One hundred and eighty, 4-week old broilers were used to study the performance of broiler finishers fed diets containing raw, boiled or dehulled pigeonpea seed meals included at levels of 30 and 40% of the diets in a 33 x2 factorially designed experiment. Performance criteria were daily weight gain, feed intake, feed conversion ratio (FCR), protein efficiency ratio (PER), nutrient utilization and final liveweight of the broilers at the end of 8" week. Results showed that dehulled seed meal diet produced broilers with the highest daily weight gain, final liveweight and protein efficiency ratio, lowest feed intake, FCR and daily protein intake. Broilers fed boiled seed meal diet performed significantly better than those fed raw seed meal diet in all measurements. Broilers fed on 30% inclusion level of PPSM gave better results than those on 40% which significantly depressed growth rate, feed conversion efficiency, protein efficiency and increased protein intake. The interaction between processing methods and inclusion levels were not significant. There was a higher nutrient utilization of dehulled and boiled PPSM diets by broilers than the raw seed meal. Increase in the level of inclusion generally decreased protein retention except for the dehulled PPSM diet. It is concluded that a better option is to dehull boiled pigeonpea seeds and include the meal at not more than 30% of the whole ration for broiler finishers.

Monodora Myristica

Fungal infected feedstuffs are denatured in nutrients and cause them to develop off flavors that often dampen the appetite of livestock and poultry. In this study, the effect of toasted African nutmeg (Monodora myristica) spice in Aspergillus flavus-infested diets on growth performance of broilers was investigated in a 2 x 3 factorial experimentthat lasted for 42 days. Three out of 6 dietary treatments were infected with 1mg of pure culture of Aspergillus flavus and toasted Monodora myristica spice included at 0%, 0.5% and 1.0% while the other 3 diets were infection-free with 0%, 0.5% and 1.0% Monodora myristica inclusion respectively. Each treatment was replicated three times at 30 chickens per replicate. Infection status was significant (P<0.05) for daily weight gain, feed conversion ratio (FCR) and protein efficiency ratio (PER). Daily weight gain, feed conversion ratio and protein efficiency ratio were 134.19g/bird/day, 39.23g/bird/day, 3.59g/bird/day and 1.10g/bird/day, respectively for the non-infected diets. The aflatoxin infection from Aspergillus flavus was observed to reduce (P<0.05) feed intake to 130.51g/bird/day and weight gain (33.67g/bird/day). FCR and PER were also reduced (P<0.05) by the presence of aflatoxin from Aspergillus flavus in the diet. Effect of Monodora myristica supplementation on feed intake, average daily weight gain, FCR and Protein efficiency ratio was significant (P<0.05) for all the measured parameters. The Feed intake, average daily weight gain, FCR and protein efficiency increased (P<0.05) as Monodora myristica inclusion level increased. Feed intake (119.8g/b/d), daily weight gain (28.90g/b/d), FCR (4.28) and PER (0.94) were observed in the Monodora-free (0%) diet. 0.5% and 1.0% levels of Monodora inclusion produced similar (P>0.05) effects on all the growth parameters but were higher than the control. The interaction of aflatoxin infection and Monodora inclusion level were significant for all the growth parameters. The interaction of aflatoxin infection x Monodora inclusion levels recorded feed intake of 107.97g/b/d, 137.36 and 146.19g/b/d respectively for 0, 0.5 and 1.0% Monodora; 22.27g/b/d, 37.87g/b/d and 40.83g/b/d daily weight gain and 4.85%, 3.63% and 3.58% FCR. The interaction effect of Monodora inclusion level in infection-free diets on the birds feed intake were 131.65g/b/d, 147.24g/b/d and 123.67g/b/d respectively for 0%, 0.5% and 1.0%. The interaction effect at 0.5% inclusion level x non-infected diet was significantly higher (41.31g/b/d) than that at 0% inclusion level on daily gain. However, the daily weight gain of 40.83g/b/d observed in the interaction of 1.0% Monodora level x aflatoxin -free diet similar (P<0.05) to that observed in the 0.5% inclusion level. The feed conversion ratio produced by the interactions at the three different levels (0, 0.5 and 1.0%) in the Aspergillus-free diets were (P>0.05) 3.71, 3.57 and 3.49 respectively while PER were (P<0.05) 1.05, 1.13 and 1.11 respectively. The Monodorafree diet recorded 9.26% drumstick, 2.26% liver 0.65% kidney and 2.43% gizzard, while the diet that had 0.5% Monodora myristica yielded 2.12% liver and 2.29% gizzard. Inclusion of Monodora up to 1.0% recorded 1.63% liver weight. Aspergillus flavus alone caused a reduction in live weight, dressed weight, thigh, kidney, breast meat, gizzard and an enlargement in the liver. Monodora myristica inclusion level also affected (p<0.05) all the parameters except dressed weight, thigh and back cut. Kidney and liver were observed to decrease as the level of inclusion of Monodora myristica increased. The interaction of Monodora myristica and Aspergillus flavus on the parameters were significant (p<0.05). From the results, Monodora myristica may be beneficial to poultry farmers, since about 90% of the poultry feed ingredients especially grains are constantly exposed to aflatoxin infection from Aspergillus flavus and other mycotoxin infections which hinder maximum nutrient utilization and affect the rate of conversion of feed.

