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.

Animal Production Systems

Eutrophication has become a major threat to water quality in the U.S., Europe, and Australasia. In most cases, freshwater eutrophication is accelerated by increased inputs of phosphorus (P), of which agricultural runoff is now a major contributor, due to intensification of crop and animal production systems since the early 1990s'. Once little information is available on the impacts of Brazilian agriculture in water quality, recent changes in crop and animal production systems in Brazil were evaluated in the context of probable implications of the fate of P in agriculture. Between 1993 and 2003, there was 33% increase in the number of housed animals (i.e., beef, dairy cows, swine, and poultry), most in the South Region (i.e., Paraná, Rio Grande do Sul, and Santa Catarina States), where 43 and 49% of Brazil's swine and poultry production is located, respectively. Although grazing-based beef production is the major animal production system in Brazil, it is an extensive system, where manure is deposited over grazed pastures; confined swine and poultry are intensive systems, producing large amounts of manure in small areas, which can be considered a manageable resource. This discussion will focus on swine and poultry farming. Based on average swine (100 kg) and poultry weights (1.3 kg), daily manure production (4.90 and 0.055 kg per swine and poultry animal unit, respectively), and manure P content (40 and 24 g kg-1 for swine and poultry, respectively), an estimated 2.5 million tones of P in swine and poultry manure were produced in 2003. Mostly in the South and Southeast regions of Brazil (62%), which represent only 18% of the country's land area. In the context of crop P requirements, there was 2.6 times more P produced in manure (1.08 million tones) than applied as fertilizer (0.42 million tonnes) in South Brazil in 2003. If it is assumed that fertilizer P use represents P added to meet crop needs and accounts for P sorbed by soil in unavailable forms each year, if swine and poultry manure were to replace fertilizer, there would be an annual P surplus of 0.66 million tonnes in the South region alone. These approximations and estimates highlight that, similarly to other parts of the world, there is a potential for surplus P to quickly accumulate in certain regions of Brazil. Unless measures are developed and implemented to utilize manure P, repeated annual surpluses will create an increasingly difficult problem to solve. These measures can be grouped as source and transport management. Source management attempts to decrease dietary P, use feed additives, manure treatment and composting, as well as careful management of the rate, timing, and method of manure applications. Transport management attempts to control the loss of P in runoff from soil to sensitive waters via use of conservation tillage, buffer or riparian zones, cover crops, and trapping ponds or wetlands. These measures are discussed in the contest of Brazil's climate, topography, and land use, and how successful remediation programs may be implemented at farm and watershed level.

AbstractAntimicrobial resistance (AR) is a worldwide concern. Up to a 160% increase in antibiotic usage in food animals is expected in Latin American countries. The poultry industry is an increasingly important segment of food production and contributor to AR. The objective of this study was to evaluate the prevalence, AR patterns and the characterization of relevant resistance genes in Extended Spectrum β-lactamases (ESBL) and AmpC E. coli from large poultry farms in Ecuador. Sampling was performed from June 2013 to July 2014 in 6 slaughterhouses that slaughter broilers from 115 farms totaling 384 flocks. Each sample of collected caeca was streaked onto TBX agar supplemented with cefotaxime (3 mg/l). In total, 176 isolates were analyzed for antimicrobial resistance patterns by the disk diffusion method and for blaCTX-M, blaTEM, blaCMY, blaSHV, blaKPC, and mcr-1 by PCR and sequencing. ESBL and AmpC E. coli were found in 362 flocks (94.3%) from 112 farms (97.4%). We found that 98.3% of the isolates were multi-resistant to antibiotics. Low resistance was observed for ertapenem and nitrofurantoin. The most prevalent ESBL genes were the blaCTX-M (90.9%) blaCTX-M-65, blaCTX-M-55 and blaCTX-M-3 alleles. Most of the AmpC strains presented the blaCMY-2 gene. Three isolates showed the mcr-1 gene. Poultry production systems represent a hotspot for antimicrobial resistance in Ecuador, possibly mediated by the extensive use of antibiotics. Monitoring this sector in national and regional plans of antimicrobial resistance surveillance should therefore be considered.

The rearing of indigenous chickens is an integral part of the smallholder farming systems in  developing countries, where they are kept by the rural poor to satisfy multiple functions Thus,  the growth performance of Nigerian Fulani ecotype chicken (NFEC) under intensive and  pastured poultry production systems was evaluated. Two hundred, day-old chicks of Nigerian  Fulani ecotype chicken (NFEC) were obtained. The chickens were separated randomly to  intensive and pastured poultry production systems at 12 weeks of age. Data on body weight  ® were taken weekly from day-old to 20 weeks. Data were analyzed using PROC GLM of SAS at statistical significance level of P<0.05. Results showed significant effect of sex of chicken  th th from the 10 to the 20 week of age (P<0.05). Significant interaction effect was observed  between sex and production system at weeks 16 and 18 (P<0.05) when the male chickens  under the intensive production system outpaced their male counterparts in the pastured  poultry. Average daily gain for the period of 20 weeks was 6.83g and 9.21g for female and  male chickens, respectively. Weight gain pattern across weeks was not uniform. There was no  significant difference in the growth rate in the two production systems (P>0.05). The study  revealed that little disparity exists in growth performance of NFEC under the pastured and  deep-litter production systems.

Poultry Nutrition

SummaryIn the context of mismanagement of natural resources going with an increasing consumption of protein from animal origin through the world population, one major challenge for the future in animal nutrition is the improvement of its efficiency and hence sustainability. Up to now, a broad range of methods like feed additives or technological treatments have been available to improve the efficiency or the production of pig-derived and poultry-derived food and hence the sustainability in pig and poultry nutrition. Nevertheless, the exact knowledge of the mode of action of these tools is a prerequisite for their successful application. Furthermore, information concerning their impact on the nutrient availability of the different feedstuffs is of great importance, in order to formulate diets that cover the animals’ requirements. Diets covering the animals’ performance level ovoid undersupplies, which can lead to health problems on the on hand, on the other hand the emissions of nitrogen are kept as low as possible.As a result, the consumption of natural resources like grains can be considerably reduced and the substitution of regional by-products from the feed and food processing industry like wheat bran, dried distillers grains with solubles or rapeseed meal can be dramatically enhanced in diets for monogastric animals, thus contributing to more sustainable livestock production. By improving the efficiency of the production of animal-derived food, the term “sustainable’’ remains highly significant. Increasing efficiency plays an important role in ensuring that the resources required for pig and poultry nutrition are foreseeably available. Currently, there is a combination of different tools like feed additives or technological feed treatments the most promising way of improving sustainability in pig and poultry production systems.
