Abstract

ABSTRACT. The research aimed to study the emulsion properties of the fortified synbiotic yoghurt fortification red dragon fruit peel extract (Hylocereus polyrhizus) and stevia as sweeteners. The research material is probiotic yoghurt, synbiotic fortified with red dragon fruit skin extract (Hylocereus polyrhizus) 20% made from 10% skim milk and yoghurt starter containing Lactobacillus bulgaricus and Streptococcus thermophilus (1:1), and the addition of 0.5% stevia to synbiotic. The research method was an experimental completely randomized design with treatment T1 = probiotic yoghurt, T2 = synbiotic yoghurt fortified red dragon fruit (Hylocereus polyrhizus) peel extract 20% and T3 = T2 + 0.5% stevia, with 3 replications (v/v). . The variables observed were emulsion activity, emulsion stability, turbidity, whiteness index (WI) and yellowness index (YI). The results showed that fortification of evaporated red dragon fruit peel extract (Hylocereus polyrhizus) and stevia sweetener gave a significant difference (P0.05) to the average emulsion activity, a very significant difference to the average of whiteness index and yellowish index (P0.01) and did not give a significant difference (P0.05) on the average of emulsion stability and turbidity of synbiotic yoghurt. It was concluded that 20% fortification of red dragon fruit skin (Hylocereus polyrhizus) and 0.5% stevia sweetener could improve the emulsion properties of synbiotic yoghurt.(Kajian yoghurt sinbiotik fortifikasi ekstrak kulit buah naga merah (Hylocereus polyrhizus) dan stevia terhadap sifat emulsi dan warna)ABSTRAK.

Abstract

ABSTRACT. Campylobacter merupakan salah satu bakteri yang terdapat dalam usus halus itik, yang dapat menurunkan performa dan menyebabkan penyakit yang bersifat zoonosis. Penularan kebanyakan terjadi melalui daging, tetapi belum ada yang memastikan bagaimana bakteri ini dapat berada pada daging, sehingga berbagai biokontrol diupayakan dalam menekan dan mencegah penularan Campylobacter. Tujuan penelitian ini untuk melihat efektivitas pemberian probiotik bakteri asam laktat, kunyit, dan gabungan keduanya dalam menekan keberadaan Campylobacter dalam usus halus, serta pengaruh pemberiannya terhadap performa itik lokal kerinci. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan materi 100 ekor itik lokal kerinci jantan, yang mendapat perlakuan kontrol (P0); pemberian Probio_FM (P1); pemberian larutan kunyit (P2), dan gabungan Probio_FM dan larutan kunyit (P3) dalam pakan, dengan masing-masing 5 ulangan. Hasil penelitian ini menunjukkan bahwa perlakuan yang diberikan tidak berpengaruh nyata (P0,05) terhadap performa, pH, jumlah bakteri asam laktat, dan jumlah Campylobacter pada jejunum dan ileum itik kerinci. Berdasarkan hasil penelitian, dapat disimpulkan bahwa pemberian Probi_FM, larutan kunyit, dan gabungan keduanya belum mampu menekan keberadaan Campylobacter dalam usus halus itik kerinci.(The effect of Probio FM and turmeric solution on performance and reducing Campylobacter in Kerinci local duck)ABSTRAK. Campylobacter is one of the bacteria found in the small intestine of ducks, which can reduce performance and cause zoonotic diseases. Transmission mostly occurs through meat, but no one has confirmed how this bacteria can be in the meat, so various biocontrols are treated to suppress and prevent Campylobacter transmission. This study intended to evaluate the effectiveness of lactic acid bacteria probiotics, turmeric, and their combination administrations in suppressing the presence of Campylobacter in the small intestine, as well as the effect of their administration on the performance of local kerinci ducks. The experiment used a completely randomized design (CRD) with 100 male local kerinci ducks, received control treatment (P0); administration of Probio_FM (P1); administration of turmeric solution (P2), and a combination of Probio_FM and turmeric solution (P3) in duck feed, with 5 replications respectively. The results showed that all treatments had no significant effect (P0.05) on the performance, pH, the number of lactic acid bacteria, and Campylobacter in the jejunum and ileum of kerinci ducks. It could be concluded that the administration of Probio_FM, turmeric solution, and their combination had not been able to suppress the presence of Campylobacter in the small intestine of kerinci ducks.

