The effects of wet feeding and a multi-enzyme preparation on the nutritional value of wheat screenings (WS) for broiler chicks were investigated. In total, 540 1-day-old Ross-308 broiler chicks were fed a corn–soybean meal-based diet up to 29 days of age. At that time, the birds were randomly assigned to nine diets in a completely randomised design with a 3 × 3 factorial arrangement, including three levels of WS (0%, 25% and 50%, WS0, WS25 and WS50 respectively) and three processing methods (no processing, enzyme supplementation and wet feeding). The enzyme mixture contained endo-1, 4-β-xylanase (200 FXU/g), endo-1, 4-β-glucanase (50 FBG/g), endo-1, 8-β-glucanase (21 FBG/g), hemicellulase (3000 VHCU/g), α-galactosidase (3 GALU/g) and protease (260 U/g) and was supplemented at a level of 6 g/kg of diet. The inclusion of water in wet diets was in the extent of 1.2 kg/kg of diet. During the period from 29 to 49 days of age, feed intake was not affected (P > 0.05) by the inclusion of WS in the diet, whereas chicks fed the WS25 diet had a higher (P < 0.05) bodyweight gain than did those on WS0 diet. The feed conversion ratio (FCR) was improved (P < 0.05) by the inclusion of WS in the diet throughout the study. The feed intake was increased (P < 0.05) by enzyme supplementation to WS50 diet, while bodyweight gain was increased (P < 0.05) by wet feeding. Enzyme supplementation did not affect (P > 0.05) FCR, whereas wet feeding resulted in lower (P < 0.05) FCR over the entire study. The plasma concentration of glucose was increased (P < 0.05) by the inclusion of WS in the diet. The viscosity of the ileal digesta was higher (P < 0.05) in chicks receiving the WS50 diet than that in chicks receiving the other diets. The jejunal villus height was increased (P < 0.05) and the jejunal crypt depth was decreased (P < 0.05) by the inclusion of WS in diet. The jejunal crypt depth was greater (P < 0.05) in chicks receiving the wet diets than in chicks receiving the enzyme-supplemented diets (P > 0.05). In conclusion, the results from the present study indicated that broiler growth performance was improved by the inclusion of WS in the diet and also by wet feeding. These effects were largely compatible with the changes that occurred in the small intestine morphology, but not with those observed for ileal digesta viscosity.

An experiment was conducted to determine the influence of an acidifier as an alternative to antibiotics on the performance and gut morphology of broiler chickens. One hundred and eighty (180) 7-day old broiler chicks were randomly assigned to 3 dietary treatments of 4 replicates each. Each replicate had 15 birds. The diets fed to the birds were: Treatment 1- diet with neither antibiotic nor acidifier; Treatment 2- diet with antibiotic and Treatment 3- diet with acidifier. The antibiotic used was Enrofloxacin which was administered to the birds on Treatment 2 via their drinking water while the acidifier used was Biotronic SE (a combination of propionic and formic acids) which was added to the diet of birds on Treatment 3 at the rate of 4kg/tonne of feed. The experiment lasted 42 days. No significant differences were observed in the feed intake, final weight and weight gain of the birds on the different diets. Significant differences were however observed in the villus height in the duodenum and ileum of the birds. The crypt depth values in the different segments of the small intestines of the birds were not significantly affected by the different treatments.Key words: Organic acids, Biotronic SE, Enrofloxacin, Crypt, villus.

The growth performance, blood parameters and production cost of two hundred and fifty two (252) Abor acre plus broiler chickens fed sweet orange peel meal (SOPM) with and without enzymes were investigated. The experimental diets consist of control (T ), maize was 0 replaced with SOPM at 15, 20 and 25 % without exogenous enzymes to form T , T and T 1 2 3 respectively, and another supplemented with exogenous enzyme to form T , T and T 4 5 6 respectively. The birds were randomly allocated to seven treatment groups replicated three times to have 12 birds per replicate and were fed experimental diet ad-libitum for eight weeks. Result showed that broiler chickens fed control diet (T ) had significantly (P<0.05) 0 higher final weight (FW) of 2.44kg, weight gain (WG) of 42.91, feed intake (FI) of 86.53, better feed conversion ratio (FCR)of 2.01 and protein conversion ratio (PCR)of 0.44 compared to other dietary treatments. Broiler chickens fed T and T had significantly 1 4 (P<0.05) higher final weight of 1.98 and 1.98 kg, weight gain of 34.69 and 34.71 g and feed intake of 78.35 and 81.63 g respectively while significantly (P<0.05) least values of 1.75 and 1.80 kg final weight, 30.73 and 31.49 g weight gain and 69.47 and 71.84 g feed intake respectively were recorded in broiler chickens fed T and T . Haematological indices namely: 2 5 PCV, RBC, WBC and Hb were not significantly different (P>0.05) but MCV, MCH, MCHC, lymphocytes, heterophil, eosinophil and monocytes differed significantly (P<0.05). Serum biochemical indices namely total protein, albumin, globulin and uric acid were significantly (P<0.05) influenced by the experimental diets. Though, there was no detrimental effect of SOPM and enzyme on production cost as profit was made at all replacement levels of SOPM with and without enzyme treatment, but profit per bird (N) and cost to benefit ratio revealed the superiority of the broiler chickens fed control diet (T ). Based on the results obtained, 0 SOPM can replace maize up to 25 % without posing any deleterious effect on the broiler chickens growth performance, blood parameters and production cost. However, the cost to benefit ratio was compromised with the use of SOPM.

