title: [Age at puberty and reproductive characteristics of F1 Holstein x Gyr crossbred heifers with divergent phenotypes for residual feed intake]

description: ABSTRACT The relationship between nutritional efficiency and age and weight at puberty and reproductive traits was studied in 35 F1 Holstein x Gyr heifers, in trials using residual food consumption (CAR) in the post-weaning (PW) and post-pubertal (PP) periods. PD heifers (P&lt;0.0001) and PP (P&lt;0.001) were classified as high, intermediate and low efficiencies and presented CAR of -0.259 -0.014 and 0.346kg/day and -0.848 -0.096 and 0.842kg/day, respectively. PD heifers differed (P&lt;0.05) in age at puberty between high, intermediate and low efficiencies, on average, at 339.7, 346.4 and 315.3 days, respectively. The weight at puberty of PD heifers with high, intermediate and low efficiencies were, on average, 321±28.1kg and did not differ (P&gt;0.05) between CAR. No correlation was found between follicular diameter, follicle growth rate, number of follicular waves in the estrous cycle and pregnancy rate at 1st AI with the CARPD or CARPP. F1HG heifers selected for CAR with low efficiency can be aged at puberty 10 days longer when compared to high-efficiency heifers for CAR. These results did not show that heifers selected for high or low food efficiency, using CAR, had negative impact on the reproductive characteristics evaluated.

title: [Reproductive potential of Nelore bulls evaluated by andrological parameters and sexual behavior. Classification by points - a new proposition]

description: ABSTRACT This study aimed to compare variations of andrological and behavioral parameters from Nelore bulls of different ages, to calculate their reproductive potential (RP) and propose a new classification table by points, considering current averages in each reproductive trait studied. Data were collected from 6162 breeding soundness examinations of Nelore bulls aged between 12 and 80 months, under natural mating. According to andrological parameters, regardless of the libido test, the number of bulls classified as approved was 88.9% (n= 5480), being 51.6% considered as excellent (n= 2827), 41.2% very good (n= 2257) and 7.2% considered as good (n= 394). Among the animals considered as questionable (n= 682; 11.1%), 79.6% were classified as temporarily reproved (n= 542) and 20.4% (n= 139) as discarded animals. The number of bulls classified as excellent decreased to 752 (12.2%) when sexual behavior data were included to define their RP. It was concluded that the use of tables for andrological classification by points with technical updates improves the reproductive selection of Nelore bulls. The libido test is an important tool for RP determination which provides better utilization of the sires.

title: Hepatitis E virus infection in buffaloes in South China

description: ABSTRACT Hepatitis E virus (HEV) infection is an important global public health issue. HEV infections are recognized as a zoonotic disease. Swine are believed to be the main reservoir of HEV. Recently, yaks, cows, and yellow cattle have been reported as new reservoirs of HEV. However, whether other species of cattle and buffaloes are sensitive to HEV infection is unknown. To investigate the prevalence of HEV infection in buffaloes, enzyme-linked immunosorbent assay (ELISA) and reverse transcription-nested polymerase chain reaction (RT-nPCR) were performed. Only one buffalo was positive to anti-HEV IgM antibody (1/106, 0.94%), and none were positive for anti-HEV IgG antibody. To our surprise, five serum (5/106, 4.72%) and three milk samples (3/40, 7.50%) from buffaloes were positive to HEV RNA. All strains of HEV isolated from buffaloes belong to genotype 4. Results indicate that buffaloes may be a new reservoir of HEV.

title: [Oral and rectal microbiota of callitrichids (Callithrix sp.) in an anthropized area of the Atlantic Forest in Rio de Janeiro, Brazil]

