96— T, an raster Farming, Saturday, April 3,1971 Leghorn Fertility and Hatchability Are Good On Sloping Wire Floors, Research Indicates Egg production by pullets on the sloping wue floor has been excellent since the concept was initiated in 1963 Perfoimance of pullets re ported by Biessler and Maw at the 13th World’s Poultry Con giess in 1966 showed egg pro duction of 253 eggs per pullet housed with pullets allowed 0 66 square foot floor space per bud Results on commeicial poultry farms have given simi lar results Piehminary trials to obtain fertility and hatchability m foimation with leghorn breed ers on the sloping wire floor system weie begun in 1966 Four hundred leghorn fe males which had been in pro duction foi eight months were mated with 18-month-old males (only ones available foi this pielimmary test) at a latio of one male to fifteen females, in 24 feet by 24 feet summer lay ing shelters A flom space allowance of 066 square foot pei bud was allowed Another group of 400, 26- week-old leghorn females was rhoused m a similar shelter .These females also were mated with 18-month old males at a latio of 1 to 15 An excellent level of fertili ty was achieved for the period from August 1, 1966, to Novem ber 7, 1966, and indicated the feasibility of high density hous ing of leghorn breeders on the sloping wire floor from the .standpoint of fertility HumuEioiis SIMPLEY BETTER FARM MACHINERY MILLER’S REPAIRS 8 Miles East of Lancaster R D 1, Bird-in-Hand, Pa ' Phone 717-656-7926 This research repoit by the Penn State Umveisity departments of poultry science and veterinary science shows that poultry breeding as well as volume of egg production can be successful with pullets in dense housing conditions using the modern A-frame or V-frame sloping wne floor The report was prepared jointly by G 0 Bressler, T W Burr, T A. Carter and R F Gentry of Penn State On February 6, 1967, an ex periment on a larger scale was begun using two 30 feet by 100 feet laying houses One flock of 2988 leghorn females, 22 weeks old, was housed on the A-frame sloping wu e floor in House 100, allowing 062 square foot floor space per bird One-hundred eighty males, a few weeks younger than the females, were added to this flock on April 18 Approximately the same number of females as in House 100 were placed in the other house (House 99) which was divided into two separate pens by a central egg aisle One pen (99A) had 1478 females; the ■other pen (998) had 1488 fe males Floor space allowance was 075 square foot per bird Eighty-seven males were added to this flock on April 18 No males were added to Pen 998 On May 5, the first cheek was made on egg fertility, and it was found that 95 per cent were fertile in House 100 and 98 per cent in Pen 99A. No check was made on hatchabihty with this first egg sampling Subsequent samplings of 100 eggs from each pen showed excellent fertility and hatch ability in both houses up to July 14, when this portion of the experiment was concluded On July 17, a single flock was established in House 99 by com bining the birds from House 100 with those in House 99 The center egg aisle was eliminated and nests placed at the top of the slope along the outside wall The single flock consisted of 4677 females and 290 males housed at 0 44 square foot per bird Samplings of 100 eggs were made for the July to December period to check fertility and hatchability As will be noted in Table 3, excellent fertility and hatchability continued through out this period and up to the (Continued on Page 28) ARE YOU READY FOR IMO-PLOWI PLANTINCJI?

Is a standard 16% ration enough, too much, too little? Well let’s take a look. Leading authorities say a cow giving 50 lbs. of 4% milk and weighing 1400 lbs. needs 3.05 lbs. of digestible proteirp If you were to feed her 10 lbs. of stemmy al falfa hay and 30 lbs. of mature corn silage, only 21 lbs. of a 9% digestible protein ration would be needed. Could it be that you are feeding too much protein? Paying for something you don’t need? We would be glad to review your feeding program at no obligation to you. Call your Pioneer Man: S ELMER M.
