Overview of the beef industry in the U.S. and Alabama
- Trends in U.S. cattle population
- State rankings for all cattle, brood cows, fed cattle
- Overview of U.S. beef industry segments
- Current issues/goals in the beef industry
(1995, 2000, and 2005 Beef Quality Audits)....You can go to Google and search for "Beef Quality Audit." (Include the quotation marks.)
Two documents have been included here:
An excutive summary of the 2000 Beef Quality Audit
(This document describes how the beef quality audits were done.)
"Beef" magazine brief summary of the 2005 Beef
Quality Audit
- Beef cattle alliances
"Alliance" is a buzzword in the cattle industry and one with growing clout.
In an article published in the January, 2001,
Progressive Farmer quoted Michigan's Harlan Ritchie, "More has happened
in the beef industry in the last 24 months than in the last 24 years." He
further said, "Branded products [often produced by alliances] held 10 to 12%
of beef's market share in 1998. By 2002, these will be 25 to 30% of products."
The August 22, 2001, issue of Beef Magazine had suggestions for choosing an alliance,
and characteristics of a successful alliance. That article has been reprinted
here.
The Maverick Ranch
is just one example of an alliance.
Maverick Ranch's website was chosen as an example because it has several links
to nutritional information and information on hormones and pesticides.

Nutritional Considerations for the Beef Herd
- Overview of significant features of ruminant digestion of feeds and metabolism of nutrients
- Important nutrients for the beef herd
- Nutrient analysis and feed tags
- Forage quality
Note: Discussion of energy and protein supplementation
(parts E and F that follow) may be covered in the section on
stocker-yearlings (high-quality forages) and managing the cow herd
for a high percent calf crop (lower-quality forages)
- Energy and protein supplementation of cattle grazing lower quality forages
- Effects of grain supplementation (high-starch feeds)
- Effects of protein supplementation

utilization is reduced
- NPN vs true protein
- Liquid supplements
- Urea not well utilized on forage diets
- Molasses can enhance digestibility and intake of low quality roughage
- Which ingredients are good (well-utilized) protein sources?

Chapter 5 (all)
|
B. Management for high percent calf crop weaned
- Heifers must reach desired weight to be bred to calve at 2 years old
- Desired weights to have a high percentage cycling at breeding time (generally, at least 65%
of expected mature weight)
- Crossbred heifers reach puberty earlier and at lighter weights than straightbred
- Nutrition programs for replacement heifers
- Breed heifers to calve early in calving season
- Heifers calving early are more likely to be pregnant when 2 and 3 years old
- Importance of calving early in calving season on weaning weights
- Save more heifers than needed as potential replacements
- Keep heifers separate from mature cow herd
- Heifers have longer postpartum intervals than mature cows
- Good nutrition shortens the postpartum interval
- Social dominance of older cows
- If complete separation is not possible, separate them at least 60 days before calving.
- Cows/heifers should have proper body condition
(see ACES ref. "Body Condition Scores")
- General: Have cattle gaining weight going into calving season
- "120 Critical Days"
- Body condition scores (BCS)
- Nutritional management (emphasis on the period beginning 1-2 months before calving until the cow has been re-bred)
- Nutritional considerations for supplementing the herd
(see Neumann & Lusby ref.
and ACES - "Hay Production")
- Protein supplementation
Effect on forage digestion and intake; NPN vs. Natural protein
- Liquid supplements
Advantages and controversies; Ingredients used...Which work? Which don't?
- Energy (grain) supplements
Response probably not as good as expected; high-starch feeds and reduced fiber digestibility; economics
- Minerals for the cow herd
- Close observation at calving, particularly heifers
(see ACES ref. "Calving Management")
- Incidence of dystocia
- Nutrition: limit-feeding does not improve dystocia problems but probably will increase the postpartum interval
- Control time of calving? (Day time vs night)
- Select for proper birth weights to minimize dystocia
- Relationship of weaning wt. and yearling wt. to birth weight
- Cows given assistance at birth have longer postpartum intervals
- Birth weight most effectively controlled through sire selection. EPD's more reliable than sire's own birth weight
- Pelvic area measurements
- Bull management
- BSE, libido
- Factors that can temporarily decrease fertility
- Cow-to-bull ratio
- Nutrition for the bull (including newly purchased bulls)
- Herd health management
(see ACES ref. "Herd Health Management")
- Management after day 7 postpartum
- Other management practices for early return to estrus