The performance and nutrient retention of broilers fed raw (RMD), toasted (TMD), boiled (BMD), soaked and boiled (SMD) or no (NMD) Mucuna cochinchinensis seed diets at both starter and finisher phases were assessed using 400 broiler chicks. The birds were fed a common proprietary feed (Top Feed) until 2 weeks of age, followed by a treatment diet for 3 weeks of the starter period, then 5 weeks on the finisher diet. At the starter phase, RMD significantly (P < 0.05) decreased liveweight, daily weight gain, protein efficiency ratio and encouraged poorer feed conversion ratio and higher cost per kilogram weight gain when compared with other diets. TMD decreased (P < 0.05) only the protein efficiency ratio. RMD also decreased (P < 0.05) retention of dry matter (DM), crude protein (CP), crude fibre (CF) and energy while TMD decreased (P < 0.05) retention of only DM, CP, and energy. At the finisher phase, RMD also significantly (P < 0.05) decreased daily weight gain, protein efficiency ratio and feed conversion ratio and increased cost per kg weight gain, while TMD decreased (P < 0.05) only the protein efficiency ratio and feed conversion ratio. RMD again decreased (P < 0.05) retention of DM, CP, CF and energy, while TMD, as in the starter phase, again decreased (P < 0.05) retention of DM, CP and energy. On a cumulative basis, RMD adversely affected (P < 0.05) all the parameters under investigation. TMD affected (P < 0.05) only the feed conversion ratio, protein efficiency ratio and cost per kg weight gain. Boiling Mucuna cochinchinensis, therefore, encourages significantly better performance of chicks, higher nutrient retention and lower cost per kg weight gain than toasting, whereas soaking before boiling does not add any advantage to boiling alone.

A total of 324 local pullet chicks (1- 8 weeks) were used for the research project to evaluate the feeding value of raw and boiled pigeon pea seed meal (PSM) on their growth performance. Nine iso-caloric and isonitrogenous diets were formulated, with raw and boiled pigeon pea seed meal at inclusion levels of 0%, 15%, 20%, 25% and 30%, respectively. There were 36 chicks per treatment replicated into 3 at 12 chicks per replicate. There were significant interactions between form and PSM levels on the final live weight, daily feed intake and daily protein intake. Final live weight of pullets fed both raw and boiled PSM followed the same trend, pullets fed control (0%) and 15% raw PSM 128.10 and 132.33g respectively performed better than the rest of the treatment levels but statistically similar at all levels. Daily feed intake and daily protein intake showed significant interaction among the treatments. Pullets fed control (8.95g) and raw diets (8.79g) consumed more feed than pullets fed boiled PSM II (105.05g), III (117.77g) IV (91.27g) and V (112.80g) diets. Daily weight gain, feed conversion ratio and protein efficiency ratio had no significant (P>0.05) interaction between form and treatment groups for the pullets. 30% PSM raw or boiled can be fed to local pullet chicks without any deleterious effect on the growth performance.

