Body Condition Scoring

By An Peischel ©2020 (Fourth in a series)

Body Condition Scoring (BCS) is an important monitoring criteria when utilizing goats for land enhancement (restoration, re- juvenation, weed abatement, fire mitigation, etc.). Scoring will initiate herd management decisions focused on production options to improve performance (physiological status of the individuals and the mob), limit the health problems associated with improper nutrition and in- crease profits by al- lowing selective browsing/grazing based upon the quality and quantity of vegetation re- quired by the goats. All of the above total a decrease in production costs. When using

goats in a “working or production” situ- ation, BCS is a measure of body energy re- serves and a change in body condition will reflect a shift in energy balance. The nu- trition levels required for performance have to be matched to the nutritional require- ments of the goats to attain the desired out- come. Forage and browse resources need to be used efficiently/effectively to sustain biodiversity of successional vegetation communities. The environment, climate and topography will also affect the body con- dition of the goats as will reproductive per- formance.

When using the goats in a breeding program, BCS will be a critical monitoring tool to use as a measure for reproductive performance. A higher body condition at kidding and early lactation will increase the chances of re-cycling, increase the ovu- lation rate and conception in the early part of the breeding season with less breeding days, therefore concentrating the kidding season (advantageous to niche and direct marketing).

If adequate energy is available for mo- bilization at parturition, milk production will be higher and maintained longer. Thin does will likely be late kidders, have de- layed recycling and breeding, and an in- creased probability of abortion. Should they kid, they will have less kids, weaker kids

Research has shown that visual ap- praisal can accurately measure body con- dition. For the most consistent results, palpating along with visual assessment will help measure the adequacy of the nutritional program by evaluating the body reserves. Goats have very little subcutaneous fat. Fat is stored in the omentum and perirenal tis- sues. Body condition will measure the lipid and protein reserves that will be available to use in late gestation, early lactation, dur- ing environmental adversity, etc. It will contribute to making decisions faster about changing a nutrition regime be- cause if one lingers, high production losses and loss of income are possible. It can be very costly to regain body status, therefore

avoid extreme fluctuations in body con- dition scores.

Body weight is a function of breed, body conformation, frame size and mature size, stage of gestation and stage of lacta- tion. The frame, at a point in physiological time, will remain constant but weight will change based on deposition of fat and mus- cle. Both depend on the nutritional and physiological status of the goat. Do not in- clude the fetus or associated fluids when evaluating weight changes. Be careful not to cull on BCS at weaning as there is a neg- ative relationship between body condition and milkability.

By physically palpating and feeling the goat, at both the lumbar and sternal areas, you will develop your “eye” for body
