Abstract The effect of milled canola grain (MCG) in the diet of broiler chickens, from 1 to 42 days old, on performance, organ weight, biochemical profile, and carcass yield was evaluated. A total of 660 one-day-old male Cobb® broilers were distributed in a completely randomized design with six levels of inclusion of MCG in the diet (0; 5; 10; 15; 20, and 25%), totaling six treatments with five replicates of 22 birds. The canola used for the experiment was ground using a hammer mill with a 4.5 mm sieve to obtain a DGM of 955 µm. Performance data, organ index, blood biochemical profile, carcass yields, and cut up weights were evaluated. The data were analyzed by analysis of variance (ANOVA), and when there was significance Dunnett’ test was used to compare the inclusion levels the control diet. An effect was seen on mean weights and on feed conversion based on the inclusion level of MCG in the diets. The birds that received 20 and 25% inclusion of canola in the diet presented a worse performance in relation to that of the control. For the other variables analyzed, no effect of the treatments was observed when compared with the control (p > 0.05). It was concluded that the inclusion level of MCG in the diet of up to 15% can be used without losses to the performance of birds and without influencing the metabolism of the birds.

The effect of a prebiotic mannan oligosaccharides (Actigen™) supplementation for 35 days was analyzed on growth, carcass traits and blood physiology of broilers. A total of 360-day-old broilers distributed under completely randomized design into four treatment groups with 24 replicates of 15 birds each was fed with Actigen™ supplemented diets @ 0.2, 0.4 and 0.6 g/Kg and a control diet. Data for growth performance were collected weekly while slaughtering data at 35th day. Results showed that the birds fed with Actigen™ added diet @ 0.6 g/Kg exhibited improved livability% (98.88±1.11), feed intake (3391.68±38.70 g), body weight (2157.66±31.52 g), weight gain (2111.49±30.89 g), FCR (1.57±0.03), dressing% (72.28±0.40), breast yield% (29.58±0.05), thigh yield% (31.61±0.30) and blood biochemical parameters. Superior (P£0.05) antibody response against ND and IB were recorded in birds exposed to Actigen™ supplemented diet @ 0.6 g/Kg. It was concluded that Actigen™ supplementation @ 0.6 g/Kg corroborated to improve growth, carcass traits, blood biochemistry and antibody response in broilers.

Three hundred 21-day-old broiler chicks were reared using a 3 x 3 factorial model in a completely randomized design with 10 treatment groups having 3 replicates of 10 birds each. The birds were raised on a commercial starter diet at the starter phase before being allotted into dietary groups in a 21-d feeding trial at the finisher phase. The interaction between treatment and varying inclusion levels of processed-fermented Jatropha curcas (L) kernel meals (JKM) on the performance of broiler chicks was investigated. Jatropha curcas kernels were subjected to three different processing methods, namely: raw defatted fermented meal (RDFM), cooked defatted fermented meal (CDFM) and lye treated defatted fermented meal (LDFM). Each meal was included at varying inclusion levels of 2.5%, 5.0% and 7.5% such that diet 1 (control) contained 0% JKM while diets 2, 3, 4 contained 2.5%, 5.0% and 7.5% RDFM, diets 5, 6, and 7 contained 2.5%, 5.0% and 7.5% CDFM and diets 8, 9, 10 contained 2.5%, 5.0% and 7.5% LDFM. Feeding differently processed-fermented JKM to these broilers did not (p>0.05) compromise the feed conversion ratio. The results indicated an improvement (p<0.05) in the weight gain of broiler chicks fed CDFM and LDFM at 2.5 and 5.0% inclusion levels respectively. There were significantly (P<0.05) elevated levels of alkaline phosphatase and creatinine in their blood serum. The kidney, lungs and proventriculus of birds fed CDFM showed significant differences (p<0.05) among the treatments. Therefore, finisher broilers could tolerate up to 5.0% inclusion level of LDFM.

Two hundred and twenty five, day-old Arbour Acre broiler birds were use to investigate the effect of graded dietary levels of Parkia biglobosa pulp meal (PBPM) on the performance, haematological and carcass parameters of the birds from 0-8 weeks of age. Five isocaloric and isonitrogenous diets were formulated to contain PBPM at 0,10,20, 30 and 40 percent respectively making a total of 5 treatments. Each treatment was replicated three times with 15 birds per replicate in a completely randomized design experiment. Feed and water were supplied ad libitum. Records taken included weekly weight changes and weekly feed intake. There was no record of mortality throughout the duration of the experiment. Results obtained showed a decrease in the bird’s performance as the dietary levels of the pulp increased. The final weight (g/b) and weight gain (g/b/day) decreased from 2122 and 33.91 for the control to1309 and 20.97 for the 40% inclusion level of PBPM meal respectively However birds placed on 10% dietary level had a performance that were not significantly (P>0.05) different from those placed on the control diet which were on standard broiler starter and finisher rations. Also it was observed that values obtained for the haematological parameters fall within the range often reported for healthy birds indicating that the pulp did not impart any deleterious effect on the health of the birds. It can be concluded that broiler chickens can be fed up to 10% dietary level of PBPM without adverse effect on the performance of the birds.

