A study was conducted to evaluate the effects of dietary white sorghum (WS), as partial substitute of corn on blood parameters, digestive organ size and intestinal microflora of broilers at 35 d. Cobb 500 broilers (n=400), assigned to 2 groups, were fed with isocaloric and isonitrogenous corn-soybean meal control diets (C) or corn-WS-soybean meal diets (WS), where corn was partially replaced (50%) with WS. At 35 d, sixteen broilers per group were selected for blood sampling, gastrointestinal (GIT) measurements, digesta pH and ileum microflora analysis. There was no effect (P>0.05) of the dietary WS inclusion on blood biochemistry parameters, GIT development and digesta pH of broilers. In our study, dietary WS significantly reduced the ileal population of Enterobacteriaceae (-1.38%; P<0.0001) and E. coli (-1.16%; P=0.020), and increased the Lactobacillus spp. (+1.07%; P=0.014) compared with the C diet. In conclusion, feeding white sorghum, as partial substitute of corn in broiler diets, did not affect blood parameters, digestive organ size and digesta pH, that support the obtained performance. In addition, sorghum had a positive effect of the ileal microflora increasing the beneficial bacterial Lactobacillus spp.

Different Levels

The use of herbs and spices has gained increasing interest as feed additives and possible alternative to antibiotics in poultry production. The effects of using different levels of coriander seed powder or extract on selected blood parameters, intestinal microflora, and immune response of broiler chickens were investigated in this study. A total of 420-day-old broiler chicks were randomly assigned to 7 treatments with 4 replicates and fed for 42 days. Results showed that inclusion of 2.0% coriander powder in broiler diets lowered total cholesterol while blood urea was significantly higher in birds on T4compared to T1and T2. Furthermore, there were no treatment effects onLactobacillusbacteria; however, the population ofE. coliwas significantly higher in the ileum of chickens fed T0. Noticeable significant improvements of antibody titer against Newcastle, infectious bronchitis, and infectious bursal disease were observed in birds receiving coriander extract in water. Immunoglobulin G antibody against sheep red blood cells showed significant improvement in birds fed T3; likewise, immunoglobulin M was significantly higher in birds on T2and T3at 28 d of age. These results revealed that coriander extract or powder can be used as antibiotic alternative in broiler feeds.

Abstract The study evaluated the effects of a Lactobacillus strains probiotic mix on performance, carcass traits, organs size, and intestinal microflora in broilers. A total of 200 one-day-old unsexed broilers were allotted into 2 groups with 5 replicates (20 broilers/replicate). During the feeding trial (35 d) the broilers were fed with a control (basal diet) or probiotic (basal diet plus 3% probiotic mix L. acidophilus and L. plantarum, 1:1 ratio). The probiotic supplementation did not significantly influence the performance, carcass traits and organs size of broilers at slaughter age. No effect of probiotic supplementation on visceral weight or length was observed, except a higher of jejunum (P=0.007) and ileum (P=0.013) weights, and a tendency to higher the caecum length (P=0.070). The probiotic mix had no significant effect on the intestinal pH, but it improved the microflora by decreasing the Enterobacteria and E. coli counts and increasing the Lactobacilli counts and Lactobacilli: E. coli ratio in the ileum and caecum (P<0.05). In conclusion, the probiotic mix (L. acidophilus and L. plantarum mix, 1:1 ratio) did not significantly affect the productive performance but had a positive effect on broilers’ gut microflora.

Residual activity of an Escherichia coli-derived phytase and a commercially available Peniophora lycii phytase along the digestive tract of broiler chicks was compared in order to evaluate their relative resistance to hydrolysis in the digestive tract. Seventy-two 7-d-old male broiler chicks were grouped by weight into six blocks of three cages with four birds per cage. Three corn-soybean meal-based diets were randomly assigned to cages within each block. The three diets were a low P diet containing 3.9 g P kg-1 diet; and low P diet plus either E. coli-derived phytase or the P. lycii phytase at 1000 units kg-1 of feed. The chicks were fed experimental diets from 8 to 22 d of age. At the end of the study, chicks were killed and the contents of the crop, proventriculus and gizzard, jejunum and ileum were collected, freeze-dried, ground and analyzed for phytase activity. Escherichia coli-derived phytase had more residual activity at the proventriculus and gizzard, jejunum and ileum when compared with the P. lycii phytase (P < 0.0001). The E. coli-derived phytase may be more resistant to hydrolysis in the digestive tract when compared with the P. lycii phytase. Key words: Broiler chick, Escherichia coli phytase, residual phytase activity

AbstractThe main aim of the study was to evaluate the effect of two experimental feed additives based on kaolin clay on piglets’ health and microbiota status. The experiment was divided into 2 parts – from birth up to weaning (28 d) and later after weaning up to 70 d of age. Eighteen litters of piglets with sows were divided into 3 groups: control, A and B. The animals from experimental group A were supplemented with kaolin clay (100%), while the animals from group B received kaolin clay enriched with dried pomace of chokeberry and fructooligosaccharides. We noted an improvement in blood parameters related to anaemia, which were significantly better in the experimental group B in comparison to the control and A group (haematocrit; 37.67 and 37.40 vs 39.65%; P<0.0005). The dietary treatments during pre-weaning time influenced the increase of the E. coli strain in the colon and jejunum and had no effect on lowering the population of Salmonella and Shigella in the colon. However, it affected the quantity of Salmonella and Shigella in the jejunum in both A and B (-20%) groups. The rise of commensal bacteria Lactobacillus (+2.3 and +10%) and Bacteroides (+5.82 and +5.11%) was observed in groups A and B in the colon. This effect was not present in the jejunum.

