“…Death of the birds in each pen was monitored regularly to calculate mortality rate, if any, and a post-mortem examination was conducted to know the cause. At the end of the trial, mortality percentage for each replicate was calculated and used to adjust BW, ADFI and FCR calculations following the method described earlier [ 20 ].…”

Concern for global health security and the environment due to the emergence of antibiotic-resistant bacteria and antibiotic residues in meat and other livestock products has led many countries to restrict the use of antibiotics in animal feed. This experiment was performed to assess the impact of dietary supplementation of a probiotic (Bacillus subtilis) and a postbiotic (Saccharomyces cerevisiae fermentation product) on growth performance, carcass traits, blood haemato-biochemical profile, gut microflora, gut morphology, and immune response in broilers as an alternative to antimicrobials in poultry production system to minimize the effect on global health security. A total of 324 one-day-old Ven Cobb 400 broiler chicks were randomly divided into three dietary groups, each containing 12 replicated pens, and each replicate contained nine chickens. The dietary groups consisted of (1) a basal diet without any growth promoters (T1), (2) the basal diet augmented with Bacillus subtilis at 200 g/MT feed (T2), and (3) the basal diet supplemented with Saccharomyces cerevisiae fermentation product at 1.25 kg/MT feed (T3). To calculate body weight gain, all birds and residual feed were weighed on a replicated basis on days 0, 7, 14, 21, 28, 35, and 42; mortality was recorded daily. At the end of the trial (42 d), two chickens from each replicate were slaughtered for carcass traits, gut microflora, and morphology measurements. Blood samples were collected for the haemato-biochemical profile on 35 d and antibody titer on 28 d and 35 d. Feeding with SCFP (T3 group) significantly improved average daily feed intake (ADFI) and average daily gain (ADG) of chickens compared to the T1 (control) and T2 (probiotic) groups from 1 to 14 days of age. Feed conversion ratio (FCR) was significantly improved in SCFP-fed birds (T3) relative to the control (T1) over the entire experimental period. Carcass traits and blood haemato-biochemical parameters remained unaffected by any diets. However, cholesterol levels and concentrations of corticosterone were significantly lower in T3 compared to T2 and T1 groups. Total E. coli, Enterohaemorrhagic E. coli, ESBL-producing Enterobacteriaceae, and Salmonella counts were significantly lower in T2 and T3 groups compared to T1 group and Salmonella counts were lower in T3 when compared to T2. However, there was no significant difference in Lactobacillus count among treatment groups. A significant increase in villi height and villi-height-to-crypt-depth ratio (VH: CD) was observed in both T3 and T2 groups. On day 28, the T3 and T2 groups exhibited a significant increase in antibody titers against Newcastle disease virus and infectious bursal disease virus. It can be concluded that Saccharomyces cerevisiae fermentation product and Bacillus subtilis probiotic could be viable alternatives to antimicrobials in poultry production considering beneficial impacts in broilers fed an antibiotic-free diet.

“…The DFI was calculated by subtracting the amount of feed (in grams) consumed on the last day from the amount consumed on the first day. The FCR was adjusted for mortality according to Nusairat et al [ 31 ]. The European production efficiency index was also estimated: EPEI = survivability% × average body weight (kg)/market age (day) × FCR (kg feed/kg gain) × 100 [ 32 ].…”

This study aims to evaluate the effectiveness of the dietary addition of Spirulina platensis (SP) and/or garlic powder (GP) on heat-stressed broiler chickens. For this purpose, 600 Ross-308 broiler chicks were allocated at 22 days of age into five groups (G1–G5), each comprising six groups of 20 birds each. Chickens kept in G1 (negative control) were fed a basal diet and raised at 26 ± 1 °C. Chickens kept in G2 to G5 were exposed to periodic heat stress (35 ± 1 °C for 9 h/day) from 22 to 35 days old. Chickens in G2 (positive control) were provided a basal diet, while G3, G4, and G5 were fed a basal diet enriched with SP (1 g/kg diet), GP (200 mg/kg diet), or SP/GP (1 g SP/kg + 200 mg GP/kg diet), respectively. The assessment parameters included the chickens’ performance, malondialdehyde and total antioxidant capacity, blood biochemistry, intestinal morphology, and modulation of lactobacilli and total coliforms in the intestinal microbiota. Our findings demonstrated that supplementing heat-stressed chickens with SP and/or GP significantly mitigated the negative effects on the European production efficiency index (EPEF), survival rate, cholesterol profile, and oxidative stress markers. Chickens supplemented with GP and/or SP exhibited significantly better EPEF and survivability rates. Heat stress had a significant impact on both the gut structure and gut microbiota. However, SP and/or GP supplementation improved the gut morphology, significantly increased the intestinal lactobacilli, and reduced the coliform contents. It was also found that the simultaneous feeding of SP and GP led to even higher recovery levels with improved lipid metabolites, immunity, and oxidative status. Overall, supplementing chickens with SP and/or GP can alleviate the negative effects of heat stress.

“…Broiler memiliki dua periode yaitu starter dan finisher, kebutuhan nutrisi broiler pada kedua periode tersebut berbeda kebutuhannya. Pemeliharaan broiler fase starter membutuhkan pakan dengan kandungan energi 3000-3100 Kcal/kg dengan protein 21-22%, sedangkan untuk fase finisher membutuhkan energi 2900-3000 Kcal/kg dengan protein 20-21% (Nusairat, Odetallah & Wang, 2022). Pemberian pakan yang efisien pada ternak unggas dapat meningkatkan produktivitas ternak dan menekan biaya produksi.…”

Mengkudu fruit contains antioxidant substances to increase endurance, increase appetite, and reduce fat. This study aims to determine the effect of using noni fruit extract (Morinda Citrifolia) to improve broiler performance. The study used a completely randomized design (CRD) with 4 treatments and 4 replicates of 5 birds each. Treatments based on the concentration of mengkudu extract (EM) consisted of P0: control, P1: 10% EM, P2 12.5% EM, and P3: 15% EM. The treatment was given when the DOC was 1 day old until 28 days old. The research parameters were feed consumption, body weight gain, and feed conversion. The results showed that the use of noni extract in drinking water had no effect on broiler performance, body weight gain, and feed conversion. The use of mengkudu extract in drinking water from the level of 10 to 15% decreased feed consumption, increased body weight gain, and decreased broiler feed conversion significantly compared to the control. The addition of mengkudu extract in drinking water up to 15% improved broiler performance.
