The proper spatial distribution of chickens is an indication of a healthy flock. Routine inspections of broiler chicken floor distribution are done manually in commercial grow-out houses every day, which is labor intensive and time consuming. This task requires an efficient and automatic system that can monitor the chicken’s floor distributions. In the current study, a machine vision-based method was developed and tested in an experimental broiler house. For the new method to recognize bird distribution in the images, the pen floor was virtually defined/divided into drinking, feeding, and rest/exercise zones. As broiler chickens grew, the images collected each day were analyzed separately to avoid biases caused by changes of body weight/size over time. About 7000 chicken areas/profiles were extracted from images collected from 18 to 35 days of age to build a BP neural network model for floor distribution analysis, and another 200 images were used to validate the model. The results showed that the identification accuracies of bird distribution in the drinking and feeding zones were 0.9419 and 0.9544, respectively. The correlation coefficient (R), mean square error (MSE), and mean absolute error (MAE) of the BP model were 0.996, 0.038, and 0.178, respectively, in our analysis of broiler distribution. Missed detections were mainly caused by interference with the equipment (e.g., the feeder hanging chain and water line); studies are ongoing to address these issues. This study provides the basis for devising a real-time evaluation tool to detect broiler chicken floor distribution and behavior in commercial facilities.

The presence equipment (e.g., water pipes, feed buckets, and other presence equipment, etc.) in the poultry house can occlude the areas of broiler chickens taken via top view. This can affect the analysis of chicken behaviors through a vision-based machine learning imaging method. In our previous study, we developed a machine vision-based method for monitoring the broiler chicken floor distribution, and here we processed and restored the areas of broiler chickens which were occluded by presence equipment. To verify the performance of the developed restoration method, a top-view video of broiler chickens was recorded in two research broiler houses (240 birds equally raised in 12 pens per house). First, a target detection algorithm was used to initially detect the target areas in each image, and then Hough transform and color features were used to remove the occlusion equipment in the detection result further. In poultry images, the broiler chicken occluded by equipment has either two areas (TA) or one area (OA). To reconstruct the occluded area of broiler chickens, the linear restoration method and the elliptical fitting restoration method were developed and tested. Three evaluation indices of the overlap rate (OR), false-positive rate (FPR), and false-negative rate (FNR) were used to evaluate the restoration method. From images collected on d2, d9, d16, and d23, about 100-sample images were selected for testing the proposed method. And then, around 80 high-quality broiler areas detected were further evaluated for occlusion restoration. According to the results, the average value of OR, FPR, and FNR for TA was 0.8150, 0.0032, and 0.1850, respectively. For OA, the average values of OR, FPR, and FNR were 0.8788, 0.2227, and 0.1212, respectively. The study provides a new method for restoring occluded chicken areas that can hamper the success of vision-based machine predictions.

Two experiments were carried out to ascertain the nutritional value of potato waste meal (PW) as a replacement for corn in practical poultry diets using 320 male and 320 female Cobb chicks fed from 1-day-old to 46 days (exp. 1) and 49 days (exp. 2) a basal cereal-based diet containing soybean and fishmeals or test diets each containing 50 g, 100 g, 150 g, 200 g and 300 g PW/kg. In both experiments, the diets were analyzed for elemental and amino acid composition, and the growth responses on the test diets were evaluated individually over a period of 28 days and 46 days or 49 days of ad libitum feeding. Although PW appeared limiting with respect to methionine and cystine, arginine and the aromatic amino acids, it was found that upon supplementation with methionine (0.5 g/kg), the test mixtures exhibited a synergistic effect compared with controls, and that this potato byproduct can be considered a good substitute ingredient for a proportion (200 g/kg) of the ground corn in a practical diet for broiler chickens. Feeding PW at a rate of up to 200 g/kg resulted in optimum biological response and monetary returns. The inclusion of up to 300 g/kg PW in the diets did not increase wetness of the litter or hardness of pellets, two factors reported earlier which could limit the use of PW in animal diets.

