Indigenous chickens (IC) are mainly raised by resource poor rural households in developing countries [1]. Although they are of low genetic potential compared to the commercial breeds, IC play a vital role in livelihoods of farmers and contribute significantly to food security and income [1]. IC dominates in most smallholder farms in Malawi and they are deemed less productive but appear to be ad...

Four thousands and two hundred hatching eggs were obtained from Bandarah chicken to evaluate the effect of chemical and natural eggs disinfectants and fumigation on egg weight loss, embryonic mortality, hatchability, hatch time, chick weight, and chick weight loss. Three incubation trials were done, each one contained 1400 hatched eggs and divided into fourteen treatments (100 eggs per each). F...

Using 351 one-day weighted diet records, we selected foods providing vitamins, minerals and dietary fiber according to contribution analysis (CA) and multiple regression analysis (MRA). Vitamin C was supplied by various vegetables and fruits, and carotene was specifically derived from green-yellow vegetables based on MRA as well as CA. Vitamin A was provided by green-yellow vegetables, fruits, ...

A simple procedure is described for the mechanical isolation of protoplasts of unfertilized and fertilized barley egg cells from dissected ovules. Viable protoplasts were isolated from ~75% of the dissected ovules. Unfertilized protoplasts did not divide, whereas almost all fertilized protoplasts developed into microcalli. These degenerated when grown in medium only. When cocultivated with barl...

Materials and Methods About 85% of chicken stock of India belongs to small sector which provides 50%of total egg production [1-3].Familychicken through the InternationalNetwork on Family Poultry Development (INFPD) was also committed by the Food and Agriculture Organization (FAO) as a Special Programme for Food Security (SPFS) in the developing countries including India where backyard chicken p...

Background: In the current Iranian poultry industry, antibiotics are the most frequently used additive in poultry feeds to increase productivity. The negative effects on human health, resulting from the consumption of chicken whose feeds contain antibiotics, makes finding an appropriate alternative of great importance. As a result of their nature, herbal extracts could be specifically considere...

Objective- Because little information was available in the literature about the angiogenic property of enrofloxacin, this investigation was undertaken to evaluate this aspect using an in vivomodel. Design- Experimental study. Animals- Twenty fertile chicken eggs (Ross 308) with the average egg-weight of 55 ± 0.4 g were rand...

Two experiments, which included 3 incubators, were carried out to investigate the effects of egg weight and position relative to incubator (setter) fan on embryonic mortality, second quality chicks, and fertile hatchability of broiler eggs. Three egg weight groups termed small (approximately 62.4 g), average (approximately 65.4 g), and large (approximately 68.9 g) were set in either the incubat...

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...
