Ec89-263 Nebraska Breeding And Calving Record Book

University of Nebraska-Lincoln Extension: Historical Materials

This Breeding-Calving Record Book will serve as a useful aid in keeping complete and accurate beef performance records. Performance records have long been recognized as a valuable tool in the selection of genetically superior cattle; in addition, performance records are now being used to eliminate much of the "guesswork" from herd management decisions.

G89-942 Can You Afford To Use Bovine Somatrophin (Bovine Growth Hormone)?, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

Factors to consider before using Bovine Somatrophin in your dairy herd are covered here.

Much has been written recently about the effect of administering Bovine Somatrophin (BST) to dairy animals. The expected increase in income that could be generated by the use of BST catches producers' attention.

Before any producer uses BST, however, there are a few questions that should be addressed. The most crucial is, "Can BST administration be cash flowed in my dairy operation?"

The answer to this question is dependent on three crucial areas--your current herd average, herd management situation, and the costs involved in the application …

G89-989 How To Interpret The New Animal Model For Dairy Sire Evaluation, Jeffrey F. Keown

University of Nebraska-Lincoln Extension: Historical Materials

In question and answer format this NebGuide addresses changes in genetic evaluations of both dairy cows and sores.

Why is the United States Department of Agriculture (USDA) changing the dairy sire and cow evaluation system?

The answer is simple. The Animal Model for genetic evaluations is more accurate than the old Modified Contemporary Comparison Method (M.C.C.). Previously the major limiting factors to implementing the Animal Model were computing costs and memory requirements. With the advent of new Super Computers, the computations are feasible on a national scale.

What is the Animal Model?

The Animal Model simultaneously evaluates cows and sires …

U.S. Grazing Lands: 1950-8, Arthur B. Daugherty, United States Department Of Agriculture, Economic Research Service

All U.S. Government Documents (Utah Regional Depository)

U.S. livestock owners grazed their herds on 817 million acres in 1982, down about 20 percent from 1950. This drop resulted primarily from improved productivity of grazing lands, as animal units of cattle and sheep increased more than 30 percent during 1950-82. Only the Southern Plains, of all farm production regions, showed an increase in land grazed during 1950-82. Non-Federal grazing land consisted of rangeland (67 percent), pastureland (21 percent), and grazed forest (12 percent). More than 30 percent of the non-Federal range and pasture was rated in good to excellent condition, and 12 percent of the grazed forest had …

Growth Stimulants, Nyle J. Matthews

Archived Agriculture Publications

A tiny pellet inserted under the skin of a calf's ear may increase weight gains as much as 15 to 20 percent. This same result would take years to accomplish through breeding and selection. These tiny pellets are growth stimulants. They are made of hormones that are constructed to slowly release minute amounts into the blood stream that stimulate the animal to produce natural body hormones. One of these hormones is a growth hormone. It regulates the rate of growth of the animal. Increasing the rate of growth will almost always improve feed efficiency and reduce maintenance costs. These pellets …
