To evaluate terminal-sire breeds, harvest BW, prefabrication carcass measurements, and organ weights were evaluated over 3 yr for 518 crossbred wether lambs (ovis aries). Lambs were produced by single-sire matings of 22 Columbia, 22 USMARC-Composite (Composite), 21 Suffolk, and 17 Texel rams to adult Rambouillet ewes. Lambs were raised to weaning under an extensive western rangeland production ...

When choosing a suitable technique for regression and classification with multivariate predictor variables, one is often faced with a tradeoff between interpretability and high predictive accuracy. To give a classical example, classification and regression trees are easy to understand and interpret. Tree ensembles like Random Forests provide usually more accurate predictions. Yet tree ensembles...

Forest regeneration following timber harvest is a principal source of habitat for early-successional birds and characterized by influxes of early-successional vegetation and residual downed woody material. Early-successional birds may use harvest residues for communication, cover, foraging, and nesting. Yet, increased market viability of woody biomass as bioenergy feedstock may intensify harves...

Apple (Malus × domestica Borkh.), a popular and widely cultivated fruit world-wide, contains bioactive triterpenes and phenolic compounds with potentially valuable pharmacological functions. This thesis investigated the effects of pre-harvest and postharvest factors on concentrations of these bioactive compounds in apples. It also studied the effect of ozone treatment, before or during storage,...

OBJECT Improved precision fertilization by introducing sensors and remote control to secure fruit yield and reduce nutrient leaching in soil culture. MATERIAL AND METHODS We broadcasted before bedding and mulching 50 g m-2 of a multi-mineral fertilizer. Beds had two plant rows 20 cm apart, with plant distance of 25 cm. Experimental design was split plot with three replications and three treat...

Pineapple can be affected by fruit collapse, a disease caused the bacterium Dickeya zeae. However, adequate fertilization increase fruit’s resistance to this illness. Therefore, impact of preharvest foliar calcium and silicon on pineapple quality collapse incidence was assessed in study. The experiment implemented split-plot design with two factors. first factor has terms inoculation (flower in...

OBJECTIVE To assess health-related quality of life in sugarcane cutters. METHODS Longitudinal study conducted in a sugar and ethanol plant located in the western region of the State of São Paulo (Southeastern Brazil) from April (pre-harvest) to October (harvest) 2010. A total of 44 sugarcane cutters, smokers and non-smokers, was evaluated in three periods: pre-harvest, at the end of the third...

We investigated the effects of coloring agent and potassium sulfate (K2SO4) foliar sprays, reflective aluminium porous film covering on orchard floor enhancement red peel coloration in ‘Hongro’ apples. Foliar spray sulfate, mulching before harvest increased Hunter a value anthocyanin content fruit peels at harvest. In addition, micro-porous had best effect promoting fruits lower inner canopy, n...

With an increasing number of outbreaks and illnesses associated with produce contaminated before harvest, understanding the potential and mechanisms of produce contamination by enteric pathogens can aid in the development of preventative and post-harvest processing measures to reduce microbial populations. Enteric pathogens localized at subsurface sites on leafy green plant tissue prevent their...
