Deciphering the Amendment-Induced Secretion of Ligninolytic Enzymes by Pleurotus pulmonarius

Pleurotus pulmonarius belonging to the white-rot fungal basidiomycetes group secretes extracellular ligninolytic enzymes for the degradation of agroresidues. The present study was carried out to evaluate the efficacy of different agro-residues for the enhanced production of ligninolytic enzymes and to authenticate their ability by protein analysis. The morphological and molecular sequences of white-rot fungi were characterised. Besides, the efficacy of organic and inorganic amendments in the secretion of ligninolytic enzymes by P. pulmonarius was characterised using SDS-PAGE and native PAGE analysis. The characterised strain of P. pulmonarius secreted enhanced laccase enzyme levels in the liquid medium through supplementation with organic and inorganic amendments. Wheat bran and groundnut cake each @5% enhanced secretions of Laccase, LiP and MnP. Copper sulphate at 150 μM enhanced the laccase enzyme and at 100 μM enhanced the LiP enzyme level by P. pulmonarius. Similarly, supplementation with manganese sulphate at 150 μM enhanced laccase, LiP and MnP enzyme levels compared to control. SDS-PAGE results showed protein banding patterns in the range of 50–85 kDa for the Lac enzyme in samples drawn from wheat bran and groundnut cake-supplemented substrates. Native PAGE results of laccase enzymes also showed that wheat bran (5%) + groundnut cake (5%) + CuSO4 (150 M) + MnSO4 (150 M) induced four laccase isozymes. Supplementing organic and inorganic amendments to the substrates would enhance the secretion of laccase enzyme that would aid in better breakdown of lignin.

​Effect of Inclusion of Moringa oliefera Leaf Meal on the Growth Performance, Nutrient Digestibility and Carcass Characteristics of Deccani Lambs

Background: Moringa (Moringa oleifera) is a highly valued plant grown in tropical and subtropical countries. Moringa has a high amount of crude protein, a well-balanced amino acid profile, vitamins and minerals and fewer quantities of antinutritive factors. Methods: Eighteen growing Deccani lambs of uniform body weight (14.22±1.5 kg) and age were randomly allotted to three treatment groups viz., 100 per cent groundnut cake (T1), 75% groundnut cake+ 25% Moringa oliefera leaf meal (T2) and 50% groundnut cake+ 50% M. oliefera leaf meal (T3) as a protein source in the concentrate mixture. The experiment was conducted for 90 days. Result: No significant difference was found in the fortnightly body weights of the lambs from 1st to 6th fortnights among three dietary groups. Total weight gain and Average Daily gain (ADG) were significant (P less than 0.01) among the treatment groups whereas DMI (kg/day), per 100 kg and FCR was non-significant. The digestibility coefficients (%) of all nutrients were non-significant (P greater than 0.05) except the NFE. Pre-slaughter weight, empty body weight, hot carcass weights and dressing percent on pre-slaughter weight and empty body weight were comparable among the three groups. Results of the present study indicated that inclusion of 25% Moringa oleifera leaf meal in concentrate mixture proved to be superior and improved the growth performance, digestibility of nutrients and carcass traits without any adverse effects on experimental lambs.

Carcass Traits, Organ Proportion and Bio-Economic Cost Benefits Analysis of Broiler Chickens Fed Different Dietary Plant Protein Sources in Sorghum-Based Diet

