Full textThe objective of the work: to analyse antioxydant lycopene and santoquin influence for laying hens and quality of eggs productivity, using rapeseed oil in the feed. The tasks of work:1. To set antioxydants Lycopene and Santoquin influence for laying hens and quality of eggs productivity, using rapeseed oil in the feed. 2. To set antioxydants Lycopene and Santoquin influence for egg qualitative parameters, using rapeseed oil in the feed. 3. To set and to analyse antioxydants Lycopene and Santoquin influence for sensoring egg parameters, using rapeseed oil in the feed. Methods of the work: research. The test were made by approved methodology. Feeding test was performed on thirty 30 weeks old Lohman Brown cross laying hens, which were divided into 3 groups. Each group consists of 10 hens. Lohman Brown laying hens were feeded with bulky compuonds feeds with addition of rapeseed oil (control group). Laying hens of a group I were fed feeds containing 4 percentage rapeseed oil + lycopene (0.5 g / kg), and group II - 4.5 percentage rapeseed oil + santoquin (0.15 g / kg). During the test laying hens were held in individual cages with stationary trough feeders and waterers on equal feeding and keeping conditions. Laying hens were fed with compounds feeds of 125 g per day. The results of research: According to the influence of antioxidants lycopene and santoquin, to compare with control group, the average of egg weight during the test period was higher in II group of 3 percentage (p> 0...

Full textAim of master thesis: To analyze the feed, enriched with sunflower, canola and flaxseed oils influence on productivity of laying hens and egg quality. Objectives are: 1. To evaluate a nutritional value of sunflower, rapeseed and flaxseed oils; 2. To analyze influence of compound feed, enriched with sunflower, rapeseed and flaxseed oils, on productivity of laying hens; 3. To analyze influence of compound feed, enriched with sunflower, rapeseed and flaxseed oils, on laying hens egg quality. Methods: A test of feeding was performed on thirty 30 weeks old Lohman Brown cross laying hens which were divided into 3 groups (each of 10 hens). Laying hens of a group I were fed feeds containing 4,5 % sunflower oil, group II – 4,5 % rapeseed oil, group III – 4,5 % flaxseed oil. All diets were isocaloric. During the test laying hens were held in individual cages with stationary trough feeders and waterers on equal feeding and keeping conditions. Laying hens were fed with compounds feeds of 125 g per day. All the eggs were counted and weighted daily including the calculations of egg laying intensity. The following actions were performed every 14 days: identification of individual hen body weight, weighting of feed residue and calculation of feed required for production of 1 kg egg mass. At the end of the test these parameters were investigated: determination of fatty acids, cholesterol and malondialdehyde quantities in the yolk of eggs. Also, egg sensory and texture properties of fresh... [to full text]

Full textThe issue of investigation: To prevent fat from oxidation, synthetic antioxidants are most frequently used. Scientific investigations evidence the prevalence of inorganic selenium. The data on selenium and Vitamin E, using sunflower oil in poultry nutrition, is scarce and controversial. Furthermore, the failure in selecting the antioxidants to preserve oil quality causes oil ant oxidation processes during which free radicals are formed. The latter have negative impact on health of both human beings and animals. Therefore, the aim of the master thesis is to investigate the effect of organic selenium and vitamin E on productivity and eggs quality of layer hens when their nutrition is enriched with sunflower oil. The tasks of the work: 1. To determine the impact of organic selenium and vitamin E on egg laying, usage of feed conversion, livability and physiological condition of layer hens when their nutrition is enriched with sunflower oil. 2. To determine the impact of organic selenium and vitamin E on egg qualitative and quantitative parameters when the hens’ nutrition is enriched with sunflower oil. 3. To determine the impact of organic selenium and vitamin E on egg sensory indices when the hens’ nutrition is enriched with sunflower oil. The most important conclusions: • The hens’ weights in control and trial groups met the rearing recommendations for Lohmann Brown line. • The feed additive of vitamin E – 40mg/kg and 0.5mg/kg of organic selenium increased egg laying intensity...

Full textTheme: ,,The influence of organic selenium and vitamin E for productivity of laying hens when the birdseed is enriched with canola oil”. Research place: Lithuanian University of Health Sciences, Veterinary Academy, Laboratory of Poultry Nutrition’s and Poultry Products by Department of Animal Sciences Purpose of the study: to explore the influence of organic selenium and vitamin E on productivity of laying hens when their food is enriched with canola oil. Goals of the study: 1.To determine the influence of organic selenium and vitamin E on productivity of laying hens, feed consumption, preservation and physiological state of hens when their food is enriched with canola oil. 2. To determine the influence of organic selenium and vitamin E on qualitative and quantitative parameters of eggs when the birdseed is enriched with canola oil. 3. To determine the influence of organic selenium and vitamin E for sensual indicators of eggs when the birdseed is enriched with canola oil. Research methodology: The feeding test was going on for 56 days with 30-week old 20 laying hens of Lohmann Brown line match. The hens were divided into 2 groups, in every group 10 hens. The birdseed of controlled group was enriched with canola oil, non-organic Se and vitamin E. The birdseed of the exploratory group was enriched with canola oil, organic Se and vitamin E. During the test the laying hens have been kept in individual birdcages with water supplies and steady-state feed-troughs under the same... [to full text]

Full textObjectives: This trial were to determinate of effects of antioxidants lycopene and ethoxyquin influence of laying hens production, feed conversion, mortality hens, egg production and egg quality supplement in their feeds sunflower oil. Materials and methods: 30 weeks old Lohman Brown laying hens assigned to three group to one of three diets: control hens were taken commercial feed with sunflower oil, first trial group hens were taken commercial feed + sunflower oil + lycopene (0.5g/kg), second trial (P>0.05). Feeding 125 g per day with granulated mixed feed. Laying hens was keeping in individual cages at like feeding, drinking and keeping condition. The trial consisted 56 day. Results and conclusions of the study: The addition lycopene and ethoxyquin to the feed of laying hens increased eggs production at 4-8% (5-6 eggs from one hen) than hens control group (P>0.05), but feed conversion were increased 4% than hens control group (P>0.05). Cholesterol content in eggs decreased 6% in group with lycopene (P>0.05) and 11% in group with ethoxyquin (P>0.05). Haugh unit increase 2% than it eggs hens control group (P>0.05).
