This study examined the determinants of smallholder dairy farmers' use of breeding services in Nyandarua and Kiambu districts, Central Kenya. Data was collected through semi-structured interviews with 140 randomly selected respondents. The breeding services considered were artificial insemination (AI), natural bull service, or a combination of AI and bull services. A multinomial logit econometric model was used fitting AI as the base category. There was a negative relationship between higher levels of education, herd size, and location and the use of bull service. However, education, herd size, and credit were positively related to the combined option. The results indicate that uptake of AI services after the liberalization of the sector is influenced by other factors besides cost-related factors. Factors such as accessibility to breeding services and product markets had influence on the farmer decision to choose among the available breeding services. The effectiveness of the breeding services in terms of successful conception also plays a big role in the choice. A need for concerted efforts to increase farmer's knowledge base on utilization and effectiveness of available breeding services is imperative. Furthermore, smallholder dairy farming could be made more sustainable and economically viable by implementing initiatives geared towards enhancing access to breeding services that would guarantee access to quality genetic material.

The Influence of Migration Timing and Local Conditions on Reproductive Timing in Arctic-Breeding Birds.

For birds breeding in the Arctic, nest success is affected by the timing of nest initiation, which is partially determined by local conditions such as snow cover. However, conditions during the non-breeding season can carry over to affect the timing of breeding. We used tracking and breeding data from 248 individuals of 8 species and subspecies of Arctic-breeding shorebirds to estimate how the timing of nest initiation is related to local conditions like snowmelt phenology versus prior conditions, measured by the timing and speed of migration.

The Arctic environment plays a critical role in the global climate system and marine biodiversity. The region's ice-covered expanses provide essential breeding and feeding grounds for a diverse assemblage of marine species, who have adapted to thrive in these harsh conditions and consequently are under threat from global warming. The bearded seal (Erignathus barbatus), including two subspecies (E.

The motility of sperm decreases following cryopreservation, which is closely associated with mitochondrial function. However, the alterations in mitochondrial metabolism after sperm freezing in goats remain unclear. This experiment aimed to investigate the impact of ultra-low temperature freezing on goat sperm's mitochondrial energy metabolism and its potential correlation with sperm motility.

Background: Frequent interspecific hybridization, unclear genetic backgrounds, and ambiguous evolutionary relationships within the genus Lycoris pose significant challenges to the identification and classification of hybrids, thereby impacting the application and development of Lycoris. This study utilizes karyotype structure, genome size, and fluorescent in situ hybridization (FISH) technology to explore the chromosomal evolution and hybrid identification of Lycoris employing three approaches at the cytogenetic level.
Results: The findings indicate that species with a smaller basic chromosome number exhibit less asymmetry than those with a larger basic chromosome number, suggesting that species with different basic chromosome numbers may have followed different evolutionary pathways.

Glyphosate (Gly) is a widely used herbicide for weed control in agriculture, but it can also adversely affect crops by impairing growth, reducing yield, and disrupting nutrient uptake, while inducing toxicity. Therefore, adopting integrated eco-friendly approaches and understanding the mechanisms of glyphosate tolerance in plants is crucial, as these areas remain underexplored. This study provides proteome insights into Si-mediated improvement of Gly-toxicity tolerance in Brassica napus.
