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.

Clostridium difficile was isolated for the first time in 1935 from fecal samples of infants, although it was not until 1978 that its pathogenicity started to be considered, when it was shown to cause antibiotic-associated diarrhea and pseudomembranous colitis. In this study, it was aimed to determine the virulence and antibiotic resistance profiles of C. dificile in young ruminants with diarrhea and chickens fed on the farm. A total of 200 fecal samples (50 from calves, 50 from lambs and 50 from kid goats with neonatal diarrhea, as well as 50 cloacal swab samples taken from chickens) were taken and …
