Papaya Seed

The steady increase in the price of protein feed ingredients and the retraction of antibiotics from diets has encouraged nutritionists to search the alternatives for protein source and functional feedstuffs that can substitute the role of antibiotic growth promoters in poultry production. With crude protein of 24-30%, in vitro protein digestibility of 80% and proportion of essential amino acids of 47%, seed from ripe papaya may be exploited as the alternative protein feed ingredient for poultry. Moreover, the growth promoting effect, antimicrobial and antiparasitic activities, and immunomodulatory and antioxidative activities may confirm the potential of papaya seed as a functional feedstuff that could replace the role of antibiotic growth promoters for poultry. The in-depth study is needed to further elucidate the functionalities of papaya seed on poultry. This review provides the updates on the nutritional contents of papaya seed, the potential of papaya seed as an alternative to conventional protein-rich ingredient, the growth-promoting effect of feeding papaya seed, the antimicrobial and antiparasitic activities of papaya seed, antioxidative activities of papaya seed, and the immunomodulatory activity of papaya seed on poultry.

AbstractNecrotic enteritis (NE) is being considered as one of the most important intestinal diseases in the recent poultry production systems, which causes huge economic losses globally. NE is caused by Clostridium perfringens, a pathogenic bacterium, and normal resident of the intestinal microflora of healthy broiler chickens. Gastrointestinal tract (GIT) of broiler chicken is considered as the most integral part of pathogen’s entrance, their production and disease prevention. Interaction between C. perfringens and other pathogens such as Escherichia coli and Salmonella present in the small intestine may contribute to the development of NE in broiler chickens. The antibiotic therapy was used to treat the NE; however European Union has imposed a strict ban due to the negative implications of drug resistance. Moreover, antibiotic growth promoters cause adverse effects on human health as results of withdrawal of antibiotic residues in the chicken meat. After restriction on use of antibiotics, numerous studies have been carried out to investigate the alternatives to antibiotics for controlling NE. Thus, possible alternatives to prevent NE are bio-therapeutic agents (Probiotics), prebiotics, organic acids and essential oils which help in nutrients digestion, immunity enhancement and overall broiler performance. Recently, probiotics are extensively used alternatives to antibiotics for improving host health status and making them efficient in production. The aim of review is to describe a replacement to antibiotics by using different microbial strains as probiotics such as bacteria and yeasts etc. having bacteriostatic properties which inhibit growth of pathogens and neutralize the toxins by different modes of action.

ABSTRACT Environmental reservoirs of glycopeptide-resistant enterococci (GRE) in Norway have been linked to former growth promoting use of the glycopeptide avoparcin in poultry production. We have examined the prevalence of fecal GRE in poultry and poultry farmers 3 to 8 years after the Norwegian avoparcin ban in 1995 and performed molecular analyses of the GRE population. Fecal samples from poultry farmers and their flocks on 29 previously avoparcin-exposed farms were collected on five occasions during the study period (1998 to 2003). All flocks (100%) were GRE positive in 1998. Throughout the study period, 78.5% of the poultry samples were GRE positive. Glycopeptide-resistant Enterococcus faecium (GREF) was isolated from 27.6% of the farmer samples in 1998 and from 27.8% of the samples collected between 1998 and 2003. The prevalence of fecal GRE in poultry declined significantly during the study period, but prevalence in samples from the farmers did not decline. PCR analysis revealed a specific Tn1546-plasmid junction fragment in 93.9% of E. faecium isolates. A putative postsegregation killing (PSK) system linked to Tn1546 was detected in 97.1% of the isolates examined. Multilocus sequence typing of glycopeptide-susceptible (n = 10) and -resistant (n = 10) E. faecium isolates from humans (n = 10) and poultry (n = 10) on two farms displayed 17 different sequence types. The study confirms the continuing persistence of a widespread common plasmid-mediated vanA-pRE25-PSK element within a heterogeneous GRE population on Norwegian poultry farms 8 years after the avoparcin ban. Moreover, it suggests an important role of PSK systems in the maintenance of antimicrobial resistance determinants in reservoirs without apparent antimicrobial selection.

The aim of this review paper is to explore the available information from research findings on the use of Turmeric (Curcuma longa) as a reliable phytogenic antibiotic for poultry production in the tropics especially in Nigeria and other countries. A wide range of phytogenic additives has found a growing interest in fortification of poultry diets. Supplementation of natural alternatives to antibiotic growth promoters in order to maintain both birds’ performance and health in the tropics will be a welcome development. Turmeric has reportedly been widely supplemented in poultry diets as natural alternative antibiotics in several studies with outstanding performances. The nutritional, medicinal, haematological and phyto-toxicological effects of turmeric were reviewed in this paper. Hence, turmeric supplementation at recommended inclusion rate in poultry feeds without posing any deleterious effects to the birds’ performances as well as the consumers of the products, and ultimately, leading to better profitability on the part of the farmers, will be a nutritional breakthrough for the farmers in the tropics.

In the perspective of the complete ban of antibiotic growth promoters use in animal food by 2006, many alternatives have been studied. However, most of them are not yet technically and/or economically competitive with antibiotics. In this way, the incorporation of bovine colostrum in piglet diets has been studied. Bovine colostrum was chosen for its high concentration in growth promoting and anti-microbial peptides (Playford et al., 2000) and for its high availability. The aims of this study were to measure the efficiency of a bovine colostrum supplementation on growth performances of newly weaned piglets and to evaluate its effects on the digestive and immunological troubles involved by weaning (Pluske et al., 1997 and Vega-Lopez et al., 1995).

