Two artificial diets developed for rearing Lygus spp., a fresh yolk chicken egg based-diet (FYD) and a dry yolk chicken egg based-diet (DYD), were evaluated as an alternative food source for rearing the southern green stink bug, Nezara viridula (L.) (Heteroptera: Pentatomidae). Survival to adult was 97.3 and 74.67%, respectively, on the fresh and dry yolk diets. Insects fed FYD had 100% surviva...

We conducted 2 consecutive experiments to verify whether adult captive Greater rheas (Rhea americana) could select diets differing in nutritional and energetic content, and to evaluate the effect of those diets on egg production and hatchability. From August to January, animals were offered four diets: processed feed for rheas (diet 1), diet 1 + soybean (diet 2), processed feed for chicken (die...

1. Experiments were conducted to study the effects of dietary vicine (2, 6-diamino-4, 5 dihydroxy pyrimidine-5 (beta-D-glucopyranoside)) and supplemental vitamin E on the performance of laying hens and growing chicks, 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...

The West Indian sweetpotato weevil Euscepes postfasciatus (Fairmaire) (Coleoptera: Curculionidae) is a major pest of sweetpotato Ipomoea batatas (L.) Lam (Solanales: Convolvulaceae) in some countries. In order to improve mass-rearing for an eradication program employing the sterile insect technique (SIT), optimal population density of E. postfasciatus in an artificial diet was examined. Six pop...

The reproductive traits of the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae) were investigated and analyzed by different analytical methods. Simple statistical analysis showed relatively higher mating rates maintained from 21:00 to 2:00, thereafter dropping to a minimum at about 18:00. Mating rates were affected by female and male age. Mating was most likely to take plac...

An experiment was conducted to evaluate the efficacy of intra-amnion administration of different doses of ascorbic acid (AA) on hatchability, growth performance, blood metabolites, jejunal morphology, and tibia breaking strength in 36h post hatch fasted broiler chickens. Two hundred eighty-eight Ross-308 fertile eggs at the 15thday of incubation were divided into four treatment groups, each con...

a total number of  5520 female and  480 male breeders (arbor acres plus) at 42wks of age  were used in a 10-week-trial to investigate the effect of an enzyme complex on  the quality  and quantity of egg production as well as hatchability of broiler breeders fed a corn-soybean meal diet. there were two dietary treatment groups: a control group fed on a corn-soybean based diet, and the multi-enzy...
