The residue originated from antibiotics and hormones had been thought to carry out adverse effects for the human who consume meat processed from the broilers treated by antibiotic feed additive. For this reason, using an alternative additive such as probiotic might produce healthier meat. The objective of the recent study was to evaluate administering different levels of probiotic yakult + tape yeast (YTy) into the mixing of rice bran + corn bran (RCB) to replace 30% of the commercial diet to carcass yield and abdominal fat of broilers. As many as 100 broiler chicks, Cobb strain, were reared up to 5 weeks in this study. The study was designed into a Completely Randomized Design with subsampling consisted of 5 treatments, 4 replications, and 2 sub samples. Broiler commercial diet with the market code of CP 511 Hi-provite manufactured by PT Charoen Pokphand was used for a positive control diet (P0+). The RCB feeds were mixed with 0, 10, 20, and 30 ml/kg of probiotic YTy then being used to replace 30% of the commercial diet to build experimental diets P0-, P1, P2, and P3, respectively. The results of the recent study indicated that administering 10‒30 ml/kg of probiotic YTy highly significantly (P<0.01) increased the weights of the whole carcass and carcass parts. The percentages of whole carcasses among P1, P2, and P3, however, were not statistically different. The percentage of the breast significantly (P<0.05) increased while the percentage of the back significantly (P<0.05) decreased. Although statistically not significant differences, the abdominal fat percentage tended to decline. In conclusion, administering a probiotic YTy in the diet increased the percentage of the whole carcass and tended to reduce the abdominal fat of the broiler.

ABSTRACT A trial was conducted to evaluate a feed additive containing epoxidase activity from a bacterium (Mycofix-S) as a potential protection against the adverse effects of 2.5 ppm dietary T-2 toxin in male growing broiler chickens. A total of 144 one-day-old Ross 308 male chicks were individually wing-banded and allotted into each of the four experimental groups. Group 1: negative control, no T-2 toxin or additive; group 2: Mycofix-S, 2.5 g/kg; group 3: positive control, 2.5 ppm T-2 toxin; group 4: 2.5 ppm T-2 toxin + 2.5 g/kg Mycofix-S. Feed and water were provided ad libitum for 28 days (days 1 to 28 of age). Each experimental treatment was replicated 6 times, with 6 birds per replicate pen. Response variables included performance parameters, serum activity of alkaline phosphatase (ALP) and amylase, relative weight of selected organs and histology of the upper digestive system. T-2 toxin at 2.5 ppm significantly (P = 0.016) decreased the 28-day body weight gain and cumulative feed intake without affecting feed conversion. The feed additive counteracted these adverse effects. Serum enzyme activities were not significantly (P>0.05) affected for the four experimental groups but when data from the groups receiving T-2 toxin was pooled and compared against the pooled data from groups without the toxin a significant decrease in amylase activity was observed in chickens receiving T-2 toxin. The histological examination of the upper digestive system revealed lesions in mouth, esophagus, proventriculus, gizzard and duodenum in the chickens fed T-2 toxin without the additive. Chickens fed T-2 toxin plus the additive showed lesions in the same tissues except in the duodenum. The results of the present study show that the addition of 2.5 g/kg of the feed additive tested protects against adverse effects on performance and also the integrity of the duodenal mucosa.

This research was conducted for 42 days, in order to determine the effects of fluctuate lighting program on production and carcass characteristics of broiler chickens. 300 day old Ross 308 chicks were used. Chicks were randomly distributed to 2 lighting groups which were normal lighting (control) and fluctuate lighting, and each group was divided in to 3 replicates containing 50 chicks. For both groups lighting was arranged as 23 hours of lighting versus 1 hour of dimming. Control group was subjected to constant lighting of 20 lux/m2 for the days 0-21, and 5 lux/m2 for the days 22-42; while in the fluctuate lighting group was subjected to lighting of 5 lux/m2 for 45 minutes and additional 20 lux/m2 for 15 minutes every hour. There were no differences of final body weight, weekly body weight gain, cumulative feed intake, cumulative feed conversion ratio, viability, foot and leg problems, hot and cool carcass weight, thigh weight, breast weight, wing weight, back weight, liver or heart weights. However, there were statistically significant differences of gizzard weight and abdominal fat weight between two groups. In conclusion, gizzard and abdominal fat weights of broilers subjected to fluctuate lighting are less than control. This suggests that fluctuate lighting can be used to lower abdominal fat which is an important problem in broilers.

The effects that Neem leaf extract on overall growth, feed conversion ratio (FCR), dressed weight and organs weight of broiler chickens to justify its inclusion in the diet of growing broiler chickens. 120 day old chicks divided into four treatment groups T1, T2, T3 and T4 of thirty (30) birds each were administered clean drinking water with 3gm, 4gm, 5gm and 0g neem extract respectively. Impacts of neem extract treatments on growth indices suggested that Neem extract favored growth with final body weight range of 1709gm and 1763gm. Organ weights showed no deviation from standard values for healthy broiler birds. Highest growth was observed in group T3 (1763.6±141.37gm) followed by T1, T2 and lowest was in T4 group (1565.4±161.25gm). Birds on 5gm of Neem extract in their drinking water out performed birds in other treatments in assessed growth rate indices. We therefore conclude that 5gm of Neem extract in their drinking water growing broiler birds encourages healthy growth and may serve as supplements for antibiotics, especially when birds are raised in areas with minimal access to veterinary service.

