Saat ini, udang Litopenaeus vannamei menjadi salah satu fokus komoditas ekspor yang dikembangkan oleh Kementerian Kelautan dan Perikanan untuk dapat terus ditingkatkan baik dalam jumlah produksi maupun nilai ekonomi yang dihasilkan. Untuk mendukung hal ini, intensifikasi sistem produksi, peningkatan efisiensi manajemen pakan dan penggunaan nutrisi yang mampu memenuhi kebutuhan spesifik udang Vannamei menjadi variabel produksi yang sangat penting untuk diperhatikan. Integrasi antara nutrisi dan sistem manajemen pakan yang baik diharapkan mampu meningkatkan performa pertumbuhan udang Vannamei dan resistensi udang terhadap infeksi patogen sehingga pada akhirnya akan dihasilkan nilai ekonomi yang lebih baik dan di saat yang bersamaan, mampu mempertahankan kualitas lingkungan melalui minimalisasi akumulasi limbah organik didalam media pemeliharaan.
Udang L. vannamei merupakan hewan omnivora yang hidup di dasar kolam dengan kapasitas yang sangat terbatas untuk menyimpan makanan dalam saluran pencernaan sehingga proses penyerapan nutrisi pada udang tergolong sangat lambat. Kondisi ini semakin diperparah apabila pengelolaan pakan dilakukan dengan tidak tepat sehingga kemungkinan terlarutnya bahan-bahan nutrient dalam pakan yang tidak segera dikonsumsi oleh udang semakin besar. Berdasarkan riset yang kami lakukan, pakan yang tidak langsung dikonsumsi selama lebih dari 30 menit akan menyebabkan rendahnya laju pertumbuhan dan meningkatkan rasio konversi pakan. Hal ini menunjukkan tentang pentingnya rancang bangun sistem manajemen pakan yang baik untuk mencegah leaching nutrisi dalam pakan dan juga meningkatkan efisiensi produksi. Pada artikel ini, hasil pengamatan tentang efektifitas pemberian pakan secara tradisional, penggunaan solar autofeeder, dan penggunaan sound-based feeding system, dimana pakan diberikan hanya pada saat udang merasa “lapar”, untuk menunjang laju pertumbuhan akan disajikan melalui penyertaan data pengamatan di tahun 2016, 2017 dan 2018.

This study evaluates the performance characteristics of Marshal strain broiler chicks (n = 180) fed Aspergillus niger treated Jatropha curcas kernel meals. Jatropha curcas kernels were subjected to five different processing methods, namely: Raw Defatted Fermented Meal (RDFM), Toasted Defatted Fermented Meal (TDFM), Cooked Defatted Fermented Meal (CDFM), Lye treated Defatted Fermented Meal (LDFM) and Sand roasted Defatted Fermented Meal (ZRFM) for a 21 day period in a completely randomized design model. Six (6) dietary treatments were formulated such that Diet 1 contained 0% Jatropha curcas kernel Meal while diets 2, 3, 4, 5 and 6 contained 10.33% (one-third replacement of soybean meal) inclusion level of RDFM, TDFM, CDFM, LDFM and ZDFM. It was observed that Fermentation had little effect on the CP though there was an increase in RDFM, meanwhile the antinutrients increased except for phorbol esters. The improved average daily feed intake, average daily gain and mortality in birds fed the dietary treatments could be attributed to the reduced phorbol esters during fermentation while the varying levels of hepatic degeneration can be attributed to the residual antinutrients in the meals. It can be concluded that the birds cannot tolerate the 10.33% inclusion level.

Two experiments were carried out to determine the effects of diets containing fermented and amino acid (AA)-supplemented malted sorghum sprout (MSP) on performance, nutrient utilisation and feed cost analysis of growing pigs. In experiment 1 (digestibility trial), 12 pigs were individually housed in metabolic crates, equipped with feeding and watering troughs which also allow for separate collection of faeces and urine. Data collection lasted for 7 days during which feed intake and faecal output were weighed, with daily storage of collected faeces at −4°C. Four diets, a basal diet, basal plus malted sorghum sprout (B +MSP), basal plus fermented malted sorghum sprout (B+ FMSP) and basal plus amino acids plus malted sorghum sprout (B+AA+MSP), were tested. Samples of test ingredients, feed and faeces were analysed for their gross energy and proximate compositions. In experiment 2, 18 weaner pigs were used in a completely randomised design for 63 days to determine the performance and cost analysis of feeding malted sorghum sprout at 0, 100 and 200 g/kg in pig's diet, six pigs per diet with each pig representing a replicate. Daily feed intake and weekly weight gain were determined. The prevailing cost of each feed ingredient was used to compute the feed cost and, subsequently, the feed cost analysis. Results of digestibility trial showed that there was no difference in the utilisation of the chemical constituents of B+MSP and B+AA+MSP diets, which were also similar to the basal diet, except the crude protein (CP) in amino acid-supplemented malted sorghum sprout diet, which was lower compared to the basal diet. B+FMSP was lower (P<0.05) in the digestibility of dry matter, organic matter and CP compared to the basal diet. The digestible energy (DE) and the fraction of gross energy utilised as DE of each diet also were not affected by fermentation and supplementation with AA. In experiment 2, the levels of MSP used did not affect (P>0.05) the performance and feed cost indices measured. It was concluded that MSP can be used in growing pig's diet, without the need for fermentation and AA supplementation, at 200 g/kg level with no adverse effect on the nutritive value of the diet.

(AA)-supplemented malted sorghum sprout (MSP) on performance, nutrient utilisation and feed cost analysis of
growing pigs. In experiment 1 (digestibility trial), 12 pigs
were individually housed in metabolic crates, equipped with feeding and watering troughs which also allow for separate collection of faeces and urine. Data collection lasted for 7 days during which feed intake and faecal output were weighed, with daily storage of collected faeces at −4 °C.
