Body Condition Scoring of Beef Cattle, Sheep and Goats Scott Morey DVM, MS Tolland, CT
BCS in Beef Cattle • Importance in monitoring herd nutritional status • Varies throughout the year • Ranges from 1(thin) to 9 (obese) • Utilize to manage feeding practices • Prepare animals before “need” • Close link between BCS and many factors https://animalscience.tamu.edu/2017/08/08/some-thoughts-on-body-condition-scoring-of-cows/
Remember: A Beef Cows job is to make a Calf • Strong link between low BCS and… • Reproductive performance/open cows • Failure to cycle • Failure to conceive • Calving interval • Calf vigor at birth http://www.mibeef.org/beefproduction.aspx

Normal Variations in Body Condition • Typical Range is 3 to 7 • Can vary between animal in a herd • Will vary throughout the year • In my opinion, fat is just as bad as thin • One BCS is about 100 lbs. • Ex. BCS 5=1200 lbs., then 6=1300 lbs.
Investigating Variations • Fat Cows: • Not “Working” (lactation, gestation) • Confinement –Pasture vs. Paddock • Over-feeding • Thin Cows • Under-feeding – #1 reason in my opinion (basic math) • Parasitism • Excess work - twin pregnancy, lactation in certain breeds
Financial Implications • Fat Cows: • In general, cows eat 3% of their body weight daily. • Roughly $4-5 per day in CT. • 10 cows @ 1400 lbs. (BCS 6) = 14,000 lbs. • 10 cows @ 1600 lbs. (BCS 8) = 16,000 lbs. • Difference of 2,000 lbs. OR 1.5 cows OR $7.50/day OR $225/month • Thin Cows: • Takes roughly 10 lb. of feed to make 1 lb. weight gain • BCS 3 @ 900 lbs.. Needs to gain 3 scores (300-450 lbs.) • 400 lbs. x 10 lbs. of feed = 4500 lbs. of EXTRA feed • 1500lbs grain + 3000 lbs. roughage = $581 to “catch up”

Optimal Timing • Goal of BCS 5-7 at time of calving • May require increasing or decreasing feed prior to • Expect a drop in BCS from lactation demand post-calving • It’s hard to increase BCS after calving • Goal of BCS 6 or higher at breeding • About 90 days after calving • May be difficult during winter calving • This is when nutritional management is most important • IDEALS WILL VARY WITH DIFFERENT HERDS AND LOCATIONS
Overall • BCS monitoring is a management tool • Fluctuates throughout the year • Use to help manage feed costs • Maintain reproductive efficiency • Prevent disease
BCS Scoring in Sheep • Sheep are hard to assess visually • Wool cover prevents “eyeballing” them most of the time • Scale from 1 to 5 (thin to obese) • Usually 0.5 increments • Age, pregnancy and wool can affect interpretation of BCS • Parasitism is a serious health concern • BCS monitoring can help find “outliers” in a flock • Causes weight loss • Failure to gain (as a flock or individually)
Need To Be Hands On! • It can be obvious to see a 1 or a 5, but you can not do a real assessment of a flock without being hands on. http://www.sheep101.info/201/feedingewes.htmlhttp://www.infonet-biovision.org/AnimalHealth/Sheep-new-animal-welfare-information
Feel the Topline/Lumbar Vertebrae • Palpating 3 things • Spinous processes • Epaxial Muscles • Fat Cover • Each lumbar vertebrae has 3 processes • Dorsal Spinous • Left and right transverse
Stage of Production Optimum BCS Maintenance 2 Breeding 3 Early Gestation 2+ Late Gestation 3 Lambing 3+ Weaning 2 REMEMBER: IDEALS WILL VARY!!! https://www.apsc.vt.edu/content/dam/apsc_vt_edu/extension/sheep/programs/shepherds-symposium/2012/12_symposium_greiner_bcs.pdf
BCS in Goats • Similar in concepts to sheep • Differences • Meat vs. Dairy • Shorter hair coats • Sternum http://www2.luresext.edu/goats/research/bcshowto.html
