Fun facts There are over 1 billion cows alive today in six continents around the world. 25% of the Earth’s land is used as pasture for cattle raising. In Australia, the number of cows exceeds the number of people by 40%, and is a major cause of land degradation and soil erosion due to overgrazing. In South America there are 9 cows for every 10 people. In Argentina, Paraguay, Uruguay, and Brazil, the # of cows equals or exceeds the # of people. In America, there is one cow for every 2 ½ people
12
Western European countries produce 17% of output.
More fun facts The United States produces 22% of the total beef output in the world, & North and South American continents combined produce 43% of total output. Western European countries produce 17% of output. The beef industry is the 4th largest manufacturing industry in the country, and generates 36 billion $ annually. California is the largest dairy producer in the states, with an average of 665 cows per dairy farm, while the national average is 100/dairy farm. California’s milk production per cow is 20,788 lbs, 17% higher than the national average.

Example of a Three Breed Rotational System
14
BREEDING SEASON MGT. I Breeding Soundness Exam
Natural Service with Bulls Yearling – 10 to 20 females Two Year Old – 20 to 30 females Mature bull – 30 to 40 females Artificial Insemination Less than 5% of cows in commercial herds Up to 40% of cows in seedstock herds
15
BREEDING SEASON MGT. II Limited season results in uniform calf crop
60 days would be ideal 100 to 120 days is more common Michigan Beef Cows Calving by Month Jan. & Feb % March % April % May % Other %
16
BREEDING SEASON MGT. III
At weaning (7 mo.) heifers should weigh 45% of mature weight. At breeding (15 mo.) heifers should weigh 65% of mature weight. At calving (24 mo.) heifers should weigh 85% of mature weight. Measure pelvic areas prior to breeding Use light birth weight and low birth weight EPD bulls for mating to heifers
18
MICHIGAN COW CALF NUTRITION
Pasture 5/15 to 10/30 – 165 days 1 to 5 acres per cow calf pair Harvested Forage 11/01 to 5/14 – 200 days Corn stalk residue – 30 to 60 days Grass-legume hay or silage – 140 to 200 days Free Choice Minerals Salt, Ca, P, Mg + Trace Minerals Clean fresh water
19
COMMON NUTRTIONAL PROBLEMS in BEEF COWS
Thin Cows Body Condition Scores (1 to 9) 5 to 6 is ideal Calving Difficulty & Delayed Rebreeding Dry vs. Lactating Fat Cows Calving Difficulty and Reduced Milk Flow Legume Bloat Grass Tetany
20
SEPARATE HERD INTO MANAGEMENT GROUPS
Bred Heifers & Thin Cows Dry Mature Cows Lactating Cows Weaned Heifer Calves Mature Herd Sires Young Bulls
21
HERD HEALTH PROGRAM I Calving Season Castrate & Dehorn
Colostrum within first hours after birth Iodine navel Selenium – Vitamin E Scour Vaccine (E.coli 7/or Viruses) Castrate & Dehorn Implant non replacement calves Vaccinate Cows (IBR, BVD, PI3 + Lepto)
22
HERD HEALTH PROGRAM II Pasture and Breeding Season
Deworm & Control Flies Vaccinate heifer calves for Brucellosis Consider Blackleg & Malignant Edema Creep feeding is optional Keep free choice mineral available
23
HERD HEALTH PROGRAM III
Preweaning Vaccinate calves for IBR, BVD, PI3, Blackleg & Hemophilis somnus Castrate and dehorn if not done earlier Get calves used to eating grain & drinking water from troughs Weaning Time Pregnancy check females exposed to breeding
24
HERD HEALTH PROGRAM IV Late Gestation Booster vaccinations
Grub & lice control Late Gestation Check mineral for P and Se Treat for lice if they are a problem Consider scour vaccine for cows & bred heifers
25
RECORD KEEPING 27.6% of beef cow calf operations have no records at all. 65.2% keep records by hand Source- National survey of 3,300 producers in 48 states
26
Types of Records Inventory Ancestral Performance Health
Birth, weaning and yearling data Health Vaccinations and examinations Financial – IRM & SPA
27
EXPECTED PROGENY DIFFERENCES (EPD)
EPDs can be calculated for any trait that we can measure. EPDs are estimates of the genetic ability of animals to transmit to their progeny EPDs are expressed in the same units as the trait is measured Analyses are done by the national breed associations
28
EPDs continued Breed average is not “0”.
