Judging Quality In Dairy Products, P. A. Downs
Judging Quality In Dairy Products, P. A. Downs
Nebraska Agricultural Experiment Station: Historical Circulars
In the dairy industry increasing attention is being paid to the question of quality of products. The well established system of buying and selling butter and cheese on the basis of quality by score or grade is practiced in the principal markets of the world. The other dairy products, while not marketed by score, are receiving more and more attention in this respect. As more information becomes available and the judging better standardized, other dairy products will doubtless be sold by grade.
Artificial Insemination Of Turkeys, H. L. Wiegers
Artificial Insemination Of Turkeys, H. L. Wiegers
Nebraska Agricultural Experiment Station: Historical Circulars
Artificial insemination should be used for turkeys when results from natural matings are unsatisfactory. There is no hard and fast fertility rule to follow and each breeder will have his own basis of appraisal for the different varieties of turkeys. But one can say that when fertility drops below 65 per cent it is time to take action.
50 Years Of Research At The North Platte Experiment Station, W. W. Burr, J. C. Adams
50 Years Of Research At The North Platte Experiment Station, W. W. Burr, J. C. Adams
Nebraska Agricultural Experiment Station: Historical Circulars
The North Platte Experiment was established fifty years ago. So many changes have occurred since then that few people remember why research in dry land agriculture was started in Nebraska and other Great Plains states. In order to get a proper perspective, it may be well to consider some early history.
Electric Chick Brooding Studies, F. D. Yung, F. E. Mussehl
Electric Chick Brooding Studies, F. D. Yung, F. E. Mussehl
Nebraska Agricultural Experiment Station: Historical Circulars
Perhaps one of the most valuable lessons to be learned from a study of chick brooding is that good results can often be obtained in more ways than one. In carrying on work with electric brooders at the Nebraska Agricultural Experiment Station, special attention has been given to such factors as insulation and to other details of design which effect economy of operation and ease of construction. Low cost rather than "cheapness" has been the ideal. The work has been cooperative between the Agricultural Engineering Department and the Poultry Husbandry Department of the University of Nebraska.
Feeding Milking Shorthorn Steers, M. L. Baker, V. H. Arthaud, C. H. Adams
Feeding Milking Shorthorn Steers, M. L. Baker, V. H. Arthaud, C. H. Adams
Nebraska Agricultural Experiment Station: Historical Circulars
The objectives of the feeding work were to provide the producer with feed-lot data and where possible with slaughter data for Milking Shorthorn steers. As a definite breeding research program with the Milking Shorthorn herd was planned, it also was believed that information about the beef-making qualities of the steers should be of equal importance with milk and butterfat production records.
Developing Rapid-Feathering Chickens, I. L. Williams, H. L. Wiegers
Developing Rapid-Feathering Chickens, I. L. Williams, H. L. Wiegers
Nebraska Agricultural Experiment Station: Historical Circulars
The object of this circular is to acquaint the poultry producer, hatchery operator, or any other person endeavoring to develop improved strains of chickens with a satisfactory method for eliminating slow-feathering individuals from his flock.
The Nebraska Egg Cooler, I. L. Williams, F. E. Mussehl
The Nebraska Egg Cooler, I. L. Williams, F. E. Mussehl
Nebraska Agricultural Experiment Station: Historical Circulars
Every producer knows that heat is harmful to the quality of eggs, and that the first step in holding fine egg quality is prompt removal of the animal heat. The Nebraska egg cooler has been developed for this purpose. Construction costs are moderate, and repeated observations demonstrate the effectiveness of the principle. Its basic factor is the temperature-reducing effect of cool, humid air passing over the eggs, as soon as possible after they are gathered.
