The increase in human population, particularly in the developing countries like Nigeria and the demand for animal protein intake has necessitated different approaches of solving protein shortage. A 28-day study was carried out to determine the performance of finishers fed on different hourly soaked doum palm (Hyphaene thebaica) pulp meal (DPPM) diets. Two hundred and sixteen (216) finishers (4 week-old) were randomly allotted to six dietary treatments. Each treatment consisted of 36 birds with three replicates (12 birds per replicate) in a completely randomized design (CRD). Six experimental diets were formulated and designed as follows: T1 (Control) contained 0% DPPM while T2, T3, T4, T5 and T6 contained 12.5% each of 2, 4, 6, 8 and 10 hours soaked DPPM as substitute for maize, respectively. Feeds and water were provided ad libitum for all treatment groups. The average body weight gain (40.44- 42.71 g/b/d), average feed intake (87.52-96.73 g/b/d) and feed conversion ratio (2.14-2.34) were non-significant (p>0.05) regardless of the dietary treatments. Statistical differences (p<0.05) were observed in some carcass parameters such as thigh (13.40-14.98%), neck (5.32-6.55%), shank (3.81-5.2 %), wing (9.80-11.41%), head (2.43-3.74%) and two haematological indices; white blood cell (160.67-189.53 X 103/mm3) and eosinophils (0.33-2.00%) across the treatment groups. The processed DPPM could serve as a rich energy source in broiler feeds with the raw doum palm pulp containing 2987.45 kcal/kg. Also, soaking the pulp for 2 to 10 hours before been included in broiler diet improved the nutritional content, acceptability, palatability and utilization of the feed by the broilers. Thus, up to 12.5% processed DPPM can be included in the diets of broiler chickens without adverse effect on growth performance, nutrient digestibility, carcass characteristics and haematological indices of chickens.

Background: Copper (Cu) is an essential trace mineral for growth, production and health of poultry. Due to its poor absorption from inorganic source which is common supplemental form, large amount of Cu is excreted in the excreta. This experiment was conducted to assess the bioavailability of Cu from organic and nano sources at lower level of supplementation to reduce the excretion level without compromising the growth performance of chicken. Methods: A total of 420-day-old Giriraja chicks were randomly assigned to 7 treatment groups having 4 replicates each (15 chicks per replicate). The basal diets of both chick (0-6 weeks) and grower phases (7-10 weeks) were supplemented with 20 and 30 ppm of Cu from inorganic source as control (T1), the groups T2, T3 and T4 supplemented with 100, 75 and 50% of control from organic Cu, T5, T6 and T7 treatment diets supplemented with 75, 50 and 25% of control from Cu nanoparticles, respectively. Result: The grower phase and cumulative body weight gain was significantly (p less than 0.05) higher in T2 compared to T1, T6 and T7 groups, while the feed intake in chick phase was lower in T2, T5 and T7 groups as compared to T1, T3, T4 and T6. The chick phase feed conversion ratio was significantly (p less than 0.05) better in T2 and T5 groups compared to T1, T3, T4, T6 and T7, whereas the cumulative FCR was better in T2 and T5 compared to T6 and T7 groups, while it was not affected during grower phase. The dry matter and crude protein metabolizability were significantly (p less than 0.05) higher in T2 and T5, the organic matter and ether extract metabolizability was higher only in T5. The crude fiber and nitrogen free extract was not affected by the treatment diets. Nitrogen excretion was significantly (p less than 0.05) lower and its retention was higher in T2 and T5 treatment groups but was comparable with control. The Cu excretion through excreta was significantly (p less than 0.05) higher and its retention was lower in control as compared to all dietary treatments. Hence, it was concluded that the Cu supplementation from organic or nanoparticles form can be reduced by 50 and 75% of standard, respectively without compromising the growth performance of birds and nutrient digestibility of diets.

