Beef production system

The document presents an overview of beef production systems, detailing key processes such as breeding pure breeds, cow and calf production, and baby beef production. It highlights the objectives and feeding requirements for each stage to optimize cattle growth and replacement. Additionally, it addresses factors for selecting production systems, including expected gains and grazing periods.

Presentation on Beef production system By Rashed Hasan Nayeem Roll No – MS- 170717 Session – 2016-17 Biotechnology & Genetic Engineering Discipline Khulna University
Beef Cattle Production System 1. Breeding pure breeds 2. Cow and calf production 3. Growing stockers 4. Baby beef production 5. Finishing cattle 6. Duel purpose production
1. Breeding pure breeds Process of produce replace animal General Consequence 1. Pure breed bull and graded cow are used 2. Difference between the prices of pure breed bull & graded caw should be small 3. Forage based feeding i.e. grass, hay or silage in sufficient amount Objective 1. To produce replacement animal 2. To produce furnishing foundation stock 3. To provide breeding stock to commercial cattle producers
2. Cow and calf production Produces weaned feeder calves for further grazing and/or feeding General Consequence 1. Use usally adult female cows, their calves and heifers 2. Pregnant cows are bought 3. Sold after they have been weaned at the age of 1-2 years 4. Older cows sold to slaughter after their reproductive years have ended. Otherwise cost will be increased Feeding 1. Needs plenty of pasture and other forms of roughage 2. For this reason, they require more land than other cattle operations 3. Posture may be native or ‘improved’
3. Growing stockers The process of growing and developing calves from weaning weights to yearling weight of when the ready to enter a feedyard for finishing. Objective 1. Heifers and steers are marketed after one year 2. Heifers can be used as replacement animal Feeding 1. Stocker calf gaining over 3 pounds per day 25-30% crude protein and 75 to 85% digestibility 2. Calf to gain 2 pounds per day digestibility should be 67% or greater 3. Often calves grazing summer grasses gain only 1.5 pounds per day or less without supplementation.
4. Baby beef production Superior breeding Maintenance of body fat 1. Newborn calves from cow & sold after 12-18 months 2. Calves are ranging their mother from a few hours to a few days (3 Days) & consume a diet, mostly milk-base protein & added vitamins & minerals. 3. Grain-fed calves (3/4 weeks) normally consume a diet of milk replacer for the fist six to 8 weeks.
5. Finishing cattle 6. Duel purpose production 1. Cattle are usually finished for slaughter given grain limited 2. Include more roughage & less concentrate feeding during last 120 days 3. No need to provide protein 1. Daily breeds are sometimes selected for both milk and beef 2. General feed supply is provide 3. When in need, farmer sell the cow
Factors for selecting a production system • Average daily gain- the expected average rate of gain per animal • Gain/Acre- the amount of gain expected to be produced per acre • Grazing period- the expected number of days when the forage system can be grazed at a specified stocking rate • Stocking rate- the expected number of animals capable of being grazed on a given acre for the specified grazing period
