The study was conducted to evaluate the effect of age at weaning and breed on the stress response of calves to weaning and their temperament. At calving, 14 Parda de Montaña calves and 14 Pirenaica calves were randomly assigned to either early weaning (at 90 days) or traditional weaning (at 150 days) treatment. During nursing, calves were allowed to suckle their dams twice a day for 30 min. Aft...

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 effects of feeding and intravenous injections of glucose and VFA on blood ghrelin concentrations were investigated in calves before and after weaning. Eight Holstein bull calves were fed whole milk, allowed free access to solid feeds, and weaned at 7 wk. Measurements were carried out at 2, 4, 6, 9, 11, and 13 wk, at which time jugular blood samples were taken from 4 calves through a cathete...

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 carried out at the Livestock Experiment Station, Bhunikey (Pattoki), District Kasur, Pakistan. Forty exotic cows (20 each of Holstein Friesian and Jersey breed) in their last trimester of pregnancy were randomly selected. These cows were divided into two equal groups. Animals of group-I served as control and were injected with 20 ml sterile normal saline intramuscularly, while ea...

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 (...
