ABSTRACT The objective of this study was to evaluate the clinical biochemistry behavior of Black-Tufted Marmosets (Callithrix penicillatta) submitted to blood collection without sedation and after general anesthesia with anesthetics isoflurane or sevoflurane. Blood collections were performed on (M1) day before anesthesia by physical restraint, and (M2) after anesthesia. There were four groups: Isoflurane (GI) and Sevoflurane (GS) using an anesthetic box. GIM: isoflurane induction with mask for a shorter period. Control group (GP): physical restraint in both moments. Plasma was separated and frozen to measure clinic biochemistry values. Urea was higher at M2 in groups GI and GP. AST was higher in M2 in GI, GS, and GP and only GI showed an increase in CK in M2. Glucose was higher in M1 in the GI, GS, and GP groups and fructosamine was higher in M2 in the GI. Stress caused by physical restraint can cause biochemical changes and these must be considered when interpreting the exams. Both the inhalational anesthetic isoflurane and sevoflurane did not cause clinically significant changes in clinical biochemistry results.

ABSTRACT This study was performed during the anestrous, involving 140 Akkaraman Kangal ewes whose lambs had died in the neonatal stage due to pneumonia and enteritis. Intravaginal sponge containing progesterone was placed to the animals (Group 1, n = 70) on day 0 and removed after 7 days, following which 263 µg PGF2α and 500 IU eCG were administered to the sheep. Ram introduction was performed for 7 days (days 8-14), starting from the day after the removal of the intravaginal sponge (day 8). The animals in Group 2 (n = 70) were not exposed to any treatment. Ram introduction was performed simultaneously in both the groups. To determine the reproductive response, reproductive parameters such as estrous, pregnancy, multiple pregnancy, and embryonic mortality rates, number of births, number of offspring, and fertility, as well as their economic implications, were compared between groups. Each reproductive parameter exhibited a statistical difference between groups. An economically positive trend was observed in the study group compared with the control group. It was concluded that in case of lamb losses in commercial farms that derive profit from lambing, pregnancy of ewes can be achieved via sexual stimulation without waiting for the next breeding season.
摘要本研究是在麻醉期间进行的，涉及140只Akkaraman-Kangal母羊，它们的羔羊在新生儿阶段因肺炎和肠炎死亡。在第0天将含有孕酮的阴道内海绵放入动物（第1组，n=70）中，并在7天后取出，随后向绵羊施用263µg PGF2α和500 IU eCG。从移除阴道内海绵后的第二天（第8天）开始，进行7天（第8-14天）的公羊引入。第2组中的动物（n=70）没有暴露于任何治疗。两组同时引入公羊。为了确定生殖反应，在各组之间比较生殖参数，如发情、妊娠、多胎妊娠和胚胎死亡率、出生次数、后代数量和生育能力，以及它们的经济影响。各组之间的每个生殖参数都有统计学差异。与对照组相比，研究组在经济上出现了积极的趋势。得出的结论是，如果从产羔中获利的商业农场的羔羊损失，母羊可以通过性刺激怀孕，而无需等待下一个繁殖季节。

ABSTRACT Pacas (Cuniculus paca) are highly hunted animals because of the flavor of their meat, and commercial breeding is recommended. However, this species has a relatively low reproductive rate. This study aimed to collect semen from pacas through electroejaculation and obtain the sperm parameters of this species for the first time. Seven male pacas were used, submitted to an anesthetic protocol before stimulation by an electroejaculator appropriate for the species. The stimulus protocol was performed in three series: series I, 10 stimuli with 1 and 2 V; series II, 10 stimuli with 3 and 4 V; and series III, 10 stimuli with 5 V and interval between series of 2 s. The collected material was evaluated for color, volume, motility, vigor, and concentration. The sperm parameters collected showed a mean volume of 0.43±0.33 mL, concentration of 45.5±42.44×106 sperm/mL, motility of 33.33±32.14%, and mean vigor of 2.6±1.15. In this study, the anesthetic protocol did not seem to favor semen collection by electroejaculation in the pacas. The electrical stimulation protocol was able to stimulate all animals in the study; however, there were few samples with sperm cells and a low rate of motility and vigor in most ejaculates.

ABSTRACT This study was conducted to investigate the effects of dietary propolis alcohol extract supplementation on growth performance, digestibility, intestinal morphometry, and physiologic parameters Nile tilápia (Oreochromis niloticus L.) juveniles. For performance experiment and intestinal morphometry, 120 fish averaging 1.41±0.3g were randomly distributed into 24 tanks (70L each) in a closed recirculation water system with constant aeration and biofilter. The animals were distributed into four treatments using a completely randomized design with six replicates per treatment. The treatments consisted of four pellet feeds with different alcohol propolis concentrations extract (AEP) (0.0, 0.5, 1.0 and 1.5gkg-1). The performance experiment period was conducted for 45 days. For the digestibility experiment, an inert marker in the feed and the adapted Guelph feces collecting system were used. The results showed no differences in the performance parameters, crude protein apparent digestibility and dry matter of the feeds, intestinal morphometry, and physiologic parameters. However, there was an increasing linear effect on the energy digestibility with increasing PAE concentrations in the fish feed. The usage of the propolis extract supplementation levels of 1% is recommended for optimum effect on villus morphometry in Nile tilapia.

