In a bid to decrease cost of production and increase performance in poultry, the study aimed at determining the growth performance and haematological characteristics of pullet chicken fed different feed forms supplemented with or without oyster mushroom (OM), three hundred and twenty (320) day old Harco Black pullet chicks were brooded for five weeks before they were allocated based on weight equalization on the basis of feed forms (mash and pellet) and OM supplementation (without and with 1g of OM per kg of feed) into four (4) treatments for an experiment which lasted for eleven weeks. Each treatment consisting of 80 birds was replicated eight (8) times with ten (10) birds per replicate. Data collected were arranged in a 2 × 2 factorial layout and subjected to Analysis of Variance in a Completely Randomized Design. Final weight, average weight gain and average feed intake in the grower phase were significantly (p<0.05) higher (1244.69g, 11.13g and 106.11 g) in birds given pelletized feed and lower (1146.25g, 9.27g and 105.08 g) in birds fed mash. Also, PCV, WBC, and Hb obtained in the starter phase were significantly (p<0.05) higher (30. 00%, 2.70 x 10 /l and 10.10 g/dl, respectively) in pullet chicken fed diet supplemented with oyster mushroom than those (26.75%, 2.12 x 10 /l and 8.85 g/dl, respectively) recorded by birds fed diets without oyster mushroom. Therefore, improved weight gain, feed conversion ratio, and immunity can be achieved by feeding pullet chickens with pelletized feed supplemented with oyster mushroom.     Dans le but de diminuer les coûts de production et d'augmenter les performances des volailles, l'étude visait à déterminer les performances de croissance et les caractéristiques hématologiques de poulettes nourries de différentes formes d'aliments supplémentées avec ou sans pleurotes (MO), trois cent vingt (320) jours de vieux poussins de poulettes Harco Black ont été couvés pendant cinq semaines avant d'être répartis sur la base d'une égalisation de poids sur la base des formes d'aliments (purée et granule) et d'une supplémentation en MO (sans et avec 1 g de MO par kg d'aliment) en quatre (4) traitements pour une expérience qui a duré onze semaines. Chaque traitement composé de 80 oiseaux a été répliqué huit (8) fois avec dix (10) oiseaux par répliquant. Les données recueillies ont été organisées selon une disposition factorielle 2 × 2 et soumises à une analyse de la variance dans un plan complètement randomisé. Le poids final, le gain de poids moyen et la prisealimentaire moyenne pendant la phase de croissance étaient significativement (p<0,05) plus élevés (1244,69 g, 11,13 g et 106,11 g) chez les oiseaux ayant reçu des aliments granulés et inférieurs (1146,25 g, 9,27 g et 105,08 g) chez les oiseaux. oiseaux nourris de purée. De plus, les PCV, GB et Hb obtenus lors de la phase de démarrage étaient significativement (p<0,05) plus élevés (30,00 %, 2,70 x 109/l et 10,10 g/dl, respectivement) dans le régime alimentaire des poulettes supplémentées en pleurotes que ceux (26,75 %, 2,12 x 109/l et 8,85 g/dl, respectivement) enregistrés par des oiseaux nourris avec des régimes sans pleurotes. Par conséquent, une amélioration du gain de poids, du taux de conversion alimentaire et de l'immunité peut être obtenue en nourrissant des poulettes avec des aliments granulés complétés aux pleurotes.

The potentials of non-conventional resources are great as they play an important role inalleviating the problem of cost and competition of conventional feed sources for livestock and poultry in Nigeria. This study aimed at investigating the growth performance of weaner rabbits fed graded levels of plantain leaf (PL). Thirty mixed bred rabbits aged 6-8 weeks old with an average weight of 0.70 ± 0.02 kg were randomly allotted to five experimental treatments of three replicates each in a completely randomized design. Treatments consisted of T1 – concentrate alone (control), T2 – T5 had 25g, 50g, 75g and 100g of PL respectively. Proximate composition of the feed were carried out while initial weight, final weight, feed intake, feed conversion and weight gain were measured. Results revealed that the crude protein and crude fibre contents of the concentrate and PL recorded 19.30% and 9.97% vs 0.98% and 8.11% respectively. Initially weight ranged from 0.65kg – 0.76kg. Rabbits on T2 recorded the least final weight (0.98kg) which was similar to those on T4 (1.05kg) and T3 (1.10kg) but lower (P<0.05) than those on T5 and T1 (1.32kg and 1.38kg respectively). Rabbits on T5 recorded the highest intake of PL (83.72g/d) while those on T2 had the least (21.04g/d). Weight gain was highest (0.68kg), for rabbits on T1 but least for those on T2 (0.23 kg). The feed conversion ratio ranged from 4.65 (T1) to 14.85 (T4). Rabbits were able to tolerate the plantain leaf meal up to 100g. In addition, rabbits on 100g/day plantain leaf performed comparably with those on control.

