Abstract: This work briefly reviews the nutritional significance of silicon and calcium for human health. The study also highlights the harmful impacts associated with exposure to silica nano-particles and chemical alterations caused by water acidification. Acidification which results from expel of carbon dioxide to the seawater can both directly and indirectly affect the human health through intensifying the levels of exposure to chemicals compounds and trace metals as well as through altering the bioavailability of pollutants and bioaccumulation.

Keywords: acidification, silicon, calcium, human body, bioavailability.

Abstract: The poultry industry plays a vital role in meeting the growing global demand for animal protein. Genetic improvement of chicken strains is crucial to enhance production efficiency.

This study investigates the genetic variations in Prolactin (PRL) and its potential associations with growth traits in two distinct chicken strains, Broilers (Cobb 500) and Noilers.

To achieve this, a total of 200 day-old chicks comprising 100 Cobb 500 and 100 Noiler strain of mixed sex were used for the experiment. The study was carried out for a period of eight weeks with the birds distributed into pens based on strain and sexes into twelve treatments (17 birds per pen), genomic DNA samples were collected from the hypothalamus, breast, liver and spleen of both broiler and noiler chickens. Polymerase Chain Reaction (PCR) amplification and sequencing techniques were employed to analyse the PRL genes in the different tissues. The result revealed a significant effect (p<0.05) in all tissues except the liver. Notably, higher PRL values were recorded for female Cobb 500 in the liver and hypothalamus and female Noiler in the breast. These findings underscore the strain-specific regulation of PRL expression and highlight distinct gender-associated patterns in different tissues.

Subsequently, growth performance traits, including body weight, feed conversion, and linear measurements were measured in the two strains. Results indicated superior growth performance in Cobb 500 compared to Noiler chickens, with higher final weights observed in the former.

This study sheds light on the genetic underpinnings of growth traits in broiler and noiler chickens, offering valuable insights into potential avenues for selective breeding programs aimed at optimizing poultry production. Understanding the genetic basis of growth traits is pivotal for developing sustainable and economically viable chicken strains, ultimately contributing to the global food security challenge.

Abstract: Most developed countries have achieved their status through industrialization, which involves shifting capital and labour from agriculture to manufacturing. Unfortunately, Kenya has experienced a decline in the contribution of manufacturing to its GDP, with the tea processing industry being particularly affected. Despite the government's efforts, including implementing the latest industrialization policy and vision for 2030, which specifically aimed to boost manufacturing, the desired outcomes have proven elusive. In light of this challenge, the objective of this study was to investigate the relationship between road network efficiency and the performance of the tea processing industry in Kenya. The study drew upon resource dependency theory to provide a foundation for its investigation. The target population for the study consisted of 29,854 tea farmers in Murang'a County. From this population, a sample of 379 tea farmers was selected using quota sampling. Data for the study were collected through questionnaires, document analysis, and group interviews. The collected data were analyzed using descriptive measures, such as frequencies and percentages and inferential analysis utilizing Pearson's correlation. The results revealed a significant and strong positive relationship between road network efficiency and the performance of tea processing industries in Murang'a county (r = .759, p = .001 at α = .05). Based on these findings; the study recommends that both the county and national governments make significant investments in road network infrastructure to enhance the performance of the tea processing industry to meet international standards.

Keywords: Road Network efficiency, Performance and Tea Processing Industries.
