Use Of Fermented Feed Research Articles

The use of fermented feed containing black soldier fly (Hermetia illucens) and azolla sp on egg production and egg clutch in hybrid chickens

The purpose of the study is to investigate the effect of fermented feed containing black soldier fly and azolla meal on egg production and egg clutch. The research material used 20 female hybrid chickens and local feed ingredients. The research method was conducted experimentally using a Complete Randomized (RAL) with five (5) treatments and four (4) replications respectively. The feed treatments were P0 (100% feed control), P1 (90% basal feed + 5% black soldier fly + 5% azolla), P2 (85% basal feed + 5% black soldier fly + 10% azolla), P3 (85% basal feed + 10% black soldier fly + 5% azolla), P4 (80% basal feed + 10% black soldier fly + 10% azolla). The observed parameters included egg production, egg clutch, eggshell color, and thickness. The data obtained were analyzed using Analysis of Variance (ANOVA). The study found no significant effect on egg production, egg clutch, shell color, and thickness when feeding fermented black soldier fly and azolla at different levels. It was concluded that fermented feed containing 5-10% black soldier fly and 5-10% azolla did not negatively affect egg production and egg clutch in hybrid chickens.

The use of Fermented Feed on the Growth of Tilapia (Oreochromis niloticus): A Review

Feed is the most important factor that must be considered for fish growth. Feed is also an important factor and affects the survival and growth of fish. The growth of tilapia is very dependent on physical and chemical influences and their interactions. Tilapia fish are included in omnivorous fish or all-eating. These fish can breed with a variety of foods, both animals and plants. Tilapia when it is still in the form of seeds, its food is plankton and moss, while when it is an adult, it can be given additional food in the form of artificial feed. The purpose of this study was to find out how the use of fermented feed on the growth of tilapia and the addition of fermented doses of 2% to 6%. The method used is a descriptive exploratory method from various previous research literature, both from national journals and international journals: Research Gate, Directory of Open Access Journals and Google Scholar. Fermentation is microbial activity in food to produce the desired product. Microbes that are generally involved in fermentation are bacteria, yeast and mold. Fermentation will simplify the particles in the feed ingredients so that it will increase the nutritional value of the feed. The results of the addition of fermentation to feed greatly affect the growth of tilapia with research giving doses of 2 to 6% fermented products with the highest growth, FCR and survival.

Recent advances in fermented feeds towards improved broiler chicken performance, gastrointestinal tract microecology and immune responses: A review.

Previously, fermentation has been associated with methods that improve the nutritional value of unconventional feed ingredients for broilers. In recent decades, the fermentation process has been employed to produce functional feeds that have the potential to improve broiler gastrointestinal tract microecology, health and production performance. Some of the functional ingredients found in fermented feed include lactic acid bacteria (LAB), lactic acid and other organic acids, and appear to play major roles in determining the beneficial effects of fermented feed on broiler gut health and performance. Unlike the pig, the available literature on broiler fermented feed is still rather limited. This review describes recent advances in the use of fermented feed (on the basis of conventional and unconventional feed ingredients) in broilers. Similarly, this review also shows that additional research is necessary to exploit fermented feed as a viable food source in broiler nutrition.

The purpose of this public service activities is to help improve productivity and accelerate egg hatchability of eggs using appropriate technology incubator eggs that are expected to improve the economy of the people in the district of Malang apart from that application's use of fermented feed can improve the digestibility so that growth can be maximized. IbM's results show that community service is very enthusiastic partners with activities provided by the team, the use of egg incubators can improve hatchability of eggs in bulk to minimize the time the hatch and feed fermentation using Aspergillus orizae can increase the protein content of crude protein feed from 12.09 to 19 , 77 and lower crude fiber of 7.99 becomes 3.83, which improves the performance egg quality (larger size and eggshell color dark brown). A direct partner to practice the use of the incubator incubator capable hatch into chicks and want to practice the use of chicken feed fermentation.

KELIMPAHAN CHRYSOPHYTA PADA MEDIA BUDIDAYA IKAN NILA YANG DIBERI PAKAN FERMENTASI DENGAN PENAMBAHAN TEPUNG KULIT UBI KAYU DAN PROBIOTIK

Chrysophyta is also known as golden-yellow algae because of the yellow dominant pigment of carotene and xanthophyll. This study aimed to determine species richness and abundance of Chrysophyta in the Tilapia culture media which was fed with the addition of cassava peel flour and probiotic. The method applied in this study was the experimental method with 4 treatments, i.e.: the use of fermented feed with the addition of cassava peel flour (0%, 25%, 50%, and 75%) and probiotic in Tilapia culture media. Each treatment was replicated 4 times. Sampling was carried out 6 times at intervals of 2 weeks. The observed parameters were the main parameters, i.e.: the number of Chrysophyta species and individuals; and supporting parameters, i.e.: water temperature, pH, TDS, TSS, NO3, NO2, BOD5, DO, and total of phosphate. Species richness and abundance of Chrysophyta data were analyzed using cluster analysis based on Bray-Curtis similarity coefficient. The analysis continued with Similarity Percentages (SIMPER) analysis to determine the contribution of species to the similarity index in each group or to dissimilarity index amongst groups. The results showed that the species richness found in the Tilapia media culture which was fed with the addition of cassava peel flour and probiotic consist of 20 species belonging to a class namely Bacillariophyceae. Abundance of Chrysophyta obtained was ranged from 5.160-13.292 individuals/liter. The cluster analysis showed that Chrysophyta amongst treatments have a quite high similarity level (> 50%) was ranged between 65.56% -83.99%. Contributions of species which contribute the highest similarity index were Diatoma vulgare (49.80%), Navicula brachysira (70.50%) and Navicula platystoma (82%).

