  This study discussed challenges of Greed and Corruption in agricultural extension development and practice in Nigeria. Corruption is a social-human factor that encompasses unilateral abuses by government officials such as embezzlement and nepotism as well as abuses linking public and private actors such as bribery, extortion, influence, peddling or fraud. The study looked at paradigm and dimensions of corruption; emerging trends in agricultural extension practice in Nigeria; challenges of corruption to agricultural extension development and practice as well as institutionalizing anti-corruption measures. Central to the discussions on these is that corruption poses a serious development challenge in many spheres of human endeavour including agricultural development. The study noted that to effectively control corruption in Nigeria ethical standards in decision-making must be the national policy on corruption. It is suggested among others that any effort aimed at improving agricultural extension development and practice in Nigeria would require an articulated and functional policy on agricultural extension.

  Adaptation of the local chickens in Nigeria to the different agro-ecological zones has produced ecotypes that can be conveniently classified on the basis of body weight and size into two viz; Heavy Ecotype (HE) and Light Ecotype (LE). These distinct types may differ in their egg production characteristics. Short-term egg production and egg quality characteristics of HE and LE and their F1 crosses (HExLE and LExHE) were studied. The objective of the study was to evaluate the short-term egg production and quality traits of the HE, LE and their F1 reciprocal crosses. Data on percent hen-day production, egg number per hen, egg weight and egg mass of 50 pullets each of HE, LE, HEXLE and LEXHE were collected. Also, external and internal egg quality traits were assessed on a total of 640 eggs. Data were subjected to ANOVA technique. Result showed that there was no significant (p>0.05) genetic group effect on short-term percent hen-day production, egg number and egg mass. However, genetic group significantly affected egg weight (p<0.05). Genetic group effect was significant (p<0.01) in all the egg quality traits studied except shell weight. The crossbred groups demonstrated heterotic effects in egg width and egg shape index but their performances in the other egg quality traits remained intermediate between the two parents. On the basis of short-term egg production the HE and LE may not be considered as distinct strains. Egg quality traits obtained are comparable with most exotic breeds thus demonstrating high egg quality traits of the local chickens of Nigeria.

  Two experiments were carried out to investigate the effect of roasted Pigeonpea Seed Meal (PSM) on growth performance of broiler birds. Two hundred and forty day-old commercial unsexed broiler chicks (Anak strain) were used in experiment 1, while 168 four-week old broiler birds from experiment 1 were used in experiment 2. Birds in experiments 1 and 2 were divided into 6 groups. Experiment 1 birds were randomly assigned to six isoenergetic and isonitrogenous broiler starter diets containing 0, 6.5, 13.0, 19.5, 26.0 and 32.5% roasted PSM. Experiment 2 birds were also randomly assigned to 6 isoenergetic and isonitrogenous broiler finisher diets containing 0, 5.5, 10.5, 16.0, 21.5 and 27.0% roasted PSM. Parameters considered were weight gain, feed intake, feed conversion ratio, protein efficiency ratio, dressed carcass weight and carcass dressing percent. Results (Experiment 1) showed that there were significant differences (p<0.05) among treatments in average daily weight gain, average daily feed intake and feed conversion ratio. Feed intake, weight gain and efficiency of feed utilization declined at the 32.5% level of roasted PSM inclusion. However, there were no significant differences (p>0.05) among treatments in all the parameters considered in experiment 2. The results showed conclusively that roasted PSM can be included in broiler starter and finisher diets at 26% and 27% levels, respectively without any adverse effect on broiler birds.

  A total of fifty-two Golden-sex link (brown) hens in their 65th week of lay were used in a study conducted to determine the oviposition time and interval, total egg production, clutch length and number of pause days of the birds under the humid tropical environment. The hens were also divided into four classes on the basis of their laying performances as follows: good layers, intermediate layers, poor layers and non layers and their physical conditions appraised. The birds were supplied water ad libitum and fed layers mash containing 16.5% crude protein and 9.62 MJ/kg ME for 5 weeks. Results showed that the peak of lay was between 7.30-8.30 am and declined gradually until only one egg was laid between 3.30-4.30 pm. About 66.36% and 33.64% of the eggs were laid in the morning hours and in the afternoon hours, respectively. The mean oviposition interval was 26.61 h, while the average laying intensity was 48.90%. About 98% of the clutch lengths were of 5 cycle lengths and below, with the highest frequency of occurrence being 1 cycle length. The total number of pause days over all birds was 558 days. Hens with the longest clutches and shortest number of pause days produced the greatest number of eggs. Observation made on the physical characteristics revealed that good layers had smooth and waxy comb and wattles. The vents were moist and enlarged with flexible pubic bone, soft abdomen and worn out feathers. Intermediate layers had similar features with the good layers except that eye rings, beaks and shanks were slightly bleached. Poor layers had dry combs and wattles; tight and hard abdomen and closed pubic bones. Non layers had scaly, dry and rough comb and wattles; dull eyes and rigid pubic bones which were relatively close together.

