BQA: General Refrigerator Maintenance
All refrigerators require general maintenance, and it is important to keep the refrigerator coils clean. Refrigerator coils are located in the rear of the refrigerator and can be cleaned by vacuuming the vents and coils. Dusty coils have to work harder to cool down the interior and contents of the refrigerator.
The drip pan, located beneath the refrigerator, should also be cleaned. In automatic defrost models, the water from the defrost process flows out a drain in the floor of the refrigerator and into a pan where it sits until evaporating. Food particles can be carried along and clog the drain or be left behind to rot. You can clear out the tube that carries particles to the pan by removing the stopper at the opening. Stick a pipe cleaner or similar device into the opening to push any particles through to the pan. Flush with soapy water and then empty and clean the pan.
The gaskets are the seals that keep cold air in and the room air out of the refrigerator, and the gaskets should last the life of the refrigerator if properly cared for. Gaskets should be washed with soapy water, and the "paper test" can be used to test the condition of the gasket. You should not be able to slide a piece of paper between the rubber seal and the wall of the refrigerator. If the piece of paper slips between the seal and the wall, the seal is not tight enough and the gasket requires replacement.
Consider the location of your refrigerator and/or freezer. Do not position them in direct contact with hot appliances as this will make the compressor work harder. Regularly defrost manual defrost freezers, never allowing frost to build up more than 0.25 inch.

This demonstration assisted producers in determining if they are storing animal health products according to labeled instructions. When animal health products are stored incorrectly, their effectiveness may become compromised. All animal health products that are past their expiration date or opened should be disposed of properly.
Protecting Water Quality and Good Grazing Management Go Hand In Hand!
Dr. Dirk Philipp, Assistant Professor
Yes, that's correct: If pastures are managed in a way that provides profit for the livestock operation, then you are a good steward of natural resources as well.
Unfortunately, there is the perception that protective measures for the quality of our rivers and lakes come at a high cost to producers. The truth is, with relatively simple measures, water quality can be protected, making the operation more competitive.
Water quality may get compromised when an essential plant nutrient – phosphorus (P) – gets transported away from the farm and ends up in surface waters. There, it can stimulate algae growth to such an extent that there is almost no oxygen left for other forms of life, and the affected rivers or lakes become uninhabitable for most other plant and animal species.
Historically, P was not much of a problem in animal operations. Farms with low soil P had little P loss, resulting in recycling of nutrients on the same land. With increased intensification, however, livestock operations have become a net source of P. This element is brought onto farms as part of concentrated feed or chemical fertilizer. Especially in Northwest Arkansas, P is brought in as part of the feed for poultry operations. Animals do not utilize P efficiently, so most of the P fed is excreted and present in relatively large concentrations in manure or litter. Grazing cattle redistribute plant nutrients very unevenly, and high concentrations of P are deposited in heavy-use areas of the farm or spot-like across a pasture. During rain events, P located on the surface of pastures or high-traffic areas can easily be transported away from the farm site and transported to nearby waterways.
However, by implementing a few best-management practices (BMPs), farmers can maintain an environmentally sound operation and save money. First, adjust the stocking rate according to the land's carrying capacity. Several factors affect carrying capacity, including available forage, animal age, species composition, soil type and physical characteristics of the pasture. A common mistake is a stocking rate that exceeds the carrying capacity of the pastures. Overgrazed pastures tend to be prone to erosion, have increased runoff potential, and are sensitive to soil compaction. At the same time, forage growth is poor with negative implications such as a low canopy that restricts forage intake and stressed plants that have few resources left for regrowth. If pastures are better managed in those cases and stocking rates adjusted, farmers will experience increased gains per animal, a greater amount of available forage and, ultimately, increased longevity and health of their pastures. At the same time, runoff potential is reduced through increased soil cover, and a taller canopy that breaks the impact of rain can hold back sediments during large storm events.
