Swine breeders have long recognized the value of Pratts Hog Tonic as a disease preventive and fattener. Progressive breeders now consider it a necessity in profitable hog raising.
If a second litter is wanted during a year the sows should be put to the boar during the first heat after weaning. Many breeders do not like to pass periods of heat for fear that the sows may become "shy," and there is little reason why a sow should not have two litters a year. In any case, the sows should be carried on comparatively light feed until time to breed again, gaining a little in weight; and their treatment after breeding should be as already detailed for pregnant sows.
When the boar arrives at the farm he should be dipped in a solution of Pratts Dip and Disinfectant, as a matter of ordinary precaution against the introduction of vermin. As an additional precaution, a quarantine pen should be ready for him, especially if epizootics are prevalent. His feed before change of owners should be known, and either adhered to or changed gradually to suit the new conditions. If he has come from a long distance it will be well to feed lightly until he is well acclimated.
TAMWORTH PIG
Breeders generally advocate the practice of keeping a boar to himself during the entire year—out of sight and hearing of the sows. However, a boar is often allowed to run with the sows after they are safe in pig; but during the breeding season it is by far the best policy to keep him by himself, admitting a sow to his yard for mating, and allowing but one service. The litters will generally be larger and the pigs stronger.
The boar should not serve more than two sows daily, preferably one in the morning and one in the afternoon, and can serve 50 to 60 in a season without difficulty.
In order to keep the boar in vigorous physical condition, he should be given Pratts Hog Tonic regularly. The beneficial results will be seen in the way of larger litters and stronger pigs.
The greatest drawback to the hog industry which breeders in this country have to contend against is found in the losses which may be experienced through the infestation of the animals, especially young pigs, by parasites, through outbreaks of hog cholera or swine plague, or through the contraction of tuberculosis.
In dealing with the diseases of hogs, preventive measures must be most relied upon. The animals must be given dry and well-ventilated quarters, which must be kept clean. Contrary to common belief, hogs have some habits which raise them above other domestic animals from the standpoint of cleanliness. For example, unless compelled to do so, a hog will not sleep in its own filth. If part of the floor of the pen is raised and kept well bedded with straw, while the rest is not, all excrement will be left on the unbedded portion of the floor, and the bed itself will be always clean.
