The study aimed to assess the effects of different dietary Silybum marianum (SM, milk thistle) powder levels on growth performance, productivity, immunity, small intestine, haemato-biochemical parameters, meat quality, and egg and carcass characteristics of laying quails. The experimental subjects consisted of one hundred and eight 43-day-old quails divided into 3 treatments (0, 0.75, and 1.

Immunomodulatory Effects of Natural Feed Additives for Meat Chickens.

Broiler chickens are increasingly kept in large numbers in intensive housing conditions that are stressful, potentially depleting the immune system. With the prohibition of the use of antibiotics in poultry feed spreading worldwide, it is necessary to consider the role of natural feed additives and antibiotic alternatives to stimulate the chickens' immune systems. We review the literature to describe phytogenic feed additives that have immunomodulatory benefits in broilers.

A Comparison of the Effects of Raw and Processed Amaranth Grain on Laying Hens' Performance, Egg Physicochemical Properties, Blood Biochemistry and Egg Fatty Acids.

In order to investigate the effects of using different levels of either raw or processed amaranth () grain on performance productivity, egg physicochemical properties, blood biochemistry and egg fatty acids, a trial was conducted using 168 Hy-line W-36 laying hens (67 week of age) in a completely randomized design with seven treatments and six replications of four birds for eight weeks. The trial treatments included the control group receiving no amaranth and the test groups receiving 5, 10 and 15% of raw or autoclaved (120 °C for 5 min) amaranth grain based on dry matter. The results showed that the use of processed amaranth up to the level of five and ten percent of the diet compared to raw amaranth resulted in a better performance than the control group ( < 0.

Effect of Dietary Amaranth () Supplemented with Enzyme Blend on Egg Quality, Serum Biochemistry and Antioxidant Status in Laying Hens.

A feeding trial was performed to assess the effects of dietary raw amaranth () grain (RAG), with or without an enzyme blend, on the productive performance, blood biochemistry, and antioxidant status in laying hens. The trial was conducted following a completely randomized design by factorial method, including five levels of RAG (0, 10, 20, 30, and 40%, respectively) and two levels of enzyme blend (0 and 0.025 %).

Effects of Using Processed Amaranth Grain with and without Enzyme on Performance, Egg Quality, Antioxidant Status and Lipid Profile of Blood and Yolk Cholesterol in Laying Hens.

The objective of this study was to investigate the effects of feeding Amaranthus hybridus chlorostachys grain (AG) with (+E) and without enzyme (−E) on performance, egg quality, antioxidant status and lipid profile of blood serum and yolk cholesterol in laying hens. A total of 960 white leghorn (Hy-line W-36) commercial layers (56 weeks) were divided into 10 groups with 8 replicates per group (12 birds per replicate, including 3 adjacent cages with 4 birds each). A completely randomized design was implemented with a 5 × 2 factorial arrangement of treatments consisting of five levels of AG (0, 100, 200, 300 and 400 g/kg) and two levels of multienzyme complex addition (0 −E and 0.

The effects of peppermint ( L.) and chicory ( L.) in comparison with a prebiotic on productive performance, blood constituents, immunity and intestinal microflora in broiler chickens.

A total of 320 one-day-old broiler chickens were used in a 42-day feeding trial to evaluate the effects of peppermint ( L.) and chicory ( L.) in comparison with a prebiotic on-growth performance, blood constitutes, immunity and intestinal microflora.

Biomedical evaluation of antioxidant properties of lamb meat enriched with iodine and selenium.

The article presents a study of the antioxidant properties of meat from lambs that received organic forms of iodine and selenium during growth. This meat was included in diets of laboratory animals using a model of acute toxic hepatitis. The experiments resulted in developing and testing a technique that was effective in enriching lamb with bioorganic elements of iodine and selenium and contributed to the activation metabolism in the bodies of animals consuming the meat.

Effects of feeding of vitamin E or vitamin C on egg hatchability, performance, carcass traits and immunity in broiler chickens.

The effect of feeding of different levels of vitamins C and E on egg hatchability, immune response, growth and carcass traits of broiler chickens were investigated. A total of 672 fertilized eggs were assigned to one of eight experimental groups having three replicates with 28 eggs as follows: (1) negative control (not injected); (2) positive control (injected with 0.2 mL deionized water); (3) vitamin C at 1 mg; (4) vitamin C at 3 mg; (5) vitamin C at 6 mg; (6) vitamin E at 0.

[Demonstration and characteristics of the perinucleolar zone of the nucleus--a new morphological criterion of the nucleolar test system].

A dynamic structure of interphase nucleus--perinucleolar zone has been detected and studied in cell systems on high-level transcription and proliferation activity by means of light and fluorescent microscopy methods. A new light-microscopic level classification of nucleoli taking into account the structure of this zone is introduced. The percentage of nucleoli type distribution may be used as criterion of tissue synthesis activity.

[The nucleolus as a possible site of endoplasmic reticulum formation].

Complex investigations of plant and animal cells showed the nucleolus as a compartmental pulsatile system with the cycle of about one hour. Two main constitutions of the nucleolus are revealed by vital cytochemical methods: lipid-positive and lipid-negative ones. A new model of transcription is suggested.

[Localization of the fluorescent portion of the Y-chromosome in interphase nulcei of human embryonic kidney cell cultures].

The localization and frequency of accurrence of Y-chromosome fluorescent bodies in interphase nuclei in the cellular culture of 4-months male and female human embryos, were studied with fluorochromine method with quinacrine dehydrochloride. In cellular cultures of male embryonic kidney the frequency of Y-chromatin was about 50%. The Y-chromosome structural connection with nuclear membrane and nucleolus was demonstrated.

[Stereoscopic study of chromosome arrangement in the cell cycle. II].

The results obtained testify to the dependence of the interpretation of the interphase nucleus structure on the nucleus axis orientation respective to preparation plane. Variations in arrangement of nucleolus and perinucleolar vacuole with respect to the achromatic pole and centromeric ring are demonstrated.