description: ABSTRACT Proximity of nonhuman primates (NHP) to humans can be considered a risk factor for transmission of pathogens between these two populations. This study investigated the oral and rectal aerobic bacterial microbiota of marmosets in an anthropized area of the Atlantic Forest located in Rio de Janeiro, Brazil, and performed phenotypic tests for detection of multidrug-resistant bacteria. Twenty-one samples (14 from the oral cavity and seven from the rectum) were collected from 14 Callithrix sp. captured in two sites of the forest near human dwellings. The most frequent species identified from the oral cavity swabs were Klebsiella oxytoca (50.0%), K. pneumoniae (28.6%), Kluyvera ascorbata (21.4%) and Stenotrophomonas maltophilia (21.4%), whereas the species most commonly identified from the rectum swabs were K. pneumoniae (85.7%), Enterobacter spp. (42.9%) and Escherichia coli (28.6%). All isolates of family Enterobacteriaceae showed no extended spectrum β-lactamase production by disk-diffusion and automated detection tests. In the search for carbapenem-resistant enterobacteriaceae these isolates presented no resistance to the imipenem, meropenem and ertapenem antibiotics. The isolate of Staphylococcus aureus was susceptible to oxacillin and the isolate of Enterococcus was susceptible to vancomycin. All isolated bacteria showed zoonotic potential, thus posing a risk to species conservation and public health.

title: [Testicular ultrasonography in the doppler / spectral color mode and andrological evaluation of stallions treated with human corionic gonadotrofin (hCG) in different seasons of the year]

description: ABSTRACT Four stallions were used in January, April, July and October 2016 in two protocols: GI (n=4; 5ml saline, iv) and GII (n=4; 5000 hCG, iv), and these protocols were subdivided into cycles (C1 and C2) following the cross over scheme, as follows: CI=animal 1 (GI) and 2 (GII) evaluated on days D1, D3 and D5 and animal 3 (GI) and 4 (GII) at D 2, D 4 and D 6; CII=animal 1 (GII) and 2 (GI) at D1, D3, D5 and animal 3 (GII) and 4 (GI) at D2, D4 and D6. Treatment was performed on D1 and D2 of each cycle and testicular ultrasound in color Doppler and spectral Doppler mode, one hour before each semen collection and immediately after. We evaluated: Flehmen's reflex number, mounts without erection, start of the mount, reaction time to erection and total mount and seminal quality analyzes. Statistically, the Chi-square and ANOVA tests were used. There were no statistical differences (P&gt;0.05) between the analyzed parameters. It was concluded that a single dose of 5000IU hCG in stallions did not cause significant changes in the parameters evaluated in different seasons of the year.

title: [Standardization of the Sperm Class Analyzer® (SCA®) for the evaluation of cryopreserved equine sperm]

description: ABSTRACT The objective of the first experiment was to evaluate the effect of 25, 30 and 50Hz frame acquisition rate on equine cryopreserved sperm. All frame acquisition rates tested were adequate to capture the sperm movement (P&gt;0.05). The aim of the second experiment was to evaluate the effect of chambers, slide-coverslip, Leja®10 and 20 on sperm movement. The use of slide-coverslip was superior to maintain LIN and WOB (P&lt;0.05). The aim of the third experiment was to evaluate the effect of 25, 50 and 100x106 sperm/mL concentration on sperm movement. Concentrations of 25 and 50x106 sperm/mL were greater than 100x106 to preserve LIN, STR and BCF and did not adversely affect motility (P&lt;0.05). The aim of the fourth experiment was to evaluate the effect of BotuCrio®, BotuSêmen®, TALP sperm and physiological solution on sperm movement. BotuCrio® was superior among other extenders in preserving BCF and hyperactive (P&lt;0.05). It is concluded that the use of the frame acquisition rate between 25 and 50 Hz; the deposition of semen between slide and coverslip and new dilution in the freezing extender to 25-50x106 of sperm/mL is ideal to reliably evaluate cryopreserved equine semen by SCA®.

title: [Mineral concentrations in the keratinized tissue on the feet of young Crioulo horses at different stages of growth]

