PREVENTION OF ROUNDWORMS IN PIGS 5 



The udders particularly should be well washed with soap and water, 

 and the feet should not be neglected. If this precaution of cleaning 

 the skin of the sows is not taken they are likely to carry with them 

 into the farrowing pens a multitude of worm eggs and other disease 

 germs found in the soil of the hog yards, so that even with the first 

 few mouthfuls of milk the newborn pigs may swallow hundreds or 

 possibly thousands of worm eggs and germs of disease. It has been 

 found advantageous to oil the sow two or three days before farrowing 

 as a control measure for mange and lice infestation. This is accom- 

 plished by hand applications of crude petroleum or crank-case oil. 

 Further information on the control of swine parasites may be found 

 in Farmers' Bulletin 1085, Hog Lice and Hog Mange. 3 



After farrowing, the sow and pigs are not allowed out of the 

 farrowing pen until they are taken to pasture for which previous

Fig. 4. — Cleaning the farrowing pen.. This is a matter calling for a shovel, broom or 

 brush, plenty of hot water, soap and lye, and vigorous work 



arrangements have been made. The sow and her litter, in from a 

 few days to two weeks after farrowing, are moved to pasture by 

 means of a barnyard "Pullman" consisting of a double crate on 

 a sled which may be backed up to the door of the pen and hauled 

 away. (Fig. 5.) The lower compartment of the crate is for the 

 sow, the upper is for the pigs. 



Pastures 



A special pasture for the sows and young pigs is provided. This 

 should not be a permanent pasture which has been much used by 

 hogs and thereby more or less badly contaminated by their drop- 

 pings, but a field that has been under cultivation and sown at the
