• A total 120 laying hens (60 TETRA BLANCA white egg layers and 60 TETRA SL brown egg layers) were selected from 250 TETRA BLANCA and 250 TETRA SL pullets based on their predicted body fat content by means of computed tomography (CT) at 16 weeks of age. Three groups of pullets were chosen for the investigation with the highest (n = 20), lowest (n =...
1. The aim of this study was to compare the changes in the production and in the body and egg composition of 45 TETRA SL brown egg layers and 45 TETRA BLANCA white egg layers during the first egg-laying period. 2. Changes in the body composition of the hens were followed in vivo by means of computed tomography (CT) four-weekly, between 20 and 72 we...
1. Computed tomography was used for the in vivo determination of yolk ratio in 7000 domestic hen eggs, originated from two markedly different genotypes, in order to examine the effect of egg yolk ratio, gender and genotype on the development of hatched chicks.
2. Eggs with extremely low, average and extremely high yolk ratio were chosen for further...
The large price variation paid for chicken meat originated from organic and conventional systems require up-todate knowledge of physical and sensory properties of the mentioned products. Our aim was to find differences between intensively vs. organically reared chicken breasts as they are currently presented to consumers in Hungary. A total of 30 b...
The aim of this study was to examine, whether the yolk ratio of hen's eggs has an effect on the weight and composition of the liver in chicks at hatching. Altogether 3500 hen's eggs - originated from a 24 weeks old TETRA-H parent stock - were involved in the examination. The yolk ratio of the eggs was determined in vivo by means of computer tomogra...
In the present work, our goal was to match high-resolution computed tomography (CT) scans with cross-sectional anatomical pictures of the turkey (Meleagris gallopavo). Two male BUT 6 (a commercial line) turkeys were used. CT scans with 1 mm slice thickness were performed. The images covered the trunk from the level of the 9th cervical vertebra to t...

1. Using the so-called TOBEC (Total Body Electrical Conductivity) method, which allows the determination of egg composition in vivo, correlations between egg composition, hatchability and hatched chicks' development were studied. 2. A total of 1500 hen eggs (Ross-308) were measured by TOBEC, and eggs with extremely high (10%, n = 150), extremely lo...
Blood serum clinical biochemical parameters of fasted BUT Big 8 male turkeys were determined at the ages of 3 days, 4, 8, 12, 16 and 20 weeks, for a follow-up of the developmental changes of some serum metabolites, enzymes and ions. The serum protein content (total protein, albumin, globulin) increased with age, indicating also the moulting-associa...
The cardiovascular capacity of turkeys is considerably affected by the selection procedure for meat production. To determine the body weight-related changes of some quantitative characteristics of the turkey heart function, serial measurements were carried out. BUT Big 6 turkeys (both sexes) were examined using whole-body magnetic resonance imaging...
Male and female BUT Big 6 and Bronze turkeys (type 1967) kept in a gene reserve were in vivo investigated with non-invasive high resolution computerized tomography by means of a sipral CT scanner. The imaging procedure was carried out at the ages of 5, 12, 16 and 21 weeks on two turkeys, in both sexes. All animals were kept under intensive conditio...
Az anyanyulak termelése jobb, ha fiatal korukban jó a tejellátottságuk, majd korlátozva takarmányozzák őket, illetve, ha a termékenyítés előtt a szoptatási módot megváltoztatják. Az álvemhes nyulak is termelnek tejet. A hústermelést és -minőséget a szopós- és növendékkori tápláltság, ill. az energiakorlátozás egyaránt befolyásolta. A növendéknyulak...

... Amellett, hogy alapvető élelmiszer, funkcionális tulajdonságaiból fakadóan fontos egészségmegőrző szerepet tölt be, s emellett könnyen dúsítható jótékony összetevőkkel. Pozitív tulajdonságai között kell megemlíteni, hogy segíti az agyműködést, a magzati fejlődést, az immunrendszert, csökkenti a daganatos és a kardiovaszkuláris megbetegedések, valamint a korral összefüggő szembetegségek, az érszűkület, és a trombózis kialakulásának és az időskori izomerő-és izomtömeg-csökkenés előfordulásának kockázatát [27,17,52,49,33,41,32,4,19,54]. ...

