2025-05-17T16:52:05+07:00

This research was conducted to determine the impact of substituting commercial feed with agroindustrial by-product feed on the growth performance of pigs in the grower phase and the benefits obtained by farmers. A total of 20 pigs aged 18 weeks were tested in a randomized block design with four treatments and five replications. The feed treatments were P0= commercial feed (CP 552), P1= 50% CP552 and 50% agroindustry feed, P2= 100% agroindustry feed, and P3= P2 feed with the addition of phytase and mannase enzymes. The results showed that feed consumption, body weight gain, and feed conversion were not significantly different among the treatments. The digestibility of the P0 was significantly higher than that of P1, P2, and P3 (p<0.05). The digestibility of the P3 was not significantly different from that of the P1; however, it was significantly higher than P2 (p<0.05). The IOFC of P2 was higher than P0 and P1, while P3 resulted in the highest IOFC among treatments. It can be concluded that utilizing feed containing agro-industrial by-products could substitute 100% of commercial feed in growing pigs and provides 60% higher income than commercial feed. Moreover, additional phytase and mannase enzymes on agroindustrial by-products feed might provide 89% higher income than commercial feed.

Local Rooster is potentially to be developed, because it has adaptive characteristics and is easy to raise. Giving probiotics to local rooster is considered important to increase endurance and decrease mortality in livestock. The purpose of the study was to determine the effect of single-strain or multistrain probiotic supplementation, namely Lactobacillus sp. and Bacillus subtilis. This study used a Completely Randomized Design (CRD) with four treatments and five replications, namely P0: Feed + 0% Probiotic; P1: Feed + 1% Single Probiotic Bacillus subtilis; P2: Feed + 1% Single Probiotic Lactobacillus sp.; P3: Feed + 1% Multi Probiotic Bacillus subtilis and Lactobacillus sp. The blood profiles observed were hemoglobin, erythrocytes, hematocrit, erythrocyte indices consisting of Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin (MCH), and Mean Corpuscular Hemoglobin Concentration (MCHC), leukocytes, neutrophils, lymphocytes, monocytes, and platelets. Data was analyzed using Analysis of Variance (ANOVA) and continued using Duncan Multiple Range Test (DMRT). The study results showed a significant effect between treatments (p<0.05) in the MHC content in the blood of local roosters. However, all treatments had no effect on other blood parameters. It can be concluded that supplementation of a single probiotic of B. Subtilis and Lactobacillus sp. could reduce the MCH value of the Local Rooster then improve the body's immune system. However, it did not affect the number of hemoglobin, erythrocytes, hematocrit, MCH, MCHC, leukocytes, lymphocytes, monocytes, and thrombocytes.

2025-05-27T03:53:32+07:00

This study aims to evaluate the quality of Arbuscular Mycorrhizal Fungi (AMF) inoculum produced using various nutrient fortification methods for Desmanthus virgatus plants in helping to cope with salinity stress. This study was conducted at the Agrostology Laboratory of IPB University with a Completely Randomized Design (CRD) Factorial Pattern 5 x 3 with 8 replications. Factor A was types of AMF, namely AMF without administration (JM0), commercial/superior AMF (JMU), AMF fortified with AB Mix 1000 ppm (JM1), AMF fortified with AB Mix 2000 ppm (JM2), and AMF fortified with AB Mix 3000 ppm (JM3). Factor B was levels of soil salinity, namely control soil (JT0), medium saline soil (JT1), and high saline soil (JT2). Each plant was given 20 g of AMF, compost, and NPK fertilizers. Both plants without AMF and with AMF were given different doses of fertilizer, namely 100% dose and 50% dose. The results showed that inoculation of JMU, JM1, JM2 and JM3 had the same AMF colonization consistency in JT0, JT1 and JT2. AMF inoculation of JMU, JM1, JM2, and JM3 effectively increased (p<0.05) the vertical height of Desmanthus virgatus on high saline soil (JT2). The production of dry weight of JM3 shoots on high saline soil (JT2) was the highest (p<0.05) among other treatments. Leaf chlorophyll of JMU, JM1, JM2, and JM3 in control soil (JT0) was significantly higher than JM0, but it was not significantly different in medium saline soil (JT1) and high saline soil (JT2). AMF inoculation with JMU, JM1, JM2, and JM3 effectively reduced leaf proline content in highly saline soil (JT2), while salinity significantly (p<0.05) increased the leaf proline levels of Desmanthus virgatus. The conclusion was that AMF could increase the productivity of Desmanthus virgatus legumes on high-salinity soil. Desmanthus virgatus has an acceptable tolerance level on medium and high saline soils. Arbuscular Mycorrhizal Fungi JM3 (result of AB Mix 3000 ppm fortification) has a better production ability than JM1, JM2, and JMU on high saline soil.

The purpose of this study was to evaluate the performance of prolific lambs fed milk replacer derived from mackerel peptone with prolific lambs fed mother’s milk. This study used six twin born lambs aged 1 week with an average birth weight of ± 2.05 kg and male. The treatments applied in this study were mother’s milk (P0) and milk replacer containing 100% mackerel peptone (P1). The observed variables included ash content, crude protein content, crude fat content, calcium content, phosphorus content, total nitrogen, total volatile base (TVB) content, milk amino acid profile, milk consumption, body weight gain, feed conversion rate, and mortality. The results showed that milk replacer containing 100% mackerel peptone had high crude protein content and complete amino acid composition. Prolific lambs fed with milk replacers showed no significant difference in body weight gain compared to those suckling from their mothers. Additionally, lambs receiving the milk replacer did not exhibit any signs of digestive disorders, loss of appetite, abnormal behavior, or mortality during the maintenance period. Utilization of mackerel peptone as an alternative protein source can be used up to 100% in milk replacer. It can be concluded that feeding milk replacers formulated with mackerel peptone resulted in a 1.30% increase in lamb body weight, with no significant difference observed in performance compared to lambs suckling form their mothers.

The content of active compounds in natural materials is generally low and highly variable, thus requiring efficient and selective extraction methods. This study aims to evaluate a stepwise extraction process applied to the seeds, oil, and by-products of Nigella sativa (black cumin) to obtain thymoquinone (TQ) and other phytochemicals. The study consisted of four main stages: (1) extraction of HS oil using the cold press method, (2) stepwise extraction using 70% ethanol as solvent, (3) analysis of TQ content and phytochemical compounds in the extracts, and (4) evaluation of the antibacterial activity of habbatussauda oil extracts against pathogenic and non-pathogenic bacteria. Results showed that the cold press method yielded 34.46% oil. Stepwise extraction using 70% ethanol resulted in significant differences (p<0.05) in both yield and TQ content among the seed, oil, and by-product extracts. Among all samples, the ethanol extract from habbatussauda oil exhibited the highest yield and TQ concentration. Furthermore, at a concentration of 100 μg mL⁻¹, this extract inhibited the growth of pathogenic bacteria such as Salmonella typhimurium and Escherichia coli, without affecting non-pathogenic strains like Lactobacillus spp. and Bifidobacteria spp. In conclusion, stepwise extraction using 70% ethanol proved effective in enhancing TQ recovery and demonstrated potential as a phytobiotic agent with selective antibacterial activity against pathogenic bacteria.
