However, the information on their hematology parameters is lacking and hence hampering the poultry industry production of local breeds. The main objective of this study was to examine the hematological parameters of Hungarian Partridge Coloured hen (HPC) and TETRA-SL (TSL) genotype and determine the hematological reference interval values. This trial was part of the larger experiment where a total of 200 chicks (HPC + TSL) were reared. For this trial the blood samples were obtained from brachial wing veins of 8 chicks of each genotype for blood hematological analysis. The results indicated that some of the hematological parameters such as red blood cells-RBC, white blood cells-WBC, hemoglobin-Hb, hematocrit-Ht, platelets-Plt, lymphocytes-LYM, and granulocytes-GRAN were significantly affected by the genotypes (p < 0.05). The genotype did not affect the mean corpuscular volume-MCV, mean corpuscular hemoglobin-MCH, mean corpuscular hemoglobin concentration-MCHC, and GRAN (p > 0.05). The hematological reference interval values were slightly higher in the TSL genotype compared to HPC chicks. It is concluded that genotype has a significant effect on the hematological parameters. The results from this trial will be help and design the baseline reference values for the HPC genotype which will be useful in assessing the health status of these indigenous chickens.Tétel Szabadon hozzáférhető Effects of DL and L-Methionine on Growth Rate, Feather Growth, and Hematological Parameters of Tetra-SL Layers from 1-28 Days of Age(2022) Lugata, James Kachungwa; Oláh, János; Ozsváth, Xénia Erika; Knop, Renáta; Angyal, Eszter; Szabó, CsabaTétel Szabadon hozzáférhető Embryonic Leucine Promotes Early Postnatal Growth via mTOR Signalling in Japanese Quails(2024) Ndunguru, Sawadi Fransisco; Reda, Gebrehaweria Kidane; Csernus, Brigitta; Knop, Renáta; Lugata, James Kachungwa; Szabó, Csaba; Lendvai, Ádám Zoltán; Czeglédi, LeventeTétel Szabadon hozzáférhető Factors Affecting the Ig Content of Sow's Colostrum: A Systematic Review and Meta-Analysis(2025) Szabó, Csaba; Ortega, Arth David Sol Valmoria; Lugata, James Kachungwa; Czeglédi, Levente; Csernus, Brigitta; Gulyás, Gabriella; Kovács, Béla; Pál, Károly; Pusztahelyi, Tünde; Kasza, Rozália; Czakó, Gábor; Horváth, MártaTétel Szabadon hozzáférhető Gut health and influencing factors in pigs(2023) Szabó, Csaba; Lugata, James Kachungwa; Ortega, Arth David Sol ValmoriaTétel Szabadon hozzáférhető Haematological parameters of Hungarian, farmed ostriches(2023) Brassó, Dóra Lili; Komlósi, István; Lugata, James Kachungwa; Rózsáné Várszegi, Zsófia; Massányi, Péter; Knop, RenátaTétel Szabadon hozzáférhető In ovo feeding of methionine affects antioxidant status and growth-related gene expression of TETRA SL and Hungarian indigenous chicks(2024) Lugata, James Kachungwa; Ndunguru, Sawadi Fransisco; Reda, Gebrehaweria Kidane; Gulyás, Gabriella; Knop, Renáta; Oláh, János; Czeglédi, Levente; Szabó, CsabaTétel Szabadon hozzáférhető Individual cage housing affects feed intake and induces sex-specific effects on body weight in Japanese quails(2024) Reda, Gebrehaweria Kidane; Ndunguru, Sawadi Fransisco; Csernus, Brigitta; Lugata, James Kachungwa; Knop, Renáta; Szabó, Csaba; Czeglédi, LeventeTétel Szabadon hozzáférhető Methionine sources and genotype affect embryonic intestinal development, antioxidants, tight junctions, and growth-related gene expression in chickens(2024) Lugata, James Kachungwa; Ndunguru, Sawadi Fransisco; Reda, Gebrehaweria Kidane; Ozsváth, Xénia Erika; Angyal, Eszter; Czeglédi, Levente; Gulyás, Gabriella; Knop, Renáta; Oláh, János; Mészár, Zoltán Mihály; Varga, Rita; Csernus, Brigitta; Szabó, CsabaTétel Szabadon hozzáférhető Physiological responses to DL-methionine and L-methionine supplementation in the early life of TETRA-SL LL hybrid and Hungarian Partridge Colored Hen genotypes(2024) Lugata, James Kachungwa; Szabó, Csaba; Állattenyésztési Tudományok Doktori Iskola; Mezőgazdaság-, Élelmiszertudományi és Környezetgazdálkodási KarMethionine is an essential amino acid crucial in developing