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.

Trace Element Deficiency

The Altai Region along with the regions of the Siberian Federal District belongs to the zone with trace element deficiency including iodine deficiency. The research goal was to study the effect of iodine on edible egg quality of laying hens of the Rodonit cross. At the final stage of egg-laying, 4 groups of 4 laying hens were formed. No iodine was administered to the hens of the 1st control group. Starch-based iodine product was administered to the birds of the 2nd, 3rd and 4th trial groups into the lower third of the neck, under the wing and into the rump area in a dose of 1.5 mg per head. The egg production intensity in the trial groups was higher by 21.3-28.8%. Egg weight in the 1st control group was 65.6 ± 1.33g which was lower than that in the trial groups by 4.4% (2nd group); 3.7% (3rd group) and 1.5% 4th group). All eggs belonged to “select” grade. The 3rd and 4th trial groups had less egg white by 3.8 and 2.7%; the egg-yolk content increases in the eggs of the 2nd, 3rd and 4th trial groups by 1.2%, 9.4% and 2.4%, respectively, and the eggshell weight by 1.2-9.4% as com-pared to the control. The ratio of egg white and egg-yolk weight in the eggs of the trial groups was lower than in the control group by 9.38-19.29%, but the ratio of egg-yolk to egg white was by 10.4-23.9% higher. The following indices were higher in the trial groups as compared to the control: egg white index -by 1.4-17.1%; egg-yolk -by 3.2-6.4%; Haugh unit -by 7.2-11.1%; eggshell thickness -by 3.9-8.3%. The best results were obtained with the administra-tion of iodine to the hens in the region of the lower third of the neck. The enrichment of the body of laying hens of the Rodonit cross with iodine makes it possible to obtain the profitability of edible egg production at the level of 28.6-41.0%.

Despite the modern surgery progress and success, the achievements of asepsis and antisepsis, as well as rather broad possibilities of antibacterial, infusion and detoxification therapy, the incidence of peritonitis and mortality from it remain at a high level.The aim of the study was to clarify the significance of the activity of Kupffer cells in the regulation of total cholesterol in the liver and blood lipoproteins, the level of iodine-containing thyroid hormones in the blood and the body temperature in rats with experimental peritonitis.It was found that in the conditions of experimental peritonitis in rats, secondary atherogenic dyslipoproteinemia develops and the level of iodine-containing thyroid hormones in the blood decreases. Kupffer cells and nitrogen monoxide are involved in the changes in the content of total cholesterol, lipoproteins, the level of iodine-containing hormones in the blood plasma and the body temperature during peritonitis. A decrease in the activity of Kupffer cells in peritonitis, apparently, plays a compensatory role and prevents the development of secondary dyslipoproteinemia.

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.

The aim of this study was to evaluate the use of a Madagascar cockroach (Gromphadorhina portentosa) meal in the feed of cockatiels (Nymphicus hollandicus) in captivity and its influence on the reproductive characteristics of these birds. Twelve pairs of birds were used during two subsequent reproductive cycles of 130 days each, with time divided into four phases: laying, incubation, rearing of chicks until 30 days of age, and return to the new laying phase. The pairs were divided into two groups: a control group, which received a commercial diet for psittacines + a mixture of seeds, and a test group, which received the same diet as the control group except for the addition of a Madagascar cockroach meal in a ratio of 14 g of commercial food to 1 g of cockroach meal (6.6%). After hatching, chicks remained with their parents until 30 days of age. Subsequently, the chicks were transferred to another room and monitored until the 90th day of life. The inclusion of cockroach meal did not influence (p > 0.05) the intake of commercial food and mixture of seeds during the reproductive phases evaluated, except for feed intake, which was increased relative to control values (p = 0.02) in the return-to-laying phase. Yolk cholesterol content, egg width and egg shape index were increased with the inclusion of the cockroach meal, whereas the number of days to return to the new laying phase was reduced compared to the control (p = 0.02). The number of eggs laid decreased (p < 0.05) with the inclusion of the cockroach meal; however, the percentage of hatching was higher in the test group than in the control group (p < 0.05). No significant effect (p > 0.05) of dietary treatment was observed on the number of viable chicks at 1, 30 and 90 days of age or on the contents of most fatty acids present in the yolk. The findings of this study indicate that a Madagascar cockroach meal can be used as an alternative feedstuff in the diets for cockatiels and can lead to minor improvements in reproductive characteristics when replacing 6.6% of the commercial pelleted diet.

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 &lt; 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 &lt; 0.05) in egg albumen index, egg shell index and Haugh unit. There was a significant (P &lt; 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 &lt; 0.05) with increasing levels of dietary garlic powder. Plasma cholesterol (P &lt; 0.05) and tri-glyceride (P &lt; 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 the study was to determine whether a diet with an addition of black cumin seeds (BCS) can be used in functional egg production. At 8 weeks of age, a flock of 96 female quails was divided into 3 groups. The control group received their standard feed (0 BCS). The diet offered to the test groups was supplemented with BCS in the amount of 20 and 50 g · kg–1, respectively. Dietary BCS supplementation decreased feed intake and improved feed efficiency. Egg yolk of the quail groups treated with BCS in their diet had by a lower percentage of SFA and an increased level of UFA. A significantly increase was observed in the level of PUFA, especially in PUFA n-6. The health-promoting properties of the product were indicated by the fact of a considerable reduction in the yolk cholesterol level. Unfortunately, n-6/n-3 ratio increased in the groups offered the BCS-supplemented diet and under these circumstances eggs obtained from quails receiving BCS in the diet did not meet the requirements of functional food.

A feeding trial was carried out for five 28-day periods with diets containing 0.0, 0.04, 0.2 and 0.4% of saponin (Sarsaponin) in either the presence or absence of dietary cholesterol to study the saponin-cholesterol interaction and also to determine the effects on the levels of yolk cholesterol and the performance of single-comb White Leghorn laying hens (44 wk of age). No significant differences were found in the levels of egg yolk cholesterol; however, egg production and feed intake were reduced by feeding saponin. These adverse effects on the layer performance were counteracted or completely disappeared when 0.5% cholesterol was fed simultaneously to the laying birds. Egg yolk cholesterol contents were raised by dietary cholesterol but were not influenced by the dietary presence of saponin. In the second trial, layers were given a dose of 14C-cholesterol emulsified in corn oil with and without 0.48 g saponin in order to determine the specific effect of saponin on dietary cholesterol absorption and deposition into egg yolk. Dietary saponin increased the excretion of 14C-cholesterol from 8.6 to 65.8%, decreased egg deposition from 31.5 to 16.6% and decreased serum radioactivity by 39.2%. Thus, it was concluded that dietary saponin reduced cholesterol retention and transfer of dietary cholesterol to egg yolk, but failed to lower cholesterol content in egg yolk. Key words: Saponin, egg cholesterol, 14C-cholesterol, laying hens
