Different unconventional feed stuffs are used in poultry production to decrease ration cost and the environmental, nutritional and economic benefits derived from the maximal utilization of animal blood. This study was established to assess the effect of feed partially replaced dried blood content supplemented on growth performance responses and carcass. In a feeding trial, 240 commercial broiler chicks a day old, with an average starting weight of 48.40± 1.50 g, Lehmann breed unsexed commercial broiler were randomly allocated to one of four dietary treatments in a completely randomized design. The dietary treatments consisted of the control diet, and three diets which contained varying levels of Sun-dried blood meals SDBM (3, 4 and 5 %) respectively. The experimental diets were formulated to be both isonitrgenous (22.5% CP) and isocaloric (3.10 Mcal /kg). Feed and water were provided adlibitum for a period of 6 weeks. Data for the entire 42 days growth assay indicate the concentration of SDBM in the diet had impact on feed intake. However, birds fed SDBM at 3 or 5% had better weight gains and feed efficiency (p < 0.05) than birds fed 4% SDBM and the SDBM free diet. Carcass yields were similar. Mortality was also unaffected by dietary treatments. In addition, Analysis of productive parameters indicated that dietary SDBM up to 5% had a positive effect on growth performance and that partial replacement of protein sources (blood meal and groundnut cake) with SDBM was possible.

This study was conducted to investigate the effects of dietary supplementation of Endoglucanase producing Bacillus subtilis sp. fermented product (EBFP) on growth performance and meat characteristics in broilers. A total of 480, 1 day old ROSS male broiler chicks were obtained from a local hatchery and randomly allotted to 1 of 4 dietary treatments with 6 replicate pens consisting of 20 chicks. Three additional diets were prepared by mixing 0.1% of commercial cellulase, 0.1%, and 0.2% of EBFP with the control diet and all chicks were fed experimental diets and water ad libitum. Feed intake and body weight (BW) were recorded at 0, 3, and 5 week of the experiment. At the end of the experiment, birds fed a diet containing 0.1% of EBFP had the highest BW compared to birds in other groups (P > 0.01). During 0 to 5 week the experimental period, the dietary addition of 0.1% EBFP significantly increased (P > 0.01) BW gain that was higher than that of birds fed the diet in which only a commercial cellulase was added. No significant difference among treatments was observed in carcass weight, carcass yield, left breast, and thigh meat. These results suggest that dietary addition of cellulolytic probiotics may enhance growth performance compared with the single use of probiotics or enzymes.

The performance of broiler chicks fed on two common species of edible insects: African palm larva (Rhynchophorus phoenicis) and winged termite (Macrotermes bellicosus) in south east, Nigeria were studied using 135 day old Arbor acre birds. Three dietary treatments (T1, T2 and T3) representing Diet A (control: vital feed based fishmeal), Diet B (African palm larvae meal; APLM), and Diet C (containing winged termite meal; WTM), respectively, were used. T1 comprised of a standard feed of brand name ‘vital feed’ containing fishmeal which served as control while T2 and T3 both had insect meal: APLM and WTM, respectively, in place of fishmeal. Forty five broiler chicks were randomly assigned to each of the three dietary treatments at the rate of fifteen chicks per replicate and three replicates per treatment in a completely randomised design. The experiment lasted for eight weeks. During this period, the birds were subjected to similar husbandry and sanitation practices. Weekly record of feed intake, weight gain and linear body measurements were taken. Data obtained were subjected to ANOVA appropriate for completely randomised design and the differences between means were separated using least significant differences. The result showed that chicks fed with control diet based fishmeal (Diet A) had the highest feed intake compared to those fed Diet B and Diet C. Broiler chicks on Diet B however had the highest records in all performance indices (weight gain, feed efficiency ratio, specific growth rate, protein efficiency ratio and linear body measurements) investigated followed by Diet C and lastly Diet A. The study therefore recommends the use of insect meal for complete or partial replacement of fishmeal in poultry feed formulation.