The removal of antibiotic growth promoters (AGPs) as feed additives in poultry nutrition from the market in many countries has compelled researchers to find unconventional and safe alternatives to AGPs. Probiotics, prebiotics, enzymes, organic acids, herbs, immune-stimulants and essential oils (EO) have been investigated as feed additives in poultry production. Cinnamon (Cinnamomum zeylanicum), one of the oldest medicinal plants and widely used around the world, can be used in poultry rations in the form of powder or essential oil. Essential oils produced from aromatic plants have become more interesting owing to their potential effects as hypocholesterolaemic agents, antioxidants, antimicrobials, antifungals and stimulants of digestive enzymes. The potential insecticidal and antimicrobial activities of EO against pathogens that cause spoilage in agriculture crops and human diseases might be attributed mainly to the high content of volatile components (mainly cinnamaldehyde, eugenol and carvacrol) in cinnamon oil. The present review focuses on the effects of cinnamon oil as a feed additive on poultry performance, carcass traits, meat quality, hypocholesterolaemic impact, antioxidant activity, immunity and microbiological aspects.

Antibiotics (AGP) have been used as feed additives to promote growth and feed efficiency in poultry production. However, many countries include Indonesia now ban the use of AGP and attempts are made to replace the antibiotic to maintain good performances of broilers. Plant bioactives is one of the alternatives that could replace the AGP. An experiment was conducted in an attempt to replace the AGP in broiler feed with a mixture of some plant bioactives<strong> </strong>(liquid smoke of cashew nutshell, <em>Phyllanthus niruri,</em> and clove leaves). Eight (8) dietary treatments were formulated to have similar nutrients consist of negative control (NC), positive control (NC+AGP), diets supplemented with liquid plant bioactives in 3 levels and diets supplemented with powder plant bioactives in 3 levels.  Each diet was fed to 6 replications of 10 birds each from 1 to 35 days old. The performances and the immune response of the broilers due to the treatments were observed. Results showed that the powder plant bioactives could not improve the performance of broilers. None of the feed additives (AGP or plant bioactives) affect the immune systems of the broilers. However,  liquid plant bioactives in low dose improved the performance of broilers better than the AGP and therefore is suitable to replace the antibiotic as feed additives in broiler diet.

Literature is well-versed with the contribution of financial inclusion from the deposit and financing size and its role in economic growth. These contributions include a boost in economic transactions and efficient resource mobilization. Islamic financial system is different from conventional banking as it distributes the risk equitably and promotes fairness in dealings. It helps in the integration of business gains as a borrower of Islamic capital with the earnings of savers as depositors. This study has proposed two channels via which Islamic financial development may incur growth. First is bank financing penetration, and second is depositor financial inclusion. Based on the data of 41 full-fledged Islamic banks between 2012 and 2017, the results show that both increases in bank and depositor returns have a growth-promoting effect. This prompts the policymakers with new insights. Policymakers should increase Islamic banking penetration to different sectors and regulate for increased extraction of the depositor contribution from the banking financing activity.

The growth-promoting effect of leukotriene D4 (LTD4) has been observed in a variety of cells, including human glomerular epithelial cells. The purpose of this study was to determine the mechanisms underlying this process. LTD4 induction of [3H]thymidine uptake in human glomerular epithelial cells was blocked by the LTD4 receptor antagonist L648,051 when added in a 50-fold excess and by pertussis toxin. Neither drug affected basal DNA synthesis. These results suggest that the LTD4-mediated signal transduction implies activation of a GTP-binding protein that is coupled to a specific receptor. The possible role of protein kinase C (PKC) activation was also studied. In the presence of the PKC inhibitor H-7 or after downregulation of PKC levels by chronic treatment with phorbol ester, stimulation of [3H]thymidine uptake by LTD4 was greatly inhibited. Moreover, treatment of the cells by LTD4 resulted in a time-dependent increase of cytosolic PKC activity, whereas addition of phorbol 12-myristate 13-acetate reduced this activity. Therefore PKC-dependent mechanisms are likely to mediate the growth-promoting effect of LTD4. Finally, three approaches were used to determine the potential role of the Na+-H+ exchanger. First, progressive removal of extracellular Na+ using N-methyl-D-glucamine+ as a substitute inhibited LTD4-induced [3H]thymidine uptake with a 50% inhibitory concentration (IC50) of 85 mM. Second, addition of amiloride reduced the LTD4 growth effect with an IC50 of 6.5 microM, whereas three amiloride analogues exhibited lower IC50 values in accordance with their greater affinity for the Na+-H+ exchanger.(ABSTRACT TRUNCATED AT 250 WORDS)

Potassium diformate (Formi) is odorless, low-corrosive and easy to handle. The European Union (EU) has approved it as non-antibiotic growth promoter, for use in non ruminant feeds. Maximum inclusion level of potassium diformate is 1.8% as registered by the European authorities which can improve weight gain up to 14%. Potassium diformate contains the active ingredients free formic acid as well as formate has the strong anti microbial effect in stomach and also in duodenum. Potassium diformate with its growth promoting and health enhancing effect has proven to be an alternative to antibiotic growth promoters. Its special effect on the micro flora is regarded as the main mode of action. 1.8% potassium diformate in growing pig diets also significantly increase Feed intake and feed conversion ratio was significantly improved where growing pig diets was supplemented with 1.8% potassium diformate. It was also reduced pH in the stomach and duodenum. potassium diformate 0.9% significantly reduced the pH of duodenal digesta. DOI: http://dx.doi.org/10.3329/bjas.v37i2.9887 BJAS 2008; 37(2): 99-105
