In vitro evaluation of enzyme supplementation is used to predict the in vivo response of poultry to enzymes. This study aims to evaluate the efficacy of in vitro techniques in predicting the in vivo response of poultry to enzyme supplementation. Different in vitro techniques such as pepsin, amylase, and protease assays were used to evaluate enzyme efficacy. The results obtained from in vitro techniques were compared with the in vivo response of poultry to the same enzyme supplementation. The study showed that in vitro techniques such as pepsin, amylase, and protease assays can be effectively used to predict the in vivo response of poultry to enzyme supplementation. The study recommends the use of in vitro techniques for predicting the in vivo response of poultry to enzyme supplementation.

The parasitism efficiency of a parasitoid largely depends on its host location and stinging behaviour. This study aimed to assess the stinging behaviour of Diglyphus isaea larvae on some selected host plants. Three host plants, including tomato, eggplant, and pepper, were evaluated for their influence on D. isaea's stinging behaviour. The results showed that the stinging behaviour of D. isaea was significantly influenced by the host plant. The highest frequency of stinging behaviour was observed on tomato plants, followed by eggplant and pepper plants. The study provides insight into the host plant preference of D. isaea, which can be used to optimize its use in biological control programs.

Research exploring greenhouse environment control over the last 50 years has led to significant advancements in understanding the effects of environmental factors on plant growth and productivity. This article provides a comprehensive review of the research conducted over the last 50 years, including the methodology, results, and implications for the future of greenhouse agriculture. The studies involve monitoring and controlling various environmental factors in a greenhouse or growth chamber to create optimal growing conditions for plants. The results indicate that optimal growing conditions vary depending on the plant species and growth stage. Continued research in this area is necessary to address the challenges of climate change and food security and to promote sustainable agriculture.