The scarcity and increasing cost of conventional plant protein sources prompted researches into potential feed resources that are relatively of less importance to man. Loofah gourd (Luffa cylindrical (M.J. Roem) is a plant that is widely available in most tropical, subtropical and temperate region. In Nigeria it grows luxuriantly uncultivated and the sponge is often used for domestic cleaning while the seeds are discarded. The seeds were de-hulled, milled and fed at 0, 5, 10, 15, and 20% dietary levels of inclusion as partial total replacement for groundnut cake. One hundred and fifty (150) day-old broiler chicks were divided into five (5) groups and each was fed the experimental diets for fifty six (56) days in a completely randomised design (CRD) arrangement. Data collected included the average feed intake (AFI), average weight gain (AWG), live weight (LW) feed conversion ratio (FCR), protein efficiency ratio (PER), haematology indices such as pack cell volume (PCV), red blood cell count (RBC), white blood cell count (WBC) and haemoglobin (Hb), serological variables such as Alanine aminotransferase (ALT), aspartic aminotransferase (AST), alkaline phosphatase (ALP) and carcass characteristics. Loofah gourd seed meal (LGSM) significantly (P<0.05) depressed the feed intake, weight gain, live weight, and protein efficiency ratio of the birds as the dietary inclusion of LGSM increased in a similar trend. AFI, AWG, and PER were significantly highest (P<0.05) in birds on the control group (125.88 g/day, 51.37 g/day, and 1.81 respectively) and lowest in those on 20% LGSM (62.88 g/day, 19.35 and 1.39 respectively). PCV and Hb were significantly highest (P<0.05) in birds on the control group (10.46 g/dl and 34% respectively) and lowest in those on 15% LGSM (21%) and 10%LGSM (6.98g/dl) respectively. Birds fed with the control diet had the lowest (P<0.05) AST (86.13 U/I), ALT (5.67 U/I) and ALP (112,338.90) and those on 20% LGSM had the highest AST (104.18 U/), ALT (10.98 U/D while the highest ALP (201,762.90) was in birds fed 10% LGSM. Weight of liver and spleen expressed as percentage of live weight were significantly lowest in birds on the control group (1.38 and 0.18 respectively) and highest in those on 15% LGSM (4.08 and 1.50 respectively). The increase in liver and spleen weight coupled with increased serum enzymes activities suggest the presence of anti-nutrient in LGSM. Hence, the use of LGSM beyond 5% level of inclusion is not beneficial in the production of broiler.

A 56-day feeding trial using twelve (12) crossbred weaner pigs of 8 weeks of age and average weight of 10.58±17kg were used to investigate the effect of different dietary levels of raw bambara groundnut offal on their growth and carcass characteristics. Four diets were formulated to contain raw bambara groundnut offal at 0, 10, 20 and 30%, designated T1, T2, T3 and T4 respectively. The weaner pigs were randomly assigned to the four (4) diets in a completely randomized design (CRD) experiment. Chemical composition of the test ingredient and diets were analysed. Data collected include feed intake, weight gain, feed conversion ratio (FCR), protein efficiency ratio (PER) and economics of production. The carcass characteristics were also evaluated. The proximate composition of the experimental diets revealed that the crude protein and ether extract contents of the diets decreased with increased levels of raw BGO in the diets, but the converse was true for crude fibre and ash contents. The results indicated significant differences (p< 0.05) in daily weight gain (DWG). feed conversion ratio, protein efficiency ratio, cost (N) /kg of seed and cost (N)/kg weight gain. The values were. 0.34, 0.29, 0.28 and 0.22kg for DWG, 3.03, 3.62, 3.55 and 4.30 for FCR in T1, T2, T3 and T4 respectively. Protein efficiency ratio, values were 1.84, 1.54, 1.57 and 1.29. Cost/kg of feed values were 75.69, 70.13, 64.56 and 56.10, and cost (N)/kg weight gain were 229.32, 253.86, 229.20 and 253.69 for the treatments respectively. The results of the carcass evaluation indicated significant differences (p< 0.05) for ham and trotters. The values were 0.31, 0.35, 0.37 and 0.32 for ham in T1, T2, T3 and T4 respectively. The values of trotters were, 64.6.56.99, 56.98 and 53.66 among the treatments. For organs characteristics, the results indicated significant differences (p< 0.05) for lung, kidney, liver and spleen. The values of the lungs were, 11.20. 11.25. 9.40 and 8.97 among the treatments. The values of kidney and liver were, 3.34, 2.86, 3.72 and 3.14, and 24.28, 28.57, 22.55 and 27.70 respectively. The inclusion of up to 20% raw BGO in the diet of weaner pigs recorded comparable daily weight gain, feed conversion ratio and cost/kg weight gain with the group fed the control (0%raw BGO). Further studies involving heat treatment of the BGO might be necessary to improved nutrient utilization by the animals, and also increase inclusion level.

