Meat Quality Parameters of Boschveld Indigenous Chickens as Influenced by Dietary Yellow Mealworm Meal.

ABSTRACT: An experiment was conducted to examine the effects of yellow mealworm larvae (Tenebrio molitor) meal inclusion in diets of indigenous chickens. A total of 160 mixed-sex indigenous Boschveld chickens were randomly divided into four categories: control soybean meal (SBM) and yellow mealworm with percentage levels of 5, 10 and 15 (TM5, TM10 and TM15, respectively). Five replicate pens per treatment were used, with eight birds per pen/replicate. On day 60, two birds from each replicate were slaughtered and eviscerated. Meat quality parameters were measured out on raw carcass and cooked breast meat. The carcass weight, breast weight and gizzard weight of the control group was higher (p < 0.05) than the treatment group (TM15). The cooking loss was lower (p < 0.05) in the SBM control group but higher in the TM15 group. Colour characteristics of breast meat before cooking was lighter in the TM10 and TM15 group, ranged from 61.7 to 69.3 for L* and was significant (p < 0.05). The TM10 and TM15 groups showed a lighter colour than the SBM and TM5 groups. The breast meat pH taken after slaughter was different (p < 0.05) in TM5 and TM15, with the highest reading (pH 6.0) in the TM5 group. In conclusion, our experiment indicated that dietary Tenebrio molitor in growing Boschveld indigenous chickens' diets could be considered a promising protein source for Boschveld indigenous chickens.

Project description:This study aimed to investigate the effects of dietary dihydroartemisinin on the growth performance, meat quality, and antioxidant capacity of broiler chickens. Four-hundred one-day-old Arbor Acres male broilers were randomly assigned to five treatment groups with eight replicates and ten birds each. All broilers were fed a basal diet containing 0, 5, 10, 20 or 40 mg/kg dihydroartemisinin. The results showed that dihydroartemisinin at 10 mg/kg quadratically increased ADG, and dihydroartemisinin at 10 and 20 mg/kg quadratically increased ADFI during the days 1-21 period. Compared to the control group, dihydroartemisinin at 10 and 20 mg/kg quadratically decreased the drip loss at 24 h. Dihydroartemisinin linearly and quadratically decreased the L* value of breast muscles. Dihydroartemisinin at 20-40 mg/kg linearly and quadratically decreased the MDA concentrations at D5 and D 7 of postmortem storage. Dihydroartemisinin linearly and quadratically increased the ABTS scavenging activity at D 7 of postmortem storage. Dietary 20 mg/kg dihydroartemisinin at 21 days and 40 mg/kg dihydroartemisinin at 42 days linearly and quadratically increased serum glutathione concentrations. Dihydroartemisinin at 5-40 mg/kg linearly increased serum total superoxide dismutase activity at 42 days. Dihydroartemisinin at 10-20 mg/kg quadratically decreased serum malondialdehyde contents at 42 days. At 21 days, 20 mg/kg dihydroartemisinin quadratically increased hepatic glutathione concentrations and catalase activities. Compared to the control group, 40 mg/kg dihydroartemisinin linearly and quadratically decreased hepatic malondialdehyde contents. At 42 days, 20 mg/kg dihydroartemisinin quadratically increased catalase activities and reduced the malondialdehyde contents in liver. Dihydroartemisinin quadratically increased the hepatic mRNA expression of Nrf2. Compared to the control group, dihydroartemisinin at 10 and 20 mg/kg quadratically induced the hepatic mRNA expression of HO-1. Dihydroartemisinin at 10-40 mg/kg linearly and quadratically increased the mRNA expression of CAT in liver. These results showed that dihydroartemisinin improved growth performance, meat quality, and antioxidant capacity of broiler chickens, especially at 10 and 20 mg/kg.