We investigated the effects of a blend of organic acids (OAs) and medium-chain fatty acids (MCFAs) supplementation in 800 1-d-old male Ross 308 broiler chickens (42 ± 0.90 g) in a 7-week study. Broiler chicks were randomly allocated into one of the five dietary treatments (16 birds per pen with 10 pens per treatment). Dietary treatments consisted of corn-soybean meal based basal diet and the basal diet supplemented with blend of OAs and MCFAs at 0.25, 0.5, 0.75 g, and 1 g per kg of feed. In the current study, during the whole experimental period, the inclusion of the blend of OAs and MCFAs in the basal diet linearly improved (p < 0.05) body weight gain (BWG), feed conversion ratio (FCR), and dry matter digestibility. The increasing inclusion of the blend of OA and MCFA levels in the diets linearly decreased (p = 0.002) feed intake during d 1 to 7. Broilers fed diets containing different levels of the blend of OAs and MCFAs showed a linear increase (p = 0.006) in Lactobacillus concentrations and decrease (p = 0.014) in ammonia (NH3) at the end of the experiment. However, the blend of OAs and MCFAs did not affect carcass quality, E. coli, and Salmonella counts, as well as hydrogen sulfide and total mercaptans gas emission (p > 0.05). In conclusion, the blend of OA and MCFA supplementation positively influenced growth performance, DM digestibility, excreta Lactobacillus counts, as well as NH3 gas emission in broiler chickens.

A nine (9) weeks feeding trial was conducted on seventy two (72) day-old Indigenous turkey poults raised on deep litter to determine their growth performance, carcass and economic characteristics when fed three dietary treatments (T1, T2, and T3, containing 0%, 25% and 50% replacement of maize with millet respectively. The birds were divided into three replicates of 8 birds per replicate; making a total of 24 birds per treatment. At the end of the & week, 4 birds per replicate were transferred to specially-designed metabolism cages for a digestibility study involving the collection of faecal droppings; while at the end of the week of the experiments, two birds per replicate were randomly selected and slaughtered to determine their carcass characteristics. Turkey poults fed millet at 25 %replacement showed significantly (p<0.05) higher body weight gain, lower cost of feed per kg live weight gain and higher revenue generated per bird; but there were no significant (p>0.05) differences in the performance of birds on 0% and 50 % replacements for those parameters. Also, there were no significant (p>0.05) differences in feed intake and mortality across the treatments. Similarly, there were no significant (p>0.05) differences in nutrient digestibilities and carcass characteristics of the birds among the various dietary treatments. Therefore, it can be concluded hat millet cam be used to replace maize up to S0 % in the diets of turkey poults at the starter phase with no detrimental effects on their performance

The aim of the study was to investigate the effect of Bacillus licheniformis and salinomycin supplementation in broiler diets as individual factors or in combination on the growth performance, GIT morphometry, and microbiota populations. Four hundred one-day-old Ross 308 chicks were randomly distributed to four dietary treatments (10 replicates, 10 birds each). The following treatments were applied: NC—no additives; NC + SAL—salinomycin addition (60 mg/kg diet), NC + PRO—B. licheniformis DSM 28710 preparation (1.6 × 109 CFU/kg; 500 mg/kg diet), and NC + SAL + PRO—combination of salinomycin and B. licheniformis. Probiotic administration resulted in improvement (p < 0.05) of the performance parameters, including body weight gain (1–10 d, and 11–22 d) and feed conversion ratio (11–22 d, 1–36 d). An interaction (p < 0.05) between experimental factors was observed in terms of lower pH values in the crop (tendency, p = 0.053) and ceca. Both factors lowered the alpha diversity and Enterobacteriaceae and promoted Bacillaceae communities in the jejunum (p < 0.05). Interactions were also observed in terms of reducing Clostridiaceae in the ceca. In conclusion, the combined use of B. licheniformis and salinomycin in broilers’ diets had beneficial effects.