Abstract

ABSTRACT. Tujuan penelitian adalah mengkaji pengaruh lama fermentasi yang berbeda terhadap bakteri asam laktat, bakteri gram positif/negatif, Salmonella dan Escherichia coli litter broiler. Materi penelitian adalah litter broiler 1 kg, mineral mix, starter mix culture, garam, urea, molases masing-masing 60 gram, NaCl fisiologis 0,85%, alkohol 96%, media MRS, SSA, EMBA, aquades, kristal violet, iodine, dan safranin. Rancangan penelitian menggunakan rancangan acak lengkap (RAL) dengan 4 perlakuan dan 4 ulangan, dengan perlakuan litter broiler lama fermentasi yang berbeda T0 (0 hari), T1 (21 hari), T2 (42 hari) dan T3 (63 hari). Parameter penelitian yaitu total bakteri asam laktat (BAL), bakteri gram positif dan negatif, Salmonella, dan Escherichia coli (E. coli). Analisis data menggunakan uji ANOVA, dan jika terdapat perbedaan dilanjutkan dengan uji DMRT, dengan taraf signifikasi 5%. Hasil penelitian menunjukkan bahwa lama fermentasi yang berbeda memengaruhi total bakteri asam laktat (BAL) litter broiler fermentasi. Semakin lama durasi fermentasi, semakin tinggi total BAL litter broiler. Lama fermentasi yang berbeda tidak memengaruhi skor bakteri gram positif dan negatif litter broiler. Bakteri yang tumbuh pada litter broiler fermentasi berasal dari famili Staphylococcaceae (13,95%), Bacillaceae (32,57%), Streptococcaceae (23,26%), Saccharomycetaceae (6,98%), dan Pseudomonadaceae (23,26%). Bakteri gram positif litter broiler fermentasi berbentuk batang, tidak berspora, soliter, duplococcus, sedangkan bakteri gram negatif berbentuk batang dan soliter. Tidak ditemukan bakteri Salmonella sp. dan E. coli pada litter broiler fermentasi. Lama fermentasi yang berbeda mampu meningkatkan kualitas litter broiler, ditinjau dari total BAL. Litter broiler fermentasi berpotensi dijadikan sebagai alternatif bahan pakan, mengandung 13 gram positif dan 0 - 1 gram negatif, serta tidak ditemukan bakteri Salmonella sp. dan E. coli. Perlakuan yang direkomendasikan yaitu litter broiler dengan lama fermentasi 42 hari, dengan jumlah bakteri asam laktat sebanyak 2,4 log CFU/g.(Microbiological content of broiler litter at different times fermentation)ABSTRAK. The aim of the study was to examine the effect of different fermentation times on lactic acid bacteria, gram positive/negative bacteria, Salmonella and Escherichia coli litter broilers. The research material is broiler litter 1 kg, mineral mix, starter mix culture, salt, urea, molasses 60 grams each, 0.85% physiological NaCl, 96% alcohol, MRS media, SSA, EMBA, aquades, crystal violet, iodine , and safranin. The study design used a completely randomized design (CRD) with 4 treatments and 4 replications, with broiler litter treatments with different fermentation times T0 (0 days), T1 (21 days), T2 (42 days) and T3 (63 days). The research parameters were total lactic acid bacteria (LAB), gram positive and negative bacteria, Salmonella, and Escherichia coli (E. coli). Data analysis used the ANOVA test, and if there were differences, it was continued with the DMRT test, with a significance level of 5%. The results showed that different fermentation time affected the total lactic acid bacteria (LAB) in fermented broiler litter. The longer the duration of fermentation, the higher the total LAB of broiler litter. Different fermentation time did not affect the score of gram positive and negative bacteria in broiler litter. The bacteria growing in fermented broiler litter came from the family Staphylococcaceae (13.95%), Bacillaceae (32.57%), Streptococcaceae (23.26%), Saccharomycetaceae (6.98%), and Pseudomonadaceae (23.26%). Gram-positive bacteria fermented broiler litter are rod-shaped, non-sporing, solitary, duplococcus, while gram-negative bacteria are rod-shaped and solitary. No bacteria Salmonella sp and E. coli were found in fermented broiler litter. Different fermentation time can improve broiler litter quality, in terms of total LAB. Fermented broiler litter has the potential to be used as an alternative feed ingredient, containing 1-3 grams positive and 0-1 gram negative, and no Salmonella sp. and E. coli. The recommended treatment is broiler litter with a fermentation time of 42 days, with the number of lactic acid bacteria as much as 2.4 log CFU/g.

