Abstract

This study evaluated the effect of a feed additive combination, Morinda citrifolia leaf extract, citric acid, and Lactobacillus acidophilus (MCL) on broiler chicken performance, carcass traits, and litter quality. MCL contains bioactive compounds such as flavonoids, saponins, citric acid, and probiotic. A total of 200 broiler chickens (8 days old with average body weight 213.88 ± 8.9 g) were randomly assigned to four treatments with five replications of bird each: T0 (control), T1 (1% MCL), T2 (2% MCL), and T3 (3% MCL). Results showed that T2 significantly improved (P<0.05) body weight gain (BWG) and income over feed cost (IOFC). Water consumption and carcass weight were also higher (P<0.05) in T2. Final body weight was significantly higher (P<0.05) in all MCL treatments compared to T0. Feed conversion ratio improved (P<0.05) in T2 and T3. MCL supplementation enhanced carcass traits and litter quality. Cooking loss was lower (P<0.05) in T2, while drip loss and litter pH were reduced (P<0.05) in all MCL treatments. White striping was higher (P<0.05) in T1, and litter temperature was lower (P<0.05) in T2 and T3. These finding suggest that MCL is a promising natural alternative to synthetic growth promotors, improving productivity and probitability in broiler production.

Abstract

Heat stress is a major environmental factor that disrupts reproductive function in poultry, primarily by triggering oxidative stress and inflammation in testicular tissue. This study evaluated the influence of Cucurbita moschata(pumpkin seed) extract in mitigating the adverse effect of heat stress in roosters testes by regulating key markers, heat shock protein 70 (HSP70) and interleukin-6 (IL-6).Twenty-five adult roosters, aged one year, were divided into five groups: a non-stressed control group, a heat-stressed group without treatment, and three heat-stressed groups treated orally with 1600, 3200, or 6400 mg/kg body weight of the extract for 21 consecutive days. Immunohistochemical analysis revealed that heat stress led to marked increases in HSP-70 and IL-6 expression in the testes, reflecting cellular stress and inflammatory responses. Notably, administration of Cucurbita moschataextract attenuated these responses in a dose-dependent manner, with the 3200 and 6400 mg/kg doses showing the most significant reduction in protein expression. These findings highlight the potential role of Cucurbita moschataas a natural therapeutic agent to protect male reproductive function under heat stress conditions through its antioxidant and anti-inflammatory properties.

Abstract

The livestock subsector contributes around sixty percent of the gross domestic product (GDP) of the agricultural sector, and poultry products approximately 80.77% of total national livestock production. Although Indonesia's poultry industry shows great potential, exports of Indonesian broiler products still face various obstacles, for instance geographical distance between countries, exchange rates, Covid-19 pandemic and implementation of Free Trade Agreements (FTA). This study aimed to analyze the determinant factors of the export competitiveness of Indonesian chicken products in the international market with a descriptive quantitative method using Likert-scale questions . This study involved the entire population of 45 individuals, consisting of poultry companies engaged in export activities and relevant government institutions. The Gravity Model approach was employed to examine economic and geographical factors, while the Porter Diamond framework was used to assess the determinants of the industry’s competitive advantage. The results showed that geographical distance (-0.09), exporter GDP (0.27), and importer GDP (0.04) affected to export performance. The most influential factors on Indonesia’s chicken products export competitiveness were firm strategy, structure, and rivalry—particularly product adaptation to target markets (4.61)—and government support through export procedure simplification (4.59). Furthermore, related and supporting industries were found to have a strong correlation with competitiveness. The strengths, weaknesses, opportuni-ties, and threats (SWOT)  analysis resulted diversification strategies in both products and markets, as well as the integration of digital technology in production and distribution become strategic steps to enhance export competitiveness.

Abstract

This study evaluated the impact of dietary clove powder on growth performance, carcass traits, nutrient digestibility, jejunal histomorphometry and ileal microbiota in broiler chickens. A total of 250 Chikun day-old broiler chicks were allocated to 5 dietary groups with 5 replicates of 10 birds each for 6 weeks in a completely randomized design. The groups were fed diets containing clove powder at 0, 0.5, 1.0, 1.5 and 2 g/kg diet. Results showed that dietary clove supplementation improved final body weight and feed conversion ratio (P < 0.001) while reducing total feed intake. Also, it increased weights of live chickens at slaughter, breast meat, shank and drumstick/thigh ratio (P < 0.001). Further, it linearly increased apparent digestibility of DM, CP, and EE (P < 0.01) as it quadratically decreased CF (P < 0.01). Furthermore, it linearly increased jejunal villus length, crypt depth and thickness of muscularis (P < 0.001) whilst it quadratically decreased thickness of the epithelium (P < 0.01). Moreo-ver, it increased ileal Lactobacilli whilst decreasing Salmonella and E. coli (P < 0.05) bacterial species. In conclusion, dietary clove powder improved growth performance, carcass characteristics, nutrient digestibility, gut histomorphometry and Lactobacilli while it decreased Salmonella and E. coli bacteria.

