The objective of this study was to investigate the application of BLUP and ssGBLUP in different scenarios of uncertain paternity using data from a Nellore cattle population. The analyzed data set was provided by the National Association of Farmers and Researchers (ANCP). The data set contained information from 18 Nellore herds located in the southeast and mid-west regions of Brazil, which participate in the ANCP breeding program. © American Society of Animal Science 2017

Grassland biomes provide valuable ecosystem services, including nutrient cycling. Organic phosphorus (Po) represents more than half of the total P in soils. Soil microorganisms release organic P through enzymatic processes, with alkaline phosphatases, acid phosphatases and phytases being the key P enzymes involved in the cycling of organic P.

ABSTRACT.- AbstractThe results of the first evaluation of the Prolific Sheep Project of INIA (2008-2011) demonstrated that the crossbred biotypes Corriedale by East Friesian or Corriedale by Finnish Landrace weaned 60 % more lambs than pure Corriedale and, on the other hand, the crossbred East Friesian by Finnish Landrace weaned 85 % more than pure Corriedale. However, and under the same productive conditions, the behavior at lambing and colostrum production of these new biotypes are unknown.

ABSTRACT.- The levels of resistance to bacterial wilt (BW) of potatoes caused by Ralstonia solanacearum (Rs) are limited. Solanum commersonii (cmm) is a wild tuber-bearing potato highlighted for its resistance to BW.

ABSTRACT.- Sustainability of most vegetable family farms in Southern Uruguay is threatened by low income and the deterioration of natural resources. This study quantified the effect of the inclusion of different alternatives of livestock production in the structure, and economic and environmental performance of different types of vegetable farms. Based on two farms as case studies, we conducted a model based exploratory study at farm scale. The results suggested that the inclusion of livestock production in vegetable family farms is a key factor in reducing erosion of the cultivated area.
