“…A lower mortality rate in laying hens supplemented with AA was indicated by Perek and Kendler (1963) and Herrick and Nockels (1969), but these results were not significant. There is also some evidence which shows that AA supplemented diet is beneficial in reducing body temperature (Thornton, 1962;Lyle and Moreng, 1968).…”

Two trials were conducted to investigate the effects of dietary ascorbic acid (AA) on the performance of laying hens maintained under high environmental temperatures (32.2 °C and 33.3 °C, respectively), and a third trial was carried out under ambient conditions (12.8 °C to 17.3 °C).Weekly changes in egg yield, shell deformation, percentage of cracked eggs and body weight showed an improvement in the AA-supplemented birds but the differences were non-significant. Egg yield and percentage of cracked eggs were not affected when the diet was supplemented with AA under ambient conditions.

“…However, this result was not repeated consistently (Thornton and Moreng, 1959;Thornton, i960). Herrick and Nockels (1969), while working under ambient temperatures also observed a significant improvement in interior egg quality of birds treated with a high dose of AA (2600 mg/kg).…”

“…Since dietary ascorbic acid results in higher plasma ascorbic acid concentrations, this work is in agreement with previous reports (Dorr and Nockels, 1971;Herrick and Nockels, 1969). The significant linear logdose response to graded levels of ascorbic acid is similar to that noted by Giroud e^ (1938) for man and guinea pigs.…”

“…Ascorbic acid supplementation of the diet of laying hens reduced the incidence of stress [1, 5, 10, 13], it increased the production and improved egg quality [2, 3,6,7,8,11,12]. Though, KECHICK, SYKES [4] did not find any relationship between ascorbic acid supplementation of rations and productive and qualitative parameters of the produced eggs.…”

SUMMARYThe egg quality may be influenced by some nutrients added to laying hens diets and among these nutrients, the ascorbic acid is included. According to some researches, this acid, besides of improving the quality, it can increase the egg production and weight. In addition, it reduces the quantity of cracked eggs and food intake. In order to contribute with more information, this experiment was developed. Concentrations of 100; 150 and 200mg/kg of ascorbic acid were added to rations of laying hens during 60 days, with the objective of determining the influence of ascorbic acid on the quality of eggs kept under room temperature conditions (26.7 ± 2.2°C and 60 ± 5% moisture) for a period of 28 days. A total of 1440 eggs were used, being 720 of white shell and 720 of brown shell. Egg quality was determined by Haugh unit and yolk index, every 7 days. The obtained results allowed to conclude that ascorbic acid, independent on the level of supplementation, was not enough to decrease.
