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> 2023-12-01T00:00:00+07:00 Copyright (c) 2023 Jurnal Agro Veteriner https://e-journal.unair.ac.id/agrovet/article/view/51392 Probiotics Addition Potential to Increase Body Weight, Feed Consumption and Feed Conversion on Pre-Layer Laying Hens 2023-11-09T07:41:58+07:00 Sukmawati Lailatul Jannah mirnylamid@fkh.unair.ac.id Mirni Lamid mirnylamid@fkh.unair.ac.id Mohammad Sukmanadi mirnylamid@fkh.unair.ac.id Mohammad Anam Al Arif mirnylamid@fkh.unair.ac.id Sri Hidanah mirnylamid@fkh.unair.ac.id Sri Chusniati mirnylamid@fkh.unair.ac.id <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> 2023-12-01T00:00:00+07:00 Copyright (c) 2023 Jurnal Agro Veteriner https://e-journal.unair.ac.id/agrovet/article/view/51393 White Kupang Flour (Corbula faba hinds), Fish Meal and Coconut Oil Usage on the Broilers Carcass Percentage and Abdominal Fat 2023-11-09T07:52:52+07:00 Virgy Dzakina Fahrezy mirnylamid@fkh.unair.ac.id Mirni Lamid mirnylamid@fkh.unair.ac.id Setiawan Koesdarto mirnylamid@fkh.unair.ac.id Emy Koestanti Sabdoningrum mirnylamid@fkh.unair.ac.id Widya Paramita Lokapirnasari mirnylamid@fkh.unair.ac.id Sunaryo Hadi Warsito mirnylamid@fkh.unair.ac.id <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.

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> 2023-12-01T00:00:00+07:00 Copyright (c) 2023 Jurnal Agro Veteriner https://e-journal.unair.ac.id/agrovet/article/view/51498 Addition of Bacillus subtilis BN Strain Probiotic on Chicken Eggs Quality 2023-11-13T12:31:16+07:00 Muhammad Agil Gumilang widya-p-l@fkh.unair.ac.id Widya Paramita Lokapirnasari widya-p-lo@fkh.unair.ac.id Mochamad Lazuardi widya-p-l@fkh.unair.ac.id Mohammad Anam Al Arif widya-p-l@fkh.unair.ac.id Sunaryo Hadi Warsito widya-p-l@fkh.unair.ac.id Sri Chusniati widya-p-l@fkh.unair.ac.id <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.

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> 2023-12-01T00:00:00+07:00 Copyright (c) 2023 Jurnal Agro Veteriner