Hepatic Histopathology

Mycotoxins are toxic secondary metabolites produced by different strains of fungi, such as aspergillus, fusarium, and penicillium that can contaminate feed ingredients or the entire feed of poultry and animals. Mycotoxins can cause many serious complications to both humans and animals due to carcinogenic, mutagenic, and immunosuppressive disorders. Therefore, the present experiment aims to investigate the effect of broiler chickens’ diets supplemented with different levels of nanosilica (NS) as an adsorbent agent of mycotoxins on their growth performance and hepatic histopathology. Detectable levels of toxins were present in the feed before feeding, and all levels of mycotoxins were above the normal limit. A total of 180 one-day-old male Arbor Acres broiler chickens were allocated randomly to six treatment groups with three replicates per group, including ten chickens per replicate. The experiment lasted for five weeks, and dietary treatments included control diet and diets with four levels of nanosilica as 0.05%, 0.10%, 0.15%, and 0.20% as well as 0.50% bentonite (fixfin® Dry) diet. Bodyweight, body weight gain, average daily feed intake, and feed conversion ratio were measured weekly. At the end of the fifth week, six chickens per treatment were sacrificed to investigate the effects of NS and bentonite on carcass characteristics and hepatic histopathology. The results showed that providing broiler chickens’ diets with an adsorbent agent, such as NS or bentonite, can reduce the side effects of mycotoxins and enhance their growth performance. The best record was achieved with NS at 0.20%, compared with the control group and other dietary treatment groups. Accordingly, 0.20% of NS could be used in broiler chickens’ diets to minimize the harmful effects of mycotoxins.

Abstract This study addressed the effect of unconventional by-products on growth performance, carcass characteristics, some blood parameters, and caecal activities in New Zealand White (NZW) rabbits. A total of 48 weaned NZW rabbits (748 ± 9.50 g BW, 6 weeks old), randomly assigned into three treatment groups (16 each, individually housed), were fed a basal diet containing BBP at 0.00 (Control), 1.00 (Broc1) or 3.00 (Broc2) % on a dry matter (DM) basis as feed additives, for 8 weeks. The Broc2 rabbits showed the highest (P < 0.05) body weight gain and feed intake followed by the Broc1 group compared to the control one. Feed conversion ratio and performance index did not differ (P > 0.05) among treatments. Nutrient digestibility was higher (P < 0.05) for Broc1 and Broc2 rabbits compared to the control. Both Broc1 and Broc2 rabbits showed higher (P < 0.05) empty edible carcass, giblets, dressing, head, liver, heart and kidney weights, but showed a lower non-edible carcass weight compared to the control. Blood proteins and liver function enzymes were increased (P < 0.05) whereas the glucose, total cholesterol, uric acid and creatinine were decreased (P < 0.05) in Broc1 and Broc2 rabbits compared to the control. The caecal concentration of total volatile fatty acids was increased (P < 0.05) but that of ammonia was decreased (P < 0.05) with Broc1 and Broc2 groups of rabbits compared to those of control. Thus, dietary supplementation of BBP at 3% of DM in rabbits’ diets could improve their growth performance, carcass traits, liver function and blood profile as well as the caecal fermentation parameters.

A total of 600 one-day-old male Ross 308 broiler chickens with an average body weight of 43.00 ± 0.42 g were used in a 35 d growth assay to investigate the supplemental effects of three levels (600, 1200, and 1800 β-glucanase units kg−1) of β-glucanase on growth performance, nutrient digestibility, blood parameters, and meat quality in wheat–barley–soybean-meal-based broiler diet. During days 19–35 and overall period, chickens’ body weight gain and feed conversion ratio were significantly (P < 0.05) improved linearly following the levels of β-glucanase supplementation. The digestibility of crude protein and gross energy were significantly (P < 0.05) increased linearly with the levels of β-glucanase supplementation. Significant linear increase (P < 0.05) due to increasing β-glucanase supplementation was observed for blood urea nitrogen (BUN) concentration. Increasing β-glucanase supplementation did not influence (P > 0.05) the meat quality. In conclusion, broiler diets supplementation with increasing β-glucanase could improve the growth performance, enhance the digestibility, and modulate the concentrations of BUN linearly. Meat quality was not influenced.

