Monodora Myristica

A research work was carried out to evaluate the effects of toasted Monodora myristica spice as feed additive in quail diet in a completely randomized design. The proximate, vitamin and mineral composition and anti-nutritional factors, growth performance, cut parts and organ characteristics, biochemical parameters and egg quality traits were evaluated in this study that lasted for fifteen weeks. A total of 120 day-old quail chicks were brooded for 14 days. Thereafter, they were allocated to four dietary treatments designated D1, D2, D3 and D4 also having 0, 0.5, 1.0 and 1.5% Monodora myristica respectively. Each treatment was replicated three times at 10 quails (2 males: 8 females) per replicate. Growth performance and carcass characteristics study lasted for 7 weeks while eggs were collected for four weeks. Daily feed intake was reported to be 2.39g/bird/day, 2.83g/bird/day, 3.22g/bird/day and 3.15g/bird/day respectively for 0, 0.5, 1.0 and 1.5% Monodora myristica-flavoured diets. There was no significant (P>0.05) increase in the daily feed intake though it increased only numerically as level of inclusion increased from 0% to 1.0% but decreased at the level above 1.0%. There were significant (P<0.05) differences in the average daily weight gain and feed conversion ratio among the varying treatments. Average daily weight gains for the groups were 1.68g/b/d, 2.18g/b/d, 3.35g/b/d and 3.37g/b/d respectively for D1, D2, D3 and D4. Significant (P<0.05) differences were observed in the cut parts and organ characteristics. From the results, Monodora myristica was not observed to be detrimental to the quails with respect to the weight of organs and cut parts. Dressed weight increased as level of inclusion increased up to 1.0% but then declined afterwards to 137.69g. Liver weights were 3.55%, 2.55%, 1.79% and 1.77% respectively for D1, D2, D3 and D4. Quails fed the control diet recorded the highest liver weight (P<0.05) of 3.55% indicating stress condition. The low liver weight in quails fed Monodora-flavoured diet indicates potential of Monodora to protect the liver from free radicals that cause stress. Breast meat was significantly reduced at 1.0% and 1.5% M. myristica inclusion

The effects on growth performance, feed utilization, survival and whole fish body proximate composition of replacing fishmeal (Rastrineobola argentea) with a locally available spirulina species (Arthrospira fusiformis) as a protein ingredient in the feed of Rufiji tilapia (Oreochromis urolepis urolepis) fry was examined. Fishmeal replacement with A. fusiformis was carried out at 5%, 15%, 25%, 35% and 100% (S5, S15, S25, S35 and S100), and the effect of the replacement was compared with the control diet (S0, 0% spirulina). Fish fry were stocked at an average initial weight of 0.57 g at 10 fish per 0.1 m3 and cultured for 60 days using full strength salt water (30-35 ppt). A. fusiformis was isolated from Momela Lake in Arusha National Park, Tanzania and propagated using selected culture media. It was observed that fish fry fed spirulina at a 5% fishmeal substitution level diet had better (p<0.05) final weight (8.48), average daily weight gain (0.132), specific growth rate (4.47), feed conversion rate (2.08) and protein efficiency ratio (1.37) compared to the control fish group. Growth performance in fish fed diet S15 was comparable with the control group (p>0.05). Spirulina supplementation had no effect on fish survival rates and meat quality. It appears that the Momella Lake spirulina may be an appropriate growth-stimulating plant protein when used as a feed additive in Rufiji tilapia mariculture.

