Better Rations - More Eggs

Well-bred and well-fed hens are conceded to be economical producers of a very wholesome food product, eggs, but our hens are not miracle workers and they insist on the right kind of raw material for building the egg. Nebraska poultry growers fortunately have all the natural feeds - corn, wheat, oats, barley, and dairy and packing house by-products - readily available at lower cash prices than prevail in most other states, and so our special problem is that of combining them so that eggs may be produced at the lowest cost per dozen

Effect of Manganese and Iodine Additions in a Specific Ration for Laying Hens

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

Nutrient Requirements of Growing Chicks

The object of our experimental work was to establish if possible certain principles of poultry nutrition, permitting later a better combination of natural feedstuffs with the highest growth efficiency

Electric Chick Brooding Studies

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

Some Observations on Humidity and Weight Loss in the Incubation of Turkey Eggs

1. Turkey eggs which are incubated under chicken hens lose from 11 to 13 per cent of their original weight during the first 24 days of incubation. Small turkey eggs lose relatively more weight than large eggs incubated under the same conditions. 2. Considerable variation was observed in the weight loss during the first 24 days of incubation of eggs of approximately the same size when incubated in the same environment. The range was from 7 to 24 per cent of the original weight. Differences in shell texture may account for these variations, although care was taken to select only apparently normal eggs with good texture for these experiments. 3. Variations in the weight loss during incubation within the limits of our observations as herein reported apparently have no significant correlation with the growth rate during the first eight weeks of the life of the poult. 4. Rate of air movement and humidity as environmental factors apparently influence hatchability more during the last four days than during the first twenty-four days of the incubation period. 5. It is probable that for turkey eggs cabinet incubators require conditions during the last four days of the hatch that are somewhat different from those which have proved satisfactory for hatching chicken eggs

The Insects and Mites Injurious to Poultry in Nebraska and Their Control

There are a number of different kinds of insect and mites (arthropods) that are more or less injurious to poultry in Nebraska. This circular is designed to give practical information concerning these pests and their control

The Utilization of Food Elements by Growing Chicks. XI. A Comparison of Ground Wheat and Ground Rye in Rations for Growing Chicks

1. The effect of replacing the shorts and bran of a standard ration by ground wheat or ground rye was studied with two lots of newly hatched chicks. 2. Comparisons were made on the basis of equal intakes of dry matter and nitrogen by all chicks. 3. The wheat-fed lot made a significantly greater gain than the rye-fed lot. 4. Several cases of curled-toe paralysis occurred in the two lots, and a tendency to cannibalism appeared in the rye-fed lot
