C2-Lancaster Faming, Saturday, April 15, 1995 IS CHOLESTEROL IMPORTANT FOR IMMUNITY? Dr. Magdi Mashaly Associate Professor Poultry Science Cort Bucher'" And Ahmed Gehad* The misconception about the relationship between cholesterol in the diet and human health definite ly has had an adverse effect on egg consumption in the U.S. This, in turn, results in a reduction in egg prices and lower profitability for poultry producers. Jackpot Show July 29 YORK (York Co.) —The Pennsylva nia Livestock Associa tion is sponsoring a Jackpot Show on July 29 for steers, barrows, and lambs in conjunc tion with the Keystone National Rib Cookoff and Music FesL The Rib Cookoff will run from July 27-30 at the York Fairgrounds and is a fund-raiser to support the Keystone Interna tional Livestock Exposition. All youth ages 8-19 are reminded to consid er this event when pur chasing project animals this spring. The jackpot show is only for steers or barrows, but ewe lambs and wethers are eligible in the sheep division of this market animal event. Jackpots for the three shows total a minimum of $1,600. The champ ion steer will receive at least $5OO, the champ ion barrow $250, and the champion lamb $250. There are guaran teed minimum pre miums for the top five placings in each class. A supreme champion of all three species will be selected. Entry fees are $2O/steer and $lO/barrow or lamb if preregistered by July 10. Each exhibitor will receive two admissions to the Rib Cookoff and Music Fest. Admission to the Rib Cookoff on Saturday includes country music entertainer Ken Mel lons, featuring his hit singles, “Juke Box Junky” and “Working For The Weekend.” For more information and registration forms for the Rib Cookoff It is important to know that blood cholesterol in humans is not only derived from dietary sources, but also is naturally synthesized in the body. The amount synthesized in the body depends on die amount consumed in the diet. When low levels are consumed, the body may be required to syn thesize large quantities to meet body needs. The reason the body synthesizes cholesterol is because of its importance in different vital physiological functions. For example, cholesterol is a precursor of different important steroid hor mones such as progesterone, estro- KID HUM t* * New Della-Flpw™ Milk Filters from Alfa Laval Agri are designed to perform better than any other filter on the market today. Seventy-five percent of the dairymen who tested the New Della- Flow filters believed they retained as much sediment as the top-rated orange-stripe filters currently on the market and a full ' 25% believed New Della-Flow filters retained more. This superior filtration is due to a special fabric weave that exceeds burst strength needs by almost 108% and more easily traps small particles. And the more sediment that’s retained, the higher the quality of milk and the greater the potential for profits. Kim INK The special fabric weave and sewn seam add up to a better value for you. Why 1 Because those features enable us to fit more of the New Della-Flow'“ Milk Filters into each box than the orange-stnpe and other glued-seam competitors. In fact, you’ll find 10% more filters in each New Della-Flow box for about the same price That’s a savings you can pocket immediately What’s more, the savings you’ll realize from the New Della-Flow filter’s better filtration and milk flow will just continue to add up. gen, and androgens which are important for reproduction func tions. Therefore, maintaining a certain level of circulating choles terol is essential for proper physio logical functions in the body. To emphasis this point, we con ducted an experiment using three genetic lines of mature male Japanese quail obtained from Dr. H. L. Maries, Southeastern Region al Laboratory, USDA. The first line was selected for high circulat ing levels of cholesterol, the sec ond was selected for low cholester ol levels, ai.d the third was unselected and served as a baseline. We used two dietary treatments with each line. One diet contained 2,900 keal/kg ME with 20 percent protein with .5 percent crystalline cholesterol added. The second (control) diet was similar to the first but without cholesterol added. Total cholesterol in the blood was measured in all birds. To mea sure the effect on immunity, the activity of lymphocytes were mea sured by determining the rate of BETTB ■im In long-term testing among dairymen, nearly 90% rated the New Della-Flow™ Milk Filter as excellent in terms of milk flow. This superior milk flow is achieved because of New Della-Flow filter’s special fabric design and a seam that’s sewn, rather than glued like the competition. The sewn seam not only makes the filter easier to install, it provides 4-10% more surface area for better milk flow. And better milk flow means faster milking and less wear and tear on valuable milking system components. I 1 BETTER am u i nr.

Lymphocytes arc the most important white blood cells in eliciting an immune response. We found that when we com bined results from all genetic lines, adding cholesterol to the diet increased blood cholesterol by 700 mg percent (from 250 mg percent to 950 mg percent). Furthermore, lymphocyte activity of the quail fed cholesterol was reduced when compared to control quail. This indicated that when cholesterol levels were extremely high, the immune response could be inhi- ELEABETHTOWN (Lancas ter Co.)

However, we also found that when cholesterol levels in the blood were reduced to 167 mg per cent in the low line, activity of lymphocytes were also inhibited when compared with the high line that had cholesterol level of 374 mg percent. These results confirm the notion that a certain level of blood choles terol is needed to maintain proper immune response.
