Sheep Production test 3

Animal Day

_ is the amount of forage one animal consumes in one day to maintain weight.

Stocking Density

___ is the number of animals per area at a given moment in time.

Stocking Rate

__ is the number of animals per area over a grazing season.

Overgrazing

______ is when an individual plant is grazed a second time before it has time to fully recover.

Animal Unit

____ is the amount of forage DM that one mature cow weighting 1000 lbs. with a calf at her side will consume in a year.

true

Better grazing management can increase carrying capacity.

false bc Proper grazing management can reduce exposure to parasites.

Pasture management cannot impact parasite load in small ruminants.

true

Excessive grazing reduces leaf area and depletes reserves in the root system, shrinking the roots.

false because If the rest period is to long, forage matures and has a lower nutrient value.

Rest periods need to be as long as possible and have no impact on nutrition available on pastures.

false because Fertility is critical, pH as well as other nutrients are critical for forage production, Manure does not fully meet the needs.

Soil fertility is not a concern for pastures as the manure of the animals provides the proper nutrition for pastures.

true

Research has shown that increasing the protein in the diet can reduce fecal egg counts.

false because There are 3, lamb, yearling mutton, and mutton.

In the US grading standards for sheep, there are 2 classes of meat: Lamb and Mutton.

true

Mutton is not usually graded.

true

Mutton can receive the Choice quality grade.

false because It is the leg score.

The body score is a subjective evaluation of muscling, contributes to attractiveness, and lean yield of the leg of lamb.

break

In sheep in the US the _______ joint is used to determine age at slaughter of lambs and for classifications.

Flank Streaking

As most lamb carcasses are not cut between the 12th and 13th rib, ______________ is used to determine marbling in lambs.

Prime

A lamb carcass that is: thickly muscled throughout; has moderately narrow, slightly f lat rib bones, moderately red and moist and porous break joints, and a slightly dark pink color of inside flank muscle; and has a minimum flank fat streaking of small for young lamb is required to make the ________ grade.

Yield

___ grade is based on adjusted fat thickness and predicts the % boneless, closely trimmed lean yield from the leg, loin, rack, and shoulder.

Polyestrous

For reproduction, sheep are consider seasonally _____________, they have multiple estrus cycles but during a specific time of year.

2/3

In ewe lambs, first estrus is 6 months of age or ______________ of adult body weight

false because shorter grazing exposes the animals to more parasites as they

Grazing height does not have an impact on parasite exposure for sheep

false because it does impact plant diversity and can be used to increase or decrease diversity.

Grazing Management has no impact on plant diversity in your pastures.

true

Drones can be used to monitor differences in pastures through use of different photography methods.

true

Sericea Lespedeza has been shown to reduce parasite loads in animals

Bone

_____ development provides the structure needed for muscle growth.

Fat

The last tissue to develop is___ tissue, it is sued to store excess energy.

Feed

Mineral balance can be impacted by ____ additives provided to the animals.

Environmental

____ factors such as cold, wet, and mud can increase nutritional demands on the animal

Clostridia

Other than parasites the major disease concern in growing lambs is ___, it is usually due to excess grain consumption.

Recovery Period

time it takes for plants to fully recover from grazing

A dry ewe is

0.15

A mature Ewe w/lamb

0.2 AU

0.25 AU

A mature ram

Grazing

is the lead cost feed option and when managed correctly can reduce the overall cost of production

soil health, fertility, and management.

Good forage quality is dependent on
