Heifer Tips are seen bimonthly in Dairy Herd Managment's Calf and Hiefer Advisor and archived on the DCHA Web site. Have a tip you'd like to share? Submit it to: info@calfandheifer.org. Feeding free-choice water to wet calves year-around is an important priority to Mike and Patty Strayer, owners of Strayer Dairy, Wadena, Minn. Trouble is, it can be a cumbersome task. The Strayers contract-raise wet calves for seven dairies plus their own lactating herd, with 300 calves on milk in hutches at any given time. They use a cart pulled by a four-wheeler to distribute water among the hutches. To speed up the filling process, they store water in a 600-gallon recycled milk bulk tank. A ½-horsepower sump pump rigged up with PVC pipe and discharge hoses fills the water cart in approximately five to six minutes. “In the winter, we install a heater in the bulk tank to warm the water for feeding,” adds Mike. “It heats it to about 70°F in the winter, and keeps it cooler in the summer than a poly tank would, even though we don’t use the refrigeration unit. It’s an invention that has saved us countless labor hours and headaches.” Ron and Marianne Scherbring of Scherbring’s Heifer Heifer Hotel, Minnesota City, Minn., have rigged up a handy and inexpensive way to dry feeding pails after washing them. “We’re feeding 400 wet calves at any given time, and try get them drinking milk out of pails as quickly as possible,” explains Marianne. “As our operation grew, it became an issue of where to store the pails after washing, to both keep them out of the way, and to make sure they are sufficiently dried.”
Because the pails do not touch one another or the floor, the risk of pathogen contamination also is decreased. When Mike Davis took over as manager at Harrah Feedlot, Wapato, Wash., about a year ago, one of the trouble spots he noticed was that the Holstein heifers raised at the feedlot were not expressing strong heats. As a result, they were difficult to detect in heat, and breeding goals were not always being met. The operation raises about 5,000 heifers a year for a neighboring dairy, and lagging breeding dates leading to older-than-necessary replacements were impacting the success of both operations. “I’m convinced a change in nutrition is what turned it around for us,” says Davis. He explains that heifers were being limit-fed to encourage use of lock-ups. However, feeding a larger volume of TMR has improved heat expression and detection dramatically, without impacting lock-up use behavior. “I think they just needed more nutritional resources to address both growth and reproduction,” Davis notes. Heifers now are bred to freshen at approximately 21-23 months of age. He adds that over conditioning, another initial concern with the increased feed volume, has not been a problem. “We’ve worked closely with our nutritionist to help us walk that fine line,” says Davis. “Like everyone else, we really struggle to keep feed costs down, and we use byproducts whenever we can. Some may say it’s expensive to feed more, but we have concluded that unnecessary days open and delays in getting grown heifers into the milking string are an even greater expense.”
However, if desired cuts contain injection-site lesions, then the added value disappears. For example, damage to the top sirloin alone from an injection-site lesion can dramatically lower the slaughter value of a carcass. Because injection-site blemishes starting as early as calfhood may remain with the animal throughout its life, the Dairy Beef Quality Assurance Program advises calf and heifer raisers to follow these beef-quality-protecting practices:
“One of our large dairy clients was receiving pressure from their wet-calf grower to use an off-label vaccine protocol,” explains Gustafson. “We take their heifers after weaning, and felt very strongly that we should not deviate from the label.” A group meeting involving the dairy’s management; Gustafson; his herd veterinarian; the vaccine’s manufacturer representative; and the manufacturer’s technical services veterinarian, was very productive. “We ended up agreeing on an on-label protocol,” shares Gustafson. “But, just as important, we all walked away with a better understanding of our collective mission -- to protect the health and safety of the animals in our care, and those interests of the end consumer as well.” Because the proper administration of the vaccines and antibiotics is everyone’s responsibility, the Dairy Beef Quality Assurance program recommends strict adherences to the following guidelines:
Holstein steers are a different animal
