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.

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.

The objective of this study was to evaluate the effects of Pediococcus acidilactici (P. acidilactici) and Saccharomyces cerevisiae (S. cerevisiae) on the growth performance, intestinal lesions and ileal Clostridium perfringens (C. perfringens) count of broiler chickens challenged with C. perfringens induced sub-clinical necrotic enteritis (NE). A total of 150 broiler chicks, allocated into five treatment groups (6 replicates of 5 chicks/cage), were reared in cages for 29 days: T0 (control group, not infected, not supplemented); T1 (infected with C. perfringens, not supplemented); T2 (infected with C. perfringens and coccidia, not supplemented); T3 (infected with C. perfringens and coccidia, supplemented with P. acidilactici); T4 (infected with C. perfringens and coccidia, supplemented with S. cerevisiae). The parameters analyzed were: body weight gain, feed intake, feed conversion ratio, mortality, intestinal lesion score and ileal C. perfringens enumeration by quantitative real-time PCR. The challenge resulted in impairment of growth performance, increased lesion score (≤ 2) and overgrowth of the C. perfringens population. However, the dietary inclusion of P. acidilactici or S. cerevisiae caused a significant improvement in feed conversion, net reduction of gut lesions, as well as a decrease in the intestinal C. perfringens population. In conclusion, these results suggest that dietary supplementation with probiotics (P. acidilactici or S. cerevisiae) could be beneficial to alleviate the negative effects of subclinical NE in broiler chickens.

Abstract Climate change and the lack of conventional feed ingredients have made edible insects a highly nutritious alternative to feed production. The use of insects as food may help solve socio-economic and environmental problems around the world and be in line with the United Nations Sustainable Development Goals. In this study, the growth performance and intestinal morphology of broiler chickens were evaluated under the influence of adding different levels of Tenebrio molitor larvae meal (TM meal) to their diets. One hundred eighty day-old broiler chickens were divided into 3 treatments and 5 replications (12 chickens/pen). The experimental diets included a control diet and treatments containing 2.5 and 5% TM meal, which were fed to birds in the starter (0-10 days) and grower (11-25 days) stages, and during the final period (26-42 days), all birds were fed a regular finisher diet. The results showed that the diet containing TM meal had no remarkable effect on the mortality rate and feed intake (FI) of broilers (P > 0.05). In the period of starter, the addition of 2.5% TM meal to broilers diet increased body weight gain (BWG) than the control group (P £ 0.05). Also, the use of 2.5% TM meal in the starter period showed a significant effect on reducing the feed conversion ratio (FCR) compared to the birds fed by the control diet (P £ 0.05). Besides, the height of the villus, the depth of the crypt, and the ratio of them were not altered among the different treatments (P > 0.05). Overall, it can be concluded that TM meal could improve growth performance in the starter period, and had no negative effects on broilers' performance and intestinal morphology in all the periods of the experiment.

Probiotics are beneficial bacteria that had been used in poultry industry as alternative sources for antibiotic. The aim of this study was to determine the effect of probiotic mixed with cassava leaves (Manihot esculenta) on Cherry Valley Duck (Anas platyrhynchos domesticus) growth performance, carcass characteristics and meat quality. Lactobacillus spp. was used in this experiment to see its effectiveness in enhancing quality of cassava leaves as potential feed towards optimum growth performance of ducks like body weight gain, feed intake and feed conversion ratio, carcass characteristics and meat quality. 34 tails of Cherry Valley ducks aged 14 days with average weight of 500 g were randomly assigned to four treatments in triplicates. Treatments for the 35 days feeding trial were T1 at 0% probiotic + 75% commercial diet + 25% cassava leaves (control), T2 (0.15% probiotic + 75% commercial diet + 25% cassava leaves), T3 (0.30% probiotic + 75% commercial diet + 25% cassava leaves) and T4 (0.45% probiotic + 75% commercial diet + 25% cassava leaves) respectively. Proximate analysis was also conducted to determine nutritional content like protein, lipid, moisture, ash and fiber. Results show that supplementation of probiotic at 0.15% Lactobacillus spp. into 25% of cassava leaves and 75% commercial pellet gave highest body weight gain (BWG), low feed conversion ratio (FCR), highest carcass yield and good meat quality. It can be concluded that inclusion of probiotic at 0.15% in cassava leaves as duck’s diet gives good growth performance and may become an alternative super diet for duck in future.

