Changes in the fecal concentrations of cortisol and androgen metabolites in captive male jaguars (Panthera onca) in response to stress BJMBR
Morato,R.G.; Bueno,M.G.; Malmheister,P.; Verreschi,I.T.N.; Barnabe,R.C..
In the present study we determined the efficacy of the measurement of fecal cortisol and androgen metabolite concentrations to monitor adrenal and testicular activity in the jaguar (Panthera onca). Three captive male jaguars were chemically restrained and electroejaculated once or twice within a period of two months. Fecal samples were collected daily for 5 days before and 5 days after the procedure and stored at -20ºC until extraction. Variations in the concentrations of cortisol and androgen metabolites before and after the procedure were determined by solid phase cortisol and testosterone radioimmunoassay and feces dry weight was determined by drying at 37ºC for 24 h under vacuum. On four occasions, fecal cortisol metabolite levels were elevated above...

Effect of dietary carotenoids on reproducers of Amazon River prawn Macrobrachium amazonicum. Part 1: metabolism,morphometric / zootechnical indexes, body composition and gametes. Repositório Alice
COSTA, D. P. da; CASTILHO, C. de L.; SANTOS, U. R. A. dos; GEMAQUE, T. C.; DAMASCENO, L. F.; LIMA, J. de F.; MIRANDA FILHO, K. C..
The inclusion of natural extracts and solution of synthetic astaxan thin in the Macrobrachium amazonicum diet w ere tested to verify their effect on performance, body indexes and total accumulation of astaxanthin in the reproductive tissues and gametes of this crustacean in comparison with newly captured wild animals. The e xperi ment was randomized in blocks (five treatments with three replicates). Four groups were submitted, during 20 days, to diets in recirculation tanks: control diet (CONT); diet containing natural extract of “buriti” (CAR); diet with inclusion of natural “uruc um” extract (BIXN), diet with syntheti c astaxanthin (ASTX) and NATURAL group (not fed with ration). 180 prawns were used, with 60 males (6.08±1.96 g) and 120 females (4.55±1.03...

Establishment of an anesthetic protocol for semen collection by electroejaculation in six-banded armadillos (Euphractus sexcinctus Linnaeus, 1758) Arq. Bras. Med. Vet. Zootec.
Sousa,P.C.; Amorim,R.N.L.; Lima,G.L.; Paiva,A.L.C.; Paula,V.V.; Freitas,C.I.A.; Silva,A.R..
ABSTRACT The aim was to verify the effects of different anesthetic protocols used during electroejaculation (EEJ) in six-banded armadillos (Euphractus sexcinctus). Four sexually matured animals were physically restrained and subjected to semen collection by the EEJ following three treatments: The control group consisted of no use of anesthesia; in the others, the anesthetic combinations xylazine/ketamine/propofol or butorphanol/ ketamine/propofol were administered. For each group, twelve procedures were conducted for EEJ. Semen was evaluated for volume, color, aspect, motility, sperm concentration, morphology, viability, and functional membrane integrity. The highest efficiency (100% ejaculates) was achieved when the control group was used; the...

Use of infrared thermography to evaluate the inflammatory reaction in cat testis after intratesticular injection of 0.9% NaCl or 20% CaCl2 with 1% lidocaine Arq. Bras. Med. Vet. Zootec.
Paranzini,C.S.; Cardoso,G.S.; Souza,A.K.; Perencin,F.M.; Melanda,C.A.A.; Bracarense,A.P.F.R.L.; Martins,M.I.M..
ABSTRACT Due to the doubts and questions about the inflammatory reaction caused by chemical castration, this study aimed to use infrared thermography to detect, evaluate and monitor the inflammatory reaction caused by the intratesticular injection of calcium chloride (CaCl2) 20% with lidocaine 1%. For this, thermographic measurements were taken before (M0), 10 minutes (M1), 1 and 6 hours (M2 and M3), for 7 consecutive days (M4 to M10), at 15 (M11), 30 (M12) and 60 (M13) days after intratesticular injection. Additionally, changes to testicular tissue and effects over spermatogenesis were evaluated by andrological exam before (M0) and 60 days (M13) after intratesticular injection. All cats were orchiectomized at M13, and testicles were submitted to...
