Health Parameters

This study aimed to investigate the effect of feeding three types of insect meal on broilers’ performance and selected gut health parameters. Day-old straight-run Ross 308 broilers (n=600) were group housed in 24 pens and fed diets containing 10% of either Tenebrio molitor (yellow mealworm, YMW), defatted Hermetia illucens (black soldier fly, BSF) or Alphitobius diaperinus (lesser mealworm, LMW), or a control (CTRL) diet for 35 days. Feed intake and gain were recorded at days 14, 28 and 35. On day 13, four broilers from each pen were placed in metabolic cages to determine apparent total tract digestibility after adaptation to 100% of one of three types of insect meal. Birds were killed, and intestinal content was collected on days 22 and 36 for determination of pH, selected groups of intestinal bacteria and short chain fatty acids (SCFA). Footpad lesions were scored on day 36. Birds fed LMW and YMW ate less than birds fed BSF or CTRL, but feed conversion ratio (FCR) was improved when birds were fed LMW. Dry matter digestibility was similar among insects, but differences were observed in ash and fat digestibility and nitrogen retention in which the BSF meal gave the highest digestibility of these nutrients. Birds fed any type of insect meal diet had higher levels of Clostridium perfringens in caecal and ileal digesta. Footpad dermatitis severity was similar between CTRL and insect-supplemented diets. Total SCFA levels as well as butyrate in digesta of birds fed BSF was lower than the levels of these SCFA in the other treatments. The propionate concentrations in caecal and ileal digesta were high for all diets containing insect meal. In conclusion, gain was maintained when feeding BSF but not LMW and YMW due to lower feed intake. Insect meal did not affect indicators of broilers’ gut health.

Asmara IY, Widjastuti T, Setiawan I, Abun, Partasasmita P. 2018. The growth performances and the gut health parameters of Sentul chickens supplemented with various dosage of turmeric powder. Nusantara Bioscience 10: 121-125. The aim of this study was to investigate the effect of different levels of turmeric powder (0, 1, 2, 3 g/kg) on production performance and the number of Escherichia coli and Staphylococcus aureus bacteria in the intestine of Sentul chickens. The results showed that addition of 3 g/kg of turmeric powder to diet significantly reduced feed intake (FI) and improved feed conversion ratio (FCR) of Sentul Chickens aged 9-16 weeks. The birds fed with control diet had the highest number of S. aureus and E. coli, while the birds fed with the diets added with 2 and 3 g/kg turmeric powder had the lowest number of bacteria. The study reveals that increasing levels of turmeric powder in diets had positive effects on bird’s performance and the number of intestinal bacteria. It can be concluded that a level of 3 g/kg turmeric powder in diets gave the best result due to significantly improved FCR.

Objective: To investigate the effect of antibiotics and/or probiotics on broiler performance, some serum metabolites, cecum microflora composition, and ileum histomorphology under the Egyptian conditions. Design: Randomized controlled experimental study. Animals: Two hundred forty 1-day-old Ross (308) chicks were reared till 35 days of age. Procedures: The birds were randomly allocated into four main groups: a control diet without additives (CON); probiotic (Lactobacillus acidophilus) supplemented diet (PRO); antibiotic (Avilamycin) supplemented diet (ANT) and a mix group (AP) that received antibiotic in the diet form 1 to 4 days of age and treated during the rest of the experimental period with probiotics. Results: Chickens fed on probiotic or antibiotic diets had linear improvement in live body weight (LBW) and feed conversion ratio (FCR) compared with the control group, while the best LBW and FCR were in the AP group. An improvement in the nutrient digestibility was observed in the probiotic added groups (PRO and AP). Serum cholesterol and low-density lipoprotein cholesterol contents decreased when antimicrobial (probiotic or antibiotic) supplementations were used, while there was an increase in high-density lipoprotein cholesterol contents, serum total protein, and albumin levels. Among all groups, cecum Clostridium perfringens and Escherichia coli counts decreased; however, there was an increase in Lactobacillus count compared to the control group. In probiotic supplemented groups (PRO and AP), a significant (P<0.05) improvement in ilea architecture. Conclusion and clinical relevance: Using probiotic after initial treatment with an antibiotic in broiler diets had a positive effect on broiler growth performance, gut health (improved cecum microbial populations and ileum histomorphology), and nutrient digestibility.