A 56-day study was carried out to evaluate the carcass characteristics and organ proportions of broiler chickens fed sorghum-based diets with varying plant protein. A total of 120 day-old broiler chickens from a reputable and disease free farm were used for this study. There were four treatments, each having thirty broiler birds replicated thrice with ten broiler birds per replicate using a Completely Randomized Design (CRD). The broiler birds were offered feed and water ad libitum. The growth parameters were taken on weekly basis. Carcass evaluation was carried out at the end of the trial. One bird per replicate was randomly selected, fasted over-night and slaughtered by severing the jugular vein. After scalding in warm water for about a minute, the feathers were manually plucked, each bird was cut into parts for carcass evaluation. The relative weights of the cut parts were as a percentage of dressed weight. The internal organs, such as heart, kidney, gizzard/proventriculus were all weighed separately and recorded using electric micrometer (3000g weighing gauge). The findings from this study showed that all the carcass parameters considered showed significant differences (p<0.05). Birds fed diet 3 gave the best live weight, slaughtered weight, defeathered weight, dressed weight and commensurate cut-parts. Soybean (whether cake or full-fat) demonstrate superiority over groundnut cake and cashew nut cake. Birds fed diet 3 gave the highest value of thigh, breast -cut, drumstick and wings, while birds fed diets 2, 1 and 4 gave less. The organ proportions of broiler chickens fed different dietary plant sources have all the parameters significantly difference (p<0.05), except the lungs though without any definite pattern. Average weight gain and feed conversion ratio were better (p<0.05) among birds fed diet 2, and 3. Cost benefits analysis per kilogram in naira terms for birds fed different plant protein sources in a sorghum-based diets were significant (p<0.05) among treatment levels. Least cost per kg feed was obtained in diet 1 (p<0.05). Cost of weight gained was (p<0.05) low in T1. Cost of feed consumed was low for diet T1 and T3. Revenue, gross margin and cost benefit ratio estimated were found to high (p<0.05) among T2 and T3. Broiler chickens fed diet 3 gave the best parameters. The actual contributions of the experiment, is to alternatively replace corn with sorghum completely at least cost with optimum performance.

Non-chemical strategies in integrated management of wilt and stem rot diseases of chrysanthemum

Wilt and stem rot caused by Fusarium oxysporum f sp. chyrsanthemi and Rhizoctonia solani are most devastating diseases, amounting to cause 18 -27 per cent loss under congenial environmental conditions in chrysanthemum. Due to many issues such as fungicide resistance, cost, and adverse effects, eco-friendly integrated approaches seem to be an applicable management method against the wilt and stem rot diseases of chrysanthemum. The objective of our present study was to evaluate the alternative methods such as soil amendments, biological agents and soil solarization (SS) alone and in integrated form which are cheap and easily adoptable having long-term benefits in combating the wilt and stem rot infection of chrysanthemum. Neem cake and cotton cake were found superior against Fusarium wilt pathogen with highest 68.11 per cent disease reduction while mustard cake showed highest effectiveness followed by neem and groundnut cakes to minimize the Rhizoctonia solani infection by 64.29 per cent. Fungal antagonists proved better in controlling disease compared to bacterial antagonist. For soil solarization, 25µ thickness polythene sheet resulted in less disease than 50 µ thickness. Integration of all the components resulted into excellent control of stem rot and wilt under field conditions due to additive effects. Maximum disease control (73.15 %) achieved in SS+ T. harzianum + Neem cake, SS+ T. harzianum + T. viride. A drastic decrease in the inoculums load of both pathogens recorded after two months period in solarized than unsolarized soils with varied microbial counts and almost negligible appearance of weeds in solarised plots.

Elucidating the energy-utilization patterns for five methods of groundnut cake (Kulikuli) production

