Manganese requirements of broiler breeder hens
Poultry Science, 2020 The present research was conducted to assess Mn requirements of broiler breeder hens. One hundred and twenty Cobb 500 hens, 22 wk of age, were individually allocated in cages. After fed a Mn-deficient diet (22.2 ppm), hens were randomly placed in treatments having 6 increments of 30-ppm Mn. All trace minerals were from laboratory grade sources being Mn

Safety of improved Milbond-TX mycotoxin binder when fed to broiler breeders above recommended levels [PDF]
, 2014 An increasing concern in poultry nutrition is the effects of mycotoxins in contaminated grain. Several new products have come onto the market that chemically bind these toxins preventing mycotoxicosis. However, many of these products have not been tested

Zinc requirements of broiler breeder hens
Poultry Science, 2019 One hundred and twenty Cobb 500 hens, 20 wk of age, were randomly allocated into individual cages with the objective of estimating their Zn requirements. The study was composed of 3 phases: adaptation to cages (basal diet), depletion (deficient diet containing 18.7 ± 0.47 ppm Zn) for 7 wk, and experimental phases.

Housing and management of broiler breeders and turkey breeders.
, 2012 AbstractThis chapter describes the housing and management of broiler breeders and turkey breeders in Europe. The majority of broiler breeders in Europe are the standard, fast growing genotype, but 18-20% of the broiler breeders are dwarf parental females that produce standard and alternative (medium or slow growing) broilers.

Animal Research and One Health, EarlyView.Activo Liquid and Halquinol inhibit Salmonella and Escherichia coli in culture media. Activo Liquid exhibits bactericidal action, whereas HA is bacteriostatic, and their combination results in positive or indifferent interactions. This combination effectively inhibits E. coli throughout digestion simulation, thus reducing the required concentrations of

Restricting Growth of Broiler Breeder Pullets
Poultry Science, 1969 Abstract Restricting rate of gain and delaying sexual maturity of pullets are important considerations in producing a profitable broiler breeder flock. Most of the existing programs for rearing broiler pullets are based on some type of feed restriction, or the use of diets designed to limit nutrient intake starting around 8 to 10 weeks of age ...
