Ayam petelur merupakan ternak yang mudah stress dan rentan terhadap penyakit. Guna mengatasi keadaan tersebut perlu dicari alternatif bahan herbal yang tidak menimbulkan residu pada telur ayam yaitu dengan memberikan pakan tambahan fermentasi tepung daun binahong. Binahong merupakan salah satu tanaman yang dapat meningkatkan vitalitas dan daya tahan tubuh. Kandungan fitobiotik pada tepung daun binahong (fenol 85,30 mg/kg, total flafonoid 47,40 mg/kg, saponin 66,00 mg/kg, dan alkaloid 2,60 mg/kg). Unggas yang memiliki sistem pencernaan tunggal kurang baik dalam mencerna pakan berserat kasar tinggi. Kebutuhan serat kasar pada ayam petelur maksimal 7% maka, dilakukan analisis manfaat fermentasi menggunakan EM4. Dalam penelitian terdahulu menyebutkan bahwa EM4 menghasilkan sejumlah besar enzim mencerna serat kasar seperti selulase dan mannase. Keuntungan Lactobacillus dalam EM4 dalam mencerna serat kasar adalah karena bakteri tidak menghasilkan serat kasar dalam aktivitasnya, sehingga mereka lebih efektif dalam menurunkan serat kasar. Fermentasi dapat meningkatkan nilai gizi dan juga palatabilitas. Pemberian pakan tambahan fermentasi tepung daun binahong  sebagai feed adiktif memiliki potensi terhadap peningkatkan sistem imun sehingga ayam sehat, maka produksi telur akan meningkat dan stabil. Laying hens are animals that are easily stressed and susceptible to disease. In order to overcome this situation, it is necessary to find alternative herbal ingredients that do not cause residues in chicken eggs, namely by providing additional feed with fermented binahong leaf flour. Binahong is one of the plants that can increase vitality and endurance. Phytobiotic content in binahong leaf flour (phenol 85.30 mg/kg, total flavonoids 47.40 mg/kg, saponins 66.00 mg/kg, and alkaloids 2.60 mg/kg). Poultry that has a single digestive system is not good at digesting high crude fiber feed. The need for crude fiber in laying hens is a maximum of 7%, so an analysis of the benefits of fermentation using EM4 was carried out. In previous studies, it was stated that EM4 produces a large number of enzymes digesting crude fiber such as cellulase and mannase. The advantage of Lactobacillus in EM4 in digesting crude fiber is that bacteria do not produce crude fiber in their activity, so they are more effective in reducing crude fiber. Fermentation can increase nutritional value and also palatability. The addition of fermented binahong leaf flour feed as an addictive feed has the potential to increase the immune system so that chickens are healthy, so egg production will increase and be stable.

Decreasing egg production is an initial symptom of various diseases that infect commercial layer chickens. Diagnosis of diseases causing the decrease in egg production without high mortality rate is often thought to be caused by other poultry diseases because of the many similarities in manifestation between one disease and another. Avian influenza is a zoonotic infectious disease in poultry that can lead to high economic losses. This study aims to determine the contribution of avian influenza virus (AIV) infection to commercial laying hens showing symptoms of decreased production. The samples were oropharyngeal swabs of commercial laying hens which had symptoms of decreased production at productive age. Laboratory tests were carried out by histopathological examination, detection and identification of AIV with real time reverse transcriptase polymerase chain reaction (qRT-PCR) and isolation with the viral culture technique on fertile chicken eggs. The results showed that there was type A AIV infection based on the qRT-PCR (matrix) test, but the subtypes were not identified (H5, H7, H9). The results of the isolation of the virus in the fertile chicken eggs showed embryonic death in which all embryonic organs show hemorrhages. Allantoic fluid does not agglutinate chicken red blood cells. Histopathological features of the pathognomonic lesions in lungs infected with AIV were severe congestion and hemorrhages. Based on the results of the study, it was concluded that there was a contribution of type A AIV infection. Early diagnosis of AIV could determine more appropriate actions, including control, prevention and eradication.

ABSTRACTThe use of antibiotics in chicken feed is currently banned because it can cause resistance to pathogenic bacteria and cause residues in products. This study aimed to see the effect of drinking water containing uronic acid extracted from Sargassum crassifolium (S. crassifolium) on the physical and chemical quality of Lohmann chicken eggs. One hundred and twenty laying hens were divided into 2 groups: (1) chickens given commercial feed containing antibiotics and (2) feed without additional antibiotics. The chickens were randomly assigned to one of the 5 brown seaweed supplementation treatments in drinking water A1=0.0% S.crassifolium (control); A2=2.5% S.crassifolium; A3=5.0% S.crassifolium; A4=7.5% S.crassifolium; A5=10.0% S.crassifolium. The study used a completely randomized factorial design of 5 treatments, 2 factors, and 3 replications. Each replication consisted of 6 heads of laying hens. There were no differences between treatments on the performance of laying hens (egg production, egg weight, egg mass, feed conversion); physical quality (eggshell, egg yolk, egg white, shell thickness, egg yolk, Haugh unit, egg index) and chemistry (superoxide dismutase production, thiobarbituric acid reactive substances (TBARS) and Lohmann chicken egg cholesterol) but there was a difference in feed intake. The uronic acid extracted from S. crassifolium has not been able to increase the production and quality of Lohmann chicken eggs.Keywords: lohmann chicken, quality of eggs, Sargassum crassifolium, uronic acid

