ANSC EXAM 2

Clinical

Visible signs

Subclinical

No visible signs

Pathogen 4 step process

1. Enter the body 2.Adapt/reproduce 3.Exit the body and 4.attacck new host

Etiology

fancy word for the cause of a disease

Pathology

The study of diseases and their effects on the body.

Passive

Antibodies are gifted from mother to child

Active

Antibodies are earned by the animals immune system

Horse Average temperature

The coolest 100 degrees

Cattle and Cats Avg Body temp

101.5

Sheeps, Goats, Pigs and Dogs Avg Body Temp

102.0 (The warmest)

Thermal Neutral Zone

The range of environmental temperatures in which the metabolic rate of an animal is minimized, allowing for comfort and efficiency.

Heat stress

qoccurs when environmental temperature exceeds the upper limit of the thermal neutral zone, leading to physiological strain and reduced productivity in animals.

Cold Stress

occurs when environmental temperatures fall below the lower limit of the thermal neutral zone, resulting in decreased performance and health issues in animals.

Shade

Cheapest Cooling method to reduce heat stress by providing a cooler microenvironment for animals.

Evaporative Cooling (water)

or misting systems) best for swine

Refrigeration

The most expensive but highly effective method for cooling livestock environments, using mechanical systems to lower temperatures and maintain animal comfort.

Base Yield Grade

2.0

HCW

Base 600lbs add/subtract 0.4 for every 100lbs over or under

Fat Thickness

Add 0.25 for every 0.1 inch of fat

REA

Base 11 multiple by the amount over so 11.4 multiply 0.4×0.33 to determine ribeye area in square inches.

KPH

Base is 3.5 If over say 5 then subtract by 3.5

Beef Quality Factors

Maturity and Marbeling

Maturity A

9-30 months Eligible for Prime and Choice

Maturity C

42+months Commerical Beef

Break joint

Young lamb

Spoil Joint

Old Sheep

WHat does tha H in HACCP mean

Hazard

What Does the A in HACCP Mean

Analysis

WHat does the first C in HACCP mean

Critical Control Point

What does the second C in HACCP mean

Corrective Action

What does the P mean in HACCP

Procedure

Expected Progency Difference

Predicts offspring performance compared to others

EPD

An EPD is exactly half of the EBV (Breeding Value) because offspring only get 1/2 of their DNA from one parent.

Accuracy:

>0.7 is high confidence; <0.4 is a "best guess" likely to change.

Heritiability

H²

Low heritabliity (slow Progress)

0-0.2

High Heritbaliltiy (Fast Process)

0.4-0.6

Codominance

Both show up (Roan Red and white hairs

Incomplete

They Blend

Sex limited

Both have the genes, only one sex shows it (Milk production)

Sex-Linked

Specifically found on the X or Y chromosomes.

What Disease requires to kill all Cows in a 100 mile radius

Foot And mouth disease

Zoonotic

Diseases that pass from animals to humans.

Brucellosis/Tuberculosis:

why we pasturize milk

Rabies/Ringworm:

Passed through contact

Selection Differential:

The difference between your chosen parent and the herd average (e.g., if the average is 7 and you pick an 11, the differential is 4).
