Like probiotics, postbiotics function without the presence of living cells and are composed of bacteriocins and metabolites that are antibacterial. They improve chicken products and health by reducing acidity in the gut and preventing infectious diseases. A total of 288 one-day-old unsexed broiler birds (Ross308) were divided into sex-specific trea...

Using of antibiotics it has started nearly eighty years ago since 1940 the purpose of using for increasing the immunity against microbes, diseases and to enhance growth in poultry production. The development in bacteria to become resistant against drugs results from using antibiotics for long period it may transformed to humans as well. "Biotic" fe...

Abstract: Modern poultry production looks for feed and water additives that improve the welfare of chickens. The utilization of herbs as additives in feed or drinking water is becoming increasingly well known. The aim of this study was to determine the effect of milk thistle extract (Silybum marianum), administered in drinking water, on chickens’ w...

Recently postbiotics and inulin combinations used as a new feed additives. Within current study, we examined the effect of new feed additives on growth performance and immunoglobulin of broiler. 216 one day-old male chicks were distributed into six treatments, six replicates/six birds in cage system, negative control (NC) without additive, positive...

The mitochondrial cyt b gene plays a serious role in investigating untruthful meat species. This study aimed to authenticate the species of poultry products (Escallop, Nugget, Steak, and Sausage) depending on cyt b gene by using universal cyt b primer. DNA was isolated, and then a band of 359 bp of a mitochondrial cytochrome b gene was produced dur...

Context Broiler meat with excessive of fat and saturated fatty acids content has serious health implication for consumers. The accumulation of abdominal fats in broiler chickens constitutes a loss of dietary energy and also reduces carcass yield. Oil rich in unsaturated fatty acids and l-arginine are effective for reducing fat deposition and improv...

Recently postbiotics used as a new feed additive. In the current study, effect of postbiotic examined on growth performance, intestinal microbiota count and volatile fatty acid of quail. This experiment has been conducted in Qwail field in Qushtapa for six weeks. Two hundred and forty one week old quails were distributed into four treatment groups,...

The research was conducted to assess the impact of supplementation of Saccharomyces cerevisiae (SC) on the quality of products, intestinal microbiota, haematology parameters and histology of local quail. A number of 99 days old quails were randomly assigned and divided into three treatments in triplicate which contained 33 birds in each treatment f...

Larvae meal has been reported as a suitable alternative protein source to fish meal and soybean meal. It contains necessary essential amino acids required in poultry feeding. A feeding trial was conducted to assess the effects of feeding different levels of larvae meal on broiler performance, nutrient digestibility, carcass and meat quality, and ba...

This study examined the effects of different combinations of inulin and postbiotics RG14 on growth performance, cecal microbiota, volatile fatty acids (VFA), and ileal cytokine expression in broiler chickens. Two-hundred-and sixteen, one-day-old chicks were allocated into 6 treatment groups, namely, a basal diet (negative control, NC), basal diet +...

Background Postbiotics (metabolic products by lactic acid bacteria) and prebiotics have been established as substitute to antibiotics in order to enhance immunity and growth performance in broiler chickens. Nonetheless, insufficient information is available on the effects of postbiotics and prebiotics combination on growth performance, faecal micro...

The study investigated the effects of varying dietary calcium (Ca) level and oil sources on the growth performance and carcass quality of broiler chickens. A total of 378, 1-day-old birds (Cobb 500) were fed either 6% palm oil, soybean oil (SO) or linseed oil (LO) in combination with three dietary levels of calcium (1.00%, 1.25% and 1.50%) for 6 we...

This study investigated the efficacy of antibiotics, probiotics and their combination on meat quality of breast muscle in broilers. A total of 480 male one-day-old Cobb chicks were randomly assigned to control (without additive), antibiotic growth promoter (AGP), Bioplus® (probiotics), or AGP + Bioplus® and raised for 42 d. Each treatment was repli...

The study assessed the effects of different types of postbiotics that mixed with different levels of prebiotic (inulin) on carcass, meat and bone quality. A total of 280 male Cobb broiler chickens were randomly assigned to 8 treatment groups. The treatments included basal diet (-ve control), basal diet+neomycin and Oxytetracycline (+ve control), (T...

International Agriculture Congress 2014. November 25th – 27th, 2014, Putrajaya, Malaysia

Background The present study aimed to determine the inhibitory activity of postbiotic produced by L. plantarum using reconstituted media supplemented with different levels of inulin and to select the best combination based on the modified inhibitory activity (MAU/mL) against pathogens. Methods Postbiotics were produced by 6 strains of L. plantarum...
