Abstract:

The experiment was conducted to evaluate the effects of replacing 0, 25, 50, 75 and 100 % levels of maize in broiler diet with white guinea corn on the growth performance of broiler birds at starter and finisher phases of production. Substituting maize with white guinea corn did not adversely (p > 0.05) affect feed intake across the dietary treatments at both the starter and finisher phases of the study. At the starter phase, birds fed 25 % and 50 % guinea corn as replacement for maize gave comparable results as those fed diet T<sub>1 </sub>(control). At the finisher phase, there was no sig

Abstract:

Maize and sorghum plays an important role in the diet of Africans, it serves as a major source of carbohydrate in both human and livestock diet for release of energy needed for normal body metabolism. In this research white maize and white sorghum (Guinea corn) both of the grass family were analysed for their proximate contents. The maize and sorghum (Guinea corn) were found to be nutritious both contained carbohydrate, protein, fats and oil, crude fibre content and minerals (Ash). In the research carried out it was found that maize contained moisture content of 7.16%, Protein 8.75%, Fats and

This study investigated the effects of substituting maize grain with alternative energy sources (white Guinea corn, cassava flour, and sweet potato flour) on the growth performance, feed intake, serum biochemistry, and sensory attributes of Marshal Broilers. The research addressed the challenge of fluctuating availability and rising costs of maize, a key poultry feed component. Four dietary treatments were tested over an eight-week period with 400 day-old Arbor Acres broiler chicks, divided into four groups of 100 birds each.

This compound is 10 times more potent when compared with 4-AP and other derivatives in restoring axonal conduction. Unlike 4-AP, 4-AP-3-MeOH can restore axonal conduction without changing axonal electrophysiological properties.

It was shown previously that when a polarized (rostrally negative), weak (300–400 μV/mm) DC electric field is placed across a lateral hemisection of the spinal cord in adult guinea pigs at the time of injury, approximately 13% recover the reflex, while sham-

Consideration on High Performance Concrete (HPC) has risen drastically because of the requirement for application of concrete volume with high strengths for construction work. In this study, the mechanical properties of HPC with Guinea Corn Husk Ash (GCHA) as supplement of cement was investigated. The proportioning of Ordinary Portland Cement (OPC) with GCHA is from 0 - 20%. Design of the concrete mix was done to achieve a characteristic strength of 50 N/mm². The chemical composition of the GCHA was determined using X-ray Fluorescence (XRF) Slump and compacting factor of fresh HPC were determi

This study examined the impact of US Africa Command on maritime security in the Gulf of Guinea in West Africa, between 2007 and 2020, with specific emphasis on the core maritime security challenges in West Africa. The study was anchored on the World Systems Theory, while data were generated using documentary and survey methods. Data collected were analysed using content analysis. The study found that maritime security challenges in West Africa include piracy, armed robbery, and drug trafficking. It also found that maritime insecurity has remained endemic in the Gulf of Guinea, despite the esta

Abstract:

Acute repair of crushed guinea pig spinal cord by polyethylene glycol. We have studied the responses of adult guinea pig spinal cord white matter to a standardized compression within a sucrose gap recording chamber. This injury eliminated compound action potential (CAP) conduction through the lesion, followed by little or no recovery of conduction by 1 h postinjury. We tested the ability of polyethylene glycol (PEG) to repair the injured axons and restore physiological function. Local application of PEG (1,800 MW, 50% by weight in water) for ∼2 min restored CAP conduction through the injury as

Abstract:

Salmonella enterica subsp. enterica serovar Typhimurium (S. Typhimurium) is one of the most important foodborne pathogens that infect humans globally. The gastrointestinal tracts of animals like pigs, poultry or cattle are the main reservoirs of Salmonella serotypes. Guinea pig meat is an important protein source for Andean countries, but this animal is commonly infected by S. Typhimurium, producing high mortality rates and generating economic losses. Despite its impact on human health, food security, and economy, there is no genomic information about the S. Typhimurium responsible for the gui

Abstract:

Axonal conduction deficit is a major contributor to various degrees of disability after spinal cord injury. 4-aminopyridine (4-AP), a potassium channel blocker, has been shown to restore some conduction and improve neurological function in both animal and human studies. Using a double sucrosegap recording device, we have examined the effects of 4-AP on isolated guinea pig spinal cord white matter after stretch injury. At a concentration of 100 μM, 4-AP increased the amplitude of the compound action potential by 100% while 1 μM 4-AP increased it by 43%, a larger response than seen following com
