■^2 FEEDING AND FATTENING. 



organs, such as the heart, aorta, lungs, windpipe, liver, gall- 

 bladder and contents; they also are proportionately equal so far 

 .as blood is concerned. 



As sheep mature and fatten, the internal offal parts increase 

 in actual weight, but decrease in proportion to the weight of the 

 animal. The loose fat alone of the internal offal parts in- 

 creases in actual weight in proportion to the weight of the body. 

 As sheep mature and fatten the total "offal" increases in actual 

 weight but diminishes in proportion to the weight of the body. 



Fattened sheep (shorn) should yield about 58 per cent. 

 <3arcass in fatted live weight; excessively fat sheep may yield 

 64 per cent, or more. "When the fattening food of sheep 

 contains less than about five parts of non-nitrogenous to one of 

 nitrogenous compounds, the proportion of gross increase for a 

 given amount of dry substance of the food, will not increase with 

 the increased proportion of nitrogenous compounds, whilst the 

 proportion of the carcass to the live weight will be somewhat 

 less, the carcass being more fleshy and containing less fat. 

 Sheep should '=tore up about ten parts of fat for every 100 parts 

 ■of non-nitrogenous substance consiimed. Sheep on a mixed, 

 fattening diet should give about nine parts dry increase, made 

 up of about eight parts fat, eight-tenths to nine-tenths of a part 

 nitrogenous substance, and about one-fifth of a part mineral 

 matter for 100 parts dry substance consumed, demonstrating 

 that nearly ninety parts of the consumed dry substance are ex- 

 pired, perspired, or voided from the system. The stomachs and 

 their contents constitute about seven and one-half per cent, of 

 the entire weight of the body; the intestines and other contents 

 amounting to about three and one-half per cent. 



Taking collectively the stomachs, small and large intestines 

 and their respective contents, we find that the entire bodies of 

 sheep yield an average of rather more than eleven per cent.
