February - Biosecurity for Breeder Farms
Biosecurity can be defined as a comprehensive range of clear procedures aiming to minimize the possibility of introduction of undesirable pathogens into a poultry operation. The extent of such biosecurity rules depends mainly on the prevalence of diseases in the area, the value of the birds, short and long-term company goals, customers’ expectations, level of commitment and availability of resources.
April - Efficacy of Several Salmonella Vaccination Programs Against Experimental Challange with Salmonella Gallinarum in Commercial Brown Layer and Broiler Breeder Hens
Salmonella enterica serovar Gallinarum (SG) is the etiologic agent of Fowl Typhoid, a severe systemic disease of chickens and other galliform birds (Shivaprasad, 2000). Salmonella Gallinarum is a non-motile host specific bacterium in domestic poultry. Infection in chickens occurs at all ages and is characterized by severe hepatomegaly and splenomegaly accompanied by liver with bronzing aspect, anemia, and septicaemia (Shivaprasad, 2000). The disease is dose-dependent and differences in pathogenicity may be found depending upon the susceptibility of the infected genetic line of chickens (Oliveira et al., 2005).
June - Questions to Ask When Your Eggs do Not Hatch
Are chick numbers down? Are there more culls and seconds? Was the hatch early, on time or late? Are there dead chicks stuck to the hatch baskets?
Do an egg breakout of debris remaining on five hatcher baskets and decide if the problem is embryo mortality or infertility. If it is embryo mortality then decide when they died: early (first week), mid-term or late on the development. Were there many pips suggesting as late hatch for example?
In other words, define the problem!
August - Salmonella Gallinarum 9R Strain as Vaccine
The rough (R) strain of Salmonella Gallinarum (SG), named as 9R, was developed in England from a number 9 field virulent smooth strain, with a paper published by Smith in 1956, based on the knowledge that rough mutants lose their virulence capability. Many publications have proved its safety as a vaccine, non reverse in virulence, and ability to protect chickens against fowl typhoid (FT). Since then, it has been used extensively in many countries where the FT is endemic, mainly in brown layers, but also in white egg layers and breeders. One of the greatest advantages of the use of the SG 9R vaccine is that it gives good protection and does not interfere with the tests used for pullorum-typhoid control. Besides controlling FT, the SG 9R vaccine has been used in several countries as an additional tool in the control of Salmonella Enteritidis (SE) in commercial layer flocks. Better immunity, lower cost in comparison with kill products, no local reactivity, are its strongest points.