description: ABSTRACT The aim of this study was to evaluate the mineral profile of Ca, Cu and Zn in the hoof horny capsule at pre and post-weaning and its association with pigmentation, gender and age range of Crioulo foals raised in native pastures in RS. Samples were collected from the epidermis of the Crioulo foal's hoof at two times, 41 pre and 28 post-weaning. The contents of Ca, Cu, Zn Varied in the fetal hoof ( 571.0±139.4, 14.5±7.6 and 130.0±30.5mg/kg, respectively, P&lt;0.05) and definitive (653.0±169.2, 33.8±11.5 and 69.3±36.8mg/kg, respectively, P&lt;0.05), in the pre (620.0±184, 17.2±21.2 and103.0±75.5mg/kg, respectively, P&lt;0.05) and post-weaning (517.5±181, 0.1 and 79.0±41.7mg/kg, respectively, P&lt;0.05).There was a positive association (P&lt;0.05) with a preweaning age for Ca (r=0.5) and Cu (r=0.57) and negative for Zn (r=-0.69, P&lt;0.05). In the post weaning there was a positive association (P&lt;0.05) for Ca (r=0.36) and Zn (r=0.64) and negative for Cu (r=-0.39; P&lt;0.05). Neither pigmentation nor gender affected the mineral profile. It is concluded that there are differences in Ca, Cu, Zn concentrations in the epidermis of foals of the crioulo breed at the pre and post weaning, regardless of pigmentation and sex, where Ca and Cu concentrations increase with age, while Zn concentrations decrease.

title: Acoustic Radiation Force Impulse (ARFI) elastography imaging of equine distal forelimb flexor structures

description: ABSTRACT This study set out to determine normal values for acoustic radiation force impulse (ARFI) elastography of the superficial digital flexor tendon, deep digital flexor tendon, accessory ligament of the deep digital flexor tendon and suspensory ligament in horses. Twenty-four horses were submitted to conventional sonographic assessment and elastography imaging (quantitative ARFI method) of distal forelimb tendons and ligaments at nine anatomical regions. Elastograms depicted tendons and ligaments in orange to red tones consistent with greater stiffness. Shear wave velocity was higher in the longitudinal compared to the cross-sectional plane but did not differ significantly between the left and right forelimbs. The suspensory ligament was stiffer compared to remaining structures in the cross-sectional plane. Ligaments were stiffer than tendons and the deep digital flexor tendon was stiffer than the superficial digital flexor tendon in the longitudinal plane. Target structures were stiffer in male compared to female horses and stiffness tended to increase with age. ARFI elastography proved to be a feasible and reproducible imaging modality for assessment of distal forelimb tendons and ligaments in horses. Qualitative features derived from stiffness quantification in these structures can be applied to horses with musculoskeletal disorders, as well as to other animal species.

title: [Frequency of non Tumor Skin Diseases in Dogs in the City of João Pessoa, Paraíba, Brazil (2014-2016)]

description: ABSTRACT Faced with the lack of studies on the frequency of dermatopathies that affect dogs by geographical region in Brazil, the present study aimed to evaluate the frequency of dermatopathies that affect the canine species in the metropolitan region of João Pessoa, Paraíba, Brazil. Data was collected from dogs that underwent dermatological care from September 2014 to December 2016. In addition to the clinical and dermatological examinations, dogs underwent complementary exams, such as cytological, skin scraping, parasitological skin examination, trichogram, bacteriological, mycological, histopathological and/or polymerase chain reaction. During the study period, 1,083 dogs were examined, in which 18.65% (202 /1,083) had some form of non-tumoral dermatopathy. Of the 202 dogs affected, 51.49% (104/202) were males and 48.51% (98/202) females. Of these 202 dogs, thirteen had two diagnoses, totaling 215 dermatopathies. 62.87% (127/202) of the affected dogs were purebred and 37.13% (75/202) were without a defined breed (WDB). The most frequently observed lesions were alopecia, hypotric, macular, erosive and ulcerative, placoid, erythematous areas, as well as comedones, collaretes and seborrhoea. The parasitic dermatopathies were the most frequent (35.35%; 76/215), followed by bacterial dermatopathies (24,19%; 52/215), allergic dermatopathies (20,00%; 43/215), dermatomycosis (17,21%; 37/215), dermatopathies for other causes (2,32%; 5/215) and autoimmune dermatopathies (0.93%; 2/215). Clinical and dermatological examination, including a detailed anamnesis, accurate clinical history and associated complementary exams are important tools for the diagnosis of dermatopathies in dogs. Available literature present some studies with canine dermatopathies frequencies superior to that obtained in the present study; however, the number of animals examined was smaller. In this survey, it was possible to establish the primary and secondary diagnoses in 100.0% of the non-tumoral dermatopathies in dogs, results higher than in previous studies. Probably, the frequency of canine dermatopathies in this region is higher than that observed, thus requiring additional studies with greater sampling.
