A

1: 50
1: 20 (single sire)

23
Q

Ideal scan %

A

Hill: 110-120

24
Q

+ve indoor lambing

A
Protect from weather
Low hyperthermia risk for lambs
Close supervision possible
Can lamb early
Pasture recovers
25
-ve indoor
High labour req Incr disease risk Provide feed, water, bed
26
+ve outdoor
Low labour req Decr disease risk Low expenditure Low fixed costs
27
-ve outdoors
``` Incr starvation/hyperthermia risk Less supervision Dystocia losses Later lambing ltd Uses pasture ```
28
Lamb growth rate
300g/day (milk main E source for 1st month)
29
What occurs in early summer
Shearing (reduce fly strike) Parasitic gastroenteritis
30
What is fly strike
Blowfly eggs hatch into larvae in soiled fleece. Damage skin & underlying tissue. Affects production Control w/ sagging, shearing, dips
31
PGE (parasitic gastroenteritis)
Abomasal & intestinal nematode infection. Control w/ wormers, grazing strategies, breeding resilient, bio active forage, good nutrition (high PRO diet - less eggs/larvae shed)
32
What happens in weaning
Lambs: move onto best forage-foggage (silage aftermath) not before 2 mnth Ewes: unproductive/unlikely to lamb nxt yr culled
33
What happens in autumn
``` Scab control - dipping, injections) Liver fluke control Pre-breeding management - flushing Soundness exams of tups Tupping ```
34
What is flushing
Incr nutrition for ewe pre-tupping to incr ovulation rate - incr twinning Not needed if ewes in good condition
35
What happens in spring
Lambing (usually)
36
Country with most sheep in world
China
37
Country with most sheep in EU
UK
38
Where sheep are found in high concs
Mountainous areas, eg Pennines, Lake District
39
What is the stratified system
Hill breed up high Draft ewes (from hill) move to mid height and x with long wool tup to produce 1/2 breeds 1/2 breed ewes x with terminal sire to produce fat lambs
40
What is a draft ewe
Hill ewe that has had a few lambs up high & is moved down when she would struggle with the high conditions for an easier/more managed last few lambing seasons
41
What chemical is very toxic to sheep
Cu
42
What breed is particularly sensitive to Cu
Texel | Muscly sheep particularly
