The quality of feed can be improved by fermenting feedstuffs and supplementing with feed additives. This study aims to determine the effect of supplementation of Lumbricus sp. extract in fermented feed on growth performance, body chemical composition, and milkfish hepatosomatic index. Milkfish with an initial weight of 17.80 ± 0.20 g head-1, rearing with a density of 20 fish per hapa net measuring 1 m3 by 24 pieces. Hapa net is installed in a pond with a water level of ± 60 cm. Research was design in completely randomized design with two factors. The first-factor was supplementation method, namely Lumbricus sp. which sprayed on feed and mixed with feed ingredients. The second factor was the dose of Lumbricus sp. extract, namely 0, 100, 200 and 300 mL kg-1 of feedstuffs. The fish was reared for 50 days and fed with 5% of fish biomass per day with feeding frequency of 3 times i.e., morning, afternoon and evening. The results showed that the supplementation Lumbricus sp. extract has no significant effect on all parameters (P>0,05).  However, the level dose of Lumbricus sp. extract supplementation in feed has a significantly effect (P<0.05) on absolute growth, relative growth, feed efficiency, and hepatosomatic index, but no significant effect (P>0,05) on survival and chemical composition of milkfish body. The best best of absolute growth (16.94±4.0 g), relative growth (48.71±5.77%), feed efficiency (40.74±10.3 %), and hepatosomatic index (1.5 ± 0.17) were found in the experiment of supplementation Lumbricus sp. extract mixed with feedstuffs at a dose of 300 mL kg1. The survival rate of milkfish was ranging from 68.33±29.3 to 91.,33±7.64%, while the body's chemical composition including protein levels, fat, ash, crude fiber, NFE / Nitrogen Free Extract, liver glycogen and muscle glycogen were 69.45±1.23 – 71.45±0.97%, 14.86±0.46 – 17.24±0.76%, 9.28±0.12 – 11.12±0.46%, 1.54±0.09 – 1.66 ± 0.13%, 1.33± 0.42 – 2.71±0.21%, 7,11±0,08 – 7,40±0,17mg g-1 and 6,13±0,44 – 6,45±0,40 mg g-1, respectively.

Abstract This study was conducted to investigate the effects of a direct-fed microbial (DFM) product (Bacillus subtilis strain DSM 32540) in weaned pigs challenged with K88 strain of Escherichia coli on growth performance and indicators of gut health. A total of 21 weaned pigs [initial body weight (BW) = 8.19 kg] were housed individually in pens and fed three diets (seven replicates per diet) for 21 d in a completely randomized design. The three diets were a corn-soybean meal-based basal diet without feed additives, a basal diet with 0.25% antibiotics (neo-Oxy 10-10; neomycin + oxytetracycline), or a basal diet with 0.05% DFM. All pigs were orally challenged with a subclinical dose (6.7 × 108 CFU/mL) of K88 strain of E. coli on day 3 of the study (3 d after weaning). Feed intake and BW data were collected on days 0, 3, 7, 14, and 21. Fecal scores were recorded daily. On day 21, pigs were sacrificed to determine various indicators of gut health. Supplementation of the basal diet with antibiotics or DFM did not affect the overall (days 0–21) growth performance of pigs. However, antibiotics or DFM supplementation increased (P = 0.010) gain:feed (G:F) of pigs during the post-E. coli challenge period (days 3–21) by 23% and 24%, respectively. The G:F for the DFM-supplemented diet did not differ from that for the antibiotics-supplemented diet. The frequency of diarrhea for pigs fed a diet with antibiotics or DFM tended to be lower (P = 0.071) than that of pigs fed the basal diet. The jejunal villous height (VH) and the VH to crypt depth ratio (VH:CD) were increased (P &lt; 0.001) by 33% and 35%, respectively, due to the inclusion of antibiotics in the basal diet and by 43% and 41%, respectively due to the inclusion of DFM in the basal diet. The VH and VH:CD for the DFM-supplemented diet were greater (P &lt; 0.05) than those for the antibiotics-supplemented diet. Ileal VH was increased (P &lt; 0.05) by 46% due to the inclusion of DFM in the basal diet. The empty weight of small intestine, cecum, or colon relative to live BW was unaffected by dietary antibiotics or DFM supplementation. In conclusion, the addition of DFM to the basal diet improved the feed efficiency of E. coli-challenged weaned pigs to a value similar to that of the antibiotics-supplemented diet and increased jejunal VH and VH:CD ratio to values greater than those for the antibiotics-supplemented diet. Thus, under E. coli challenge, the test DFM product may replace the use of antibiotics as a growth promoter in diets for weaned pigs to improve feed efficiency and gut integrity.

