Dahlia Tuber Extract and Bacillus subtilis Encapsulation in the Ration of Broiler Chickens: Combined Effects on Blood Fat Profile and Live Weight | Chapter 4 | Research Perspective on Biological Science Vol. 4

 

Background: Antibiotic Growth Promoter (AGP) as a growth promoter has been banned in Indonesia since 2017. This has prompted the search for alternative antibiotics to support poultry products' health, productivity, and safety. This makes probiotics, prebiotics, and synbiotics potential alternatives to replace AGP.

 

Aim of the Study: This study aims to test the effect of adding encapsulated dahlia tuber extract as a prebiotic and Bacillus subtilis as a probiotic on blood lipid profiles and live weight of broiler chicken.

 

Methodology: The research was conducted from October to December 2023, at the Poultry Cage and the Laboratory of Nutrition and Feed Science, Faculty of Animal and Agricultural Sciences, Diponegoro University, Semarang, Indonesia. In this investigation, 200 unsexed Ross strain broilers aged 8 days with an average body weight of 194.53 ± 3.46 g were used. The treatment feed was administered at the age of 8-35 days, containing encapsulated dahlia tuber extract as a prebiotic and Bacillus subtilis as a probiotic (EDTEBs). Dahlia tuber extract and Bacillus subtilis were mixed in a 50:50 ratio. The study used a completely randomised design (CRD) with 4 treatments and 5 replications, each consisting of 10 broilers. The treatment given was T0: basal ration, T1: basal ration + 0.1% EDTEBs, T2: basal ration + 0.2% EDTEBs, T3: basal ration + 0.3% EDTEBs. The parameters measured were blood cholesterol, triglyceride, high-density lipoprotein (HDL), low-density lipoprotein (LDL) levels, and live weight. Data were analysed using the JASP program.

 

Results: The results showed that the addition of dahlia tuber extract encapsulation and Bacillus subtilis encapsulation had a significant effect on cholesterol levels (P < 0.001), triglycerides (P<0.001), HDL (P = 0.002), LDL (P = 0.001), and live weight (P < 0.001) in broilers. The addition of EDTEBs at a concentration of 0.1% yielded optimal results in reducing cholesterol, triglycerides, and LDL levels, while also increasing HDL levels and live weight in broilers.

 

Conclusion: The effectiveness of the combination of Dahlia tuber extract and Bacillus subtilis can be reduced in the digestive tract, as the bioactive compounds and probiotic bacteria may be damaged by acidic gastrointestinal conditions. The addition of encapsulated dahlia tuber extract and Bacillus subtilis at a 0.1% level improved the blood lipid profile of broiler chickens by reducing cholesterol, triglyceride, and LDL levels while increasing HDL levels and live weight. The best results were obtained in the 3% addition treatment.

Exploring the Potential of Moringa oleifera and Andrographis paniculata Leaves as Natural Growth Promoters in Broilers | Chapter 5 | Research Perspective on Biological Science Vol. 5

 

The broiler industry is presently experiencing a significant transformation, prompted by the global demand for antibiotic-free animal products and the prohibition of antimicrobial growth promoters (AGPs). This chapter examines the potential of Moringa oleifera and Andrographis paniculata as natural feed additives to address challenges related to productivity and health in broiler chickens. Recent research indicates that the bioactive compounds in these plants, including flavonoids, polyphenols, and andrographolides, have been demonstrated to enhance gut health and microbial populations. Notably, they reduce Escherichia coli and Salmonella counts while increasing lactic acid bacteria. Phytochemicals also contribute to improved feed efficiency and weight gain. Experimental evidence suggests that supplementation with the nano-liquid extract at a concentration of 0.75% is highly effective in optimizing growth performance, feed conversion ratio, production index, and income over feed cost (IOFC). The incorporation of Moringa oleifera and Andrographis paniculata into broiler nutrition represents a viable, sustainable, and health-conscious alternative to synthetic feed additives, thereby supporting animal welfare and consumer safety.

