6. Acceptability trials of a limited number of hays determined 

 using mature wethers indicated that the order of acceptability followed 

 that of the digestibility and net energy content. Of the three hays fed, 

 June 1 harvest Commercial, June 30 Commercial and June 30 Essex all 

 grown at Groveton under 100 lb. nitrogen per acre, the intakes per 100 

 lb. live weight were 0.96, 0.62 and 0.62 lb., respectively.

Table 6 shows the statistical analysis of the data. 



1. The effect of date of cutting on the digestibility of the protein, 

 total digestible nutrients, digestible energy and net energy was signifi- 

 cant. 



2. Rate of nitrogen fertilization affected the digestibility of the 

 protein, significantly but had no effect on the total digestible nutrients, 

 digestible energy or net energy of the forage.
