Página 157 - ... yields would be much increased if not actually doubled. It does follow, also, that well drained lands in our State are not supplied naturally with as much water as most crops on them are capable of utilizing, and hence, that all methods of tillage which are wasteful of soil moisture, detract so much from the yields per acre. What we call good average yields per, acre are determined in a large measure by the amount of water which is available to the crop during its growing season, and what we...
Página 127 - Every precaution should be taken to have the sample represent as nearly as possible the whole lot of milk from which it is taken. Milk fresh from the cow, while still warm and before the cream has separated in a layer, may be thoroughly mixed by pouring three or four times from one vessel to another. Samples taken at once from milk mixed in this way are the most satisfactory of any.
Página 288 - It, with other things, forms protein, — the flesh forming feed, the material required for building up the tissues of the body, and for maintaining these under the wear caused by the vital functions.
Página 137 - Although it is quite generally admitted that the quality as well as the quantity of milk delivered should be considered in making dividends in factories where milk is pooled, many who recognize the justice of the relative value plan hesitate to adopt it on account of the labor and expense involved in making daily tests from each patron's milk. The best plan yet proposed for reducing the expense of the necessary test is that first described by Prof.
Página 148 - Delay in setting may cause a considerable loss with the milk from some herds and scarcely any with that of others. To avoid the possibility of such loss it is recommended that milk be set as soon as possible after milking. 4. Deep setting without ice under the most favorable conditions results in considerable loss, and where the water used is not lower than 50° F. the loss is excessive, reaching in some cases as much as 25 per cent, of the total fat in the milk. 5. The centrifugal system of separating...
Página 134 - The process, however, must be modified slightly from that used with milk, as the amount of fat in cream is so large that it cannot be measured in the ordinary test bottle, if the usual quantity is taken for the test, besides a much greater error results from the cream which adheres to the pipette than with milk. Both of these difficulties may be overcome by taking two or three...
Página 134 - CREAM. The chief difficulty in testing cream lies in the sampling. Cream that is sour, or that has been exposed to air until the surface has dried, cannot be accurately sampled. The same is true of centrifugal cream that is badly frothed. Sweet cream, from Cooley cans, that is not too thick to flow readily from the pipette may be tested with satisfactory results. The process, however, must be modified slightly from that used with...
Página 132 - Measuring the Fat. The fat when measured should be warm enough to flow readily, so that the line between the acid liquid and the column of fat will quickly assume a horizontal position when the bottle is removed from the machine. Any temperature between 110° F.
Página 131 - ... the water directly into the bottles without removing them from the wheel. The flow of water can be perfectly controlled by a pinch-cock upon the rubber tube. If only a few tests are to be made, the bottles may be easily filled with a pipette, or by pouring from a graduate. The cover should then be replaced and the machine turned...