Deficit of conventional feed ingredients in meeting increased demand has led to an alarming hike in their prices culminating in sky rocketing cost of livestock feed. This has necessitated an urgent search for low cost and more readily available alternatives. This study was conducted to investigate the performance of broiler chicks fed diets containing graded levels of soaked and boiled Bambara nut seed meal (BNSM). One hundred and five (105), 2 week old broiler starter chicks were used for the experiment. The birds were randomly allotted into four dietary treatments with each treatments replicated thrice at seven birds per replicate in a completely randomized design. Five experimental diets were formulated containing processed BNSM designated as T1 (control diet with 0 % BNSM), while T2, T3, T4 and T5 had 5 % soaked BNSM, 10 % soaked BNSM, 5 % boiled BNSM and 10 % boiled BNSM, respectively. The experiment lasted for four (4) weeks. Feed and water were provided ad libitum. The results showed that birds fed processed BNSM diets had significantly (P<0.05) higher final weight and weight gain comparable to 702.38g and 19.99 g/bird/day in the control group. The values obtained from feed intake showed that T2 (64.74 g) had significantly (P<0.05) least value compared to other dietary treatments. Feed conversion ratio and feed cost per kg gain (N) were significantly (P<0.05) better in birds fed processed BNSM diets compared to 3.39 and N215.85 respectively in the control group. It was therefore concluded that processed BNSM improved performance of broiler chickens.     Le déficit d'ingrédients alimentaires conventionnels pour répondre à la demande accrue a conduit à une hausse alarmante de leurs prix, aboutissant à une flambée du coût des aliments pour le bétail. Cela a nécessité une recherche urgente d'alternatives peu coûteuses et plus facilement disponibles. Cette étude a été menée pour étudier la performance des poussins de départ de pouletsde chair nourris avec des régimes contenant des niveaux échelonnés de farine de graines de noix de Bambara trempées et bouillies. Cent cinq (105) poussins de départ âgés de 2 semaines ont été utilisés pour l'expérience. Les oiseaux ont été répartis au hasard en quatre traitements diététiques, chaque traitement étant répliqué trois fois à raison de sept oiseaux par réplique dans une conception complètement aléatoire. Cinq régimes expérimentaux ont été formulés contenant du 'BNSM'-Bambara nutseedmeal(Aliment de farine de graines de noix de bambara)- traité désigné comme T1 (régime témoin avec 0% de BNSM), tandis que T2, T3, T4 et T5 contenaient 5% de 'BNSM' imbibé, 10% de 'BNSM' imbibé, 5% de 'BNSM' bouilli et 10% de 'BNSM' bouilli, respectivement. L'expérience a duré quatre (4) semaines. L'alimentation et l'eau étaient fournies ad libitum. Les resultants ontmontré que les oiseaux nourris avec des régimes 'BNSM' transformés avaient un poids final et un gain de poids significativement plus élevés (P <0.05) comparables à 702.38 g et 19.99 g / oiseau / jour dans le groupe témoin. Les valeurs obtenues à partir de la consommation alimentaire ont montré que T2 (64.74 g) avait une valeur significativement moindre (P <0.05) par rapport aux autres traitements diététiques. Le taux de conversion alimentaire et le coût alimentaire par kg de gain (N) étaient significativement meilleurs (P <0.05) chez les oiseaux nourris avec des régimes 'BNSM' transformés par rapport à 3.39 et N215.85 respectivement dans le groupe témoin. Il a donc été conclu que le 'BNSM' transformé améliorait les performances despoussins de départ de poulets de chair.

The effects of graded levels of dehulled-and-cooked castor oil bean (Ricinus communis, L) meal on the performance of broiler starters were studied. Castor oil bean seeds were dehulled-and-detoxified by cooking in two stages at 1000C for 50 minutes per cooking. Sixty 7-day old unsexed broiler starters (Anak strain) were randomly divided into four isocaloric (2.88 mcal of ME/kg) and randomized design (CRD). Each group was fed one of four isolaric (2.88 Mcal of ME/kg) and isonitrogen (24% crude protein) diets containing 0%(control), 10, 15, and 20% levels of dehulled and cooked castor oil bean meal( CBM), respectively for five weeks. There were no significant (P>0.05) differences between birds fed the control diet and those birds fed the 10% CBM diets in all the parameters measured with the exception of packed cell volume (PCV). Inclusion levels above 10% caused significant (P>0.05) caused reduction in average daily feed intake and daily weight gain. However, the reduction in feed conversion ratio and protein efficiency reatio became significant (P<0.05) only at 20% inclusion level. PCV was depressed (P<0.05) by all the iunclusion levels of CBM. Overall, the birds fed the 20% dehulled-and-cooked CBm had the worst performance. It as concluded dehulled-and-cooked CBM could be included at the levels 10 and 15% in the broiler starter diets without much adverse efffects on the performance of the broiler starters.

