Abstract

Local genetic resources have an important place in poultry production in Africa. However, knowledge of these genetic resources and their breeding systems is quite often limited. This study was carried out in Seno province/Burkina Faso and aimed to characterize the local chicken production system, the genetic resources used and their management in this area. A survey was conducted including 185 chicken farmers in a rural area. The snowball sampling method was used to co-opt interviewees and, face-to-face interviews were done. The questionnaire includes closed and open-ended questions. Production system characteristics showed that local chickens were bred in free-range production system with few inputs. There were multiple production purposes such as self-consumption (meat and eggs), saving, sale, making donation to strangers. The sale of chickens was ranked as the main purpose with 0.48 as the index, and self-consumption of chicken meat came in second position with 0.34 as the index. According farmers, three phenotypes of chickens ("breed or ecotypes") are encountered in the area. However, these phenotypes are raised together with uncontrolled mating practice, leading to a tendency towards uniformity of phenotypes. Almost all farmers (98.9%) stated they select breeding roosters. This selection is mainly based on growth performance (96.6%). Nevertheless, they ranked "resistance to diseases" as the characteristic they would improve primarily if they had all the possibilities (index 0.43). In general, the production system was extensive with low input, whereas the local chicken genetic resources were under poor management which can lead to genetic erosion.

Abstract

The coastal region of Lebak-Banten is an area with a relatively high population of buffalo. The forage requirement has relied on existing forage with low productivity and quality. The study aimed to investigate the physiological, morphological, and nutritional response of mutant benggala grass in the coastal area and to develop salt-tolerant forage crops with high productivity and nutritive value for livestock. The research was conducted in the Binuangeun coastal area, Muara Village, Wanasalam District, Lebak Regency, located at 6°50’34.4”S and 105°53’23.4”E. This study used a completely randomized block design with a factorial arrangement with 5 replications. The first factor consisted of 4 benggala grass mutants: mutant 12, 18, 36, 56, and a control. The second factor was the location or distance of the planting plots from the coastline (FC), consisting of L1: 50 m FC, L2: 75 m FC, L3: 100 m FC, and L4: 500 m FC, representative of low, moderate, and high salinity levels, and no saline. Observations were made during the dry and rainy seasons. The results showed that mutants 12 and 36 had higher fresh forage production during the rainy season, while mutant 36 had the highest forage production at the L1 location (high salinity conditions) during the dry season. Mutant 12 had higher crude protein values at the L2 location (moderate salinity) than the other mutants and locations (salinity levels) during the dry season. Meanwhile, mutant 18 at the L2 location (moderate salinity) had the highest crude protein value during the rainy season. In addition, mutant 12 had a high proline value at the L1 location (high salinity stress) as a plant adaptation response to salinity stress. The study suggests that mutants 12 and 36 have great potential to be developed into new salt-tolerant forage crop cultivars and can be grown in coastal areas of Lebak-Banten.

Abstract

In recent decades, neuraminidase/sialidase-based antivirals have been produced to suppress respiratory viral infections, including avian influenza, which relies on sialic acid as the entry point for viruses into cells. While neuraminidase has been extensively studied as an antiviral agent, numerous neuraminidases still have not been evaluated for their antiviral activities. Among these is NanB neuraminidase derived from Pasteurella multocida, which has received limited research attention. This study aimed to assess the potential of NanB neuraminidase in inhibiting H9N2 avian influenza virus infection in ovo. The research commenced with the molecular re-identification of the H9N2 A/Layer/Indonesia/WestJava-04/17 virus isolate, followed by determining the EID50 through Rapid HA test results. The toxicity of NanB neuraminidase was assessed by administering various doses to embryonated chicken eggs (ECE). The antiviral activity of NanB neuraminidase on ECE was evaluated through challenge tests, including treatment before, during, and after the challenge. The assessment involved monitoring the time of embryo death, virus titer through HA test, and viral copy number via RT-qPCR. The results indicated that the H9N2 virus titers capable of infecting 50% of ECE amounted to 108.83 EID50/mL. A dose of 0.258 U/mL of NanB neuraminidase was found to be toxic, leading to embryo mortality after 48 hours of incubation at 37 ℃, while a non-toxic dose was determined to be 0.129 U/mL. The post-challenge treatment group exhibited the most significant reduction in virus titer in ECE. Notably, NanB neuraminidase derived from P. multocida demonstrated the ability to inhibit H9N2 avian influenza virus infection in the ovo model, with the optimal dosage of 0.129 U/mL. The observed decrease in virus titers in the hemagglutination assay and viral copy number assays suggests that NanB neuraminidase holds promise as a potential antiviral candidate for therapeutic approach.

