“…Inclusion of organic acids or fermentable growth substrates for lactobacilli in water can reduce the Salmonella and Campylobacter spp. contamination of crops and broiler carcasses (Byrd et al, 2001 (lactic acid); Chaveerach et al, 2004 (acidified drinking water); Hinton et al, 2000b (glucose);2002 (sucrose)). …”

The importance of the crop is often underestimated in poultry production. In addition to storing ingested feed, it also can impact nutrient digestion by digesta softening and the initial activity of feed (endogenous and exogenous) and microbial enzymes. The crop represents the first major defence against poultry pathogens and zoonotic organisms with well established adaptive and innate immune function, and a lactobacilli dominated microbiota capable of reducing the passage of these organisms further along the digestive tract. However, the potential to improve bird productivity and health, as well as affect meat and egg safety, are influenced by the nature of the diet, and in particular feed entry and extended presence in the crop. This is required to promote lactobacilli fermentation, the production of lactic acid and other volatile fatty acids, and the lowering of crop pH. Management practices such as meal feeding and the use of lighting programs with extended dark periods encourage crop utilisation. Further, the use of feed additives such as prebiotics and probiotics may enhance crop function, which in turn contributes to well-being of the entire digestive tract. A healthy and functional crop, along with other segments of digestive tract, has increased importance in an era of reduced antibiotic use in poultry feeds.

“…Among those used on a wider basis, are organic acids, probiotics, and plant extracts (Chaveerach et al 2004). Medicinal plants are one of the possible alternatives that show antimicrobial and growth promoting effect in poultry (Windisch et al 2008).…”

This study was carried out to investigate the effects of dietary supplementation of hydroalcoholic extract of Heracleum Persicum fruit (HPE) on performance, immune responses, small intestine morphology, haematological parameters and carcass characteristics of broiler chickens. A total of 300 day-old Ross 308 broiler chicks were used in a completely randomized design with five treatments and five replicates of 12 chicks each. The treatments were comprised of a corn-soybean meal base diet supplemented with five levels of HPE at 0(control), 100, 200, 300 and 400 mg/kg diet. Average daily feed intake (ADFI) was increased by 100 mg/kg of HPE comparing to control group during 11-24 d (p < 0.05). HPE at the levels of 200, 300 and 400 mg/kg, decreased (p < 0.05) serum cholesterol comparing to control group and showed a linear response to different levels of HPE (p = 0.0007). Also, LDL was decreased by 300 mg/kg of HPE (p < 0.05). The villus height to crypt depth ratio (VH/CD) was increased by 400 mg/kg of HPE, comparing to control group at 42 d (p < 0.05). Also, this ratio showed a linear response to different levels of HPE (p = 0.007). The results of this study indicated that HPE improves performance and intestine morphometrical and haematological parameters of broiler chickens. ARTICLE HISTORY

“…The optimum amount of MOS in bird diets is considered to be 10-20 g/kg diet (Savage and Zakrzewska, 1996). Low-molecular organic acids, such as fumaric or formic acids, also improve the microbiological quality of feeds and reduce the buffering capacity of digesta and the levels of some microorganisms in the feed and caecum of birds (Van der Wielen et al, 2000;Chaveerach et al, 2004).…”

In an experiment performed on 600 ROSS broilers the effect of dietary lactic acid bacteria (LAB), mannan oligosaccharide (MOS) without (LAB, MOS) or with fumaric acid (LAB, MOS, FUA) in comparison with antibiotic-supplemented birds (ANT) on performance, mortality, carcass yield, and microflora spectrum of the digestive tract was studied. The body weight of birds at 42 days was 2.2, 2.5, 2.4 and 2.4 kg, in the CON, ANT, LAB + MOS and LAB + MOS + FUA groups, respectively (P≤0.01). No significant differences between the body weights in the antibioticsupplemented (ANT) and experimental groups were found. Bird mortality in the CON, ANT, LAB+MOS and LAB+MOS+FUA groups was 2.7, 0.0, 0.7 and 0.7%, respectively. Compared with the control group, use of the antibiotic or other additives increased feed intake by 0.49 kg/bird, on average. Dressing percentage averaged 73.5% and was significantly higher in the experimental groups (P≤0.05). The weight of cold carcasses averaged 1.8 kg and was significantly lower in group CON (P≤0.01). The pH of the digestive tract did not differ among groups. LAB and MOS with or without FA increased significantly (P≤0.05) the counts of Streptococcus (P≤0.01) and Lactobacillus in the ileal digesta. The Streptococcus and Escherichia coli counts in the caecal digesta decreased significantly (P≤0.01). No Salmonella, Shigella and Campylobacter were found in the small intestine or caecum of any of the groups.