feathers and protein synthesis and plays a role in the growth and production performance of poultry. The main objective of the study was to evaluate the physiological responses of newly hatched chicks to in-ovo supplementation of DL-Met and L-Met in TETRA-SL LL hybrid (TSL) and Hungarian partridge colored hen breed (HPC) layer genotypes. Additionally, this study aimed to assess the effects of dietary supplementation with DL-Met and L-Met on the growth performance and hematological parameters of TSL chicks during the starter phase. Two experiments were performed to investigate the effect of DL and L-Methionine at different supplementation levels on the physiological responses, performance, and feather development of layer genotypes. The first experiment examined the impact of in-ovo feeding of methionine sources at 5, 10 and 15 mg/egg on chick development, health status, and hatching performance of the two genotypes. The results indicated that the hatchability ranged from 72% to 100% of 5 mg supplementation; while the in-ovo feeding of higher methionine doses resulted in considerable lower hatchability. However, the in-ovo feeding of DL-methionine significantly improved the hatching weight and ferric-reducing ability of the plasma (FRAP) compared to L-methionine (P < 0.05). Both methionine sources enhanced the chicks' liver health and antioxidant status. Moreover, the in-ovo feeding of either DL-methionine or L-methionine improved intestinal development by increasing the villus width, height, and surface area compared to the control in both genotypes (P < 0.05). The genotype responses to the in-ovo feeding of methionine sources were also noted; the TSL genotype had improved hatching weight, heart weight, hepatic GSH, total antioxidant capacity (TAC), and FRAP than the HPC genotype (P < 0.05). While the HPC genotype had significantly higher muscle GSH and TAC levels, upregulated hepatic IGF1 and IGF1R receptors than the TSL genotype (P < 0.05). The HPC genotype also had overexpressed intestinal IGF1, tricellulin (MD2), OCLN, and superoxide dismutase 1 (SOD1) and GST3 genes than the TSL genotype (P < 0.05). The second experiment used 96-day-old TETRA SL (TSL) chicks and found no significant effect of methionine sources and levels on body weight, average daily gain, and feather development up to 28 days (P > 0.05). However, methionine source and levels had a significant effect on body weight and average daily gain on day 28 (P < 0.05). Furthermore, both methionine sources and levels significantly influenced the hematological parameters, including red blood cells, haemoglobin, white blood cells, lymphocytes, mid-range, and granulocytes values (P < 0.05). The dietary supplementation of DL-methionine at 100% of the recommendation showed favorable results with the highest WBC, RBC, Hb, and Ht values than all treatment groups (P < 0.05). In conclusion, the study highlights the importance of genotype-specific gene expression patterns for enhancing poultry productivity and health. In ovo feeding, L-Met was found to be more effective than DL-Met and was effectively utilized in Hungarian Partridge Colored chicks for muscle GSH, increased intestinal NRF2 gene expression, and decreased plasma uric acid content. On the other hand, DL-Met showed promising potential as a source of in ovo feeding in TETRA SL chicks, improving intestinal development compared to L-Met. Dietary supplementation of DL-Met and L-Met have similar effects on early TSL chicks' development and feather growth but may have different impacts on hematological parameters.Tétel Szabadon hozzáférhető Sex-specific effects of dietary restriction on physiological variables in Japanese quails(2024) Reda, Gebrehaweria Kidane; Ndunguru, Sawadi Fransisco; Csernus, Brigitta; Lugata, James Kachungwa; Knop, Renáta; Szabó, Csaba; Czeglédi, Levente; Lendvai, Ádám ZoltánTétel Szabadon hozzáférhető The Role of Methionine Supplementation on Oxidative Stress and Antioxidant Status of Poultry-A Review(2022) Lugata, James Kachungwa; Ortega, Arth David Sol Valmoria; Szabó, Csaba
