❑ Horses
You can use the same procedure with a horse . Weight in kilograms equals the girth in centimetres squared , then multiplied by the length of the horse ( in centimetres ) from the point of the shoulder to the point of the buttock . This number is then divided by 11 900 to give the final result . ❑ Foals Researchers in Chile have come up with a new formula to make it easier to estimate a foal ' s weight . The method requires only one measurement to be taken . The distance around the girth is measured just behind the elbow and 2,54cm behind the highest point of the withers . The measurement is taken just after the foal has exhaled . The formula is G ³ x 90 ( where G = heart girth measurement in metres .)
❑ Cattle A common formula used for cattle relies on measuring in inches – what is known as Schaeffer ' s formula ~ and gives the result in pounds :
2
W = L x G / 300 where , ~ L - Length of the animal from point of shoulder to point of buttocks in inches . ~ G is the chest girth of the animal in inches . The so-called Minnesota formula gives the result in kilograms : W = LxG 2
/ 600 , where , ~ L is the length of the animal from point of shoulder
ANIMAL HUSBANDRY to point of buttocks in inches . ~ G is the chest girth of the animal in inches . When using this formula without an inchmeasuring tape measure simply divide the number of centimetres by 2,54 before entering
Dimension for the weight of a horse the resulting numbers when it is down the girth is into either formula . expanded . When measuring cattle , make sure that the head is up , as