Jack Bean

A total of fifty 3-4 weeks old albino rats of the Wistar strain weighing 50-60g were randomly allocated to five dietary treatments in a completely randomized block design to investigate the growth performance and nutrient digestibility of the rats fed diets containing processed dehulled jack bean. Five diets were formulated to contain casein (T1)-control diet, dehulled jack bean soaked in filtrate obtained from raw pap(T2), dehulled jack bean soaked in lye solution (T3), dehulled jack bean boiled for 15minutes (T4) while a protein free diet served as a negative control (T5). The experiment lasted for 28-days.Dehulled jack bean significantly (P>0.05) influenced the growth parameters measured for the Wistar rats. Rats on control diets had the highest value for all the growth indices, feed intake (210.90g), final body weight (103.40g), body weight changes (41.90g), feed conversion ratio (5.10) and protein efficiency ratio (1.41). Rats on T2 (soaked in ‘ogi’ liquor) had feed intake value of (147.40g), followed by rats on T4 (boiled for 15minutes) (117.00g), T5 (negative control) (119.07) and T3 (soaked in lye solution) (79.40g) respectively. Rats on T4 had the highest value for final body weight (67.80g), body weight changes (6.30g), feed conversion ratio (12.27) and protein efficiency ratio (0.25) while rats on T3 had the lowest value for final body weight (67.80g), body weight changes (-32.45g), total feed intake (79.40g) with FCR of (-0.96) for the tested diets. Wistar rats placed on lye treated diet had depressed body weight changes of 59.8% compared to the control. Digestibility studies however showed that rats on control diets had the highest digestibility value of DM and other nutrients, while there was no significant (P<0.05) difference in digestibility value of CF, significant (P>0.05) differences existed in DM, digestibility value of CP, EE and Ash. Rats on T3 and T5 had the lowest digestibility value for Ash (11.48) and CP (37.66). Rats fed dehulled jack bean seed soaked in ogi liquor and boiled for 15minutes showed slight improvement in growth performance and nutrient utilization over those fed lye soaked jack bean. All the processing methods were ineffective when compared to the performance of rat fed casein based diets.

Deficit of conventional feed resources in meeting increased demand has led to hike in their prices culminating in soaring cost of livestock feed. This has necessitated the search for cheap and easily available alternatives. Pride of barbados seed which constitute a waste has potential of becoming a cheap and easily available feed resource. Performance and nutrient digestibility of dietary inclusion of raw pride of barbados seed meal was evaluated in an eight week feeding trial. Atotal of sixteen crossbred (Large White x Landrace) weaned pigs of eight weeks of age were weighed and allotted to four dietary treatments with four pigs each being a replicate in a completely randomized design. Diet 1 (control) was without raw pride of barbados seed meal while 5%, 10% and 15% of virgin raw pride of barbados were included in diets 2,3 and 4 respectively. Weekly weight gain, daily feed intake, feed conversion ratio and nutrient digestibility of raw pride of barbados seed meal was also determined. Results revealed a significant average final body weight of 16.75kg (diet 3) to 24.50kg (diet 4).The pigs fed 15% raw pride of barbados had the highest feed intake of 137.20kg in diet 4 while the lowest feed intake was obtained in pigs fed 10% (diet 3) inclusion level of raw pride of barbados. Pigs maintained on the control diet had the best feed conversion (7.60kg) while the pigs fed diet 3 had the lowest feed conversion ratio (8.93kg). Crude protein, ether extract and dry matter digestibility was highest at T4 (84.15%, 80.21% and 86.70%) respectively while the least values (68.71%, 65.75% and 71.10% was obtained in T2 and T3 respectively. This study concluded that 15% inclusion of raw pride of barbados in the diets of crossbred weaned pigs had no deleterious effect on performance and nutrient digestibility of pigs.

