Retence živin u drůbeže při zkrmování diet s podílem moučky z larev potemníka moučného
Kudlová, Lenka
The aim of this diploma thesis is, if the inclusion of 20 and 50 g/kg mealworm meal (TML) in diets for poultry has an effect on nutrient retention, gastrointestinal morphometry and digesta viscosity. Furthermore, a digesta microbiology of laying hens and biochemical blood parameters of broilers were monitored. The collected samples were subjected to laboratory analysis to determine the nutrient retention, gastrointestinal morphometry, digesta viscosity, digesta microbiology and biochemical analysis of blood. The nitrogen retention was not affected by mealworm meal in broilers (p > 0.05). The nitrogen retention was the highest in the control group in laying hens (p < 0.05). A lower width and height and the highest muscle height of the gizzard, but a longer colon, (p < 0.05) were found in control group of laying hens compared to the experimental groups. No differences (p > 0.05) were found in the villi height of the ileum. The digesta viscosity in broilers was not affected by (p > 0.05) experimental diets. The highest value of digesta viscosity in laying hens was found in the group with inclusion 50 g/kg TML (p < 0.05). No differences (p > 0.05) were found in the microbiology of the digesta between the compared groups of laying hens. Significant differences (p < 0.05) in biochemical blood parameters were found in the concentrations of ALT, total bilirubin, urea, creatinine, glucose and α-1 globulin between control and experimental groups of broilers.