Experiments designed to determine the effects of feeding graded levels of xylanase to 10-kg pigs (exp. 1) and 1-d old broiler chicks (exp. 2) are presented. Pigs received diet composed of corn, rye, wheat, and SBM for 28 d, whereas chickens were fed diet composed of rye, wheat, and SBM for 21 d. Six dietary treatments consisting of a control diet or control plus xylanase (in units kg-1) at 400, 800, 1600, 3200 or 32 000 were fed. Graded levels of xylanase had no effect on growth performance of 10-kg pigs. There were diet and age effects (P < 0.05) on digestibility of DM, CP, and Ca in pigs. Linear and quadratic responses (P < 0.05) in final weight, weight gain, and gain:feed of broiler chicks to graded levels of xylanase were observed in exp. 2. In exp. 2, the effect of xylanase became apparent (P < 0.05) at 800 U kg-1; there were no differences in response to xylanase at 3200 and 32 000 U kg-1. In conclusion, xylanase improved growth performance in 1-d-old broilers fed a diet composed of rye, wheat, and SBM but not in 10-kg pigs that received a diet composed of corn, rye, wheat, and SBM.

Nutritional value of dietary raw bambara nut offal fortified with enzyme (Natuzyme ) on the performance of broiler chickens were investigated. Two hundred and fourty (240), unsexed one day-old commercial broiler chicks (Marshal Strain) were randomly divided into eight groups of 30 birds each. The groups were randomly assigned to eight iso-caloric and iso-nitrogenous diets in a 2 × 4 factorial arrangement involving four levels (0, 10, 20 and 30 %) of raw bambara nut offal and 2 enzyme levels (0 and 0.025 %). Each treatment was replicated three times with ten birds per replicate. There were significant differences (P < 0.05) among treatments in AFW, ADWG, ADFI, FCR and PER. Chickens fed 10 % BGO without ® Natuzyme had higher (P < 0.05) FBW, ADWG and ADFI than chickens fed 0, 20 and 30% BGO diets. Least (P<0.05) ADFI and better FCR was recorded on broiler chickens fed control diet and 20 % BGO with enzyme. respectively. Addition of enzyme improved (P < 0.05) AFW and ADWG at 20 and 30 % BGO level. Significantly (P<0.05) higher AFW, ADWG and ADFI revealed that inclusion level of BGO at 10 % did not pose any deleterious effects on the birds. There were significant (P < 0.05) differences among treatments in the digestibility of dry matter (DM), crude protein, crude fibre (CF), ether extract (EE) and nitrogen-free extract (NFE). There was no interaction (P>0.05) between enzyme and BGO across the dietary treatments. Significant (P < 0.05) differences were observed in all the blood profile parameters observed across the dietary treatments except eiosinophil concentration. It was concluded that up to 30 % BGO can be included in enzyme supplemented broiler finisher diet without adverse effects on the performance, nutrients digestibility and blood profile of broiler finisher chickens

The experiment was conducted to investigate the effects of blood meal supplement on growth performance and hematological parameters changes in broiler chicks. The experiment was carried out with 40 selected homogenous sex and weight broiler chicks having 10 for each group. The lay out of the study was conducted with control group A, fed only with standard commercial broiler ration and other groups viz. B, C, and D were fed with standard commercial ration in addition to 2.5 %, 5.0 %, and 7.5% blood meal supplement with water respectively for 15 days (21st to 35th days of age). The activities of broiler chicks, growth performance, weight loss or gain and any kind of abnormalities were closely observed in every day and the body weight was recorded at 7 days interval. During feeding of blood meal all treated groups were found increased body weight at different level.The blood meal supplied to the broiler chicks increased the growth performance that was directly proportional to the rate of blood meal supplement with water, because the ration was fixed for every group. In hematological observations, TEC, Hb concentration and PCV were decreased but rapid decreasing occurs in group (B) that was statistically significant (P<0.05). In this experiment during feeding of blood meal no clinical symptoms were found markedly. But slight symptoms occur when fed 7.5 % blood meal.The data were analyzed by least significance difference (LSD) with a compute program SPSS-11.50 (Statistical packages for social sciences).

Abstract This study evaluated effects of unpeeled sweet potato meal (USPM) on performance of finisher broiler chickens. A total of 180 one day-old broiler chicks were used for the experiment. Brooding operation was carried out for 2 weeks. Thereafter, the broiler chickens were managed for additional 2 weeks with provision of starter diet and water ad-libitum. At four weeks old, they were equalized for weight and distributed into three dietary treatments (control, 10% and 15% unpeeled sweet potato meal as partial replacement for maize) each replicated four times with 15 birds per replicate; laid out in a completely randomized design. The birds were managed intensively throughout the experimental period until they attained 7 weeks of age. Data collected were subjected to one-way analysis of variance. Results revealed that the inclusion of unpeeled sweet potato meal up to 15% in diets of finisher broiler chickens did not significantly affect the growth performance indices, haematological parameters, carcass traits and most of the serum metabolites except albumin which showed significant variation and ranged from 1.35 g/dl (15% USPM) to 1.90 g/dl (control). Least significant cost (N129.73) per kg feed was recorded in birds fed diet containing 15% USPM relative to highest cost (N136. 63) per kg feed observed in birds fed control diet. Conclusively, incorporation of unpeeled sweet potato meal up to 15% in diet of finisher broiler chickens reduced cost per kg of broiler finisher diet and had no detrimental implications on growth performance, haematological parameters, serum metabolites and carcass traits in chickens.

