Էջ 268 - Jersey citizen who is concerned in agriculture, whether farmer, manufacturer, or dealer, has the right to apply to the Station for any assistance that comes within its province to render, and the Station will respond to all applications as far as lies in its power.
Էջ 65 - The mixture should be strained through a sieve of 20 meshes to the inch in order to remove the coarse particles of lime, but all the sulphur should be worked through the strainer. The amount of water required to make the best mixture depends largely upon the lime. Some grades of lime respond quickly and take a large quantity of water, while others heat up slowly and are easily "drowned" if too much water is added at once.
Էջ 148 - In some years the selection was fortunate in getting nearly all the breeders from good (•/. e., "high production") genotypes or from good combinations of genes. In other years just the opposite thing happened ; the high layers chosen as breeders came from low genotypes or combinations of genes. The general upshot was that while the selection of high layers merely as such was systematic year after year the result attained in the general flock production was entirely haphazard and uncertain. This...
Էջ 158 - In the experiments during the past three years the attempt has been made to propagate separately lines of high, medium and low fecundity. In the course of this work it has been found that lines of high fecundity were nearly if not quite as likely to have originated with individuals of a low record of production as with those of a high record. Similarly, many low fecundity lines have originated with individuals which were themselves exceedingly high layers. Indeed one of the highest winter layers...
Էջ 65 - Place the lime in a barrel and pour on enough water (about 3 gallons to 20 pounds) to start it slaking and to keep the sulphur off the bottom of the barrel. Then add the sulphur, which...
Էջ 149 - I. age winter productions were 23.87 and 2.40 eggs, respectively ! Certainly it seems reasonable to conclude that the gametic constitutions involved in the breeding of 253 and 14 were quite different, though both these hens laid the same number of eggs. Again, take birds No. 386 and 911. One had a winter record of 55 and the other of 52 eggs. Yet their daughters' average winter productions were, respectively, 4.88 and 27.33 eSSsMany more instances of this kind could be brought forward.
