Farmers Breakfast Tuesday, March 25th The Bracken County Ag Advancement Council, the Agri-Business Community and the Extension Service, will once again host the annual Farmers Breakfast. Due to the great success of the annual event, these groups are now planning for the 2014 breakfast. It will be held on Tuesday, March 25th from at 7:30 – 10:00 AM at the extension office. All producers are welcome to attend and join in conversations on agriculture issues, learn about upcoming extension programs, and just enjoy some good fellowship and outstanding food. Due to the limited parking, make plans with your neighbor to car pool to the breakfast. Extra parking will be available at the white barn located between the extension office and the water office. Many new extension publications will be available, including all of the forage and grain variety publications and many management handouts. The 2014 Beef Calendars which have monthly management information will also be available and Farm Record Books will be for sale. This will be an excellent chance to learn about projects taking place in the county and a chance to visit with other producers before the busy spring season begins.

Oran Little Research Center in Versailles May 21-22, 2014. This two day program features the latest, practical information on “grazing” with both classroom and field activities. Registration is $50 and includes all handout materials, grazing manual, breaks and lunch both days. The class is limited to the first 45 to sign up. Please call the office if you are interested in attending. Fruit Tree and Grape Spraying The most important disease prevention sprays you will make on both fruit trees and grapes is before buds open or right at the end of dormancy. Any delays in spray applications result in less than optimal control. Now is the time to determine what chemicals you need and have them on hand, ready to apply at the right time. The UK publication, Disease and Insect Control Programs for Homegrown Fruit in KY is available at the office. It has spray schedules and chemical recommendations for each phase of the plant development with a description and pictures of the fruit buds as they develop. This is also the time to prune these plants which also helps in disease control. Prune out any diseased plant growth and reduce any excess growth for more air flow which helps dry the for first-calf heifers) may be needed if you are feeding lower quality hay. Supplementation may have a beneficial effect on date and rate of conception. The most important time to feed a beef cow is after calving. Thin cows don't come into heat very soon after calving. We must have cows in good condition, if we plan to breed them early in the season for best pregnancy rates, especially on high-endophyte fescue pastures. leaves. Remove all diseased or dried, left over fruit or leaves, on or around the tree as these will serve as a source of inoculums for new infections. Timely Tips for Beef Herds Watch for scours in newborn calves. Consult your veterinarian for diagnosis, cause, and treatment. Obtain fecal samples and submit to diagnostic lab, if scouring begins. Dr. Roy Burris, UK Beef Extension Specialist Overall condition of the cow herd should be evaluated. Cows losing weight now are most likely to have weak or dead calves. These cows will likely be a poor source of colostrum milk for the newborn calf. Feed cows, if necessary to keep them in good body condition. Separate cows that calve away from dry cows and increase their feed. Avoid muddy feeding areas so that cows' udders won't become contaminated and spread scours. Don't confine cows to muddy lots. Have calving equipment, supplies and labor ready for the spring calving season. Some supplies which may be needed are: eartags and applicator, tattoo pliers and ink, record book, scales for calf weights, iodine for calves' navels and colostrum supplement. Calving equipment and facilities should be ready and clean. Replacement heifers should be gaining adequately to reach target breeding weights by May 1. Be sure that their feeding program is adequate for early breeding. You should be feeding a mineral supplement with adequate magnesium to prevent grass tetany (~ 15% Mg) now. The Hi-mag UK Beef IRM mineral can be used now. Heifers should begin head-start calving in early February. Move them to a clean, accessible pasture, away from cow herd and near facilities so that calving assistance can be given. Cows may start calving later this month. Signs of calving are relaxation of pelvic ligaments, enlargement and swelling of the vulva, and enlargement of the udder. Expect calving difficulty if (1) calf's head and two feet are not visible, (2) only the calf's tail is visible, and (3) the cow has been in labor for 1½ hours. Be sure calf is being presented normally before using calf puller. Recognize situations that are beyond your capability and seek professional help as early as possible. Calves that aren’t=t breathing should receive assistance. Try sticking a straw in nostril to stimulate a reflex or try