We evaluated the influence of enzymatic supplementation on the growth performance and cecal microbiota of broilers. A total of 2160 1-day-old male chicks were used in a 3 × 2 × 2 factorial arrangement (three corn hybrids, two drying temperatures −80 and 110 °C, with or without the inclusion of an enzymatic blend (amylase, xylanase, and protease) (20 birds/pen, n = 9). For all performance and digestibility parameters, we observed, in general, isolated effects of the corn hybrids and drying temperature. Birds that received the enzymatic blend in the diet showed better weight gain from 1 to 21 days (d) and better digestibility coefficients of nutrients at 42 d. Birds fed diets with corn dried at 80 °C showed a better feed conversion ratio from 1 to 42 d. At 21 d of age, enzymatic supplementation had positive effects on jejunum morphology. Enzyme supplementation increased the abundance of the phylum Tenericutes, class Bacilli and Mollicutes, reduced Clostridia, and increased the abundances of the families Lactobacillaceae, Anaeroplasmataceae, and O_RF39;F. In conclusion, the addition of amylase, xylanase, and protease led to a better nutrient digestibility, performance, and intestinal morphology. In addition, enzyme supplementation changed the diversity, composition, and predicted function of the cecal microbiota at d 21.

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.

An experiment was conducted to evaluate the effects of Bacillus coagulans ATCC 7050 (B. coagulans) on the performance, intestinal morphology and microflora of broiler chickens. Six-hundred 1-day-old broilers were randomly assigned into five treatment groups with four replicates for 42 days. There were five dietary treatments: negative control, positive control (antibiotics, 200 mg/kg zinc–bacitracin), 0.10, 0.20 and 0.25 g/kg B. coagulans. Dietary B. coagulans improved feed conversion ratio throughout the entire experimental period compared with the negative control (P = 0.02). Dietary B. coagulans significantly increased the number of lactobacilli (P = 0.01) and tended to decrease coliform bacteria (P = 0.06) in the duodenum. Dietary B. coagulans tended to increase villous height (P = 0.08) but had no effect on crypt depth in the jejunum. There were no significant differences (P > 0.05) in serum cholesterol, triglyceride, high density lipoprotein cholesterol and low density lipoprotein cholesterol between groups. In conclusion, the present data indicate that administration of B. coagulans ATCC 7050 improved feed conversion ratio in broiler chickens, possibly via improving the balance of intestinal microflora.

A 56 –day study was conducted to determine the growth performance and nutrient utilization of broiler chickens fed with two varieties (white and yellow) of cassava grit based diets. A total of 240 one day- old unsexed Arbor acre broiler chicks were assigned to eighty dietary treatments in a 2 x 4 factorial arrangement using completely randomized design. Diets were formulated to include two varieties of cassava, TME 419 (white) and TMS 01 1368 (yellow) at four inclusion levels (0, 25, 50 and 75%). Each treatment consisted of 30 birds and three replicates of 10 birds each. Data was collected on growth performance and nutrient digestibility at the end of the starter (4th week) and finisher (8th week) phases. At the starter phase, birds fed 50% white cassava grits diet had the highest (P < 0.05) final weight and weight gain (730.00 and 693.67g/bird). At the finisher phase, birds fed 50% yellow cassava grits diet had the highest (P < 0.05) final weight and weight gain (2235.60 and 1454.00g/bird), respectively while the least final weight and weight gain values (2008.80 and 1267.80g/birds) were obtained in birds fed the control diet. At the starter phase, birds fed 75% white cassava grits diet had the best (P < 0.05) feed conversion ratio of 2.18, while birds fed 25% yellow cassava grits diet as well as those fed the control diet had the least (P < 0.05) feed conversion ratio of 2.62 and 2.51 respectively. Birds fed 50% yellow as well as those fed 75% yellow cassava grits diets had the highest dry matter and crude fibre digestibility at the starter and finisher phases, respectively. In conclusion the substitution of maize with white cassava grits up to 50% level improved growth performance at the starter phase. However, either white or yellow cassava can be substituted for maize up to 75 % at the finishing phase.

