The material used was 166 heads of white Brahman cross steer, with an average slaughter weight of 424.40–35.86 kg, and the range of age was 1.5–2 years. Sample of this study was Brahman cross steers with 83 heads large framed and 83 heads medium framed. The study method used was case studies. The obtained data was analyzed with independent t-tests, simple linear regression, and correlation. Results showed that frame size was highly significant (P&lt;0.01) in slaughterweight. The average slaughterweight on the medium frame was 415.82 ± 35.98 kg, and the medium frame was 432.98 ± 33.83 kg. Frame size is also highly significant (P&lt;0.05) in carcass weight. The correlation between slaughter weight and carcass weight was very close, with a correlation coefficient of 0.87 on medium frames and 0.90 on large frames. This study concluded that Brahman cross steers with large frames resulted in slaughter weight and carcass weight higher than medium frames but produced the same carcass percentage.</p> Roviki Rafsanjani Rafsanjani, Hary Nugroho, Trinil susilawati Copyright (c) 2023 Jurnal Agro Veteriner http://creativecommons.org/licenses/by-nc-sa/4.0 https://e-journal.unair.ac.id/agrovet/article/view/49259 Fri, 01 Dec 2023 00:00:00 +0700 Probiotics Addition Potential to Increase Body Weight, Feed Consumption and Feed Conversion on Pre-Layer Laying Hens https://e-journal.unair.ac.id/agrovet/article/view/51392 <p>Probiotics are all forms of microbial cell preparations or components of microbial cells that have a beneficial effect on the health and life of the host. Some feed additives such as the Antibiotic Growth Promoter (AGP) hormone have been banned. Therefore, nowadays, probiotics are often used as additives to replace antibiotics. The probiotics that are widely used are lactic acid bacteria because they can increase the efficiency of digestion and absorption of nutrients. The purpose of this study was to determine the effect of giving probiotics a combination of <em>Bacillus coagulans</em> and <em>Bacillus subtilis </em>with doses of 2 ml, 4 ml, and 6 ml/head/day orally on weight gain, feed consumption, and decreased feed conversion of laying hens. This study was conducted for 2 weeks using pre layer chickens aged 21 weeks to 23 weeks old as many as 24 chickens, randomized into 4 treatments with 6 replications with P0 as control, P1 = 2 ml, P2 = 4 ml, and P3 = 6 ml. The probiotic used is a combination of probiotics Bacillus coagulans and Bacillus subtilis with a concentration of 1x107 CFU/ml in liquid.&nbsp;</p> Sukmawati Lailatul Jannah, Mirni Lamid, Mohammad Sukmanadi, Mohammad Anam Al Arif, Sri Hidanah, Sri Chusniati Copyright (c) 2023 Jurnal Agro Veteriner http://creativecommons.org/licenses/by-nc-sa/4.0 https://e-journal.unair.ac.id/agrovet/article/view/51392 Fri, 01 Dec 2023 00:00:00 +0700 White Kupang Flour (Corbula faba hinds), Fish Meal and Coconut Oil Usage on the Broilers Carcass Percentage and Abdominal Fat https://e-journal.unair.ac.id/agrovet/article/view/51393 <p>This study was conducted to determine the effect of using white mussel flour fish flour and coconut oil on carcass percentage and abdominal fat percentage in broilers. This study used a completely randomized design consist 4 treatments and 5 replications. The study used DOC ( Day Old Chick ) with the strain Lohman MB 202 Platinum for 20 animals . The treatment in this study was ration without using white mussel flour (P0), ration using 10% white mussel flour (P1), ration using 12.5% white mussel flour (P2), ration using 15% white mussel flour (P3). Variables observed were carcass percentage and abdominal fat percentage. Data were analyzed by Analysis of Variance (ANOVA) if there is a significant effect then proceed with Duncan’s Multiple range test significance level of 5%. The results of the analysis showed that P3 showed a significant difference with the control treatment (P0) and treatment P1 (p&lt;0.05). The best broiler carcass percentage was in treatment P3 (76.02%) and P2 (74.7%) while the lowest was in treatment P0 (71.20%). The results of Duncan's test on the percentage of abdominal fat showed that the control treatment (P0), treatment P1, treatment P2, and treatment P3 were not significantly different (p&gt; 0.05).