Canola processing effects on the intestine, blood, and kidney of broiler breeder hens

Efectos del canola procesamiento en intestino, sangre y los riñones de gallinas reproductoras de engorde

Objective. The study was to study the effect of canola processing on the intestine traits, blood metabolites, and kidney enzymes of broiler breeders. Material and methods. Four hundred fifty broiler breeder hens were used for 3 months. The completely randomized design was used with 6 treatments (unprocessed, processed by Lactobacillus Plantarum, Bacillus Subtilis, Aspergillus Oryzae, Neurospora Cytophilla, and Alkalase enzyme) and 5 replications. The collected data were analyzed by the LSmeans procedure of SAS statistical software. Results. The effects of treatments were significant on blood metabolites (p<0.05). Glucose concentration and High-density lipoprotein (HDL) were increased by processing methods. Also, the caecum, jejunum and duodenum weight were influenced(p<0.05). The weight of the duodenum and jejunum was increased and caecum weight was decreased. The processing of canola meal increased the length of the villi and decreased the depth of the crypt of the jejunum (p<0.05). Treatments effect was significant on the Alanine transaminase (ALT) and Alkaline phosphatase (ALP) (p<0.05). The effect of treatments was significant on the digestive amylase, lipase and protease activity (p<0.05). The canola process improved its digestibility. In other words, its protein quality, fatty acid profile and antimicrobial properties were improved. Conclusions. The different processing methods of canola improved the hen’s traits. It can be recommended to use the processed meal instead of the raw canola meal.
