Abstract The aim of the study was to evaluate the ameliorative effects of lycopene and vitamin E, administered individually and in combination, on laying hens during the hot-dry season. The dry-and wet-bulb temperature were recorded daily from 06:00–18:00 h during the 5-week experimental period. Daily and weekly hen-day egg productions, egg weight, eggshell thickness and eggshell weight were determined using standard procedures. The dry-bulb temperature (23.0°C – 39.0°C) and temperature - heat index (24.4°C − 35.0°C) recorded show that the hens were subjected to heat stress during the season. Egg production in the laying hens in lycopene (62.4 ± 1.1 %), vitamin E (62.1 ± 1.2%) and lycopene + vitamin E (62.7 ± 1.0 %) groups were higher (P < 0.05) than in controls (56.0 ± 0.8%). Eggshell was thickest in lycopene + vitamin E group (0.28 ± 0.02 mm), compared to lycopene (0.23 ± 0.02 mm) and vitamin E group (0.22 ± 0.02 mm). The thickness was lowest (P < 0.05) in control hens (0.18 ± 0.02 mm), compared to any other group. Similarly, control laying hens recorded the least (P < 0.05) in eggshell weight (6.7 ± 0.02 g), compared to the weights recorded in lycopene + vitamin E, lycopene and vitamin E groups (7.3 ± 0.24 g, 7.3 ± 0.3 g and 7.2 ± 0.3 g, respectively). In conclusion, lycopene and vitamin E ameliorated the risk of adverse effects of heat stress by increasing hen-day production, eggshell weight and eggshell thickness during the hot-dry season.

Vitamin E Supplementation

1. Experiments were conducted to study the effects of dietary vicine (2, 6-diamino-4, 5 dihydroxy pyrimidine-5 (β-D-glucopyranoside)) and supplemental vitamin E on the performance of laying hens and growing chicks.2. Chicks fed on diets that contained vicine had similar growth rates but slightly higher levels of spontaneous haemolysis of erythrocytes than birds fed on a control diet.3. Vicine when fed to laying hens had a very dramatic effect. It depressed food consumption, egg weight, fertility and hatchability of eggs, packed cell volume and erythrocyte haemoglobin levels and led to increased liver weights, liver glutathione levels, liver and plasma lipid levels, plasma lipid peroxide levels and erythrocyte haemolysis in vitro. Liver protein and plasma vitamin E:lipid levels were not altered. Vitamin E supplementation slightly increased egg weights, markedly improved fertility and hatchability of eggs and lowered liver weights and lipid levels but did not affect the other factors examined.4. It is concluded that vicine which was isolated from faba beans (Vicia faba L.) has a marked influence on the metabolism of the laying hen and only a slight effect on the growing chick. Vicine or its metabolites or both cause peroxidation of cellular components which result in abnormal lipid transport or synthesis or both, increased fragility of erythrocytes, and reduced fertility. These effects are overcome to varying extents by supplemental vitamin E.

It was investigated in a small-scale study using a climate-controlled room at IAPGR, Roslin, that the effects of feeding a high level of supplemental vitamin E (500 mg/kg) on egg production and plasma concentrations of egg-associated metabolites in laying hens subjected to a short exposure (7 days) to a moderate heat stress (temperature of 32°C). The study showed, on small group sizes (12 birds / group), that in control birds (fed 30 mg supplemental vitamin E/kg), this degree of heat stress depressed egg production by about 30%. In the birds receiving the high level of vitamin E, egg production was maintained at levels very close to those prior to the heat stress. The objective of this experiment was to confirm in a larger scale the effects of high levels of dietary vitamin E on egg production of hens exposed to a chronic heat stress and during a period of recovery at thermoneutral temperatures.