&nbsp;</p> Virgy Dzakina Fahrezy, Mirni Lamid, Setiawan Koesdarto, Emy Koestanti Sabdoningrum, Widya Paramita Lokapirnasari, Sunaryo Hadi Warsito Copyright (c) 2023 Jurnal Agro Veteriner http://creativecommons.org/licenses/by-nc-sa/4.0 https://e-journal.unair.ac.id/agrovet/article/view/51393 Fri, 01 Dec 2023 00:00:00 +0700 Effectiveness of the California Mastitis Test (CMT), Reductase Test, and Alcohol Test for Dairy Cows Subclinical Mastitis Detection https://e-journal.unair.ac.id/agrovet/article/view/51443 <p>Mastitis is an inflammation of the mammary glands caused by pathogenic bacteria Mastitis divided into 2 types, clinical mastitis which has symptoms of swelling and changes in the shape of the mammary gland, while subclinical mastitis does not indicate clear symptoms. Subclinical mastitis is a very high case in Indonesia, around 97-98%, while clinical mastitis is 2-3%. Effectiveness of the california mastitis test (CMT), reductase test and alcohol test to detect subclinical mastitis in dairy cattle. The number of samples taken was 60 samples of fresh dairy milk from 15 cattles in Medowo Village as much as 50 ml for each sample. The results showed that the test was very effective in identifying subclinical mastitis in dairy cattle. 15% positive results were obtained for subclinical mastitis using CMT, 10% of the milk quality was not good during the reductase test and 18.33% positive with the alcohol test from a total of 60 samples obtained.</p> Eriza Rosalina Rochmah, Dadik Raharjo, Sri Hidanah, Mustofa Helmi Effendi, Adiana Mutamsari Witaningrum, Sunaryo Hadi Warsito Copyright (c) 2023 Jurnal Agro Veteriner http://creativecommons.org/licenses/by-nc-sa/4.0 https://e-journal.unair.ac.id/agrovet/article/view/51443 Fri, 01 Dec 2023 00:00:00 +0700 Commercial Feed Substitution with Milkfish Waste Flour (Chanos chanos) Against Quail (Coturnix coturnix japonica) Egg White Index, Egg Yolk Index and Haugh Unit https://e-journal.unair.ac.id/agrovet/article/view/51497 <p>Quail farming is quite developed, from year to year the population increases. The search for alternative feed as a substitute for feed sources is an effort by breeders to minimize feed costs. One alternative to replace feed ingredients can be fishery industry waste. Fishery waste that can be used as feed is milkfish waste (<em>Chanos chanos</em>). The purpose of this research was to determined the substitution of milkfish waste flour (<em>Chanos chanos</em>) at commercial feed to egg white index, egg yolk index and haugh unit. There are 20 quails (<em>Coturnix coturnix japonica</em>) at one day of age of four treatments and five replications. Each treatment consisted by five females. The treatment consisted of P0 with commercial feed 100%, P1 with commercial feed 98% + milkfish waste flour 2%, P2 with commercial feed 96% + milkfish waste flour 4% and P3 with commercial feed 94% + milkfish waste flour 6%. Based on results of the Analysis of Variance (ANOVA) there was not significantly different (p&gt;0,05) on egg white index, egg yolk index and haugh unit. It can be concluded the substitution of commercial feed with milkfish waste flour (<em>Chanos chanos</em>) can maintain egg white index egg yolk index and haugh unit.</p> Annisa Nur Aulia Purwantoro, Sri Hidanah, Dhandy Koesoemo Wardhana, Mohammad Anam Al Arif, Sunaryo Hadi Warsito, Widya Paramita Lokapirnasari Copyright (c) 2023 Jurnal Agro Veteriner http://creativecommons.org/licenses/by-nc-sa/4.0 https://e-journal.unair.ac.id/agrovet/article/view/51497 Fri, 01 Dec 2023 00:00:00 +0700 Addition of Bacillus subtilis BN Strain Probiotic on Chicken Eggs Quality https://e-journal.unair.ac.id/agrovet/article/view/51498 <p>The addition of probiotics is one effort to increase the chicken's appetite. There are many probiotics that can be mixed into feed to help improve the digestive and reproductive systems, including <em>Bacillus subtilis</em>, which has the function of increasing egg quality, including increasing shell thickness, increasing egg volume, increasing egg yolk and white index. This reseacrh aims to find out the effect of probiotic administration of <em>Bacillus subtilis BN Strain</em> on shell thickness, white index and chicken yolk index. This research used 38-week-old layer laying hens as many as 24 heads, randomized into four treatments with eight replays.