The growth performance and blood profile of forty-eight (48), six (6) weeks old rabbit bucks of cross (Chinchilla and New Zealand White) were assessed for 10 weeks. The bucks were allotted on weight equalization basis in a 2 x 4 factorial experimental layout composed of 24 rabbits into steel hutches and wooden hutches each and on four (4) varying levels (0, 5, 10 and 15 mL/litre of water, respectively) of oyster mushroom (Pleurotus ostreatus Jacq ex fr.) extract. Six (6) bucks were assigned to each treatment group and replicated three times with two (2) bucks per replicate in a Completely Randomized Design. The phytochemicals of the oyster mushroom extract showed that 9,12-Octadecadienoic acid (Z, Z)- methyl ester was the most abundant. Results showed that the feed conversion ratio was significantly (P<0.05) best (6.08) in bucks reared in wooden cage and administered 15 mL oyster mushroom extract. Significantly (P<0.05) highest triglycerides (81.00 mg/dL) was obtained in bucks on steel hutch and on 5 mL oyster mushroom extract and lowest (55.00 mg/dL) in bucks on steel hutch and on 10 mL oyster mushroom extract. The lowest (P<0.05) lymphocytes (59.00%) were recorded in bucks on wooden cage and administered 10 mL oyster mushroom extract. It was concluded that oyster mushroom extract up to 15 mL/litre of water administered in either steel hutch or wooden hutch did not impair the growth performance and blood profile of rabbit bucks.

A total of two-hundred-and-forty day old broiler chicks were used to study the response of broiler birds to diets containing graded levels of tiger nut residue (TNR) as a replacement for maize. The diets consisted of 0, 10, 20 and 30% of TNR as a replacement for maize as T1 (control), T2, T3 and T4 respectively. The birds were allotted to four dietary treatments of 4 replicates each containing 60 and 15 birds respectively in a completely randomized design. The data obtained from the experiment were subjected to one - way analysis of variance. The results showed that average weight gain (AWG) and final weight gain (FWG) were high for birds fed 10% TNR and increased numerically than the 0, 20 and 30% groups at the starter phase. In the finisher phase the average weight gain (AWG) and final weight gain (FWG) followed the same trend. Feed intake was not significantly affected by the diet at the starter and finisher phases. In the starter phase the T1 (control) recorded the best and the lowest feed conversion ratio but in the finisher phase, the best feed conversion ratio was observed in T2. The TNR inclusion had no significant (p˃0.05) effect on live weight, dressed weight, dressing percentage, cut-parts and organs of the birds. The haematological parameters were not significantly (p˃0.05) affected by the diets. All the biochemical parameters determined; serum protein, albumin, globulin, urea, creatinine, ALT, AST, cholesterol and triglyceride were not significantly (p˃0.05) affected by the treatment diet. It was concluded that tiger nut residue (TNR) as a replacement for maize at a 30% level of inclusion did not cause any deleterious effects on the performance, carcass and blood profiles of broilers

Aim of study: To evaluate the effects of increasing NaCl levels on the zootechnical performance of pacu fingerling. Area of study: The experiments were conducted at the Aquatic Organism Production and Reproduction Systems Laboratory belonging to the Federal University of Paraná (UFPR), in the Palotina Sector, Paraná Estate, Brazil. Material and methods: Seven hundred and fifty fingerlings with an average weight of 3.41 ± 0.09 g were distributed in circular boxes, in a completely randomized design consisting of six treatments and five replications. Treatments comprised soybean- and maize-based diets containing increasing levels of NaCl (0.00, 0.25, 0.50, 0.75, 1.00 and 1.25%). The experiments were conducted for 50 days. At the end of the experimental period the fish were fasted for 24 hours, anesthetized, weighed and measured to calculate zootechnical performances. Performance data were subjected to an analysis of variance followed by Tukey’s test when significant differences were found between the means (p<0.05). Main results: The influence (p<0.05) of dietary NaCl levels on final weight, feed intake, apparent feed conversion, specific growth rate, average weight gain, clean trunk production, head carcass yield, headless carcass yield, feed intake and survival was assessed. The results indicate that non-salt treated fingerlings along with the 0.25% salt inclusion treatment led to better feed use, as evidenced by apparent feed conversions of 1.64 and 2.02, respectively. Research highlights: The inclusion of NaCl in pacu fingerling soybean and maize-based diets is not recommended.