Feeding Trial

This study was carried out to evaluate the growth performance and carcass characteristics of finisher broiler chickens fed diet containing cooked cocoyam tubermeal as energy source in place of maize. The proximate composition of cooked cocoyam tubermeal showed that it contained 13.11% moisture, 2.60% ash, 3.90% crude protein, 9.45% crude fiber, 1.85% ether extract and 70.13% NFE. In the finisher feeding trial, the cooked cocoyam tubermeal was used to replace maize at levels of 25%, 50%, 75% and 100% respectively in the control diet. Each finisher diet was fed to a group of 30 finisher broiler chicken for 4 weeks using completely randomized design. Each treatment was divided into 3 replicates of 10 broiler chicks each. The birds were kept on deep litter and were given feed and water ad-libitum. Parameters measured include ifinal body weight, body weight gain feed intake, feed conversion ratio, carcass characteristics and economics of production. In the finisher feeding trial, the feed intake of the finisher broilers on diets 2, 3 and 4 were similar and compared favourably with those on the control diet. The finisher group on 100% CCYM (diet 5) recorded the lowest feed intake possibly because of the dustiness of the feed. The body weight gain of the finisher broilers on diet 2 (25%) cooked cocoyam tubermeal compared favourably with the control group and was significantly (P<0.05) higher than those on other diets. It appeared that the finisher broilers could not tolerate high levels of cooked cocoyam meal due to dustiness of the feed and its anti-nutritional factors. The cost of production per kg finisher broilers was cheapest for diet 5(100% CCYM) (N356.72) and the costliest was for diet 3(50% CCYM) (N588.28). The internal organs expressed as percent of the live weight were not affected by the treatments. In terms of carcass characteristics, the finisher broilers on diet 2(25% CCYM) recorded the highest breast muscle which was significantly different (P<0.05) from other groups. There were no significant different (P>0.05) on percent back cut, drumstick, head, shank, thigh, neck and wings of the finisher broilers on all the treatments. There were no significant differences (P > 0.05) in percent dressed weight of the finisher broilers on cooked cocoyam based diets. The results of the trial have shown that cooking cocoyam corms (Xanthosoma sagittifolium) for 30 minutes was effective for reducing the cyanide oxalate, tannin, phytic acid and saponin content and that cooking did not affect the proximate composition of tannia. Cooked cocoyam tubermeal could be used to replace maize up to 25% in the diet of finisher broiler chicken without affecting body weight gain, feed intake and feed conversion ratio as indicated in this study.

Cecal Microbiota

Probiotics can promote the health and growth performance of animals through modulation of intestinal microbiota. When used as a feed additive, they have the potential to minimize or abolish the use of antibiotics. In this study, we investigated the effect of the probiotic strain Bacillus amyloliquefaciens TL on the growth performance and cecum microflora composition in Cobb 500 broiler chickens. In total, 180 broilers were randomly divided into three groups—each group comprised 4 pens, and each pen contained 15 chickens. The three groups were fed either a control diet, or a diet supplemented with either the antibiotic chlortetracycline or B. amyloliquefaciens TL. Broilers were weighed, and cecum contents were collected on days 7, 14, 21, and 35, respectively. The broilers in both the antibiotic and probiotic groups exhibited significant weight gain compared with controls, exhibiting increases of 16.02% and 13.40%, respectively, after 35 days (P<0.01). Similarly, the feed conversion ratio (FCR, 1–35 days) of broilers in the chlortetracycline and B. amyloliquefaciens TL groups was lower than that of the controls. HiSeq high-throughput sequencing of 16S rRNA of the cecal microbiota was performed on days 7, 14, 21, and 35, respectively. The Firmicutes/Bacteroidetes ratio was higher in the chlortetracycline and B. amyloliquefaciens TL groups than in the control group on days 14, 21, and 35, and especially on day 21. The prevalence of genera Oscillospira, Ruminococcus, Butyricicoccus, and Faecalibacterium (Firmicutes) was higher in the antibiotic and probiotic groups, while that of Bacteroides, Parabacteroides (Bacteroidetes), and Lactobacillus was higher in the control group. In this study, the changes in the microbiota of the probiotic group were similar to those in the antibiotic group. These results suggest that the probiotic strain B. amyloliquefaciens TL can modulate the cecal microbiota of broilers similar to chlortetracycline.

