Two hundred and eight commercial egg type hi-line hens were used in a complete randomized design with 12 treatments in a 3*4 factorial arrangement for a 9 weeks period to study the effects of corn replacement by triticale in layers diet.
Based on metabolizable energy estimation of triticale, a series of is caloric and is nitrogenous layers diets were formulated in which four different levels (0,25,50,and 100%) of the corn were replaced by either untreated, water treated or characteristic performances of hens fed the twelve experimental diets were compared with those fed control corn-soybean meal diet.
Feed consumption, egg production, egg weight, feed conversion rate, egg specific gravity, egg shell weight and albumen quality were measured weekly and for the whole 9 weeks period of experiment. The data were analyzed among the hens fed experimental diets and compared with those feed control corn-soybean meal diet.
The results indicated that replacement of corn by triticale,either untreated or treated has no effect on feed consumption. Feeding up to 50 percent of untreated and 75 percent enzyme treated triticale instead of corn had no effact o egg weight and beyond that reduced the egg weight. Egg production was not afacted by feeding up fo 50 percent replacement and the treating methods had no effect on egg weight. Feed conversion rate statistically the same in hens fed up to 75 percent triticale instead of corn and beyond that was increased. Egg specific gravitand egg shell weight were not affected by levels of triticale and the methods of treatment. Albumen quality was not affected by feeding up to 50 percent triticale instead of corn and methods of treatment had no effect on albumen quality.
