2. =Feeding continued.= Just as we use lumber, brick, cement, shingles, nails, etc. in the proper form and proportion in building a house, so must we use milk, corn, oats, grass or other feeds in the building of the body of the hog or any other animal. Each feed is made up of different food nutrients, and each food nutrient serves a definite purpose in the body. Some of the food nutrients are used in the animal body to make bone, others for fat, and still others for the manufacture of active muscular tissue. Development will be incomplete if any class of food material is neglected; hence the necessity of a balanced ration. Follow carefully the feeding standards and rations suggested for November and December. 3. =Keeping the pigs healthy.= It is much easier to keep pigs healthy than it is to cure sick ones. Clean, dry quarters, proper feed, plenty of sunlight and ventilation, and disinfection of houses will help to keep pigs healthy. Go over your pig pen this month, and as often thereafter as is necessary, and clean out all filth from cracks and corners, floors and feeding troughs. Apply the following disinfectant: 5 parts crude carbolic acid in 100 parts water Once a year the pig house should be whitewashed. (See discussion in Part III.) If possible, supply “hog wallows and dips” for your pigs. (See Part III.) MARCH AND APRIL 1. =Starting the pig project at this time.= If it is desired to start the pig project at this time instead of in September, the club may be organized, a pure-bred gilt to farrow in April purchased by each member of the club, and the work started as suggested for September and October. 2. =See the September and October calendar.= In all essential points the members of the class beginning the pig project at this time should follow every detail outlined for September and October. 3. =The October pigs.= Continue the feeding rations of the October pigs as suggested for other months, according to weights and gains, and make larger use of the pasture as a supplement as the spring advances. Alfalfa pasture has proven by many tests to be one of the best for growing pigs. After the first season for alfalfa, an acre should pasture two sows and their litters throughout the season. The corn rations may be cut one-half with alfalfa as a pasture. “Pigs in clover” are contented and happy. An acre of good clover should pasture one sow and her litter. A Missouri bulletin recommends feeding shoats about a pound of corn per head per day when on good clover pasture. 4. =The second litter.= If the second litter of pigs for the sow for the year is farrowed in April, as was recommended at the beginning of this project, quarters separate from the October pigs should be provided for them for at least eight weeks, or until the second litter is weaned. See directions for the care and management of the sow and pigs as given for September and October.