Three groups of cockerels were fed with a control diet, with a diet contaminated with T-2 and HT-2 toxin (0.31 and 0.26 mg/kg) or with that containing a combination of T-2 and HT-2 toxin (0.32 and 0.25 mg/kg) and aflatoxin B1(AFB1, 0.38 mg/kg) for 21 days. Body weight gain and feed conversion ratio did not differ significantly among the groups. Malondialdehyde concentration of the liver was lower in the group fed the diet contaminated with the combination of T-2 + HT-2 toxin and aflatoxin B1as compared to the control group or the group fed T-2 + HT-2 toxins. Reduced glutathione (GSH) content of the liver was lower in the T-2 + HT-2 group than in the group fed a combination of T-2, HT-2 and aflatoxin. Reduced glutathione content of the heart was higher in the T-2 + HT-2 group than in the control group. Mycotoxin contamination had no effect on glutathione peroxidase (GSH-Px) activity in comparison to the control, but significantly lower GSH-Px activity was found in the heart of chickens in the T-2 + HT-2 + AFB1group than in the T-2 + HT-2 group. In this study, T-2 + HT-2 toxin and aflatoxin B1contamination of the diets did not affect the production traits adversely and did not exert additive effects on lipid peroxidation and on the glutathione redox system.

The present study aimed to assess the effect of dietary betaine (B) and/or creatine (C) on performance and thermoregulatory responses of broiler chicks. Indian River broiler chicks, fitted with compact thermosensors, were reared to market age (five weeks). The chicks were randomly distributed into four treatment groups, in a 2 × 2 factorial arrangement of treatments—basal control diet (Control group: CONT; B−/C−); 1 g betaine/kg feed (Betaine group: BETA; B+/C−), 1.2 g creatine monohydrate/kg feed (Creatine group: CRET; B−/C+), and combination (Betaine and Creatine group: COMB; B+/C+) of both supplements. At 31 days of age, 20 chicks from each group were exposed to acute heat stress (A-HS) for 3 h (34.45 ± 0.20 °C), and hemogramic profiles were screened before and after. Performance parameters (feed intake, body weight gain, and feed conversion ratio) were reported on a weekly basis, and carcass meat quality was evaluated at the end of experiment. Redness of breast was higher due to B and C treatments separately than the CONT group (B by C interaction; p < 0.05). Compared to the CONT, dietary supplements alleviated hyperthermia responses, with B alone being more efficient than C or COMB treatments. The mitigation of hyperthermia is likely mediated by enhancement of water balance indicators. Although not efficient in improving growth performance, dietary B and/or C are efficient in improving thermophysiological performance and survival of finishing broiler chicks under A-HS.

This study aimed at investigating the effect of a functional synergistic feed additive blend, containing organic acids and ß-1,4 mannobiose, on cecal Salmonella counts and growth performance of broiler chickens. A meta-analysis combining 13 individual studies, executed in Salmonella-challenged broilers comparing a control diet with and without the synergistic blend, was performed. Cecal Salmonella colonies and overall growth performance were measured. Raw data from all studies were combined and analyzed using PROC MIXED in SAS, taking the within and between-study variation into account. In the first 14 days post-inoculation (DPI), cecal Salmonella was reduced by 0.429 log CFU/g (p = 0.011, n = 10 comparisons from five studies) when feeding the synergistic blend compared to the control group. During 15–34 DPI, the overall means were not different between treatments (0.069 log CFU/g; p = 0.519, n = 12 comparisons from eight studies). The feed conversion ratio was improved when feeding the synergistic blend compared to the control diet (1.474 vs. 1.482, respectively; p = 0.002). In conclusion, feeding a synergistic blend, containing organic acids and ß-1,4 mannobiose amongst other ingredients, reduced cecal Salmonella counts during the first 14 DPI and improved growth performance of Salmonella challenged broilers compared to a control diet.

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.
