Preliminary empirical review revealed that herbal extracts enhanced immune parameters, such as lymphocyte proliferation and cytokine production, suggesting their potential to improve poultry health and disease resistance. The diverse mechanisms of action of phytochemicals underscored the complexity of herbal supplements' effects on poultry immunity, while considerations such as formulation and environmental factors influenced their efficacy. Overall, while further research is warranted to optimize formulations and deepen our understanding of mechanisms, herbal supplements show considerable promise as alternatives to conventional additives in poultry production, offering holistic and sustainable approaches to enhancing poultry health and welfare. \u0000Unique Contribution to Theory, Practice and Policy: The Systems Biology theory, Ecological Systems theory and Ethnopharmacology theory may be used to anchor future studies on immunomodulatory effects of herbal supplements in poultry. The study provided recommendations that contributed to theory, practice, and policy in poultry production and animal health. The findings advanced theoretical knowledge by elucidating the complex interactions between phytochemicals and the avian immune system. In practice, recommendations supported the incorporation of herbal supplements into poultry diets to promote immune health and disease resistance, benefiting poultry producers, veterinarians, and feed manufacturers. Moreover, policy recommendations advocated for regulatory frameworks supporting the use of herbal supplements and education initiatives aimed at enhancing stakeholder awareness and understanding.

Preliminary empirical review revealed that that enriching their living environments significantly improved their well-being. They found that interventions such as physical, social, cognitive, and sensory enrichment reduced stress levels, promoted natural behaviors, and enhanced cognitive function. Tailoring enrichment programs to specific species' needs and considering factors like environmental complexity and novelty proved crucial. Moreover, these interventions not only benefited animal welfare but also improved research outcomes by reducing stress and enhancing the validity of preclinical studies. Overall, the research underscored the importance of implementing evidence-based enrichment strategies to ensure the ethical treatment of laboratory animals and enhance the reliability of scientific research. \u0000Unique Contribution to Theory, Practice and Policy: The Biophilia Hypothesis, Optimal Stimulation theory and Stress Inoculation theory may be used to anchor future studies on stress and welfare in laboratory animals.

Methodology: The study covered 108 primiparous does and nine bucks from Sahel (SH), Red Sokoto (RS), and West African dwarf (WAD) goat breeds. In different pens, the animals were bred in various combinations: RS x RS, WAD x WAD, SH x SH, RS x SH, RS x WAD, SH x RS, and SH x WAD. WAD x SH, WAD x RS. Estrus synchronization was done using prostaglandins. Mating occurred naturally when animals were on heat. Dams were given special care throughout pregnancy. The study measured dams' weights, litter size, and pre-weaning mortality rates in kids. The total kid crop and sexes were also assessed. We measured dam lactation weight loss, birth weight, and weaning weight. SPSS, ANOVA, and the Turkey statistical test were used for data analysis. Findings: The result showed that there was a significant (P<0.05) difference in the weight of does at kidding. The weight of does at weaning varied significantly (P<0.05). Litter size significantly (P<0.05) affected the birth weight and weaning weight of kids. An increase in litter size per birth resulted in a significant (P<0.05) rise in kid mortality rates. Breed type significantly (P<0.05) affected doe production efficiency and weaning weight ratio. Although WAD x WAD goats had lower birth and weaning weights, hybrid vigour (birth and weaning weights) improved significantly (P<0.05) when cross-bred with SH or RS breeds. When crossed with SH or WAD goat breeds, RS breeds had the greatest positive effect on hybrid vigour (heterosis), followed by SH breeds. Both SH x RS and RS x SH progenies recorded higher hybrid vigour than the other nine bred line progenies. Unique contribution to theory, practice and policy: This study found that Nigerian indigenous goat breeds had great reproductive efficiency and breeding potential if properly managed. Genetic variations observed in the study could improve Kids crop, birth weight, litter size, hybrid vigour, and pre-weaning survivorship due to their broad variety. This study recommends a careful selection and crossbreeding of Nigerian indigenous goat breeds with suitable pedigree in order to increase their productivity.","PeriodicalId":439098,"journal":{"name":"Animal Health Journal","volume":"219 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139203529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
