Selsaf® to improve egg production
A 2011 trial in the Czech Republic, featured 1050 breeder/layer hens (Hubbard JA57) and 112 male breeders (M77), supplemented either with Selsaf® or sodium selenite (control). Both groups, from 23-62 weeks of age, were given 0.3 ppm of selenium in their feed. Parameters were measured in periods of 4 weeks.
Selsaf® supplementation resulted in numerically higher egg production per hen, with about 7 eggs more per hen than in the inorganic selenium group. Selsaf® also improved fertilisation rates and increased the number of hatched chicks per hen. An extra 12 chicks hatched per hen was recorded in the Selsaf® group, compared with the inorganic selenium group.