Dari hasil pengujian, diperoleh penambahan ekstrak kacang merah meningkatkan kecepatan pertumbuhan spesifik isolat bakteri asam laktat dan menurunkan pH medium sehingga, penggunaan ekstrak kacang merah dapat digunakan sebagai prebiotik yang dapat meningkatkan pertumbuhan bakteri asam laktat. Kecepatan pertumbuhan spesifik paling tinggi adalah isolat Bifidobacterium dalam medium MRS Broth dengan ekstrak kacang merah.(Specific growth rate of lactic acid bacteria with red bean extract (Phaseolus vulgaris L.) as a preliminary study of flavored yogurt production)ABSTRAK. Lactic acid bacteria are group of bacteria which ferment food carbohydrates and produce lactic acid as the main product of fermentation. This study aimed to determine the specific growth rate of lactic acid bacteria (Streptococcus thermophilus FNCC 0040 (ST), Lactobacillus bulgaricus FNCC 0041 (LB), Lactobacillus acidophilus FNCC 0051 (LA), Lactobacillus casei ALG.2.12 (LC ALG 2.12), Bifidobacterium ATCC 12746 (BF) as a preliminary study for the production of flavored yogurt. In this study, lactic acid bacteria was culture in two different medium, deMan Rogosa Sharpe (MRS) Broth and deMan Rogosa Sharpe (MRS) Broth with red bean extract. Optical density, lactic acid biomass and pH was measured during fermentation processed. The results showed that the addition of red bean extract increased the specific growth rate of lactic acid bacterial isolates and lowering the pH of the medium so that the use of red bean extract can be used as a prebiotic which can increase the growth of lactic acid bacteria. The highest specific growth rate was Bifidobacterium in MRS Broth medium with red bean extract.

Abstract

ABSTRACT. Genes differ in sequence, size, and functional domains among species. According to studies, STAT1 provides information on the rate of evolution that correlates with its function in the immune system. STAT1 is also considered a genetic marker for economic traits in mammals. Studying sequence comparison is an important issue in bioinformatic study and can explain phylogenetic. Therefore, this study aimed to identify the molecular phylogeny of river buffalo (Bubalus bubalis) and other mammals based on STAT1 gene sequences. This study used 7 STAT1 sequences from Ensembl (Bos grunniens, Bos indicus, Bos Mutus, Capra hircus, Cervus hanglu yarkandensis, Moschus moschiferus) and previous studies (Bubalus bubalis). The sequences were analyzed using the MEGA X 10.2.6 software to observe the nucleotide composition and the phylogeny (based on UPGMA). The adegenet package in the R 4.0.0 software is used to observe the STAT1 sequence dimensionally among mammals. The STAT1 sequence has almost similar diversity among the livestock of the same genus. Based on the STAT1 sequence, Bubalus bubalis has closer genetic proximity to the genus Bos than to another genus. In conclusion, we found STAT1 is more dynamic in evolution and more conserved and found in the similar related genus.(Filogeni kerbau Indonesia dibandingkan mamalia lain berdasarkan runutan nukleotida gen STAT1)ABSTRAK. Gen berbeda dalam urutan, ukuran, dan domain fungsional di antara spesies. Menurut penelitian sebelumnya, STAT1 memberikan informasi tentang laju evolusi yang berkorelasi dengan fungsinya dalam sistem kekebalan. STAT1 juga dianggap sebagai penanda genetik untuk sifat bernilai ekonomi pada mamalia. Studi perbandingan urutan merupakan isu penting dalam studi bioinformatika dan dapat menjelaskan filogenetik. Oleh karena itu, penelitian ini bertujuan untuk mengidentifikasi filogeni molekuler kerbau sungai (Bubalus bubalis) dan spesies mamalia lain berdasarkan sekuens gen STAT1. Penelitian ini menggunakan 7 sekuen STAT1 yang diambil dari Ensembl (Bos grunniens, Bos indicus, Bos mutus, Capra hircus, Cervus hanglu yarkandensis, Moschus moschiferus) dan penelitian sebelumnya (Bubalus bubalis). Sekuen dianalisis menggunakan program MEGA X 10.2.6 untuk melihat komposisi nukleotida dan filogeni (berdasarkan UPGMA). Adegenet package dalam program R 4.0.0 digunakan untuk mengamati urutan STAT1 secara dimensional diantara mamalia. Sekuen STAT1 memiliki keragaman yang hampir sama di antara ternak dari genus yang sama. Berdasarkan sekuen STAT1, Bubalus bubalis memiliki jarak genetik yang lebih dekat dengan genus Bos dibandingkan dengan genus lainnya. Sebagai kesimpulan, kami menemukan STAT1 lebih dinamis dalam evolusi dan lebih terkonservasi serta ditemukan dalam genus terkait yang serupa.

