INTRODUCTION• Zn, Cu and Mn are nutrients required in small amounts, sensitive to

excess or competition between metals. • A 15 weeks (wk 21-36) study was conducted by Zootests in

2 commercial broiler breeder facilities with Hubbard genetic.• The objective was to determine the impact of feeding reduced levels of

MINTREX® (CMA, chelates of methionine analogue) vs. industry levels of ITMs (inorganic trace minerals) in breeder hens on egg quality, hatching rate and progeny quality.

RESULTS• A numerical improvement of egg output, feed conversion and lower

mortality was observed with the CMA treatment in the two houses

CONCLUSIONPresent data indicated that feeding broiler breeder hens reduced levels of chelates of methionine analogue compared to commercial levels of inorganic trace minerals tended to improve lay performances and significantly improved hatching rate and progeny mineralization, without detrimental effects on other parameters monitored.

• No differences were observed for egg weight (P=0.99) and shell breaking strength (P=0.14)

• Hatching rate was significantly (P=0.048) improved by 1.92% for group fed CMA compared to group fed ITMs.

• Ash content of chicks produced from hens fed CMA significantly increased by 4.3% (P=0.02) while tibia Zn content tended to increase by 3% (P=0.19).

MATERIALS AND METHODS• A total of 15200 male line of Hubbard breeder hens were distributed

into 4 houses (with floors having 1/3 slats and 2/3 litter) with 3800 hens/house.

• Study had 2 treatments (T1 and T2) each with 2 replicate houses per treatment and consisted of 100, 10 and 100ppm of Zn, Cu and Mn, respectively, as oxide, sulfate, and oxide (T1) and 56, 14 and 56ppm of Zn, Cu and Mn, respectively, as chelates of methionine analogue (CMA) (T2).

Treatments:

• Supply in premix and trace element was reduced to 92% from 21 to 24 wk.

• At week 36, 210 eggs per house were evaluated for average egg weight and egg shells breaking strength, and 4150 eggs per house were monitored to evaluate hatching rate.

• At birth, 200 left tibias (50 chicks per treatment per house) were sampled and pooled for tibia ash, and tibia Zn analysis on DM basis to assess progeny quality.

• A correction of methionine so that the 3 treatments be isomethionine.
