Individual 90-day body weight data were collected from 687 rabbits representing 61 sire and 194 dam families from a randomly mating population in tropical Ghana, West Africa. The population was based on crosses made between 1972 and 1984 involving 15 imported breeds with the local strain. Two consecutive generations (born in 1989 and 1990) of rabbits were analyzed by mixed model procedures. Approximations of restricted maximum likelihood estimates of the observational variance components corresponding ...

The effects of dietary protein and phosphorus level, and phytase and/or xylanase addition on performance, nutrient digestibility and energy metabolism in finisher pigs were determined. Protein reduction increased nutrient digestibility, pig performance and dietary net energy. Phosphorus reduction increased heat production, and tended to negatively affect all parameters. Phytase increased daily gain and dietary metabolizable energy. Xylanase improved digestibility of nutrients and energy, but had ...

A multi-channel thermal activity monitor was applied to study soil microbial activity in Wuhan brown sandy soil in the presence of different concentrations of hexavalent chromium (K2Cr2O7). In order to stimulate the soil microbial activity, 5.0 mg of glucose and 5.0 mg of ammonium sulfate were added to a 1.20-g soil sample under a controlled humidity of 35%. The results show that the poisonous species of K2Cr2O7 at an half inhibitory concentration (IC50) value of 4.27μgmL-1 against soil microbe, and ...

Reducing the crude protein (CP) content in pig diets changes its dietary C and fiber content and fiber composition, and may affect CH4 and CO2 produced by the pigs. The objective was to study effects of decreasing CP concentration on CH4 production, C retention efficiency and performance by finisher pigs. Four diets were formulated being: conventional (HP) and CP reduced, amino acid supplemented diets (MP), based on either corn grain/soybean meal (CS) or barley grain (BB). Twelve female pigs were assigned ...

Most of the grass savannas on lateritic crusts found in the North-Western of Benin are free of trees and a shrub layer is only sparsely developed. The only constant member of the shrub layer is Terminalia laxiflora. Intermediate constancy show Entada africana and Annona senegalensis. With regard to the herbaceous layer two types can be identified: On very shallow soils (<2 cm) Loudetia togoensis is highly constant and often dominating. The same is true for Andropogon pseudapricus on soils of a little ...

Insecticide protection at the vegetative, reproductive or both vegetative and reproductive (complete) crop growth stages and untreated control was used to assess yield loss due to insect pests at the different growth stages of soybean in Ghana from 2007–2009. The objectives were to determine the economic importance of the two major insect pest guilds in soybean, viz. defoliators and pod feeders, and when to apply control measures for maximum benefit. The defoliators recorded were Podagrica spp., ...

Market-age weight was recorded for 1,616 rabbits from 336 litters (sired by 121 bucks and reared by 321 does). Additional growth and carcass traits measured in control (C) and select (S) lines were 28-d weaning weight (WW), 28- to 70-d average daily gain (ADG), carcass yield percentage (CY), loin primal cut percentage (LP), and lean-to-bone ratio in the loin ...

SUMMARY Cowpea (Vigna unguiculata L. Walp) is the most important food grain legume in Africa. Cowpea is nodulated by rhizobium bacteria in almost all soils of the tropics, but studies performed in the 1970s and 1980s in Nigeria suggested only modest responses of grain yield in the field to inoculation of selected rhizobium strains. More recently, experiments performed in Brazil have shown that cowpea responded to inoculation of rhizobium selected locally and grain yields increased by up to 30%. We ...

Water-related activities that allow skin exposure place people at risk, but public health practitioners know little about why some communities with access to improved water infrastructure have substantial surface water contact with infectious water bodies.

The data demand for 5G networks is expected to be much higher than current throughput requirements. To meet this demand, a dense topology of interlinked small cells is needed. Laying new copper and fiber in such a dense network would be cost prohibitive. There is, therefore, an urgent need for high capacity wireless point-to-multipoint backhaul solutions. In this paper, we provide a compendium of solutions for ultrahigh data rate physical-layer broadcast and multicast using free space optics in ...

Background: Human milk contains many bioactive components that are typically studied in isolation, including bacteria. We performed an integrated analysis of human milk oligosaccharides and fatty acids to explore their associations with milk microbiota. Methods: We studied a sub-sample of 393 mothers in the CHILD birth cohort. Milk was collected at 3-4 months postpartum. Microbiota was analysed by 16S rRNA gene V4 sequencing. Oligosaccharides and fatty acids were analysed by rapid high-throughput ...

Abstract Background In recent years, the microbiome field has undergone a shift from clustering-based methods of operational taxonomic unit (OTU) designation based on sequence similarity to denoising algorithms that identify exact amplicon sequence variants (ASVs), and methods to identify contaminating bacterial DNA sequences from low biomass samples have been developed. Although these methods improve accuracy when analyzing mock communities, their impact on real samples and downstream analysis of ...

Groundnut yields obtained by farmers in northern Ghana are generally low due to low soil fertility resulting from continuous cropping coupled with low use of external inputs. There is therefore the need to use systems’ internal resources such as biological nitrogen fixation efficiently to enhance crop production. This on-station experiment investigated nodulation and pod yield responses of three groundnut varieties, namely Obolo, Oboshie and Samnut 22 to inoculation with rhizobium inoculants of ...

Sub-Saharan Africa (SSA) faces chronic food insecurity associated with soil degradation and the peculiar aftermath of climate change and exacerbated by rising population and historically poor agricultural practices. Notably, use of mineral fertilizers has the potential to counteract soil degradation in SSA; it drives an increased agricultural production required to feed the rising population while sustaining the quality and health of soils. However, limited financial resources deprive SSA of the ...