The purposes of determining the influence of the light and sexing on growth performance and slaughter results atyoung quails from Balotesti population, was organized an experiment on 150 quails, betwen age of 28 and 70 days. The chicks were divided into two groups (control and experimental), and growth and slaughter performance were determined separately by sex. Have studied 2 lighting programs, a program of continous lighting with photoperiod duration of 16 hours (16 L + 8 N, control group) and a program with lighting with asymetric hours intervals with photoperiod duration of 16 hours (10L+2N+6L+6N, experimental group).Males and females from the experimental group were recorded average performance of growth high during the period 28 - 70 days. Live weight at age of 70 days was higher with 7.54 %, average weight gain was higher with 14.86 % and feed conversion rate was lower with 13.51 % at males from experimental group compared to males from the control group. Also, the live weight at the age of 70 days was higher with 18.09 %; average weight gain was higher with 35.12 %, while feed conversion rate was reduced with 30.08 % on females from the experimental group compared to females from the control group.The results of the slaughter at 70 days were superior in the caseof females from the both groups versus males. The average weight of the carcase was higher with 17.53 % in case of the females than that of males from the experimental group, and the carcase yield was 65.37 % at the females and 65.56 % for males. Also, the average weight of the carcase was higher with 5.08 % in case of females compared to that males from the control group, and the carcase yield was 64.20 % to females 66.70 % on males.Superior results recorded in the case of females and males from the experimental group recommended the program of lighting with asymmetric hours intervals in the growth of youth quail. Also, the higher slaughter results recorded in the case of females of the two groups recommended them in the meat production through a broiler of quail that combine advantages in the production of both males and females.

A 56 –day study was conducted to determine the growth performance and nutrient utilization of broiler chickens fed with two varieties (white and yellow) of cassava grit based diets. A total of 240 one day- old unsexed Arbor acre broiler chicks were assigned to eighty dietary treatments in a 2 x 4 factorial arrangement using completely randomized design. Diets were formulated to include two varieties of cassava, TME 419 (white) and TMS 01 1368 (yellow) at four inclusion levels (0, 25, 50 and 75%). Each treatment consisted of 30 birds and three replicates of 10 birds each. Data was collected on growth performance and nutrient digestibility at the end of the starter (4th week) and finisher (8th week) phases. At the starter phase, birds fed 50% white cassava grits diet had the highest (P < 0.05) final weight and weight gain (730.00 and 693.67g/bird). At the finisher phase, birds fed 50% yellow cassava grits diet had the highest (P < 0.05) final weight and weight gain (2235.60 and 1454.00g/bird), respectively while the least final weight and weight gain values (2008.80 and 1267.80g/birds) were obtained in birds fed the control diet. At the starter phase, birds fed 75% white cassava grits diet had the best (P < 0.05) feed conversion ratio of 2.18, while birds fed 25% yellow cassava grits diet as well as those fed the control diet had the least (P < 0.05) feed conversion ratio of 2.62 and 2.51 respectively. Birds fed 50% yellow as well as those fed 75% yellow cassava grits diets had the highest dry matter and crude fibre digestibility at the starter and finisher phases, respectively. In conclusion the substitution of maize with white cassava grits up to 50% level improved growth performance at the starter phase. However, either white or yellow cassava can be substituted for maize up to 75 % at the finishing phase.

This paper aimed to evaluate the metabolizability, performance and economic viability of purified glycerin inclusion in balanced diets fed to chicken broilers from 8 to 21 days old. Two experiments were conducted. In the first experiment, 100 broilers (14 days old) were distributed in a completely randomized design into two treatments, with five replications of 10 broilers. Treatments consisted of a control diet and a test diet, in which purified glycerin replaced 10% of the control diet. In the second experiment, 200 broilers (8 days old) were distributed in a completely randomized design into four treatments (0, 2, 4 and 6% of purified glycerin inclusion), with five replications of 10 broilers. The weight gain, feed intake, feed conversion, final weight, apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), metabolizability coefficients of dry matter (DMMC), crude protein (CPMC) and gross energy (GEMC), and the cost of feed per kg of broiler produced were evaluated. The AME, AMEn, DMMC, CPMC and GEMC from the purified glycerin were 3790 and 3560 kcal/kg, and 83.72, 71.52 and 86.27%, respectively. The glycerin levels did not affect (p>0.05) any of the performance characteristics (weight gain, feed intake, feed conversion and final weight). The lowest feeding cost and the highest gross margin were obtained for broilers fed with 6% purified glycerin. The inclusion of 6% purified glycerin in balanced diets for broilers from 8 to 21 days old was technically and economically feasible.

