introduction : antibiotic feed additives have long been used as growth promoters (10). however, consumers and health authorities increasingly dictate that the use of synthetic food additives should be phased out and, where possible, only natural products should be used. hence, alternatives from natural sources with potential antioxidant activity are investigated (16). olive leaves are a good so...

To determinate the effect of chromium-methionine level in diet on hatchability of Japanese quail in dry tropic weather under temperaturecontrolled in summer season, a completely randomized design experiment was conducted. Thousand two hundred eighty Japanese quail (960 females and 320 males), they were divided in 160 groups of eight (six females and two males), and were allocated in wire cages ...

A total of 240 Japanese quail chicks (1 d old) were used in a 42-d trial to study the effects of Artichoke leaf powder and vitamin E on growth performance and meat quality. This experiment was performed as a completely randomized design with 4 replicates of 15 quails in each, using a 4×2 factorial arrangement with diet and gender as the main effects. Four dietary treatments were formulated by a...

the study was conducted to determine the effect of varying protein levels and preservation method on external egg qualities of japanese quails. a total of 180 birds were randomly allotted into three dietary treatments in a completely randomized design (crd) replicated six times. a factorial arrangement of 3 × 4 × 4 which involves 3 protein levels (15, 20 and 25% crude protein), 4 storage method...

The proximate composition, pepsin digestibility, gross energy and macro mineral contents of 12 composite samples of poultry offal meal produced in Sri Lanka were analyzed. The average dry matter, ash, crude protein, crude fiber, ether extract, in vitro pepsin digestibility and gross energy of poultry offal meal were 92.3, 6.9, 48.9, 2.1, 32.4, 83.8% and 23.6 MJ kg, respectively. The average Ca,...

We evaluated messenger RNA (mRNA) expression of the growth-hormone (GHR) and insulin-like growth factor (IGF-1) genes in 28-day-old Japanese meat quails fed diets containing 0, 8, or 12% dietary glycerol in substitution of corn. Total RNA was extracted from the breast muscle and the DNA was amplified with specific primers using real-time PCR. Feed conversion ratio and feed intake were evaluated...

Background: Maggot meal, popularly magmeal is a core product consisting of dried defatted larvae that ground into high protein meal. It potential alternative for fish replacement in the diet quails. Methods: A study on 240 Japanese quail birds from day old to six week age was conducted at Poultry Research Station, Madhavaram Milk Colony, Chennai with supplementation during year 2015-16. The wer...

In order to investigate the effect of different levels lavender essential oil and bacitracin methylene disalicylate antibiotics on performance, carcass traits, some blood parameters, small intestinal tissue morphology microbial population in Japanese quails, a study was performed 400 pieces quail per day. The treatments included group consuming basic diet without any additives as (control) anti...