alternate pressure and release on rib cage. Commercial respirators are also available. Calves should consume colostrum within 30 minutes of birth to achieve good immunity. Start looking for herd sire replacements, if needed. Control lice. Watch for signs such as rubbing. Begin pasture renovation. You can overseed clover on frozen or snow-covered pastures. Poison Hemlock Control Program One of the very first plants to start growing after winter is Poison Hemlock. This invasive weed is becoming more prevalent throughout the county and is a great concern with our livestock industry. For many years, plants were only found along fencerows, feeding areas and barn lots. Now it is not uncommon to find plants in pasture and hay fields. Due the plants extreme toxicity, and the potential to kill livestock, control measures need to be implemented to prevent the contamination of hay with this weed. A fatal dose can be as little as one half of one percent of an animal’s body weight of the plant material and all parts of the plant are equally toxic. Herbicide applications need to be made right away while plants are small and easily controlled. Products that are recommended include 2,4-D products, products containing triclopyr, and products containing glyphosate. Record birthdate, cow I.D., and birthweight immediately. Identify calf with eartag and/or tattoo. Registered calves should be weighed in the first 24 hours. Male calves in commercial herds should be castrated and implanted as soon as possible. Sub-zero weather can mean death for newborn calves. During extremely cold spells, bring the cow(s) into a sheltered area as calving approaches to protect the calf. Be prepared to warm-up and feed newborn, chilled calves. Calving in mud can also cause problems. Increase feed after calving to 25-27 pounds of high quality hay. Concentrate (3-4 lb. for mature cows and about 8 lb. 2 were cycling in the first month of the breeding season (June) was considerably lower than for cows that were in more moderate body condition. During the second month of the breeding season, 55% of the cows with a BCS of 4 had still not initiated estrous cycles, while more than 90% of the cows in more moderate condition had begun to cycle. Thin cows need a longer breeding season, which results in more open cows in the fall. They may also result in lighter calves to sell the next year because the calves from these thin cows will be born later in the calving season. For general broadleaf weeds in pasture, 2,4-D type herbicides will control many of the early season weeds. For more woody type weeds such as briers, a stronger herbicide will be needed. Herbicide selection guidelines are available at the office to determine which product best matches your weed problems. Preparing Cows for Breeding A successful breeding season actually begins with management decisions made at calving. Cattlemen can impact rebreeding efficiency by focusing on body condition score (BCS), early assistance during calving difficulty, scheduling a breeding soundness exam for the herd sires, planning their herd reproductive health program, and developing a plan to regulate estrus in their first-calf heifers and late-calving cows. Management of BCS after calving also impacts rebreeding efficiency. Maintenance requirements for energy and protein increase 25-30% for most beef cows after calving. Ranchers need to plan their supplementation to match or exceed this increased nutrient requirement. Rebreeding efficiency is enhanced in cows that calved thin if their energy intake is increased. Although the best management plan is to calve cows in a BCS of 5+, increasing the energy to cows that are thin at calving can boost reproductive performance. Reproductive management begins with evaluation and management of BCS. Body condition score is a numerical estimation of the amount of fat on the cow’s body. Body condition score ranges from 1-9; 1 is emaciated while 9 is extremely obese. A change in a single BCS (i.e. 4-5) is usually associated with about a 75 pound change in body weight. Evaluation of BCS prior to calving and from calving to breeding is important to ensure reproductive success. Dystocia can severely delay the onset of estrus after calving. Research shows that for every hour a female is in stage 2 active labor there is a 4 day delay in the resumption of estrous cycles after calving. Early intervention helps; 16% more cows conceived when cows were assisted within 90 minutes of the start of calving. The best method is to reduce the incidence of dystocia via selection but early calving assistance will increase the opportunity of cows to rebreed. Rebreeding performance of cows is greatly influenced by BCS at calving. Cows that are thin (BCS < 5) at calving take longer to resume estrous cycles and therefore are delayed in their ability to rebreed. Research has clearly demonstrated that as precalving BCS decreases, the number of days from one calving to the next (calving interval) increases in beef cows. Females with a precalving BCS of less than 5 tend to have