Poultry Farming

Compound feed are subject to requirements for their composition, since they use several types of grains that contain anti-nutritive substances that reduce the digestibility and use of nutrients. One of the tasks of domestic poultry farming is to reduce losses by increasing the digestibility and accessibility of feed. Among the most effective ways to solve this problem is to add enzymes to the feed of poultry. The inclusion of enzyme drugs in the composition of compound feed contributes to the inactivation of anti-nutritive substances, which contributes to an increase in the coeffi cient of digestibility of nutrients. The purpose of the work was to establish the feasibility and eff ectiveness of the enrichment of compound feed used in the production technology of chicken eggs with mixtures of enzyme drugs of domestic production of Amylosubtilin G3x, Cellolux-F and Protosubtilin G3x. Three groups of laying hens with 57 heads in each have been formed: a control group and two experimental groups. The duration of the experiment was 420 days. Laying hens of the control group have been received farm compound feed depending on their age. Laying hens of the 1st experimental group have been received compound feed of the control group enriched with the enzymes Amylosubtilin G3x and Cellolux-F depending on the age. In the compound feed of laying hens of the 2nd experimental group enzyme drugs were additionally introduced depending on the age Amilosubtilin G3x and Protosubtilin G3x. Higher egg production rates have been observed in the 1st experimental group – 357,81 eggs, which was 6,48 % higher than in the control group and 1,84 % higher than in the 2nd experimental group. The weight of eggs of laying hens of the 1st experimental group was 1,85 g or 2,97 % more, and the 2nd experimental group was 0,7 g or 1,12 % more than in the control group. The diff erence between the egg weight in laying hens of the 1st and 2nd experimental groups was 1,85 % or 1,15 g. The lowest feed consumption of 1,37 kg for the production of 10 eggs was in the laying hens of the 1st experimental group, which was less than the indicator of the control group by 10,94 and by 4,2 % than in the 2nd experimental group.

SUMMARY The current study aims to evaluate the zootechnical performance, quality of eggs, and the immune system of the laying hen's upon supplementing their feed with the flour of the mushroom Agaricus blazei. A total of 210 Hisex Brown® hens, 67 weeks old, were distributed in a completely randomized design with five treatments (control [0%], 0.04%, 0.08%, 0.12% and 0.16% of mushroom meal) with seven replicates and six birds per experimental unit. Were evaluated the zootechnical performance (feed intake, egg production [per day and housed], marketable egg production, egg weight and egg mass, feed conversion per dozen and egg mass, and viability);egg quality (specific weight, Haugh units, weight and percentage of components, shell thickness and yellow intensity of the egg yolks); and the hemogram (erythrogram and leukogram). Mainly, different levels of mushroom meal, were includedin laying hens feeds significantly (p<0.05)egg mass and feed intake. However, the leukogram and the erythrogram remained within the reference values, indicating that the birds were healthy. The addition of different levels of Agaricus blazei flour in the laying hens feed did not promote changes in the egg quality, in the immune system, and in the zootechnical performance, except for the feed intake which reduced with the inclusion of mushroom flour and eggs mass in which the 0.07% level promoted the maximization of this parameter.

The Impact

Insufficient nutrient supply can impair the immune system, which is important for animal health and welfare. Since chicken can partly hydrolyze phytate, which is the primary phosphorus storage in plant seeds, a reduction of mineral phosphorus in the diets could be an option for more sustainable egg production. Laying hens require high concentrations of calcium that might inhibit the function of endogenous enzymes for phytate hydrolyzation. The objective of this study was to characterize the impact of standard and reduced dietary phosphorus and calcium concentrations on the number and functionality of immune cells in the peripheral and gut-associated immune system in a white and brown laying hen strain. Reduced mineral phosphorus enhanced several immune parameters such as B cells in blood and IgA concentrations in bile in both strains, and peripheral monocytes and T cells in cecal tonsils in brown hens. Reduced calcium levels resulted in lower numbers of T cells in blood and cecal tonsils in both strains, suggesting negative effects on adaptive immunity. Differences between the two strains were found in almost all immune parameters. Results suggest a potentially beneficial effect of reduced dietary mineral phosphorus on the immune system that is dependent on the genetic background.

