Levels Of Milk Glycosaminoglycans In Holstein Cows With Clinical And Subclinical Mastitis, Nicolas Caggiano, Elisa Crespi, Gonzalo Fiorini, Emilio De Simone
Turkish Journal of Veterinary & Animal Sciences
Mastitis is an inflammation of the mammary gland whose diagnosis is based on clinical criteria and the determination of inflammatory markers. The disease is mainly caused by bacteria causing intra-mammary infections. The etiological agent/s are detected by milk culture or by molecular biology approaches. However, these methodologies are unpractical for on-farm diagnosis, where rapid decisions must be made when infected animals are detected. For this reason, the levels of glycosaminoglycans (GAGs) in milk were evaluated as a tool for the diagnosis of mastitis. GAGs levels were determined by the dimethylmethylene blue assay (DMMB) method in milk from healthy animals and …

Turkish Journal of Veterinary & Animal Sciences
This research examined the effects of liquid feeds on calf performance, rumen development, rumen cellulolytic bacteria count, and total bacteria diversity. Twenty Holstein bull calves were allocated to 2 groups either fed with milk replacer (MR) or whole milk. Calves fed milk tended to have higher (P = 0.058) average daily weight gain as compared to calves fed with MR during the entire experimental period. Starter mixture intake was not influenced by either milk or milk replacer feeding. Calves fed with milk had higher (P < 0.001) proliferative cells in the rumen papilla. The expressions of MCT1, MCT4, NHE1, NHE3, ACSS1, AceCS2, and ACSM1 genes, which are related to volatile fatty acid absorption, in the dorsal sac of the rumen were similar for calves fed either MR or whole milk. Fibrobacter succinogenes (P = 0.017) and Ruminococcus flavefaciens (P = 0.037) were significantly higher in the rumen of the milkfed calves. Moreover, denaturing gradient gel electrophoresis (DGGE)-derived dendrograms showed noticeable differences in ruminal microbial population between MR-fed and milk-fed calves. In conclusion, feeding calves with whole milk, which contains better quality protein and nutrients, instead of milk replacers, positively affects rumen development, cellulolytic bacteria numbers and total bacteria diversity.

A Study Of Somatic Cell Counts In The Milk Of Holstein-Friesian Cows Managed In Mediterranean Climatic Conditions, Atakan Koç
Turkish Journal of Veterinary & Animal Sciences
Somatic cell counts (SCC) in the milk of Holstein-Friesian (HF) cows were determined by direct microscopic SCC technique. For a two-year period, milk samples were collected monthly from buckets during the morning and evening milkings at 4 different dairy farms. In total, 1,464 SCC readings from 88 HF cows were analyzed by using repeated measures. Herd, lactation month, parity, milking time, and herd interaction effects on SCC were statistically significant (P < 0.05). The average SCC in milk per herd was between 296,483 and 688,811 cells/ml. SCC in milk increased as parity increased. The average SCC in milk from evening milking was about 83,165 cells/ml higher than from morning milking. Improving milking management, reducing stress, providing extra care during the first month of lactation, and milking at a uniform interval will help to decrease SCC in milk and the prevalence of mastitis.
