Introduction
Body Condition Scoring of Cattle
Introduction:
Body condition scoring (BCS) is a useful management tool for distinguishing differences in ________________________ needs of beef cows in the herd.

This system uses a __________________ ________________ to estimate body __________________ __________________ in the cow.

Research indicates that there is a strong link between the body condition of a cow and her __________________________ performance.

The percentage of open cows, calving interval, and calf vigor at birth are all closely related to the body condition of cows both at calving and during the breeding season.

All these factors play an important role in the _____________________ of a beef cow-calf operation and help determine the percentage of viable calves each year.

Monitoring body condition using the BCS system is an important management tool for assessing production efficiency.

Numerical Scoring System 1-9
Body condition scores are excellent indicators of the nutritional status in beef cows. Ideal live weight varies from cow to cow, whereas ideal body condition (BCS _____) is the same for all cows.
Also, body condition can be measured in the field without gathering or working cattle.
Body condition scores are numbers used to estimate _______________ ________________ in the form of _________ and _____________ of beef cows.

BCS ranges from _____ to______, with a score of 1 being extremely __________ and 9 being very _________________.

Areas such as the _______________, ______________________, ___________, ____________________, ________________, and ______________________ of beef cattle can be used to determine BCS.

Be aware that gut fill due to ____________________ contents or _______________ can change the appearance of moderately fleshy cows, especially over the ribs or in front of the hooks.

________________________ can often make it difficult to correctly evaluate the body condition score of a beef cow or heifer. When the hair on the cow is long, palpating the specific areas of fat deposition is particularly important.

Cows should be palpated over the back, ribs, and over the horizontal processes of the backbone (edge of loin).

"Thin" cows will have a __________________________ feel in these areas than cows with moderate or fat body conditions.

It is important to be aware that the ________________ of beef cow can have a strong influence on where body fat is deposited.
For example, Bos taurus breeds and crossbreds will show a more uniform distribution of fat across the ribs, whereas Bos indicus cattle may have very little fat over the ribs but will deposit fat over the hooks and pin bones.

Body Condition Score: 1
Condition: _______________________
Bone structure of shoulder, ribs, back, hooks, and pins sharp to touch and easily visible. Little evidence of fat deposits or muscling.

Body Condition Score: 2
Condition: _____________________
Little evidence of fat deposits, but some muscling in hindquarters. The spinous processes feel sharp to the touch and are easily seen, with space between them.


Body Condition Score: 3
Condition: ___________
Fat beginning to cover over the loin, back, and foreribs. Backbone still highly visible. Spinous processes can be identified individually by touch and may still be visible. Spaces between the processes are less pronounced.

Body Condition Score: 4
Condition: _______________________
Foreribs not noticeable. The transverse spinous processes can be identified only by palpation to feel rounded rather than sharp. Full muscling in the hindquarters.

Body Condition Score: 5
Condition: _______________________
12th and 13th ribs not visible to the eye unless animal has been shrunk. Transverse spinous processes and spaces between are not noticeable to the eye and can be identified only with firm pressure. Areas on each side of the tail head are fairly well filled, but not rounded.

Body Condition Score: 6
Condition: __________________
Ribs fully covered, not noticeable to the eye. Hindquarters plump and full. Noticeable sponginess to covering of foreribs and each side of tail head.

Body Condition Score: 7
Condition: _______________________
End of spinous processes can only be felt with firm pressure; spaces between can be barely distinguished at all. Abundant fat cover on either side of tail head.

Body Condition Score: 8
Condition: ______________
Animal taking on smooth, blocky appearance; bone structure disappearing from sight. Fat cover thick and spongy.

Body Condition Score: 9
Condition: ____________________
Bone structure not easily seen or felt. Tail head buried in fat. Mobility may actually be impaired by excess amount of fat.

Importance of Body Condition
In order to manage a beef cow-calf operation in the most cost-efficient way, producers must be aware of the body condition of their herd.

Research indicates that the body condition of beef cows is related to many critical aspects of production such as _______________________ , days to ____________ , _____________________________, and ______________ production.

