ANIMAL PRODUCTION. 483 



"Swedes grown on a good soil in East Lothian i)rov('<l not quite equal to swedesof 

 the same variety grown with the same maiuire on an inferior soil at Cockle Park; 

 but the latter were ([uite up to the average quality of the district, whereas the former 

 were not. 



"Of four (jnalities of clover and rye-grass hay tested, hay grown with 1\ cwt. 

 nitrate of soda, 7 cwt. of slag, and 4 cwt. of kainit per acre proved inferior to a 

 sample grown with slag and kainit only, and also to hay grown with | cwt. and If 

 cwr. of sulphate of ammonia with slag and kainit. In this particular case the 

 chemical and hotanical analyses of the hay indicate that the inferiority was (hie to 

 overripeness. 



"Twenty sheep fed under cover left 4| cts. yiev head per week more for their keep 

 than 20 sinular animals fed outside. 



"When slieep were fed on a diet consisting chiefiy of swedes it was found that 69 

 per cent of the live-weight increase in passing from a ' store' to a moderately fat con- 

 dition was carcass. When sheep were fed on a limited ration of swedes and a full 

 supply of hay 77 per cent of the live-weight increase was mutton. 



"The feeder who fattens cattle under cover appreciates the swede. At Cockle Park 

 it was found that f(jr sheep fed under cover the swede is a valuable food. Sheep fed 

 in the house for a period of 35 days were allowed as many swedes as they would 

 eat; they consumed alwut 15 lbs. per head per day; they gained (5.25 lbs. per head 

 upon this <liet, although it contained less nutriment than is usually assumed to be 

 necessary for maintenance. Twenty similar sheep fed in the same house and for 

 the same j)eriod were allowed 8 lbs swedes per day and as much seeds hay as they 

 would eat; they consumed about If lbs. per head of the latter; they gained only 1.64 

 lbs. per head in 35 days, although the diet from a chemical standpoint was more 

 liberal than the other. This result is explained by the fact that it takes more 

 digestible food to supply the animal's needs when the food is presented in a form 

 difhcult to digest — as in hay — than when in a form easy to digest — as in swedes." 



The improvement of pasture as tested by the effects on sheep, W. So.mek- 

 viLLE (Jh-pl. A<jr. < '(uiihridge Uiiir. Rpt. ]901, pp. 9-16) .—The value of different 

 fertilizers for pasture grasses was tested by grazing sheep on plats manureil in differ- 

 ent ways. The tests were made in Essex, Camliridgeshire, Norfolk, and Northamp- 

 ton. In the experiments at CamV)ridgeshire, plat 1 was not manured but the sheep 

 were fed daily 0.86 11). linseed cake per head. Basic slag was used on plats 2 and 

 4, and superphosphate on plat 5, while plat 3 was unmanured. A botanical analysis 

 of the hay from the different plats is given. The principal conclusions follow: 



"The live- weight gain, per acre and per sheep, was distinctly greater on the 3 

 manured plats (Nos. 2, 4, 5) than was the case on plat 1, where the sheep got daily 

 considerably more than f lb. per head of linseed cake. A similar result was got in 

 Northumberland in 1898. 



"Plat 2, receiving J ton of basic slag, carrie<l nearly 2 sheep more than plat 4, 

 which was dressed with half the (juantity of slag, t)ut the gain per head per week in 

 the latter case was somewhat higher. 



"When equal amounts of phosphoric acid were used in the 2 forms of Imsic slag 

 and superphosphate, the latter produced the larger live-weight gain. A similar 

 result was got in the first year pf the Northumberland experiments. 



"The unmanured plat gave decidedly the lowest yield of animal increase." 



The other tests are very briefly reported, as they are not ended.