production cycles greater than 1 year. For example, cows with a precalving BCS of 3 would be expected to have a calving interval of approximately 400 days, while a cow with a precalving BCS of 6 would have a calving interval of approximately 360 days. South Dakota research illustrates the influence of precalving BCS on the percentage of cows that initiated estrous cycles after calving. This experiment demonstrated that the percentage of thin cows that A tool that can improve reproductive performance is breeding soundness exams in bulls. Ranchers need to think of breeding soundness exams as breeding season insurance. These exams are a low-cost method of insuring that your bull is not infertile. Bulls should be examined for breeding soundness about 30 days before they are turned out. Dr. Les Anderson, UK Beef Extension Specialist Several diseases are associated with reproductive loss (lepto, BVD, vibrio, trich, etc). The main problem is that most reproductive loss due to disease is subtle and ranchers don’t notice the loss unless they have a massive failure. Most cattlemen are not aware of their losses due to abortion. Ranchers need to work with their local veterinarian to develop an annual vaccination plan to enhance reproductive success. 3 Managing for reproductive success actually begins at calving. Cows need to calve with a minimum BCS of 5 and with little assistance. Effective planning for reproductive health and management plan for limiting the impact of anestrus will ensure that cattlemen are happy, happy, happy at the end of the breeding season. Do not add fertilizer until after plants have germinated and have at least 2 leaves. Use only recommended float bed fertilizer. If using old trays, you need to use Terramaster in the float water to control Pythium. Even if trays are sterilized with the bleach, Pythium organisms will still cause major losses in the float bed and in the field. Apply Terramaster no sooner than 2 weeks after seeding and no later than 3 weeks after seeding to avoid plant damage. Waiting until the disease is present can result in major damage to plants and long delays in plant growth. Tobacco Float Bed and Greenhouse Management To calculate the amount of water in your float bed, use this formula: Depth of water in inches X Number of trays X 1.64 = Gallons Ventilation is a major key to disease prevention. Warm air trapped in a greenhouse or float bed holds more moisture than cool air outside. Air out greenhouse at the end of the day to avoid moisture buildups and dripping at night. With a very successful tobacco market this past year, many producers will soon be starting another crop. There are a number of guidelines you need to follow to make sure your plants are as disease free as possible. Start spray schedule on weekly intervals once plants reach the 4 leaf stage. The only chemical that is labeled for use in the weekly spray program is Manzate Pro-stick. Dithane DF and Penncozeb are no longer labeled for tobacco use. Growers must have a 24(c) label in their possession to use Manzate Pro-stick. This label can be obtain from your dealer, the extension office or the CDMS website at www.cdms.net Variety selection – review the list of varieties in this newsletter and determine which variety will best meet the needs of your farm. If Black Shank is a problem, notice that TN 90 is very low in resistance. Many varieties are better choices for this disease. Do not allow plant clippings to drop into the canopy. Dead plant material is a major cause of disease. Sanitation – sterilize old trays by washing off dirt, dipping them in 10% bleach solution, and then wrap them in plastic while wet with the bleach solution. After 24 hours, remove them from the plastic wrap and rinse off the bleach residue. The chlorine gas provides the best possible sterilization of the trays. Calibrate your meter and make sure and maintain proper fertility levels in float water. Last year, low fertility levels resulted in major outbreaks of Target Spot. Quadris is now labeled for one application in the greenhouse or float bed to control target spot. This application needs to be made after the first clipping. The rate is 4ml. in 5 gallons of water and applied to 400 trays (1000 square feet). A 24(c) label must be in your possession for Use only new plastic and clean water for the bays Use new soil media. The wetting agent in old soil media breaks down over time and may cause problems with dry cells. 