Abstract

Escherichia coli (E. coli) is a major cause of mastitis in dairy cattle. Multidrug resistant E. coli poses an important public health threat due to the widespread antimicrobial resistance genes that can transmit to human pathogenic E. coli through consuming contaminated milk. This study aimed to determine the phylogenetic groups and antimicrobial resistance profile of E. coli isolates from bovine clinical mastitis cases. A total of 380 milk samples were collected from dairy farms in Jordan. E. coli was cultured using routine bacterial culture methods and identified initially based on morphological and biochemical characteristics. Suspected bacteria were then confirmed by detecting 16s rRNA gene using traditional PCR methods. The phylogenetic grouping was performed using triplex PCR. The antimicrobial resistance profile was determined using a disc diffusion test followed by the double disc diffusion test to detect ESβLs-producing strains and the syndromic multiplex PCR (mPCR) to detect ESβLs genes. A total of 74 (19.4%) of E. coli strains were isolated from the collected milk samples. The majority of the isolates (52 or 70%) belonged to phylogenetic group A, followed by 13 (17.5%), 7 (9.5%), and 2 (2.7%) isolates that belonged to phylogenetic groups D, B1, and B2, respectively. Sixty-three (85.1%) isolates showed resistance to at least 2 antimicrobial agents, with the highest resistance rates detected against amoxicillin (94.6%), tetracycline (75.7%), and streptomycin (66.2%). Sixty-three (85.1%) isolates showed resistance to at least 2 antimicrobial agents and 23 (31%) isolates showed resistance to at least 2 beta lactam antimicrobial agents. Twenty-two out of 23 (95.6%) of multi-beta lactam resistant isolates were ESβL positive, 22 isolates (100%) carried blaCTX-M gene, and 20 isolates (86.9%) carried the blaTEM gene, while none of the isolates carried the blaSHV gene. The results of this study demonstrate a high prevalence of multidrug resistant, ESβLs-producing E. coli in bovine mastitis, which may represent a serious threat to public health due to the high risk of dissemination of antimicrobial resistance genes through consumption of contaminated milk.

Abstract

The objective of this study was to compare the quality of frozen semen from Toraya buffalo with different lecithins from different commercial diluents. Fresh semen from two 6-9 years old Toraya buffaloes were collected once a week in the morning through an artificial vagina. Fresh semen was examined macroscopically and microscopically. Semen with more than 70% sperm motility was divided into three tubes, each diluted with Andromed (soy lecithin), Steridyl (egg yolk lecithin), and Bovifree (synthetic lecithin) diluents at a concentration of 100 x106 mL-1 motile sperm. The diluted sperm were placed in 0.25 mL straws and allowed to equilibrate for 4 hours. The sperm was frozen above liquid nitrogen favour for 15 minutes and stored in liquid nitrogen containers for further evaluation. The quality of frozen semen was assessed 24 hours after freezing. The parameters tested were motility, viability, abnormalities, plasma membrane integrity, and sperm recovery rate (RR). The results showed no significant differences in the values of motility, viability, abnormalities, plasma membrane integrity, and sperm RR in the three diluents used. Sperm motility values ranged from 45.93% to 47.09% after freezing. Sperm viability ranged from 56.21% to 60.27%. The values of membrane integrity of the three diluents used ranged from 57.73% to 61.36%. The values of sperm abnormalities after freezing and thawing ranged from 2.74% to 3.18%. In conclusion, three commercial diluents containing animal, vegetable, and synthetic lecithin bases can be used as diluents for freezing Toraya buffalo semen with similar results.

Abstract

This study aimed to investigate the genetic impact of single nucleotide polymorphisms (SNPs) of the sterol regulating element binding factor 1 (SREBF1) and scavenger receptor class B member 1 (SCARB1) genes on carcass and meat characteristics, as well as fatty acid composition, in the Bali cattle. The blood and beef samples used for DNA sequencing, physical assessment, and fatty acid analysis were collected from 95 male Bali cattle. The ultrasound images were analyzed using the Image-J NIH software. A total of 4 SNPs were identified in the SREBF1 gene and 5 SNPs in the SCARB1 gene. The results showed that the 4 SNPs in the SREBF1 gene, namely g.12629T>C, g.12731T>C, g.12881A>G, and g.12986C>T, were associated with heptadecanoic acid (C17:0) and cis-11-eicosanoic acid (C20:1). The SNPs g.12731T>C of the SREBF1 gene was associated with fat content, palmitoleic acid (C16:1), stearic acid (C18:0), cis-11-eicosanoic acid (C20:1), and total fatty acids. Furthermore, 4 SNPs in the SCARB1 gene, including g.72219C>T, g.72380C>A, g.72517G>A, and g.72607C>T correlated with longissimus dorsi thickness (LDT). All SNPs in the SCARB1 gene showed significant associations with cis-10 heptadecanoic acid (C17:1) and cis 8,11,14-eicosatrienoic acid (C20:3n6). The SNP g.72400A>G of the SCARB1 gene was related to caprylic acid (C8:0), lauric acid (C12:0), arachidonic acid (C20:4n6), monounsaturated fatty acids (MUFA), and unsaturated fatty acids (UFA). These results suggested that the identified polymorphisms in the SREBF1 and SCARB1 genes could serve as valuable references for investigating similar genes in other cattle breeds, particularly concerning fatty acids.