SummaryA total of 432, one-day-old broiler chickens were randomly assigned as a 2 × 4 factorial design (pellet or mash and 0, 25, 50, and 75% whole sorghum levels) in a completely randomised experiment, having six replicates with nine birds per replicate. Body weight and feed intake were measured on a pen basis at 10, 25, and 35 days of age and feed conversion ratio calculated. Pelleting diets significantly improved (P<0.05) feed intake, body weight and carcass yield of broiler chickens at 10 and 24 days of age. Heavier relative gizzard weights with lower pH (P<0.05) were recorded for broiler chickens offered mash diets at 35 days old. Feed conversion ratio at 35 days of age increased (P<0.035, quadratic effect) with higher levels of whole sorghum and levelled off at 75% inclusion rates. Relative gizzard weight at 35 days was marginally increased (P<0.033, linear effect) in line with rising sorghum levels. Similarly, relative bursa and liver weights at 35 days increased (P<0.037, quadratic effect and P<0.033, linear effect, respectively) with sorghum inclusion. The results showed that pelleted diets gave superior performance compared to mash diets. Although higher levels of sorghum inclusion in mash diets enhanced gizzard development, performance parameters of birds at 35 days of age were poorer, with 125 g less body weight and an increase in FCR from 1.51 to 1.62 for the 0% and 75% sorghum levels respectively.

This study was done to determine the impacts Yucca schidigera supplementation to drinking water on the excretion of nitrogen, and subsequently the level of ammonia, intestinal bacterial count, hematological and biochemical parameters, and some performance parameters. A total of 270 one-day old Cobb 500 chicks were equally divided into three groups (90 chicks/group). The first control group (G1) was fed on the basal diets without any yucca supplementation. The 2nd and 3rd groups (G2 and G3) were fed on basal diets with Yucca Plus liquid®, at an 8 h/day supplementation rate of 0.5, and 1 mL/L to drinking water, respectively. The chicks that received yucca showed significant decreases in litter nitrogen content, when compared to controls. The chicks that received liquid yucca had reduced counts of total bacteria (TBC) (p < 0.05), Escherichia coli, and a non-significant increase in the number of lactic acid producing bacteria. They also showed increased activity of antioxidant enzymes, increased levels of immunoglobulins M and G, and decreased levels of lipid peroxidation biomarkers, without a harmful effect on liver and kidney function. The chicks that received yucca showed a better feed conversion ratio. In conclusion, the use of natural additives is necessary to decrease nitrogen losses, feed cost, and environmental pollution; without adverse impacts on animal performance. Liquid supplementation of saponins is valuable for the performance, gut health, and welfare of broiler chickens.

Conjugated linoleic acid (CLA) is formed from linoleic acid (LA; cis-9,cis-12-18 : 2) by intestinal bacteria. Different CLA isomers have different implications for human health. The aim of this study was to investigate LA metabolism and the CLA isomers formed in two individuals (V1 and V2) with different faecal metabolic characteristics, and to compare fatty acid metabolism with the microbial community composition. LA incubated with faecal samples was metabolized at similar rates with both subjects, but the products were different. LA was metabolized extensively to stearic acid (SA; 18 : 0) in V1, with minor accumulation of CLA and more rapid accumulation of vaccenic acid (VA; trans-11-18 : 1). CLA accumulation at 4 h was almost tenfold higher with V2, and little SA was formed. At least 12 different isomers of CLA were produced from LA by the colonic bacteria from the two individuals. The predominant (>75 %) CLA isomer in V1 was rumenic acid (RA; cis-9,trans-11-18 : 2), whereas the concentrations of RA and trans-10,cis-12-18 : 2 were similar with V2. Propionate and butyrate proportions in short-chain fatty acids were higher in V1. A 16S rRNA clone library from V1 contained mainly Bacteroidetes (54 % of clones), whereas Firmicutes (66 % of clones) predominated in V2. Both samples were devoid of bacteria related to Clostridium proteoclasticum, the only gut bacterium known to metabolize VA to SA. Thus, the CLA formed in the intestine of different individuals may differ according to their resident microbiota, with possibly important implications with respect to gut health.

