Megjegyzések:The analysis of haematological parameters is of great importance from a diagnostic point of view and is important on a global scale as well. The study aimed to evaluate the effects of the month, farm, bird age, and sex on blood haematology values and to make a reference range for diagnostic purposes for ostriches. Blood samples were taken during the slaughter of the birds in October and November, 2021 and in May and June, 2022. In total, 22 females and 33 males aged between 8 and 60 months from three farms in eastern Hungary were included in the evaluation. Temperature and humidity data were also collected in the indicated months. The month, farm, and age of birds strongly influenced the haematology values. The white blood cell count (WBC) was the highest in June and the mean corpuscular haemoglobin (MCH) was the lowest in May. Farm "B" differed from the two other farms in the mean cell volume (MCV), expressing the lowest mean cell value. For the 8-10- and 15-17-monthold birds, the red blood cell count (RBC), haemoglobin (HGB), and haematocrit (HCT) showed lower values compared to the 11-13- and 48-60-month-old birds. The white blood cell count (WBC), mid-cell count (MID#), and granulocyte count (GRAN#) were the highest for the 8-10- and 11-13-month old age groups; the mean cell volume (MCV) was the highest for the 48-60-month-olds. Differences could not be explained by the weather conditions. Contrary to the literature, birds on farms using probiotics did not always show higher haematological values. To draw more precise conclusions, diagnostic and serum chemical analyses should also be performed in the future.

Cím:Low nitrogen and phosphorus effects on wheat Fe, Zn, phytic acid and phenotypic traits / Brigitta Tóth, Moloi Makoena J., Lóránt Szöke, Labuschagne Maryke
Dátum:2021
ISSN:0038-2353 1996-7489
Megjegyzések:In sub-Saharan Africa, crops are often grown under low nitrogen (N) and low phosphorus (P) conditions, which may impact on the nutritional components of the grains. The aim of this study was to investigate the effect of low N and low P and a combination of the two on iron (Fe), zinc (Zn) and phytic acid content in two commercial South African spring wheat cultivars (PAN3497 and SST806). Phenotypic traits were also investigated. Although cultivar effects were not significant, treatment effects were highly significant for the phenotypic and nutritional traits. Low P stress increased Fe and Zn levels, whereas low N stress had the opposite effect. In addition, low P stress inhibited phytic acid accumulation the most, suggesting that under this treatment, Fe and Zn were more available because of less interaction with phytic acid. Compared to the low N treatment, the low P treatment led to lower reductions in the number of tillers, plant height, stem thickness, number of seeds, weight of seeds and dry weight for both cultivars. While low P had positive effects on the nutritional value of wheat, the combination of low N and P treatment had a negative impact on most of the measured characteristics. Low N conditions had more negative effects on all measured characteristics than low P conditions and was very detrimental to wheat nutritional value and yield.