C. Management for heavy weaning weights
- Short calving season (60 days)
(see ACES ref. "Get Control of Health by..."
and "Calving Season Management Alternatives")
- Lose 30-40 lb. in weaning weight per estrous cycle
- Calves can be managed as uniform groups; better market price for uniform groups
- Estrous synchronization program (for herd with normal estrous cycles)
- Importance of good forage program
- Calving season should match forage supply and nutrient quality with cow's milk production and calf's ability to directly utilize forages.
- Growth stimulants for calves
- Synovex C, Ralgro, Compudose
(see ACES ref. "Implants")
- For replacement females, use only approved products and strictly adhere to label instructions. Improper use can be disastrous.
- Creep feeding - pros and cons
- Selection, primarily through sires
- Milk and Weaning Wt EPD's (Use Yearling Wt EPD if possible)
- Stay within limits of available grazed forages
(Negative effect on BCS and reproduction, thus greater need for harvested and purchased feeds)
- Crossbreed (Well-planned program)
- Heterosis increases growth rate of calf & milk production of cow
- Crossbreeding results in ~20% increase in lb. of calf weaned per cow exposed
1) 65-75% of this heterosis is due to increase fertility
2) 25-35% of heterosis is due to growth rate of calf and increased milk prod.
- Herd health
- Dystocia and inadequate colostrum (first 24 hr.) have negative effects on weaning weight
- Follow recommended herd health guidelines for geographic area

D. Management for low annual cow costs
- Keep accurate records so expenses can be analyzed
- Must know costs to calculate annual cow costs and net returns
- Particularly note feed, machinery, labor, interest, and health costs
- Feed costs account for 50-75% of annual costs
1) From weaning to last third of gestation is time to use cheap roughage such as crop aftermath
2) Determine most economical feed environment and decide what biological type of cow will match this enviornment
- Labor accounts for 15-20% of annual cow costs
- Interest charges average 10-15% of annual cow costs
- Managing feed costs
(see ACES ref. "Reducing Stored Feed
Requirements")
- Calving season -- Normally ~30-45 days prior to grazed green forage to utilize peak of high quality nutrients
Other considerations -- cool-season grazing; normal weather conditions at calving; normal temperatures during breeding
- BCS of cows at start of calving and breeding vs available feed (grazed, harvested, or purchased) Correct biological type of cow?
- Palpate cows 45-60 days after breeding season; sell open cows and heifers
- Increasing cow numbers on same land area
- Overhead costs (land payments, insurance, interest, taxes, vehicles) relatively constant
- Cow numbers can increase by improving forage programs
- Lb. of calf weaned per acre probably more important than calf weaning wt. May need to change biological type of cow.
- Biological type of cow
- Puberty. Should have first calf at 23 mos. of age utilizing available resources.
- Calving ease. Affects labor, health costs for the calf, and length of postpartum anestrus period for the cow
- Milk production. Match for available feed resources. Low production leads to light calf and "fat" cow. Too much milk results in a heavier calf but decrease BCS of cow.
- Mature weight. Moderate weights (1,000-1,250 lb.) generally most profitable. Feed needed for maintenance is proportional to body size.
- Rebreeding. Maintain adequate BCS utilizing primarily grazed forages and minimize need for harvested or purchased feed.
- Longevity. Produce a calf every 12 mos. An "efficient" cow that remains in the herd helps decrease replacement heifer costs.
