Background. The research objective was to assess The Addition of an Acidifier in Feed Containing Probiotics of Egg Index and Egg Mass of Sentul Chickens. Materials and Methods. The material used was 60 female sentul chickens aged 5 months, with 4 treatments, 5 repetitions, and each experimental unit consists of 3 chicken. Treatment: R0 = basal feed; R1 = basal feed + probiotic with lactic acid acidifier 0.5%; R2 = basal feed + probiotic with lactic acid acidifier 1.0%; R3 = basal feed + probiotic with lactic acid acidifier 1.5%. Design with CRD (completely randomized design) and data analysis using ANOVA. Results. The results of the analysis of variance showed that the treatment had no significant effect (P> 0.05) on egg index and egg mass of Sentul chicken. Conclusion. It was concluded that the addition of lactic acid as an acidifier in feed containing probiotics up to a level 1,5% was not able to improve the quality of egg index and egg mass of Sentul chickens.

Background. The large number of species spread across Indonesia cannot be separated from the domestication process which helps improve and maintain livestock species by humans to maintain food needs for animals such as the domestication of the Sentul chicken. Poor feed efficiency for Sentul chickens has caused Sentul chickens to depend on antibiotics and has been banned since 2018. Lactic acid is believed to be an alternative to antibiotics and has been studied for a long time. The liver is an organ that can represent the state of the chicken if lactic acid is identified as a hazardous substance through the content of SGPT and SGOT. This study aims to evaluate the use of lactic acid as an acidifier in sentul chickens found in the liver seen from the content of SGOT and SGPT. Materials and Methods. There were 60 Sentul chickens used in this study which measured the content of SGOT and SGPT. Results. The addition of lactic acid significantly (p>0.05) did not have a negative effect on the liver in both SGOT and SGPT at administration levels up to 2% (v/g). SGOT and SGPT in the negative control were 232.9 and 39.68 mmol/L while the addition of lactic acid was still in a range that was not too far away, namely for SGOT in the range of 234.6-281.2 mmol/L and SGPT 35.15-56.96 mmol/L. Conclusion. The use of lactic acid in Sentul chicken feed does not cause liver damage which can be seen in SGOT and SGPT levels.

Salah satu bahan pakan dengan sumber protein tinggi adalah bungkil kedelai. Namun, saat ini bahan pakan tersebut masih di impor dari luar negeri, yang menyebabkan bungkil kedelai memiliki harga yang relatif tinggi dan jumlahnya terbatas. Pengurangan ketergantungan akan bahan pakan bungkil kedelai dilakukan dengan mengeksplorasi bahan pakan lokal dengan keteenrsediaan jumlah yang memadai dan memiliki kandungan nutrient yang tinggi. Tujuan dari penelitian ini adalah untuk mengetahui titik isoelektrik, kandungan asam amino total dan kandungan zat antinutrisi tanin yang tepat pada pembuatan konsentrat protein daun Indigofera zollingeriana hasil dari ekstrasi dan isolasi protein. Tahapan ekstrasi dilakukan 2 tahap, NaOH 0,05 N pH 8 pada ekstrasi tahap pertama dan buffer asetat pH 4 pada tahap kedua. Penentuan isoelektrik, menurut menggunakan metode Yatno (2009) modifikasi high-performance liquid chromatography (HPLC) untuk kandungan asam amino total. Analisis protein kasar, menurut AOAC (2005) digunakan metode kjedhal, dan metode butanol-HCl digunakan pada uji kandungan zat antinutrisi tanin. Penelitian ini menghasilkan titik isoelektrik konsentrat protein pada daun Indigofera zollingeriana tercapai pada NaOH 0,05 N pH 8 pada ekstraksi pertama dan buffer fosfat pH 8 pada ekstraksi kedua menghasilkan endapan 0,108 g/ gramBKdaun dengan kandungan protein kasar sebesar 65,98% (lebih tinggi dari bungkil kedelai) serta kandungan asam amino yang lebih lengkap dari bungkil kedelai dan tidak memiliki kandungan tanin.

The availability of forage in Indonesia is highly fluctuating, thereby hindering the sustainability of ruminant livestock farming. This study was conducted to optimize the potential of waste by improving the quality of nutrients contained therein through appropriate technology. An exploratory study was conducted by applying ammoniation technology using 3% urea and fermentation using 8% Trichoderma viride on several types of agro-industrial waste, including banana stems (ares), corn husks, peanut shells, durian skins, and pineapple skins. The parameters measured included dry matter digestibility, organic matter digestibility, volatile fatty acid concentration, and ammonia nitrogen (N-NH₃) production. The data were analyzed using descriptive methods. The results showed that ammoniation and fermentation treatments altered the nutrient characteristics of the feed materials and increased in vitro nutrient digestibility, particularly improving nutrient availability. Overall, these findings indicate that processing local feed sources through ammoniation and fermentation can improve nutrient availability and represent a promising strategy for developing efficient alternative feed sources for ruminants.

The objective of this study was to evaluate the effect of Bamboo leaf extract supplementation on the digestibility of dry matter, organic matter, crude protein, crude fat, and inter-parameter correlation in broiler chickens induced by heat stress. The research material used 200 unsexed broiler chickens with an average weight of 42 g. The research method used was a completely randomized design with 4 treatments and 5 replicates, namely: P0 = commercial feed, P1 = basal feed, P2 = basal feed with 1.5 g kg-1 bamboo leaf extract, and P3 = basal feed with 3 g kg-1 bamboo leaf extract. The research variables included the consumption and digestibility of dry matter (DM), organic matter (OM), crude protein (CP), and crude fat (CF) of broiler chickens. The results showed that the addition of bamboo leaf extract had no significant effect on the digestibility of DM, OM, CP, and CR. However, the treatment with the highest extract level (P3 = 3 g kg-1) showed a better trend in DM (82.05%) and OM (46.48%) digestibility compared to other treatments. These results indicate that bamboo leaf extract has potential as a natural feed additive to support broiler chicken digestion, although the increase observed was not statistically significant. These findings are expected to serve as a basis for the development of natural ingredients in feed as an alternative to conventional additives.
