Aim: In the present study, egg quality traits of endangered Nicobari fowl and its crosses (Nicorock and Nishibari) were evaluated under intensive (deep litter) as well as backyard system, in the regions of Andaman and Nicobar Islands, India. Materials and Methods: Fresh eggs (15) of all the three genetic groups of birds were collected randomly from institute farm (intensive system) and from far...

1. A total of 257 farmers with free ranging laying hens (organic and conventional) in Switzerland, France and The Netherlands with 273 flocks were interviewed to determine the relationships between the genotype of the hens, management conditions and performance. 2. Almost 20 different genotypes (brands) were present on the farms. In France, all birds were brown feathered hens laying brown egg...

Egg storage longer than 7 d is associated with a delay in hatch time and a decline in hatchability and chick quality. Prestorage incubation is suggested as a method to reduce the negative effects of prolonged storage times by altering the developmental stage of the embryo, but earlier research has shown that prestorage incubation can both be detrimental and beneficial for hatchability. The reas...

An experiment was conducted with Hy-Line W-36 hens to evaluate the Val requirement in a corn-soybean meal diet. Eight experimental diets were fed with Val levels of 0.700, 0.665, 0.630, 0.595, 0.560, and 0.525%. A positive control (0.765% Val) was fed. Egg production (EP) was increased by addition of Val to 0.630%. Egg weight (EW) was increased by addition of Val to 0.655%. Broken-line regressi...

a very complete index conclude a well-written, well-printed, and well-illustrated volume, which cannot fail to be of much utility for consultation on the many questions of Sanitation which are commonly cropping up from day to day, and on which an authoritative statement is required. We notice a remark appropriate to the present time outcry for eggs, " Though nutritious and digestible, they cann...

The relationship between egg size and composition (relative amounts of lipid, protein, and water) can play an important role in determining neonate size, quality, or the amount of post-hatching care observed in many reptiles. We evaluated the relationship among egg wet mass, non-polar lipid mass, water content, shell dry mass, and lean dry mass within and among seven clutches of the Diamondback...

Stool samples from 409 pre-school and school students, living in six villages of the Cajabamba and Condebamba districts, Cajamarca, Perú, were examined using wet preparations and Lumbreras' method, looking for Paragonimus eggs. Fecal and sputum samples from two children (0. 5%) of 6 and 8 year-old showed eggs of Paragonimus. One hundred and twenty freshwater crabs, Hypolobocera chilensis eigenm...

During earlier studies on vacuum concentration of liquid egg white, the phenomena of foaming during the initial stages of the process were reported. In these studies, it was also shown that no concentration took place during the foaming period that varied from test to test. To minimize the total process time, this present study was undertaken to investigate what variables contributed to foaming...

The aim of this study was to identify the optimal turning duration of Dandarawi hen incubated eggs on embryo mortality, hatchability, one-day chick weight and viability of chicks at 14 days of age. Collected eggs from Dandarawi hens at 36 weeks of age were stored for 7-d at 16°C and 75% RH and then were incubated for 21-d under standard incubation conditions using different turning durations. E...

BACKGROUND/AIMS To investigate the association between the risk of overweight and the consumption of food groups in children and adolescents. METHODS We studied 1764 healthy children and adolescents (age 6-19y) attending 16 Seventh-Day Adventist schools and 13 public schools using a 106-item non-quantitative food frequency questionnaire from the late 1980 Child-Adolescent Blood Pressure Study...
