One of these species is the red-winged-tinamou (Rhynchotus rufescens), that has potential for production in captivity. The aim of the study was to determine genetic microsatellite polymorphisms in this species and other tinamous species. Sixteen microsatellite primer pairs were developed for the red-winged-tinamou from a genomic library enriched with microsatellites. In order to verify the cross amplification for the tinamous species we used 10 pairs of primers designed for ostriches (Struthio camelus) and 10 pairs developed for Tinamus major. From the 16 loci developed for red-winged-tinamou, 8 amplified in this species and only five amplified in other Tinamous. Genotyping was performed on 26 samples and estimates related to the percentage of polymorphic loci (50%), average number of alleles per locus (5.75), polymorphic information content (average 0.62) and expected genetic diversity (0.69). In order to test the transferability of the primer pairs developed for T. major, only one had a specific amplification in partridges, with observed rates of crossamplification of 100 and 70% for macuco (Tinamus solitarius) and the azulona (Tinamus tao), respectively. The amplifications in other tinamous were restricted to five microsatellite loci.

Assessment of ventricular morphology using echocardiography in Ornate tinamous (Nothoprocta ornata) and domestic chickens (Gallus domesticus)

Backlund, Emma January 2014 (has links)
The Ornate Tinamou (Nothoprocta ornata), an ancient bird, has adapted to life at high altitude (>2.400 m.a.s.l) for a longer period than the domestic chicken (Gallus domesticus), which came to South America with the Spanish conquerors. Ornate tinamous have a smaller heart in relation to body size than domestic chickens. This study was made to evaluate heart morphometric measurements comparing Ornate Tinamou and domestic chicken using echocardiography measurements to determine wall thickness and chamber size and to evaluate whether it can retrieve measurements consistent with previous results on dissected hearts. I was also interested in evaluating potential adaptations of the Ornate Tinamou to life in hypoxic environments by exposing the heart to positive inotropic stimulation. The results were compared with those previously obtained on dissected hearts. The results showed that the chamber size of the domestic chicken was significantly larger than in Ornate Tinamou, both in conscious and anesthetized birds. Injection of 1µg/kg isoproterenol caused domestic chickens’ systolic chamber size to decrease significantly and fractional shortening to increase significantly. The same changes were seen in the Ornate Tinamou but they were not significant. In conclusion, this study confirms that echocardiography is a valid method for retrieving cardiac measurements without euthanizing animals, opening for the possibility of taking several measurements at different ages.

Cardiorespiratory responses upon increased metabolism in the Ornate Tinamou, Nothoprocta ornata

Gasparini, Isabella January 2012 (has links)
The Bolivian Ornate Tinamou, Nothoprocta ornata, lives higher than 3300 m above sea level and must constantly deal with a restricted availability of atmospheric oxygen, i.e., chronic hypoxia. Interestingly enough, the Ornate Tinamou has a small heart to body ratio, which implies a reduced ability in transporting oxygenated blood to the tissues. In order to increase knowledge about the cardiorespiratory response of the Ornate Tinamou, heart rate (HR) and ventilation frequency (VR) were monitored during resting at 25 °C. The values were compared with those obtained in conditions known to elevate metabolism, i.e., lowered temperature and graded exercise. This was later compared with domestic chickens, Gallus gallus. Results showed a significant increase in HR at 4 °C, 305 ±42 bpm in the Ornate Tinamou when compared with HR at 25°C, 241± 48 bpm (330 ±42bpm and 239 ±32bpm in chicken). A significant increase in VR was only observed in chicken. As expected, with a progressive increase in running speed, a significant increase in HR in both species was observed. At 1,5 km h-1, HR in the Ornate Tinamou was 327 ±5,6 bpm and 342 ±8,5 in chicken. At 3,0 km h -1 HR was 383 ±15 bpm and 404 ±7,9, respectively. However, HR was not significantly higher in the Ornate Tinamou than in chicken, indicating that there must be other physiological adaptations involved in the sufficient oxygen delivery to tissues, e.g. a high blood oxygen affinity or a preference for anaerobic metabolism due to living in a chronic hypoxic environment.

Heart and ventilation rate changes during tonic immobility in Ornate Tinamou (Nothoprocta ornata) and High Andean chicken (Gallus gallus) compared to Chilean Tinamou (Nothoprocta perdicaria)

Greder, Cecilia Alexis January 2015 (has links)
Animals can show different responses to fear for example by playing dead when there is no possibility to escape. This response is called tonic immobility (TI) and is a well-established test of fear to evaluate fearfulness. Long durations of TI are generally considered as high levels of fearfulness. Physiological changes observed during tonic immobility suggest that there are changes in the autonomic nervous system (ANS) strongly involved in this process. The main objective for this study was to analyse duration of tonic immobility and heart and ventilation rate during tonic immobility in three different species; domesticated High Andean chickens (Gallus gallus), wild-caught Ornate Tinamous (Nothoprocta ornata) and Chilean Tinamous born in captivity (Nothoprocta perdicaria). In this study needle electrodes were used to measure heart and ventilation rate. The time following induction of tonic immobility (i.e. after holding the bird on its back for 15 s) was characterized by a large increase in heart and ventilation rate. During tonic immobility a progressive decrease in heart and ventilation rate was observed in all species, significant in all cases except for heart rate between start and end of TI in chickens. The duration of TI was significantly longer in Ornate Tinamou compared to Chilean Tinamou and chickens. The same was observed in latency to first head movement. TI is probably controlled by the autonomic nervous system, but a heart rate variability analysis has to be done in order to determine the different relative contributions of the sympathetic and parasympathetic systems in these species.

One time per week, during three consecutives weeks, mensurations of tonic immobility response were made in the morning.

Previous informations about female egg production e male egg fertilization, during 2002-2003 breeding season were used to bird classification by productive performance in captivity. None of effects tested to corticosterone secretion was significative in any sex. Although in a short time period, 30 days approximately, prolactin concentration significative reduced in blood circulation, where males declined from 5.77 to 3.95 ng/mL, and females declined from 6.03 to 4.44 ng/mL. No correlation was find significative (P>0.05) among any evaluated characteristics, for both sexes. Tonic immoblility response was not a stress determination to partridges raised in captivity.