<p>The authors have investigated the effect of different levels guanidinoacetic acid in the diets of quails on their productivity and carcass quality. Experimental studies were carried out in the conditions of the problematic research laboratory of feed additives in the National University of Life and Environmental Sciences of Ukraine. Material for scientific and economic experience was quail of Pharaoh species of meat direction of productivity. The experiment was carried out by method of groups-analogues. Compound feed were fed in dry crumbled form. Young animals were fed in a group. The daily amount of compound feed was divided in two parts – morning and evening rations. The effect of using different levels of Guanidinoacetic Acid (GAA) in compound feed on productivity and carcass quality of young quails was studied. We have found that compound feed with the level of GАА 0.06% contributes to live body weight increase by 3.9 g and muscles of the pelvic limbs yield by 26.2%. At the same time, use of diets with a level of 0.12% of guanidine acetate increases live weight by 13.5 g, the absolute growth of 6.5 g, average daily growth by 0.9 g, a relative growth of 2%, the mass of carcass, semi-eviscerated carcass, and eviscerated carcass of 4.8, 4.9 and 4.3% correspondingly, slightly increases the mass of pectoral muscles by 9.1%, significantly increases the yield of muscles of the pelvic limbs by 36.4%, and reduces feed conversion by 5%. Poultry which was fed with 0.18% of GАА exceeded control of body weight by 12.2 g, the absolute growth by 4.4 g, average daily growth by 0.6 g, the relative growth by 1.1%, yield of muscles of the pelvic limbs by 36.4% and  had a lower feed conversion rate by 9.1%. During the study period the safety of livestock which was fed with GААvwas high and ranged from 90 to 96%.  It was established the perspective of further research, which is to examine the impact of Guanidinoacetic Acid on the egg production of egg-laying quails, morphological and chemical composition of eggs and  their hatching  quality.</p>

Aims: Growth performance and gut morphological response of broiler chickens fed moist fermented diets with the inclusion of probiotics or/and organic acids were evaluated in a 56 day feeding trial. Place and Duration of Study: Poultry unit of the Department of Agricultural Education, Federal College of Education, Abeokuta, Ogun State, Nigeria between February 2018 and April 2018 Methodology: Three hundred one-day old unsexed Abor Acre broilers were used for this study. They were randomly allotted to 5 dietary treatments with 6 replicates of 10 birds each. The experimental treatments were: Diet 1: Dry Unfermented Feed (DUF) - Probiotics (Pr) – Organic acids (Or), Diet 2: Moist Fermented Feed (MFF) – Pr – Or, Diet 3: MFF + Pr, Diet 4: MFF + Or, Diet 5: MFF + Pr + Or. The experiment was carried out using a completely randomized design. Results: The feed conversion ratio of broiler starters fed diet 5 (1.96) was significantly (P<.0001) better relative to those of birds fed other diets (2.27, 2.21, 2.14 and 2.13 respectively), while birds in treatment 1 (2.27) had significantly (P<.0001) poor feed conversion ratio. There were no significant (P>.05) differences in the feed conversion ratio of broiler finishers fed MFF with or without feed additives (2.68, 2.64, 2.55 and 2.55). However, the value of feed conversion ratio of birds fed DUF (3.04) was significantly (P=.05) the highest. The duodenal villus height to crypt depth ratio of broiler starters fed MFF+ Pr + Or (7.11) was significantly (P=.05) higher than those of birds fed other diets (2.70, 3.35, 3.98, 4.73 respectively). Conclusion: Although, feed fermentation enhanced gut morphological parameters which correlates improved growth performance of broiler chickens. The inclusion of probiotics (1g/kg) and organic acids (1g/kg) in the fermentation process further improved the growth indicators of broiler chickens used in this study.

This study was performed to determine the effects of the extracts of two alternative antimicrobial agents that do not harm the ecosystem (rosemary, Rosmarinus officinalis and aloe vera, Aloe barbadensis) when added to the feed of tilapia (Oreochromis niloticus) on the growth performance, proximate composition, and biometric characteristics. Rosemary extract was added to the experimental diet in ratios of 0.1%, 0.25%, and 0.5% while aloe vera extract was added to the experimental diet in ratios of 0.5%, 1%, and 2.5%. After 90 days of the feeding trial, no change was seen in the weight increase, specific growth rate, feed conversion ratio, condition factor, hepatosomatic index, or viscerosomatic index of the tilapia. The fact that proximate analyses did not differ between groups showed that the plant extracts did not adversely affect the health status of tilapia in the ratios used in this study. As a result, the addition of 0.1%, 0.25%, and 0.5% rosemary extract and the addition of 0.5%, 1%, and 2.5% aloe vera extract to tilapia feeds did not cause changes in the growth performance, biometric indexes, or chemical composition findings of the fish meat.