The eight-week feeding trial was conducted to evaluate the nutrient digestibility and growth performance of broiler chickens fed raw or processed Senna obtusifolia seed meal (SOSM). Six experimental diets were compounded to contain 0% SOSM and 20% each of the raw, boiled, soaked, sprouted and fermented SOSM respectively. Two hundred and sixteen (216) broiler chicks were randomly allotted to six (6) dietary treatments in a randomised complete block design with three (3) replicates containing 12 chicks each. Data were collected on nutrient digestibility, feed intake, weight gain, feed conversion ratio and mortality. The result of productive performance indicated that feed intake, weight gain and feed conversion ratio were significantly (P<0.05) depressed in broiler chickens fed raw, soaked and sprouted Senna obtusifolia seed meal. However, broiler chickens fed fermented SOSM showed better (P<0.05) productive performance that was close to those fed the positive control diet (0% SOSM). The mortality rate did not reveal any particular trend. However, the low mortality rate recorded in the different treatments indicated broiler chicken can tolerate up to 20% of either raw or processed SOSM. Broiler chickens fed raw SOSM recorded lower values for dry matter (63.06%), crude protein (52.46%), ether extract (53.88%), crude fibre (30.72%) and nitrogen-free extract (46.11%) digestibility than those fed the other processed SOSM. The nutrient digestibility of broiler chickens fed fermented SOSM was significantly (P<0.05) better followed by those fed boiled Senna obtusifolia seed meal. For instance, broiler chickens fed fermented Senna obtusifolia seed meal recorded the highest crude protein and ether extract of 69.91 and 70.03% compared to the other processing methods. It can be concluded that 20% fermented SOSM can be incorporated in the diets of broiler chickens with acceptable depreciation in biological performance. Slightly lower levels of boiled SOSM can be included in the diet of broiler chickens but the levels should be ascertained in further studies.

The Laetiporus sp. is a fungal species that is traditionally used for medicinal purposes. This study investigated the effects of the Laetiporus sulphureus fermented product (FL) as a feed supplementation on the antioxidant activities, the intestinal Tight Junction (TJ) mRNA expression, and the intestinal morphology of broiler chickens. Four-hundred one-day-old male broilers (Ross 308) were randomly allocated to five experimental diets: (1) a corn-soybean meal basal diet (control), (2) a basal diet replaced with 5% Wheat Bran (5% WB), (3) a basal diet replaced with 10% WB (10% WB), (4) a basal diet replaced with 5% FL (5% FL), and (5) a basal diet replaced with 10% FL (10% FL). The FL-supplemented groups exhibited a better feed conversion ratio in the overall experimental period compared to the WB and control groups. The serum antioxidant profiles of 35-day-old broilers showed that, compared to the control and 10% WB groups, the 5% FL supplementation group had a significantly increased superoxide dismutase activity, while it down-regulated the concentration of malondialdehyde in the serum (p < 0.05). The assessment of selected antioxidant gene expression showed that the 5% FL group significantly elevated heme oxygenase-1 and nuclear factor erythroid 2–related factor 2 expression, compared to the control and WB groups (p < 0.05). Furthermore, both of the FL supplemented groups had a significantly higher expression of glutathione peroxidase and catalase, compared to that of the WB and control groups in the jejunum (p < 0.05). The TJ mRNA expression in the jejunum showed that 5% FL significantly elevated the zonula occludens-1, claudin-1, and mucin-2 expression (p < 0.05), while 5% and 10% FL supplementation significantly improved OCLN expression in both the jejunum and ileum, compared to control group (p < 0.05). The intestinal morphology of 35-day-old broilers showed that a 5% FL supplementation significantly increased the villus height in the ileum and jejunum, compared to the WB and control groups (p < 0.05). Moreover, the 5% and 10% FL supplementation groups had a significantly higher villi:crypt ratio in the ileum, compared to the WB and control groups (p < 0.05). To conclude, FL supplementation improved the antioxidative status, the TJ mRNA expression, and the intestinal morphology, and it was accompanied by a lowered feed conversion ratio in broilers. Finally, 5% supplementation had the overall best results in improving the antioxidant status, TJ mRNA expression, and intestinal morphology of broilers.

