This study was conducted to investigate the effects of garlic powder on the performance, egg traits, egg cholesterol and serum parameters of laying Japanese quails. One hundred and twenty 10-weeks-old quails were allocated to four dietary treatments. Quails were caged individually and fed diets supplemented with 0 (control), 1, 2, 4% garlic powder for 12 weeks. There were significant (P < 0.05) differences among the diets in feed consumption, feed efficiency and egg production as averaged over 12 weeks. The better values for these parameters were obtained from the 1% garlic powder supplemented group. Garlic powder addition did not significantly affect egg yolk index, egg shell weight and egg shell thickness. However, there were significant differences (P < 0.05) in egg albumen index, egg shell index and Haugh unit. There was a significant (P < 0.05) reduction in the egg yolk cholesterol concentration when the dietary level of garlic powder was increased from 0 to 4 g/kg. Plasma high density lipoprotein (HDL) cholesterol concentrations increased (P < 0.05) with increasing levels of dietary garlic powder. Plasma cholesterol (P < 0.05) and tri-glyceride (P < 0.05) concentration decreased with garlic powder supplementation. It was concluded that garlic powder in the diet of laying quails reduced the plasma and egg yolk cholesterol concentration.

The aim of this study was to investigate the effects of different levels of alfalfa meal on performance, egg quality, egg yolk cholesterol and hatchability parameters of quail breeders. In this trial a total of 90 Japanese quail breeders (30 males, 60 females), 10 weeks old was distributed 5 experimental groups randomly. Each experimental group consisted of 6 replicates of 3 quails (1 males, 2 females) in each. During the 12 weeks experiment period, birds were fed with 5 dietary groups based on corn and soybean meal and containing 0 (control), 10, 20, 40 and 80 g/kg alfalfa meal. Feed and water were offered ad-libitum throughout the experiment. The different dietary levels of alfalfa meal had no significant effect on body weight change, egg production, egg weight, egg mass, feed conversion ratio, egg shell breaking strength, egg yolk triglyceride, fertility, hatchability of fertile eggs or hatchability of eggs set. The feed intake was decreased with 10 or 20 g/kg alfalfa meal levels in the diet. The eggshell weight was best in quails fed 20 g/kg alfalfa meal, and the egg yolk cholesterol was the lowest in quails fed 40 g/kg alfalfa meal. According to the results of this study the addition of 40 g/kg alfalfa meal in laying quail diets decreased the egg yolk cholesterol levels without adverse effect on performance.

Supplementation of the basal ration of laying hens with 0.001, 0.005, and 0.01% neomycin sulphate did not produce any significant changes in the weight of the hens, their eggs, or egg yolks, nor did it alter egg production. Supplemental neomycin caused no significant changes in levels of plasma cholesterol. Plasma and yolk lipid levels varied considerably within as well as between groups of hens. Plasma squalene/plasma cholesterol and yolk squalene/yolk cholesterol ratios were approximately the same, indicating the presence of 250 times more cholesterol than squalene. Plasma squalene/yolk squalene and plasma cholesterol/yolk cholesterol ratios showed that both components were approximately 13 times more concentrated in the yolk than in the plasma. The variable plasma cholesterol levels for rats, rabbits, mice, human beings, as well as the laying hen, treated with neomycin, are suggestive of species differences in response.

The experiment designed to study the influences of nutritional eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids (FA) on performance, egg yolk fat characteristics and FA profile in laying hens. From 30 to 36 weeks of age, 180 laying hens were allotted randomly to 2 dietary treatments, each of 6 replicates (15 birds for each replicate). The control diet was supplied with soy oil while the experimental diet was supplied with EPA and DHA to create 2 different ratio of n-6 to n-3 FA (18.8:1 and 5:1, respectively). The egg production % was recorded daily. The eggs were weighed to estimate egg mass. Also, feed consumption was recorded daily and the feed conversion ratio (FCR) was estimated. The FA profile of egg yolk was determined in the last week of the experiment. The dietary EPA and DHA resulted in significantly higher egg production (76.89 versus 67.23%), weightier egg mass (42.46 versus 37. 72 g) and lower FCR (2.49 versus 2.72) than the control. Also, supplying the dietary EPA and DHA was reflected in increasing of total polyunsaturated and n-3 FA in the eggs. Moreover, reducing the ratio of n-6 to n-3 FA to 5:1 decreased egg triglycerides, total cholesterol and cholesterol associated with low density lipoprotein and very low density lipoprotein. In conclusion, supplying EPA and DHA in the diet of laying hens positively influences performance, egg yolk FA profile and cholesterol. Practically, EPA and DHA could be used in laying hen diets to improve their performance and enhance public health of egg consumers.

This study was conducted with the objectives to determine the effects of licorice root powder (Glycyrrhriza glabra) on performance, serum parameters, egg yolk cholesterol and antioxidant capacity in laying Japanese quail. Two hundred and forty 10-wk-old Japanese quails were randomly assigned to four dietary groups, each one four times replicated with fifteen quails per dietary groups. Control group fed the basal diet; other groups were fed basal diet supplemented with 0, 0.5, 1.0 and 1.5% licorice root powder. There were no significant differences in terms of final live weight, feed intake, feed conversion ratio, egg weight, serum cholesterol, triglyceride and High-Density Lipoprotein (HDL) concentration between treatment groups. Egg production was higher in control group and 0.5% licorice root powder supplemented groups. 1.0% licorice root powder supplemented group had lower egg production rate. Licorice root powder supplementation decreased Low Density Lipoprotein (LDL) concentration and increased glucose concentration significantly. Licorice root powder supplementation increased total antioxidant status (TAS) and reduced total oxidant status (TOS) and oxidative stress index (OSI). It was concluded from this study that supplementation of licorice root powder at the level of 0.5, 1.0 and 1.5% to the feed of laying quails had no adverse effects on performance. Licorice root powder supplementation can be used to reduce cholesterol level and increase antioxidant status in quails.

