950 Summary of Agricultural Experiments, [feb., 



In 1909 and 1910 tests were made with (1) whey and a mix- 

 ture of equal parts barley meal and maize meal ; (2) same as 

 (1) with addition of cooked potatoes; (3) same as (1) with addition 

 of uncooked potatoes; (4) whey and a mixture of two parts barley 

 meal to one part rice meal ; (5) whey and a mixture of equal parts 

 barley meal and Paisley meal. 



On the average of these two last experiments whey, with a mixture 

 of equal parts barley and maize meal, gave the best results, both as 

 regards live weight increase and the balance remaining after paying 

 for food consumed; while the barley meal and Paisley meal mixture 

 proved better than the" barley meal and rice meal. Neither Lot 2 

 nor Lot 3 gave any return for the potatoes supplied. 



Pork Production with Forage Crops (Univ. of Missouri, Agric. Expt. 

 Sta.j Bull. 95). — This bulletin gives the results of experiments carried 

 out with the object of determining what forage crops are the most 

 suitable and economical for feeding pigs. In an introduction to the 

 report it is stated that with increased prices of grain and feeding 

 stuffs of all kinds, the greater use of cheap forage crops must be 

 looked to, to reduce the cost of producing pork. The forage crops 

 tried included maize and rye, lucerne, peas, soy beans, red clover, 

 blue grass, rape and oats. 



The general plan of the experiment was as follows : — The hogs used 

 were of early spring farrow, weighing at the commencement about 

 50 to 70 lb., live weight. Each forage was supplemented with grain, 

 in quantities sufficient to produce a standard and equal rate of gain, 

 the object aimed at being to have the animals from 125 lb. to 150 lb. 

 live weight, at the end of the experiment. The experiments were 

 carried out in the three summers 1908, 1909, and 19 10, with the fol- 

 lowing results : — 



Lucerne gave better returns than any other forage. The best 

 system of using it appeared to be to supplement it with 2 lb. of maize 

 per day for every 100 lb. live weight of the animal. In 1910 the total 

 gain per acre in live weight of pigs pastured on lucerne was 1,310 lb., 

 though, in addition to the lucerne, 4,022 lb. of maize was fed. 



Red clover ranked next to lucerne as a forage plant for pigs. It 

 did not feed so many per acre and also had a shorter forage season, 

 but it fitted better into the rotation systems. In 1910, the only year in 

 which it could be compared with lucerne, red clover produced an 

 increase in live weight of 1,050 lb. per acre, though, in addition to 

 the pasture, the pigs received 2,872 lb. of maize. 



The bulletin suggests that the following is the best system of 

 using the clover : — While the clover is growing rapidly about a 

 pound a head of grain per day should be given ; when in bloom 

 (and it should not be pastured so closely but that it will bloom) little 

 or no supplementary food need be given, as pigs are fond of clover . 

 heads, and will make satisfactory gain without grain. At other times 

 from 3 to 5 lb. of grain per head per day may be given. 



Rape did not give such good returns as clover and lucerne. The 

 best results were obtained when it was sown along with oats and 

 red clover, the latter being left to stand over till the following year. 



It was found difficult sometimes to get the pigs to eat rape when 

 first turned on to it.