Fermented feed for laying hens: effects on egg production, egg quality, plumage condition and composition and activity of the intestinal microflora

1. An experiment with a total of 480 hens (Babcock) was carried out from 16 to 38 weeks of age to evaluate the suitability of wet fermented feed (feed water ratio, 1:1·2–1:1·4) for layers, taking aspects of nutrition and gastrointestinal health into consideration. The production performance, egg shell quality, plumage condition, litter dry matter (DM) content, as well as the composition and activity of the intestinal microbial flora were analysed. 2. Fermented feed was characterised by a high concentration of lactic acid (160–250 mmol/kg feed) and a moderate level of acetic acid (20–30 mmol/kg feed), high numbers of lactic acid bacteria (log 9–10 CFU/g feed) and a pH of approximately 4·5. Feed fermentation reduced the concentration of dietary sugar from 32·1 to 7·3 g/kg DM and the phytate bound phosphorus from 2·7 to 1·9 g/kg DM. 3. Fermented feed seemed to loose attractiveness for the birds quite rapidly, resulting in a more aggressive behaviour and a poorer plumage condition than in birds given dry feed. The use of fermented feed reduced the litter DM content. 4. During the experimental period, the body weight gain of hens receiving fermented feed was 80 g higher than of hens fed the dry mash. Presumably because of an extended adaptation time to the feed, the onset of lay occurred later when hens were fed on fermented feed, resulting in non-significantly reduced total egg production (75 vs. 82%). 5. There was no significant difference between groups with respect to the total egg mass production (g/d/hen, 42 and 45 for fermented feed and dry mash, respectively). Throughout the experimental period, the feed DM intake of hens fed with fermented feed was lower than that of hens receiving the dry mash (110 vs. 125 g). From week 26 to 37, fermented feed improved the feed conversion as compared with the dry mash (g feed DM/g egg mass, 2·28 vs. 2·53). 6. The use of fermented feed increased egg weight in the period from 34 to 37 weeks (61·4 vs. 60·0) and increased shell weight (g/100 g egg weight, 10·2 vs. 9·9) and shell stiffness (N/mm, 161 vs. 150) of eggs collected at 37 weeks. 7. The feeding of fermented feed increased intestinal health by acidification of the upper digestive tract, forming a natural barrier towards infection with acid sensitive pathogens, e.g. E. coli, Salmonella and Campylobacter. 8. It was concluded that fermented wet feed offers potential benefits for health and nutrition, but may become suitable for layers only after the practical problems related to this feeding form have been overcome. However, an early adaptation of the birds during the rearing period seems to be necessary.

Effect of fermented feed on shedding of Enterobacteriaceae by fattening pigs

Epidemiological studies showed that the use of fermented feed could significantly reduce Salmonella prevalence in pigs compared to the use of normal feed. Experimental challenge experiments with Salmonella have however never been conducted to reveal the efficacy of fermented feed in reducing Salmonella shedding and/or reducing the number of Salmonella-positive pigs. A longitudinal study was conducted to measure the effect of fermented feed, in particular of its components lactic acid and Lactobacillus plantarum, on gastrointestinal bacterial ecology ( Salmonella, Enterobacteriaceae, lactobacilli, volatile fatty acids (VFAs), pH). Seeder pigs were used as a mode for Salmonella transmission within a pig herd. Bacteriological measurements were performed in faeces of the pigs. The results showed that fermented feed affected/reduced the Enterobacteriaceae population in faeces of the pigs. No differences were found in the number of positive pigs infected or in the number of shedding with Salmonella serovar Typhimurium fed fermented feed and between the normal feed group. S. serovar Goldcoast could not establish an infection in the seeder pigs in the fermented feed group as well as in the normal feed group. The pH of the faeces in the fermented feed groups was significantly higher than the pH of the faeces of the normal feed groups. The role of the undissociated form of the faecal VFAs on the significantly lower Enterobacteriaceae number in faeces of the pigs of the fermented feed groups could not be demonstrated because of the significant higher pH in the faeces of the pigs fed fermented feed.

Mechanism ofSalmonella reduction in fermented pig feed

To protect consumers from Salmonella infection acquired through the consumption of pork meat, it is necessary to eradicate Salmonella from pork. In order to achieve this, the whole pork production chain should be free from Salmonella, including the pigs at the farm. In epidemiological studies it was concluded that the use of fermented feed plays a significant role in the reduction of Salmonella prevalence in pig farms. However, the mechanism of Salmonella reduction in fermented feed is not known. A controlled feed fermentation was performed using a pure culture of Lactobacillus plantarum. pH reduction, organic acid profiles and bacterial counts were determined. In L plantarum-fermented feed, lactic acid and acetic acid were produced and the pH dropped to a value below 4.0. Antimicrobial products (bacteriocins) could not be detected. The results showed that the produced lactic and acetic acid and the pH in the feed are responsible for Salmonella reduction in fermented feed. L plantarum did not show any other antimicrobial effect on Salmonella. © 2000 Society of Chemical Industry