Background and Objectives: Tsukamurella species are Gram-positive rods that exist in a broad range of environments. In this study, the efficacy of heat-killed Tsukamurella inchonensis on growth performance, intestinal morphology, and humoral immune responses of broiler chicken was evaluated. Materials and Methods: Ross broiler chicks in the cage were randomly allocated to five groups. Trail diets were prepared by adding 106 cells per bird of heat-killed T. inchonensis into the basal trading diet for group 1 continuously dosed for 24 h from day 1 to day 13, and for group 2, 24 h on days 1 to 5; 8; 9, 12 and 13. Group 3 was received 10 6 bacteria as a subcutaneous injection on days 1, 6, and 12. Groups 4 and 5 were not received T. inchonensis during the experiment period. Results: Feed intake (FI) and feed conversion ratio (FCR) were not altered by different delivery methods of T. inchonensis supplementation. The pulsed dosed in feed tended to provide higher body weight gain (BWG) than the negative control groups. T. inchonensis treatments, never less of the ways of delivery, boosted (P<0.05) the antibody titers to Newcastle disease virus (NDV), and avian influenza (AI) (H9N2) virus, especially when broiler chickens treated with pulse dosed in the feed. The most significant intestinal development (p<0.05) was observed between groups 1 and 2. There were no significant differences in the thymus, liver, and bursa of Fabricius relative weight. Still, there were significant increases in the relative weight of spleen on day 14 in vaccinated chickens treated with T. inchonensis pulse dosed. Conclusion: It seems that the supplementation of T. inchonensis in the broiler diet can improve intestinal morphology and humoral immune response, which was represented by increased antibody response to NDV, and AI vaccines significantly, but it cannot affect FI and FCR.

The aim of the study was to determine the effect of supplementing broiler chickens’ diets with halloysite on daily body weight gain (BWG), feed conversion ratio (FCR), daily water consumption (DWC), and some broiler house hygiene parameters. The trial was conducted on 18,000 broiler chickens divided into two groups throughout the 42-day (D) rearing period. The birds were fed complete diets without (group C) or with halloysite addition (1%, group E) from D8 of rearing. No difference in the mortality rate was observed between groups C and E. Birds from group E had a tendency (0.05 < p < 0.10) towards a higher body weight at D32 and D42, a higher BWG, and a lower FCR compared to group C during the entire rearing period. Average DWC differed only in the finisher period, with a tendency towards lower overall DWC in group E. The concentration of ammonia in the air from D21 to D35 was increased more than 5-fold in group C but only 1.5-fold in group E. In conclusion, the use of halloysite as a feed additive in the diet of broiler chickens resulted in a reduction in feed consumption per unit of BWG and higher utilisation of crude protein, which led to improved environmental conditions.

The aim of this study was to assess the effect of low environmental temperature on growth, feed conversion, performance and selected biochemical and haematological indicators in broiler chickens. The decrease in air temperature since the 22nd day of growth influenced significantly (p < 0.05) the level of total proteins, uric acid, phosphorus (in female broiler chickens), glucose (in male broiler chickens), haemoglobin (in female broiler chickens) and liver weight (in male broiler chickens). The temperature influenced significantly (p < 0.01) the level of triiodothyronine, haemoglobin (in male broiler chickens), haematocrit, abdominal fat content (in male broiler chickens), and heart weight too. The results have clearly confirmed that during growth, the decrease in environmental temperature (cold stress) negatively influenced some indices of performance and blood system in broiler chickens.

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.

Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

This study aims to examine the use of red sweet potato flour on slaughter weight, percentage ofcarcass weight, and abdominal fat in broiler chickens fed with additional red sweet potato flour. Thisresearch was conducted in April to May 2018, housed in the Raman Farm enclosure in Puosu JayaVillage, Konda District, Konawe Selatan District. The material used in this study was 64 weeks oldbroiler chickens, with 64 feed ingredients used as the concentrate, corn, bean, sweet potato flour. Theequipment used is a scale, a colony cage made of wire-lined wood and measuring 4m x 2m, which isdivided into 16 plots and the size of each 1m x 0.5m, each story is equipped with a place to eat anddrink, 40-watt incandescent balloons and other equipment such as scales, ovens, sample grinders,basins, plastics, and gutters. This study was designed using a complete randomized design with fourtreatments and four replications, where four treatments consisted of P0 basic ration (Control), P1:basic ration containing 4% red sweet potato flour, P2: elemental percentage containing 6% red sweetpotato flour, and P3: basic ration contains 8% red sweet potato flour. The variables observed in thisstudy were cutting weight, carcass percentage, and abdominal fat of broiler chickens. The results ofthe analysis of variance showed that the administration of red sweet potato flour had no significanteffect (P> 0.05) on the percentage of carcasses and abdominal fat of broiler chickens. Broiler chickenaged five weeks. It was concluded that the provision of different red sweet potato flour in feed did notsignificantly affect slaughter weight, carcass weight, and abdominal fat percentage of broilerchickens. There is a tendency for broilers fed with red sweet potato flour to have heavier cut weights,a more significant portion of carcasses and an increase in the level of red yam, and a decrease inabdominal fat content and the addition of red yam levels in the feed.
