Introduction: Goats are selected browsing and selective ruminants, in natural conditions they use up to once hours a day for food consumption. The objective of this study was to evaluate the ingestive behavior and other diurnal behaviors in adult female goats. Methodology: Twelve animals were evaluated under a grazing system with the presence of native trees scat-tered in the low tropics, without introduced grasses and with a supplementation composed of cut grasses and canoe concentrate within the paddock. The observation of the behaviors was carried out for twelve hours a day and a frequency of five in three days, with which 876 observations were obtained per day and 2628 observa-tions in total, climatic variables were taken into account. The information was processed using the Microsoft Excel program and a multiple correspondence analysis was made, using the R statistical package. Results: The consumption behavior in grazing was presented with a higher frequency during the day (26.4 %), decreasing among the 6:00 a.m. to 9:00 a.m., where high precipitation was evidenced and at 11:00 and 16:00 by canoe supplementation. The browsing behavior was presented in 8.95%, with less frequency in the hours between 9:00 a.m. to 2:00 p.m. Quiet and rumination behavior in the lateral ulna position represented 20.4% and 11.5% respectively, both observed throughout the day. Behaviors such as sleeping, drinking and consuming salt, presented very low frequencies. Conclusions: Goats present a constant ingestive behavior during the hours of the day evaluated.

To assure the quality of work with laboratory animals, it is essential to standardize their breeding and mainte-nance processes. The ISO 9001:2015 standard meets the requirements that certify the Quality Management Systems of an organization. The work focuses primarily on the establishment and evaluation of documented information of the processes referred to in requirement 7.5 of ISO 9001: 2015; this regulatory requirement is part of a management system that focuses on customer satisfaction with respect to meeting their needs. A descriptive and exploratory research was conducted. An instrument (survey) was designed where informa-tion was collected on the use of documentation in production and experimental processes. 22 conventional bioterias registered in the Asociación Venezolana para la Ciencia de Animales de Laboratorio (avecal) were studied. The instrument was sent via email to the Heads of each one of the Bioterias. Data were collected and tabulated according to the variables investigated. It was evidenced that 81.8% of these bioterias do not have documents that allow a control and monitoring of their processes. Likewise, those responsible are unaware of the national legal framework, such as the Ley Orgánica del Sistema Venezolano para la Calidad, Normas Generales de Control Interno de la Contraloría General de la República and the ISO 9001:2015. The design of a methodological guide is recommended, so that national bioterias prepare their documents following clause 7.5 of the ISO 9001: 2015 standard to improve the efficiency of their processes.

Case report study where the syndrome of persistence of the Mullerian ducts in male canines of the Schnauzer breed is analyzed, characterizing the symptomatology associated with the presence of pyometra in cases of pseudohermaphroditism, this is part of a process of sexual differentiation that is It begins in the uterus and continues in development until reaching maturity, dividing into three phases: chromosomal, gonadal and phe-notypic sex, an alteration in sexual development is the syndrome of persistent Mullerian ducts that is present in cases of apparent hermaphroditism male, which is hereditary, autosomal, recessive in XY individuals, in which the presence of the uterus and other structures of the female reproductive tract is observed in a male animal, derived from an interference in the response to the anti-Müllerin hormone at the receptor, which has been reported in dogs of the Miniature Schnauzer breed, from this perspective in this article we report So three clini-cal cases observed in a veterinarian in Bucaramanga, the symptoms reported indicate episodes of decay, fever, diarrhea, abdominal palpation pain and tenesmus, alterations in blood chemistry, in the clinical examination pyometra was observed, and purulent dripping discharge from of the urethra, gynecomastia and cryptorchism, recurrent appearance in cases of canine pseudohermaphroditism.
