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).

Abstract Moringa oleifera (MO) is a widely used as the nutritious and non-traditional feed supplementation containing kinds of bioactive substances. However, the enhancement effect of Moringa oleifera leaf Polysaccharide (MOLP) as a feed additive in broilers growth performance and immunity remains unclear. In this study, MOLP was obtained by water extraction and alcohol precipitation method, then purified with Trichloroacetic acid (TCA) assay. Chickens were randomly divided into 4 groups, to receive different doses of MOLP (0, 0.1, 0.2, 0.4g/kg) in feed for 3 weeks. The body weight gain (BWG) and feed consumption were recorded for feed conversion ratio (FCR) and average daily feed intake (ADFI) calculation. Broiler chickens were sacrificed and sampled on day 14, 21, 28 (D 14, D 21, and D 28) respectively. Serological indicators, including total protein (TP), albumin (ALB), globulin (GLO), and creatinine (CREA) were detected. ELISA kits were applied for detecting the levels of immunoglobulin A (IgA), immunoglobulin G (IgG), interleukin-2 (IL-2), and tumor necrosis factor (TNF-α). From D 21 to D 28, the results showed that middle dose of MOLP significantly increased BWG and ADFI as well as liver and bursa indexes when compared with the control group. In addition, TP and GLO were also increased (P<0.05). All MOLP treatments enhanced the serum concentrations of IgG and IL-2 (P<0.01). Furthermore, results of quantitative RT-PCR showed that high dose of MOLP treatment significantly increased (P<0.001) the mRNA expression levels of IL-2 and TNF-α of chickens relative to the control group. In conclusion, the results showed that MOLP supplementation contributed to improve growth performance and immune response in broiler chickens, and MOLP could be considered as a promising feed additive.

Haematological Indices

This research was conducted to estimate the effects of Persicaria odorata leaf meal (POLM) on haematological indices, serum biochemical attributes, and internal organs parameters, including histomorphological features of the liver, in broiler chickens. A total of 120 one-day-old male broiler chicks (Cobb-500) were randomly allocated into four experimental groups. The dietary treatments were basal diet (BD), which served as the control (C), along with BD + 2 g/kg POLM (Po2), BD + 4 g/kg POLM (Po4), BD + 8 g/kg POLM (Po8), which were the supplemented groups. The body weight gain (BWG) showed a linear increase and feed conversion ratio (FCR) showed a linear decrease with increasing POLM dosage at day 42 (p ˂ 0.05) and for the overall growth performance period (p ˂ 0.01). On day 21 and day 42, the values of red blood cells (RBCs), white blood cells (WBCs), haemoglobin (Hb), and packed cell volume (PCV) showed linear increases (p ˂0.05) as the dosage of POLM increased in the diet. On day 21, dietary supplementation of POLM linearly decreased (p ˂ 0.05) the serum activity of alkaline phosphatase (ALP), aspartate aminotransaminase (AST), alanine aminotransaminase (ALT), and serum levels of urea and creatinine. On the other hand, serum levels of total protein (TP), albumin, and globulin showed a linear increase (p ˂ 0.05) as the POLM dosage increased. On day 42, the serum activity of AST and ALT and serum levels of glucose, cholesterol, triglycerides, urea, and creatinine showed linear decreases (p ˂ 0.05) with increased levels of POLM in the diet. However, POLM supplementation linearly increased (p ˂ 0.05) the serum levels of TP and globulin. Dietary inclusion of POLM did not influence the organ parameters and showed no adverse effects on the liver histomorphology. In conclusion, supplementation of POLM increased the growth performance, improving haematological indices and serum biochemistry profiles of broiler chickens without any deleterious effects on the liver histomorphology. The results of the present study provide evidence that POLM can be safely used at a dose rate of 8 g/kg of feed as an alternative to conventional antimicrobial growth promoters (AGPs).

The objective of this study was to assess the carcass yield, organ weights, and gut morphology response to Vachellia tortilis inclusion in broilers. Unsexed 14-d-old Cobb500™ chicks were randomly assigned to six diets containing 0, 30, 60, 90, 120, and 150 g kg−1 dry matter of V. tortilis leaf meal. The slaughter weight (SW), dressed carcass weight (DCW), breast weight, thigh weight (TW), drumstick weight (DW), and internal organs were measured. Villus height (VH), crypt depth (CD), epithelial, submucosa, and muscularis thickness were taken. The apparent villus surface area (AVSA) and villus to crypt ratio were calculated. There was a linear decrease in SW and DCW (P < 0.05) with the increase of V. tortilis leaf meal. The SW and DCW decreased by 0.77 and 5.25 g for each g kg−1 increase in V. tortilis, respectively. The TW and DW showed no relationship with levels of V. tortilis leaf meal. The relative weight of gizzard, intestine, stomach, heart, and kidney increased linearly (P < 0.05) as levels of V. tortilis increased. The relative weight of the liver was not related to V. tortilis inclusion. The VH, AVSA, VH to CD ratio, as well as submucosa, muscularis, and epithelial thicknesses linearly increased as the V. tortilis inclusion level increased. There was no relationship between V. tortilis leaf meal inclusion and CD (P > 0.05). The increased morphological measurements suggest that leaf meal inclusion alters gut physiology and could influence the digestion and absorption of nutrients in broilers.
