Cystic endometrial hyperplasia (CEH)-pyometra syndrome is the most common uterine pathological condition reported in breeding bitches, however, their described effects on fertility are limited to uterine disorders and conception rates. As the preantral follicle population represents the available reserve of gametes recruited during the lifespan, the aim of this study was to evaluate the effects of CEH-pyometra syndrome on the:(i) preantral follicle morphology, (ii) developing follicle rates, and (iii) preantral follicle and stromal cell densities.

The agricultural professionals are ethically obligated to provide good care for the animals under their care. We analysed Brazilian agricultural science students? profiles based on their perceptions of animal welfare (AW). The survey included 239 students from agronomy, animal science, and veterinary courses in 44 universities. A factor analysis and a cluster analysis identified four students? profiles. ?The farm animal stewards?

ABSTRACT.- BACKGROUND:The global beef market demands the meat industry to ensure product quality and safety in markets that are often very distant. The present study aimed to evaluate the effects of chilled (CH, 120 d) and chilled-then-frozen (CHF, 28 d + 92 d) storage conditions of beef vacuum packaged (VP) and vacuum packaged with antimicrobial (VPAM) on meat quality, oxidative status and microbial loads. Treatments resulted from the combination of storage condition and packaging type:VP + CH, VP + CHF, VPAM + CH and VPAM + CHF.

This work aimed to evaluate the effect of including 2 functional feed ingredients in a diet with a high proportion of pasture silage on in vitro ruminal fermentation, nutrient disappearances, and ruminal microbiomes.

RESUMEN:El objetivo de este estudio fue optimizar un análisis mediante PCR en tiempo real con curvas de disociación para la detección confiable y económica del inserto mutante de 7,5 Kb del elemento transponible bovino BoERVK en el exón 5 del gen de la Apolipoproteína B (APOB), determinante de la deficiencia de colesterol - CD - (OMIA 001965-9913).

The New World screwworm, Cochliomyia hominivorax, is an obligate parasite, which is a major pest of livestock. While the sterile insect technique was used very successfully to eradicate C. hominivorax from North and Central America, more cost-effective genetic methods will likely be needed in South America. The recent development of CRISPR/Cas9-based genetic approaches, such as homing gene drive, could provide a very efficient means for the suppression of C. hominivorax populations. One component of a drive system is the guide RNA(s) driven by a U6 gene promoter.

El sobrepastoreo de los campos naturales ha determinado la disminución de especies nativas de alto valor forrajero, como es el caso de Bromus auleticus Trin. ex Nees en el bioma Campos. La reintroducción de especies nativas de alto valor forrajero sembradas sobre el campo natural aparece como una tecnología promisoria para la recuperación de dichos ambientes. No obstante, no ha sido suficientemente desarrollada principalmente por la falta de semilla comercial de la especie y por falta de información que oriente el manejo de la implantación.

ABSTRACT.- Ensifer (syn. Sinorhizobium) meliloti U143 is an effective nitrogen-fixing strain isolated from Uruguayan soils. For decades, this strain has been used as an inoculant for different alfalfa cultivars. Here we report for the first time a characterization of the U143 elite strain that includes the preliminary genomic sequence, its annotation, and physiological parameters related to its symbiotic efficiency and nitrate respiration capacity. Through Illumina sequencing, the genome of the U143 strain was sequenced.