... Andrássy-Baka et al. (2003a) repeatedly estimated muscle and fat indexes for broilers from 4 to 18 wk of age, and the tool has been validated over the years in the study of Svihus and Katie (1993). In turkeys, Petnehazy et al. (2012) led a study to match high-resolution CT-scan with cross-sectional anatomical pictures of toms, Romvári et al., (2004) investigated heart performance with muscles volume, and Brenøe and Kolstad (2000) and then Andrássy-Baka et al. (2003b) have repeatedly studied fat deposition, muscle, and bone development. CT-scan has also been used to investigate in vivo liver development in goose without anesthetics (Locsmándi et al., 2005). ...
... Part of the lipids synthesized by the liver are transported to the ovary to participate in the formation of egg yolk, and the others are stored in the form of sebum or abdominal fat. For obese individuals with a large amount of fat deposited in the abdominal cavity, fat will compress the ovary and fallopian tube, reducing the function of the reproductive system and affecting the formation of eggs and ovulation rate, resulting in a decline in egg production [6]. Too much or too little fat deposition has a negative effect on the initiation of egg production [7]. ...
... The bone mineral density was given in Hounsfield units (HU) by the scanner software and later converted to g/cm 3 using a phantom (Electron Density Phantom (Model 062 M); Meditest). Total bone was defined in the intervals 200−3000 HU according to Militist et al. (13) . Trabecular and cortical bones were defined in the intervals, respectively, of 200−800 HU and 801−3000 HU, according to Sherlock et al. (14) . ...
... Так, у мясных пород по сравнению с яичными и мясояичными больше масса яйца, его геометрические размеры, масса скорлупы, белка и желтка. Это согласуется с сообщениями о том, что породы птицы обладают специфичными морфологическими признаками яйца (32)(33)(34)(35). При этом ряд авторов указывают, что между массой яйца и его внутренним строением существуют статистически значимые фенотипические и генетические корреляции (36)(37)(38). ...
... Ezekkel a paraméterekkel a fej légtartalmú üregei (orrüreg, orrmelléküregek) jól elkülöníthetők voltak a csontos és lágyszervi képletektől, így bejelölésre kerültek az orrjáratok, a sinusok, üregenként külön színnel Azonban a kötözéssel járó stressz miatt megemelkedett légzésfrekvencia és az esetleges elmozdulásokból eredő műtermékek a felvételeket értékelhetetlenné tehetik, ami a vizsgálatok megismétlésével, az állatok számára nagyobb streszszel és sugárterheléssel járhattak volna. Hivatkozások alapján a pulykában a legtöbb esetben (90%-ban) nem található különálló hátulsó mellkasi légzsák (4,11,12,29,46,48). Az általunk megvizsgált egyedekben ez nem volt minden esetben eldönthető, 4 állat esetében nem lehetett minden kétséget kizáróan elkülöníteni az elülső és a hátulsó mellkasi légzsákokat. ...
... Similarly, in this study, higher duckling weight resulted from higher EW. Milisits et al. (2010) theorized that larger eggs may be advantageous for 2 reasons: 1) they can provide more space for the chick's development; and 2) they can produce chicks with larger nutrient reserves, such as yolk lipid and fatty acids, at hatch. In this study, duckling quality did not differ among HPC and EW groups. ...
... This rapid weight gain is achieved at significant physiological costs. The enormous gain in the mass and relative proportion of tissues is a significant challenge for the cardiovascular system and hemodynamics [4]. It was shown in both broiler chickens and turkeys that the relative cardiac output decreases significantly over a short time of intensive growth [5]. ...
... Augustine et al. (2020) stated that significant variation in SGOT level is reflection of liver problems. Increased levels can also be observed due to high liver metabolism and muscle development taking place during grower phase (Szabo et al. 2005). SGOT level gradually increases with age (Agawane and Lonkar 2004). ...
