300 Agricultural Chemistry — Sheep- Feeding and Manure, 



The barley used in the experiments as such, and that which 

 was malted, were both of the same stock and quality ; the weight 

 of the malt produced was, exclusive of screened and kiln-dust, only 

 about four- fifths of that of the barley operated upon, so that as the 

 weekly allowance of barley was 7 lbs. per sheep, that of malt 

 would have been little more than 5J lbs., instead of 6 lbs. 9 oz., 

 as were actually consumed, if so much only were to be given as 

 was the produce of the amount of barley with which it was to 

 compare. Nearly one-half of the loss of weight sustained in the 

 conversion of the barley into malt was, however, only water, 

 and a portion of the remainder consisted of the "dust,'' which, if 

 malting were adopted to any extent for feeding purposes, would 

 certainly not be separated from the malt; and this, as we shall 

 afterwards see in discussing other experiments with barley and 

 malt, is a point of some importance. Weight for weight, how- 

 ever, the malt is seen to be about 6 per cent, richer than the 

 barley in dry-organic-matter, and to be equal to it in mineral 

 matter and in nitrogen ; and it will be found that the quantities 

 consumed of the two foods were in fact almost identical, so far as 

 above-named constituents are concerned. 



The following Table brings to view the total amount of food 

 consumed in the pens during the entire period of the experi- 

 ment — the total increase produced, and the amount of some of 

 the more important constituents contained in the food, these being 

 calculated from the Table of Analyses last given.
