Abstract Previous research demonstrated the growth promoting benefits of an essential oil/oligosaccharide blend (EO; Stay Strong, Ralco, Inc.) or encapsulated sodium butyrate (C4; Ultramix GF, Adisseo, fed to neonatal calves. The possibility exists technologies are additive based on individual mechanisms action. objective was evaluate EO and C4 alone combined when Holstein heifer calves raised ...

Sahinduran S. , M. K. Albay: Supplemental Ascorbic Acid and Prevention of Neonatal Calf Diarrhoea. Acta vet. Brno 2004, 73: 221-224. The experiment evaluated the influence of ascorbic acid on the prevention of neonatal calf diarrhoea. Thirty-five Holstein newborn calves were used in the experiment. Ascorbic acid was administered orally to the trial group calves (n = 25) as follows: three times ...

An unexplained haemorrhagic disorder of young calves, Bovine Neonatal Pancytopaenia (BNP), has appeared in Europe since 2007. BNP affected 14 beef calves born between March 2009 and April 2010 in 210-cow Scottish beef herd; only one calf survived. During both calving seasons the cows appeared clinically well and calved normally, giving birth to apparently healthy calves of a good birth weight. ...

Passively acquired antibodies through colostrum will protect calves against etiological agents of neonatal calf diarrhea. Among them enteric diseases due to strains of Enterotoxigenic Escherichia coli (ETEC) are the most commonly occurring form of colibacillosis in newborn calves. Specific antibodies against whole ETEC cells and total immunoglobulin G in dam serum, colostrum and calf serum were...

G-typing of rotavirus strains enables the study of molecular epidemiology and gathering of information to promote disease prevention and control. Rotavirus strains in fecal specimens from neonatal calves in Swedish cattle herds were therefore characterized by using G1 to -4-, G6-, G8-, and G10-specific primers in reverse transcription (RT)-PCR. Fecal samples were collected from one dairy herd (...

The objective of the study was to evaluate the effects of 3 targeted growth rates on adaptive (i.e., antigen-specific) immune responses of preruminant, milk replacer-fed calves. Calves (9.1 +/- 2.4 d of age) were assigned randomly to one of 3 dietary treatments to achieve 3 targeted daily rates of gain [no growth (maintenance) = 0.0 kg/d, low growth = 0.55 kg/d, or high growth = 1.2 kg/d] over ...

Data from calf studies conducted over the past 20 yr has shown that preweaning nutrient intake, from milk or milk replacer, can have profound effects on development of the calf that enhance first lactation and lifetime productivity. Many of the studies show positive but not significant effects of preweaning nutrition on long-term productivity, primarily due to a lack of power, usually due to in...

It has been suggested that United Kingdom recommendations for feeding the neonatal calf (500 g milk replacer (MR)/day; 200-230 g CP/kg milk powder) are inadequate to sustain optimal growth rates in early life. The current study was undertaken with 153 high genetic merit, male and female Holstein-Friesian calves (PIN2000 = £48) born between September and March, with heifers reared and bred to ca...

Effects of growth rate on fat-soluble vitamin and macro- and micromineral concentrations in the circulation of preruminant dairy calves were evaluated. Dietary treatments were designed to achieve 3 targeted rates of gain [no growth (NG)=0.0 kg/d; low growth (LG)=0.55 kg/d; or high growth (HG)=1.2 kg/d] over a 7-wk period. Milk replacer (MR) intakes necessary to achieve these growth rates were e...