A study was carried out to determine the effect of Crina Poultry Plus®, a natural blend of essential oils and benzoic acid. on the growth performance, carcass yield and nutrient digestibility of broiler chickens. Six treatment diets were formulated by the addition of Crina Poultry Plus (CPP®) at 0, 0.2, 0.3, 0.4, 0.5 and 0.6g/kg of feed. Two hundred and forty day-old chicks were allocated to the six dietary treatments with each treatment having four replicates. Each replicate had 10 broilers. The parameters measured were live weight, live weight gain, feed intake, feed conversion, protein efficiency ratio, carcass and organ    characteristics, nutrient utilization and feed cost benefit. Results of growth performance showed that there were no significant differences (P>0.05) across the treatment groups, but birds fed diets supplemented with CPP® had significantly heavier body weight (BW), higher average daily weigh gain live weight gain and similar feed conversion ratio when compared with the control group. The dressing percentage, thigh, drum stick, breast cut and back cut were not significantly (P>0.05) different across the treatment groups but those fed diet supplemented with CPP® had higher values when compared with the control diet. The supplementation of CPP® improved nutrient digestibility in broiler chickens. Birds fed diet containing 0.6g of CPP® had numerically lower cost per kg of weight gained compared to other treatment groups. It can be concluded that the addition of 0.6 g CPP® in broiler diets improved performance, carcass, organ characteristics and nutrient utilization of broilers.

The purpose of the research was to investigate the effects of including potato peels (PP) in broilers diet with exogenous enzymes supplementation on feed intake (FI), body weight gain (BWG), nutrient digestibility and carcass parameters. For this purpose, five iso-caloric and iso-nitrogenous rations were formulated with different levels of PP (0, 5, 10, 15 and 20%). Experimental diets were supplemented with a blend of exogenous enzymes (Xylanase, Mannanase, Protease, Cellulase). A total of four hundred male broiler chicks (day old) of 38 ± 3 gram were randomly distributed into 5 experimental groups in such a way that each group had 8 replicates and each replicate had 10 birds. Results revealed that the inclusion of PP @ 5% with exogenous enzymes had similar FI, BWG and nutrients digestibility with control. However, the inclusion of P @ of 10, 15, and 20% with exogenous enzymes in the broiler diet adversely affected the BWG, feed conversion ratio and nutrient digestibility ( p < 0.05). Results of carcass parameters were not affected ( p > 0.05) by dietary treatments. Based on findings, it is concluded that 5% addition of PP with exogenous enzymes could be practiced in broiler diet without any adverse effect on the performance of commercial broilers.

Aims: An experiment was conducted to investigate the comparative efficacy of two probiotics of different origins (yeast and bacterial based) on the growth performance and carcass characteristics of broilers chicken. Place and Duration of Study: The study was conducted at Krishi Vigyan Kendra, Purnea between January, 2020 to March, 2020. Methods: Two hundred and forty, day old chicks were kept and were randomly divided into 4 groups (A, B, C and D) and each group had 2 replicates of 20 chicks. Four (A, B, C and D) iso-caloric and iso-nitrogenous (ME 3000 kcal/ kg and CP 21.56%) broiler starter and finisher (ME 3000 kcal/ kg and CP 18.75%) diets were formulated containing Saccharomyces cerevisiae, Bacillus cereus toyoi and mixture of both @ 0.2% except group A which was control. Birds were raised for first week on commercial diet. Broiler starter and finisher diets were fed from 8-28 and 29-42 days, respectively. Results: A significant (P<0.05) effect was observed on overall performance of the birds fed diet containing probiotics. Probiotics in feed at 0.2% Saccharomyces cerevisiae supplementation improved body weight gain (+12.7%), feed intake (3.8%) and feed conversion efficiency (-8.7%) compared with the control diet. Among groups, no significant differences were observed in carcass traits but highest dressing percentage was recorded in group-B followed by group-C than group-D and lowest in control group. Conclusion: The result indicated that the addition of probiotics in feed containing 0.2% Saccharomyces cerevisiae improved broiler growth performances and it is beneficial to be used as supplement in feed of broiler chickens.