Food industry remains an integral part of the energy-intensive industries. In order to minimise the operating and maintenance cost in the industry, the cost of energy consumption should be monitored. Therefore, energy requirements in groundnut cake production for five alternative methods were elucidated. Groundnut cake was produced using five different methods and energy used for each unit operation was calculated using standard equations. Major energy sources for the production of groundnut cake were fuel, human labour and electrical energy. Sensory attributes of the products were determined by panellists. Data were analyzed using descriptive analysis and analysis of variance at p≤0.05. Total energy consumed by the traditional and semi-mechanized processes 1-4 were 31,629.12 kJ, 8079.74 kJ, 7932.94 kJ, 8730.58 kJ, and 8519.8 kJ, respectively. Energy intensity for traditional and semi-mechanized processes 1-4 were 9210.93 kJ/kg, 2107.39 kJ/kg, 2069.10 kJ/kg, 2277.15 kJ/kg and 2222.17 kJ/kg, respectively. The frying process was the most energy intensive in both traditional and semi-mechanized process 3 with the energy of 13193.28 kJ and 2232.12 kJ, respectively. Peeling and slicing consumed the least amount of energy (60.4 kJ) in all processes. In semi-mechanized processes 1, 2 and 4, the dry-milling emerged the most energy consuming, with energy of 2240 kJ, 2240 kJ and 2145.6 kJ, respectively. Although, groundnut cake that was produced by traditional method was the most acceptable by the panellist, there was no outright rejection of any sample. Energy consumption pattern and quality attributes of kulikuli produced from traditional and semi-mechanisation of production methods were influenced by the type of unit operation, the technology involved and the size of the equipment used. Semi-mechanised methods required the low energy consumption in the production of acceptable kulikuli.

White lupin (Lupinus albus L.) is rich in quality protein, reduce malnutrition. This study was conducted to evaluate agro morphological traits in 5x5 simple lattice designs at Holeta Agricultural Research Center during 2018/2019 by using 25 white genotypes. This study was conducted to assess agro-morphological traits with grain yield and to evaluate the genotype correlation coefficient of grain yield to direct and indirect effects through path analysis. Numbers of pod per plant, seed weight per plant and number of seeds per pod at genotypic and phenotypic levels, days to first flowering at the genotypic level and plant height and stem thickness at phenotypic level showed positive and significant correlation with grain yield. While and number of branches per plant, numbers of seed per plant, pod length and pod thickness had negative significant correlation with yield at both levels. These traits had also high to moderate positive indirect effects on grain yield via each other and through other traits at the genotypic level, which suggested simultaneous selection for grain yield. Therefore, the results showed the presence of correlation, direct and indirect effects of traits on grain yield among white lupin was important to select white lupin depend on its agro- morphological and nutritional composition for improvement.

Determination of optimum blood meal level for performance of broilers under Sudan condition

Different unconventional feed stuffs are used in poultry production to decrease ration cost and the environmental, nutritional and economic benefits derived from the maximal utilization of animal blood. This study was established to assess the effect of feed partially replaced dried blood content supplemented on growth performance responses and carcass. In a feeding trial, 240 commercial broiler chicks a day old, with an average starting weight of 48.40± 1.50 g, Lehmann breed unsexed commercial broiler were randomly allocated to one of four dietary treatments in a completely randomized design. The dietary treatments consisted of the control diet, and three diets which contained varying levels of Sun-dried blood meals SDBM (3, 4 and 5 %) respectively. The experimental diets were formulated to be both isonitrgenous (22.5% CP) and isocaloric (3.10 Mcal /kg). Feed and water were provided adlibitum for a period of 6 weeks. Data for the entire 42 days growth assay indicate the concentration of SDBM in the diet had impact on feed intake. However, birds fed SDBM at 3 or 5% had better weight gains and feed efficiency (p < 0.05) than birds fed 4% SDBM and the SDBM free diet. Carcass yields were similar. Mortality was also unaffected by dietary treatments. In addition, Analysis of productive parameters indicated that dietary SDBM up to 5% had a positive effect on growth performance and that partial replacement of protein sources (blood meal and groundnut cake) with SDBM was possible.

