Goats and sheep: a weapon against weeds SUSAN SCHOENIANSheep & Goat SpecialistUniversity of Maryland Extensionsschoen@umd.edu – www.sheepandgoat.com
Topics Choosing animals Controlling animals Animal management
Choosing animals Species Breed Sex Age Condition Health
Species Goat Sheep Both
Goats Browsers Top-down grazers Selective grazers Can tolerate secondary compounds Very agile Can reach high-growing forage Will destroy young trees Don’t like to get wet Can be hard to contain Harder to handle
Sheep Intermediate grazers Readily consume grass Prefer forbs (broadleaf weeds) Selective grazers Graze close to the ground Avoid wet areas Easier to handle Easier to contain
Breed Some breeds have different grazing preferences. Larger framed animals will have a higher browsing line. Breeds vary in their  management needs and  tolerance to environmental stresses and disease challenge. There are more differences  among breeds than between breeds. ,[object Object],[object Object]
Age Lambs and kids learn to eat from their dams. Lambs and kids are more likely to try novelty foods. Lambs and kids have higher nutritional requirements. Lambs and kids are less tolerant of environmental  stresses and disease challenges. Older animals are easier to handle and move.
Condition Horns Status  Health
Horns Horned animals are usually more difficult to handle than polled (or disbudded) animals. Horns can get entangled in fences and feeders. Horned animals need more space. Horned animals will dominate polled animals. Should not mix horned and polled animals. Most common breeds of sheep do not have horns.
Status Growth ,[object Object],Early to mid-gestation Late gestation Early lactation Late lactation
Health General appearance Hair coat Body condition Thriftiness Disease status External parasites Internal parasites Hoof health Vaccinations	 Clostridial diseases ,[object Object],[object Object]
Controlling animals Transportation ,[object Object],Handling
Fencing options Permanent Woven wire or net fencing High-tensile, electric Temporary, portable Electric smooth wire Polywire, tape, rope Electric netting
Permanent fencing Traditional net wire		 Physical barrier Off-set wires to keep predators out and livestock away from fence. More expensive High-tensile, electric Psychological (and physcial?) barrier  4 to 8 strands, properly- spaced wires Less expensive
Temporary (portable) fencing Electric netting Electricsmooth, polywire, tape, rope Different configurations and heights Comes in standard size rolls. Physical/physiological barrier Predator proof More expensive 1 to 3 wires Single or multi-wire rolls Step-in posts Least expensive type of fencing Physiological barrier only
Handling options Low-stress Manhandle them Train them Work in harmony with their natural behavior Working pens Chute Restraint Foot bath Push Drag Pull Grab horns ,[object Object]
Halters
Grain as motivationDon’t handle them ,[object Object],[object Object]