Completely Randomized Design

This study was carried out to investigate the growth performance of rabbits fed pawpaw seed based diet. In ten-week trial, 60 mixed breeds of weaner rabbits aged 5 - 6 weeks were allotted to five treatments in a completely randomized design. Five concentrate diets were  compounded with the inclusion of pawpaw seed meal (PSM) at 0, 10, 20, 30 and 40% graded levels. The rabbits were weighed before the commencement of the experiment and  subsequently weekly throughout the experiment to calculate the daily weight gain. The proximate composition and the metabolizable energy of experimental diets were carried out  in the laboratory. The feed intake was estimate from the differences between the feed offer and  the feed refusal. The proximate components of the diets contained inclusion of PSM were similar and comparable to the control diet in this study. The metabolizable energy of 10%PSM, 20%PSM and 40%PSM diets were higher than the 0%PSM. There were no  significant differences (P>0.05) among the means of feed intake, initial and final weight of  rabbits across the experimental treatment. The rabbits fed diets 0%PSM (6.52) and 30%PSM  (6.82) had significantly higher (p<0.05) daily weight gains as compared to 10%PSM (5.82)  and 40%PSM (4.85) diets whereas rabbits fed 20%PSM (4.59) had the best feed conversion  ratio compared to 10%PSM (5.92), 0%PSM (6.55), 30%PSM (6.71) and 40%PSM (7.75). It could therefore be concluded that inclusion of pawpaw seed meal in the diet of rabbits up to 30% improved feed intake and growth performance of rabbits.     Cette étude a été réalisée pour étudier les performances de croissance des lapins nourris à base de graines de papaye. Au cours d'un essai de dix semaines, 60 races mixtes de lapins sevrés âgés de 5 à 6 semaines ont été attribuées à cinq traitements d'une conception complètement randomisée. Cinq régimes concentrés ont été composés avec l'inclusion du repas de graine de papaye (le 'PSM') aux niveaux classés 0, 10, 20, 30 et 40%. Les lapins ont été pesés avant le début de l'expérience et par la suite chaque semaine tout au long de l'expérience pour calculer le gain de poids quotidien. La composition immédiate et l'énergie métabolisable des régimes expérimentaux ont été réalisées en laboratoire. L'apport alimentaire a été estimé à partir des différences entre l'offre alimentaire et le refus d'alimentation. Les composants proximate des régimes qui ont de 'PSM' étaient semblables et comparables au régime de contrôle dans cette étude. L'énergie métabolisable de 10% PSM, 20%PSM et 40%PSM régimes étaient plus élevés que les 0%PSM. Il n'y avait pas de différences significatives (P>0,05) entre les moyens d'apport alimentaire, le poids initial et final des lapins dans le traitement expérimental. Les lapins nourris régimes 0%PSM (6.52) et 30%PSM (6.82) ont eu sensiblement plus haut (p<0.05) gains quotidiens de poids par rapport à 10%PSM (5.82) et 40%PSM (4.85) régime alors que les lapins nourris à 20% PSM (4.59) avaient le meilleur ratio de conversion des aliments contre 10%PSM (5.92), 0%PSM (6.55), 30% PSM (6.71) et 40% PSM (7.75). On pourrait donc conclure que l'inclusion de farine de graines de papaye dans l'alimentation des lapins jusqu'à 30 % a amélioré l'apport alimentaire et les performances de croissance des lapins.

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.

This study was conducted to investigate the effect of dietary copper and probiotic supplementation on growth performance and carcass characteristics of broiler Chickens. A total of 180-day old marshal broiler chicks of mixed sex were randomly allotted to six treatment groups of 30 birds each. The Treatments were divided into three replicates of ten birds each; starter and finisher diets were formulated and fed for a period of fifty-six days. The dietary treatments were subjected to completely randomized design experimental layout which was made up of probiotic (0 and 500ppm) and copper (0, 125 and 250mg).The chicks were fed the broiler starter diet for the first 28 days and broiler finisher for the last 28 days. Treatment effect on broiler body weight, feed intake and feed conversion ratio were determined on a weekly basis. Data obtained were analyzed using analysis of variance (ANOVA) and, Duncan's Multiple Range Test was used to separate significant means. Dietary supplementation of copper and probiotic had no significant (P> 0.05) effect on final weight (FW), daily weight gain (DWG), feed intake (FI), and feed conversion ratio (FCR) at the starter phase of the experiment. However, at finisher phase, inclusion of probiotic resulted in higher significant (P < 0.05) values for FW (2214.12g/b) DWG (60.22g/b/d), FI (159.02g/b/d), and FCR (2.64). The carcass yields of the broilers were significantly (P< 0.05) influenced by copper and probiotic supplementations. However, lower value (1.07%) was obtained for abdominal fat in broilers fed 250mg Cu/kg supplemented diet. The study concluded that supplementation of copper and probiotics resulted in improved growth performance and carcass yield of broiler chickens.

