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.

An experiment was conducted to determine the influence of an acidifier as an alternative to antibiotics on the performance and gut morphology of broiler chickens. One hundred and eighty (180) 7-day old broiler chicks were randomly assigned to 3 dietary treatments of 4 replicates each. Each replicate had 15 birds. The diets fed to the birds were: Treatment 1- diet with neither antibiotic nor acidifier; Treatment 2- diet with antibiotic and Treatment 3- diet with acidifier. The antibiotic used was Enrofloxacin which was administered to the birds on Treatment 2 via their drinking water while the acidifier used was Biotronic SE (a combination of propionic and formic acids) which was added to the diet of birds on Treatment 3 at the rate of 4kg/tonne of feed. The experiment lasted 42 days. No significant differences were observed in the feed intake, final weight and weight gain of the birds on the different diets. Significant differences were however observed in the villus height in the duodenum and ileum of the birds. The crypt depth values in the different segments of the small intestines of the birds were not significantly affected by the different treatments.Key words: Organic acids, Biotronic SE, Enrofloxacin, Crypt, villus.

A Six week study was carried out to investigate effect of different organic acids (OAs) fed through drinking water on carcass yield and internal organs weight of broiler chickens. The OAs were acetic acid (AA) butyric acid (BA), citric acid (CA) and formic acid (FA). One hundred and fifty (150) day old AborAcre-plus chicks were used. There were five treatments. Treatment 1 which served as control (CON) consumed water with no organic acid, while treatments 2,3, 4 and5 respectively were offered drinking water treated with 0.25% acetic acid (AA), butyric acid (BA), citric acid (CA) and formic acid (FA). Each treatment was replicated three times each having 10 birds arranged in completely randomized design (CRD). Feed and water were offered ad libitum. Results showed that dressed carcass weight and breast weight were improved by all the organic acids. While only AA positively influenced the thigh weight, all the OAs drinking water fed resulted to smaller drumstick compared to the CON. Feeding of AA, BA and FA through drinking water increased (PSO.05) deposition of abdominal fat. Weight of pancreas, small intestine, caecum and large intestine was significantly (P<0.05) higher in CON. The gall bladder was significantly (P<0.05) bigger in all the OA groups. Conclusively, OAs could be fed through the drinking water for improved percentage carcass yield, breast meat and larger gall bladder and invariably bile volume

Leaf Meal

Dietary inclusion of tannin-rich leguminous leaf meals beyond threshold levels can impose toxicity and compromise welfare of pigs. The objective of the study was to determine the response of metabolites, carcass characteristics and internal organs of finishing pigs to Acacia tortilis leaf meal inclusion levels. Thirty Large White × Landrace pigs (61.6 ± 1.23 kg bodyweight) were randomly allotted to six dietary treatments, to give five replicates per treatment. The treatments contained 0, 50, 100, 150, 200 and 250 g/kg of A. tortilis leaf meal and were rendered iso-energetic and iso-nitrogenous. An increase in A. tortilis inclusion was related to an initial increase and then a decrease in feed intake (P < 0.05), weight gain (P < 0.001) and feed conversion ratio (P < 0.05). Serum concentrations of iron and activities of aspartate aminotransferase and alkaline phosphatases increased quadratically (P < 0.001) as A. tortilis leaf meal increased. There was a significant linear increase in alanine aminotransferase activity with leaf meal incremental level. Hepatosomatic index, scaled kidney weight and scaled heart weight increased linearly (P < 0.001) as A. tortilis increased. There was a quadratic increase in the relative weight of lungs (P < 0.001) as leaf meal increased. Although quadratic decreases (P < 0.01) in cold-dressed mass and dressing percentage were observed with incremental levels of A. tortilis leaf meal, there was a linear decrease (P < 0.05) in backfat thickness. It was concluded that serum biochemistry, internal organs and carcass characteristics respond differently to increases in A. tortilis inclusion. The A. tortilis leaf meal can be supplemented in finishing pig diets at low levels before feed efficiency and carcass characteristics are negatively affected.