The study was designed to evaluate the effects of administering extracts of garlic and Aloe vera in water on the growth performance and apparent nutrient digestibility of broiler chickens. One hundred and fifty, day old, Arbor acre chicks were used, in a completely randomized design, in seven treatments and each with three replicates. The experiment lasted for eight weeks. The garlic and Aloe vera extracts together with the antibiotics control (Sulfaquinoxalina) were administered at different doses via drinking water consecutively for three days and alternately at week 1, 3, 5 and 7, respectively. Treatment 1 received commercial antibiotics (Sulfaquinoxalina) at 2.67 g in 4 litres of water. Treatments 2 and 3 each received 0.40 mL of garlic and Aloe vera extracts in 4 litres of water which translated to 400 ppm. Treatments 4 and 5 each received 0.80 mL of both extracts in 4 litres of water (800 ppm) while treatments 6 and 7 each received 1.20 mL of both extracts in 4 litres of water (1200 ppm), respectively. The parameters measured were mean body weight, mean body weight gain, mean feed intake, mean feed conversion ratio, mean protein and energy efficiency ratio and apparent nutrient digestibility of feed as a result of the various doses of garlic and Aloe vera. Results showed no significant (p>0.05) differences in all the growth performance parameters measured for the first four weeks (starter phase). Feed conversion ratio, protein efficiency and energy efficiency ratio were affected (p<0.05) across the treatment groups at the last four weeks (finisher phase) of the experiment, with broiler chickens administered 400 ppm of garlic extract (T3) showing better performance (2.44, 2.42, 0.14) compared to those fed treatment 6 and 7 (1200 ppm Aloe vera and garlic). The apparent nutrient digestibility of the broiler chickens for all the nutrients were significantly (p<0.05) affected at both the starter and finisher phases of the experiment but no particular trend was observed. The total digestible nutrients were therefore calculated and it showed that birds administered 400 ppm Aloe vera extract (T2) at the starter phase and both 800 ppm of Aloe vera (T4) and garlic (T5) at the finisher phase, had better (p<0.05) total digestible nutrients compared to the control (90.69 vs 88.31; 91.10, 90.60 vs 88.59, respectively). It is concluded that the doses of 400 ppm (garlic) and 800 ppm (Aloe vera) extracts via drinking water improved feed conversion ratio, protein and energy efficiency ratio of broiler chickens at the finisher phase.

A four-week experiment was conducted to investigate the effect of Maxigrain® enzyme supplementation on performance, nutrient digestibility and economic indices of broiler finishers fed soaked and sun-dried cassava peel meal (CPM) based diet. CPM was included in the diets replacing maize at 0%, 25%, 50% and 75% respectively on a weight for weight basis. Diets with 25%, 50% and 75% CPM were supplemented with Maxigrain® at 100mg/kg. Two hundred (200) Anak, day old broiler chicks were randomly allotted to four dietary treatments in a completely randomized design (CRD) with five replicates containing ten birds each after balancing for live weight. Feed and water were supplied ad libitum throughout the 4 weeks period of the experiment. Data on the body weight and feed intake were collected on a weekly basis and that of weight gain and feed conversion ratio(FCR) were calculated fortnightly while data on apparent nutrient digestibility was collected towards the end of the experiments in a metabolic trial. Data on feed costanalysis were calculated using the prevailing current market price of feed ingredients. The result shows that average weight gain and feed intake were significantly affected (P<0.05) by dietary treatments. Birds on 50% CPM enzyme diet had a significant (P<0.05) higher weight gain and feed intake followed by those on 75% CPM diet as compared to control group. Enzyme supplementation of the CPM diets produced a slight improvement in feed conversion ratio than the control diet. Feed cost/kg weight gain significantly (P<0.05) decreased with increasing levels of enzyme supplemented CPM. Profit margin generated were higher (P<0.05) in bird fed enzyme treated CPM diet group. Apparent nutrient digestibility of the birds revealed a significant (P<0.05) variation in all parameters with the exception of dry matter. Digestibility values of the birds were observed to increase as the inclusion level of enzyme supplemented CPM increased across the diet. Therefore, it is concluded that enzyme supplemented CPM could replace 75% of maize in broiler finisher diet without any deleterious effect however, supplementing CPM with enzyme Maxigrain® at 50% replacement level for maize resulted in a more profitable performance as well as improved nutrient digestibility and is hereby recommended for poultry farmers.

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.
