In this study, the effect of using gamma irradiated barley and wheat 0, 10 and 100 kiloGray (kGy) and enzyme supplementation on the egg product criterions and external and internal egg quality was examined. In this experiment, 36 weeks old, 324 Brown Nick laying hens were used for ten week. The study was a randomized complete block design with 9 dietary treatments within 6 blocks of 54 pens each 6 birds per pen. Although egg weight was not significantly affected by gamma irradiation; enzyme supplementation of barley based diet significantly increased egg weight compared to barley control group. As egg mass production was considered, enzyme and 100 kGy gamma irradiation significantly improved the egg mass production compared to barley control. The feed conversion ratio was significantly improved by using gamma irradiated barley and enzyme in barley based diets (P

Calla (Zantedeschia aethiopica (L.) K. Spreng), is a cut flower which had obtained importance in recent years, but postharvest handling is limited. Thus, in order to know the fluorescein concentration effect and pH of pulse solution on inflorescences calla postharvest, were evaluated in Teotitlan de Flores Magon, Oaxaca-Mexico, four fluorescein concentrations (0, 20, 40 and 60 %, respectively) and two pH levels (acid and alkaline) in a completely randomized design with factorial arrangement, having a total of 24 experimental units, which was established by vase life and calla inflorescence with white spathe color, immersed in a fluorescein solution adjusted as appropriate at acidic or alkaline pH, where response variables were as follows: vase life, water consumption, stem diameter, absorption fluorescein stem base and fluorescein vertical absorption by floral scape. Results indicates the increased vase life is achieved at alkaline pH by fluorescein addition of 20, 40 and 60 %, respectively. Likewise, the higher water consumption is achieved at this pH. From this research, we can conclude fluorescein can affect the calla physiology for increasing vase life. | Calla (Zantedeschia aethiopica (L.) K.