  Background and Objective: The European Union banned the use of antibiotics for non-therapeutic purposes because of the possibility of the transfer of antibiotic resistance to pathogenic bacteria in humans. It is therefore imperative to find safe alternatives to the use of antibiotics. The aim of this study was to determine the effects of the dietary inclusion of yeast (Saccharomyces cerevisiae) on hematological and biochemical indices of West African dwarf sheep. Materials and Methods: A total of twenty four (24) lambs (12 males and 12 females) with an average weight of 10.30 kg were randomly allotted to six treatment diets in a 3×2 factorial arrangement involving grass (Panicum maximum) hay, grass-legume mixture (50:50) hay and legume (Centrosema pubescens) hay, as well as with two yeast levels (0 and 1.5 g per kg of basal diet). The six diets were abbreviated as G0, G1.5, G/L0, G/L1.5, L0 and L1.5 (G: grass, L: Legume, G/L: Grass/legume (50:50) mixture, 0: 0 g of S. cerevisiae per kg of diet and 1.5:1.5 g of S. cerevisiae per kg of diet). Results: The results showed that the packed cell volume, hemoglobin concentration and white blood cell count were significantly (p<0.05) higher for sheep fed a legume diet supplemented with S. cerevisiae compared to that for sheep fed other diets. Sheep fed the grass and legume mixture and the legume diets supplemented with S. cerevisiae had significantly (p<0.05) higher albumin values than those of sheep fed other diets. Sheep fed the legume diet without S. cerevisiae supplementation had the highest calcium values of all sheep diet groups tested. Conclusion: Based on the results obtained, the addition of 1.5g of S. cerevisiae per kg of legume diet is recommended.

  Background and Objective: In order to reduce high cost of feed which will step-down the cost of poultry products and encourage small scale and medium scale poultry production, efforts must be made by animal nutritionists to exploit and use some unconventional feed ingredients. Most of these unconventional feed ingredients such as brewer’s dried grain pose some threats (high fiber) with regards to their utilization by birds. Hence, the use of feed enzymes to reduce these threats for optimum productivity becomes necessary. The aim of the study was to determine the effect of different levels of enzyme fortified dried brewer’s grain (EDBG) on blood bio-markers, growth performance, carcass traits; and income over feed cost in a five week trial. Materials and Methods: A total of 300 day old non-sexed “Anak strain” chicks were randomly assigned to four dietary treatments with five replicates of 15 birds each. The treatments include, EDBG0, EDBG3, EDBG6 and EDBG9 for 0, 3, 6 and 9% levels of EDBG for both starter and finisher phases. Results: Growth traits for starter phase was better (p<0.05) for birds fed control (EDBG0) diet while birds fed EDBG3 recorded an improved (p<0.05) growth traits during the finisher phase of the feeding trial. Carcass yield, thigh, breast and drumstick weights of birds had the highest (p<0.05) values for birds fed EDBG3, while birds fed EDBG9 recorded the lowest (p<0.05) carcass, thigh, breast and drumstick weights. The blood bio-marker examination differ (p<0.05) among treatments for Eosinophil, Monocyte, Lymphocyte, White blood cell, Hemoglobin and Red blood cell. Hemoglobin concentration and RBC was highest (p<0.05) for birds fed EDBG0 and EDBG3. Birds fed EDBG3 recorded the highest (p<0.05) revenue from a bird produced and a better income over feed cost. Although, cost of total feed consumed was the highest for birds fed EDBG0 and EDBG3 but similar to those fed EDBG6. Conclusion: With regards to improved growth traits, improved cut yields and a better production cost as well as stable health status of broilers, 3% level of Enzyme fortified dried brewer's grain can be used safely.
