Potato Meal

The performance of Ross broiler chickens fed on Sweet Potato Meal (SPM) as a dietary source of energy was studied. The study was carried out at both starter (0-4 wks) and finisher (5- 9 wks) phases. In both phases, SPM was incorporated at graded levels of 0. 10, 20, 30, 40 and 50 percent and dietary proteins were adjusted to make the diets iso-nitrogenous. In the starter phase, three replicates of I5 birds each were randomly allocated to each of the 6 treatments in a completely randomized design (CRD) experiment while the number of birds per replicate was reduced to 14 for the finisher phase using the same experimental design. Parameters measured or calculated include feed intake, body weight gain, feed efficiency, feed costs, feed cost/kg weight gain, mortality and carcass characteristics. The results showed similar trends in both phases. Differences in the feed intake were not significant (P>0.05) while weight gain, feed cost/kg weight gain and total cost of rearing the birds decreased significantly (P<0.05). The Control, 10% 20% and 30% SPM diets gave similar weight gain and feed gain ratio. The Control gave the best performance in both starter and finisher phases, although its performance was not significantly different (P>0.05) from that of the 30%SPM diet Sweet Potato Meal level had no adverse effects on mortality and carcass characteristics. It is therefore concluded from this study that SPM should not be included beyond 30% level in a maize-based diet when protein requirement of birds is satisfied.

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.

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.

Phytase is essential for enhancing nutritional value of feed and improving animal growthperformance and health. A study was conducted to evaluate the influence of Smartchoicephytase enzyme supplementation in the diet of starter broiler chickens. A total of 150 Rossstrain broiler chicks were used for the study and allotted to five treatment groups of 30 birdseach. Each group was further divided into three replicates of 10 birds per replicate. Five isonitrogenous(21.40% CP) and iso-caloric (2975.40 kcal/kg ME) dietary treatments werecompounded to contain 0g/100kg (T ), 10g/100kg (T ), 15g/100kg (T ), 20g/100kg (T ) and 1 2 3 425g/100kg (T ) of a commercial Smartchoice phytase enzyme preparation for 28 days in a 5Completely Randomized Design (CRD). Feed and water were provided to the chicks adlibitum.Daily feed intake and weekly body weight were measured. The result showed that thedaily feed intake and daily protein intake were not affected (P>0.05) by Smartchoice phytaseenzyme supplementation. Final live weight, daily weight gain and total weight gain weresignificantly different among treatments. Protein efficiency ratio were significantly (P<0.05)higher in T (2.10) than T (1.80) but similar to T (2.05), T (2.05) and T (1.96). Feed 1 5 2 3 4conversion ratio was significantly (P<0.05) different in T5 (2.58) and T (2.02) but similar 1(P>0.05) in T (2.02), T (2.28), T (2.31) and T (2.38). Mortality was lowest in T5. Total feed 1 2 3 4cost per bird and daily feed cost per bird were not affected (P>0.05) by Smartchoice phytaseenzyme supplementation while cost per kg of feed and daily feed cost per bird were notsignificantly (P>0.05) affected. The findings from this study showed that Smartchoicephytase enzyme could be supplemented up to 20g per 100kg in the diet of starter broilerchickens.

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.

The experiment was carried out to determine the effect of replacement of maize with sweet potato (Ipomoea batatas lam.) on growth performance and cost of feeding weaner rabbits (Oryctolagus cuniculus). A total number of thirty-six (36) weaned rabbit of mixed sexes were used for the experiment. The rabbits were allotted randomly into four dietary treatments and replicated thrice with three rabbits per replicate and were designated: control (T): normal 1 compounded diet without sweet potato peel meal, T had the compounded feed which 5% 2 sweet potato peel meal, T had compounded diet with 10% sweet potato peel meal and 3 treatment four (T) had the compounded diet with 15% sweet potato peel meal. The 4 experiment lasted eight weeks and data were obtained on growth performance and cost benefit. The parameters considered on growth performance include initial weight, final weight, total body weight gain, daily weight gain, weekly weight gain, daily feed intake, total feed intake and feed conversion ratio while that of cost benefit include cost of purchasing different experimental feed stuff. The results obtained on growth performance showed that there were no significant differences (p>0.05) in the parameters monitored. Cost of feeding was also not significantly different (p>0.05). However, higher profit index (174. 64) was recorded in T1 and lower benefit cost ratio (166.68) was recorded in T4 for total cost of feed intake per rabbit. In conclusion, sweet potato peel meal can be uses as a good replacement for maize in rabbit production without any adverse effect on the performance of rabbit.

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.