Abstract The objective of this study was to evaluate the effects of total or partial replacement of animal and fish proteins with a fortified protein blend (PROPLEX MVP) on growth performance of nursery piglets. PROPLEX MVP is a blend of two distinct fermentation biomass streams, refined soybean products, select amino acids, and a NSP enzyme complex. A total of 306 barrows and gilts [(Duroc x (Landrace x Yorkshire), avg. 22 d age and BW 6.37 ± 1.24 kg)] were used in a randomized complete block design with three dietary treatments, each with 19 replicates (pens) of 5 piglets. Dietary treatments were: 1) Control diet (CONT) with animal and fish protein sources (Blood meal, Spray-dried Plasma, and Fish meal); 2) PROPLEX MVP (MVP): CONT with MVP replacing Fish meal; 3) PROPLEX MVP 100 (MVP100): CONT with MVP replacing 100% of animal and fish proteins. Pigs were fed a budgeted amount per head of the assigned experimental diets for the first three feeding phases (Phase 1: 2.3 kg/pig; Phase 2: 4.5 kg/pig; Phase 3: 6.8 kg/pig). A common diet was provided in Phase 4 until day 42 post-weaning. Pigs fed CONT had greater ADG (P &lt; 0.05) compared to MVP100 pigs d 0-7 post-weaning. From d 7 to 14, pigs fed MVP and MVP100 had a significantly greater ADG and G:F (P &lt; 0.05) than pigs fed CONT diet. For the remainder of the experimental period (d 14 to 42), no differences (P &gt; 0.10) were observed among treatments. The use of MVP100 reduced (P &lt; 0.05) the total nursery feed cost by US $1.03/pig and feed cost/kg of weight gain by 12%. In conclusion, MVP protein blend can effectively substitute for animal and fish proteins sources without compromising overall nursery pigs’ growth performance and results in significant feed cost savings.

Intestinal Lesion

Necrotic enteritis (NE) caused by Clostridium perfringens (C. perfringens) results in impaired bird growth performance and increased production costs. Nanotechnology application in the poultry industry to control NE outbreaks is still not completely clarified. Therefore, the efficacy of dietary garlic nano-hydrogel (G-NHG) on broilers growth performance, intestinal integrity, economic returns and its potency to alleviate C. perfringens levels using NE challenge model were addressed. A total of 1200 male broiler chicks (Ross 308) were assigned into six groups; four supplemented with 100, 200, 300 or 400 mg of G-NHG/kg diet and co-challenged with C. perfringens at 21, 22 and 23 d of age and two control groups fed basal diet with or without C. perfringens challenge. Over the total growing period, the 400 mg/kg G-NHG group had the most improved body weight gain and feed conversion efficiency regardless of challenge. Parallel with these results, the mRNA expression of genes encoding digestive enzymes (alpha 2A amylase (AMY2A), pancreatic lipase (PNLIP) and cholecystokinin (CCK)) and intestinal barriers (junctional adhesion molecule-2 (JAM-2), occludin and mucin-2 (Muc-2)) were increased in groups fed G-NHG at higher levels to be nearly similar to those in the unchallenged group. At 14 d post challenge, real-time PCR results revealed that inclusion of G-NHG led to a dose-dependently decrease in the C. perfringens population, thereby decreasing the birds’ intestinal lesion score and mortality rates. Using 400 mg/kg of G-NHG remarkably ameliorated the adverse effects of NE caused by C. perfringens challenge, which contributed to better growth performance of challenged birds with rational economic benefits.

