Effects of Supplementation with Dried Neem Leaf Extract on Lipid Peroxidation and Antioxidant Enzyme mRNA Expression in the Pectoralis Major Muscle of Broiler Chickens.

This study was conducted to evaluate the effects of dietary supplementation of dried neem () leaf extract (DNE) on lipid peroxidation and the expression of genes encoding mRNAs in antioxidant enzymes in the pectoralis major muscle of chickens. A total of 24 male broiler chickens (ROSS308) were divided into three groups (=8) at 21 days of age. The control group of chickens was fed a basal diet, and the remaining two groups of chickens were fed a basal diet supplemented with DNE at a concentration of 0.

Life cycle assessment of animal feeds prepared from liquid food residues: a case study of rice-washing water.

Life cycle assessment (LCA) was used to compare the greenhouse gas (GHG) emissions and energy consumption of three methods used to produce animal feed from concentrated rice-washing water (CRW) and disposing of the rice-washing water through wastewater treatment. Four scenarios were compared using LCA: (i) producing concentrated liquid feed by centrifugation (CC) of CRW with wastewater treatment and discharge of the supernatant, (ii) producing concentrated liquid feed by heating evaporation (HC) of CRW, (iii) producing dehydrated feed by dehydration (DH) of CRW, and (iv) wastewater treatment and discharge of nonconcentrated rice-washing water (WT). The functional unit (FU) was defined as 1 metric ton of rice washed for cooking or processing.

Prophylactic effect of Lactobacillus oral vaccine expressing a Japanese cedar pollen allergen.

Lactic acid bacteria (LAB) represent an attractive delivery vehicle for oral allergy vaccine because of their safety as a food microorganism as well as their potent adjuvant activity triggering anti-allergic immune response. Here, we report the generation of recombinant LAB expressing a major Japanese cedar pollen allergen Cry j 1 (Cry j 1-LAB), and their prophylactic effect in vivo. To facilitate heterologous expression, the codon usage in the Cry j 1 gene was optimized for the host LAB strain Lactobacillus plantarum by the recursive PCR-based exhaustive site-directed mutagenesis.
