The method and duration of storage are crucial factors determining quality of fresh milk, as assessed by total bacterial, fat content, and protein content of fresh milk. This research aims to determine the comparison of the total bacterial count, fat content, and protein content of fresh milk stored at a low temperature and at room temperature. The research subjects used were fresh milk obtained from a single cow in a single milking process, stored at a low temperature of 4 – 6 ℃ and at room temperature, and then tested and compared for the total bacterial count, fat content, and protein content after storage for the 2nd, 4th, and 6th hours. The data obtained was statistically analyzed using the student’s t-test at a confidence level of α = 95%. The result showed that there a significant difference (p<0,05) in total bacterial and fat content. Within 6 hours, at a low temperature, total bacterial increased from the initial 3,07 × 105 cfu/ml to 5,95 × 105 cfu/ml, while at room temperature, it rose to 21.02 × 105 cfu/ml. The initial fat content was 4,14%, and after 6 hours of storage, at a low temperature, fat content decreased to 3,35%, whereas at room temperature, it dropped below the SNI standard of 3 to 2,91%. As for the protein content of the milk, both at low and room temperatures, the protein did not decrease and did not show a significant difference (p<0,05). It can be concluded that up to two hours of storage, the quality of milk is not affected by temperature. However, after being stored for more than two hours, the storage temperature does impact the total bacterial count and the fat content of the milk.

This research aims to determined the effect of feed adequacy on the production and quality of dairy goat milk in Turi District. This research was carried out in the field and laboratory from 01 to 24 October 2023. A total of 98 dairy goat breeders were selected as respondents with the criteria of having at least 1 year of farming experience and having at least 2 animals. From each goat they raise, milk samples are taken to test the quality in the laboratory. The data obtained were analyzed descriptively and by multiple linear regression analysis. The results showed that the average age of farmers is 44 years, with an education level of 86% high school graduates, the number of family dependents of 4-5 people is 67%, the majority work as farmers 52% (69% ≤10 years and 31% ≥11 years). Livestock ownership status is 100% privately owned with an average ownership of 2-5 heads. The average body weight of dairy goats was 40.13 ± 6.91 kg, with milk production of 2.21 ± 0.51 liters/day. Furthermore, the milk quality variable shows that the average specific gravity and non-fat solids are 1.055 ± 0.08 and 8.42 ± 0.43. Feed adequacy (Dry Matter) is 1.43 and Crude Protein adequacy is 7.44. Milk production was significantly (p<0.05) 52.6% influenced by the level of feed adequacy with the regression equation Y = -1.513 + 0.033XI + 0.495X2. Meanwhile, milk density was 48.5% influenced by the level of feed adequacy (p>0.05) with the regression equation Y = 1.043 + 0.073XI - 0.013X2. Likewise, the lean solitaire variable which was not significant (p>0.05) was influenced by the level of feed adequacy (0.75%) with the regression equation Y = 6.874 + 0.155XI + 0.183X2. It was concluded that the adequacy of feed for dairy goats in Turi District for production was sufficient and for milk quality it was in accordance with the 2011 SNI.

This study aimed to evaluate the effect of adding fermentation additives on the organoleptic quality and palatability of silo-fermented silage. Four treatments were tested in a completely randomized design: P1 (no additive), P2 (molasses), P3 (molasses + probiotics), and P4 (complete feed: molasses + probiotics + concentrate), each with six replications, and a palatability test involving five dairy cows. The silage was assessed based on organoleptic parameters and actual feed intake. The observed variables were organoleptic properties (aroma, smell, color, and texture) and palatability indicators (feeding duration and feed intake). The data obtained were analyzed using Analysis of Variance (ANOVA) followed by the Duncan Multiple Range Test (DMRT). The results indicated that the addition of fermentation additives did not have a significant effect (P>0.05) on aroma, texture, color, or palatability levels. These findings suggest that the forage quality and the fermentation conditions within the silo were optimal, resulting in no noticeable differences among treatments. The implications of this study highlight the need for further investigation into the dosage, composition, and forage characteristics of fermentation additives to achieve more distinct and applicable improvements in silage quality within dairy production systems

