Cow Body Condition Score Estimation with Convolutional Neural Networks

2019 IEEE 4th International Conference on Image, Vision and Computing (ICIVC), 2019
In this paper, we investigate cow body condition score estimation with convolutional neural networks and find that it is difficult for a convolutional neural network classifier to directly discriminate the categories that have very similar appearance in our dataset.

Body Condition Scoring Beef Cows

, 2014
Body condition scoring uses a numeric score to estimate body energy reserves in the cow. Research indicates that there is a strong link between the body condition of a cow and her reproductive performance.

Adjusting weight for body condition score in Angus cows

Journal of Animal Science, 1992
Weight, height, and body condition score data supplied by the American Angus Association were used to determine the effect of body condition score on cow weight and to compute condition score adjustment factors. Single records on 11,301 cows for weight and 7,769 cows for height were collected at or near weaning, at which time a subjective condition ...

Weight necessary to change body condition scores in Angus cows

Journal of Animal Science, 2002
Weights and body condition scores (BCS) were measured and assessed on Angus females (n = 367) over 14 yr (1981 to 1994) to allow calculation of weight adjustments for different BCS. Data were collected at five time periods: prepartum, postpartum, prebreeding, postbreeding, and midgestation.

Invited review: Body condition score and its association with dairy cow productivity, health, and welfare

Journal of Dairy Science, 2009
The body condition score (BCS) of a dairy cow is an assessment of the proportion of body fat that it possesses, and it is recognized by animal scientists and producers as being an important factor in dairy cattle management. The scale used to measure BCS

Body condition score, health, yield and fertility in dairy cows

Veterinary Record, 1997
The effects of body condition score at drying off and after calving and the rate of loss of body condition score during the dry period on the performance of 2162 cows in eight commercial Israeli Holstein herds were evaluated. The relationships between health, fertility and yield and body condition score were examined by using multiple logistic ...

Partition of fat, body composition and body condition score in mature cows

Animal Science, 1984
ABSTRACTBody condition score, assessed subjectively on the live animal, was related to the directly determined body composition of 73 mature, non-pregnant, non-lactating cows of Hereford × Friesian, Blue-Grey, Galloway, Luing and British Friesian genotypes.

Genetic parameters for weight, weight adjusted for body condition score, height, and body condition score in beef cows.

Journal of animal science, 2003
Weight (CW, n = 61,798), weight adjusted for condition score (WA), hip height (CH, n = 56,494), and condition score (CS, n = 61,434) of cows (2 through 8 yr of age) produced by crosses of 22 sire breeds with Angus and Hereford dams in the first four cycles of the Germplasm Evaluation (GPE) Program at the U.S.

Comparison of two methods of assessing dairy cow body condition score

Journal of Dairy Research, 2009
Two body condition scoring systems were compared for assessing body condition of cows at the Scottish Agricultural College's Crichton Royal Farm. The weekly body condition scores (BCS) were collected for a period of 12 weeks (5 September–21 November). Scores were obtained using the primary systems utilized within the UK and USA. The USBCS were obtained

Body Condition Scores in Dairy Cows: Associations with Metabolic and Endocrine Changes in Healthy Dairy Cows

Journal of Veterinary Medicine Series A, 2002
SummaryRelationships between body condition scores (BCS), metabolic profiles and endocrine traits were investigated in 53 healthy Red Holstein cows. Cows were categorized into groups based on BCS ante‐partum (a.p.; >3.25 or ≤ 3.25) and on BCS losses during the first 8 weeks after calving (ΔBCS8 >0.75 or ≤ 0.75).