Vitro Effect

Cytokines are proteins secreted by cells of innate and acquired immunity, produced in response to various antigens and responsible for mediating several function of these cells. Our study evaluated the profile of cytokines interleukin 5 (IL-5) and interferon gamma (IFN-γ), induced in lymphocytes of broiler chickens in response to secondary fungal metabolites ochratoxin A (OTA) and deoxynivalenol (DON) at concentrations of 0.001, 0.01, 0.1 and 1 μg/ml. The quantification of the cytokines was analysed at 24, 48 and 72 h after incubation with mycotoxins, using real-time PCR (qRT-PCR). The results obtained showed that OTA induced mRNA synthesis of IL-5 at concentrations 0.001, 0.1 and 1 μg/ml after 24 h of lymphocyte incubation, while at 48 h only the expression of the IL-5 cytokine at a concentration of 1 μg/ml (P<0.05) was detected. DON in a concentration of 1 μg/ml induced the expression of IL-5 in the lymphocytes only at 48 h post-incubation period (P<0.05). Regarding IFN-γ, gene expression was not observed in the lymphocytes of broiler chickens incubated with OTA and DON. The data obtained represent a profile of response mediated by T helper 2 cells to the exposure of broiler chicken immune cells to different concentrations of OTA and DON.

Fast Growth Rate

Continuous genetic selection and improvement in nutrition have led to a very fast growth rate in modern strains of broiler chickens. Metabolic disorders such as ascits, sudden death syndrome and leg problems are related to a rapid early growth rate in poultry, especially in broilers, and their incidence can be decreased by slowing early growth. The use of management tools to reduce metabolic disorders that rely primarily on decreasing feed consumption, The feed restriction programs is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken in alleviate the incidence of some metabolic disorders and can be used to reduction the unfavorable effects of fast growth rate in broiler chicken production industry, and could be profitable in broiler chickens production efficiency. This article implicated on new findings in about different feed restriction programs effects on these problems in broiler chickens.

The aim of the study is to increase the productive qualities of broiler chickens by including ultrafine silicon oxide into main diet. During the experiment, the biological effect of ultrafine silicon oxide on broiler chickens was estab-lished. Use of ultrafine SiO2 particles for poultry feeding contributed to an increase in the number of red blood cells and content of total protein and albumins. By the end of the experiment, the number of red blood cells in birds in-creased by 17.43% (P≤0.001) – in the blood of birds of the first experimental group, 16.51% (P≤0.01) – the second one, 20.80% (P≤0.001) – the third experimental and 21.71% (P≤0.001) – the fourth experimental group, compared with the indicator of the control group. The amount of total protein in blood serum of chickens of the first and the second experimental groups increased by 1.36-1.39 %, in the third and fourth ones there was a significant (P≤0.05) increase by 5.45 and 3.05%, respectively. The blood glucose content of chickens in the experimental groups is higher by 8.04-23.65% compared to this indicator with ones in the control group. During the experiment feed con-sumption per 1 kg gain of live weight decreased: in the first experimental group by 3.00 % in the second by – 0.50 %, the third – 6.00 % the fourth– by 4.50 %, compared to this with the control group. The chicken’s vibrancy of the first the experimental group was higher by 4.77 %, the second – by 6.20 %, the third – by 19.25 % and the fourth– by 11.59% than in the control one. Consequently, when converting the feed energy into the body energy of a broiler chicken, the energy conversion coefficient of the experimental group of poultry is higher than that of the control one by 7.16-21.76 %. Thus, the most optimal dose for further research was determined.

Cloacal temperature (CT) of broiler chickens is an important parameter to classify its comfort status; therefore its prediction can be used as decision support to turn on acclimatization systems. The aim of this research was to develop and validate a system using the fuzzy set theory for CT prediction of broiler chickens. The fuzzy system was developed based on three input variables: air temperature (T), relative humidity (RH) and air velocity (V). The output variable was the CT. The fuzzy inference system was performed via Mamdani's method which consisted in 48 rules. The defuzzification was done using center of gravity method. The fuzzy system was developed using MAPLE® 8. Experimental results, used for validation, showed that the average standard deviation between simulated and measured values of CT was 0.13°C. The proposed fuzzy system was found to satisfactorily predict CT based on climatic variables. Thus, it could be used as a decision support system on broiler chicken growth.

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.