EPDs change over time as more information enters the analyses. Most breeds run two analyses per year. They are widely used and widely accepted in the industry Accuracy ranges from 0 to .99
29
IRM & SPA Integrated Resource Management (IRM) is a system approach to managing a farm or ranch. Standardized Performance Analysis (SPA) is a way of analyzing records of both production and financial performance of a farm or ranch in order to make better decisions and impact profitability.
30
2000 ILLINOIS SPA SUMMARY Calf Crop Weaned 82.9%
Average Weaning Weight 486 lbs. Lbs.weaned/Cow Exposed 420 lbs. Annual Cow Cost $ 305 Feed cost was $ 209 Breakeven Calf Price $ 73/cwt. Investment per cow $ 1,858
31
HOW TO IMPROVE PROFIT Improve Reproductive Rate Wean Heavier Calves
Wean Higher Value Calves Develop Alliances and Retain Ownership Reduce Cow Herd Costs Use cattle inventory and price cycles in management decision making
32
CATTLE INVENTORY & PRICE CYCLES
High inventory = low prices Low inventory = high prices Historically cattle inventory cycles have averaged 9.6 years long from peak to peak. In 2001, we are at the low inventory part of this cycle. Cow calf producers should be profitable for the next 4 to 5 years.
34
STOCKER/BACKGROUNDER
Purchase weaned calves in fall, sell in the spring Goal is 1.5 to 1.75 lb. ADG Moderate energy, high roughage rations Growth and normal development are the goals Fattening is not a goal. Grazing winter wheat in the southern plains states from November to March Wintering on hay &/or silage in Michigan
35
STOCKER/BACKGROUNDER continued
Buy yearlings in late winter and graze in summer. Goal is 180 to 300 lb. gain in 120 to 150 days Some programs will combine both a winter stocker and summer grazing program before entering the feedlot.
37
STARTING CATTLE ON FEED
First day begin with top quality grass hay Second day top dress hay with grain or silage Transition to high energy ration should be made over 10 to 14 days to avoid digestive upsets. Don’t use all NPN supplements until calves weigh at least 600 lbs. Keep fresh feed and water available at all times
38
FEEDLOT NUTRITION Grains – Corn, Barley & Milo
Roughages – Corn Silage, Alfalfa Hay or Haylage Protein Supplements Soybean or Cottonseed Meals Brewers Grains Urea or Anhydrous Ammonia
39
NUTRITIONAL PROBLEMS Acidosis on high energy rations
Ionophores (Rumensin or Bovatec) help Founder (laminitis) on high energy rations Bloat Urinary calculi Need Ca:P ratio > 1.1 Often occurs on high energy diets
40
FEEDLOT STEERS & HEIFERS
Steers gain 8% to 15% faster than heifers of same body size. Steers consume 5% to 10% more feed than heifers. Heifers require 2% to 10% more lbs. of feed per lb. of gain than steers Some feeders tend to over fatten heifers To be equal in profit, heifers must be purchased about 10% to 15% less per cwt. than steers.
41
FEEDLOT STEERS & BULLS Bulls gain more rapidly and more efficiently than steers. Bulls produce leaner carcasses that are more variable in tenderness than steer carcasses. Bulls are more difficult to manage than steers or heifers. There is only a limited market for bull beef.
42
AGE OF FEEDLOT CATTLE Yearlings gain 10% to 20% faster than calves depending on weight and condition. Yearlings consume 10% to 40% more feed than calves. Yearlings are less efficient in converting feed to gain than calves. Yearlings require fewer days in the feedlot to reach final weight and carcass grade. Western U.S. feedlots prefer to feed yearlings.
43
BREED EFFECTS Larger continental breeds gain faster than British breeds, but must be carried to heavier weights to grade choice. There is little difference in feed efficiency when fed to the same carcass endpoint. Holsteins require about 10% more feed per lb. of gain than beef breeds but ADG is similar to beef breeds.
44
EFFECT OF BODY CONDITION
When placed on comparable diets, thin cattle gain faster and more efficiently than fatter cattle. This phenomenon is called “compensatory gain”. Cattle feeders try to avoid buying fat feeder cattle unless they are priced somewhat lower per cwt. than thin feeder cattle.
45
FEEDLOT PROFIT OR LOSS Dekalb feedlots average profit per head over a 23 year period was $ 26. Profitability is influenced by changes in the grain and cattle markets. Risk can be controlled by use of contracts and trading for future market access. Marketing skills are critical for success.
