tion and every thirty days thereafter during their lactations these animals 

 were changed to the other feeding program. 



The remaining cows in the herd were divided into two similar groups 

 on the hasis of production, calving date, and age. One group was fed 

 dried citrus pulp at one feeding and an equal amount of the conventional 

 grain mixture at the other for one calendar year. The other group received 

 no citrus pulp during the same period. Records kept were similar to those 

 for the reversal animals. 



Results and Discussion 



The average daily milk production, 4 percent fat corrected, for the two 

 groups of reversal cows during the first six months of lactation is shown 

 in Figure 1. The average daily production for this period was 31.9 lb. on 

 grain and 31.5 lb. on citrus pulp. Analysis of the data showed that there 

 was no difference in milk production on the two rations. Milk production 

 values for the remainder of the animals in the herd were not suitable 

 for study because the data usually consisted of parts of two lactations. 

 There was no evidence of any effect of citrus pulp feeding on lactation, 

 however. 



When the monthly body condition ratings for those cows which received 

 one feed per day of dried citrus pulp for one year were compared with 

 those for the grain-fed animals, it was found that the difference was not 

 significant. Those animals which received citrus pulp appeared to be in 

 just as good condition as the other animals. 



Breeding efficiency as shown by a summary of conception rates for the 

 period of the experiment and for the previous year is given in Table 8. 

 A statistical analysis of these data indicated that the animals conceived 

 just as readily as during the previous year and that there was no difference 

 between those animals which received citrus pulp and those which did not.