This study aimed to evaluate the use of acacia tannin as a toxic metal adsorbent in the diets of broilers fed with the inclusion of golden mussel meal in substitution for calcitic limestone. In the first trial, 648 male 21-day-old animals were divided among six treatments and six replicates, with 18 birds per experimental unit, organized in a completely randomized design (DIC). The treatments were diets with different acacia tannin levels (0, 250, 500, 750, 1000, or 1250 g ton-1). The results indicated that 250 g ton-1 of tannin was not harmful to weight gain, final weight, or feed conversion. Tannin levels caused a decrease in carcass yield and fat deposition and an increase in liver size. For the second trial, 900 male broilers of 21 days of age were used and distributed in a DIC, with different levels of substitution of calcitic limestone by the golden mussel meal (0, 25, 50, 75, or 100 %) and supplementation or not with acacia tannins (250 g ton-1), with 5 replicates and each experimental unit being composed of 18 birds. The performance data show that the use of 250 g ton-1 of tannin is detrimental to bone performance and resistance and golden mussel meal can be used to substitute up to 100 % of the limestone in the diets without affecting the variables studied.

A 28-day feeding trial was conducted to evaluate the effect of dietary inclusion of Anth:-:: macrophylla meal on the performance of broiler starter chicks. Anthonala macrophyla was harvested from the wild, wushed, chopped into tablets, sun-dried and milled to produce the test meal. The meal contained un diy matter basis 21.11% crude protein, 1.90% crude fat, 2.00% total ash, 5.03% crude fibre and 54.36% nitrogen free extract. Five (5) broiler starter diets were formulated to contain the meal at 0,5,10,15 and 20% level, respectively. One hundred and eighty (180) day-old Anak broiler chicks were divided into 5 groups of thirty-six birds each and randomly allocated to the five treatment rations in a completely randomized design (CRD). Data were collected on feed intake, weight gain, feed conversion ratio, protein efficient ratio, cost of production of one kilogramme of each test feed among others and carcass characteristics. At 15 and 20% dietary levels. Anthonata macrophylla significantly (p<0.05) depressed feed intake, daily weight guin, feed conversion and protein efficiency ratios and final weight gain of the birds. Organ weight parameters showed no significant (P>0.05) differences among the treatments. The results of this investigation suggest that Anthonata macrophyla meal can be included in broiler starter ration up to 10% without any deleterious effect on the birds and at this level of inclusion, feed cost was reduced by 10%.

A study conducted for a period of fifty (50) days to determine the growth performance, carcass and organ weight of growing boars fed graded dietary levels of raw Icacinia manni tuber meal. Four experimental diets were formulated with Icacinia manni (Earth ball) replacing maize at 0, 5, 10 and 15% levels designated as T1(control), T2, T3 and T4, respectively. Forty-eight (48) young boars (Landrace x Large white) each weighed 7.72+ 0.35kg were assigned to the four dietary treatments and replicated three times of four boars each in a completely randomized design. Carcass traits and relative organs weights were evaluated. These traits were; dressed weight, dressing percentage, head, shank, trotter, belly, thick rib chop, rib chop, loin, chump chop, leg fillet end, Leg shank end, liver, lungs, kidney spleen and heart. The results indicated that apart from T4, diets T1, T2 and T3 did not differ significantly (P>0.05) in terms of feed intake, weight gain and feed conversion ratio. This implies that Icacinia manni did not affect growth performance except at 15% level of inclusion Similarly, Pigs fed diets T2 and T3 showed significant (P<0.05) increase in dressed weight, dressing percentage as well as certain primal cuts such as breast, rib chop, loin and chump chop. However, relative organs weight did not differ (P>0.05) across dietary treatments except the lungs in T4 (15%) signifying the non-deleterious effect of raw icacinia manni, at 10%. To attain optimum performance and carcass characteristics in young boars therefore, inclusion of raw Icacinia manni in young boars’ diet at 10 percent is recommended.