Vitamins For Poultry, F. E. Mussehl, C. W. Ackerson
Vitamins For Poultry, F. E. Mussehl, C. W. Ackerson
Nebraska Agricultural Experiment Station: Historical Circulars
Vitamins are chemical substances essential for the maintenance of life, growth, and reproduction. Their effects are out of proportion to the relatively small amounts required. Fortunately, most of these essentials are widely distributed in nature, and an adequate ration can nearly always be provided by using logical combinations of common feedstuffs. Under certain conditions, however, the use of vitamin-containing concentrates may be desirable. In planning practical rations, it should be recognized that the plant leaf is the source of most vitamins. Milk and meat products make important vitamin contributions to the diet in addition to their proteins and minerals. Direct …

Poultry Progress: Our Egg Marketing Job, F. E. Mussehl, H. C. Filley
Poultry Progress: Our Egg Marketing Job, F. E. Mussehl, H. C. Filley
Nebraska Agricultural Experiment Station: Historical Circulars
Eggs are one of the products which Nebraska farm families exchange for the necessities and comforts of life. Although values are measured in dollars and cents, the interest of the producers centers in the amount of useful goods and services that the eggs will buy rather than in the price per dozen or per case. Farmers are interested in a fair exchange value because they wish better homes, better schools, better churches, and better communities in general. In the typical Nebraska community, not only farmers but physicians, merchants, mechanics and school teachers are dependent for their income, either directly or …
Poultry Progress: What Are Good Chickens?, F. E. Mussehl
Poultry Progress: What Are Good Chickens?, F. E. Mussehl
Nebraska Agricultural Experiment Station: Historical Circulars
The desire for improvement is one of the highest of human virtues. Folks everywhere want good chickens. The poultry business is a competitive enterprise, and it is imperative that we have the best stock possible for the particular job to be done. But what are good chickens? Is there confusion about the term? Perhaps we can clarify the picture by asking one or two questions.
Poultry Progress: How Long Should A Chicken Live?, F. E. Mussehl
Poultry Progress: How Long Should A Chicken Live?, F. E. Mussehl
Nebraska Agricultural Experiment Station: Historical Circulars
Increased laying flock mortality has disturbed thoughtful hatcherymen, producers, processors, and research workers for several years, and very properly so, because hens which die before their time serve no useful purpose, except to raise in our minds the question, "Why?"
External Parasites Of Poultry And Methods For Their Control, O. S. Bare
External Parasites Of Poultry And Methods For Their Control, O. S. Bare
Nebraska Agricultural Experiment Station: Historical Circulars
External parasites cause severe losses to Nebraska poultry producers each year, and in many cases may be the deciding factor between success and failure. Under present circumstances, when maximum production is essential, prompt and effective measures must be taken to hold these saboteurs in check.
Effect Of Manganese And Iodine Additions In A Specific Ration For Laying Hens, F. E. Mussehl
Effect Of Manganese And Iodine Additions In A Specific Ration For Laying Hens, F. E. Mussehl
Nebraska Agricultural Experiment Station: Historical Circulars
This preliminary experiment does not answer all of the questions that are presented about manganese and iodine requirements. It can only be taken to indicate that for a typical situation with a typical ration of the type that many poultry producers use, there was no satisfactory evidence that egg production, hatchability and the viability of the hens was limited by manganese and iodine in the ration.
Use Milk - An Essential Food, University Of Nebraska - Lincoln
Use Milk - An Essential Food, University Of Nebraska - Lincoln
Nebraska Agricultural Experiment Station: Historical Circulars
The purpose of this publication is to furnish the housewife with information on ways to utilize more milk in the home, especially in the farm home where milk is readily available and an economical source of vitality and greater health for all the family.
Babcock Testing And Other Methods Of Analyzing Dairy Products, L. K. Crowe
Babcock Testing And Other Methods Of Analyzing Dairy Products, L. K. Crowe
Nebraska Agricultural Experiment Station: Historical Circulars
The manufacturing of dairy products on a commercial scale began about the middle of the nineteenth century and was greatly stimulated by the development of the centrifugal cream separator in the late eighties. The invention of the Babcock test in the early nineties overcame some of the difficulties that had developed in paying for milk upon its butterfat content, since it was early recognized that milk varied widely in that respect.