The First Reference of the Effect of the Syrian Natural Zeolite on Airborne Microorganism Pollution of Broiler Farms | Chapter 5 | Recent Progress in Science and Technology Vol. 8

 The purpose of this study was to investigate the effect of three different levels of Syrian natural zeolite on the bacterial load concentrations in the air of broilers farms for six weeks. The broiler farms are considered as a reservoir of pathogenic microorganism. This research was carried out  in private commercial broiler farm in the Lattakia Governorate, Syria During spring (from March to April) and autumn (from October to November) seasons. In the experiment, commercial broiler hybrid (Roos 308), with a total number (3000), were randomly assigned to four groups. This experiment was created using complete randomization, and each group (750 birds) has three replicates with 250 birds in each replicate (in addition to the control section). The findings revealed that the concentrations value for Staphylococcus spp. during spring, at the sixth week of the fattening period, in the treatment Tz3 (75%) was recorded 7.0×105, while in autumn; the value was 7.4×105 CFU/m3. And for Escherichia coli in spring, was 8.4×103 and in the autumn 8.8×103 CFU/m3. According to the findings, adding Syrian natural zeolite to broiler litter resulted in a significantly (p<0.05) lower concentration of airborne bacteria at the end of the experiment, with a superior effect to Tz3 treatment in the internal air, and the lowest concentration was observed in spring compared to autumn. This result serves as a guide for the optimal use of the various ratios of Syrian natural zeolite, as well as the development of new methods for reducing airborne microorganisms in broiler farms.

Dietary Fat Modulation of Immune Function | Chapter 1 | Emerging Challenges in Agriculture and Food Science Vol. 7

 To increase intakes of these fatty acids, which are currently well below the requirements, there has been considerable interest in enriching poultry meat with long-chain n-3 PUFA. There is some worry, though, that chicken immune and infection resistance may be negatively impacted by diets high in n-3 PUFA.

The goal of this chapter was to examine the impact of dietary fat source and level on the activity of Natural Killer (NK) cells, a marker of immunological function in broiler chickens. Male Cobb 500 broilers that were one day old were fed diets enhanced with fish oil (FO), echium oil, algal biomass, or flaxseed oil at doses of 50, 18, 18, and 19 g/kg, respectively. Twenty birds/treatment had their blood and spleen samples taken at the time of slaughter. The fatty acid content of immunological tissues was significantly influenced by include PUFA in the rations fed to broiler chickens. Investigated was the activity of natural killer (NK) cells. Splenocytes and peripheral blood mononuclear cells (PBMCs) from broilers fed flaxseed oil had the highest levels of NK activity, followed by those from broilers fed algal biomass or echium oil, and those from broilers fed FO had the lowest levels of NK activity. These findings imply that adding n-3 PUFA to chickens without having a major negative impact on their immune system is possible using a DHA-rich algal product. In conclusion, this research added to our understanding of how dietary n-3 PUFA affects the immune system in broiler chickens. Such findings emphasise the need for the poultry business to take into account the health state of poultry when n-3 PUFA, particularly EPA, are added to poultry flesh.

Effect of Feed Restriction on Broiler Chicks Prior to Slaughter: Experimental Investigation | Chapter 12 | Current Topics in Agricultural Sciences Vol. 8

This study's goal was to ascertain the impact of feed limitation on the carcass weight of male broiler chicks between the ages of 32 and 40 days prior to slaughter. 180 Pure line male broiler chicks were chosen at random, given labels, and divided into six groups. When the experimental groups were 32 days old, they began the experimental feeding schedule. Group A received unlimited food for eight days (the control group), whereas groups B and C received 120 and 60 gm/bird/day, respectively. Groups D and E gave each bird 120 or 60 grammes per day for four days, respectively, then went without food for four days. Group F was not given any food during the trial (8 days). The experimental diet was created to be nearly iso caloric-iso nitrogenous and contained sorghum, groundnut cake, broiler concentrate, calcium, salt, lysine, methionine, and premix. Measurements were made for live body weight, feed intake, mortality, carcass and non-carcass data. From 32 to 34 days of age, the final live body weight, carcass weight, and dressing percentage metrics for male broiler chicks were unaffected by the feed restriction programme. However, the meal restriction programme had an impact on net weight (growth or loss) and there was a significant difference (P 0.01) between experimental groups. The ultimate live body weight, net weight (growth or loss), and carcass weight measurements for male broilers subjected to feed restriction were the lowest from 32 to 36 days of age, and the difference was significant (P 0.01). There was no discernible difference in the percentage of experimental groups that were dressed between 32 and 36 days of age (P> 0.05). The feed restriction programme had a substantial impact on all parameters between the ages of 32 and 38 days and 32 and 40 days. It has been determined that the carcass weight of broiler chickens may be controlled using a number of feed limitation tactics, depending on producer circumstances and market demand, with an emphasis on the financial return.
