scab control in our test plots in Dur- 

 ham. It serves a useful purpose, 

 however, for rust control on rust- 

 susceptible varieties such as Wealthy 

 and Winter Banana. 



In general, the eradicant sprays 

 mentioned will give more satisfact- 

 ory scab control than sulfur if thev 



are applied three or four times in 

 the pre-cover sprays. Their use as 

 single-shot sprays to eradicate scab is 

 not recommended. These materials 

 are compatible with nearly all the 

 common insecticides now in use.

Is Pellet Feeding More Efficient 

 ihan Mash Feeding? Mash feeding 

 has been compared with pellet feed- 

 ing for growing pullets from one day 

 to 20 weeks of age. A third group 

 was fed pellets without hoppers after 

 they were three weeks old. At 12 

 w^eeks of age, grain was introduced 

 into the ration of all pens and fed 

 in the litter. The pen-fed pullets in 

 hoppers became infected with coc- 

 cidiosis at about nine weeks of age. 

 This caused about 10 per cent addi- 

 tional mortality. The results, thre- 

 fore, are only indicative of the differ- 

 ences that may exist. 



In view of the coccidiosis condi- 

 tion it would appear that pellet feed- 

 ing is at least as efficient as mash 

 feeding and perhaps may have a 

 slight advantage. In the pellet-fed 

 groups considerable difficulty was ex- 

 perienced with feather picking but 

 there was little actual loss from can- 

 nibalism. Litter conditions were less 

 satisfactory in the pellet-fed pens 

 and, surprisingly, were least satis- 

 factory in the pen fed pellets in the 

 litter.

Should Replacement Stock Be 

 Raised on High Energy Feed? 

 Three pens of chicks were fed to 12 

 weeks of age to determine the rela- 

 tive merits of high-energy and regu- 

 lar mash feeds for growing broilers. 

 The high-energy feed was definitely 

 superior in feed efficiency and re- 

 turned more money over feed cost. 

 The regular mash feed gave a feed 

 efficiency of 3.71 pounds of feed per 

 pound of gain while the two groups 

 fed high-energy feed gave figures of 

 3.00 and 3.05. Income over feed 

 cost per thousand broilers raised 

 amounted to S448 for the regular 

 mash feed and $574 for the high- 

 energy feed. Mortality was low and 

 varied by less than II/2 per cent. 



At 12 weeks, males were removed 

 and the pullets continued until they 

 were 20 weeks of age. Also, at this 

 time, one pen which had received 

 high-energy feed was changed to the 

 regular growing mash. Grain was 

 introduced into the ration of each 

 pen and was fed in the litter. 



At the end of 12 weeks the birds 

 which received the high-energy feed 

 averaged 0.4 pounds heavier and had