When cows are extremely thin (BCS < 4), they are not only reproductively inefficient, but they are more susceptible to ___________________________ .

Cows at BCS 1 are in a __________________________ situation and need immediate attention.

Cows that are over-conditioned (BCS 8-9) are the most _________________ to maintain. Two-year-olds with BCS 8-9 may encounter ___________________ (calving difficulty) due to the excessive fat in the pelvic area.

Guidelines for Body Condition Scores
On average, most beef cows score in the range of ____ to ____ throughout the year.

A cow is expected to be in optimal body condition (BCS ________ ) before calving.

She may __________ condition after calving and possibly into the breeding season.

She may gain condition and weight as ________________________ approaches (assuming there is adequate forage) and continue gaining fetal weight and any needed body condition in late gestation.

Body condition should be evaluated ________________ days before calving.

By assigning BCS scores at this time, the cows can be sorted for appropriate feeding.

Grouping cows by __________ ___________________ and feeding them accordingly can help each of them reach BCS 5-7 by calving.

Scoring cows 60-90 days before calving allows the producer to evaluate the dry cow nutritional program while allowing enough time prior to calving for "emergency feeding" if needed.

Although body condition should be evaluated at calving, it may be difficult to increase body condition since _______________________ requires most of the ______________________ a cow consumes.

If environmental conditions at the time of calving are mild, cows may be able to reach BCS 5 or 6 by breeding time.

However, this is unlikely to occur when the weather is cold or high quality feeds are limited.

Weight VS Body Condition Score
Live ____________________ should not solely be used as an indicator of nutritional status of beef cows in a herd.

Research indicates that body condition is a more ______________________ indicator of nutritional status than live weight.

Most herds have cows that range in age, _______________________, and muscling, all of which impact the weight of the animals.

Therefore, only using live weight may over- or under-estimate the amount of body fat.

Live weight is also affected greatly by ________________ and ________________ .

Problems with high & low body condition scores

Thin Condition BCS 1- 4 Fat Condition BCS 8-9
1. Failure to cycle 1. Costly to maintain
2. Failure to conceive 2. Increased dystocia
3. Increased calving interval 3. Impaired mobility
4. Increased days to estrus 4. Failure to cycle
5. Decreased calf vigor 5. Failure to conceive

Nutritional Priorities
When nutrient intake fulfills the highest priority requirements, the excess is used to fill lower priority requirements.

Write Down the Nutritional Priorities in order from highest to lowest

1.

2.

3.

4.

5.

6.

When all current requirements are fulfilled, the excess is stored as __________.

During periods of low energy intake, excess external body fat is the first body tissue used to meet nutritional requirements.

When energy is insufficient, fat stores may not be enough to fulfill requirements.

When this happens, ____________________________ (protein) is broken down to satisfy energy demand.

Nutritional Programs Using Body Condition Scores
Since feed costs make up roughly ______% of the cost of a cow-calf operation, different feeding programs can be used to achieve the best reproductive performance without high costs.

Choosing a calving ______________________ that is most compatible with your ___________________ program is the first step in maximizing cow condition and reproduction.

Understand that the changes that occur in body weight and condition are normal in the production cycle of the cow.

A medium-framed beef cow that is open will gain or lose approximately ______________ pounds for each body condition score change.

For example, a medium-framed beef cow with a BCS _____, weighing _________ pounds, will be a BCS _____ and weigh approximately ______________ pounds with a loss of 150-200 pounds and a decrease of two body condition scores.

Moreover, an additional ___________ pounds is typically gained during the last trimester of gestation for fetal growth and uterine development.

Recommendations: ________________ days prepartum to achieve a BCS of ____________ by calving.

Summary
Achieving a BCS of _______ or more before calving and throughout the production cycle is a key to a profitable cow-calf operation.

Maintaining and feeding beef cows to attain a BCS in the optimum moderate range (BCS 5-7) allows beef cows to achieve maximum reproductive performance while feed supplementation costs are held to a minimum.

By sorting and feeding groups based on BCS, the economics of the operation improve.

Producers need to pay attention to stocking rates and pasture quality.

____________________________ and poor forage quality can lead to "thin" cows.