Abstract

The current meta-analysis aimed to estimate the effect of different selenium (Se) sources on immune organs, plasma immunoglobulins, blood profiles, and broiler performances. Related studies that met standard presence criteria were identified and mined from the Scopus database. The database was developed from 38 articles. Data were analyzed using the OpenMEE, considering the difference between organic selenium as fixed effects and different studies as random effects. This study showed that organic selenium feed supplementation improved the feed conversion ratio and increased the average daily feed intake and gain of broilers. Furthermore, the mortality of broilers fed organic Se was significantly lower than that of those fed inorganic Se. For the immune organ of the broiler, organic selenium feed supplement enhanced the thymus and spleen organs but did not affect the bursa organ. IgA and IgM were significantly higher in the broilers fed organic selenium feed; meanwhile, IgG of broilers fed organic selenium was lower than those fed inorganic selenium. The total protein blood concentration of broilers fed organic selenium was significantly higher than those fed inorganic Se. Meanwhile, there was no statistically significant difference in the effects of selenium source on cholesterol. Triglyceride concentrations of broilers fed organic Se are significantly lower than those fed inorganic Se. The ratio of heterophile to lymphocyte in broilers fed organic Se is significantly lower than in those fed inorganic selenium. In conclusion, the organic selenium feed supplement can promote production performance and immune parameters of broilers.

Abstract

Sumba Ongole (Bos indicus) is a native beef cattle that adapts well in Sumba Island of Indonesia. This study was carried out to perform a genome-wide association study for body weight (BW) and carcass weight (CW) in Sumba Ongole (SO) bulls. A total of forty-eight (n=48) SO bulls were used in this study. The data were collected from the slaughterhouse at Bogor City, West Java, Indonesia, and were analyzed using a genomic software of TASSEL 5.0 to obtain the best genetic marker. The result showed that the threshold Manhattan plot (-Log10P3) was used to select SNP markers for BW and CW in SO bulls. The two (2) SNP markers at BTA1, i.e., ARS-BFGL-NGS-3162 (CEP63 gene) and ARS-BFGL-NGS-78232 were significantly associated with BW and CW, respectively. Nonetheless, the genetic diversity in both SNP markers was low, with a PIC value of less than 0.30. In conclusion, the heterozygous TG bulls in CEP63 gene have higher CW than homozygous TT bulls.

Abstract

Green Tea Extract, or GTE, is a powerful antioxidant that can be added to the extender to maintain the quality of Bali bull semen before and after freezing. This study aimed to evaluate the impact of the GTE addition in the extender on the sperm kinematic and sperm morphology from frozen semen of Bali bull. Five Bali bulls from the NAIC, were used as semen sources. In this study, there were four different treatments: a control (Tris-egg yolk without GTE), a GTE0.05 (100 mL tris egg yolk with 0.05 mg of GTE), a GTE0.10 (100 mL tris egg yolk with 0.10 mg of GTE), and a GTE0.15 (100 mL tris egg yolk with 0.15 mg of GTE). A sperm analyzer (CASA) was used to observe the sperm kinematics and morphology. Compared to the control group, adding different concentrations of GTE to the semen extender did not affect the sperm’s morphology. Before freezing, adding GTE0.05 increases total and progressive motility as well as VAP, VCL, and VSL after thawing. GTE0.15 increases STR and ALH. The conclusion is that GTE additions at doses of 0.05 mg/100 mL and 0.15 mg/100 mL can increase sperm kinematics parameters, but sperm morphology is not affected by the GTE.

Abstract

Yogurt, with the addition of herbal ingredients can add efficacy and value of its benefits. Several studies have proven that cinnamon, aloe vera, and fenugreek seeds have properties as antidiabetic and hypolipidemic. The purpose of this study was to evaluate the antidiabetic and hypolipidemic potential of yogurt with the addition of a combination of two or three types of herbal extracts, such as cinnamon, fenugreek seeds, and aloe vera, in diabetic rats. Diabetic rats were divided into six groups and given treatment for 21 days. Rats’ blood was taken to test blood glucose levels using glucometers, insulin with the ELISA method, blood lipid profiles, and kidney and liver functions using a chemistry analyzer. The data were statistically analyzed using one-way ANOVA followed by the Duncan test. The results showed that yogurt added with several combinations of herbal extracts such as cinnamon, aloe vera, and fenugreek seeds (III, IV, V, and VI) could significantly reduce blood glucose levels, increase insulin levels, improve lipid profiles, and improve kidney and liver functions in diabetic rats, as well as commercial administration of glibenclamide (II). Diabetic rats given yogurt with the addition of a combination of 3 herbal extracts (VI) and a combination of 2 herbal extracts (cinnamon +fenugreek seeds) (V) of 1% each showed better antidiabetic and hypolipidemic performances compared to the other groups (III, and IV). The combination of yogurt with some herbal extracts can add efficacy and value to the benefits of yogurt as a functional drink.
