This research aims to analyze the management of raw materials procurement, management of supply chain, production performance, and also to analyze the internal and the external environmental conditions of banana chips agroindustries. This research was conducted in Sungai Langka Village of Pesawaran Regency. This location was selected purposively with consideration that Sungai Langka Village was the only village in Pesawaran Regency which was built by University of Lampung  as Village Laboratory that actively produce banana chips. The total respondents were 6 people consisting of one owner and one worker from each industry. Data were collected in December 2017 until January 2018. This research is using descriptive qualitative and descriptive quantitative methods. The results showed that banana chips agroindustries did not procure raw materials on time and exact amount.  However, management of supply chain and performance of banana chips agroindustries in Sungai Langka Village have been going well. The average productivity was 11.10 kg/working day and the average capacity was 78 percent.Key words: agroindustry, banana chips, environmental, and performance

An on-farm mono culture experiment was conducted for a period of four months from May to September 2014 to compare the growth and production of stinging catfish, Heteropneustes fossilis, at two different environmental conditions. Two locations were one in Gazipur Sadar (AEZ 28)and the other in Narsingdi Sadar (AEZ 9).At each location, there were five ponds of almost similar size and water depth. The stocking density was 500 fry per decimal for each location. Pre-stocking and post-stocking management were similar in both locations. There were considerable variations in most of the water and soil qualities between two locations. After four months of rearing, significantlyhigher (p<0.05) mean harvesting weight of H. fossilis (48.10±7.12 g) was observed in Narsingdi, as compared to that of Gazipur (23.18± 6.24 g).

Farm Animals

In the past few decades, farm animal health and welfare have been paid increasing concern worldwide. Farm animal health and welfare are generally assessed by the measurements of physical health, immune response, behavior, and physiological indicators. The gut microbiota has been reported to have a great influence on host phenotypes, possibly via the immune processes, neural functions, and endocrine pathways, thereby influencing host phenotypes. However, there are few reviews regarding farm animals’ health and welfare status concerning the gut microbiota. In this point of view, (1) we reviewed recent studies showing that gut microbiota (higher alpha diversity, beneficial composition, and positive functions) effectively influenced health characteristics, immunity, behaviors, and stress response in farm animals (such as pigs, chickens, and cows), which would provide a novel approach to measure and evaluate the health status and welfare of farm animals. In addition, fecal microbiota transplantation (FMT) as one of the methods can modulate the recipient individual’s gut microbiota to realize the expected phenotype. Further, (2) we highlighted the application of FMT on the improvement of the production performance, the reduction in disease and abnormal behavior, as well as the attenuation of stress in farm animals. It is concluded that the gut microbiota can be scientifically used to assess and improve the welfare of farm animals. Moreover, FMT may be a helpful strategy to reduce abnormal behavior and improve stress adaption, as well as the treatment of disease for farm animals. This review suggests that gut microbiota is a promising field to evaluate and improve animal welfare.

Abstract The aim of this study was to collect production data of Polish swine herds, with special emphasis on the production parameters in farrow to finish pig herds. Another goal was to determine differences in the production performance of swine herds with different sizes, various status with regard to biosecurity, and with different veterinary expenditure. For this purpose, questionnaire surveys were carried out in 96 polish farrow to finish pig herds. The data concerning production parameters (e.g. the number of pigs born per sow per year, litters per sow per year, pre- and post-weaning mortality), farm size (small, medium, large), management (all in-all out by room or building), veterinary expenditure (including medication) and the percentage of pigs under medical treatment, were collected. The data obtained in the present study indicate that in general, the efficiency of swine production in evaluated farms was relatively low. It was also found that in large swine farms the efficiency was better than that in small ones and that the proper biosecurity positively influenced the performance of the swine farms. However, only in 10.4% facilities, the biosecurity rules and methods, including the principle “all-in all-out”, were implemented and kept. It seems that inefficient swine production on the majority of Polish farms results from poor basic knowledge on pig production and understanding of fundamental economic rules of swine breeding.

AbstractDue to ban on using antibiotics in feed industry, awareness of using natural feed additives have led to a great demand. The interest of plants phenolic compounds as a potential natural antioxidant source has been considered in research community due to their predictable potential role as feed additives in poultry and swine production. However, the mode of action for their functional role and dosage recommendation in animal diets are still remain indistinct. Taking into account, the present review study highlights an outline about the mode of action of phenolic compound and their experimental uses in poultry and swine focusing on the growth performance, antioxidant function, immune function, antimicrobial role and overall health status, justified with the past findings till to date. Finally, the present review study concluded that supplementation of phenolic compounds as natural feed additives may have a role on the antioxidant, immunity, antimicrobial and overall production performance in poultry and swine.

Otoconia are microscopic geometric structures that cover the sensory epithelia of the utricle and saccule (gravitational receptors) of mammals, and the lagena macula of birds. The importance of otoconia for maintanance of the body balance is evidenced by the abnormal behavior of species with genetic defects of otolith. Although a few reports have dealt with otoconia formation, some basic questions remain unanswered. The chick embryo is desirable for studying otoconial formation because its inner ear structures are easily accessible, and its gestational period is short (21 days of incubation).The results described here are part of an intensive study intended to examine the morphogenesis of the otoconia in the chick embryo (Gallus- domesticus) inner ear. We used chick embryos from the 4th day of incubation until hatching, and examined the specimens with light (LM) and transmission electron microscopy (TEM). The embryos were decapitated, and fixed by immersion with 3% cold glutaraldehyde. The ears and their parts were dissected out under the microscope; no decalcification was used. For LM, the ears were embedded in JB-4 plastic, cut serially at 5 micra and stained with 0.2% toluidine blue and 0.1% basic fuchsin in 25% alcohol.

In recent years, with electron microscopes coming into wider use, their installation environments do not necessarily give their performance full play. Their environmental conditions include air-conditioners, magnetic fields, and vibrations. We report a jointly developed entirely new vibration isolator which is effective against the vibrations transmitted from the floor.Conventionally, large-sized vibration isolators which need the digging of a pit have been used. These vibration isolators, however, are large present problems of installation and maintenance because of their large-size.Thus, we intended to make a vibration isolator which1) eliminates the need for changing the installation room2) eliminates the need of maintenance and3) are compact in size and easily installable.