ABSTRACT Hyperostotic bones occur in several families of marine teleosts, however there are few reports on its development in fish from Brazilian waters. The present study identified the occurrence of hyperostosis in specimens of Leatherjacket fish Oligoplites saurus, an important commercial species, using radiographic images. Biometric measurements of four specimens were performed and the affected bones were detected in different levels and regions of the skeleton: Supraoccipital, Pterygiophores, Cleithrum, Hemal Spines and Neural Spines. Bones with hyperostosis represented up to 7% of the weight of the eviscerated fish. The pattern found was consistent with previous reports in the literature for other species of the genus Oligoplites, this being the first report of hyperostosis for O. saurus.

ABSTRACT The purpose of this study was to investigate whether intravenous crotalphine produces significant sedation, as well as physiological changes, in healthy standing horses. Six mares, aged 8 years and weighing 415kg underwent three different treatments in a crossover design: TA (acepromazine: 50μg.kg-1), TC (crotalphine: 0.01μg.kg-1) and TX (xylazine: 1000μg.kg-1), intravenously. At various time points over 60 minutes, physiologic variables were recorded: heart rate, respiratory rate, and rectal temperature. The head height from the ground (HHG) was evaluated in centimeters. Data were analyzed using ANOVA followed by Dunnett’s test or Friedman followed by Dunn’s test, under 5% significance. Heart rate decreased significantly at M5 and M10 compared with Mb in TX (28±7, 26±6 and 40±8 beats/minute-1, respectively; p=0.0004). Respiratory rate and rectal temperature did not differ among groups or time points. The HHG significantly decreased in all groups compared with Mb at various time points (p<0.0001). In conclusion, crotalphine did not produce reliable and durable sedation in healthy standing mares and did not influence cardiorespiratory variables in a clinically relevant manner.

ABSTRACT Vasectomy and castration are the most preferred surgical methods to control reproduction in males. While sexual functions are terminated reversibly in vasectomy, they are removed irreversibly in castration. After these processes, changes are observed in hormones and oxidative stress parameters. In this study, we investigated the effects of vasectomy and castration operations on blood follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone, nitric oxide (NO) and malondialdehyde (MDA) levels in rats. As a result of the analysis, it was determined that FSH, LH, NO, and MDA levels increased (p<0.05) and testosterone levels decreased (p<0.05) in the castration group compared to the sham and vasectomy groups. Considering the data obtained from the present study, when the two operations (vasectomy and castration) are compared in rats, which are preferred for the control of reproduction, it is thought that vasectomy is a healthier method because it is reversible, does not affect hormone levels, and does not increase oxidative stress.

ABSTRACT This study aims to analyze the effects of multimodal environmental modification (MEMO) of cats with recurrence of lower urinary tract signs (LUTS). Treatment of FLUTD included pharmacological treatment, dietary management, and multimodal environmental modification approaches. Twenty client-owned indoor-housed cats with recurrence of lower urinary tract signs had been covered in this observation. Diagnosis of lower urinary tract was made primarily based on the cat's clinical signs, results of laboratory parameters, urinalysis and ultrasonographic examination. Cats were divided into two groups as cefovecin (8 mg/kg sc, single time use) + meloxicam (0.1mg/kg q24h, 3 days) + dry food including l-tryptophan and milk protein hydrolysate to dissolve struvite stones (Group 1) and cefovecin + meloxicam + dry food including l-tryptophan and milk protein hydrolysate to dissolve struvite stones + multimodal environmental modification (Group 2). Clinical and urinary parameters are scored as 0, 1, 2, 3 or 4 points on initial, third, seventh days. Scores of clinical parameters were significantly different between (p<0.05) group 2 and group 1 on the third and seventh days and scores of urinary parameters are significantly different between (p<0.05) group 2 than group 1 on the seventh day. Clients who were contacted after 1 year reported that they did not see any clinical signs of urinary tract diseases.

bimaculatus (Hayashi et al ., 2004) and Odontesthes humensis (Pouey et al ., 2012), different authors have demonstrated that food frequency can affect survival. Thus, for juvenile cobias (2.0 g), it was observed that the feeding frequency of eight feeds per day, together with an ad libitum feeding rate, was suitable for improving the final weight of these fish, without causing problems like intraspecific competition or decreased survival.