An effective way to link water quality protection with an improved livestock operation is the management of riparian zones. Whenever cattle have access to streams, they damage streambanks and linger in the water, while defecating and urinating at the same time. This behavior essentially wastes money by allowing the cattle to transfer plant nutrients to the stream. Once the nutrients are floating downstream, they are gone. Moreover, cattle health is compromised by allowing the cattle to drink water from sources contaminated with their own excrement, which will surely result in poor animal health over time. This applies especially to retention ponds that offer nothing else than muddy, lukewarm water to cattle. An easy solution is to fence your stream (or pond) with polywire about 50 to 100 feet away from banks and allow controlled access for grazing as part of a rotational grazing scheme. This will not only keep vegetation lush to filter runoff but also maintain forage with high quality that will give the cattle an additional boost when they graze these areas.
Another solution for keeping cattle away from streams is to provide them with watering sources right on the pasture. These devices can be cutting-edge, such as gravity pumps feeding into concrete troughs, or less sophisticated but reliable and cost-effective, such as old tractor tires cut in half and fed through a water line. A picture is included with this article. By installing off-stream watering sources, the cattle are provided with clean, fresh and cool water, all of which they prefer over any stream or pond they have to climb into. To reduce heat stress in cattle during hot summer months, provide natural shade or other structure on your pastures.

Records Can Help in Making Tough Decisions
Brett Barham, Assistant Professor
There is no doubt, with the increase in fuel, feed and fertilizer prices, that farm profits will be affected. The increase in these costs has many producers wondering how they will cope with the increasing costs to produce a calf. How a producer adapts his or her management strategy may determine if the balance statement is in the black or red at the end of the year. Producers will have to make some tough decisions to adapt to these changing times. Do I fertilize all my fields, some or none? Do I need to continue to cut my own hay or purchase it? Do I need to adjust my stocking rate to account for changes to my fertilization and pasture management changes?
These are all difficult questions, and the answer will not be the same for everyone. They become easier to answer if you have some records to look at. When it is time to cull cows, sometimes the choice is easy – maybe she is open or maybe she is too old to continue a productive life. What if you need to cull more than the easy choices give you? If you have to cull additional cows, it would be nice to be able to cull the least productive cows and leave the better producing cows in the herd. Without records that task becomes very difficult.
Your local county extension agent can help with collecting this type of information through the Cow Herd Performance Testing Program. As in any recordkeeping program, identification of cows and calves in the Cow Herd Performance Testing Program is a must. You have to be able to tell what calf belongs to what cow for the records to be helpful. Then there are just a few simple things for producers to record throughout the year. These include calf birthdates along with weaning weights and the date of weaning. Recording birth weights and calf sires would be beneficial, but not a requirement. Once these records are compiled, the local agent can help producers find cows that are below average in their producing ability. Research conducted in Arkansas shows that cows that are in the lower one third of the herd for productivity stand a very high chance that they will be in the bottom third year after year. In another words, cows that are low performers in any given year will probably always will be low performers. Additionally, these records from the cow herd performance program can help producers retain heifers that have the greatest genetic potential to be productive cows. If sire information is known, this data can help producers identify a bull that may be producing calves with lighter weaning weights.
The more records you keep, the more informed you will be about your operation. Some of these records can be budget related. How much did you spend on feed and minerals this year? Once you put together some rough financial records, it is easy to find places you may be spending more money than you need to. Others could be related to pasture usage and management. How many head-days did cattle graze each pasture? How many bales did you cut from this pasture and how much did they weigh? Some of these may seem trivial, but once a producer starts looking at the bigger picture, he or she might be able to find trouble spots. It might cost you more to bale your own hay than what you could have purchased it for.
Keeping records also may help on the income side of the business. There are many programs available to producers that reward them for keeping records on their cattle. One of these type programs is the Arkansas Age and Source Verification program. If you are able to identify calves and have records on their birthdates, you will be eligible to receive a premium at the time of sale for certifying your calves as source and age verified. For more information on the requirements for this pro gram, contact the Arkansas Livestock and Poultry Commission.
