Tibia Ash

A 21-day experiment with day-old broilers was conducted in order to assess the effect of phytase supplementation to different cereals-soybean meal based diets on broiler performance and tibia ash. Diets were formulated to contain 4 different cereals (maize, wheat, triticale and barley), 2 levels of dietary calcium (0.6 and 1.0%) and 3 levels of supplemental phytase (0, 500 and 1 000 PU/kg). Supplemented phytase had beneficial effects on broiler performance. It significantly increased body weight gain (P < 0.0003) and feed consumption (P < 0.0361) by 6 and 7% in comparison with the control groups, respectively. No influence on feed conversion ratio and tibia ash was detected. Both body weight gain and feed intake were also significantly influenced by different cereals (P < 0.0001 and 0.0348, respectively). The increasing dietary calcium level resulted in a significant increase in body weight gain (P < 0.0024) and tibia ash (P < 0.0016). Effects of 500 and 1 000 PU/kg were not statistically different between themselves.

Black Soldier Fly (BSF, Hermetia illucens) is an insect species that potentially can be used as a protein source for broiler nutrition. This study aimed to evaluate different inclusion level of BSF on broiler performance and blood metabolites by integrating various data from related studies using meta-analysis. Total of 12 studies that comprised of 31 data points were integrated in the database. Parameters observed included Live Weight (LW), Average Daily Gain (ADG), Daily Feed Intake (DFI), Feed Conversion Ratio (FCR), blood metabolites, and carcass proportion. The database was statistically analyzed by using mixed model method. Different studies were considered as random effects, and the level of BSF was treated as fixed effects. The model statistics used were the p-values and the Akaike information criterion. The significance of an effect was stated when its p-value was < 0.05. The results revealed that BSF feeding had significant linearly reduction effect on LW, ADG, and FCR of broiler (P < 0.05) and significant linearly increase effect on DFI and carcass proportion. However, BSF did not significantly affect on blood metabolites of broilers. It can be concluded that BSF negatively affect the performance of broiler.

SummaryThe efficacy of the probiotic feed additive, Calsporin® (CAL; Bacillus subtilis C-3102), included in broiler diets at 50 mg/kg was evaluated using statistical meta-analysis of data from four different studies conducted using broilers from day-old to market weight at 42 days of age. The body weight, average daily gain, feed intake, feed to gain ratio, mortality and European Production Efficiency Factor (EPEF) data from each experiment were tested for homogeneity between trials before being pooled and analysed in combination to determine whether benefits were consistent independent of trial site and conditions. CAL supplementation significantly improved weight gain (P = 0.0037) between 1 and 21 days of age (3.3%) and feed conversion ratio (P = 0.0492) between 22 and 42 days of age (3.0%). Over the entire experimental period (day 1 to day 42 of age), broilers fed the CAL diets had significantly better (P = 0.0142) feed conversion (2.6%) and higher (P = 0.0062) EPEF (4.6%) compared to the controls. Birds fed diets supplemented with CAL were 1.6% heavier than controls at 42 days of age, a near-significant trend (P = 0.0558). The results demonstrated that CAL in broiler diets, added at an inclusion rate of 50 mg/kg, can be beneficial in terms of broiler performance.
