“…These changes reflect the physiological adjustments likely to occur in a newborn animal following transition from the controlled uterine environment to the free-living state. It has been stated that ovine and caprine newborns have high metabolic rates immediately after the birth, which may increase their body temperatures at this time (Vannucchi et al, 2012). The decrease in the RT values observed 24 h after birth may be due to a reduction in heat generation for body temperature maintenance.…”

“…A substantial proportion of postnatal diseases or death could be prevented by good management and by early intervention and by diagnosis and treatment of situations that involve a high-risk newborn. The postnatal period, known as the adaptative period, is a critical life stage that begins at birth and extends until the 30th day of life and that reflects the ability of newborn to complete their maturation with the animal's adaptation to extrauterine life (Piccione et al, 2007;Vannucchi et al, 2012). At birth and during the subsequent days of extrauterine life, the thermoregulatory, cardiovascular, respiratory and homeostatic mechanisms complete newborn maturation (Chniter et al, 2013).…”

Abstract. The effects of time after birth and of twinning on rectal temperature (RT), heart rate (HR), respiratory rate (RR) and body weight (BW) values were evaluated in five singleton Comisana lambs (three males and two females), five singleton Maltese Kids (three males and two females), four couples of twin Comisana lambs (four males and four females) and four couples of twin Maltese kids (four males and four females) during the first month of life. For all kids and lambs, RT, HR, RR and BW were recorded after 1 and 24 h from birth and every 2 days until the 30th day of life. The application of two-way repeated measures analysis of variance (ANOVA) showed a statistically significant effect of time (P < 0.0001) on RT, HR, RR and BW values in all lambs and kids during the first month of life. Any significant effect of twinning (P > 0.05) on all studied parameters was found in lambs, whereas statistically significant differences in BW, RT and HR values (P < 0.01) were found between twin and singleton kids throughout the first month of life. The results obtained in this study make a contribution to the knowledge of homeostatic, cardiorespiratory and thermoregulatory adaptations occurring in singleton lambs and kids and in twin lambs and kids during the first 30 days of life. Our findings indicate that the BW, RT, HR and RR values, whose homeostasis is still evolving in newborn, should be interpreted dynamically as a function of the period of postnatal adaptation and also of twinning.

“…This might promote a certain inaccuracy on the results, despite this technique is well used for dogs (Montesinos & Ardiaca 2013). Studies in other species had been conducted in order to improve the technique (Kilgallon et al 2008, McCain et al 2010, Vannucchi et al 2012, Lewbart et al 2014. However, as discussed earlier, the parameters observed here, and combined with a compensatory response of both groups suggest a less significant effect of these variants to the shown data.…”

Lactated Ringer's solution or 0.9% sodium chloride as fluid therapy in pigeons (Columba livia) submitted to humerus osteosynthesis

et al. 2015

The study aimed to compare the effects of intraosseous infusion of lactated Ringer's and 0.9% sodium chloride solutions on the electrolytes and acid-base balance in pigeons submitted to humerus osteosynthesis. Eighteen pigeons were undergoing to isoflurane anesthesia by an avalvular circuit system. They were randomly assigned into two groups (n=9) receiving lactated Ringer's solution (LR) or 0.9% sodium chloride (SC), in a continuous infusion rate of 20mL/kg/h, by using an intraosseous catheter into the tibiotarsus during 60-minute anesthetic procedure. Heart rate (HR), and respiratory rate (RR) were measured every 10 min. Venous blood samples were collected at 0, 30 and 60 minutes to analyze blood pH, PvCO2, HCO3 -, Na+ and K+. Blood gases and electrolytes showed respiratory acidosis in both groups during induction, under physical restraint. This acidosis was evidenced by a decrease of pH since 0 min, associated with a compensatory response, observed by increasing of HCO3 - concentration, at 30 and 60 min. It was not observed any changes on Na+ and K+ serum concentrations. According to the results, there is no reason for choosing one of the two solutions, and it could be concluded that both fluid therapy solutions do not promote any impact on acid-base balance and electrolyte concentrations in pigeons submitted to humerus osteosynthesis.