Another way that keeping records will help in the marketing of calves will be in compliance with Country of Origin Labeling (COOL). COOL is a mandatory program that is scheduled to be implemented September 30, 2008. While it is still unclear what kind of records will be necessary to comply with the rules of COOL, keeping the basic records such as cow and calf IDs and birthdates would go a long way in meeting any requirements. For more information on record-keeping ideas for cattle producers, please visit with your local county extension agent.
Accurate Feeding Management for Your
Horse
Steven M. Jones, Associate Professor
There are a number of considerations in the husbandry or "art" of feeding horses. Once a horseman understands the nutrient requirements of various classes of horses, a certain amount of skill and sound judgment must be employed in developing a feeding management program. After feeds are selected to meet the nutritional requirements, it is important to adhere to certain principles to accurately feed the horse. These principles include a) feed horses by class; b) feed horses according to body weight; c) feed adequate long-stemmed forage; and d) feed by weight, not volume.
Horses require differing amounts of nutrients in their daily diets depending on their nutritional class or status in life. Dividing horses into classes relative to nutrient requirements is the first step in designing a workable feeding management program. This approach helps a horse owner meet each horse's nutrient requirement in the most manageable and economic fashion. Weaned foals, lactating mares and hard-working horses have the highest nutrient requirements. Mature, idle horses have the lowest nutrient requirements.
When determining body weights, the most accurate method is to weigh the horse on a scale. The least accurate method is visual appraisal or "guess." One study reported that 88% of horsemen, many of them professionals, underestimated the weight of five horses by an average of 180 pounds. In another field study, 37% of horse owner estimates were 150 pounds below actual weights. Probably the most commonly used "accurate" technique for estimation of body weight is a heartgirth tape. Heartgirth tapes are available at feed dealers or livestock supply companies. When used according to instructions, these tapes are reasonably accurate. Another method for estimating a horse's body weight is use of a body weight equation. One accurate formula utilizes heartgirth circumference, body length and an adjustment factor. This equation is:
| (heart girth x heart girth x body length) |
|
330 |
= weight in lbs.
Measurements should be taken and recorded in inches with a tape at least 75 inches long. A plastic tape is preferred over a cloth tape. Cloth tapes can stretch, and metal tapes may scare horses. Heartgirth is a measure of the circumference, taken by running the tape all the way around the horse using the highest part of the withers. Body length is measured from the point of the shoulder, straight along the horse's side, and to the point of the buttock. In two demonstrations conducted at Texas A&M, this equation averaged being within 24 pounds of actual weight. On an 1,100-pound horse, this is close enough for making nutritional decisions.
Long-stemmed forage for horse is a necessity, not a luxury. A horse requires at least 1% body weight of long-stemmed forage to maintain normal digestive tract function. Horses grazing abundant good-quality pastures consume enough green, growing forage to meet their daily roughage requirements. Horses maintained in dry lots or stalls receive only what roughage is fed to them by their owners. When adequate long-stemmed forage is fed, horses appear satisfied and stall behaviors are normal.
Horsemen should feed by weights of feed, because standard volumes of feedstuffs do not weigh the same. For example, the horse owner's universal measuring dispenser is the 3-pound coffee can (if you can still find one). When full of 32 lb/bu oats, the can weighs 21⁄2 pounds; 38 lb/bu oats weighs 4 pounds; pelleted feed about 4 pounds; and whole corn may weigh 5 pounds or more. Concentrates do not weigh the same! There is even a difference in weights of hay due to type of forage and dry matter in the bales. Always check feed weights, especially when new or different feeds or hays are purchased. Mark cans and other feed dispensers to standardize amounts of feed being fed.
The basic concept of designing a horse feeding program is to know the nutrient requirements of the various classes of horses and the nutrient contents of the available feedstuffs. After these elements are established, then we combine "art" and science by feeding horses according to body weight, feeding adequate long-stemmed forage, and feeding by weight, not volume. This is the most economical method for feeding horses, plus it's the best method for the horse and its health.