Abstract This experiment evaluated varying levels of Amarula (Sclerocarya birrea A. Rich) nut cake (ANC) on growth performance, nutrient digestibility and carcass characteristics in pigs. Thirty Large White × Landrace (LW × LR) pigs were stratified by weight (average live weight of 20 ± 5 kg) and randomly allocated to the five experimental diets that contained 0 (control), 50, 100, 150 and 200 g ANC/kg DM. Each pig served as a replicate unit, housed individually. Bodyweight, feed intake, average daily gain (ADG) and feed conversion ratio (FCR) were recorded weekly throughout the trial period. On completion of the growth trial, following a 3-day adaptation, a nutrient digestibility study was conducted over 5 days. Thereafter, pigs were fasted for twelve hours, weighed, slaughtered, and carcass samples were collected for analysis. Feed intake was not affected by dietary treatment, but ADGs were reduced at ANC levels > 15%, resulting in poor FCR. Protein digestibility was reduced at ANC levels > 15%, while ether extract and fibre levels increased. Warm and cold carcass weights were lower at ANC levels > 15, with improved meat redness and lightness. It was concluded that ANC could replace SBM in the diet of growing pigs at less than 15% inclusion level.

Aflatoxin B1 (AFB1) is the most dangerous type of aflatoxin that can impair poultry productivity even in low concentrations. The harmful effects of AFB1 should be minimized. The present study was conducted to evaluate the performance, nutrient digestibility, AFB1 residue, and histopathological changes of broilers fed AFB1 diets supplemented with mycosorb. Two hundred-forty 1-day old broiler chicks were allocated randomly to 24 pens (10 birds/pen). The experimental design was a 4 x 2 factorial arrangement, with AFB1 level and yeast glucomannan (mycosorb) supplementation as the main factors.  The treatment diets were control diet; control diet + mycosorb; AFB1 diets (10.36 ppb); AFB1 diets (10.36 ppb) + mycosorb; AFB1 diets (26.97 ppb); AFB1 diets (26.97 ppb) + mycosorb; AFB1 diets (61.06 ppb); AFB1 diets (61.06 ppb) + mycosorb. The results showed that there was no interaction effect was found between the level of AFB1 and mycosorb on the performance and nutrient digestibility. The level of AFB1 did not affect dry matter digestibility coefficient but affected (p<0.05) crude fat digestibility coefficient of broilers. Except for proventriculus, level of AFB1 did not affect bird’s gut size. AFB1 residue was not detected in the broiler tissues fed all diets. Mycosorb alone ameliorated (p<0.05) feed conversion ratio (FCR) of growing birds. The birds fed 61.06 ppb AFB1 diets had darker liver than those fed similar diets added with mycosorb. The addition of mycosorb in AFB1 diets did not heal the hemorrhagic intestines of the birds. In conclusion, feeding low level of AFB1 diets added with mycosorb did not improve the bird’s performance, nutrient digestibility, or gut health. Mycosorb alone improved feed efficiency of the experimental birds.

The objective of the current study is to assess the effects of the inclusion of 6-n phytase to a phosphorous-deficient diet on the growth performance (feed intake, average daily gain, and feed conversion ratio), apparent digestibility of calcium and phosphorus, and bone characteristics of grower–finisher pigs. The experimental diets included a phosphorus-deficient diet containing 0 (negative control), 250, 500, 1000, or 1500 FTU/kg of 6-phytase, and a diet formulated to meet the phosphorus nutrient requirements of pigs (positive control). Pigs were fed the experimental diets from the time they were ~35 kg body weight until they reached slaughter weight of ~110 kg. Bone status of the metacarpal (ash, mineral content) and femur (mineralization, geometry, and mechanical strength) bones were assessed. There was no effect of dietary treatment on feed intake. Feed conversion ratio was improved following inclusion of phytase at a dose of 500 FTU/kg or higher. Phytase inclusion at a dose of 1000 FTU/kg increased the average daily weight gain of grower–finisher pigs. Phytase inclusion at a dose of 500 FTU/kg was sufficient to increase metacarpal phosphorus content. Femur mid-diaphysis ash percentage was significantly increased even after the inclusion of the lowest dose of phytase. Analysis of structural parameters of femur mechanical strength (Young’s modulus, yield stress, yield strain, ultimate stress, ultimate strain) showed that the inclusion of a phytase dose of 500 FTU/kg in growing/finishing diets was sufficient to significantly improve bone status of grower–finisher pigs at slaughter.