Abstract

The objective was to assess the behavioral indicators of cattle housed in different shade surface availabilities under dry tropical environmental conditions carried out in the summer-autumn period. During 63 days the usual social and agonist variables were recorded in 1,040 bulls housed in 16 pens (4 replicas/treatment, 65 bulls/pen). Ambient temperature (AT) and relative humidity (RH) were record-ed, and the humidity index (THI) was estimated. The shade surfaces tested were 1) conventional shade (S12%), 2) double shade (S24%), 3) shaded 100% without fans (S100), and 4) shaded 100% with fans (S100F). The average maximum value for AT, RH and THI was 38.1°C, 90.7% and 87.6 units. The shade surface influenced the proportion of animals under shade, eating, ruminating, and mounting, and decreased the proportion of animals panting. Pens S24 showed a higher proportion of animals eating and resting (quadratic component, P=0.05). Providing ventilation increased (P=0.01) 2.7 times the pro-portion of animals eating and decreased (P=0.01) 6.5 times the proportion of animals panting. At 0800h a greater proportion of animals eating and riding was observed, while from 1130h onwards the proportion of animals under shade, ruminating and resting increased. At 2:00 p.m., the highest percent-age of animals were panting. It is concluded that  a shaded surface of 12% of the pen area is enough to alleviate behavioral patterns in animals under high environmental heat load. Shade plus ventilation was shown to be a strategy in reducing panting and increasing the proportion of animals in feed bunks.

Abstract

Genetic parameters for egg production traits in the KU-Phuphan black bone chicken, a native Thai breed, were analyzed to estimate heritability, investigate genetic correlations, and provide essential genetic data for developing effective breeding strategies to improve egg production performance. The study focused on traits age at first egg (AFE) and cumulative egg production at 180, 270, 300, and 365 days. Data were collected from 541 hens across three generations raised in an open-house system. Ge-netic parameters, including heritability and genetic correlations, were estimated using the AIREMLF90 software with the average information restricted maximum likelihood method. The results revealed moderate heritability for AFE (0.41) and higher heritability estimates for cumulative egg production traits (0.30–0.50). Genetic correlations among egg production traits were high (0.93–0.99), indicating that these traits were influenced by similar genetic factors. However, the genetic correlations between AFE and egg production traits were low (0.18 to -0.02), suggesting that these traits were influenced by different genetic factors. In conclusion, the potential was highlighted for genetic selection to improve egg production traits in this breed. Therefore, in designing breeding programs, breeders should consid-er the high heritability of egg production traits and the low genetic correlations between AFE and egg production.

Abstract

Capacitation is a prerequisite for successful fertilization with albumin as an inevitable component among the oviductal fluid's constituents. Under in vitroenvironments, albumin's function is replaced by serum-based products, which carry the issue of unsustainability, some allergies, and potential trans-mission of transmissible spongiform encephalopathies (TSEs) to the unborn fetus. To discover an alter-native, sustainable, and innoxious promoter, snakehead fish (Channa striata) albumin was examined for its potential to promote capacitation in bovine sperm. Snakehead fish protein concentrate (SFC) with respective albumin concentrations of 3, 6, and 9 mg/mL was added to the bovine capacitation me-dium. Following the swim-up technique, bovine sperm were incubated in different treatment groups for 90 minutes to stimulate the capacitation process. The results revealed that the application of 3 mg/mL albumin from SFC in Tyrode's-based capacitation medium (T-SFC3) provided sufficient evidence in promoting capacitation, as demonstrated by higher sperm exhibiting hyperactive motility, kinematic parameters, and the percentage of sperm showing B pattern as compared to Tyrode's-based capacitation medium containing 6 mg/mL BSA (T-BSA6) (p>0.05) and other levels of T-SFCs (p<0.05). In con-trast, greater concentrations of SFC application retrieved more viable sperm with intact acrosomes and less in both viable and mortal sperm with reactive acrosomes (p<0.05).

Abstract

This study aimed to evaluate the effects of adding basil (Ocimum basilicum L.) leaf meal waste to feed on stress indicators, immune responses, and performance of growing quails (Coturnix coturnix japonica). Two hundred female quails 3-week-old were allocated in a completely randomized design with four treatments: 0% (P0), 1.5% (P1), 3% (P2), and 4.5% (P3), each with five replicates of 10 birds. The Observed variables included oxygen saturation, heterophil/lymphocyte ratio, hepatic superoxide dismutase (SOD) activity and malondialdehyde (MDA) level, leukocyte profiles, and clearance ability against Salmonella pullorum. Growth performance was measured through feed intake, body weight gain, and feed conversion ratio. Results showed that 3% basil leaf meal waste improved oxygen saturation and SOD activity, reduced H/L ratio and MDA level, and produced the highest bacterial killing ability. The best growth performance and most efficient feed conversion were also observed in P2. It can be concluded that 3% inclusion effectively reduces oxidative stress, enhances immunity, and improves quail performance.
