“…It is well known that the HMG-CoA reductase inhibitor, Statin, which was extracted from a fungus, inhibits the rate-limiting step in cholesterol synthesis. Previous studies have noticed a significant decrease in plasma cholesterol in broiler chickens fed on diets containing two levels of probiotic (0.8 and 1 g/kg) [ 35 ] and prebiotics and synbiotics [ 36 ].…”

This study was conducted to show the effect of Aspergillus awamori (AA), fructooligosaccharide (FOS), and combined Aspergillus awamori and fructooligosaccharide (AA + FOS) on growth, digestibility, blood parameters, and expression of some growth-related genes. A total of 60 broiler chicks at the age of 15 d were divided into a control group (n = 15) and 3 treatment groups. The control group was fed a basal diet, and the treatment groups were fed basal diets supplemented with 0.05% AA, 0.05% FOS, and combined of 0.05% AA and 0.05% FOS. Results from measurement of growth performance and digestibility revealed a significant increase in the body weight gain with improved feed conversion rate in the experimental groups. Interestingly, dry matter digestibility (DMD) and crude protein utilization (CPU) were improved. In addition, plasma total cholesterol and low density lipoprotein-cholesterol (LDL-C) were decreased, while plasma high density lipoprotein-cholesterol (HDL-C) was increased by feeding AA, FOS, and AA + FOS. Expressions of growth hormone secretagogue receptor (GHSR), insulin-like growth factor 1 (IGF-1), and insulin-like growth factor 1 receptor (IGF1R) were increased in experimental groups. In conclusion, the supplementation of either Aspergillus awamori or fructooligosaccharide or both improves digestibility and growth performance probably by promoting skeletal muscle protein metabolism.

“…The objective of these studies was to evaluate performance of Acid LAC and Kem-Gest acid blends individually, in combination, and in sequence in nursery pig feeding programs as potential alternatives to antibiotic growth promoters. Although antibiotics help ensure a control of diarrhea outbreaks and mortality caused by bacterial infections in pigs, a risk of developing crossresistance of pathogens to antibiotics used in human medicine has become more evident and is of public concern (Piva, 1998;Hillman, 2001). As a result, the swine industry is now searching for an equally competent, if not superior, alternative to antibiotics in relation to growth performance and health in nursery pig diets.…”

Weanling pigs with mean initial BW of 6.04 kg (Exp.1) and 5.65 kg (Exp. 2) and mean age at weaning of 18.2 d (Exp. 1) and 17.7 d (Exp. 2) were used in two 5-wk experiments (Exp. 1, n = 180; Exp. 2, n = 300) to evaluate the effects of an organic acid blend (Acid LAC, Kemin Americas Inc., Des Moines, IA) and an inorganic/organic acid blend (Kem-Gest, Kemin Americas Inc.) on weanling pig growth performance and microbial shedding. In Exp. 1, the 5 dietary treatments were 1) negative control, 2) diet 1 + 55 ppm carbadox, 3) diet 1 + 0.4% Acid LAC, 4) diet 1 + 0.2% Kem-Gest, 5) diet 1 + 0.4% Acid LAC and 0.2% Kem-Gest. In Exp. 2, the 6 dietary treatments were diets 1 through 4 corresponding to Exp. 1, plus 5) sequence 1: 0.4% Acid LAC for 7 d followed by 0.2% Kem-Gest for 28 d, and 6) sequence 2: 0.2% Kem-Gest for 7 d followed by 0.4% Acid LAC for 28 d. Pigs were housed at 6 (Exp. 1) or 10 (Exp. 2) pigs/pen. Treatments were fed throughout the experiment in 3 phases: d 0 to 7, d 7 to 21, and d 21 to 35. In Exp. 1, there were no differences (P > 0.05) in ADG, ADFI, or G:F among the dietary treatments at any time during the study. In Exp. 2, throughout the study, pigs fed carbadox (diet 2) and sequence 1 (diet 5) diets had the greatest ADG (d 0 to 35; 262, 294, 257, 257, 292, and 261 g/d, diets 1 through 6, respectively; P < 0.05), greater ADFI than all other acid treatments (P < 0.05), and tended to have greater ADFI than diet 1 (P < 0.10). Fecal pH, Escherichia coli concentrations, and Salmonella presence were determined at d 6, 20, and 34 for Exp. 1, and on d 32 for Exp. 2. For both experiments, there was no effect of treatment on the presence of fecal Salmonella (P > 0.10) at any sampling time. In Exp. 1, fecal E. coli concentrations for pigs fed the carbadox (P < 0.05) diet were greater than for pigs fed the combination diet with 0.4% Acid LAC and 0.2% Kem-Gest on d 34, and the pigs fed the negative control diet tended (P < 0.10) to have greater fecal E. coli concentrations than those fed the combination diet on d 34. In Exp. 2, fecal pH of pigs fed sequence 1 tended to be greater than fecal pH of pigs fed diet 1, diet 4, or sequence 2 (P < 0.10), but there was no dietary effect on fecal E. coli. In Exp. 1, growth performance of pigs fed the Acid LAC and Kem-Gest diets was similar to each other and to that of the carbadox-fed pigs. Adding the combination of 0.4% Acid LAC and 0.2% Kem-Gest to nursery pig diets reduced ADFI and pig growth rate. In Exp. 2, pigs fed the acid sequence of Acid LAC-Kem-Gest had similar growth performance to pigs fed carbadox, and this novel dietary acid sequence may have merit as a replacement for antibiotics in the nursery phase.

Provision of safe and healthy poultry products to the human being is the prime objective of the poultry industry, but one should keep in mind the welfare of animals and reverence for the environment. Meat and eggs demand also increasing with the increase in world human population. To meet this increasing demand for meat and eggs, antibiotics growth promoters were used world widely. After the ban on antibiotics growth promoters due to its residual effects on human health, nutritionists are focusing on novel growth promoters those without causing productivity loss, or product quality has augmented. Therefore, probiotics are a safe alternative to antibiotics and its beneficial effects proven from many decades. Live microorganisms are used to deliver health benefits to chicken, usually by reestablishing or improving the intestinal microbiota. Probiotics have a beneficial effect on weight gain, immunity, meat traits and somewhat impact on gut health of poultry. The subject of review paper will be worthwhile meant for researchers and poultry nutritionists to advance their understanding of alternatives to antibiotics in poultry production without affecting performance and the welfare of chicken. Contribution/Originality: This study is important in regards to antibiotic resistance in human being coming from animal products. Antibiotic resistance is one of the biggest public health challenges of our time. Each year so many people get an antibiotic-resistant infection, and many people die. Fighting this threat is a public health priority that requires a collaborative global approach across sectors. So, this study will give direction to researchers and food producers to avoid from antibiotics harmful effects to animals and as well as human being. 1. INTRODUCTION Poultry business recognized as one of the rapidly growing section among different agriculture sectors. Consumption of meat and eggs is increasing due to easy availability, comparatively reasonable price and also rich in entire important nutrients which could cover the deficiencies of essential food amino acids, minerals, and vitamins Dhama, et al. [1]; Ajit, et al. [2]. Rinttilä and Apajalahti [3] reported that poultry intestinal health has been investigated and studied extensively for the higher production performance of chicken, as the intestine is an important site where nutrient absorption takes place. While the gut is the main organ which exposed more to pathogens microorganisms after skin [4]. For this purpose, since 1940 antibiotics were used in animal feed as Animal Review
