The aim of the research was to evaluate the influence of sex, breeding group, litter size and age of lambs when placed in lambing pens for their growth rate during rearing. The average daily gain of lambs was evaluated based on their weighing data each week after their placement into lambing pens. Lambs of Improved Valachian, Tsigai and Lacaune breed (n=26) had been gradually integrated to the ...

Black soldier fly larvae (BSFL) are widely used in recycling and upcycling of nutrients agri-food by-products, but low inconsistent BSFL rearing performance (i.e. larval growth, bioconversion rate, substrate reduction) has been identified as a key challenge. The aims this research were two-fold: (1) validate an existing closed system design; (2) assess whether microbial inoculum derived from th...

In this study, we examined the activity of two serine proteases (chymotrypsin and trypsin) and two metalloproteases (carboxypeptidases A and B) during larval development in Anastrepha obliqua fed natural (mango fruit) and artificial (formulation used in mass-rearing) diets. Proteolytic activity of chymotrypsin, trypsin, carboxypeptidase A, and carboxypeptidase B was detected in the midgut of d...
