discuss the factors in a ewe that could lead to ketosis. If ewes become affected by ketosis, how is it treated?

A ewe carrying twin or triplets in the last week or two of gestation. It is caused by inadequate nutrition in late gestation. It is treated with glucose.

discuss the nutritional needs of ewes during gestation. Why is proper nutrition in the ewe during this period so critical to lamb performance and survival

During gestation the ewes water intake will increase each month. In the last one third of pregnancy, she requires more protein, energy and dry matter. Poor nutrition affects birth weight, growth and reproductive abilities.

when feeding replacement rams, discuss diet formulation and management strategies to minimize the incidence of urinary calculi.

To minimize urinary calculi it is important to maintain a proper Ca:P ratio. Giving ammonium chloride will help the crystals dissolve if an animal becomes sick

what is the most common cause of death in lambs less than 2 days of age?

most commonly, starvation is the leading cause of death for lambs

describe the ideal environmental conditions that could lead to a severe internal parasite problem in goats. What management techniques besides chemical control can reduce the incidence of internal parasites?

Areas that are moist and warm and lots of nutrition to the parasite. A good example would be in the gut. Some management control would be a good drainage system, clean rested pastures, and no feed on the ground.

what can be done to prevent parasite resistance to dewormers?

Rotating different chemical types used to deworm.

what are the three length categories of wool?

clothing, staple length, french combing

list the four most important traits that affect the value of wool

weight, yield, staple length, average fiber diameter

which is the most accurate?

The micron diameter

what three characteristics determine the character of wool?

color, crimp and condition

Creep feed

Early weaned lambs, fall/winter born lambs, twin/triplet lambs, late season, drought

urinary calculi

Blocking urethra, death

Use ammonium chloride/ sulfate to dissolve crystals by acidifying urine

Management

Good drainage, prevent overstocking, clean rested pastures, no feed on ground, adequate nutrition

Milk fever

Late/early gestation. Sheep get weak/lethargic.higher producing ewes most likely to get mf. Treat with calcium dextrose or calcium glucanate. Hypocalcemia. Supply higher levels of calcium/limestone.