Aim: The objective of the study was to assess the effect of supplementation with dietary shatavari, Asparagous racemosus root extract on growth, feed conversion and nutrient utilization in Labeo rajasthanicus. Methodology: Two-hundred-seventy fingerlings of equal size (8.19±0.03g) were stocked in 18 fibre reinforced plastic tanks following complete randomized design. Six iso-nitrogenous (30% crude protein) and iso-caloric (390 kcal digestible energy per 100 g) diets were prepared with graded level of ethanolic shatavari root extract, i.e., 0.00, 0.15, 0.30, 0.45, 0.60, 0.75 g kg-1 and designated as control, T1, T2, T3, T4 and T5 were fed to L. rajasthanicus twice a day for 45 days. The growth performance, feed conversion and nutrient utilisation were considered as response parameters. Results: Significantly (P<0.05) higher growth performance (weight gain %, specific growth rate, net yield and mean daily weight gain percentage) and better feed conversion and nutrient utilization (protein efficiency ratio and lipid efficiency ratio) were observed in T1 group than in other experimental groups. Interpretation: Based on these findings, it can be concluded that ethanolic extract of shatavari root can be used as a growth promoter and can be included at the supplementation level of 0.15 g kg-1 diet for Labeo rajasthanicus.

The inclusion of up to 20% raw BGO in the diet of weaner pigs recorded comparable daily weight gain, feed conversion ratio and cost/kg weight gain with the group fed the control (0% raw BGO). Further studies involving heat treatment of the BGO might be necessary to improved nutrient utilization by the animals, and also increase inclusion level.

This study was conducted to assess the effects of abattoir wastes (bovine blood and rumen content mixture) on the haematology and growth performance characteristics of broiler birds. One hundred and twenty (120) unsexed day old Abor acre broiler chicks were randomly assigned to 4 treatments and replicated 3 times in a completely randomized design (CRD) experiment. Four experimental diets were formulated to meet the nutrient requirement of broilers such that the birds were fed sundried abattoir waste (bovine blood and rumen content mixture) included at 0%, 5%, 10% and 15% representing Diet 1, 2, 3 and 4 respectively, with Diet 1 as the control. Each dietary treatment consists of 30 birds with 10 birds per replicate. The experimental diets and clean water were supplied at- libitum throughout the experimental period. Data were collected on feed intake, daily weight gain, final body weight, weight gain. Feed conversion ratios were calculated. Blood samples for hematology was collected, analyzed and recorded. At the end of the 56 days feeding trials, data collected on different parameters were subjected to analysis of variance (ANOVA). Results showed that mixtures of bovine blood and rumen content significantly (P<0.05) improved the final weight (1767.02g -1931.44g), weight gain (1367.02g -1528.44g), feed intake (107.47g -118.99g) and feed conversion ratio (4.87 – 4.08) of the broilers. Significant (P<0.05) improvements were observed on the RBC, WBC, MCV, MCH, eosinophyls and the lymphocytes of the haematological parameters of the broilers. These results showed the complementary potentials of bovine blood and rumen content mixture in broiler diets, which can be included up to 15% in the ration of broilers without detrimentally affecting the growth performance and haematology of the broilers.