Background: An economically active population refers to people involved in any economic activity, such as agriculture, livestock, or industry. This activity can supply benefits to its owners and may generate the growth of small businesses. Our study presents a qualitative analysis of the egg production in Ecuadorian Andean communities (Tzimbuto, Bayushig "La Liberad," and La Victoria "Pusuca.") Methods: Analysis was performed using a random sample of 81 hens and 29 eggs obtained from 65 producers, belonging to 50 farming families at the Utopia Community Fair. Zoometric characterization of the hens was carried out according to FAO protocols, and egg yolk quality, egg width and weight, and egg shell weight and thickness were calculated. The 65 producers were interviewed to answer questions pertaining to selling eggs, costs of production, and realized profit. The profit/cost indicator was calculated from the ratio of expenditure (egress) and total revenue of egg sales. Results: 84% of surveyed participants indicated that they purchase eggs for their nutritional value, 12% because the animals are raised with organic food, and 4% showed preference for the eggs’ special flavor. The quality analysis of the eggs sold at the Fair demonstrated that the average weight of the eggs was 47.24 g; the length was 55.24 mm; and the width was 41.66 mm; weight and thickness of the shell were 4.90 g and 0.42 mm, respectively. The color of the yolk had a brightness of 57.62 L*, 5.53 a* for red/green tones and 47.15 b* for yellow/blue tones. The costs to produce the eggs for the Fair was US$0.21 with a profit/cost of US$0.04 per egg; the unit sale price is US$0.25. Conclusions: 84% of surveyed participants indicated that they purchase eggs for their nutritional value, revealing the need to train the communities toward more efficient egg production.

A total of one hundred and fifty (150) Nera ser-linked layer strains (32 weeks of age) were used to investigate the performance response, blood plasma and egg yolk cholesterol status of hens fed cassava roul sievate (CRS) bused - diets. CRS was used to replace wheat offal at 0, 5, 10, 15 und 20% respectively, resulting in five dietary treatments. Each treatment had 3 replicates with each replicate group having five hirds. The experiment lasted for 10 weeks. No significant effect of diers was noticed in the body weights, weight gain and daily feed intake. Fced conversion per dozen eggs, hen-day egg production and total egg produced significantly declined as CRS levels increased from 0 to 20% in the diets. Diets with 20% CARS had the poorest performance. However, the blood plasma, egg yolk and egg cholesterol concentrations were reduced significantly (p< 0.05) with increased level of CRS Dietary treatment with 20 % CARS had the lowest (P< 0.05) cholesterol concentration. Inclusion of up to 20% CRS led to 35% reduction in plasma total cholesterol, while 18 and 17% reductions were obtained in the egg yolk total cholesterol and total cholesterol per egy respectively. Replacement of up to 10% (w/w) wheat offal by CRS is therefore recommended 10 effectively reduce cholesterol content of the plasma ,egg yolk and whole egg by 20%, 10% and 17 % respectively at performance level that are comparable with that of the control group.

A total of 240 white Shaver laying hens from 22 to 34 weeks of age were assigned to 3 treatments and 5 replications. The treatments included: i) Conventional (hens were kept in experimental building without access to outdoor area and fed with the conventional diet), ii) Semi-organic (hens were kept in experimental building with access to outdoor area and fed with the organic diet plus amino acids and vitamin-minerals supplement), and iii) Organic (hens were kept in experimental building with access to outdoor and fed with the organic diet). The results showed statistically significant differences in the feed intake, egg production, egg mass, egg weight, and change body weight(g) means among the treatments (p < 0.05). The hens kept in the organic treatment had fecal highest contain of oocytes coccidia (p < 0.05). The yolk color index and shell strength in the organic treatment significantly increased in comparison with that of other treatments (p < 0.05). The highest HDL was in the semi-organic and organic treatments (p < 0.05). The lowest egg yolk cholesterol concentration was found in hens kept in the semi-organic and organic treatments (p < 0.05). It is concluded that organic production system is useful for improving egg quality.

     The effect of garlic supplementation on egg traits and productive performance of laying chickens have been widely studied but little information is available on the basis of strains while the issue of level of inclusion is an ongoing debate. This study investigated the effect of garlic supplementation on the productive performance and egg traits of Isa-brown, a specific strain of laying hen. Forty eight Isa Brown layers were randomly selected and allocated to four dietary treatments; each treatment had twelve layers consisting of three in a cage compartment and in four replicates. The treatments consisted a control, 0.5, 1 and 2 % garlic powder supplemented diets and fed to the layers for twelve weeks. Data were collected on growth parameters, egg traits and cholesterol contents. The dietary treatments significantly (p<0.05) reduced the body weight, feed intake, egg weight and hen-day egg production to the least values at the 2 % level of garlic powder inclusion but the feed efficiency was not affected. Garlic supplementation significantly (p<0.05) increased the albumen index, shell index, shell weight, Haugh unit and yolk cholesterol. The 1% garlic inclusion level gave the highest albumen index and Haugh unit while the highest shell index at 2 % garlic supplementation was due to significant (p<0.05) reduction in shell weight. Garlic significantly (p<0.05) decreased the egg yolk cholesterol but did not affect the yolk index and the yolk weight. Garlic supplementation in Isa Brown layers’ diet should not exceed 1 % inclusion in order to avoid reduced productive performance and egg quality.
