Como se ha manifestado: El origen de la Zootecnia en Colombia se remonta a 1954, año en que se consideró necesaria la intensificación de los estudios agropecuarios en el país, específicamente para la formación de profesionales en el área de producción animal (http://www.elempleo.com/co/noticias/noticias-laborales/zootecnia-diversos-campos-de-desempeno-3352). Desde su inicio, este programa ha venido contribuyendo al desarrollo del campo colombiano mediante la docencia, investigación y extensión y proyección social en el campo de las ciencias para la producción animal. A pesar que la Zootecnia es considerada una carrera importante en materia de seguridad e inocuidad alimentaria a nivel mundial, el profesional de la Zootecnia deberá actuar en toda la cadena de producción animal, requiriendo de procesos endógenos de reflexión, trabajo en equipo y reingeniería de las entidades que forman a dichos profesionales, de manera que sus aportes tengan un alto impacto en el desarrollo económico, social y medioambiental del campo (http://www.anzoo.org/magazine/images/revista/RCZ_2b.pdf)

Iguana iguana eggs were physically and chemically characterized. the physical tests were performed by methods of spectrophotolorimetry, calibrator, tape measure, micrometer, flexometer and flotation and chemical tests according to the guidelines required by A.O.A.C. The results obtained showed with respect to the physical characteristics: On average, a weight of 14.78 (g); longitudinal diameter 39.70 mm (±0.49), cross-sectional diameter 26.41mm (±0.6), perimeter length 11.55 cm (±0.2), perimeter width 9.07 cm (±02), among other characteristics evaluated. Regarding the chemical composition, in shell 51.23% (±3.02) Inorganic Calcium; 20.17% (±1.56) Inorganic Phosphorus; in albumen 51.47% (±1.05) of crude protein, 17.02% (±1.33) of raw fat and in compact albumen a weight of 3.83 g (±0.21). Through multiple regressions, it was determined that the weight depends on the percentage of shell and the compact albumen in 87%. The specific gravity depends not only on the perimeter length but also on the percentage of shell and the thickness of this in the equatorial zone in a 86.3%. The percentage of shell, weight, specific gravity and thickness in the equatorial zone in 88.3%. The chromatic characterization determined its color between medium yellow and yellowish white.

The aim of this study was to analyze the degree of fluctuating asymmetry in wing traits and digits of three common bat species (Artibeus lituratus, Artibeus planirostis and Carollia perspicillata) in extensive livestock systems from Córdoba department, Colombia. To do this, specimens from the Mammalian Collection at the Museo Javeriano de Historia Natural of Pontificia Universidad Javeriana (Bogotá, Colombia) were analyzed. All specimens belonged to fragments of tropical dry-forest immersed in extensive livestock systems of Córdoba department. To parse out fluctuating asymmetry, 11 wing traits were used. To assess the existence of asymmetry, nonparametric U test was applied. Finally, to evaluate the existence of significant differences among digits, nonparametric one-way analysis of variance were carried out. In total, 114 specimens were analyzed (A. planirostris=40, A. lituratus=33, C. perspicillata=41). The results showed no statistical differences (p> 0.05) in most of wing traits. Little variation in wing traits was due to its relevance on flight performance and the high tolerance to perturbation of these bat species. “Differential-mortality” hypothesis and “Big Mother” hypothesis are discussed. Results from this work suggest that livestock systems do not severely affect these species. Further studies should consider the type of management to know which one provides better conditions for bats.

Ultrasound in small animals has advanced enormously in recent years, often replacing conventional radiographic studies. Abdominal ultrasound is a diagnostic aid of great importance for veterinary clinics. At present, its implementation has increased because it is a non-invasive technique, fast and timely, which together with the clinical evaluation of the patient allows us to identify pathologies in a short period. The objective of this report is to identify the frequency of abdominal pathologies diagnosed by means of ultrasound, as well as the most affected organ. For this, information was collected from the database of ultrasound reports of the southern veterinary clinic, located in Sabaneta Antioquia, between December 2016 and April 2017, in which 119 abdominal ultrasounds were performed, of which 82% was developed in canines and 18% in felines. The gastroenteric tract being the most frequently affected (23.33%), followed by the liver (16%) and the spleen (8%). The most frequently reported pathology was gastric inflammation (8%), followed by hepatitis (7.33%) and gastroenteritis (4%).

The objective of this research was to determine protein serum concentrations in cows and heifers of the womb under grazing conditions in the low tropic of Colombia. Blood samples were taken from 6 cows and 6 clinically healthy heifers, in which descriptive statistics of total proteins, albumin, globulins, urea and NUS were determined. The results obtained in cows were: total proteins 6.53±0.73 (g/ dL), albumin 4.10±0.62 (g/dL), globulins 2.43±0.94 (g / dL), urea 18.14 ± 4.21 (mg/ dL) and NUS 8.45±1.96 (mg/dL); and for heifers the following: total proteins 6.07±0.93 (g/dL), albumin 4.40±0.89 (g/dL), globulins 1.67±1.33 (g/dL), urea 20.40±6.10 (mg/dL) and NUS 9.51±2.84 (mg/dL). There were no significant differences between the categories studied, so it is concluded that both cows and heifers are in similar metabolic phases determined in terms of their nutritional requirements, therefore the concentrations of analytes in the body are very similar.

A case of bovine tuberculosis was reported in a Holstein female of approximately 350 kg in weight, which was attended by the animal pathology service of the Faculty of Veterinary Medicine and Zootechnics of the University of Viçosa, Brasil. The owner reported progressive wasting, due to the poor state of health it was decided to sacrifice the animal and later moved to the area of ​​pathology where the necropsy was performed. Hairy, pale mucous membranes and marked cachexia were evidenced in the external inspection of the corpse, the anatomopathological findings at necropsy revealed important injuries such as: nodular case areas in muscles in the intercostal region, pleura, lung, liver and pre-scapular lymph nodes. The definitive diagnosis of the corpse was bovine tuberculosis.
