what is the scale (range) used for Sheep BCS?
1-5
What is the scale (range) for BCS in dairy cattle?
1-5
What is the scale (range) used to score BEEF cattle?
1-9
Define: nutrient requirement
The quantity of nutrient the AVERAGE animal requires for normal function/ goal.
Often a MINIMUM amount.
A crop that is fermented anaerobically by lactic acid
bacteria
Silage
A sheep was scored at a 1, what does this mean? What treatment do we need to provide?
This sheep is extremely thin/ emaciated and needs additional dietary supplementation to meet nutrient requirements and reach a healthy BCS.
If the angle between hooks and pins creates a U (rounded), the score is ____ a 3.
Above
what is the standard score for BEEF cattle?
5
What is the term for the "safety margin"? What is its purpose?
Nutrient Allowance
Protects against average nutrient requirement variations seen between animals.
Hay has what % moisture content?
15-20%
90% of the a herd normally falls within what scores?
2-4
Does BCS consider weight and size to assess if animals are consuming energy above or below their requirement?
NO.
BCS does NOT consider weight and size because they could be different due to breed, mature size and age.
What BCS score is associated with pregnancy rates of 75-90%?
5
What is the equation for Metabolic Body weight?
MBW= BW^0.75
What issues are associated with harvesting on the wet side? (<30% DM)
DAILY DOUBLE: Effluent
What is the optimal range for ensiling?
What structures are you evaluating while scoring sheep BCS?
spinous & transverse process, spine, ribs, loin, tailhead
At what score do you stop scoring at due to malnutrition? (emaciated cow)
2: the cow is severely thin and will be treated similarly and 2 or less
What are the key structures to assess when BC scoring beef cows?
Backbone (spine), ribs, Hooks, Pins, Tailhead, Brisket
What nutrient needs to be monitored in swine to ensure there isn't excess? Why? (I mentioned this in class!)
Copper
Excess copper is toxic for swine. They already receive adequate copper in their diet and more induces toxicity.
What conservation method would you use in humid climates?
Ensiling
Score this sheep: backbone slightly raised/ smooth rounded spine, ribs SMOOTH indentation, moderate fat cover, and tailbones are barely detectable.
3
1 BCS score difference = approximately ______ pounds
75-80 lb
If the last 2-3 ribs on a beef cow are noticeable and the transverse/ spinous processes are identifiable by palpation, what score will the cow receive?
4
What is the estimated maintenance energy for a 800lb dairy cow?
1. lb to kg: 363.2
2. Find MBW: 363.2^0.75
3. 83.197
4. 0.08* 83.197= 6.656
What is the DM % of silage?
40-60%
