Digestion in the Pig
نویسنده
چکیده
A knowledge of the sites of digestion and extent of digestion of nutrients is essential for the formulation of diets to meet the requirements of pigs. This is of particular importance for young pigs, where there is rapid gastrointestinal development, but it must be taken into consideration in formulating diets from birth, through pregnancy and lactation. The following four papers discuss the development of the digestive system and digestibility, with particular emphasis on proteins.

Introduction & Objective: 130 heteroxenous species of sarcosytis with different life cycle and pathogenesis have been recognized. The pathogenic species for humans are S. hominis from cattle and S. suihominis from pig that humans are definitive and cattle and pig are intermedi-ate hosts. Some species of Sarcocystis can cause important economic loss and disease in livestock, and health issues ...

Introduction: Spermatogonial Stem Cells (SSC) are the originators and beginning points of the spermatogenesis process. Moreover, they are considered the only stem cells in the body that could transfer genetic information to the next generation through gametogenesis. This study aimed to investigate the potency and power of SSC under in vitro and in vivo conditions. Materials & Methods: Enzym...

This paper investigates anaerobic co-digestion of pig manure and algae (Scenedesmus sp.) with and without extraction of intracellular algal co-products, with views towards the development of a biorefinery concept for lipid, protein and/or biogas production. Protein and/or lipids were extracted from Scenedesmus sp. using free nitrous acid pre-treatments and solvent-based Soxhlet extraction, resp...

Digestion of crop silage (Zea mays L. and Miscanthus sacchariflorus) with 0%, 7.5%, 12.5% and 25% pig manure as co-substrate was performed in continuous stirred-tank reactors, for a constant hydraulic retention time of 45 d and organic load rate of 2.1 g L(-1)d(-1). A matrix of correlations between biogas/methane production and parameters of anaerobic digestion was created in order to estimate ...
متن کاملRemoval of residual organic matter, phosphates and ammonium from thermofilically digested pig manure
Full-scale anaerobic digestion of pig manure often resulted in liquid effluents with considerably high organic matter, ammonia and phosphates content. If not enough agricultural land is available, the disposal of this effluent requires additional treatment. Different process scheme for reduction of the organic matter and nutrients from thermofilically digested pig manure were tested in full-sca...
متن کاملThe influence of porcine pancreas digestion parameters and islet histomorphology on islet isolation outcome.
Transplantation of the pig islets of Langerhans is considered as the future treatment for patients suffering from type I diabetes mellitus. Despite the adaptation of modified Ricordi method and highly purified collagenase, the results of pancreas digestions are precarious. Selection of proper donor and optimal digestion procedure are fundamental. The aim of this study was to assess the impact o...
