Show Q. What can be done to prevent damp litter in the laying house? A. According to M. E. Jackson of of Kansas State College, proper ventilation will help keep the litter dry in the laying house. He says it is necessary to have a complete air change approximately every two minutes to remove moisture. There should be at least one square foot of open space in the front of the house to every 10 square feet of floor space. Poultrymen who have-trouble have-trouble with damp poultry houses should make necessary changes to get more air movement through the laying house. Q. Will it save grain to feed dairy cows roughage more than twice a day? A. Yes, says Lyle Jackson, Iowa State College extension dairyman. Cows will eat eight to ten hours a day if feed is kept before them, according accord-ing to Jackson, and he recommends feeding hay three or four times a day, or keeping the mangers full, and feeding silage three times a day. Q. Does it affect the size and health of rabbits to breed does 21 days after kindling? .A. Apparently not. For the past several years experiments have been under way at the Purina Research Rabbitry to determine how to get the most pounds of rabbit meat per doe per year, and the proper time to breed does after kindling to get the most young per year. These experiments ex-periments show that New Zealand does, which are bred the day their young are 21 days old, kindle and wean the most litters and a higher average number of young per doe per year. Furthermore, the size of the rabbits, their health and condition condi-tion has been as good as it was in the rabbits when the system was followed of breeding them when their young were 8 weeks old. Q. What causes hairless pigs? A. Hairless pigs show that there's a deficiency of iodine in the sow's body. Insufficient iodine may be the result of: 1. Too much calcium or fat in the diet which prevents iodine absorption into the sow's system. 2. Lack of iadine in the soil and, therefore, no iodine in the feed or water.
