Feeding Dairy Cattle

MIost farmers realize that good dairy cows will produce more milk when properly fed than when fed scant rations. However, many dairy cows in Iowa receive rations that will not allow them even to approach a profitable level of production. There are several reasons why cows are underfed. The chief reason is that a majority of men, while they know that increased feed will result in more milk, arc not yet convinced that this increased yield will justify the feed cost. They believe that a low feed cost is the ultimate aim in profitable dairying. Economy and thrift in selecting rations are indispensible for profit; extravagance and wasteful expenditures for unnecessary feeds are to be avoided; yet such false economy as allows a cow little better than a starvation ration is deplorable. Successful dairymen had to learn the value of good feeding before they were able to succccd

Dairy Barns and Equipment

The efficient operation of a dairy farm necessitates good buildings. \u27!\u27his applies to the dwelling houses for the owner and workers, all buildings needed for housing the livestock, for storage of feed, and to care for the products of the farm. So far as the dairy cattle are concerned many reasons can be advanced for the provision of proper buildings, but they can be summed up in two words- sanitation and economy

A comparison of roughages for milk production

Altho dairy cows are especially adapted to the consumption of various roughages and tho they utilize more profitably than other livestock many such feeds which cannot be marketed directly, yet there is a marked difference in the values of roughages when considered from the standpoint of milk and butterfat production. That fact is emphasized in the results of the dairy feeding trials with Iowa’s standard roughages, corn silage, corn fodder and timothy and legume hays, reported in this bulletin. In the three tests, alfalfa was the legume hay used, tho clover could have been used in its place. Corn silage has a decided advantage over corn fodder in the ration, and its dry matter seems to be worth about again as much as that of the fodder. Alfalfa hay was shown to have 20 times greater feeding value than timothy hay

Milk Goats

Greater use is made of milk goats in many European countries than in the United States. Italy, France, Germany and some of the Balkan countries have from 20 to 75 percent as many milk goats as dairy cows. In the United States census of 1920 milk goats were classified with common American goats under the heading of goats not kept for fleece. As the number included in this classification was 6 percent as great as the number of dairy cows in this country, it is obvious that the relative number of strictly milk goats is small

Raising Dairy Calves

In the Corn Belt it costs approximately $100 to raise a heifer calf from birth to producing age. About three-fourths of this charge is for feed; the rest is for labor, housing and other items. The attitude that the raising of heifers is a too expensive practice is held by some dairymen with grade herds who are located in the denser dairy regions where whole milk is· the product sold and feed prices are usually high. Farmer-dairymen, who sell cream and have skim milk available, and breeders of purebreds generally do not question the advisability of raising heifers. Purebred heifers cost but little, if any, more to raise than grades and have about twice their value

Raising Dairy Calves

The average age at which the dairy cow In the United States either dies, Is butchered, becomes a non·breeder, or for some other reason ceases to be a producer, Is six years. To many this figure may appear low, for cows are sometimes productive at ten or twelve years and even at fifteen or sixteen years and older. These cases of exceptlonal longevity are notable and they appear to be numerous, but the number of cows which die previous to th~lr sixth year Is far greater. Studies of many herds, of both grades and purebreds, under all conditions, thruout the country, confirm the statement that the productive life of the average cow terminates when she 111 six years old. Dairy heifers become producers when two years old and thus their average production period continues for four years. There are In this country approximately 24,000,000 dairy cows; one-fourth, or 6,000,000, drop out of production each year and must he replaced. It Is safe to assume that 18,000,000 calves are born annually; probably one·half of them are bulls and from the remaining 9,000,000 heifer calves must come the two·year old heifers to replace the 6,000,000 discarded cows

The economy and efficiency of a milking machine

Industry has progressed considerably in substituting mechanical appliances for hand labor, thereby vastly reducing unit production costs. In more recent years agriculture has been making wider uses of mechanical equipment with the result that production has been increased, altho the proportion of agricultural laborers has markedly declined. Kinsman1 states that within the last 75 years a man\u27s ability as a field worker on the farm has been trebled. As the future of agriculture is studied it seems likely that the greatest opportunity for reducing production costs is to increase the output per man thru mechanical equipment. It is with a hope of lessening labor costs that mechanical milkers are now being installed on numerous dairy farms

Influence of environment and breeding in increasing dairy production-III

The constant growth of the dairy industry constitutes a notable phase in the history of American agriculture. That the industry will continue to grow is beyond question. The wider knowledge of the food value of dairy products, the increasing demands in America for intensive and economical production, to which demands dairying is especially adapted, and the more general recognition of . the financial possibilities that lie in dairy farming all attest the view that the greatest development of the industry is yet to be realized. Good dairy cows are indisputably the foundation upon which this development will depend and what is just as true, such development will be accompanied by a steadily increasing demand for these good cows