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.

Forty growing rabbits were allocated equally to five groups in a 2 x 3 factorial layout and caged individually for a 56-day trial period in hutches. They were used to compare the effects of two processing methods (unfermented and fermented) and three dietary replacement levels of Pineapple peel meal (PPM) at 0%, 12.5% and 25% of maize on weight for weight basis. Parameters evaluated during the trial period included: growth rate, feed intake, feed conversion ratio and feed cost. Results show that average daily weight gain (ADG) reduced (P<0.05) as dietary inclusion level of PPM increased, although rabbits fed PPM at 12.5% dietary inclusion level compared favourably (P>0.05) with those fed the control diet (0%). However, ADG of rabbits fed fermented PPM was statistically higher (P<0.05) than that recorded for rabbits fed unfermented PPM. No significant (P>0.05) difference was observed in daily feed intake of rabbits as a result of dietary inclusion level or processing type of PPM. Better (P<0.05) feed efficiency was recorded in rabbits fed PPM at 12.5% dietary inclusion level than those fed at 25%. Fermentation enhanced the nutritional value of feedstuff and also improved feed efficiency. Total feed cost reduced (P<0.05) by 21.39% when PPM was included in the diet at 25%. However, production result was not comparable with the control. But feeding fermented PPM at 12.5% inclusion level resulted in the best (P<0.05) economy of production. Processing type or dietary inclusion level of PPM had no significant (P>0.05) effect on dressing-out percentage of experimental animals. There were neither significant (P>0.05) effects of processing type nor dietary inclusion level on retail cuts of the rabbits fed the different experimental diets. In all feeding rabbits with diets containing fermented PPM up to 12.5% replacement level for maize optimum performance.

The effect of dietary treatments on growth performance, haematological and biochemical indices of finisher broilers as well as economics of broiler production were determined in this experiment. Four broiler finisher diets were formulated with different inclusion levels of fermented cassava flour/blood mixture code-named “cassablood”. The control diet (T1) contained 0% cassablood, while diets 2, 3 and 4 contained 20%, 25% and 30%  cassablood respectively. 120 four weeks old Anak broiler chicken were randomly allocated the 4 diets with 30 birds per treatment replicated 3 times with ten 10 broilers per replicate in a completely randomized design (CRD).Treatment effects on final body weight, final weight gain, feed intake and feed conversion ratio were significant (P<0.05). Birds fed cassabloodbased diets compared favourably with the control diet. 20% cassablood inclusion performed equally with the control diet in feed intake, body weight gain and feed conversion ratio. All dietary groups also showed no significant differences (P>0.05) in most haematological and serum biochemical indices of broilers except in cholesterol, glucose and triglyceride contents which differed (P<0.05) significantly Similarly, chicken on 20% and 25% inclusion levels produced significantly (P < 0.05) higher economic gains in terms of feed cost per kilogram of broiler among all the treatments. Therefore, 20 - 25% cassablood dietary inclusion level was recommended in broiler diet for production and profit maximization.

