Sixty sheep, twenty each breed, Balami, Uda, and Yankasa, with 24.7 ± 3.5, 25.5 ± 3.6, and 25.5 ± 3.5 kg average body weight, respectively, and 8-months-old were assigned in a factorial arrangement of 2 (hay) × 3 (breeds) from a complete randomized design. Sheep remained individually in cages for the metabolism assay and were fed either of the hays ad libitum and a feed concentrate at a level equivalent to 1% of their body weight for ninety days. Daily records of feed intakes were made, and blood and ruminal fluid were collected every two weeks. There was no significant (p > 0.05) interaction effect between breed and hay type on feed intake, ruminal parameters and blood metabolites. Balami breed presented a higher (p < 0.05) feed intake, rumen pH, NH₃-N, and blood concentration of creatinine, albumin, globulin, and glucose than Yankasa. The blood concentrations of creatinine, urea, albumin, total protein, globulin, and glucose were significantly (p < 0.05) greater in the Nigerian Uda sheep breed than in Balami and Yankasa. Sheep fed D. smutsii hay had higher (p < 0.05) intake of dry matter, crude protein, and NH₃-N than B. decumbens hay diets. However, there was no difference (p > 0.05) between hay types to NDF intake and ruminal pH. Sheep fed D. smutsii hay presented (p < 0.05) higher amounts of creatinine, urea, albumin, total protein, globulin, and glucose than B. decumbens hay diets. Nigerian Balami and Uda sheep breed presents higher intake and blood metabolite concentrations than the other two breeds, which may be associated with these animals' higher (p > 0.05) nutritional requirements. In addition, Digitaria smutsii hay provided higher dry matter and crude protein intake, NH₃-N, and blood concentrations, which may be associated with its better nutritional value for sheep, thus being a more suitable hay for feeding the Uda breed.</p>","PeriodicalId":23329,"journal":{"name":"Tropical animal health and production","volume":"57 7","pages":"339"},"PeriodicalIF":1.7,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144785436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 137 farmers were surveyed with majority aged 41-50, having 6-20 cattle. Education-wise, most of the farmers had high school or college education. Land holding patterns showed majority of farmers have small farms. Farmers preferred high-yielding exotic breeds. Participants observed ticks on livestock, grasses, and forest areas. Ticks were reported in warm and cold regions, affecting cattle productivity. Farmers showed mixed awareness on tick-borne diseases and management practices. Majority of farmers use good material for making the floor and roof of cattle shed, while few use conventional sheds. Acaricides, medicine, and deworming drugs are procured from government livestock centres with minimal charges. Different protocols of acaricide use were followed for acaricide administration. The fallen ticks after acaricidal treatments were managed differently and manual removal and herbal remedies were preferred methods for tick removal in the event of non-availability of acaricidal drugs.Farmers demonstrated a moderate understanding of tick control, but their management practices could be improved, especially through the adoption of integrated pest management (IPM) approaches. It is recommended to enhance farmer education on tick-borne diseases and encourage more regular use of acaricides alongside improved tick control methods.Compared to other KAP surveys; this study highlighted a stronger reliance on chemicals and a notable knowledge gap regarding disease transmission.</p>","PeriodicalId":23329,"journal":{"name":"Tropical animal health and production","volume":"57 7","pages":"342"},"PeriodicalIF":1.7,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144785432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two strategies were tested to enhance P4 concentrations and conception rates in cows with a low BCS. After TAI (Day 0), 863 cows were assigned to three groups: P4LA (n = 281; 150 mg long-acting progesterone injection on Day 7), GnRH (n = 285, 10 µg buserelin acetate on Day 7), and control (n = 297; no supplementation). Ultrasound assessments were performed on Day 0 and Day 7, and the cows were classified as high (BCS ≥ 3; n = 160) or low (BCS < 3; n = 101). No significant differences were observed in the POF or CL characteristics between the BCS groups. However, ovulation rates (P = 0.04) and P4 concentrations on Day 7 (P = 0.02) were higher in cows with high BCS. On Day 16, P4 concentrations were not different between high-BCS cows and those treated with GnRH or P4LA (P = 0.16). Among the low-BCS cows, the P4LA group had higher P4 concentrations than the control group (P = 0.04). In the control group, cows with low BCS had lower P4 concentrations than those with high BCS (P = 0.02). The conception rates of the low-BCS cows were lower in the control group than in the treatment group (P = 0.01).

We aimed to identify genomic regions and candidate genes associated with the ribeye area (REA), marbling (MARB), backfat thickness (BFT) and rump fat thickness (RFT). All phenotypes were recorded using real-time ultrasound. The pedigree file contained data for 2,446 animals and a total of 1,391 animals were genotyped with the GGP Bovine 150 K (Illumina). The single-step approach for genome-wide association study (ssGWAS) was performed to estimate the single nucleotide polymorphism (SNP) effects and variances accounted by 10-SNP sliding windows. Were identified for REA, MARB, BFT and RFT, respectively, 23, 23, 22, and 31 genomic windows that explained more than 0.5% of the additive genetic variance. Several protein-coding genes were identified within those genomic regions: MAMSTR, CTNNA3, AGAP1 and CDH6, located on 18:55.35-55.36, 28:22.29-24.12, 3:11.50-11.56 and 20:42.35-42.35 Mb, respectively.
