn provide more forage opportunities for the birds.  Your pasture after the move of the birds will tell how well you are doing on your pasture management program.

Foot Health in Poultry

Putting your best foot forward                              

Like all farm animals being able to move is very important.  Over the years, foot health has gained interest in meat birds and breeding stock, since if a bird can't walk it can't eat and a dangerous spiral starts if not corrected.

It is important to note that moisture plays a large part in a bird's foot health.  Litter and floor conditions that are too wet begin to erode the skin on the foot pad and can lead to inflammation (bumblefoot) and lameness.  Moisture created by the birds along with water spillage if not managed can create lameness in a flock.  You can test litter moisture by picking up a large handful of litter and squeezing it.  Excessively wet litter will ball up or drip water, and feel sticky to touch.  Add additional litter if possible or stir existing litter to help promote drying.  Adjust ventilation rates to help remove moisture from the house and keep the litter dry.

Remember that litter floors are the environment that the birds live in, including walking and standing.  The litter volumes on floors should be adequate to supply a soft walking surface for the bird.  It also should be deep enough for water absorption from the flock.  All other associated flooring, including slats, perches and other resting devices need to be in good condition to eliminate any foot pad injury.   Good housekeeping of the floor will aid in keeping the flock in good step.

Old McDonald in a New Light

We are not in Kansas anymore...

I spent the week at the PA farm show this month. This year PennAg Industries put together a live animal exhibit called "Today's Agriculture". Inside the commercial building were animals depicted in their commercial enclosures for their particular needs.
Almost to the person, most were very impressed with how all the needs of the animal were being cared for. Most were fascinated that we can keep animals in confinement and yet have them flourish if given the proper environment.

What this great exhibit reminded me of was that we sometimes hang onto old ideas, like Ol' McDonald's farm. Old McDonald had to become more efficient and produce more product as margins for his product decreased. It is amazing to think of all the developments that have continued to make our food the most plentiful and safest in the world. The people who went through that display saw firsthand how their food is produced. We should do more to promote that dialog. One such place is Farmers Feed Us that discusses how some of our foods are grown. Take a look and see. picture credit: Sarah Weeda

Preparing for Bad Weather

Could of - Should of - Would of ...

Many farmers often are too busy to think about emergency preparedness until the storm is upon them. That is the worst time to plan for an emergency. Fire departments do not take delivery of a fire engine only when a house is on fire! So it pays to be prepared, to be a good scout, and be ready for the most common threat to your farm and your livelihood. For small flocks, it too is important to prepare as the birds you keep are important to you as well (some have names!) so, it is important to have an emergency plan to enact when trouble strikes.

Anyone with animals should have a plan to take care of them if a supply falls short or fails altogether. For poultry, water and power is important to maintain in constant supply. As a storm approaches, it is important to take stock of critical equipment on the farm and make sure it is in operational order. Fuel and oil levels on backup generators, extension cords for backup generators, switching equipment and emergency pumps are valuable tools for farm backup supplies.

For water supplies, if running on a tank / cistern system make sure that pumps are keeping pool levels high in order to ensure supplies during a power outage. Barrels of water for small flocks can ensure a constant supply.

Check drainage routes on the farm and clear away any debris from gutters / spouting and culverts to ensure drainage away from poultry shelters and barns. If there are bridges that lead onto the farm be sure to check those too to make sure they are free of trash that could clog the bridge and cause a wash-out.

Logistically, you should have a call list of people that can help you. Township, county and other agency numbers in addition to integrator numbers should be handy. Check (Google if you have to) governmental websites for current numbers and contacts.

Personally, you should have a family plan as well. Have an outside the area contact that can call family on your behalf should disaster strike. Many times an area code will turn to one- way traffic (outgoing) in an emergency to keep phone lines open. Plan for that as well and give your out of area contact a list of who to contact in an emergency. Be sure your home has enough food and water for all occupants for 3 days without power. Be sure your cell is fully charged and that you have a way of charging it (car, batteries, etc.) without plugging it into a wall.

Combating Heat Stress

Boy, is it hot out there!

With the recent heat wave moving through the US, we are all reminded of what we can do to make poultry more comfortable, and hopefully get them to survive.

Water is the saving elixir in heat. Due to its physical properties of heat energy, water can aid in the cooling of flocks. Flushing the watering lines with cool water may aid in getting hot birds to drink. Do not flush water lines for chicks as you risk the chance of cooling the chicks below their optimal core temperature.

In addition to flushing drinking lines/fonts, spraying the outside of the house (roof, sides and surrounding grounds) with water will drop the ambient temperature of the area a few degrees due to evaporative cooling. In humid climates this may not work well. To test, place a wick on a thermometer and dampen it with distilled water. The ability to cool with evaporation will be shown as the temperature will drop as it cools. Five degrees depressed temperature can make the difference in some flocks.

Shift some feedings to feed the birds during the coolness of the night if possible. Heat builds up in birds as they metabolize their feed. Cool air aids in getting birds to eat in hot periods.
