Two experiments were conducted with broiler chickens from 1 day old to 4 wk of age to determine the nutritional value of unextracted and extracted dehulled canola rapeseed (DCS). In exp. 1, raw or autoclaved DCS at levels of 10 and 20% of the diet were compared with extracted DCS at levels of 5 and 10%. The inclusion of extracted DCS in the diet had no adverse effects on the performance of chicks. Dietary levels of 10 and 20% raw DCS resulted in a decrease in feed intake (P > 0.05) and weight gain (P < 0.05) and an increase in feed/gain ratio (P < 0.05). The performance of birds fed autocalved DCS was intermediate between that of birds fed raw or extracted DCS. Experiment 2 involved a comparison of extracted DCS at levels of 0, 10, 20 and 30% of the diet with variable or constant levels of dietary lysine and sulphur amino acids. Dietary levels of 20 and 30% extracted DCS resulted in a progressive decrease (P < 0.001) in feed intake and weight gain, and an increase (P < 0.001) in feed/gain ratio. Lysine supplementation improved the nutritional value of extracted DCS. It was concluded that canola rapeseed should be heated before feeding to broiler chickens. Autoclaved or extracted DCS may be included in the diet of broiler chickens at levels of 10% with no reduction in growth rate.

In a completely randomized designed, two hundred and forty day-old broiler chicks were randomly assigned to four dietary treatments containing 0, 2.5, 5.0 and 7.5mg kg-1 Lcarnitine. Each of the diets contained equal amount of maize and cashew nut reject meal (CNRM). The birds were randomly divided into sixteen groups of fifteen chicks each after weight equalisation. Each diet was assigned to four groups of birds representing four replicates per experimental diet. Measurements taken during starting and finishing phase included average live weight, average weight gain, average feed intake while feed to gain ratio was calculated. Nutrient digestibility of the experimental diets was also evaluated. Results between 0-4weeks indicated that body weights ranged from 673.71g in the birds that received 2.5mgkg-1 to 700.21g in the birds that received 7.5mgkg-1 L-carnitine. Weight gain and feed intake values were significantly (P<0.05) affected by L-carnitine levels. Feed to gain ratio values were elevated when birds were fed 0 and 2.5mgkg-1 L-carnitine levels. Evaluation of nutrient utilization showed a significant (P<0.05) influence on crude protein and ether extract values. Between 5-8 weeks of rearing, feed intake increased (P<0.05) as Lcarnitine levels increased in diets while lower (P<0.05) feed to gain value was recorded at high level of dietary L carnitine. Nutrients utilization parameters were not affected (P>0.05) during finishing phase. Overall results showed that highest body weight and weight gain were obtained in the group that received 7.5mgkg-1 L-carnitine supplementation. The study showed that supplementing CNRM diets up to 7.5mgkg-1 is beneficial to growth and utilization of broiler chickens. However, this was more effective at the starter phase.

A feeding trial was conducted to evaluate the growth performance and nutrient of broiler chickens fed varied levels of steam-treated Cattle Rumen Epithelia Scrapings (CRESM) in replacement for fish meal at 0, 25, 50, 75, and 100% level. Two hundred and four (240), one-day old Abor Acre strain of broiler chickens used for the study were randomly divided into 5 treatments of four (4) replicates each. There were 12 birds per replicate to a total of 48 birds per treatment in a completely randomized design. Data were collected on the feed intake, weight gain, feed to gain ratio, feed cost per kilogram weight gain at the starter and finisher phases while digestibility trial was conducted at the finisher phase. The results indicated that feed intake (44.15, 48.20, 48.87, 47.18 and 49.30g) and weight gain (20.73, 24.13, 24.63, 23.69 and 23.34g) for 0, 25, 50, 75 and 100% CRESM, respectively were higher (P<0.05) and feed: gain ratio lower in birds that received diets containing CRESM at starter phase. Feed cost and feed cost per kg weight gain decreased with increased level of CRESM at this phase. At the finisher phase, feed cost per kilogram weight gain (₦260:01) of treatment five (100% inclusion of CRESM) was the lowest (p<0.05) compared with other inclusion while the control was the highest. It was concluded that 100% fishmeal could be replaced with steam-treated CRESM in broiler diets, thus ultimately reducing the production cost and increasing the profit accruable to farmers.

