Bulletin No. 135 - A Study In Annual Egg Production: Based On The Records Of A Flock Of Seven-Year-Old Hens And Their Progeny, E. D. Ball, Geo. Turpin, Byron Alder

UAES Bulletins

Experimental work in breeding for egg production was started with this flock of Single Comb White Leghorns in 1907. The flock of 1907 was hatched from eggs from a small flock that had been introduced into the plant two or three years before.

After two years' records of these flocks had been completed and studied it was found that nearly three-fourths of the first flock had made better records the second year than they did the first and that there was a great variation in the two years' records of individual hens. This raised the question of whether the first …

Bulletin No. 127 - Report Of The Richmond-Lewiston Cow Testing Association, W. E. Carroll

UAES Bulletins

The function of all domestic animals is to utilize the coarse rough reeds and transform them into something useful to mankind, either food, clothing, or energy. The animal thus acts as a concentrator for low grade ores, so to speak. The class of animals which will produce most human food, clothing, or energy for man from a given amount of feel--other cost being equal--is the most economical and the one which will remain longest with us as population becomes more dense and the question of food supply becomes keener.

Experiments have shown the dairy cow to be probably the most …

Bulletin No. 107 - Improvement Of Utah Horses, John T. Caine Iii, H. J. Frederick

UAES Bulletins

Horse breeding in Utah, with some exceptions, has been carried on in a hap-hazard manner, and unsound horses of doubtful breeding have been purchased at high prices and have proven of little value. Where good blood has been introduced the temporary improvement has been marked, but as this work has not been followed up with care, results have not been lasting.

In spite of bad breeding, however, the standard of Utah horses has been advancing so that in western markets they command high pries. The climate, soil, feed and general conditions throughout the state make it an ideal place for …

Bulletin No. 102 - Poultry Experiments, James Dryden

UAES Bulletins

There are many problems connected with the housing of poultry. Among them the question of egg fertility is one of the most important. We have begun investigations at this Station to learn if possible what kind or method of housing is most conducive to a high percentage of fertility in the eggs. It is a serious question with many poultrymen how to maintain the percentage of fertile eggs, and there have been cases where the poultryman has been driven out of the business because of inability to renew his flock. There is little doubt that the artificial methods, both in …

Bulletin No. 96 - Care Of Milk On The Farm And The Manufacture Of Butter And Cheese, R. W. Clark

UAES Bulletins

Dairying is one of the most profitable lines of agriculture in Utah. Ever since the establishment of the dairy industry in the State, the demand for Utah butter and cheese has been strong and prices have averaged good. A good article will always sell at top price; a poor article may sell at a good price when the demand is strong, but it will not sell at a good price, if at all, when the demand is weak. High prices are undesirable at any time if they create a tendency to put out a poor article. The success of any …

Bulletin No. 90 - Feeding Beet Molasses And Pulp To Sheep And Steers, Lewis A. Merrill, R. W. Clark

UAES Bulletins

Very few stockmen possess a knowledge of the value of beet pulp and beet molasses as animal food. Very little is known of the food value of molasses, but much information has accumulated, from time to time, concerning the value of pulp as stock food. The most authentic data at hand concerning the food value of pulp come from our experiment stations. To emphasize the value of pulp with the view to encourage small farmers to use it and thereby strengthen the live stock industry of the State, the results obtained by some of our experiment stations are given in …

Bulletin No. 82 - Feeding Beet Pulp To Steers And Sheep, R. W. Clark

UAES Bulletins

For the last two winters feeding experiments have been carried on by this Station to ascertain the value of beet pulp and beet molasses as food for sheep and steers. In a feeding test made with sheep two years ago, the results of which are reported in bulletin No. 78, sugar beet pulp and sugar beet molasses gave profitable returns. When lucern and pulp were fed, one pound of gain was made from 7.95 pounds of lucern and 17.86 pounds pulp. One hundred pounds of increase was made at a cost of $2.48 and pulp had a value of $1.86 …

Bulletin No. 94 - Summary Of Pig Feeding Experiments At The Utah Experiment Station From 1890 To 1902 With Deductions From The Same, F. B. Linfield

UAES Bulletins

The Utah Experiment Station has conducted a large number of feeding experiments with animals, the most extensive work in this direction being with hogs. Since the station was organized, over one hundred tests of various rations have been made and over three hundred hog;s have been fed. The results of these feeding tests are scattered through many hundred pages of reading matter in the station publications. As the continuation of these experiments fell upon the writer, it was decided to investigate thoroughly the work already done at the station and to tabulate the results for study. A summary of the …

