The objective was to study the effects of weaning in week 5 (W5) vs. 4 (W4), as well liquid (LF) dry feed (DF), on growth performance, disaccharidase activity and nutrient transporter expression after weaning. experiment included 12,923 pigs fed LF or DF pre-weaning period a subpopulation 15 from each group, W4DF, W4LF, W5DF W5LF, which were weighed euthanized five days proximal part small inte...

The aim of the study was presentation the differences in piglets sex proportion in litter and its effect weaning and fattening results. The study was carried out on 133 piglets belonging to 10 litters being progeny of PLW breeding sows and PL boars. Individual piglets growth rate from 1 to 28 day and also during fattening period were recorded. Obtained results were statisticaly analysed includi...

Sodium butyrate (SB) provided orally favours body growth and maturation of the gastrointestinal tract (GIT) in milk-fed pigs. In weaned pigs, conflicting results have been obtained. Therefore, we hypothesised that the effects of SB (3 g/kg DM intake) depend on the period (before v. after weaning) of its oral administration. From the age of 5 d, thirty-two pigs, blocked in quadruplicates within ...

Delirium and transient neurologic dysfunctions (TND) often complicate the postoperative course after surgery for acute type-A aortic dissection (AAD). We evaluated the role of clonidine on neurological outcome and respiratory function in 30 consecutive patients undergoing surgery for AAD. Patients were prospectively randomized to receive either clonidine (0.5 microg/kg bolus, followed by contin...

We evaluated whether a knowledge-based system (KBS) connected to a ventilator in pressure support mode could correctly predict the ability of patients to tolerate total withdrawal from ventilatory support. The KBS was designed to continuously adapt ventilatory assistance to the needs of the patient, to manage a strategy of gradually decreasing ventilatory assistance, and to indicate when the pa...

the objective of this study was to evaluate the effects of weaning age on dry matter intake (dmi), average daily gain (adg), feed efficiency (fe), feed cost (fc) and benefit index (bi) of holstein calves reared under organic farming system. thirty two holstein calves were divided into two treatments: early weaning (ew) vs. late weaning (lw). calves in the both groups were provided with whole mi...

This study was conducted to determine the effect of feeding high milk volumes on the growth rate, health and cross-sucking behaviour in group-fed Jersey calves. Three-day-old heifers (n = 120) in a seasonal calving dairy herd were randomly assigned to one of 6 treatment groups. Three groups received high milk volumes (HMV), consisting of ad libitum milk or milk replacer feeding twice a day, whi...

Feed replacement at weaning plays an important role in the induction of pancreatic maturation. To understand the changes in the exocrine pancreas at weaning and the relation to postweaning problems, we studied the function of the exocrine pancreas and changes of intestinal hemolytic Escherichia coli in four pigs. The pigs were chronically fitted with pancreatic duct catheters and T-shaped cannu...

The effect of shifting calf-weaning age on profiles of energy status (BW, BCS, and rib and rump fat) and reproductive performance of beef cows was evaluated in a 3-yr study. Pregnant and lactating crossbred beef cows (n = 408), mainly of Angus and Hereford breeding, were stratified by age and by sex and BW of their calves and assigned randomly into 2 treatments: weaning at approximately 180 d (...