4 Quadris use the same as above. After this treatment, return to the weekly spray program using Manzate Pro-stick. Signs of Hypothermia Faced with a cold environment, the body defends itself in two ways: shivering, to increase muscle heat production, and blood shunting, to reduce heat loss by diverting blood flow away from the body extremities to the body core. Mild hypothermia occurs as the body's core temperature drops below normal (approximately 100° F. for beef calves). In the early stages, vigorous shivering is usually accompanied by increased pulse and breathing rates. Cold nostrils and pale, cold hooves are early signs that blood is being shunted away from the body's extremities. In the case of newborn calves, severe shivering may interfere with its ability to stand and suckle. Erratic behavior, confusion and a clumsy gait, are all signs of mild hypothermia. Producers often refer to these as "dummy" calves. Severe hypothermia results as the body temperature drops below 94° F. Shunting of blood continues, manifesting as cold and pale nostrils and hooves. For more information on Tobacco Disease Control, stop by the office and pick up a copy of the 2014 Fungicide Guide for Burley Tobacco. Cold Stress & Newborn Calves Michelle Arnold, DVM (UKVDL) When the weather is predicted to be bitterly cold, producers should take extra care of newborn calves to ensure their survival. A calf’s body temperature often falls below normal in extremely cold conditions due to a slow or difficult birth (dystocia) followed by delayed standing and nursing. Returning the calf’s core body temperature to normal (100° F for newborn calves) is of immediate concern then maintaining that core temperature is of secondary importance. If at all possible, bring close-up cows indoors to calve in a heavily bedded, clean pen. If calving outdoors, make sure there is dry, clean ground available for the cows to calve without a large amount of manure. If the cow calves outdoors, bring the calf in until warm and dry if the calf is showing signs of hypothermia or if there are no natural windbreaks available. Treatment of Hypothermia The two most important factors in calf survival are warmth and colostrum. Before giving colostrum, a chilled calf first needs to be warmed as these newborns are typically too weak to suckle. Karo syrup (dark is preferred) delivered by mouth to a weak calf is a quick source of readily available energy and is rapidly absorbed through the mucosa in the mouth into the bloodstream. Effective methods to warm a calf include: 1. Floor board heaters of pickup trucks. 2. Submersion of wet calves in a warm bath-you must support the calf to prevent drowning. The water should be gradually warmed to 100° F and will need to be changed to keep it at that temperature. There are two types of hypothermia: exposure (gradual) and immersion (acute). Exposure hypothermia is the steady loss of body heat in a cold environment through breathing, evaporation and lack of adequate hair coat, body flesh or weather protection. This type of hypothermia affects all classes of livestock but particularly affects young, old and thin animals. 3. Placing calves next to the heater in the house and/or using a blow dryer to dry and warm the hair coat. Never leave calves unattended next to a portable space heater. Immersion hypothermia is the rapid loss of body heat due to a wet, saturated hair coat in a cold environment. Immersion hypothermia often occurs after the birthing process because the calf is born soaked with uterine fluids. Other causes of immersion hypothermia of young calves may include being born in deep snow or on wet ground, falling into a creek or being saturated from heavy rains followed by chilling winds. 4. Placing the calf under a heat lamp-be careful to cover the lamp with a screen so the calf will not get burned as it becomes more active. 5. Warm blankets-These should not be so hot that they can cause skin burns. Change the blankets as needed to maintain a consistent temperature and not allow the calf to cool off. 5 Pasture Improvement Training March 26th at 6:30 PM Upcoming Meetings Soil Health & Cover Crops Training (Repeat of fall program) March 17th at 10:00 AM Both meetings qualify for the Phase I Educational Requirements. Attention: Tobacco Growers All those who plan to grow tobacco in 2014 will be required to obtain a Grower ID Card and attend Tobacco GAP Certification. Below is a brief description of the ID System and certification. The Grower ID System is a secure database of tobacco growers involved in the U.S. Tobacco GAP Program. The system, by assigning a unique ID number to each grower, will help growers easily keep track of and share their GAP compliance records with potential companies. Instead of a grower’s GAP efforts being tracked only through their current contracting companies, growers will have their GAP information follow them from year to year regardless of marketing company. Temporary cards can be obtained by visiting www.gapconnections.com or the Bracken Extension Office will provide this service as a courtesy to growers without internet access. Tobacco GAP Certification Training is scheduled for March 19, 2014 at the Mason County Extension Office. This certification will be a two tier offering for that evening. Producers who did not participate in training last year should arrive at 5:00 PM and producers who did attend last year should arrive at 6:00 PM for an updated GAP Certification. 6 Cooperative Extension Service University of Kentucky Bracken County 1120 Brooksville Germantown Rd Brooksville, KY 41004 NONPROFIT ORG US POSTAGE PAID MAYSVILLE KY PERMIT #13 RETURN SERVICE REQUESTED 7