Chicken Eggs

Nowadays, the pattern of people's lifestyle is increasing, one of which can be seen from the high intake of nutrients, especially those containing protein. One of the most commonly consumed animal proteins comes from eggs. Generally, eggs consumed come from bird species, such as chickens, ducks, and geese, but smaller eggs such as fish eggs are sometimes also used as a mixture in dishes. However, of the various types of eggs, purebred chicken eggs are the most popular among the public compared to other eggs. The purpose of this study was to determine the amount of production costs used in the business of purebred laying hens, to determine the variable which affects the amount of egg production from laying hens, and to determine the advantages of breeding broilers of laying hens. The results of the study showed that the income obtained in the business of raising laying chickens, with a business scale of 500 chickens was IDR 155,694,300.00, for a business scale of 1,500 was IDR 523,455,51400, and for a business scale of more than 5,000 was IDR1,850,211,903.00. Factors that had a significant effect on the amount of production of purebred laying hens was the feed factor (X2) of 9.7073 and the business of laying hen was profitable.Dewasa ini, pola kehidupan masyarakat semakin meningkat, salah satunya dapat dilihat dari tingginya asupan gizi, terutama yang mengandung protein. Salah satu protein hewani yang paling umum dikonsumsi masyarakat adalah berasal dari telur. Umumnya telur yang dikonsumsi berasal dari jenis-jenis burung, seperti ayam, bebek, dan angsa, akan tetapi telur-telur yang lebih kecil seperti telur ikan kadang juga digunakan sebagai campuran dalam hidangan. Namun dari berbagai jenis telur tersebut telur ayam ras yang paling diminati oleh masyarakat dibanding telur lainnya.

Highdem and for eggs requires a significant increase in production volumes subject to the standards of their quality. One of the components of the egg providing its safety and quality is the shell, which accounts for about 10-12% mass of the egg. The formation of eggs in chickens is a complex process, which is carried out within 24-27 hours, from which about 17-20 hours is given to form the shell. Since the main number of eggs chickens are demolished in the first half of the day, most of the calcification period of the egg shel falls on the dark period of day when the chicken stops to eat. A study was conducted to in vestigate the influence of an increased dose of calcium in the form of limestone particles when feeding it in the afternoon on the productivity and quality of chicken eggs. For this, two groups of laying-hens were formed, the mix feed for which consisted of the same components of cereal and protein-vitamin feeds, but was distingueished by calcium content, namely: in the control group in the mix feed, which was fed both in the morning and in the afternoon, was 3,5% calcium in the form of limestone thin and coarse grinding. The chickens of the experimental group in the morning were fed by mix feed with a calcium content of 1.5%, and in the afternoon - with a calcium content of 7% in the form of coarse limestone. Based on the research, it was found that during the 30-week period of productivity, the survival of chickens in the experimental groups was the same. Chickens of the experimental group reached 95% egg production at the age of 186 days, which his 5 days before the control group. Egg production on the middle and initial laying-hens in the experimental group for the whole production period was 178,4 eggs and 173,3 eggs, which is 6,2 and 7,0 eggs more than in the control group. The feeding of the chickens of the experimental group in the afternoon of mix feeds with an elevated calcium content contributed to an increase in the mass of eggs by 1,7 g, the exit of the egg mass on the middle and the initial laying-hens on 0,66 and 0,7 kg, the number of food eggs categories XL and L on 0,5 and 5.4%, compared with the control group of chickens, which was fed both in the morning and in the afternoon, a mix feed containing 3,5% calcium in the form of limestone thin and coarse grinding. Key words: laying-hens, mix feed, calcium, egg production, eggs mass, eggs quality.

Intermittent Lighting Improves the Efficiency of Artificial Insemination in Cage Housed Laying Hens Kavtarashvili A.Sh., Kolokolnikova T.N. Federal Scientific Center “All-Russian Research and Technological Poultry Institute” of Russian Academy of Sciences Omsk Agrarian Scientific Center Summary: The effects of different lighting regimes on the oviposition schedule, productive performance, and reproductive efficiency in cage housed laying hens of layer parental flock (Hisex White-R) were studied; the reasonable regime of artificial insemination (AI) under intermittent lighting is proposed. It was found that intermittent lighting regime 1L:4D:4L:1D:4L:10D compared to the constant lighting significantly alters oviposition schedule: under this regime 82.3% of all daily eggs were laid until 9 am (vs. 66.6% in control). This regime and AI at 10 am improved the productive and reproductive performance compared to control (constant lighting 16L:8D and AI at 12 am): mortality by 1.9%, egg production per initial hen by 3.8%, egg weight by 1.1%, percentage of eggs suitable for incubation by 1.9%, egg fertility by 0.9%, hatchability by 2.3%, hatch of chicks by 2.9%, feed conversion ratio (kg of feed per 10 eggs) by 5.3%, the expenses of electric energy for lighting (per 1000 eggs suitable for incubation) by 54.5%.
