Flashcards in small ruminants Deck (10):
1

goats

browsers
eat with their heads up
less likely to getparasites

2

sheep

grazers

3

sheep are susceptable to copper toxicity

interacts with olybdenum and forms an insoluble complex. over10:1 leads to toxicity.
when molybdenum is less than1 ppm normalcopper levels are toxic.
selenium supplementaton will increase copper utilization

4

less than 1 Molybdenum

growth: 8-10
gestation: 9-11
lactation: 7-8

5

more than 3 ppm molybdenum

growth: 17-21
gestation: 19-23
lactation: 14-17

6

copper problems

cumulative
trace mineral salts may hve alot
mixed or manufactored lamb feeds will have alot
many no copper salts have copper contamination
more errors with mixed feeds

7

signs of copper toxicty

hematuria
icterus
depression
anorexia
weakness
excessive thirst
hemoglobinemia
hemorrhagic enteritis
suddendeath related to stress
uremia

8

looks like copper toxicity

toxic plants
eperythrozoaa
onin poinson
leptospirosis

9

how to treat copper poisoning

ammonium molybdate and sodium thiosoulface orally per day for 2-3 weeks
keep copper/molybdate ratiobew 6:1 or 8:1, may need extra molybdaate
cu mo complex is formed in gi tract reducing copper absorption

10

toxic liver levels 100-2000 ppm

toxic kidney levels greater than 15 ppm