Background: Animals eat to acquire the energy and building materials that they need to live and grow the nutrient required to achieve such, abound in phyto-materials. The synergistic, additive, or complementary immuno-modulatory effects of phytocomponents from A. senegalensis and Alium cepa were evaluated in this work. Methods: Seventy indigenously developed varieties of day-old broilers were divided in a completely randomized design(CRD) into 5 (n=14) treatment groups (T1-T5) treatments with 2 replicates per treatment. At the finisher level, 0.0, 0.2, 0.3, 0.4, and 0.5 kg of the A. senegalensis-garlic (ASG) cocktail was added to the normal finisher diet. Results: Feed consumption tends to increase significantly (p≤0.05) with the increased level of ASG Cocktail. values recorded 1405±17.9 g, 1450±21.5 g, 1310±20.6 g, 1450±17.3 g, 1340±15.3g for T1, T2, T3, T4, and T5 respectively were recorded. There is a significant difference (p≤0.05) in the total protein (TP) at different inclusion levels with 0.5% having the highest value of 57.95±4.07 g/dl. The triglycerides and cholesterol levels decrease as the ASG inclusion level increases which shows the anticholesteremic potency of the blend. There are significant increases (p≤0.05) in the albumin and globulin concentrations as the level of ASG inclusion increased. However, while there is a significant increase (p≤0.05) in the aspartate transaminase along the concentration gradient, the reverse is the case with regards to alanine transaminase. A significant decrease (p≤0.05) in bilirubin concentration along the inclusion gradient (except in T5). There was a significant increase (p≤0.05) in body weight across the inclusion gradient except in T3. The Feed Conversion Ratio (FCR) follows a regular pattern with a range of 0.51-0.53 except for the birds fed with 0.3% inclusion (T3) that recorded a higher (poor) value of 0.89. Conclusion: Supplementation with ASG cocktail improves the performance and the immune-competence of the bird at the finisher stage

There are well documented complications associated with the continuous use of antibiotics in the poultry industry. Over the past few decades, probiotics have emerged as viable alternatives to antibiotics; however, most of these candidate probiotic microorganisms have not been fully evaluated for their effectiveness as potential probiotics for poultry. Recent evaluation of a metagenome of broiler chickens in our laboratory revealed a prevalence of Lactobacillus reuteri (L. reuteri) and Actinobacteria class of bacteria in their gastrointestinal tract. In this study Lactobacillus reuteri and Streptomyces coelicolor (S. coelicolor) were selected as probiotic bacteria, encapsulated, and added into broiler feed at a concentration of 100 mg/kg of feed. In an 8-week study, 240 one day-old chicks were randomly assigned to four dietary treatments. Three dietary treatments contained two probiotic bacteria in three different proportions (L. reuteri and S. coelicolor individually at 100 ppm, and mixture of L. reuteri and S. coelicolor at 50 ppm each). The fourth treatment had no probiotic bacteria and it functioned as the control diet. L. reuteri and S. coelicolor were added to the feed by using wheat middlings as a carrier at a concentration of 100 ppm (100 mg/kg). Chickens fed diets containing L. reuteri and S. coelicolor mixture showed 2% improvement in body weight gain, 7% decrease in feed consumption, and 6–7% decrease in feed conversion ratios. This research suggests that L. reuteri and S. coelicolor have the potential to constitute probiotics in chickens combined or separately, depending on the desired selection of performance index.

ABSTRACT The objective of this work was to evaluate the effect of increasing levels of guava agro-industrial waste (GAW) on the ingestive behavior of Santa Inês lambs. Forty non-castrated sheep of the Santa Inês breed were used, at an initial weight of 21.33 ± 2.62 kg, and at the age of 120 days, distributed in a completely randomized design, with five treatments and fed with increasing GAW levels (0.0, 7.5, 15.0, 22.5 and 30.0%). The average daily gain (ADG) showed orthogonal contrast (P <0.05), in which the animals that ingested the control diet had lower performances. The animals with GAW added to the diet obtained more significant weight gains reflected by a better feed conversion. Among the variables, idleness, feeding, and total chewing time had a significant effect (P<0.05); animals spent more time idle at the 30.0% inclusion level and less time in the control group. However, the means of the 7.5, 15.0, and 22.5% GAW inclusion levels were statistically similar to the control group and the 30.0% level. There was a significant effect (P<0.05) on feed efficiency, with the lowest values being presented for the control group and the highest values at the 30% inclusion level of GAW. The 30.0% GAW feed for lambs in confinement reduces feed time, and total chewing prolongs idleness and increases feed efficiency without compromising dry matter intake, neutral detergent fiber intake, and ADG.