Abstract

ABSTRACT. Penelitian ini bertujuan untuk mengevaluasi pengaruh substitusi hijauan dengan silase daun ubi kayu (SDUK) dan konsentrat dengan hay ubi kayu difermentasi ragi (Habira) terhadap produksi susu, kualitas susu, dan efisiensi ekonomi sapi perah. Materi yang digunakan adalah lima (5) ekor sapi Friesian Holstein (FH) periode laktasi kedua (6611 hari) dengan bobot badan 387,66,8 kg diberi perlakuan pakan dalam Rancangan Bujur Sangkar Latin 5 x 5. Perlakuannya adalah T0 (hijauan 60% + 20% konsentrat + 20% ampas tahu), T1 (hijauan 40% + 20% SDUK + 20% konsentrat + 20% ampas tahu), T2 (hijauan 40% + 20% SDUK + 15%. konsentrat + 20% ampas tahu + 5% Habira), T3 (40% hijauan + 20% SDUK + 15% konsentrat + 20% ampas tahu + 10% Habira) dan T4 (60% hijauan + 10% konsentrat + 20% limbah tahu + 10% Habira). Variabel yang diukur adalah indeks suhu kelembapan (THI), konsumsi pakan, produksi susu, kualitas susu, hubungan konsumsi protein dan total nutrien tercerna/total digestible nutrient (TDN) dengan produksi susu serta efisiensi pakan dan ekonomi. Hasil penelitian menunjukkan bahwa nilai THI yang diperoleh mengindikasikan sapi perah mengalami cekaman panas. Perlakuan T1, T2, T3 dan T4 berbeda nyata (P0,05) dengan T0 dalam konsumsi nutrisi dan produksi susu, sedangkan komposisi susu tidak berbeda nyata antar perlakuan. Konsumsi protein dan TDN pakan memiliki hubungan linier dengan produksi susu (P0,05). Tidak ada perbedaan signifikan (P0,05) dalam efisiensi pakan dan ekonomis. Dapat disimpulkan SDUK dan Habira merupakan pengganti hijauan dan konsentrat yang baik untuk sapi perah laktasi.(Effect of forage and concentrate substitution with cassava leaves silage and cassava hay on milk production and milk composition of Friesian Holstein dairy cows)ABSTRAK. This study aimed to evaluate the effect of forage replacement by cassava leaves silage (CLS) and commercial concentrate by yeast fermented cassava hay (Yefecah) on the production and quality of milk and economic evaluation. Five, early on the second lactation cycle (6611 day in milk) Holstein Friesian cows were randomly assigned to a 5 (treatments) x 5 (replications). Treatments were T0 (60% forage + 20% concentrate + 20% tofu waste), T1 (40% forage + 20% CLS + 20 % concentrate + 20% tofu waste), T2 (40% forage + 20 % CLS + 15% concentrate + 20% tofu waste + 5% Yefecah), T3 (40% forage + 20 % CLS + 15% concentrate + 20% tofu waste + 10% Yefecah) and T4 (60% forage + 10% concentrate + 20% tofu waste + 10% Yefecah). Variables measured were temperature-humidity index (THI), feed intake, milk production, milk composition, interrelationship crude protein (CP) and total digestible nutrient (TDN) supply to milk production, and economic factors. The Result shows that T1, T2, T3, and T4 were significantly (P0.05) from T0 on nutrients intake and milk production. Whilst, the treatments were not significant (P0.05) affect to 4% fat corrected milk (FCM) and milk quality with T2 and T3 obtained the best value. The variables of CP and TDN intake have a positive relationship to milk production (P0.05). There were no significant differences in (P0.05) in feed and economical efficiency. It could be concluded that cassava foliage silage and yefecah were the good replacement of forage and concentrate for dairy cows.

