Small Ruminant Nutrition: Sheep Flashcards
6 Urinary Calculli (UC) Preventions
1) Maintain Ca:P -> Ideally 2:1
2) Continuous supply of clean, cool water
3) Check for frozen pipes
4) Adequate water space for all animals
5) Addition of salt or trace mineral salt -> Enhance water intake
6) Addition of 0.5% ammonium chloride to the ration -> Acidify urine
Enterotoxemia Prevention
Vaccination is possible

2) Off-feed
3) “Humped up” appearance
4) Abdomen is often distended, especially with bladder rupture
3 Rectal Prolapse (RP) Preventions
1) Adequate genetics
2) Do not use prolapsed ewe lambs as replacements
3) Adequate feeding -> avoid risk factors
What 2 vitamins are critical and may need supplementation?
Vitamin A and D
What is the major practice in ram feeding?
Mature rams can be maintained on pasture
Supplement with grain/concentrate feeding 30-45 days prior to the breeding seasion
