Farm practices survey and modelling to estimate monthly NH3 emissions from swine production in 12 Ecoregions of Canada[swine abstracts]This paper describes a new model to estimate NH3 emissions from the swine sector, relying heavily on a recent survey of swine producers to determine the present N and manure management practices. |
The effect of type of rooting material and space allowance on exploration and abnormal behaviour in growing pigs[swine abstracts]The experiment aimed to investigate the effect of type of rooting material and space allowance on explorative and abnormal behaviour in growing pigs. Thirty-six pens with partly slatted concrete floor were allocated to one of four treatments: (1) low space allowance and maize silage as rooting material, (2) high space allowance and maize silage as rooting material, (3) low space allowance and straw as rooting material, and (4) high space allowance and straw as rooting material. |
Organization of replacement IV[Management]Carles Casanovas Another convenient option for controlling replacement entry is to incorporate the information on the planning board of production. |
Direct and indirect transmission of four Salmonella enterica serotypes in pigs[swine abstracts]Feed-borne spread of Salmonella spp. to pigs has been documented several times in recent years in Sweden. Experiences from the field suggest that feed-associated serotypes might be less transmittable and subsequently easier to eradicate from pig herds than other serotypes more commonly associated to pigs. |
Cleaning comes before disinfection[What the experts say ]Jake Waddilove It is much more difficult to achieve a good quality of cleaning if the surface you are trying to clean is particularly pervious to water (for example wood) and has many cracks and hidden areas. |
Post-insemination level of feeding does not influence embryonic survival and growth in highly prolific gilts[swine abstracts]This study was designed to investigate the influence of a high level of feeding during early gestation on embryonic survival and variability of embryonic development in hyperprolific LW gilts. |
Dietary protein intake and stage of lactation differentially modulate amino acid transporter mRNA abundance in porcine mammary tissue[Nutrimail]Mammary gene expression of AA transporter is not affected by dietary protein intake. |
