A22-Uiuyster Farming, Saturday, March 7, 1998 Tastier (Continued from Pago At) Co. Down. His research has emphasized improving grazing management to increase intake and utilization of pasture. At the 1.000-acre institute, graz ing research has focused on inten sively grazed paddocks made up of ryegrass and grass sward combinations. Some of the strongest research has suggested, according to the scientist, that? animals prefer a cer tain type of forage the tetra ploids over the diploids. The tetra ploids have a higher sugar content and are easier to sheer and digest by ruminants, according to Mayne. Gradually, research emphasis has shifted from variety and maxi mum yields to “varieties that ani mals will eat more of,” said the northern Ireland scientist. Other strong evidence suggests that grazing animals prefer the “tall, erect varieties” of forage to the prostrate, or low- growing, plants at the research institute. Devices to measure how often an animal reaches for forage, tears it off, chews on it, and ruminates, are used in the research. And what the researchers have found, according to Mayne, is that the more the animal can bite off, the more it can handle by its jaws, the more forage it processes, which can translate into improved milking. Simply put, a “small increase in bite size has a major impact on grass intake,” said Mayne. Simply increasing the amount of forage taken in from 0.5 gram to 0.6 gram per bite increases overall intake by 20 percent. Sward height is also a key fac tor, Mayne noted. Cows prefer at least 4 inches of grass height Tall, dense, leafy swards lead to large bites, noted the grazing scientist In charts, the most intake came from swards measuring about 5-6 inches in height That’s why. according to May ne, it is important for graziers to control the grass left after grazing to ensure the height of the sward is suitable for the animals. Why go about looking into improving forage palatability and investing time in studying forage types? Mayne noted that, three years ago, milk prices in Ireland were, based on U.S. figures, about $lB per hundredweight Now. the price has dropped to $l2 a hun dredweight to the producer. And “all predictions see a further reduc tion to $lO a hundredweight in the next 2-3 years,” said Mayne, as European Union support prices continue to wither. The trend is downward for the beef industry, which went through some major crises with the “mad cow” disease scare. The continu ing trend, even for dairy producers, is an increase in size of units and a downward spiral for the amount of producers. Mayne noted that 20 years ago, there were 20,000 dairy producers in Ireland; that number has fallen to 6,000 today. Herd size, on average, is about 60 per farm. These “downward” trends are similar for the U.S. So the idea of using grazing as a way to cut farm costs, including mechanization and labor, holds more appeal for producers. As a result, the Institute has been tasked with looking at diffe rent varieties of the same grass species. Mayne noted that not all About ISO Attend State Con Forage, Bigger Bite Highlight Grazing ryegrass, for instance, is the same some have relatively improved dry matter and sugar content than others. Also, researchers ate looking at ways to make the grasses more drought tolerant And the tetra ploid varieties can have up to a 20 percent mote nutrients over the diploids, he noted. In Ireland, as in many places in Europe, producers are under increasingly stringent legislation for nutrient management The legislature penalizes farmers for not using controls. The idea of using abundant inexpensive sour ces for nitrogen for grain crops has been fading. Now, there is more accountability that is written into law. That even includes “unrecov ered” nitrogen the nitrogen simply released into the air. But along with the movement away from mechanization and the resultant high costs of mainte nance and repair, many producers still fail to understand that “graz ing is much more difficult to man age,” Mayne said. It’s harder to maximize management to graze effectively than it has been to simply go out and buy equipment and make the feed. No matter what the program, eventually stored feeding is impor tant and producers have to be able to implement a plan that will con tinue the forage intake. Also, there are some benefits to targeted grain feeding and can act as supplement to the cows when no forage is available. If storing forage, it is important to ehsure that respiratory and pro teolytic enzymes are available arid that detrimental organisms, including yeasts and molds, are not present in the seal. One item that surprised the sci entists at the Agricultural Research Institute was the supposed length of the glazing season. While traditionally the animals aren’t put out to pasture until April, studies looked at grazing in February on frosted grass. “The cows went out and were quite happy to eat the material,” available to them for about two hours a day from February into March. It is important for producers, if they want to use grazing on their operations, to determine how it will be implemented. There is less overall benefits for the cows if. as an instance, 70 per cent of the diet is taken in grain feeding/high TMR programs. The forage quality won’t bear much of a factor. But if forages will be used almost exclusively, quality bears a huge role in animal productivity. Overall the acceptance of graz ing continues unabated, even in northern Ireland. "The ’9os, I believe, will be the ear of grazing.” said Mayne. “I am convinced of that.” Other producers spoke of their experiences with grazing at the conference. One day, dairyman Lewis Stuttle got “sick” of the three times-a-day milking. “The pay back was not there,” he said, and some change was needed. Even though the herd average stood at 23,000 pounds, Stuttle, of Lew-Lin Farm based in central New York State in the Finger Lakes region, a Dairy of Distinc tion, began grazing about five years ago. The family includes Lewis’ son, Steven; herdsman Gordie Morgan; Lewis’ wife, Linda; and some part time help. They have a herd that is lOOper cent registered Holstein with 190 cows and 130 head of young stock.