Getting Started With New Beef Cattle
Projects
Steven M. Jones, Associate Professor
Deciding which type of beef project to exhibit can sometimes be the most difficult decision the 4-H member is asked to make. Haltered show steers and heifers demand time, discipline, expense and work. Market steer and commercial heifer programs are outstanding beef training projects. These projects educate 4-H members on economic strategies to feed and manage animals to market or for commercial cow-calf production.
After deciding on a type of project, it is time to begin the selection process. Practice, patience and experience will help the 4-H member properly select the project. It is a good idea to evaluate several young projects before deciding on one. It is very important for each 4-H member to ask someone else to accompany and assist them during the selection of projects. Usually, county extension agents, agricultural science teachers, ranchers, breeders and experienced exhibitors offer the best advice.
There are selection criteria each 4-H member should consider during the process of selecting market steers or commercial heifers for show. Before selecting the steer or heifer for show, consult your county extension agent for county, regional, state or national rules governing the exhibition of your project. Then age, frame size, weight and breed are all important to coordinate for specific shows and dates for the show. Rules of the intended show should be studied carefully for specific guidelines, such as ownership dates, minimum and maximum weights and ages and class divisions. Important selection criteria are age, weight, frame size and breed or breed types.
Age: Actual age and birthdates are very important. The age of a steer or heifer when placed on feed will vary from 6 months to 10 months. Most calves are weaned at approximately 6 to 7 months of age. Steers can reach slaughter point from 14 to 20 months of age, and heifers should reach puberty to breed between 14 to 16 months of age.
Most steers are exhibited at 16 to 20 months while heifers may be shown to 24 months of age.
Weight: Steers intended to be exhibited at major fall shows (those from September to November) are normally placed on feed in December to February, weighing approximately 400 to 600 pounds. This should allow the steer to reach 1,100 to 1,300 pounds in October, accounting for reduced weight gain and shrink due to training, fitting, conditioning and hauling. Show steers are normally on feed approximately 270 days and gain between 2.0 and 3.5 pounds a day. This rate of gain and growth can be slightly controlled by regulating the feed ration and amount fed for faster or slower gain.
Frame Size: A numerical frame size is generally correlated with growth and can be used to predict final height that correlates with definite mature weight ranges.
On average, steers grow approximately 3⁄4 inch in height per month from weaning to finishing, and gain ranges from 2.0 to 3.5 pounds per day. The 4-H member can predict the final height of a steer by knowing the exact age and height of the animal at any given time. Referring to a Beef Cattle Frame hart, match up the age in months with the hip height in inches. The most popular frame sizes are 4 to 6 for ideal show cattle height on show day.
The following tips should be helpful in developing future champions in the show ring:
1. Cattle are creatures of habit and have good memories. Develop a routine and follow it each day. A daily routine makes chores much easier. For example, exercise the calf, show it by setting it up, and make it stand properly, then brush it and feed it last.
2. Weigh the calves periodically to monitor gain. Decide on the weight class (steers) in which you want to show your calf and shoot for that weight. Old class breakdowns from previous shows are very helpful in determining desired weights.
3. To be a good showman you need a well trained calf. A calf should be taught to stop and lead, with his head up. A good daily practice is to pull the calf's head up to a stop so both front feet are placed squarely under the front end. Using a show stick with a blunt point on the end, teach the calf the use of a show stick by stroking its underline while tied. Stroke the animal, then place the foot in the correct place. After the calf sets its feet properly when tied, then it is ready to be led and have its feet placed while being held by the exhibitor. Teach the calf to keep its top line level and to lead and walk freely.
4. When training calves or working and brushing hair, it is best to tie the calves to a high rail rather than placing them in a blocking chute. Working cattle in this manner makes them easier to handle and more accustomed to strange movements at the show. Before washing the calf, remove dirt and manure from the hair with a comb or brush. An electric blower will help in this process.