Leaf Meal

Six hundred one-day-old broiler chicks were used to determine the effects of Moringa oleifera leaf meal (MOLM), a probiotic, and an organic acid on growth, weights of digestive organs, and meat quality. Starter, grower, and finisher diets were formulated to which the additives were supplemented, namely T1: 300 g/ton zinc bacitracin and 500 g/ton salinomycin; T2: 1000 g/ton MOLM; T3: probiotic (500 g/ton Enviva Pro); T4: organic acid (1000 g/ton Novyrate C); and T5: without additives. Bodyweight (BW), average daily gain (ADG), and feed intake (FI) were measured weekly through day 28. On days 1 to 7, FI was highest for T4 (22.01 g/d) and lowest for T2 (20.13 g/d). Birds in T3 had the lowest ADG and highest FCR on days 21 to 28, and the highest BW on day 14 and day 21. Twelve birds were randomly selected from each treatment to measure carcass yield, organ sizes and meat quality. pH of the breast muscle was recorded at 45 minutes and 24 hours post mortem. Colour and drip loss were measured 24 hours post mortem. Birds in T4 had the lightest carcasses (1451 g). Birds in T2 had higher redness and chroma values, while hue angle values were highest in T3 birds. The effects of MOLM were comparable with the probiotic and organic acid. That is, they improved growth performance, digestive organ size and meat quality characteristics when included in broiler diets as alternatives to antibiotic growth promoters (AGP).

The consumption of prebiotics is known to affect the balance of gut microbiota. The purpose of this study was to explore how a galactomannan-rich effervescent drink can affect the population of Lactobacillus, Bifidobacterium, E. coli, and the concentration of short-chain fatty acids in the cecum of rats. Twenty-eight male Wistar rats (aged 2 months) were divided equally into 7 groups and treated orally each day for 15 days with 2 mL effervescent drinks with increasing levels of prebiotic galactomannan. The dosage of 500 mg galactomannan increased the growth of Lactobacillus spp. and Bifidobacterium spp. with inhibition of the growth of E.coli with increased formation of short-chain fatty acids such as acetate, propionate, and butyrate in the cecum of rats.

AbstractThe aim of the study was to assess the effect of fermented dried soybean (FSBM) and/or fermented rapeseed meal (FRSM) in diets for weaned piglets on production results, nutrient digestibility, gastrointestinal tract histology, and the composition of the gut microbiota. Piglets in the control group received standard diets with soybean meal. Animals in all experimental groups received diets in which a portion of the soybean meal was replaced: in group FR—8% FRSM; in group FR/FS—6% FRSM and 2% FSBM; in group FS/FR—2% FRSM and 6% FSBM and in group FS—8% FSBM. The use of 8% FRSM or 6% FRSM and 2% FSBM in the piglet diets had a positive effect on average daily gains. Piglets from the FR and FR/FS groups had the highest feed conversion rate. Group FS/FR and FS piglets had significantly lower mortality and lower incidence of diarrhoea. Piglets fed a diet with the fermented components, in particular with 8% FRSM or 6% FRSM and 2% FSBM, exhibited a positive effect on the microbiological composition and histology of intestines, which resulted in improved nutrient digestibility coefficients (ATTD and AID).

AbstractThe broiler industry in the Middle East (ME) faces many challenges related to bacterial infections, including M. gallisepticum, M. synoviae, E. coli, and other gram-negative bacteria, exacerbated by various errors in the brooding process. Antibiotics use in the first three days of life, such as Linco-Spectin 100 SP, tilmicosin, enrofloxacin, tylosin, colistin, and doxycycline, is the trend in the market to control such challenges. This study aimed to evaluate the efficacy of the newly introduced aroA E. coli vaccine (Poulvac E. coli) and its ability to reduce over-reliance on the heavy use of antibiotics in the ME. The study was conducted on 160 broiler chicks, divided into eight even groups. Each group was treated differently in terms of antibiotic therapy and ages at the time of Poulvac E. coli administration and the challenge of virulent avian pathogenic E. coli (APEC), serotype O78. Spray application of Poulvac E. coli at seven days of age plus Linco-Spectin 100 SP during the first three days provided the best results for zero mortality after challenge with APEC, while Poulvac E. coli at seven days with enrofloxacin during the early three days resulted in 10% mortality. Poulvac E. coli hatchery vaccination protected birds against mortality but reduced body weight gain compared to the 7-day group vaccinated with Linco-Spectin 100 SP during the first three days. Poulvac E. coli given on day one or day seven did not affect the immune response to concurrent respiratory viral vaccines and, in some cases, improved response. This study shows that Poulvac E. coli at seven days of age, together with Linco-Spectin 100 during the first three days, has produced the best results in terms of protection and performance in the ME high presence of avian pathogenic E. coli field challenge.