The previous com fields were seeded to (Hchardgrass and Ladino clover. The Graze N.Y. Participating Farm now has 110 acres for the milking herd. In addition to the new seeding, the farm also added 500-800 pounds of high calcium limestone to all the paddocks. He also applies about SO units to the acre of ammonium nitrate in the spring. The cows arc placed out early— about April 20-25. Some can be placed out even earlier and do quite well, he noted. Stuttle noted that paddocks are mowed in May and June to prevent the growth Cram getting ahead of the cows. They are mowed with a 12-foot disebine and winnowed and chopped for haylage. The grass is kept at 8-10 inches maxi mum height so it is highly palat able and less feed is wasted by trampling. After four years, he noted, the herd milking average is at 21,000 pounds on SO percent less TMR fed during the grazing season, with less labor. The high average of milk is 72 pounds. Stuttle uses a 3/4-inch water line to all die paddocks. Fences are simple polywire on posts. Paddocks are rotated every 10-14 days in the spring. A simple com meal supplement is added to the diet In the past, milking used to be from a double-4 milking parlor (eight units). Now, they built a new parlor within the existing one and are up to a double-8 with 16 units milking twice a day, at 2 a.m. and 2 p.m. Taking the cows off the fields on hot, humid days at 2 p.m. helps the cows stay healthy. Also, providing water lines to troughs in the paddocks is working to improve milk yield. Stuttle noted that the cows “like to drink out of the troughs better than in the bom.” Stuttle also explained some renovations done to the laneways. Where at one time they were mud- r erence In Grantville dy and unmanageable, with “six to eight inches of slop,” the Stuttles dug the lanes out, put in a textile fabric and gravel, 6 inches of limestone dust, and smoothed them out Also, the farm makes use of a mobile grazing unit for the calves, raised in hutches. In the units, the young stock gradually get adjusted to feeding off the land. The use of grazing has worked well for neighbors. An electric fence was installed and the cows are content to harvest their own feed. Also, the neighbors like it because no more manure slurry is going on the fields.

ANDY ANDREWS Lancaster Fanning Staff GRANTVILLE (Dauphin Co.) Several award-winning forage and grazing supporters were hon ored for their work in promoting forages and grazing in the slate Wednesday evening here at the 1998 Pennsylvania Grazing and Forage Conference at the Holiday Inn. The Outstanding Pasture Pro ducer Award was presented to Jim my Gamer, Mjlntrose, Susquehan na County. Gamer has been intensively grazing his 70 dairy cows on 35 acres for nearly seven years. He has been actively involved in the Chesapeake Bay Program and the use of grazing to meet the program goals. ‘This accomplishment speaks for itself in highlighting Jimmy’s grazing management skills,” noted Dr. Marvin Hall, extension forage specialist Penn State. “Mr. Gamer is always willing and ready to share his grazing experiences and knowledge with others.” Gamer has hosted numerous field days and tours at his farm. These have included visiting far mers from as close as his neighbors to as far away as Russia. Dick Kauffman, Pennsylvania Forage and Grassland Council, a co-sponsor of the event presented the award to Gamer.

Kopczyk, Clym cr, manager of the Indiana County Conservation District Kopczyk has been active in pro viding opportunities for the resi dents of Indiana County to learn about uses of forages and grazing management “Louis tries to emphasize the role forages can play in proper conservation practices.” said Mar vin Hall. Penn State extension for age specialist “Although Louis discusses grazing management with many landowners on a one to-one basis, these educational opportunities arc provided primar ily by organizing and conducting field days and pasture manage ment meetings on farms around the county.” These field days and meetings arc supplemented with presenta tions on a variety of related topics presented by fanners, businesses, lending agencies, and government agencies. Hall noted, “His involvement of many diverse groups and organiza tions into these on-farm meetings stimulates understanding and bet ter cooperation.” Kopczyk also obtained a grant and produced a fact sheet on vari ous methods of supplying water to grazing livestock.