Evaluation of selected organic residues as supplements on growth and yield of Oyster mushroom, Pleurotus florida

Introduction: The growth and yield of a mushroom are dependent on its ability to utilize the inherent nutrients in the substrate. In order to acquire a good knowledge of the mushroom fruiting substrates, the nutritional contents of the substrate can be improved by the addition of some nitrogenous supplementation to the substrate Methodology: The suitability of some locally available organic materials/wastes as yield boosters for the cultivation of Oyster mushroom Pleurotus florida was evaluated. Corn bran (CB), wheat bran (WB), rice bran (RB), palm kernel cake (PKC), groundnut cake (GNC), soya meal and poultry manure (PM) were separately added to sawdust from Gmelina aborea. Results: Data analysis indicated significant variations among treatments in all the parameters taken. The presence of the various additives in the substrate significantly enhanced the biological efficiency (BE) of the mushroom when compared to the control (p<0.05). P. florida had its highest BE (68.74%) on sawdust added with rice bran (RB) and its least on the control (17.98%). Days to mycelium colonization were shortest on CB (23) and longest on PM (39). Shortest days to primodia initiation were observed on CB (29) and the longest on PM (48). Also, protein content in the fruiting bodies was significantly highest in substrates added with PKC (30.98) and WB (30.94) (p<0.05) and least in control (22.48). Conclusion: It was evident that the inclusion of these additives significantly improved the growth, yield, and nutritional contents of the investigated mushroom. PKC and WB may be used to enhance both the yield and nutritional values of the mushroom.

Effect of partial replacement of protein supplement with silkworm (Bombyx mori L.) pupa meal on production performances in crossbred (HS × GH) grower pigs

Eighteen crossbred (HS × GH) castrated grower pigs (3 months old, body wt. ranged from 13 to 14 kg) were divided into three groups of six each in a randomized block design to investigate the partial replacement of conventional protein sources with silkworm pupae (Bombyx mori) meal on production performance. Three different diets were prepared for feeding of experimental animals. These were namely - T1: standard grower ration without silkworm pupa meal and designated as control diet, T2: standard grower ration supplemented with 1.5% silkworm pupa meal by replacing 2.5% protein supplements which include mixture of groundnut cake and soyabean meal and standard grower ration supplemented with 3% silkworm pupa meal by replacing 5% protein supplements. The pigs were fed on the experimental grower rations twice daily in the morning and evening. The average dry matter intake was found similar in T1, T2 and T3 groups. Digestibility coefficients (%) of dry matter, crude protein, ether extract and crude fiber was increased in silkworm pupa meal supplemented groups. Nitrogen balance (g/d) was found positive across all the groups and was increased in supplemented groups in comparison to control. The average body weight gain (g/day) was found higher in silkworm pupa supplemented groups. The cost (`/kg gain) was reduced in T2 and T3 groups in comparison to T1 group. The feed conversion efficiency (FCR) was higher T2 and T3 groups than control group. From this study, it is concluded that silkworm pupa meal can be supplemented @ 3% level by replacing 5% protein supplements in grower crossbred pigs to improve growth, nutrient utilization, feed conversion efficiency and also to reduce the feed cost.

Growth response and feed utilization in Clarias gariepinus fingerlings fed diets supplemented with processed flamboyant (Delonix regia) leaf meal

Expanding utilization of conventional fish feed ingredients by man and fish feed industries has necessitated consideration of cheaper and locally available alternatives. A 70-day feeding trial was conducted to assess the effect of substituting graded levels of sundried flamboyant (Delonix regia) leaf meal (SFLM) for groundnut cake on growth and feed utilization of 240 Clarias gariepinus fingerlings at six substitution levels of 0 (control), 20, 40, 60, 80 and 100% in 12 plastic aquaria (50 × 40 × 40 cm). Each dietary treatment was randomly assigned in two replicates each to the aquaria making 12 treatment units and each aquarium had 20 fish. SFLM supplemented diets and fish carcass were proximately analyzed using standard procedures. Mean weight gain (MWG), specific growth rate (SGR) and feed conversion ratio (FCR) were determined. Data obtained were analyzed using descriptive statistics and ANOVA at p ≤ 0.05. Crude protein was highest (68.89%) in fish fed with diet 4, least (64.61%) in fish fed with diet 1 (control) and significantly (p < 0.05) exceeded 60.54% of the pre-treatment fish carcass. Fish fed with diet 3 had significantly (p < 0.05) higher values of MWG (11.73 g), SGR (2.13%/day) and superior FCR (0.451) above which growth and feed utilization indices progressively declined with increase in the substitution level of SFLM. This study revealed that 40% substitution level of the SFLM resulted in the best growth and feed utilization in C. gariepinus. The study demonstrated the considerable potential of flamboyant leaf meal as an alternative protein source, therefore other processing methods are recommended to increase its utilization, reduce feed cost and maximize aquaculture profitability.