An eight-week feeding tial was conducted to investigate the effect of feeding alkali processed soyabeans to broilers.  Soyabeans were processed in aqueous solutions of sodium chloride, sodium sesquicarvonate (trona) and alum respectively. The concentration of each of the salts was 3%. The soyabeans, after drying, were used in compounding 3 diffefrent diets. The control (T1) contained roasted soyabeans while diets T2 , T3 and T4 contained NaCl, trona and alum respectively. Broiler feeding lasted for 8 weeks starting from day - old. The results indicated that feeding NaCl processed soyabeans to broilerss significantly (P<0.05) depressed growth rate, feed consumption and body gain. NaCl treated soyabeans produced feed/gain ratio, protein efficiency ratio (PER), carcass and organ proportion  comparable to thr control. The growth rate, feed intake and weight gain of NaCl to sufficiently inactive trypsin inhibitors and remove a substsntisl proportion of polyphenols and oligosaccharides in soyabeans. It was concluded that since alkaline salts are cheap and readily available all the year round their use in processing soyabeans should be encourage.

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.

Two experiments were conducted to study the effects of either soluble or insoluble fibre naturally occurring in wheat and oats, on technical pellet quality and nutritional value for broiler chickens. In exp. 1, the effects of insoluble fibre were studied by mixing diets based on wheat or naked oats with either coarse or fine oats hulls followed by pelleting. Hull inclusion increased (P < 0.05) starch gelatinisation, especially in the diets based on oats. Addition of finely ground oats hulls improved pellet durability, in particular after storage, while no such effect was observed for coarse oats hulls. Oats hulls inclusion caused a more elastic pellet with higher breaking resistance (P < 0.05). Lower (P < 0.05) energy consumption was observed for diets based on oats compared with wheat, while no effect of fibre inclusion on energy consumption was found. In exp. 2, the influence of pelleting on the viscosity effect of soluble fibres in diets based on wheat or oats was studied. A significant increase (P < 0.05) in intestinal viscosity of broiler chickens was observed for all batches of grain exposed to steam pelleting. Viscosity was doubled (P < 0.05) with wheat diets, while the increase in viscosity was even greater in oat diets. In wheat diets, feed intake and weight gain was reduced (P < 0.05), while feed conversion ratio was not affected. Steam pelleting of oats reduced (P < 0.05) feed intake and weight gain, and increased feed conversion ratio (P < 0.05). The improvements (P < 0.05) in metabolisable energy and dry matter digestibility in wheat diets was not consistent with the observed increases in viscosity or with the results obtained with oats. Key words: Soluble fibres, insoluble fibres, viscosity, starch gelatinisation, steam-pelleting

Two trials were conducted with Nicholas strain turkeys. In trial 1, 300 male poults were reared to 49 days using either initial stages of 'large-turkey' feeding regime, or a situation allowing for diet self-selection of protein and energy. Within these programs, diets were supplemented with 10 ppm avoparcin, while a comparable number of controls received no growth promoter. Avoparcin improved growth rate (P < 0.01) irrespective of age, and improved feed utilization to 35 days of age. This effect was not confounded with the form in which diets were offered. In a second trial a 'broiler-turkey' feeding schedule was used, with birds slaughtered at 88 days. Diet treatments consisted of a control diet containing 33 ppm robenz and test diets containing either 33 ppm robenz + 10 ppm avoparcin or 10 ppm avoparcin alone. Avoparcin improved weight gain (P < 0.05) irrespective of coccidiostat inclusion. Feed utilization and carcass grades were not influenced by diet. The 7% improvement in body weight noted here with avoparcin was substantially greater than that previously observed with broiler chickens.

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.