Variables measured were feeding behavior and digestibility of DM and organic matter (OM). The results showed that cattle breed had a significant effect (P0.05) on eating rate in the afternoon, duration of daytime, nighttime and one-day meals, DM and OM digestibility. However, there was no significant effect (P0.05) on eating rate in the morning; frequency of daytime, nighttime, and one-day meals and rumination; spent time of daytime, nighttime, and one-day rumination. In conclusion, there are similarities and differences in feeding behavior, DM and OM digestibility among local cattle breeds, and digestibility of dry matter and organic matter of SO was lower than other cattles.

Abstract

ABSTRACT. Penelitian ini bertujuan untuk mengestimasi parameter genetik (heritabilitas, korelasi genetik) dan nilai pemuliaan serta menggunakan parameter-parameter tersebut untuk mengestimasi respon seleksi dan respon seleksi sifat berkorelasi untuk bobot lahir dan bobot sapih kambing Saburai jantan. Data bobot lahir dan bobot sapih 90 cempe jantan kambing Saburai (data dari tahun 2017-2018) yang dihasilkan dari sembilan ekor pejantan dan 45 ekor induk digunakan dalam penelitian ini. Heritabilitas, korelasi genetik dan fenotipik diestimasi menggunakan data saudara tiri sebapak. Hasil penelitian menunjukkan bahwa nilai heritabilitas estimasi untuk bobot lahir dan bobot sapih adalah termasuk kategori sedang (masing-masing 0,300,08 dan 0,220,07). Korelasi genetik antara bobot lahir dan bobot sapih dikategorikan sebagai positif tinggi (0,420,06), sedangkan korelasi fenotip antara kedua sifat ini adalah 0,10 (rendah) dan korelasi lingkungan 0,56 (tinggi). Respon seleksi meningkat dengan meningkatnya intensitas seleksi, berkisar antara 0,11 kg sampai 0,28 kg untuk bobot lahir dan antara 0,60 kg sampai 1,54 kg untuk bobot sapih, pada proporsi seleksi antara 50% sampai 5%. Respon seleksi sifat-sifat berkorelasi yang diharapkan terhadap seleksi bobot lahir secara langsung berdampak pada bobot sapih berkisar antara 0,29 kg hingga 0,75 kg pada proporsi seleksi 50% sampai 5%. Heritabilitas sedang dan korelasi genetik yang positif antara bobot lahir dan bobot sapih menunjukkan bahwa seleksi untuk salah satu dari dua sifat ini bisa berhasil dan peningkatan bobot lahir akan meningkatkan bobot sapih kambing Saburai jantan juga. Seleksi tidak langsung yaitu seleksi bobot lahir akan berdampak pada respon seleksi bobot sapih yang lebih rendah dibandingkan dengan seleksi langsung terhadap bobot sapih.(Evaluasi genetik dan respon seleksi bobot lahir dan bobot sapih pada kambing Saburai jantan)ABSTRAK. This research aimed to estimate genetic parameters (heritability, genetic correlation) and breeding value and used these parameters to estimate selection responses and correlated response to selection of birth and weaning weight of male Saburai goats. Data of birth and weaning weight of ninety male Saburai kids (2017-2018) generated from nine bucks and 45 does were used in this study. Heritability, genetic and phenotypic correlation were estimated using paternal half-sib data. The results showed that heritability estimates for birth and weaning weight were moderate category (0.300.08 and 0.220.07, respectively). Genetic correlation between birth and weaning weight was categorized as a high positive value (0.420.06), while phenotype correlations between the two traits were 0.10 (low), and environmental correlations were 0.56 (high). Responses to selection increased with increasing selection intensity ranging from 0.11 kg to 0.28 kg and 0.60 kg to 1.54 kg for birth and weaning weight, respectively, at 50% to 5% selection proportion. The response of the selection of correlated traits expected to direct birth weight selection impacted on weaning weight ranged from 0.29 kg to 0.75 kg at a selection proportion of 50% to 5%. The moderate heritability and positive genetic correlation between birth and weaning weight suggested that selection for any of these two traits should be successful and improving birth weight will improve the weaning weight of male Saburai goats as well. However, indirect selection (birth weight selection) will impact on the lower response for weaning weight compared to direct selection for weaning weight.