“One of the things I love about them is that within 30 days of arriving at the feedlot (starting at approximately 300 pounds), we can have them on the hottest ration we feed,” says Davis. “We really bump up the energy using corn syrup and fat. You can’t do that nearly as quickly with a beef animal, and these dairy steers actually need it, so they don’t get too framey.” He adds that Holstein steers do need more pen space compared to their beef-breed counterparts. Most of the steers at Harrah are finished at about 1,380 pounds, and can be marketed starting at about 345 days after arrival. Davis says they have overcome the tendency toward smaller rib eyes by using a series of three TBA implants at 120-day intervals, starting when calves enter the feedlot. “Implants are not a replacement for optimal nutrition, but they can help you maximize a good nutrition program,” he states. Sean and Sandy Quinn and their team at Sunset View Farm, LLC, Schaghticoke, N.Y, are sticklers for sanitation. For example, they never want the transfer hose used to feed calves in his wet-calf barns to touch the ground. “We use 100 feet of milk-line hose to move milk replacer from a poly tank on the back of a utility vehicle to individual calf pails. It rolls up on a retractable wheel rigged to the unit,” Sean Quinn explains. To ensure that the hose doesn’t touch the barn floors, Quinn bent pieces of heavy cable covered with rubber insulation into “S” hooks and hung them over a cable which was already in place for shade cloth in each of the three, 50-head barns. “We simply loop the hose over the hooks as soon as we enter the barns, and start feeding,” Quinn says. “It’s an automatic element of our feeding routine, and helps prevent the spread of pathogens from one barn to the next.” Color-coded lists work well here Even with the tracking and list-generating capabilities of Heifer-ProTM software, workers at Amber Hills Ranch, near Rupert, Idaho, were sometimes confused about which animals needed what procedure at processing time. With more than 800 wet calves plus weaned animals to manage at the custom calf and heifer raising facility, it’s easy to understand why. “Most of our clients want their bull calves castrated, but some do not. And some want tails bobbed, while others don’t,” explains Bart Hanson, co-owner of the custom-heifer-raising facility. “It is important that every animal receive the correct procedures and vaccinations.” Linda Arata of Chowchilla, Calif. is more like a foster mother than a calf grower. “I’ve had calves in the kitchen and the bathtub — I’ve fed them on my lap — I’ve pretty much done everything short of sleeping next to them,” she says.
Arata takes pride in having an annual death loss of less than 1 percent. “I think more dairies need to appreciate calves for what they are,” she says. “They are the life and future of the dairy. Any extra investment of time or resources in calves pays off and then some in the future.” There’s nothing like shoveling bunks for inspiration. Huddleston, Va. veterinarian and custom-heifer grower Don Gardner says frustration with wasted feed provided the motivation to fine-tune feeding procedures at his heifer operation. Gardner and his son, Sam, raise weaned-to-springing heifers for four dairies, typically caring for about 700 heifers at any given time. Some feeding lessons they have learned include:
Feed bunk management is more of an art than a science, says Gardner. You learn what works and make changes accordingly. However, you also need regular weight checks of heifers to make sure your feeding system is delivering the intended growth rates. When treating weaned calves in group housing, Kristen Merle, calf manager at Lamb Farms, Oakfield, N.Y., uses a quick color-coded marking system to identify which treatment a calf received. “I use crayons to mark the heads of each calf that receives treatment,” she explains. Each of the four colors used — red, orange, blue and green — corresponds to one of four treatment protocols used in weaned calves. “This way I, or anyone else on our team, can look at a pen of calves and see which ones have been recently treated, and with what drug.” Merle also keeps a written record of each treatment, and enters it into an electronic archive on a Palm Pilot®. But she likes the convenience of being able to visually evaluate each treatment when she is out working with the calves. “This method also helps our veterinarian and me evaluate treatment outcomes of various products,” says Merle. “It makes it easy to walk by a pen of calves, see which ones have been treated, and assess if that treatment is working.” July 2007 Johanna Laggis, calf manager at Laggis Bros. Dairy, East Hardwick, Vt., uses inexpensive, digital thermometers from the local drugstore for temping young calves. “They’re quick, accurate and affordable, plus they’re much more convenient to use than mercury thermometers,” she says. Calf-management specialist Sam Leadley, with Attica (N.Y.) Veterinary Associates, affirms that the thermometers are fine to use on calves. “Just be sure to apply gentle pressure when using them, so that the thermometer is touching the wall of the rectum, and not temping air,” Leadley advises. And be careful where you store them, adds Laggis. “One time I took one out of my pocket and left it on the bathroom counter,” she recalls. “My son used it orally on himself.”
