Subdermal Fat Determined by Ultrasound and Electrical Conductivity, and Its Relationship to Body Condition Score of Dairy Cows
Body condition score (BCS), a very useful field tool for estimation of changes in body tissue reserves is time consuming and subjective. The relationship between body condition score and subdermal fat (SFAT) was determined biweekly as potential for development of a low cost, portable digital …

Breeding for robustness in maternal sheep.
A favourable phenotypic relationship between ewe body condition and reproduction has been well reported in literature with producers managing ewe condition to improve reproductive performance. This thesis explores the genetic variation of ewe body composition across her production life and the …

The effect of overfeeding and obesity on canine adipose tissue and skeletal muscle transcriptomes
… were randomized to ad libitum (n=5) feeding or body weight maintenance (n=4). Subcutaneous adipose tissue biopsy, skeletal muscle biopsy and blood samples were collected, and dual x-ray absorptiometry measurements were taken at 0, 4, 8, 12, and 24 wk of feeding. Ad libitum feeding increased …

Grazing and Feeding Management of Lactating Dairy Cows
… were to compare milk production and composition, body weight change and body condition score, and to determine time patterns of grazing between cows supplemented with different forms and amounts of corn. Also rumen fermentation parameters were measured in cows supplemented with two different types …

Effects of fermenten during the dry and early lactation periods of dairy cows
… weeks 2 through 6. Intake of NDF was below 1% of body weight up to 4 weeks postpartum for all groups. Milk yield was significantly (P < 0.05) depressed by Fermenten (6.50 and 5.95 kg/d for low and high levels, respectively). Milk fat and protein percentages were not affected by diets. Body weight …