Pakan aditif khususnya ternak ruminansia dapat dibuat dari berbahan dasar kimia dan alami. Penggunaan aditif berbahan dasar kimiawi lebih banyak digunakan karena efektivitas lebih cepat terlihat dan mendapatkan dosis yang tepat. Namun, penggunaan tersebut menimbulkan residu terhadap produk hasil dari ternak. Aditif alami sebagai pakan ternak terutama ruminansia semakin diperhatikan sebagai pendekatan yang berkelanjutan dalam meningkatkan performa, kualitas produk sampai dengan kesehatanya. Aditif alami bersumber dari berbagai tanaman yang memiliki senyawa bioaktif diantaranya flavonoid, fenolik, dan glikosida. Daun stevia (Stevia rebaudiana) adalah tanaman yang sudah banyak dikembangkan dalam industri pangan sebagai pemanis alami namun belum banyak digunakan dalam bidang peternakan. Potensi senyawa yang dimiliki tanaman tersebut berpotensi dapat bermanfaat untuk pakan ternak. Artikel review bertujuan untuk mengevaluasi peran daun Stevia rebaudiana sebagai pakan aditif alami pada ternak ruminansia yang berpengaruh terhadap konsumsi pakan, fermentasi rumen, kecernaan nutrien, dan performa produksi. Hasil penelitian menunjukkan bahwa penambahan daun stevia dalam ransum dapat meningkatkan palatabilitas sehingga mendorong konsumsi pakan. Di sisi lain, kandungan bioaktif yang dimiliki bersifat antimikroba dan antioksidan yang dapat membantu menjaga keseimbangan mikroba rumen serta mengurangi stres oksidatif sehingga meningkatkan efisiensi fermentasi, termasuk produksi asam lemak volatil dan pemanfaatan nutrien. Penelitian lain menunjukkan adanya peningkatan produksi dan kualitas susu, meskipun hasilnya masih terbatas dan belum konsisten. Namun, pemanfaatan daun stevia sebagai pakan aditif masih menghadapi beberapa kendala, seperti keterbatasan level penggunaan optimal, variasi kandungan bahan aktif, serta aspek ekonomi. Oleh karena itu, diperlukan penelitian lebih lanjut pada daun Stevia rebaudiana yang memiliki potensi sebagai aditif pakan alami untuk mendukung sistem produksi ternak ruminansia yang berkelanjutan.

Performa sapi perah sangat bergantung terhadap pakan yang diberikan setiap harinya. Hijauan dan konsentrat adalah pakan yang umumnya diberikan kepada ternak perah dengan proporsi imbangan 60:40. Imbangan pemberian lainnya dilakukan dengan 50:50. Pemberian yang berbeda tersebut terhadap produktivitas ternak perah seperti sapi, kerbau dan kambing perah belum menghasilkan secara optimal terhadap kuantitas dan kualitas susu. Tanaman fitofarmaka adalah tumbuhan obat-obatan yang banyak ditemukan di wilayah Indonesia dengan memiliki banyak kandungan senyawa antioksidan atau bioaktif antara lain saponin, tanin, flavonoid, dan minyak atsiri yang cocok digunakan sebagai bahan aditif pakan alami. Berbagai eksperimen dengan pemberian tanaman fitofarmaka seperti stevia rebaudiana, kunyit, jahe, daun pepaya, dan bawang putih terhadap campuran ransum ternak perah mampu meningkatkan kinerja sistem rumen sehingga berdampak terhadap perubahan produksi dan kualitas susu. Tidak hanya aspek untuk memperbaiki sistem rumen tetapi meningkatkan serta menjaga kesehatannya. Artikel ini akan mengkaji berbagai jenis tanaman fitofarmaka, mekanisme kerja bioaktif, pemberian pakan terhadap berbagai ternak perah, serta potensi dan tantangan di masa yang akan datang.