Birth Characteristics and Pre-Weaning Lamb Growth of Grazing Sudan Desert Ewes Supplemented in Different Reproductive Stages

This work was conducted to study effect of supplementary feeding at different reproductive stages on birth characteristics and pre weaning growth performance of lamb born to desert sheep (Hamari subtype) raised on natural range in West Kordofan State, Sudan. Ninety ewes of similar age and live weight were used in the study. Ewes were divided into three feeding group of 30 animals each. Group A was given concentrate supplement for one month before mating, one month during mating, and one month before lambing; group B was given the supplement for one month during mating and one month before lambing, while group C was left as a control group kept on natural grazing. The concentrate diet consisted of sorghum grains 15 %, groundnut cake 20 %, molasses 15 %, wheat bran 25 %, groundnut hulls 23 %, salt 1 % and 1 % limestone, and was offered at a rate of 500 gm./ewe/day. All animals were allowed to graze on natural range and were watered every 2-3 days. The result indicated that birth weight in general and that of ram lambs was heavier in concentrate supplemented ewes. Although there was no significant difference between supplemented and grazing ewes on pre-weaning growth rate of their lambs yet lambs born to non-supplemented ewes had lower total live weight gain. It is recommended that feed supplementation and range improvement programs are needed as water harvesting and reseeding of range lands to reduce stress of long journies searching for water and forage, to improve productive performance of sheep and pre-weaning growth of their lambs.

APPRAISAL OF SOIL PROPERTIES OF SOLANUM MELONGENA L. TO DIFFERENT GROWTH CONDITIONS

The response of brinjal plants to organic fertilizers and inorganic fertilizers under pot experiment investigated. This invivo experiment did in the Genetics and Plant Breeding Division of the Department of Botany, University of Calicut. Brinjal plants treated with three sources of organic fertilizers (vermicompost, groundnut cake and bonemeal), three sources of inorganic fertilizers (NPK 16:16:16, NPK 10:5:20 and urea) compared with control. The experimental design followed was a Randomized Complete Block Design (RCBD) with twenty-ve replicates. Soil properties were analyzed by collecting the soil from nine representative samples from each treatment. The soil parameters such as the pH, electrical conductivity (mhos/cm), total organic carbon (%), total organic matter, total nitrogen, phosphorus (kg/ha), potassium (g/ha), manganese, sulphur, iron, zinc, copper and boron were analyzed. The results showed that the macro and micronutrient availability increased in organic fertilizer treatments. Vermicompost increased soil properties signicantly. The percentage of organic carbon increased in organic fertilizer treatments. The same result showed in the case of total organic matter. Groundnut cake treatment gave the highest organic matter (4.75). Total nitrogen was highest in bonemeal (0.95) and potassium was highest in vermicompost (330kg/ha). Phosphorous (48.33kg/ha) and sulphur (43.1mg kg-1) were recorded highest in bonemeal. The highest values of trace elements (25 mg kg-1for Fe in groundnut cake; 0.96mg kg-1Cu, 14mg kg-1 Mn, 5.1mg kg-1 Zn and 0.98 mg kg-1 B in vermicompost observed. Therefore, 38% of the increase in iron, 17.0% off copper,14.75% increase in manganese, 2.82% increase in zinc and 20.99% increase seen in boron.