Cecal Microbiota

Probiotics can promote the health and growth performance of animals through modulation of intestinal microbiota. When used as a feed additive, they have the potential to minimize or abolish the use of antibiotics. In this study, we investigated the effect of the probiotic strain Bacillus amyloliquefaciens TL on the growth performance and cecum microflora composition in Cobb 500 broiler chickens. In total, 180 broilers were randomly divided into three groups—each group comprised 4 pens, and each pen contained 15 chickens. The three groups were fed either a control diet, or a diet supplemented with either the antibiotic chlortetracycline or B. amyloliquefaciens TL. Broilers were weighed, and cecum contents were collected on days 7, 14, 21, and 35, respectively. The broilers in both the antibiotic and probiotic groups exhibited significant weight gain compared with controls, exhibiting increases of 16.02% and 13.40%, respectively, after 35 days (P<0.01). Similarly, the feed conversion ratio (FCR, 1–35 days) of broilers in the chlortetracycline and B. amyloliquefaciens TL groups was lower than that of the controls. HiSeq high-throughput sequencing of 16S rRNA of the cecal microbiota was performed on days 7, 14, 21, and 35, respectively. The Firmicutes/Bacteroidetes ratio was higher in the chlortetracycline and B. amyloliquefaciens TL groups than in the control group on days 14, 21, and 35, and especially on day 21. The prevalence of genera Oscillospira, Ruminococcus, Butyricicoccus, and Faecalibacterium (Firmicutes) was higher in the antibiotic and probiotic groups, while that of Bacteroides, Parabacteroides (Bacteroidetes), and Lactobacillus was higher in the control group. In this study, the changes in the microbiota of the probiotic group were similar to those in the antibiotic group. These results suggest that the probiotic strain B. amyloliquefaciens TL can modulate the cecal microbiota of broilers similar to chlortetracycline.

The objective of the current study is to assess the effects of the inclusion of 6-n phytase to a phosphorous-deficient diet on the growth performance (feed intake, average daily gain, and feed conversion ratio), apparent digestibility of calcium and phosphorus, and bone characteristics of grower–finisher pigs. The experimental diets included a phosphorus-deficient diet containing 0 (negative control), 250, 500, 1000, or 1500 FTU/kg of 6-phytase, and a diet formulated to meet the phosphorus nutrient requirements of pigs (positive control). Pigs were fed the experimental diets from the time they were ~35 kg body weight until they reached slaughter weight of ~110 kg. Bone status of the metacarpal (ash, mineral content) and femur (mineralization, geometry, and mechanical strength) bones were assessed. There was no effect of dietary treatment on feed intake. Feed conversion ratio was improved following inclusion of phytase at a dose of 500 FTU/kg or higher. Phytase inclusion at a dose of 1000 FTU/kg increased the average daily weight gain of grower–finisher pigs. Phytase inclusion at a dose of 500 FTU/kg was sufficient to increase metacarpal phosphorus content. Femur mid-diaphysis ash percentage was significantly increased even after the inclusion of the lowest dose of phytase. Analysis of structural parameters of femur mechanical strength (Young’s modulus, yield stress, yield strain, ultimate stress, ultimate strain) showed that the inclusion of a phytase dose of 500 FTU/kg in growing/finishing diets was sufficient to significantly improve bone status of grower–finisher pigs at slaughter.

The objective of the present study was to evaluate the effects of dam and offspring dietary supplementation with a natural feed additive on the growth performance and meat quality parameters of growing rabbits. The growing rabbits are selected from lactating does receiving a control diet (C) or diets supplemented with 0.3% (SP1) and 0.6% (SP2) of feed additive containing brown seaweeds (Laminaria spp.) and plant extracts. In the postweaning phase, the growing rabbits remained in the treatment group defined by their does and the trial lasted 42 days. The average daily feed intake and feed conversion ratio were improved in the rabbit fed 0.6% of the natural feed additive. The cholesterol content tended to be lower in Longissimus lumborum (LL) muscle and decrease in Semimembranosus (SM) muscle (in SP2 −41.36% than controls). The α tocopherol and retinol content were enhanced in both muscles of rabbit fed the natural mixture (SP1 and SP2 groups). An improvement of sensory attributes of texture was observed in both muscles from rabbit fed natural mixture. In conclusion, long term supplementation of both lactating does and offspring with the high dosage of brown seaweed and plant polyphenols improves growth performance and enhances meat nutritional and sensory parameters.
