BACKGROUND As older persons in the intensive care unit increasingly require long-term mechanical ventilation, accurate indications of readiness for weaning from ventilatory support are needed to avoid premature extubation. OBJECTIVE To describe temporal changes in pulmonary and systemic variables in older adults receiving long-term mechanical ventilation. METHODS After 3 days of unsuccessfu...

In a series of five 17-d replicate trials, a total of 54 cannulated and 12 noncannulated pigs were used to determine the effects of weaning age (17 d or 24 d) on pH, dry matter percentage, aerobic and anaerobic microflora, lactate, and volatile fatty acid (VFA) concentrations in the jejunum, ileum, and cecum of weanling pigs. At -14 d of age, cannulated pigs were surgically fitted with T-cannul...

A study was conducted to determine if early weaning spring born calves can be an alternative management strategy during drought and if early weaning facilitates rebreeding of young cows. Our objectives were to determine effects of early weaning at the start of breeding on cow body weight, body condition score, and reproductive performance with or without estrous synchronization and AI in two he...

The aim of the study was to investigate effect feed additive “Butaselmevit-plus” on state antioxidant defense system piglets during weaning. experiments were conducted basis LTD “KOSHET” Mukachevo district Zakarpattia region. Two groups formed – control and experimental, in amount 10 individuals each group, selected principle analogs age, breed body weight. Animals fed according norms for this ...

[Purpose] To evaluate pre-extubation variables and check the discriminative validity of age as well as its correlation with weaning failure in elderly patients. [Subjects and Methods] Two hundred thirty-nine consecutive patients (48% female) who were on mechanical ventilation and had undergone orotracheal intubation were divided into four subgroups according to their age: <59 years, 60-69 years...

Genetic parameters were estimated for birth weight and weaning weight from records collected on 1,894 Santa Gertrudis calves (939 bulls, 955 heifers) during the 8-yr period, 1978 through 1985. Variance and covariance components were estimated separately by sex and combined across sexes utilizing mixed-model, least-squares procedures (Henderson's Method 3). The mathematical model assumed for est...

Weaning weight (WW) records of 24,066 Asturiana de los Valles beef cattle, including the progeny of 557 sires and 10,653 dams, were analyzed using a multitrait animal model (MAM) and a random regression model (RRM) in order to estimate the variance components and the breeding value of the animals. Three definitions of WW were used: early weaning (EW) for animals weaned before the age of 180 d; ...

This study aimed to determine the qualitative performance of female Rambon goat (Ettawa Grade x Kacang goat) at post-weaning. reaserch was conducted in January - February 2020 Dusun V Sungai Langka village, Gedong Tataan district, Pesawaran regency, Lampung. The research used a survey method with case Observation on post-weaning aged 4 months 1 year included color head, body, legs, tail, ears, ...

Post-weaning performance of piglets from systems where lactation is disrupted (e.g. from multisuckling systems) is superior to conventionally reared piglets. The objective of this study was to establish whether restricted growth prior to weaning caused by disruption of suckling was an important factor in post-weaning performance and also whether there were related changes in gastro-intestinal d...