Cooling, Storage, And Transporation Of Milk And Cream, P. A. Downs, F. D. Yung
Cooling, Storage, And Transporation Of Milk And Cream, P. A. Downs, F. D. Yung
Nebraska Agricultural Experiment Station: Historical Circulars
The care given milk and milk products should be such that they will be relished by young and old alike. Greater use of milk can be encouraged by serving fresh milk cold. Cooling of milk also insures a fine product several hours after production. This is important not only for milk that is to be used, but for milk or cream that is to be sold.
Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott
Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott
Nebraska Agricultural Experiment Station: Historical Circulars
In Nebraska, a hustling frontier state in 1887, the legislature hesitated not at all in taking advantage of the provisions of the Hatch Act, and now that fifty years have elapsed since the Station was founded, seventy-five years since the Land Grant College Act was passed and the U. S. Department of Agriculture established, and almost twenty-five years since the Agricultural Extension Service was added, it seems worth while to present a general summary of achievement within the state. The main object will be to show some of the important things that have been learned through the investigations of the …
A Manual For Hog Raisers, W. J. Loeffel
A Manual For Hog Raisers, W. J. Loeffel
Nebraska Agricultural Experiment Station: Historical Circulars
Hogs are one of Nebraska's principal sources of agricultural income. The popularity of the pig is doubtless due largely to his efficiency as a meat producer. He uses less feed to make a given gain than either the steer or the sheep. On being slaughtered, the pig dresses out a higher percentage of meat than either of the other two meat animals. Since pork is generally fatter than beef or lamb, it has a higher energy value. Pork lends itself to curing processes and, as cured meat and lard, occupies an important place in the world's commerce. Processing aids in …
Feeding And Care Of Calves, R. R. Thalman
Feeding And Care Of Calves, R. R. Thalman
Nebraska Agricultural Experiment Station: Historical Circulars
It is not infrequent that considerable difficulty is encountered in raising calves with limited amounts of milk or none at all. Requests for information on calf gruels, mixed grain feeds, and commercial supplements are frequent enough to make a short circular upon this subject seem desirable. Furthermore, as the more diversified agricultural program gets under way these requests are increasmg.
Determining The Sex Of Day-Old Chicks, H. E. Alder
Determining The Sex Of Day-Old Chicks, H. E. Alder
Nebraska Agricultural Experiment Station: Historical Circulars
More than 2,000 years ago people were interested in determining the sex of the embryo in hatching eggs and the sex of day-old chicks. No method of determining the sex of day-old chicks (except of course in sex-linked chicks) was of the slightest value until the Japanese method was discovered and developed. About 1925 Japanese scientists discovered the presence of a rudimentary copulatory organ located on the ventral rim of the cloaca which was present in all day-old males and only a few day-old females.

It becomes possible to understand some of the reasons for the occurrence of disorders among the newborn of animals kept under the usual conditions imposed by domestication. Among these, the subject of this circular, White Scours in Calves, occupies a prominent place.
Why Some Hens Lay More Eggs Than Others, H. E. Alder
Why Some Hens Lay More Eggs Than Others, H. E. Alder
Nebraska Agricultural Experiment Station: Historical Circulars
The 1929 report of the Storrs Egg Laying Contest, which has been conducted at Storrs, Connecticut, twenty-one years, shows that the best pen of ten hens entered laid 2,802 eggs, and the poorest pen laid 829 eggs. In the best pen the average egg production per hen was 280, 2 eggs as compared with 82.9 eggs per bird in the poorest pen. Why did the one pen lay so many eggs, and the other so few? This prompts us to try to find out what factors are responsible for the number of eggs a hen lays in the course of …
The Common Intestinal Roundworm Of Swine, H. M. Martin
The Common Intestinal Roundworm Of Swine, H. M. Martin
Nebraska Agricultural Experiment Station: Historical Circulars
The large intestinal roundworm of pigs is a very common parasite, and is probably present in every hog raising district of Nebraska. Until the last few years the true nature of this parasite was unknown. Little did we realize the actual harm done by this worm; but through the scientific investigations of Stewart, Ransom, and others we now know that this parasite causes heavier losses to the breeder and feeder of swine than any other now common in Nebraska.
