Pemberian Tepung Bawang Dayak (Eleutherine palmifolia) dalam Pakan terhadap Profil Hematologi Darah Puyuh

2024-09-01T11:34:18+07:00

The study evaluated the effects of feeding Bawang Dayak (Eleutherine palmifolia) meal in the diet on the hematology profile in quails. A total of 160-layer quails (Coturnix-coturnix japonica strain) aged 8 weeks to 14 weeks were assigned on a completely randomized design (CRD) with 4 treatments, 4 replications with 10 quails per replication. The treatments consisted of R1 = diet control, R2 = diet contained 0.1% Bawang Dayak meal, R3 = diet contained 0.2% Bawang Dayak meal, and R4 = diet contained 0.3% Bawang Dayak meal. The variables observed were the hematology profile quail, including erythrocytes, hemoglobin, leukocytes, hematocrit, lymphocytes, heterophils, eosinophils, monocytes, basophils, and the ratio of heterophils to lymphocytes (H/L). Data were analyzed using analysis of variance (ANOVA), and any significant differences were tested using a post hoc Tukey test. The results showed that the usage of Bawang Dayak meal as a phytobiotic in the diet up to 0.3% did not affect quail blood hematology such as erythrocytes, hemoglobin, leukocytes, hematocrit, leukocyte differentiation and the ratio of H/L. The inclusion of 0.2% Bawang Dayak meal resulted in the H/L ratio being within normal conditions, reflecting its function to maintain stress levels of layer quails. In conclusion, utilization of Bawang Dayak meal in a diet of up to 0.3% does not affect the hematological profile of quail.

Jack Bean (Canavalia ensiformis) Meal Inclusion and Lactic Acid Bacteria Supplementation on the Performance of IPB D1 Chickens

2024-09-01T11:34:19+07:00

This study investigates the effects of including jack bean (Canavalia ensiformis) meal in the ration and lactic acid bacteria (LAB) supplementation on the performance and carcass yield of IPB D1 chickens. Jack bean meal (JBM) contains a high-energy, protein-rich feed ingredient that can substitute soybean meal, though it contains antinutrients such as hydrocyanic acid. Pre-treating jack beans through soaking and peeling reduces these antinutrients, allowing JBM to replace up to 20% of the diet. The inclusion of exogenous enzymes like protease can further enhance nutrient absorption and broiler health. The study involved 240 IPB D1 chickens, divided into four groups: control feed without LAB (J0L0), control feed with LAB (J0L1), treatment feed without LAB (J1L0), and treatment feed with LAB (J1L1). Feed intake, body weight gain (BWG), and feed conversion ratio (FCR) were measured weekly from weeks 3 to 9, and carcass yields were evaluated at the end of the study. Results showed significant variations (p<0.05) in weekly feed intake, BWG, and FCR across the treatments. Chickens fed JBM had lower (p<0.05) feed intake and BWG but these improved with LAB supplementation. FCR values improved significantly (p<0.05) with LAB supplementation in both control and treatment feeds. Carcass yield analysis indicated that LAB supplementation led to higher (p<0.05) final body weight and carcass yield, while JBM inclusion resulted in lower values (p<0.05). The study concludes that while JBM can negatively affect chicken performance due to antinutrients, LAB supplementation can mitigate these effects, enhancing both performance and carcass yield. In addition, probiotics are beneficial in poultry diets, counteracting antinutritional factors in feed ingredients like Jack bean meal.

Daya Cerna dan Karakteristik Fermentasi Rumen dengan Penambahan Asam Amino Terenkapsulasi secara In Vitro

2024-09-01T11:34:20+07:00

Amino acid protection is one of the efforts to improve livestock feed quality. Lysine is one of the limiting amino acids, which is easily degraded in the rumen, and thus requires a protection. This study aimed to determine the effect of protected lysine on cattle's digestive system and ruminal ecology in vitro. This study used encapsulation using xanthan gum and tannin (2% w/v) to protect lysine. The treatments consisted of P0 = unprotected amino acids; P1 = amino acids + 2 g xanthan gum; P2 = amino acids + 2 g tannin; P3 = amino acids + 2 g xanthan gum + 2 g tannin. Parameters observed included nutrient content, chemical activity, degradability of organic matter (OM) and crude protein (CP), and rumen fermentability (pH, N-NH₃, VFA, gas kinetics, and CH₄). A combination of xanthan gum and tannin coatings (P3) resulted in a higher effect (p<0.05) on rumen fermentation compared to others. The Undegraded DM and CP values in the rumen were 48% and 32%, respectively, and in the pepsin-HCl were 15% and 89%. All treatments did not change the rumen fermentability. In conclusion, protected amino acids has a effect on the cattle digestion system without disturbing the rumen ecology. Combining xanthan gum and tannin coatings provides the best results than using a single type of coating.

The objective of this study is to evaluate the effectiveness of creep feed containing Indigofera and Black Soldier Fly (BSF) maggot meal and Indigofera on the performance and meat quality of Dorper lambs. The study involved 21 male lambs aged 3 months with an average weight of 20.03 ± 1.71 kg. A Completely Randomized Design (CRD) with 3 treatments and 7 replications was used, namely PM = Martabe feed, P1 = Indigofera creep feed, and P2 = BSF maggot creep feed. Parameters observed included performance, carcass characteristics, physical meat quality, nutrient composition, and fatty acid profile of Dorper lamb meat. Data were analyzed using Analysis of Variance (ANOVA), and significant differences were further analyzed using Duncan's test. The results showed that P2 significantly increased (p<0.05) consumption, daily weight gain, and carcass percentage compared to the other treatments. Although P1 did not show a significant difference in performance compared to the other treatments, it significantly affected (p<0.05) the protein content and improved the fatty acid profile of the meat. In conclusion, PM showed lower FCR and higher carcass percentage. P1 increased crude protein content of the meat, although it did not significantly affect physical meat quality. P2 improved ADG and carcass percentage of Dorper lambs compared to P1.

Evaluasi Efektivitas Pemberian Kalsium dengan Metode Split-Feeding terhadap Produtivitas Puyuh Petelur

2024-09-01T11:34:21+07:00

High-productivity laying poultry during the production period may experience bone problems, as structural medullary bone is progressively absorbed to supply calcium for eggshell formation. This study aims to evaluate the usage of different particle sizes of limestone (fine (0,025mm), and coarse (1mm)), and split feeding system (morning (8 am) and afternoon (15 pm)) on laying quail productivity. This research used 160 quail aged 18 weeks, which is reared up to 23 weeks. A complete randomized design (CRD) with 4 treatments and 4 replicates was used in this study. Each replicate consisted of 10 quails. The cages used were multilevel colonies equipped with feed and drink containers. The diet treatments were: P0= diet contained fine (FL) and coarse (CL) limestone at a (25:25): (25:25) ratio fed in the morning and afternoon, P1= diet contained 75FL-(Morning): 25CL-(Afternoon), P2= diet contained 50FL-(Morning):50CL-(Afternoon) and P3= diet contained 25FL-(Morning):75CL-(Afternoon). Data were analyzed using ANOVA and further analyzed using the Duncan test. The results showed that the ration treatment with limestone divided into fine and coarse forms with split feeding in the morning and evening significantly increased (p<0.05) tibia bone Ca and P content but decreased (p<0.05) feed conversion. However, it increased (p<0.05) quail egg index value. Feeding calcium at a ratio of 25% (morning) and 75% (afternoon) resulted in the highest ration utilization efficiency, Ca and P deposits in the tibia bone, and increased egg index values.
