Dairy Management. 



Whilst these analyses have been in the course of preparation, 

 with the view of being inserted in the Society's Journal, another 

 month has elapsed, during which I have proceeded with my 

 observations on dairy produce. On the 12tli of March I pur- 

 chased Mr. Smith's cow (see p. 153) for 12/. 10.?., being more than 

 her market value, for the purpose of trying her on my food ; her 

 yield of milk had then diminished to 8 quarts per day. On 

 the 31st of March, four weeks from the former weighing, and 

 nineteen days after being treated with my food, her yield of milk 

 had increased to 9^ quarts per day, and her weight to 8 cwt. 1 qr., 

 being 28 lbs. increase. 



Mr. Pawson's cow, which was continued on the same food, 

 viz., meadow-hay ad libitum, and a more limited supply of tur- 

 nips, reduced her yield of milk to less than 5 quarts per day, 

 without alteration in her weight. 



My cow first ])laced on trial with those of Mr. Smith and Mr. 

 Pawson, gave a yield of milk of 12 quarts per day, and gained 

 28 lbs. in the four weeks, her weight on the 31st of March being 

 10 cwt. 2 qrs. 



The weight and the yield of milk of the six, on the olst of 

 March, were — 



On referring to the previous weighing, there was little or no 

 gain from Feb. 4:th to March 4th5 the cows being at that time in 

 a somewhat more relaxed state. During March they wholly 

 regained their consistency. The gain shown in the weighing, 

 March 31, by the six cows, appears therefore unusually great. 

 It should however be computed as made during the eight weeks, 

 from Feb. 4th to March 31st, being with an average yield of 

 nearly 12 quarts (11"66) per day each, at the rate of S^lbs. each' 

 per week on the average. 



No. 11, it will be observed, is stated as giving more milk on 

 the 31st than on the 4th of March. It occasionally happens that 

 cows drop their yield of milk for a day or two, and then regain 

 it, especially when in use. The whole of these six cows were 

 kept free from calf till February, when Nos. 2 and 4 were sent 

 to the bull. I had some hesitation in regard to No. 4, from her
