Use of straw and wood shavings as nest material in primiparous does.
ABSTRACT. In rabbit production, several materials such as hay, straw, wood shavings or waste wool and cotton are used as nesting materials during parturition. In this work, straw and wood shavings were studied as potential materials for nest boxes, and a choice test was designed for this purpose. Two replicates of 30 primiparous does each were carried out. Does were housed 10 d before parturition in a double commercial cage, so each doe had access to 2 different nest boxes.
Effect of a povidone-iodine intrauterine infusion on progesterone levels and endometrial steroid receptor expression in mares.
BACKGROUND. Intrauterine infusions have been widely used for the treatment of endometritis in the mare. Nevertheless, their consequences on endocrine and endometrial molecular aspects are unknown. We studied the effect of a 1% povidone-iodine solution intrauterine infusion on progesterone levels, endometrial histology and estrogen (ERα) and progesterone (PR) receptor distribution by immunohistochemistry.Methods:Fourteen healthy mares were used in this study.
Quantitative trait loci analysis for resistance to cephalosporium stripe, a vascular wilt disease of wheat.
ABSTRACT. Cephalosporium stripe, caused by Cephalosporium gramineum, can cause severe loss of wheat (Triticum aestivum L.) yield and grain quality and can be an important factor limiting adoption of conservation tillage practices. Selecting for resistance to Cephalosporium stripe is problematic; however, as optimum conditions for disease do not occur annually under natural conditions, inoculum levels can be spatially heterogeneous, and little is known about the inheritance of resistance.
Enfermedad de las hojas de los Eucalyptus provocada por Mycosphaerella spp.: Situación en Uruguay y alternativas de manejo.
La enfermedad del follaje de los Eucalyptus provocado por Mycosphaerella spp. es actualmente el principal problema sanitario de Eucalyptus globulus en Uruguay. La enfermedad genera importantes daños en plantaciones jóvenes (de menos de dos años, previo al cambio de follaje). Los síntomas iniciales son manchas necróticas, principalmente en follaje juvenil y en hojas nuevas. Posteriormente, en casos severos, se produce la caída de las hojas afectadas (defoliación), y eventualmente la muerte de ápices.
