Aim: This study aimed to determine the use of probiotics Bifidobacterium spp. and Lactobacillus casei as alternative antibiotic growth promoters (AGPs) to improve growth performance and business analysis. Materials and Methods: This study used a completely randomized factorial design. The first factor was the time of administration (1, 2, 3, and 4 weeks) and the second was the use of probiotics (control without probiotics; 0.1% AGP and 0.5% Bifidobacterium spp. + 0.25% L. casei). One hundred and eighty laying hens (Lohmann strain), of 30 weeks old, were divided into 12 treatment groups, composed of five replicates, each consisting of three laying hens. Results: The results showed that using 0.5% Bifidobacterium spp. + 0.25% L. casei in weeks 1 and 2 showed the lowest feed intake (FI) (112.11-112.19 g/day), the highest egg weight (60.28 g) in the 1st week, the lowest feed conversion ratio (FCR) (2.21-2.23), and highest feed efficiency (44.75-45.25%) for 3-4 weeks, and the highest hen-day production (86.66-86.90%) for 3-4 weeks and the most profitable business analysis (IDR. 30,353). Conclusion: Based on the results, it can be concluded that the addition of 0.5% Bifidobacterium spp. + 25% L. casei probiotics can be used as a substitute for AGP; it can reduce the FI and FCR, increasing egg weight, feed efficiency, and hen-day production, as well as illustrating the results of the most profitable business analysis.
This study was the first to combine the addition of antioxidants to a skim milk–egg yolk (SM–EY) extender and different equilibration periods to obtain higher quality post-thawed Kacang buck semen. This study aimed to determine the effects of green tea extract (GTE) on the quality of frozen Kacang goat sperm equilibrated for one and two hours. The pool of Kacang buck ejaculate was equally divided into four portions and was diluted in an SM–EY extender that contained four doses of 0, 0.05, 0.10, and 0.15 mg of GTE/100 mL for T0, T1, T2, and T3 groups, respectively. The aliquots were treated for an equilibration period of 1–2 h before further processing as frozen semen. Post-thawed semen quality was evaluated for sperm quality. The Sanger method was used for DNA sequencing, and the amino acid sequence was read using MEGA v.7.0. The post-thawed semen of the T2 group that was equilibrated for one hour had the highest semen quality. Pre-freezing motility had the highest determination coefficient compared to post-thawed sperm motility. This study is the first to report amino acid mutation due to freeze–thawing. The frequency of amino acid mutations revealed that T2 was the least mutated amino acid. Glycine, valine, leucine, serine, and asparagine strongly correlated to post-thawed sperm motility. It can be concluded that a combination of 0.1 mg GTE/100 mL extender as an antioxidant and one-hour equilibration period resulted in the best post-thawed Kacang buck semen quality.
Background and Objectives: An experiment was designed to determine the effect of using lactic acid bacteria as alternative antibiotic growth promoters on external and internal quality of egg’s Coturnix coturnix japonica. Materials and Methods: Coturnix coturnix japonica (n=240, 14 weeks of age) were randomly distributed into six treatment groups. The treatments were P0 (free antibiotic feed), P1 (free antibiotic feed with 1 gram antibiotic growth promoters (AGP)/100kg feed), P2 (free antibiotic feed with 5 gram probiotic/100kg feed), P3 (free antibiotic feed with 10 grams probiotic/100kg feed), P4 (free antibiotic feed with 5 gram probiotic/200L drinking water), and P5 (free antibiotic feed with 10 gram probiotic/200L drinking water). Probiotic contained Lactobacillus casei (L. casei) and Lactobacillus rhamnosus (L. rhamnosus) culture (1.2 x 108 CFU/gram). To assess the quality parameters, twenty eggs were randomly collected from each treatment at the end of the experimental period, and the data were analysed using one way Anova. Results: Results of the external quality indicated that egg’s weight, length, and width, along with the shell weight and thickness were significantly different (P<0.05) after treatment. Likewise, the results of internal egg quality indicated that yolk color, height, width, and length, together with the albumen height, width, length, index and haugh unit were significantly different (P <0.05) after treatment. Conclusion: It was concluded from this research that dietary supplementation with probiotic which contains L. casei and L. rhamnosus could be used in laying Japanese quail with benefit on external and internal egg quality.
Asian white shrimp or can be called vannamei shrimp has the Latin name Litopenaeus vannamei has native habitat in coastal waters and American sea waters. This research was carried out in September 2018 in the Asian white shrimp farming business unit Tanjung Putih Village Sepulu District Bangkalan District and in Penatar Sewu Village Tanggulangin District Sidoarjo Regency. This study population used 3 pond plots in Asian white shrimp culture in Tanjung Putih Village, Sepulu District, Bangkalan District and in Penatar Sewu Village Tanggulangin District Sidoarjo Regency. Sample size is determined from the amount of shrimp fry capacity stocked. The sampling technique was carried out by researchers by following activities in the field, census and visiting respondents directly on the farm or in the farmer's group home to obtain the information and data needed. The results showed that the best feed management was obtained the best results on the 4 sample ponds in Sidoarjo with an average final weight growth rate of 9.73 grams at the first partial harvest, 83% Feed Efficiency, and a 90% survival rate. As for the lowest feed management results obtained in sample ponds 1 Bangkalan with a yield of 6.98% growth, feed efficiency by 71% and survival rate of 86%. As for the results of the analysis of vannamei shrimp aquaculture business at different locations in Bangkalan and Sidoarjo districts, it was concluded that the best Production BEP was obtained in Sidoarjo's 4 sample ponds, amounting to 1427 kg.

The conclusion of the best feed management and business analysis results is on the sidoajo sample ponds, the sidoarjo sample shows decent and efficient results.
The purpose of this study was to determine the use of probiotics Lactobacillus acidophilus and Bifidobacterium sp on feed consumption and Hen Day Production (HDP), layer was infected with Escherichia coli. About 120 layers at 25 weeks of age were randomized into six treatments. The treatment consisted of factors a (infection and non-infection Escherichia coli) and factor b (basal feed, AGP and probiotics). The results of the study gave probiotics an effect (p <0.05) on feed consumption, HDP and egg weight. Infection factors have an effect (p <0.05) on HDP but have no effect (p> 0.05) on feed consumption and egg weight. There was interactions between probiotic and infection factors (p <0.05) on HDP and egg weight but there was no interaction (p> 0.05) between probiotic and infection factors on feed consumption. The highest feed consumption was found in the treatment of infectious probiotics is 114.7g, the highest HDP was treated with non-infectious probiotics is 98.6%, the highest egg weight was treated with non-infectious probiotics is 60.5 g. It could be concluded that the administration of probiotics can produce good production performance and high profits.

Black Soldier Fly Larvae (BSFL) is an alternative protein source for livestock. This research aimed to know the effectiveness of BSFL for commercial feed substitution, related to production, productivity, and profitability in quail farm. This study used 80 quails which divided into 4 groups and each group consist of 20 quails. The treatments contained BSFL substitution with different composition, control group (P0) was given 100% commercial feed, (P1) was given a 5% BSFL substitution, (P2) was given a 10% BSFL substitution and (P3) was given a 20% BSFL substitution. Contribution margin (CM) analysis was used to determine the yields of the groups in this study. Results showed that the highest feed consumption rate is in P3, production (egg in total and weight), productivity and yields in P3 is the highest, although there's no difference between P0, P2 and P3 based on the analysis MANOVA. BSFL substitution at 20% is recommended to the farmers to increase profits.
