“…It appears that the increase in the number of ruminant livestock populations (cattle and goat) Pinrang, 2022), so it has the potential to be developed (Thinnabut et al, 2023) and become one of the contributors to livelihoods in rural areas as producers of meat, milk and leather (King et al, 2022).…”

“…follows the livestock performance equation, namely In (Y) = -348.47 + 0.18t with a growth rate for cattle of 18% and In (Y) = -340.38 + 0,17t with a growth rate of 17% for goat. During the last three years, the cattle population has grown by 19,29% and goats by 4,22% in Watang Sawitto District, Pinrang Regency (Badan Pusat Statistik Kabupaten Pinrang, 2022), so it has the potential to be developed(Thinnabut et al, 2023) and become one of the contributors to livelihoods in rural areas as producers of meat, milk and leather(King et al, 2022).Agricultural and livestock development is a priority to stimulate overall economic growth and play a role in food security. Livestock populations can increase or decrease due to the effects of death from disease(Brock et al, 2021) or the sale…”

This study aims to determine the characteristics of farmer groups, rice plant waste production, livestock performance, livestock economic density and feed concentration index in Salo Urban Village. This study uses a descriptive cross-sectional research design. Data were analyzed to look at the characteristics of farmer groups according to sex and age, rice plant waste production, livestock performance, livestock economic density and feed concentration index in Salo Urban Village. The results showed 23 farmer groups with 1.077 members, 937 male (87%) and 140 female (13%). There were 2 categories: the productive category for those aged 15 - 64 years old (85,24%) and the unproductive category for those over 65 years old (14,76%). The average harvested area is 39,18 Ha/farmer group; with fresh production of rice plant waste being 465,80 tons; dry production of rice plant waste being 263,65 tons; and dry matter production being 233,49 tons. The livestock performance equation is In (Y) = -348.47 + 0.18t with a growth rate of 18% for cattle and In (Y) = -340.38 + 0.17t with a growth rate of 17% for goats, and has an economic density of livestock in the rarely category. The feed concentration index obtained three categories, namely the high production category (1 farmer group), the medium production category (6 farmer groups) and the low production category (16 farmer groups). Shows that rice plant waste harvested from farmer groups in Salo Urban Village can be used as a ruminant feed source.

Background The integration of molecular data from hosts, parasites, and microbiota can enhance our understanding of the complex biological interactions underlying the resistance of hosts to parasites. Haemonchus contortus, the predominant sheep gastrointestinal parasite species in the tropics, causes significant production and economic losses, which are further compounded by the diminishing efficiency of chemical control owing to anthelmintic resistance. Knowledge of how the host responds to infection and how the parasite, in combination with microbiota, modulates host immunity can guide selection decisions to breed animals with improved parasite resistance. This understanding will help refine management practices and advance the development of new therapeutics for long-term helminth control. Methods Eggs per gram (EPG) of feces were obtained from Morada Nova sheep subjected to two artificial infections with H. contortus and used as a proxy to select animals with high resistance or susceptibility for transcriptome sequencing (RNA-seq) of the abomasum and 50 K single-nucleotide genotyping. Additionally, RNA-seq data for H. contortus were generated, and amplicon sequence variants (ASV) were obtained using polymerase chain reaction amplification and sequencing of bacterial and archaeal 16S ribosomal RNA genes from sheep feces and rumen content. Results The heritability estimate for EPG was 0.12. GAST, GNLY, IL13, MGRN1, FGF14, and RORC genes and transcripts were differentially expressed between resistant and susceptible animals. A genome-wide association study identified regions on chromosomes 2 and 11 that harbor candidate genes for resistance, immune response, body weight, and adaptation. Trans-expression quantitative trait loci were found between significant variants and differentially expressed transcripts. Functional co-expression modules based on sheep genes and ASVs correlated with resistance to H. contortus, showing enrichment in pathways of response to bacteria, immune and inflammatory responses, and hub features of the Christensenellaceae, Bacteroides, and Methanobrevibacter genera; Prevotellaceae family; and Verrucomicrobiota phylum. In H. contortus, some mitochondrial, collagen-, and cuticle-related genes were expressed only in parasites isolated from susceptible sheep. Conclusions The present study identified chromosome regions, genes, transcripts, and pathways involved in the elaborate interactions between the sheep host, its gastrointestinal microbiota, and the H. contortus parasite. These findings will assist in the development of animal selection strategies for parasite resistance and interdisciplinary approaches to control H. contortus infection in sheep. Graphical Abstract

Background: The integration of molecular data from hosts, parasites, and microbiota can enhance our understanding of the complex biological interactions underlying parasite resistance. Haemonchus contortus, the predominant sheep parasite species in the tropics, results in significant production and economic losses, which are further compounded by the diminishing efficiency of chemical control measures due to anthelmintic resistance. Knowledge of how the host responds to infection and how the parasite, in combination with microbiota effects, modulates host immunity can guide selection decisions to breed more resistant animals. This understanding can also refine management practices and inform the development of new therapeutics for long-term helminth control. Results: Egg per gram (EPG) counts were obtained in Morada Nova sheep subjected to two artificial infections with H. contortus, and used as a proxy to select animals with high resistance or susceptibility. The GAST, GNLY, IL13, MGRN1, FGF14, and RORC genes and transcripts were differentially expressed between groups based on RNA-seq of the abomasum. From 50K SNP genotyping, EPG heritability estimate was 0.12, and a genome-wide association study (GWAS) identified regions on chromosomes 2 and 11 harboring candidate genes for resistance, immune response, body weight, and adaptation. Trans-eQTLs between significant variants and differentially expressed transcripts were found. Amplicon sequence variants (ASVs) from PCR amplification and sequencing of bacterial and archaeal 16S rRNA genes in sheep feces and rumen generated functional co-expression modules correlated with resistance to H. contortus, showing enrichment in pathways of response to bacterium, immune and inflammatory responses, and hub features of the Christensenellaceae, Bacteroides, and Methanobrevibacter genera, Prevotellaceae family, and Verrucomicrobiota. In RNA-seq of H. contortus, some mitochondrial, collagen- and cuticle-related genes were expressed only in parasites retrieved from susceptible sheep. Conclusions: This study identified chromosome regions, genes, transcripts, and pathways involved in the elaborate interactions between the sheep host, its gastrointestinal microbiota and the H. contortus parasite. These findings can assist with the development of animal selection strategies for parasite resistance and interdisciplinary approaches to control H. contortus in sheep.
