EFFECTS OF CAFFEINE ON FECUNDITY, EGG-LAYING CAPACITY, DEVELOPMENT TIME AND LONGEVITY IN DROSOPHILA-PROSALTANS

Considering the factor lysine (Table 2), it is observed that increasing dietary amino acid suggests a linear increase (P = 0.07) on shell weight (Table 2) when birds are at 60 weeks

Treatment 4 (2% lysine + 0.025 % enzyme) significantly increased number of eggs, egg mass, egg production, body weight gain and daily feed intake (P<0.05).. EN: number of eggs;

Dietary perlite supplementation has no significant effects on shape, yolk, and albumen index and no negative effect on performance and egg quality traits, except at 2%

Table 2 - Egg weight (EW), lay percentage (LP), egg mass (EM), feed intake (FI), feed conversion ratio per dozen eggs (FCR/dz), feed conversion ratio per kg egg (FCR/kg), and

Since ionomycin by itself activates mature eggs, we have used the GV stage oocytes briefly exposed to the ionophore, and followed the consequences in meiotic maturation,

obliqua obtained from mango presented the least longevity and greatest fertility at 18 days compared with the other species studied; (5) males and females from the three

In this work we aimed to evaluate the ability of different strains of Trichogramma pretiosum Riley in parasitize and develop on artificial host eggs by using a standard diet..

The results showed that the light phase of a LD12:12 regime had the largest number of females not laying eggs (15 females, or 25%), whereas all females laid in the dark phase
