Los parvovirus pertenecen a un grupo de virus no envueltos, capaces infectar en una amplia variedad hospedadores domésticos y silvestres, pudiendo causar diversos cuadros clínicos como fallas reproductivas cerdos bovinos, enteritis caninos aves corral, panleucopenia felinos, hepatitis equinos, enfermedad respiratoria cutánea humanos. Estos son mayormente especie-específicos, aunque hay evidencia transmisión interespecie, especialmente animales silvestres. Su genoma está compuesto por cadena...
This study investigated follicular development during and after postweaning altrenogest treatment of primiparous sows in relation to subsequent reproductive performance. Primiparous (n = 259) were randomly assigned at weaning (d 0) 1 4 groups: control (no altrenogest, n 71), RU4 (20 mg from d -1 2, 62), RU8 6, 65), or RU15 13, 61). Average size (measured by ultrasound) increased resulted larger follicles the start phase for RU4, RU8, compared with controls (5.3 ± 0.9, 5.5 1.3, 5.1 1.2, 3.4...
Little is known about the ecology of critically important antibiotic resistance among bacteria with potential to be opportunistic human pathogens (e.g., Escherichia coli ) on South American farms. By studying 70 pig and dairy cattle farms in central-eastern Argentina, we identified that third-generation cephalosporin (3GC-R) E. was mediated by mechanisms seen more often certain species 3GC-R were likely co-resistant florfenicol amoxicillin/clavulanate. This suggests on-farm usage key...
This is a risk assessment for six mineral contaminants and four essential minerals. A total of 1,466 samples were collected from 18 product categories during 2010 to 2018. The divided into 11 finished feed (689 samples) seven ingredient (777 samples). Mineral vitamin/minerals mixes (565 the predominant products in categories, beef cattle (351 was categories. Samples analyzed up 10 minerals: arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), molybdenum (Mo), mercury (Hg),...
<p>Objectives of this study were to determine the fatty acid composition and analyze sensitivity lipid peroxidation different boar fresh semen samples from two herds, H1 H2. Lipid was evaluated using chemiluminescence (cpm/mg protein) profile by means gas chromatography. The saturated content found in analyzed spermatozoa approximately 43% 33% H2, whereas total unsaturated 47% 59% When control ascorbate-Fe++ dependent compared, it observed a significant increase light emission....
Abstract Control measures are being introduced globally to reduce the prevalence of antibiotic resistant (ABR) bacteria on farms. However, little is known about current and molecular ecology ABR in key opportunistic human pathogens such as Escherichia coli South American Working with 30 dairy cattle farms 40 pig across two provinces central-eastern Argentina, we report a comprehensive genomic analysis third-generation cephalosporin resistance (3GC-R) E. . 3GC-R isolates were recovered from...
La evaluación de los registros reproductivos y las causas descarte en reproductoras porcinas es una herramienta imprescindible para aplicar estrategias eficaces lograr mayor eficiencia productiva. Esto se debe al impacto económico productivo que representan la compra preparación nuevas reproductoras. Las limitaciones presenta el examen clínico reproductivo hembra porcina hace necesaria aplicación herramientas permitan dar un enfoque más objetivo a políticas decisiones reproductivo. Entre...
La inseminación artificial en la especie porcina es una herramienta de gran utilidad que permite grandes avances industria porcícola, tanto nuestro país como el mundo. biotecnológica reproducción se aplica producción animal con fin aumentar eficiencia productiva, lograr un mayor progreso genético e incrementar desempeño reproductivo. Existen diferentes métodos porcinos, permiten variar volumen y número espermatozoides dosis inseminante al modificar lugar deposición del semen. El objetivo...
Many first litter sows suffer from a suboptimal reproductive performance in the second cycle, shown by an increased weaning-to-oestrus interval, low farrowing rate and small size (e.g.Thaker & Bilkei 2005).This so-called 'second syndrome' may be related to suppressive effects of negative energy balance on lactational follicle development, since several authors have that pre-follicular phase feeding levels (either during lactation or luteal oestrus cycle) affect antral pool subsequent...