The influence of feeding with starter diets containing spray-dried bovine colostrum (SBC), spray-dried bovine plasma (SBP), or spray-dried porcine plasma (SPP) on the growth performance and gut morphology of broiler chickens was investigated. The crude protein, lysine, and methionine plus cystine contents (g/kg as received) of SBC, SBP, and SPP were determined to be 766, 736, and 684; 58, 61, and 55; and 27, 28, and 24, respectively. The 3 test proteins were incorporated into a maize–soybean meal diet at a level of 50 g/kg and fed to 6 replicates of 8 male broiler chicks from 1 to 14 days of age. On Day 14, the experimental diets were replaced with a common grower-finisher diet, which was offered until Day 35. Dietary treatments had no effect (P > 0.05) on the weight gain or feed intake of birds during the first 14 days. However, feed/gain of birds fed the SBC diet was lower (P < 0.05) than of those fed the control diet. A trend for a reduction in feed/gain (P = 0.06) was observed in SBP and SPP diets. Dietary treatments had no effect (P > 0.05) on performance during Days 14–35 or Days 1–35. Villus height was increased by 5.7% (P < 0.05) and 4.6% (P = 0.05) in birds fed the SPP and SBP diets, respectively, compared with those fed the control diet. Crypt depth was 6% greater (P < 0.05) in birds fed the SPP diet and tended (P = 0.08) to be greater in birds fed the SBC diet, compared with birds fed the control. The ratio of villus height to crypt depth tended (P = 0.06) to be lower in birds offered the SBC diet compared with the control. Crypt goblet cell density was reduced (P < 0.05) by 13.9% in birds fed the SBC diet, compared with control birds. These results suggest that feeding with diets containing the SBC, SBP, and SPP during 1–14 days of age has some beneficial effects on broiler chickens. Further studies are needed to evaluate these products in less sanitary environments, which may increase the positive responses.

This study aims to examine the effect of Moringa leaf meal on broiler chicken ration to the weight of internal organs, triglyceride levels and HDL. The material used in the study was 60 broiler chicken age 2 weeks strain CP707. The design used Completely Randomized Design (RAL) with five treatments and four replications in each treatment. The five treatments are 100% commercial rations without moringa leaf meal as control and 100% commercial rations with 3%, 6%, 9% and 12% moringa leaf meal. Parameters observed included, liver weight, gizzard weight, meat triglyceride levels, and HDL levels of meat. The data obtained were analyzed by completely randomized design. If among the treatments showed significant differences, then the study will be continued by Duncan's multiple-range test. From the results of this study it can be concluded that the addition of moringa leaf meal at level 10% in the ration is the optimal level to decrease the triglyceride of meat without disturbing the HDL content in the meat and the addition of moringa leaf meal up to 12% in the ration does not give a negative effect on the weight of internal organs.

Gut Morphology

This study was conducted to determine the effect of varying aqueous Moringa oleifera leaf extracts (AMOLE) on the gut morphology and pH of Hubbard broiler chickens. Atotal of 240 Hubbard broiler chickens were randomly allocated into six treatments with four replicates in a completely randomized design. The treatments were positive control (AMOLE ), negative + control (AMOLE), AMOLE60 (60mL of the extracts per litre), AMOLE90 (90mL of the extracts per litre), AMOLE120 (120mL of the extracts per litre) and AMOLE150 (150mL of the extracts per litre). Data on gut morphology weight and length and their pH were measured and analysed by one way analysis of variance. The results showed that dressed, crop, large intestine, kidney and lung weights of birds were influenced (P<0.05) by the treatments. Birds in the control treatments (94.67 %, 94.93 %) had the higher (P<0.05) dressing percentage. Birds on the AMOLE60 had the higher (P<0.05) crop and large intestine weights (4.47 and0.23 %, respectively). The birds on the AMOLE90 treatment had the largest kidney weight of 0.33 %. Absolute crop and caecum length were influenced byaqueous Moringa oleifera leaf extracts while the relative caecum length was the only relative organ length that was influenced by aqueous Moringa oleifera leaf extracts treatment.The pH of the internal organs showed that the gizzards, duodenum, jejunum, ileum, caecum, kidney and lung were influenced (P<0.05) by the treatments. Birds on positive control treatment had higher pH values in most of the parameters measured. Birds on the AMOLE120 had the lowest (P<0.05) duodenum, jejunum and lung pH. This study revealed AMOLE had influence on the gut morphology and pH of broiler chickens. Therefore, it can be concluded that the substitution of antibiotics as a growth promoter with aqueous Moringa oleifera leaf extracts up to 120 ml improved the gut morphology and pH of the intestinal segmentsin broiler chickens. Thus, is recommended that farmers, poultry producers and nutritionists to administer between 60 and 120 mL/litre of AMOLE in the drinking water of broiler chickens to nourish them for good gut morphology and optimum pH of their internal organs.