Health Status of Broiler Chickens Fed Diets with Equi-Protein Replacement of Soybean Meal with Groundunt Cake

This study was carried out to investigate the effect of equi-protein replacement of soybean meal with groundnut cake on immune status, haematology and serum biochemical parameters of broiler chickens. A total of One hundred and twenty (120) Cobb‘s day old chicks were randomly allocated to five (5) dietary treatments of three (3) replicates and eight (8) chicks per replicate in a completely randomized design. The Diet I was the control diet with 100% SBM as the major plant protein source while in other diets, SBM was replaced with 25, 50, 75 and 100% GNC in equi-protein basis and designated as Diets II, III, IV and V respectively. Feed and water were provided ad-libitum throughout the experimental period of 56 days. Newcastle disease (ND) vaccines were administered following a stipulated regime. At the end of the experiment two birds were randomly selected from each replicate and slaughtered. Blood and serum was collected for haematological analysis, serum bioassay and HA/HI tests to determine antibody titres against ND vaccines. All data collected were subjected to one-way analysis of variance using SPSS software package. Results showed that haematological parameters were significantly influenced by the dietary treatments in which birds fed 50% equi-protein replacement of SBM with GNC had better PCV, basophil, MCH and MCHC values compared to that of birds in the other dietary treatments. The antibody titres of experimental birds were not significantly different among treatment groups. The diet with 50% equi-protein replacement of SBM with GNC elicited the highest antibody titres of Log28 and Log210 after the 1st and 2nd ND vaccinations when compared to the other diets. The serum total protein, globulin, albumin, and glucose were significantly influenced by the dietary treatments. The present result indicate that 50% equi-protein replacement of SBM with GNC in diets is not detrimental to health status of broiler chickens.

Comparative evaluation of effects of different sources of groundnut meals on digestibility, growth performance and economics of production of growing rabbits

Three groundnut meals namely: groundnut cake (GNC), locally processed groundnut cake (kulikuli) and toasted groundnut seed(kernel) meal (TGSM) were incorporated in rabbit diets at two levels to generate six diets: 18% GNC, 22% GNC, 18% Kulikuli, 22% Kulikuli, 18% TGSM and 22% TGSM respectively, and 18% GNC also served as the control diet. Twenty four (24) six weeks-old growing rabbits of mixed breeds and sexes with mean initial weight of 568.75±l2.85g were randomly allocated to the six dietary treatment groups, such that each had four rabbits and each rabbit formed a replicate in a completely randomized design laid out in a 2X3 factorial arrangement and fed ad libitum, for 70 days. The main effects showed that while the treatment groups fed TGSM were significantly depressed (p<0.05). rabbits fed GNC and kulikuli were not significantly different (p>0.05) for average daily feed intake, daily body weight gain and final body weight. Feed conversion ratio (FCR) was not significantly (p >0.05) affected among treatment groups. Rabbits fed TGSM had significantly (p<0.05) better apparent digestibility coefficient (78.04%) than those on kulikuli (75.81%6) and the group on kulikuli were better than animals fed GNC (72.09%) for fat digestibility. Fibre digestibility was also significantly different (p <0.05), with rabbits fed kulikuli having the poorest fibre digestion (15.63 %). Crude protein, dry matter and NFE apparent digestibility coefficients were not significantly (p >0.05) affected. Among all the parameters measured, only fat and fibre digestibility coefficients had significant (p <0.05) interactions and NFE digestibility was significantly affected (p <0.05) by level of inclusion, with groups fed 22% digesting it better. Feed cost kg gain did not differ significantly (p >0.05) among the treatment groups. Growth was still on the rise and there was a significantly (P<0.01) strong relationship (correlation and regression) between feed intake and weight gain for all the treatment groups. was concluded that both kulikuli and TGSM are potential feed resources for rabbits, more available to house hold farmers, equally economical as GNC and better still if groundnut farmers and or processors of kulikuli raise rabbits, though TGSM had less value for growth rate compared to GNC and Kulikuli at these levels of inclusion