A total of 300 day old broiler chicks (Hubbard) were assigned to 30 floor pens (10 birds per pen) under cyclic heat stress. Three diets including a control, as well as two levels of grape seed powder (GSP) and zinc (OZ) at the rates of 2.5 g/kg GSP + 50 mg/kg OZ and 5 g/kg GSP + 50 mg/kg OZ, were supplied to the broilers for 35 days. According to the results, broiler feed intake improved (p < 0.05) in GSP + OZ groups from 3–5 weeks and on an overall basis compared to the control diet. Body weight increased (p < 0.05) in GSP-5 + OZ-50 during weeks 2–5 and on an overall basis. The findings indicated that feed conversion ratio (FCR) decreased (p < 0.05) during week 5 in broilers supplemented with GSP-5 + OZ-50. The antibody titer (HI) against Newcastle disease (ND) was higher (p < 0.05) in GSP + OZ groups compared to control treatment. The value of malondialdehyde (MDA) decreased (p < 0.05) under GSP + OZ diets compared to control. Moreover, paraoxonase (PON1) was higher (p < 0.05) in GSP + OZ groups compared to untreated broilers. In conclusion, GSP + OZ positively supported growth traits, reduced MDA, and augmented PON1 and HI titer against ND in broilers exposed to heat stress.

ABSTRAK. Penelitian ini bertujuan untuk mengevaluasi performa tiga strain ayam broiler yang umumnya dipelihara di Aceh. Materi yang digunakan adalah 150 ekor anak ayam broiler (DOC) strain Cobb 500, CP 707, dan MB 202 masing-masing berjumlah 50 ekor. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 3 perlakuan dan 5 ulangan. Setiap ulangan merupakan unit percobaan yang masing-masing terdiri dari 10 ekor anak ayam. Perlakuan adalah tiga strain ayam broiler: Cobb 500 (P1), CP 707 (P2), dan MB 202 (P3). Parameter yang diamati meliputi pertambahan berat badan, konsumsi ransum, konversi ransum (FCR), mortalitas, dan Income over Feed and Chick Cost (IOFCC). Hasil penelitian memperlihatkan performa broiler dipengaruhi oleh jenis strain. Strain MB 202 dan CP 707 memiliki bobot badan akhir (6 minggu) dan konsumsi ransum nyata (P0,05) lebih tinggi daripada Cobb 500. Angka konversi ransum tidak memperlihatkan perbedaan yang nyata antara ketiga strain pada semua umur panen. Nilai IOFCC tertinggi dipengaruhi oleh jenis strain dan lama pemeliharaan. Dari hasil penelitian dapat disimpulkan bahwa performa broiler dipengaruhi oleh kemampuan adaptasi strain terhadap iklim setempat (pesisir Aceh) pada periode berbeda-beda yang dapat memengaruhi tingkat keuntungannya. Strain Cobb 500 memiliki kemampuan adaptasi lebih baik selama periode awal, sedangkan CP 707 dan MB 202 selama periode akhir. (Evaluation of performances and income over feed chick cost (iofcc) of three broiler chicken strains commonly marketed in Aceh) ABSTRACT. The study aimed to evaluate the performances and Income over Feed and Chick Cost (IOFCC) of three broiler chicken strains commonly marketed in Aceh. As many as 150 chicks of three different broiler strains (50 birds each) were used in this study. The study was performed into Completely Randomized Design (CRD) consists of 3 treatments and 5 replications creating 15 experimental units containing 10 birds each. The treatments were 3 different strains of broiler chickens i.e. Cobb 500, CP 707, and MB 202. The birds were reared up to 6 weeks to expose their performances recorded as final body weight, body weight gain, feed intake, and feed conversion, as well as mortality. Economic value was evaluated by calculating IOFCC. Results of study showed that performances of broilers were significantly (P0,05) influenced by the strains. Strains MB 202 and CP 707 represented more superior than Cobb 500 for 5−6 weeks of raising periods. However, the later was not inferior during initial phase close to 4 weeks. There were no significant differences in FCR among all strains for different ages. The IOFCC related to the strains and their marketing ages. The highest IOFCC was obtained by Cobb 500, CP 707, and MB 202 as they were sold at the ages of 4, 5, and 6 weeks, respectively. In conclusion, the achievements of the performances in various broiler strains were affected by the site climate (Aceh) in different stages of their ages. Cobb 500 had proper adaptation during starter, while CP 707 and MB 202 appeared seem to be better than Cobb 500 during finisher period.