&nbsp;Based on the analysis of statistical data, the Analysis Of Variance (ANOVA) test showed no noticeable difference (p&gt;0.05) to the thickness of the shell, white index or egg yolk index. The results showed that the addition of probiotic <em>Bacillus subtilis BN Strain</em> as many as 0.005 grams/kg of feed, 0.01 grams/kg of feed and 0.02 kg/kg of feed had no noticeable effect on the increase in egg shell thickness, egg white index and egg yolk index.</p> Muhammad Agil Gumilang, Widya Paramita Lokapirnasari, Mochamad Lazuardi, Mohammad Anam Al Arif, Sunaryo Hadi Warsito, Sri Chusniati Copyright (c) 2023 Jurnal Agro Veteriner http://creativecommons.org/licenses/by-nc-sa/4.0 https://e-journal.unair.ac.id/agrovet/article/view/51498 Fri, 01 Dec 2023 00:00:00 +0700 Black Soldier Fly (Hermetia illucens) Maggot Flour as Concentrate Substitution on Broiler Chickens Feed Consumption, Body Weight Gain and Feed Conversion Ratio https://e-journal.unair.ac.id/agrovet/article/view/51502 <p>This study aims to determine the effect of concentrate substitution with maggot Black Soldier Fly (<em>Hermetia illucens</em>) flour on feed consumption, body weight gain and feed conversion ratio of broiler chickens. This study was an experimental study with a completely randomized design (CRD) with 5 treatment and 4 replications. The material uses broiler chickens age four weeks as many as 20 tails, the feed used is concentrate from the PT. Charoen Pokphand Indonesia, maggot BSF flour, corn and bran. The feed treatment with the addition of maggot BSF flour consisted of P0 (feed without maggot BSF flour), P1 (2% addition of maggot BSF flour), P2 (4% addition of maggot BSF flour), P3 (6% addition of maggot BSF flour), and P4 (8% addition of maggot BSF flour). From the study results obtained the mean and standard deviation of feed consumption, body weight gain and feed conversion of broiler chickens. Analisys of Variance (ANOVA) showed that the subtitution of concentrate with maggot flour from black soldier flies had no significated effect (p&gt;0.05) on the feed consumption, body weight gain and feed conversion ratio of broiler chickens.</p> Magdalena Eki Pertiwi, Sri Hidanah, Nove Hidajati, Mirni Lamid, Widya Paramita Lokapirnasari, Sunaryo Hadi Warsito Copyright (c) 2023 Jurnal Agro Veteriner http://creativecommons.org/licenses/by-nc-sa/4.0 https://e-journal.unair.ac.id/agrovet/article/view/51502 Fri, 01 Dec 2023 00:00:00 +0700 Moringa oleifera Flour Fermentation as Feed Additive on Egg Quality in Mojosari Ducks with Different Storage Period https://e-journal.unair.ac.id/agrovet/article/view/51683 <p>Eggs are widely consumed by Indonesian people. High market demand will cause breeders to increase egg productivity and quality. <em>Moringa oleifera</em> leaves addition to the feed could increase egg production. Moringa leaf flour has high crude fiber, so it needs to be fermented. Fermentation aims to reduce crude fiber and increase crude protein. This study aims to determine the effect of using fermented Moringa leaf flour on the egg yolk index of the Haugh Unit and the color of the Mojosari's duck egg yolk with different shelf life. 60 ducks divided into four treatment groups, namely P0 without fermented Moringa leaf flour addition, P1 with 0.5% Moringa leaf flour fermentation, P2 with 1% Moringa leaf flour fermentation, and P3 with 1.5%. Moringa leaf flour fermentation. The results showed that the addition of 1.5% fermented Moringa leaf flour (P3) gave the highest average value for the egg yolk index, Haugh Unit, and egg yolk color with different storage period. Providing fermented <em>Moringa oleifera</em> leaf flour at 1.5% as a feed additive had the highest influence on increasing the egg yolk index, haugh unit value, and egg yolk color of mojosari ducks with different storage period.</p> Rahmaniar Larasati, Sri Hidanah, Muchammad Yunus, Widya Paramita Lokapirnasari, Emy Koestanti Sabdoningrum, Mohammad Anam Al Arif Copyright (c) 2023 Jurnal Agro Veteriner http://creativecommons.org/licenses/by-nc-sa/4.0 https://e-journal.unair.ac.id/agrovet/article/view/51683 Fri, 01 Dec 2023 00:00:00 +0700
