Six different diets including two rainbow trout starters, Gammarus dry powder, shrimp dry powder, egg yolk dry powder and newly hatched Artemia were used in feeding of Caspian Kutum larvae. During a 4-week trial, larvae with a mean weight of 17.5 ± 4.7 mg were fed with three replicates and growth parameters were measured at the end of the experiment. Thirty fish in each experimental unit with...
this study was conducted to investigate the effects of dietary nigella sativa meal (nsm) on the growth performance, blood parameters, carcass characteristics, egg yolk cholesterol and meat quality in japanese quail. for this purpose 300 one-day old japanese quail chicks in a completely randomized design was used with five treatments in four replicates )containing 15 birds each(. the experimenta...

Because it serves as the cytoplasm of the oocyte and provides a large amount of reserves, the egg yolk has biological significance for developing embryos. The ovary and its hierarchy of follicles are the main reproductive organs responsible for yolk deposition in chickens. However, the genetic architecture underlying the yolk and ovarian follicle weights remains elusive. Here, we measured the y...
Chicken eggs represent an important source of protein to the growing human population and also supply repositories of unique genes that could be used worldwide. The inheritance of shank feathering trait is dominant upon non-feathering shank trait in chicken which is based on two factors: pti-1L and pti-1B that are located on Chromosomes 13, 15, and 24. Using 185 fertile eggs collected from two ...
The quality of Pharaoh quail eggs obtained at 8, 13, 18 and 23 weeks of age was evaluated. Eggs laid by the oldest quail were characterized by the greatest weight (12.2 g), length (32.6 mm), width (25.8 mm) and shell surface area (25.3 cm2). The lowest shell weight was found in eggs from the youngest quail (0.9 g), and the lowest shell proportion (8.2%) was characteristic of eggs from the oldes...
This study aims to determine the effect of using Hermetia illucens maggot in feed on internal and external quality broiler eggs.The used 80 laying hens aged 6 months which were divided into 4 treatments, 5 replications each replication consisted tails. The variables observed eggs (egg weight, egg shape index, shell thickness, weight) white yolk Haugh units, color). data obtained analyzed with a...
1. Laying hens, 225 white and 225 brown, were fed for 90 d to compare a control diet with diets containing 70, 140, 210 and 280 g/kg chia (Salvia hispanica L.) seed. 2. Hen weight was not significantly affected by diet; however, manure production was less for the hens fed on chia. 3. Egg weight and production, yolk weight, and yolk percentage were determined at d 0, 30, 43, 58, 72 and 90. 4. A ...
Avian eggshell quality is an important trait for commercial egg production, as the eggshell is the primary packaging material and antimicrobial barrier for the internal food resource. Strong eggshells are essential to ensure that eggs can reach their final destination without damage. Ovocalyxin-32 (OCX32) is a matrix protein found within the outer layers of the eggshell and in the cuticle. Nume...
The objective of this study was to investigate the effects of dietary corticosterone on egg quality. For 2 weeks hens received either control or experimental diet containing corticosterone at 30 mg/kg diet. Feed intake and egg production were monitored daily, and body weight measured weekly. Egg weights and egg quality were measured daily. Corticosterone treatment resulted in a remarkable incre...
