| Corneal endothelium constitutes a monolayer of polygonal cells. The integrity and health of this layer are essential for the maintenance of normal corneal transparency. This study reported by the first time in a detailed way the ultrastructural morphology and morphometry of the corneal endothelium in normal adult crossbred pigs by using scanning electron microscopy (SEM). A regular pattern of polygonal cells, with predominantly hexagonal cells and clear cell borders, was observed. An oval nucleus that bulges in the centre of the cell, cilia (2-4) in a few peripheral cells, openings of the pinocytotic vesicles, microvilli, borders bars and interdigitated cell borders were observed. The mean endothelial cell area was significantly higher (P<0.05) in the... |

| ABSTRACT: Optimizing nutrient efficiency is essential in order to increase sustainability of pig production systems, especially where the growing demand for food must be met at an affordable cost, without compromising environmental resources. To make this happen, it is necessary to develop efficient methods to accurately estimate the nutritional requirements of animals, as well as develop equipment and systems that allow for applying such expertise in the production system. Estimating the nutritional requirement of pigs through mathematical models, considering several factors that can impact the requirement, is a key factor to reduce the environmental load from pig production. Likewise, feed formulation and feeding programs, can help to achieve this. In... |

| ABSTRACT: Pigs transportation is a critical stage for their welfare and can directly influence the rates of carcass condemnation. The objective of this research was to study the injuries and condemnation data recorded in the Federal Inspection System (SIF) as potential welfare indicators during pig transport. In federally inspected slaughterhouses in the State of Paraná, Brazil, from january 2011 to December 2016, 1.4% (602,006) of carcasses were condemned, 15.0% (90,426) as a result of injuries related to transportation. From total condemnation cases, 12.1% (72,759) were due to traumatic injury, 2.5% (15,144) to PSE, 0.4% (2,327) to dead on arrival and 0.03% (196) to other transportation welfare indicators. There was no correlation between the... |
