Abstract:
In an experiment with 288
laying hens from a commercial strain (Hy-line W36), the effect of partial
and total replacement of soybean meal, corn grain, wheat grain and wheat
bran with dried tomato pulp (DTP) on performance and egg quality was
determined. In the 12 week experiment, hens (27 to 38 weeks of age)
were allocated to four dietary treatments being: DTP0, DTP50, DTP100
and DTP150 of 72 birds each, and received a diet ad libitum.
The diet for DTP0 treatment had no DTP (control), while those for treatments
DTP50, DTP100 and DTP150 included 50, 100 and 150 kg/t of DTP, respectively.
Inclusion of DTP at levels up to 100 kg/t in diets of laying hens increased
egg production and egg mass by 2.7% and 4.1%, respectively, compared
to the control and resulted in similar traits, relative to final BW,
egg weight, daily feed consumption, egg shell weight, egg shell thickness,
haugh units and yolk color. However, inclusion of DTP at higher level
(150 kg/t of diet) decreased egg production and egg mass by 3.6% and
3.0%, respectively, and increased feed efficiency by 2.9% compared to
the control. Thus, DTP can be used as an alternative feedstuff in laying
hen diets, at inclusion levels up to 100 kg/t without negative effects
on performance and egg quality.
