The lady beetle, Curinus coeruleus (Mulsant), a biological control agent of the coconut mealybug, Nipaecoccus nipae (Maskell) and the psyllid, Heteropsylla cubana Crawford, was examined for its ability to consume Aedes albopictus (Skuse) eggs in the laboratory. Most C. coeruleus larvae in this test preyed on A. albopictus eggs (75% for the 2 and 3 instar and 71% for the 4 instar). The 2 and 3 i...

The purpose of the study was to investigate potential feeding laying hens with ground flax, a combination flax cake and oil in production eggs enriched omega-3 fatty acids. experiment set up using 192 divided into 4 groups: control group; group fed flaxseed (10%) + (2%); 5% 10% flax. Each had 8 cages housing 6 hens, that is, total 48 per group. Haugh unit values, fat content, Thiobarbituric aci...

This study was undertaken to determine the effects of storage period and egg weight of hatching eggs of Japanese quails on fertility, hatchability results. Eggs were obtained 150 females quails, all at 15 weeks of age. A total of 1942 hatching eggs were separated into 3 groups as light-weight (9.50-10.50 g), medium-weight (10.5111.50 g), and heavy-weight (11.51-12.50 g). Based on storage period...

The eggs of the stored grain pests, Tribolium castaneum (Herbst), T. confusum (Duval) (Coleoptera: Tenebrionidae) and Cadra cautella (Walker) (Lepidoptera; Pyralidae) belonging to three age groups, 1, 2, and 3 days-old, were exposed to ultraviolet (UV) radiation with 254nm wavelength (UV-C) for different durations to determine irradiation effects on egg-hatching and adult emergence. An increase...

Soybean protein is one of the least expensive sources of dietary protein [3]. Soybean protein is considered to be a good substituent for animal protein [4], and their nutritional profile ex‐ cept sulfur amino acids (methionine and cysteine) is almost similar to that of animal protein because soybean proteins contain most of the essential amino acids required for animal and human nutrition. Rese...

Research was conducted to compare the effectiveness of electrolyzed oxidative (EO) water applied using an electrostatic spraying system (ESS) for killing populations of bacteria that are of concern to the poultry industry. Populations of pathogenic bacteria (Salmonella typhimurium, Staphylococcus aureus, and Listeria monocytogenes), and the indicator bacterium Escherichia coli were applied to e...

In the US farmers often market pastured poultry eggs for a premium price, claiming animal and human health benefits. We examined how moving pastured hens to forage legumes or mixed grasses influenced hen (Gallus gallus L.) egg omega-3 fatty acids and concentrations of vitamins A and E. We also compared the eggs of the pastured hens to those of hens fed a commercial diet in cages. We used a cros...

This study was conducted to determine the effects of different prestorage incubation (PRESI) times of 0, 3, 6 and 9 h on the hatchability of guinea fowl eggs stored for 14 d. A total of 80 eggs were assigned to each of the four PRESI treatments. PRESI-3h, PRESI-6h and PRESI-9h eggs were placed in an incubator at 37.5°C and 65% relative humidity for 3, 6 and 9 h, respectively, before storage wit...
