Calf-rearing Experiment. 



Lot 3. — Gruel. 



As before, the four calves had whole milk for the first three 

 weeks (March 26 to April 15), 1 gall, per head daily on the 

 average. They were weighed on April 16, and thence received 

 their special food, the oatmeal and linseed being made up into 

 a gruel with water. For the first week the lot of four had 

 4^ gall, whole milk with 1^ gall, separated milk daily, and 

 ^ gall, daily of gruel. The whole milk was reduced gradually, 

 and the separated milk and gruel increased. After three weeks 

 they were taking 4 gall, daily of separated milk and 1^ to 

 2 gall, of gruel daily for the lot of four. During this period 

 one calf began to show signs of scouring, and. as it had eventu- 

 ally to be removed from the experiment, it is left out of account 

 in the final reckonings. The total food consumed in the nine 

 weeks by the four calves was : oatmeal 84 lb., linseed, 14 lb., 

 whole milk 57 gall., separated milk 224 gall. — cost 4^. 6s. 4(i., 

 being 2.s. A'lld. per calf per week, or, reckoning the three 

 weeks' preliminary feeding on whole milk, 6Z. 16s. 6d., being 

 2s. lOd. per calf per week. The live- weights were : —

^ Calf scouring. 



Leaving out the calf that was not well, this gives a gain of 

 225 lb. for thi-ee calves during the three weeks, being 8'33 lb. 

 gain per calf per week, each pound gain in live-weight costing 

 6'45d. 



Lot 4:.~Whole Milk. 



This lot were purchased a week later than the foregoing, so 

 that their preliminary feeding began on April 3. They were 

 weighed on April 23, and continued for the next 9 weeks on 

 whole milk, taking on the average a gallon each daily at first, 

 and then going up to 1^ gall, each after a fortnight's time. 

 In the 9 weeks they consumed, in all, 356 gall, of whole milk, 

 costing 101. 7s. Sd., being 5s. 9"22d., per calf per week, or, 

 with the preliminary feeding, 121. 17s. lOd., being 5s. 4*45c?. 

 per calf per week. The live-weights were : —
