The objective of this study was to determine the comparative changes in the monthly blood urea nitrogen (BUN) concentration, total protein (TP) concentration in blood serum and the body condition score of Nguni cows and heifers raised on sweetveld. Twenty-four clinically healthy animals in different parities, namely Parity 1 (n = 5), Parity 2 (n = 5), Parity 3-6 (n = 9) and heifers (n = 5), wer...

the aim of this experiment was evaluating effect of fish oil versus palm oil on mammary gland health and milk production in holstein cows. ten multiparous holstein cows were used from six week before up to 63 days after parturition. feed intake and milk production were recorded daily, milk composition, body weight and body condition score were measured weekly and blood metabolites were determin...
397 holstein dairy cows were used to determine locomotion score, lameness prevalence and its relationship with age of the animal and body condition score (bcs). locomotion score was determined using seven gait properties of animal. the results showed that more than 56% of cows in the herd had no locomotion problems. more than 40% of cows were placed in the group of suspected subclinical lamenes...
Fatty acids in milk are one of the most important components of milk. The aim of this study was to determinate relationships between groups of fatty acids and body condition score change in Czech Fleckvieh cows. Fatty acids were classificated along its length of chain and its origin. A total of 50 Czech Fleckvieh cows with different parity were included to observation. During the first 4 weeks ...