STUDIES ON PROTEIN REQUIREMENTS OF STEERS

Comparative studies lasting between 59 - 63 days were carried out using the N-balance method to investigate the effect of groundnut cake supplementation on N-metabolism and digestible crude protein (DCP)requirements of three breeds of steers maintained on all-roughage rations of hay and fresh dry of Cynodon rulenfuensis var robustus The results indicated that N intake (/day) Increased ed appreciably with supplementation. The percentage Increases li the intake were 16.4.40.0 and 18.0 for the White Fulani, crossbred and German Brown Steer respectively. Apparent digestibility coefficients for N also increased by 10%0.6.8% and 7.1% for these steers respectively. Faucal nitrogen output (/day) Increased slightly with supplementation with all breedy of steen, while urinary nitrogen loss decreased with the White Fulani, increased with the German Brown and showed no difference with the crossbreed. Absorbed nitrogen (g/day), N-balance (g/day) und N-retention (%) all increased with supplementations Mean values for both metabolic f al ultrogen (MEN) (N/kgDM consumed und endogenous urinary nitrogen (EUN) (/day/wkg 0.75) decreased with supplementation while the mean Hological value (BV) (197) Increased. The values were 2.4 6N/kg DM consumed, 0.11/dm/wg 0.75 and 75.87 respectively. Digestible crude protein requirements (DCP) decreed with supplementation in all the breeds of steen. The values were 1.06, 0.38 and 0.81 (0.75 + 0.20)/day/wkg 0.75) by the N-balance methods and 1.08, 0.51 und 1.20 (0.93 = 0.21) 2DCP/day/wkg 0.75 by the Nuctoriul methody. The DCP requirements therefore range from 0.75 - 0.93 /day/weg 0.75 for these breeds of steers, While there were decreases of approximately 13.14%. 1.99 and 6.4% In the mean DM Intake.

Performance And Serum Metabolites Of Grower Pigs Fed Groundnut Cake, Extruded Soyabean Meal And Cottonseed Cake-Based Diets

The study assessed the effect on performance and serum metabolites of ninety grower pigs fed extruded full-fat soyabean meal (ESBM) and cottonseed cake (CSC) as partial (-50%) and whole (100%) replacement for groundnut cake (GNC) in practical-type diets over 12 weeks feeding period. Ninety Large White X Landrace pigs average initial live weight of 30.50+1.4kg were randomly assigned to five dietary treatments and each treatment had three replicates The diets were iso-nitrogenous and iso-caloric. The ESBM in the diets showed an improvement in average daily weight gain and eed conversion. Diet in which there was 50%replacement of GNC with ESBM gave the best result (P<0.05). However, general trend showed a numerical increase with levels of ESBM and CSC in the diets. Serum albumin and cholesterol levels were significantly (P<0.05) reduced by inclusion of extruded full-fat soyabean meal, and CSC while serum creatinine level was increased.

The Effects Of Replacing Groundnut Cake With Cottonseed Cake On The Performance And Carcass Characteristics Of Broiler Chickens

The effects of replacing groundnut cake(GNC) with cottonseed cake (CSC) at 0, 50 and 100% levels in starter and finisher diets on broiler performance, carcass characteristics and gut morphology were evaluated in a 56 - day feeding trial. Average daily feed intake, average daily weight gain, and feed/gain ratio were significantly (P< 0.05) affected by dietary treatments at the starter and finisher phases. Eviscerated weight (E. W) dressing percentage, total edible meat and abdominal fat pad decreased with increasing level of CSC while weights and lenghts of small intestine, large intestine, caeca and gizzard weight increased significantly (P<0.05) from 0 to 100% CSC diets. It can be concluded that CSC inclusion at 50 and 100% level had adverse effect on the performance and carcass parameters assessed.
