The aim of this study was to evaluate the effect housing system on behaviour, performance, and health dairy calves. two-year conducted 56 Holstein bull calves (from birth 60 days age) that were placed in individual hutches immediately after their birth. At age 31 days, 28 moved group by four. weighed at birth, 30 age. starter intake recorded once a day. behavioural activities (lying, standing c...

The present study was conducted to study the effect of fortified soymilk as milk replacer on growth performance and feeding economics of Murrah buffalo calves. Twenty four Murrah buffalo calves of (5 days age) were randomly distributed to four dietary treatment groups (T1, T2, T3 and T4). T1 was control group in which calves were reared on buffalo milk only. In T2 and T3 groups calves were fed ...

A double-blind, placebo-controlled clinical trial of a homeopathic treatment of neonatal calf diarrhoea was performed using 44 calves in 12 dairy herds. Calves with spontaneously derived diarrhoea were treated with either the homeopathic remedy Podophyllum (D30) (n = 24) or a placebo (n = 20). No clinically or statistically significant difference between the 2 groups was demonstrated. Calves tr...

The aim of the study was to explain whether or not the time of ovarian cyst (OC) formation had an influence on reproductive performance in dairy cows. Eighty cows with OC (group A first OC diagnosis < 42 d postpartum; group B first OC diagnosis > 42 d postpartum) were compared with 80 control cows without OC matching in lactation number and calving date. Milk yield was higher in OC cows compare...

The objective of the current study was to examine whether step-down (STP) milk feeding method together with forage provision would improve performance, rumen fermentation, nutrient digestibility, blood metabolites, and structural growth of calves. Holstein bull calves ( = 40) were randomly assigned to 1 of 4 treatments in a completely randomized design with a 2 × 2 factorial arrangement. Treatm...

The decline of dairy cattle fertility worldwide remains a major concern, with conception rates to first service commonly below 40%. The length and severity of negative energy balance postpartum are unfavorably correlated with fertility, suggesting that the length and severity of negative energy balance and fertility are linked via several hormones or metabolites. These compounds therefore have ...

Antimicrobial resistant (AMR) bacteria are increasing threats for human and veterinary medicine. Faecal Escherichia coli (E. coli) from preweaned dairy calves is often resistant to multiple antimicrobials and calves may therefore serve as reservoirs for these bacteria and their resistance genes. This thesis investigated the prevalence, risk factors, and spread of resistant E. coli on Swedish da...

in order to study of effects of sodium bicarbonate on lameness occurrence and the performance of feedlot cattle, 100 holstein bull calves (251.75 ± 5.75) were used in a completely randomized design. calves were group fed a similar basal diet during 42 days experimental period. used treatments included 1) control treatment without feed additive, and 2) experimental diet that calves consumed 50 g...