Abstract. The trial involved 684 Cobb 500 broiler chicks in order to investigate the effects of probiotics and phytogenic additives on performance, gut morphology and cecal microbial concentrations. Birds were assigned to three treatments: control feed, treatment with addition of probiotics in feed and water and treatment with addition of phytogenic blend in feed. The results showed a significant improvement (P<0.01) in body weight gain and a numerical, but non significant (P>0.05) improvement in feed conversion ratio by adding both probiotics and phytogenics in feed. There were no statistically significant differences among treatments regarding total aerobes, anaerobes, lactic acid bacteria, bifidobacteria, enterococci, and Escherichia coli populations (P>0.05) in cecum of broilers. The gut morphology examination showed that probiotics had beneficial effect on jejunum morphology causing a significant (P<0.005) increase in villus height and villus surface area compared to other two groups. On the other hand, phytogenic additive had no effect (P>0.05) on villus height or villus surface area, but reduced the villus/crypt ratio (P<0.05), which may indicate that the improved production results in the group with added phytogenics are not directly connected with changes in gut integrity, but with other physiological mechanisms.

In recent time, there has been call for antibiotics substitute in animal feed due to concerns over its residual effects and the development of antibiotic-resistant bacteria in humans consuming the meat. Short chain fatty acids are often used as viable alternatives to antibiotics. However, there has conflicting reports on the efficacy of the organic acids. This study was therefore aimed at assessing the effects of butyric acid supplemented diets on growth performance, ileal nutrient digestibility, gut morphology and histopathology of broiler chickens in a 21-day feeding trial. Three hundred and thirty-six, one-day old Arbor Acre plus broiler chicks were randomly assigned to seven dietary treatments with six replicate groups of eight chickens each. Diet 1 was the Corn-SBM diet {basal diet (negative control NC)}; Diet 2 (positive control) was basal diet+105g of oxytetracyclene/tonne of feed; Diet 3 comprised NC+0.1% butyric acid); Diet 4 consisted of NC+ 0.2% butyric acid, Diet 5 contained NC+ 0.3% butyric acid, Diet 6 had NC+ 0.4% butyric acid and Diet 7 consisted of NC+ 0.5% butyric acid. Titanium dioxide was added at the rate of 5g/kg as indigestible dietary marker. Performance indices were calculated. On day 21, two chickens per replicate were slaughtered, excised and digesta samples collected at two-thirds to ileo-caeco-colonic junction for digestibility assay. After flushing out the digesta samples, sections of the ileum (5cm posterior to Meckel's diverticulum) were removed for ileal morphological measurements while ileal sections and liver were harvested for histopathological examinations. There were no significant (P>0.05) differences in the performance indices across the treatments. Digestibility of crude protein, ash and nitrogen free extract in broiler chickens fed diets containing antibiotic and 0.2, 0.3, 0.4 and 0.5% butyric acid supplemented diets were significantly (P<0.05) higher than those fed basal diet and diet supplemented with 0.1% butyric acid. Ether extract digestibility of those fed basal diet was similar (P>0.05) to chickens on other dietary treatments. Similar crude fibre digestibility was recorded for basal diet and 0.1% butyric acid supplemented diet. Diets had no significant influence on the villus length, villus height, crypt depth, epithelial thickness and villus height to crypt depth ratio. Histopathological observation of chickens on the control diet showed clinical symptoms of villi and hepatocellular atrophy. No lesions were observed in the ilea of chickens on the antibiotics supplemented diets. Clinical symptoms ranging from villi atrophy, necrosis of the villi, clubbing of the villi, loss of enterocyte, hepatocellular atrophy and necrosis, hyperplasia of bile ductular epithelium, accentuation of sinusoids, and focus of lymphoid aggregate in parenchyma of liver were observed for chickens on butyric acid supplemented diets. Due to the equal level of performance recorded across treatments, it may therefore be concluded that using butyric acid up to 0.5% in diet can replace antibiotic usage but had no comparative beneficial effect on broiler productivity at 21 days.
