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). Keywords: alternative growth promoters, carcass characteristics, digestive organ size, feed conversion

Abstract Introduction: This study examined the effect of dietary Moringa oleifera leaf meal (MoLM) supplementation on intestinal structure vis-à-vis body weight gain in chickens. Materials and Methods: A total of 120-day-old Arbor Acres broiler chicks were randomly assigned to four groups, each with three replicates, 10 birds per replicate. Broiler feed supplemented with different quantities of MoLM, viz.: group T1 (control) - 0%, T2- 7.5%, T3- 15% and T4- 30%, was fed to the birds for 38 days, after which six birds/group were randomly selected and euthanized for histological work. Results: Normal histology was evident in the various intestinal components except the lamina propria and crypts in T4 and villus muscle strands in T3 and T4 where degenerative changes were observed. Villus height, crypt depth, muscle wall thickness and villus area in T1 (controls) were 935.6 pm, 173.8 pm, 192.5 pm and 0.19 mm-2, respectively. Relative to the controls, an increase in the afore mentioned measurements was noted in T2 (6.4%, 8.4%, 10.6% and 10.5%, respectively) while a reduction was recorded in T3 (16.1°%, 10.8°%, 14.8°% and 15.8°%, respectively) and T4 (20.1°%, 14.7°%, 18.3°% and 21.1°%, respectively). Body weight gain within the feeding period increased 31.2, 37.6, 23.9 and 10.9-fold in T1, T2, T3 and T4, respectively. Notably though, feed intake and villus height/ crypt depth ratio were not significantly different (p < 0.05) between dietary treatments. Conclusion: Inclusion of M. oleifera in the diet should be done in moderation as quantities ≥ 15% interfere with intestinal structure and consequently body weight gain.

Nowadays, phytogenic products have received great attention as a growth promoter due to their safety and environmentally friendly effect as a replacement for classical growth promoters such as antibiotics in animal nutrition. Thus, this research seeks the possibility of using fennel seed powder (FSP) as a dietary additive from 19 to 41 days of age on productive performance, carcass traits, meat quality, and production efficiency of broiler chickens raised under thermoneutral and chronic heat stress conditions. Thus, 216 one-day-old Ross-308 broiler chicks were divided into two equal groups. The first group was placed in an independent temperature-controlled room at 23 ± 2 °C. The broiler chicks from the second group were placed in a heat-stressed room and exposed to chronic heat stress conditions (32 ± 2 °C) for seven hours per day from 8 a.m. to 3 p.m. The experimental design was 2 × 3 factorial including two environmental temperatures (thermoneutral vs chronic heat stress) and three experimental diets that contained 0, 1.6, and 3.2% FSP. The chickens were randomly assigned to 18-floor pens per room temperature, representing six replicates per treatment and six birds per replicate. The results showed that dietary fennel seed powder during days 19–41 of age enhanced the growth rate of broiler chickens and improved breast meat redness and reduced temperature under chronic heat stress. In conclusion, 3.2% of fennel seed powder could be used as an agent for enhancing the broiler’s tolerance during chronic heat stress condition from 19 to 41 days of age. Moreover, it is necessary to study in further detail the nitrite and nitrate contents in FSP and their impacts on muscle redness (a*) as well as muscle temperature.

Background: Moringa leaves have wide range of medicinal value including antimicrobial property. Therefore, it could be an alternative of antibiotic growth promoters in poultry but the presence of phytate and other anti-nutrients can reduce the bioavailability of certain nutrients. Enzymes may reduce anti-nutrients effect, break down non-starch polysaccharides (NSPs), reduce intestinal viscosity and ultimately improve digestibility of nutrients by improving gut performance. An experiment was conducted to assess the effect of supplementation of Moringa oleifera leaf meal with multienzyme on the performance, carcass characteristics and economics of broiler chicks. Methods: Day-old, 150 broiler chicks (Vencobb-400) were randomly allotted to five treatment groups. The T1 i.e. control group was fed on basal diet, while, T2, T3, T4 and T5 treatment groups were supplemented with 0.5%, 1.0%, 1.5% and 2.0% of moringa leaf meal in combination with multienzyme @ 50g/100kg feed in the basal broiler starter and finisher ration, respectively.Result: Body weight gain was higher (P less than 0.01) in broilers fed diet supplemented with 1.5% Moringa oleifera leaf meal (MOLM) and multienzyme at 3 or 6 weeks of age. The best feed conversion ratio (FCR) at the starter phase was recorded in the T2 group and over the entire period of the trial T4 treatment group had the best FCR. Significant increase in dressing yield percent and relative weight of giblet was observed in broilers fed diet with 1.5% level of moringa leaf meal and multienzyme. Supplementation of MOLM with multienzyme was profitable in terms of reduction in feed cost per kg gain. It was concluded that supplementation of Moringa oleifera leaf meal @ 1.5% with multienzyme at 50g/100Kg dose in the diet was effective in improving the performance and net profit in broiler chicks.

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.
