ABSTRACT.- Feathering in apple nursery trees is a critical operation used to increase the quality of planting material. Plant growth regulators (PGR) could be used to form feathers in apple nursery trees. The main goal was to study the impact of different PGR and concentrations on feathering promotion in different nursery apple trees.

ABSTRACT.- Plants deploy diverse anti-herbivore defences which reduce feeding and performance of herbivores. Temperate grasses use silicon (Si) accumulation and Epichloë-endophytes for physical and chemical (i.e. endophytic-alkaloids) defence against insect herbivores. Recent studies suggest that Epichloë-endophytes increase Si accumulation in their host grass. It is unknown, however, how this affects Si-deposition on the leaf surface, their impacts on insect herbivore feeding efficiency and their immunity to potential infection/parasitism.

Soybean stem canker (SSC) is an important disease caused by different Diaporthe spp., including D. aspalathi, D. caulivora and D. longicolla, that leads to soybean (Glycine max) yield losses around the world. Most studies have been focused on the morphological characterization and molecular identification of Diaporthe spp. present in SSC lesions. Several soybean resistance loci to Diaporthe spp. causing SSC have been identified, although the molecular identities of the resistance genes are at present unknown.

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).
