mplex is raised in Lancaster Co. '4B Q the pens in the gestation rooms. These woven floors allow manure to drop down into pits which are flushed out continuously. Middle Creek’s manure system is the first ot its kind to be installed in a farrowing operation in the East, noted Horst. The Lissco system incorporates an aerated lagoon with a solids separator. Manure collected in the pits is flushed to the separator where the solids are extracted and the waste water is piped out to the lagoon. The solids will be fed to beef cattle in a corporation member’s feedlot, according to Hofst who claims it "comes out like silage.” "The manure from the separator is 70 percent moisture. This manure either has to be dried or used within 40 horn's. We plan to feed it at 70 percent moisture and add nutrients and protein to the cattle’s diets,” he said, noting an analysis of ‘wastage’ measured 14 percent protein. l-,) The waste water tbat is stored in tbe lagoon will <be irrigated ouiu croptields once a/year. The rest ot the year, daily aeration ot the water is claimed to eliminate odor and balance the acids in the waste water, along with stabilizing the nitrogen and neutralizing bacteria. Betore waste water is sprayed onto the crops, it will be reused to tlusb the manure pits at the rate of 100,000 gallons a day. Horst claimed there is no problem with recycling disease along with the waste water, and the con tinuous flow of water through the pits means "no gas, no dust, and no odor.” The lagoon also is the 'catch basin’ tor excess tresh water that flows through the troughs and the pen wash-down water. This adds up to an additional 20,000 gallons ot water per day.

Adequate protection against brucellosis in cattle, a disease causing abortion and reduced milk production, can be produced with a substantially reduced dosage of Strain 19 vac cine, Science and Education Ad ministration research indicates.

Dorsey, and technicians Kathryn A. Meredith and Linda A. Garrett compared results with dosages of 10 million, 100 million, 1 billion, 10 billion, and the former standard rate of 90 billion bacteria. They vaccinated 106 beef hgifers as yearlings and 106 Angus-Hereford heifers as 4- to 6-mpnth-old calves. After vaccination, the heifers were tested for false positive reactions in diagnostic tests for brucellosis. False positive reac tions may cause vaccinated animals to be classified as possibly diseased, which may lead to their slaughter The intensity and duration of ■ false positive reactions were directly related to vaccine dosage levels, Deyoe says.

In heifers vaccinated as calves, only Id- and 90-billion dosages produced false positive reactions lasting as long as 12 weeks after vaccination, Deyoe says. All of the heifers vaccinated as calves tested negative when immunity was challenged at 15 months after .. vaccination. The heifers’ immunity to brucellosis was challenged by inoculating the heifers with virulent B, abortus bacteria. Levels of immunity produced by the various vaccine dosages dif fered according to the age of the heifers at vaccination, the researchers found. In yearling heifers, all vaccine dosages produced significant and indistinguishable levels of im munity. In heifers vaccinated as calves, higher dosages produced higher levels of immunity. The 90- billion and 10-bilhon dosages gave maximum immunity, the 1-bilhon and 100-million dosages gave adequate immunity, and the 10- million dosage produced noticeable but less than adequate immunity. Deyoe says that ideally, dif ferent dosages should be given to calves and to yearlings and other animals. Practical considerations may, however, dictate a com promise intermediate dosage for all ages. BUTLER AGRI-BUILDER Itate.