Bulletin No. 67 - Poultry Experiments, James Dryden

UAES Bulletins

The results of the third year's work in egg production at this Station, together with the summing up of the results of the three years, are given herewith. The third year's work began Nov. 7,1898, and ended Nov. 1,1899. Some of the experiments originally planned have run the full period of three years. In addition to a continuation of the original work a set of feeding experiments was conducted during the third year. This latter work was made possible by the erection of an addition to the poultry house which doubled the experimental capacity of the building and made possible …

Bulletin No. 61 - Alfalfa Or Lucern: The Cutting Time. Its Feeding Value., Luther Foster, Lewis A. Merrill

UAES Bulletins

These experiments, as originally planed, had for their object the determination of the best time to cut alfalfa in order to secure the most profitable annual yield, its chemical composition, digestibility and the results of feeding trials being considered. A comparison of the yield and feeding value of the first, second and third crops was also made a part of the investigation, and as with the different cuttings, the composition and digestibility formed a part of the work. In conducting this experiment to determine the comparative feeding value of the various cuttings and of the different crops of alfalfa, some …

Bulletin No. 60 - Poultry Experiments, James Dryden

The experiments in egg production outlined in Bulletin No. 51 of this Station, were, in the main, continued during the year ending November 7, 1898. The results of this second year's work are reported herein.

Bulletin No. 57 - By-Products Of The Dairy, F. B. Linfield

UAES Bulletins

Soon after becoming connected with the Station, the writer, from observations made in various parts of the State, was impressed with the necessity for investigation looking to the profitable disposal of the by-products of the dairy, both at the factory and on the farm. The common method at the factories seemed to be to feed hogs on milk or whey alone, and where grain was fed, it was only given to finish the hog for market. This method of management did not appear to be successful, for it generally took the whole season to get one crop of hogs ready …

Bulletin No. 54 - Cattle Feeding, Luther Foster, Lewis A. Merrill

UAES Bulletins

For three successive seasons, just preceding the work herein detailed, experiments had been conducted at this Station for the purpose of determining the comparative yield and feeding value of early, medium and late cut lucern, also of the first, second and third crops, the object being to decide, by chemical tests and feeding trials, at just what period of its growth lucern should be cut for the best results, and, pound per pound, the relative value of the different crops.

Bulletin No. 43 - 1. Dairy Herd Record For 1984-95. 2. Winter Feeding Experiments With Dairy Cows. 3. Some Suggestions On The Building And Equipment Of Factories., F. B. Linfield

UAES Bulletins

The Dairy Department of this Station was fully organized by June 1894. The latter part of 1893 and early part of 1894 were devoted to fitting up the dairy rooms and getting the' necessary appliances and machinery in place. As our dairy herd was too small for experimental work, it was decided during the spring of 1894 to increase the number to fifteen head. The selection and purchasing of those cows were left to the writer.

Bulletin No. 42 - Creaming Experiments, F. B. Linfield

UAES Bulletins

During the summer of 1894, before our hand separator was fitted with power attachment, the writer found it scarcely practicable to run the separator, so that most of the milk was skimmed by deep setting. Although the usual methods of procedure were practiced, it was found impossible to get results that were satisfactory, or that would approximately compare with those reported from many eastern stations. Because of this and because ' the larger proportion of our dairymen use some method of setting, it was decided to undertake a series of experiments that might throw some light upon the subject. As …

Bulletin No. 40 - The Economic Production Of Pork, A. A. Mills

UAES Bulletins

This bulletin contains the detailed results of two years' work along the lines indicated, and a summary of the work of four years as far as it has been carried along these same lines.

In the summer of 1894, twelve lots of pigs were selected. They were purchased in Cache valley, and were a fair average of the pigs raised here. It was originally intended to put three pigs in each division, but just at the time of beginning the experiment it was difficult to procure enough animals of the proper age and size, so that the lots contained but …

Bulletin No. 36 - Relative Value Of Corn And Oats For Horses, A. A. Mills

UAES Bulletins

This Bulletin reports the continuation of the study of the best nutritive ratio for horses under moderate work. The experiment was so arranged that a direct comparison could be made between oats and corn as the principal grain ration. The work was planned by Prof. J. W. Sanborn, who was then Director of the Station.

Bulletin No. 30 - Narrow Vs. Wide Nutrituve Rations For Horses, J. W. Sanborn

UAES Bulletins

In the third annual report of this Station (1892) the result of feeding wide and narrow nutritive rations to horses was given. This trial was favorable to the narrow nutritive ration. This ration was made up of clover, oats and wheat", while the wide ration was made up of timothy and corn. The trial ran through the summer, when the influence of what has been termed heating food, like corn, might be less effective than in the winter season. Many believe that the more varieties of food given the better the result, as the palatableness of food, it is claimed, …
