Harvest it would then be possible in each test to use single pens and evaluate more stock at one time without worrying about the accuracy of the test due to variations in hous ing. Tests to measure any dif ferences iji growth rate and feed conversion due to locat ion and to evaluate separate and mterming ed rearing of broiler stock were conducted as part of the Southern Reg ional Poultry Breeding Pro ject. Each of 10 commercial broiler stock breeders pro vided enough eggs to supply 800 chicks a total of 8,000 Chicks from each source we re divided into 4 groups of 100 males and 100 females each Three of these groups were reared intermingled with a similar number of chickens from each of the other 9 sources Two identi cal houses of 20 pens each were used Feed, water space and equipment were kept identical in all pens. + •v * * Dutch tradition, dot phis pic ' on the Mast farm, in Penn <rld". the Pennsylvania Dutch Pa., is blessed by good 'es for its devout, hard- itly rolling land yields as [uality potatoes per acre. aul, put 65 to 100 acres <ast year, something new 'maneb) fungicide spray to guard against potato came assurance that this > & I - 3 DITHANE M-22 .. . now 80% maneb from your partner in crop protection Dithane is a trademark, Reg.

Dithane M-22 helped bring in his best crop ever... despite weather conditions which favored blight. And what’s more, he says Dithane M-22 appears to produce more uniform sized tubers. Bulk body weights by sex and source were taken at 8 weeks of age and individual body weights at 9 weeks. Fe ed consumption was record ed at 8 and 9 weeks of age. Mortality records were kept for all groups. At 8 weeks, intermingled birds weighed slightly more than those reared separately. But at 9 weeks, the advant age was slightly in favor of birds reared separately. The weight disadvantage for the mixed group may have been due to social tension, which becomes noticeable through bossiness and pecking in males at about 8 weeks of age. Tensions would normal ly be greater when birds from several sources are reared together. When body weigh data for separately reared broilers was analyzed, substantial differences for source and sex showed up, but no real difference could be traced to location At 9 weeks, mean ingful differences ' in body weight could be traced fo in teraction of location and source, and highly meaning ful differences were traced to the interaction of location, source, and sex This indi cates that broilers from the same source will perform differently in some locations than in others. Even birds of the same sex from the same sources will perform differ ently in different locations. Differences were found in feed conversion due to source of the broilers, none due to location And this was true Jacob K.

Saturday, April 16, 1960—9 Farm Women No. 7 Hear Miss Kirstein Miss Nita Kirstein, an ex change student from Ger many, gave an interesting and informative talk about the German school system at the April 9 meeting of the Society of Farm Women No. 7. Hostess was Mrs. Samuel Wenger, of Leaman Place, While Mrs. Milton Esben shade was co hostess. Devotions were in charge of Miss Sally Wenger and roll call was answered by members telling an “Old Fashioned Remedy”. even though all the stock tested was from commercial broiler stock breeders and did not differ as much in growth rate as would be ex pected if non-commercial or dual purpose stock had been included The scientists concluded that under their conditions, location or pen effects aren’t important if chicks «from a given source are reared sep arately and if care is taken to maintain uniform housing conditions. But location ef fects must be considered when birds are intermingled. Thus, not only is separate rearing advantageous from a standpoint of eliminating lo cation effects, it’s also pre fer ab’e where feed conver sion data is needed. Such da ta can’t be obtained with in termingled rearing. The society voted a con tribution of $lO.OO to the Crippled Children’s Fund and a collection totaling $l7, was taken for the Cancer So ciety Fund. The next meeting, a food sale with donations being re ceived for Christ’s Home will be held at the home of Mrs. Clyde Benedict in Kin zers on May 9.