The progressive increase in the cost and scarcity of conventional feedstuffs, especially energy and protein sources has resulted into a continuous effort in researching into the possible utilization of the under - exploited wild legumes in poultry feed formulation. Several Researchers had reported on the utilization of Moringa oleifera leaf meal in poultry diets whereas; few reports exist on the utilization of Moringa seed. Therefore, this study wasconducted to evaluate the effect of graded dietary levels of moringa seed cake (MSC) on the performance of broiler chickens. A total of 195, one day old Arbor Acre broiler chicks were randomly assigned into five dietary treatments of moringa seed cake, each treatment having three replicates in a completely randomized design. MSC was included at levels of 0, 5,10, 15 and 20% respectively. Feed and water were given ad- libitum. Proximate composition ofMSC showed that it is high in energy, crude protein and ether extract with3304. 39 ME kcals/ kg, 32.49 % and 17.70%, respectively. Birds fed 5% MSC diet were better than the birds on the other levels of MSC diets in terms of growth and carcass characteristics. The results obtained from growth study revealed a significant declined in, final weight, weight gain, feed intake, and feed conversion ratio as the inclusion levels of MSC increased beyond 5% in thediets. The birds on control diet had the best result in terms of final weight , daily weight gain and daily feed intake of 2974g/bird, 52.4g/bird / day and 107.51g/bird/ day respectively followed by those fed diet containing 5% MSC with 2183.4g/bird, 38.24/bird /day and 95.66g/bird /day respectively. whereas, the birds fed 20% MSC had the least (P>0.05) final weight, daily weight gain and daily feed intake of 560 g/bird, 9.26g/bird /day and 33.51g/bird/day respectively. Carcass characteristics followed similar trend as the growth parameters. Hematological indices showed significant differences across the dietary treatments, however, the results were within the normal range except for the white blood cell. It can therefore be, concluded that the inclusion of MSC in broiler chicken diet should not exceed 5% for optimum growth and general performance.

This study aimed to assess the effect of stocking density of 10, 12, 14, and 16 birds m?2 on performance, carcass and cut yields, productivity, and bone development of broiler chickens Cobb 500®. The experimental design was completely randomized design with four treatments (stocking densities) and four replications. The assessments were performed weekly at 1, 7, 14, 21, 28, 35, and 42 days. The best live weight result was found at a density of 10 birds m?2 in the period from 1 to 7 days. No effect of density was observed on feed intake and weight gain. From 1 to 14 days, the best live weights were found at densities of 10, 12, and 14 birds m?2, in addition to a higher feed intake at densities of 10 and 12 birds m?2. Weight gain was better at a density of 10 birds m?2, showing no differences from densities of 12 and 14 birds m?2. In the period from 1 to 21 days, live weight and weight gain were higher at densities of 10, 12, and 14 birds m?2. The highest feed intake was observed at a density of 10 birds m?2, which showed no difference from the density of 14 birds m?2. A difference (P < 0.05) was observed for live weight, weight gain, and feed intake of animals reared at densities of 10, 12, and 14 birds m?2 for the phases from 1 to 35 days and the total phase from 1 to 42 days of bird age when compared to 16 birds m?2, which presented lower performance. However, feed conversion of 1-7, 1-14, 1-21, 1-35, and 1-42 days and carcass and cut characteristics showed no significant differences for all treatments. On the other hand, productivity was higher in the treatments with 14 and 16 birds m?2, but without difference between each other. No interaction (P > 0.05) was observed between stocking density and age for the assessed bone parameters. Similarly, no difference (P > 0.05) was observed for bone development of broiler chickens reared at different stocking densities for the studied parameters. Thus, the increased density of 10 or 12 birds m?2 to 14 birds m?2 has no influence on zootechnical performance, carcass and cut yields, and bone development, but increases broiler chicken productivity reared in a conventional shed without air conditioning.

The effect of replacing an antibiotic growth promoter in the diet with a probiotic on growth performance, carcass characteristics and nutrient retention was studied in broilers (Vencobb 430) fed with and without meat cum bone meal (MBM). This experiment which lasted for 42 days consisted of six dietary treatments viz., basal diet (BD), basal diet with MBM (MBM), basal diet with antibiotic (AB), basal diet with probiotic (PB), basal diet with MBM and antibiotic (MBM+AB) and basal diet with MBM and probiotic (MBM+PB). Three-hundred, day-old chicks were randomly allotted in the beginning to these six groups. Body weight gain, feed intake and feed conversion ratio were significantly (P less than 0.05) affected at 4th week of age. Overall, highest body weight gain was recorded in birds fed with AB and PB. Inclusion of probiotic in MBM also showed improved body weight gain when compared to MBM group. Highest feed intake and feed conversion ratio was recorded with AB and PB groups. Birds supplemented with MBM+PB showed improved feed intake and feed efficiency when compared to MBM+AB and MBM diet supplemented groups. Higher dry matter, crude protein, calcium and phosphorus retention (P less than 0.05) was observed in birds supplemented with PB or AB in diet without MBM when compared to their control. In MBM supplemented groups addition of PB or AB improved crude protein retention. Birds supplemented with PB or AB with or without MBM showed a significant (P less than 0.05) increase in thigh yield and a non significant reduction in fat yield when compared to their control groups.

Whole canola/pea (WCP, 1:1 wt/wt) or whole canola/canola meal (WCC, 3:1 wt/wt) were heat-processed using a commercial pellet mill prior to incorporation in broiler starter (0–20 d) and finisher diets (20–40 d). The pelleted blends readily disintegrated in the preparation of the mash diets. Body weight gain of broilers (0–40 d) fed WCP (0, 10, 20, or 30%) or WCC (0, 5, 10, or 15%) declined linearly with level of dietary inclusion (P < 0.01). Feed intake declined curvilinearly (P < 0.01) with both blends, with lower intake most apparent at the higher inclusion levels. Feed/gain increased for broilers fed WCP or WCC (P < 0.01). Overall broiler mortality declined incrementally with inclusion of WCP (P < 0.07) or WCC (P < 0.03) in the diet. Although there was no distinct limitation on the dietary inclusion levels of either blend, the low feed intake with broilers fed 15% WCC indicated that its level should not exceed 10% of the diet. Key words: Canola seed, canola meal, peas, broiler chickens
