Feedlot Cattle Management

These flashcards cover key concepts from the lecture on Feedlot Cattle Management, focusing on feed strategies, health concerns, and growth efficiency.

Receiving Cattle

Processes involved in the initial intake and care of cattle in a feedlot.

Step-Up Ration

A feeding strategy gradually increasing concentrate in the diet to adapt cattle to higher energy feeds.

Urea

A non-protein nitrogen source used in cattle diets, related to protein synthesis.

Bet-Agonists

Non-hormonal compounds that bind to muscle cell receptors to increase muscle growth.

Ionophores

Compounds that alter microbial fermentation in the rumen, improving feed efficiency.

Thiamine deficiency

Can lead to Polioencephalomalacia (PEM) in cattle, a neurological disorder.

Limestone in Diet

Used to prevent urinary calculi in cattle.

Antibiotics

Medications used for disease control and prevention in feedlot cattle.

Buffers

Supplements that stabilize rumen pH in cattle, particularly under high-grain diets.

Estrogenic Compounds

Synthetic or natural substances that mimic estrogen, found in meat from implanted cattle.

Volatile Fatty Acids (VFAs)

Fatty acids produced during fermentation in the rumen, important for energy.

Acetate

A type of volatile fatty acid primarily produced in forage-based diets.

Propionate

A type of volatile fatty acid primarily produced in grain-based diets, important for energy.

Butyrate

A volatile fatty acid important for energy and health of the rumen lining.

Injection Site Abscesses

Infections that can result from improper injection techniques in cattle.

Preferred Injection Site

The recommended location on a cattle body for safe and effective injections.

Feedlot Cattle

Cattle raised in confined spaces for the purpose of efficiently producing beef.

MGA (Melengestrol Acetate)

A feed additive used to control estrus in heifers.

Feed Efficiency

Measured output of meat against feed consumed, indicative of production efficiency.

Knee Joint Score

A scoring system to assess the condition of a feedlot cattle's knee joints.

Monensin

An ionophore used to promote growth efficiency and reduce methane in cattle.

Lasalocid

An ionophore used to improve feed efficiency and control coccidiosis.

Non-implanted Cattle

Cattle that have not received hormone implants for growth promotion.

Phytoestrogens

Plant-derived compounds that mimic estrogen and can have health effects.

Cattle Diets

The specific nutritional plans formulated for achieving desired growth and health.

Implants

Hormonal products used in cattle to promote growth.

Sub-therapeutic Antibiotics

Use of antibiotics in low doses to promote growth rather than treat illness.

Slight Surface Erosion

Indicates early signs of joint issues in cattle, marked by a score of 4.

Stiffness and Lameness

Health issues possibly linked to feed additives like beta agonists in cattle.

Animal Welfare Concerns

Issues related to the treatment and care of livestock in production settings.

Cattle Welfare vs Food Safety

Distinction between humane treatment of animals and the safety of produced food.

Environmental Impact

Effects of beef production practices, including use of hormone implants and feed additives.

Performance Metrics

Measurements used to evaluate the growth, efficiency, and health of feedlot cattle.

Injection Techniques

Protocols for administering vaccinations or treatments to minimize harm and complications.
