define enurination

urinate on their front legs and beards; increases the intensity of the bucks odor in order to advertise his fitness

when and where were sheep domesticated

•*dry mountainous areas* of southwest and central Asia •8,000-10,000 years ago

what are 7 qualities of good wool

•absorbs water •generates heat from sunlight •superior insulator •light weight •very elastic •durable and strong •almost inflammable

describe the udder of a dairy goat. be able to label: alveoli, gland cistern, lobules, septum, streak canal, teat cistern

•area of glandular tissue contains lobules and houses the alveoli • gland cistern collects the milk as its released from alveoli •milk enters the teat cistern •milk is released from the mammary gland through the streak canal

differentiate between disbudding and dehorning

•disbudding- removal of horn buds of young kids •dehorning- removal of horns after they have emerged

what are 3 characteristics of wool

•elastic (can be stretched by 30%) •crimp (allows for insulation) •strong (stronger than steel)

differentiate between goat and cow milk

•goat milk *easier to digest* because it has finer & smaller fat droplets •goat milk is lower in *bacterial counts* •goat milk is somewhat *whiter* •*equal fat content* •goats can produce more milk relative to size than cows

differentiate between greased wool and scoured wool

•greased- wool as it is shorn from the sheep •scoured- greased wool after it has been through a cleaning process that removes grease and foreign material

describe how to restrain a goat

•haltered to lead •*straddled at the withers and backed into a corner* with head or *horns held firmly* •do not place on hindquarters