n eight week study was conducted to assess the performance, carcass characteristics and haematological indices of broiler chickens provided water from different sources. One hundred and fifty day - old broiler chicks (Arbor acre) were randomly allocated to five treatment groups (rain, stream, pipe borne water, well and borehole water respectively) in a completely randomized experimental design. The borehole water was obtained from a residential building, about 500 m to the experimental site (Federal College of Agriculture (FECA), Akure, Nigeria). Rainwater was harvested when it rained and was stored in plastic containers before it was used. It was not stored for more than three days before use. Stream water was obtained from a stream that flowed close to the students' residential area of FECA. It is sometimes drunk and is typical of streams that flow in a typical village community. Well water was obtained from a well sunk within the premises of the FECA. It was a well from where people fetched water for domestic use and was provided to the birds without prior treatment. Pipe borne water was obtained from the Water Corporation Mains that supplies FECA and Ijapo Estate, Akure. Results from the experiment revealed that there were no significant (P>0.05) differences among the treatments in terms of water intake, feed intake, weight gain, feed conversion ratio, carcass characteristics, relative weight of some organs, muscle dimensions and haematological parameters. Pipe borne water had the highest numerical values (P>0.05) for most of the performance and carcass characteristic indices measured, such as daily water intake (181.53±14.6), cumulative water intake (8.90±.71), daily feed intake (106.27±4.15), cumulative feed intake (5.21±0.20), daily weight gain (38.53±2.38), total weight gain (1.89±0.12), final weight gain (1.98±0.12), percent dressed weight (97.11±0.16%), percent eviscerated weight (81.86±3.26%), relative weights of drumstick (99.37±5.43g/kg), wings (89.10±9.69g/kg), chest (170.08±6.59g/kg) and back (159.40±18.90g/kg live weight) respectively. Water from different sources (rain, well, pipe borne water, borehole and stream) had no significant (P>0.05) effect on the performance indices, considered in the study for broiler chickens. This implies that the aforementioned water sources can be used to raise broiler chickens provided such water is free from any contaminants that could impair the health of the birds.

In this study, the effect of three different sources of maggot meals was conducted to evaluate the performance and slaughter characteristics of broiler chickens. Five diets were formulated to include Diet 1 (control) which contained 3.5 % fish meal, while Diets 2, 3 and 4 contained 3.5% maggot meal from broiler droppings (BMM),maggot meal from layers droppings (LMM) and maggot meal from rabbit faeces (RMM) respectively. Eighty (80) dayold unsexed Marshall Broilers were randomly allotted to four dietary treatments in a completely randomized design (CRD). Thedietary treatments had 20 birds each with two (2) replicates. Data were generated on proximate analysis and performance indices including feed intake and weight gain, slaughter characteristics and mortality rate. They were subjected to analysis of variance (ANOVA) and means significantly different were separated using Duncan's Multiple Range Test (DMRT) at 5% probability level. Results from proximate analysis showed that maggots from layer droppings had the highest crude protein and ether extract. Results on performance indices showed that birds fed on diet 3 (layer maggot meal) had significantly (P<0.05) best performance than others as regards feed intake. Layer maggot meal (LMM) in this study enhanced bestproductive performance compared to those from broiler and rabbit maggot.Birds fed layer maggot meal had the best (1.85) feed conversion ratio. They also had the best body weight gain (2501g) and feed intake (4627g). In conclusion, layer maggot meal is recommended as analternative animal protein source to expensive fish meal.