Abstract Mycotoxins may not be an issue every year, but the proper environmental conditions can cause a spike in contaminated grains and cause severe economic impact on pork producers. The objective of this study was to determine the effect of naturally occurring infections of deoxynivalenol, zearalenone and fumonisins (DZF) on growth performance and carcass parameters in grow/finish pigs. One hundred pigs (BW 34.0 ± 0.9 kg; L337 × Camborough, PIC, Hendersonville, TN) were randomly assigned to 1 of 2 dietary treatments with 10 split-sex pens/treatment. The control diet (CTL) contained low levels of DZF and the CTL+DFZ diet contained high levels of DZF. Diets were fed in 4 phases over the 126-d experiment period. The CTL diet contained 1.6, 1.6, 1.8 and 1.2 mg deoxynivalenol/kg and CTL+DZF contained 9.2, 6.9, 5.8 and 3.8 mg deoxynivalenol/kg in the 4 diet phases, respectively. The CTL contained 0.30, 0.32, 0.51 and 0.32 mg zearalenone/kg and 0.7, 0.8, 0.8 and 0.9 mg total fumonisins/kg; CTL+DFZ contained 0.59, 0.72, 0.86 and 0.57 mg zearalenone/kg and 1.0, 1.1, 1.2 and 0.9 mg total fumonisins/kg for phases one through four, respectively. Data were analyzed using PROC MIXED of SAS (9.4) with treatment, sex, and their interaction as fixed effects. Compared to CTL, feeding CTL+DFZ decreased final BW (130.3 vs 120.5 kg; P&lt; 0.001), ADG (0.95 vs 0.79 kg/d; P&lt; 0.001), ADFI (2.73 vs 2.49 kg/d; P=0.016), and G:F (0.35 vs 0.32; P=0.043). Feeding CTL+DFZ decreased HCW (92.3 vs 89.4 kg; P=0.024) and increased dressing percentage (70.9 vs 74.3%; P=0.009) and tended to reduce loin depth (7.0 vs 6.8 cm; P=0.057) compared to CTL. Diet did not affect backfat depth or lean percentage (P &gt;0.10). In conclusion, diets naturally contaminated with multiple mycotoxins reduced growth performance and adversely affected carcass parameters; pigs did not adapt over time to the mycotoxins.

This study was conducted to evaluate the effects of lysine cell mass (LCM) as an alternative lysine source in diets for weaning pigs on growth performance, diarrhea incidence, and blood profiles. In experiment 1, a total of 200 weaning pigs, with an average body weight (BW) of 6.89 ± 1.04 kg, were allotted into one of five treatments with four replicates of 10 pigs per pen in a randomized complete block design (RCBD). The dietary treatments were composed of LCM supplementation (0, 0.25, 0.5, 0.75, or 1.0%) with partial replacement of L-lysine·HCl (0 to 0.8% for phase 1 diets and 0 to 0.07% for phase 2 diets). The BW and feed intake were recorded at the end of each phase (d 0 to 14 for phase 1, d 14 to 35 for phase 2), and diarrhea incidence was checked daily throughout the experimental period. Blood samples were taken from the jugular vein of pigs at 2 weeks and 5 weeks to determine the blood profiles of weaning pigs. In experiment 2, a total of 144 weaning pigs with an average BW of 6.44 ± 1.19 kg were allotted into one of six treatments with six replicates of four pigs per pen in RCBD. The dietary treatments were composed of LCM supplementation (0 to 3.5% for phase 1 diets and 0 to 2.2% for phase 2 diets) with replacement of L-lysine·HCl from 0 to 100%. In experiment 1, partial replacement of L-lysine·HCl with 0 to 1% LCM did not affect growth performance and diarrhea incidence of pigs. An increase in the LCM supplementation from 0 to 1% with partial replacement of L-lysine·HCl had no influence on the blood urea nitrogen concentrations, whereas it resulted in a linear decrease (p < 0.05) in the serum IgG concentrations for 5 weeks. In experiment 2, increasing the dietary level of LCM with replacement of L-lysine·HCl quadratically decreased (p < 0.05) ADG and G–F ratio for phase 2 and G–F ratio for the overall period such that 100% replacement of L-lysine·HCl with LCM decreased ADG and G–F ratio of weaning pigs. An increase in the LCM supplementation with replacement of L-lysine·HCl tended to decrease linearly (p < 0.10) the diarrhea incidence of weaning pigs for the overall period and linearly decrease (p < 0.05) the serum IgG concentrations for 2 weeks. In conclusion, partial replacement of L-lysine·HCl with LCM from 0 to 1% had no negative impacts on the growth performance, but 100% replacement of L-lysine·HCl with LCM decreased the growth performance of weaning pigs. Therefore, LCM could be included in the diets for weaning pigs up to 2.8% and 1.76% for phase 1 and phase 2, respectively, as a substitute for L-lysine·HCl without detrimental effects on the performance of weaning pigs.
