Judul: The Percentage of Internal Organs Weight of Broilers give The Suplementation Probiotics (Bacillus coagulans strain D3372) in Feed
Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh pemberian probiotik terhadap persentase berat organ dalam serta persentase panjang organ dalam ayam broiler yang dipelihara selama 35 hari. Probiotik yang digunakan adalah Bacillus coagulans strain D3372 berbentuk tepung yang ditambahkan dalam pakan. Penelitian ini menggunakan 600 ekor ayam berumur 1 hari yang dipelihara hingga umur 35 hari dengan 4 perlakuan dan 5 ulangan, setiap ulangan terdiri atas 30 ekor ayam. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL). Perlakuan yang digunakan adalah P0: Tanpa probiotik (pakan basal), P1: Pakan Basal + Probiotik 105 cfu g-1, P2: Pakan basal + probiotik 106 cfu g-1. P3: Pakam basal + Probiotik 107 cfu g-1. Peubah yang diamati adalah bobot organ dalam, bobot organ pencernaan serta panjang saluran pencernaan. Data dianalisis dengan ANOVA, jika pada analisi ANOVA didapatkan hasil yang berbeda nyata (P<0,05) , maka dilanjutkan dengan uji Duncan. Hasil penelitian menunjukan penambahan B. coagulans strain D3372 tidak menunjukkan pengaruh nyata (P>0,05) terhadap bobot hati, bobot jantung, bobot limfa, bobot empedu, bobot gizzard, bobot dan panjang relatif usus halus, bobot dan panjang relaif sekum serta bobot dan panjang relatif kolon. Penambahan probiotik B. coagulans strain D3372 107 cfu g-1 meunjukan pengaruh nyata terhadap penigkatkan persentase bobot pankreas. Pemberian Bacillus coagulans strain D3372 yang ditambahkan dalam pakan belum efektif mengoptimalkan fungsi organ dalam. Kata kunci: ayam broiler, Bacillus coagulans strain D3372, persentase organ dalam, probiotik., The experiment was aimed to study the effect of feeding supplementation of probitoc bacillus coagulans strain D3372 on the percentage of internal organ that have been .This study used 600 day old chick (DOC) broilers were reared up to 35-days-old with 4 treatments and 5 replication, each replication consisted of 30 boilers. This study was cinducted using Completely Randomized Design. The treatments diets containing different level of Probiotic B. coagullans strains D3372 (P0: without probiotic, P1: probiotic with level 105 cfu g-1, P2: probiotic with level 106 cfu g-1, P3: probiotic with level 107 cfu g-1). Parameters observed were weight of internal organs and intestinal organ and length of intestinal tract. Data from completely randomized design were analyzed with ANOVA. The results showed that the addition of B. coagulans strain D3372 showed no significant effect (P>0,05) on liver weight, heart weight, spleen weight, bile weight, gizzard weight, weight and length of small intestine, weight and relative length of cecum and weight and length relative of colon. The addition of probiotic B. coagulans strain D3372 107 cfu g-1 showed a significant effect on increasing the percentage of pancreatic weight. The addition of Bacillus coagulans strain D3372 in feed did not have a negative effect on internal organs.

Judul: Evaluation of Probiotic Combination Supplementation in the Diet on Giblet and Digestive Tract Weight of Broiler Chickens
Abstrak: Penelitian ini bertujuan mengevaluasi pemberian kombinasi probiotik Lactococcus lactis dan Bacillus licheniformis dalam ransum terhadap bobot organ dalam dan saluran pencernaan ayam broiler. Percobaan ini menggunakan 300 ekor ayam broiler strain Cobb dengan Rancangan Acak Lengkap (RAL) yang terdiri dari 3 perlakuan dan 5 ulangan. Perlakuan terdiri dari P1 = Ransum dengan pemberian 0,1% plasebo CaCO3 (kontrol), P2 = Ransum dengan pemberian 0,1% kombinasi probiotik Lactococcus lactis dan Bacillus lichenimorfis populasi 105 CFU g-1 pakan, dan P3 = Ransum dengan pemberian 0,1% kombinasi probiotik Lactococcus lactis dan Bacillus lichenimorfis populasi 106 CFU g-1 pakan. Peubah yang diamati yaitu persentase bobot dan panjang relatif saluran pencernaan, bobot organ dalam, dan organ imunitas. Hasil penelitian menunjukkan bahwa kombinasi probiotik Lactoccoccus lactis dan Bacillus licheniformis populasi 106 CFU g-1 dalam ransum berpengaruh nyata (P, This study aimed to evaluate the supplementation of a combination of Lactococcus lactis and Bacillus licheniformis probiotics in the diet on the weight of giblet and the digestive tract of broiler chickens. The experiment used 300 Cobb strain broiler chickens with a Completely Randomized Design (CRD) consisting of 3 treatments and 5 replications. The treatments consisted P1 Diet with 0.1% placebo CaCO3 (control), P2 Diet with 0.1% combination of Lactococcus lactis and Bacillus licheniformis probiotics at a population of 105 CFU g¹, and P3 = Diet with 0.1% combination of Lactococcus lactis and Bacillus licheniformis probiotics at a population of 106 CFU g¹. Variables observed were the percentage of the weight and relative length of the digestive tract, giblet and immune organs weight. The results showed that the combination of probiotics Lactococcus lactis and Bacillus licheniformis with a population of 10 CFU g¹ in diet significantly (P<0.05) decreased kidney weight and cecum relative length, increased bile and thymus weight. The combination of probiotics Lactococcus lactis and Bacillus licheniformis with a population of 10 CFU g¹ in diet significantly (P<0.05) increased the weight of jejunum and ileum due to improved nutrient absorption facilitated by probiotics in the digestive tract. The conclusion of this study is the supplementation of a combination of Lactococcus lactis and Bacillus licheniformis probiotics with a population of 10 CFU g¹ in diet can improve the function of internal organs and the digestive tract, and enhance the immune response of broiler chickens.
