Ecological implications of environmental contaminants on biodiversity and ecosystem services: The Nigerian Experience

This paper reviews the implications of environmental contamination on Nigerian biodiversity and ecosystem services aimed at identifying the causes, effects and remediation strategies. Literatures on concept of environmental contamination, biodiversity and ecosystem services were discussed. Environmental contaminants are known to be naturally occurring compounds, but anthropogenic activities introduce them in large quantities in different environmental compartments. This leads to the environme...

Environmental Influences on Animal Growth, Welfare And Reproduction

The environment plays a major role in the profitability of any livestock enterprise. Therefore, understanding how each environmental factor affects the growth, welfare and reproduction of animals is very important. When the influence that each environmental factor has on the growth, welfare and reproduction is known, the livestock producer can provide solutions that will mitigate the negative effects of these environmental factors on his livestock. The positive influence of any environmental ...

Comparison of conventional and automated freezing methods on PB2 rooster semen cryopreserved with glycerol and dimethylsulfoxide tris coconut-water extender

Background: Poultry semen cryopreservation remains an easy and promising way of preserving and transferring poultry germplasm. Standardizing and optimizing freezing procedure with natural extender may be a reliable step towards achieving better post-thawed sperm quality. This study was conducted to investigate the effects of four different freezing protocols (FP) on frozen rooster semen extended with tris coconut water extender (TCWE). A total of 20 roosters were used and trained for semen co...

SEX IDENTIFICATION OF NIGERIAN INDIGENOUS FRIZZLE FEATHERED AND NAKED NECK CHICKS USING VENT SEXING AND MOLECULAR TECHNIQUE

ABSTRACTSex  determination of  Nigerian indigenous  frizzle  feathered and naked neck chicks  has  been a difficult  task especially  due  to the  monomorphism  and high variation in  the  feather  colour  of  this indigenous  chickens  using  the  feather  sexing method. Thus, the  vent  sexing method is  cheap  and easy  to  carry  out  depending&n...

IMPACT OF NYPA PALM (Nypa fruticans Wurmb) AND MANGROVES ON THE PLANKTON AND BENTHIC COMMUNITIES OF THE RIVER ANDONI, NIGERIA.

ABSTRACT The impact of Nypa fruticans (Wurmb) and mangroves on the plankton and benthic communities of Andoni river was carried out between January and August, 2017. Four stations were chosen based on Nypa palm and native mangrove species’ presence and absence. Water quality parameters include; pH 6.99±0.16, Temperature 28.20±0.050C, D.O 4.71±0.18mg/L, Conductivity 19.52±0.20µm/s, Salinity 10.76±0.07ppt, TDS 13.45±0.27ppt.  Mean values of the physico-chemical param...

INTRASPECIFIC HYBRIDIZATION AND RECIPROCAL CROSS BETWEEN CULTURED AND WILD Clarias gariepinus; AND EVALUATION OF THEIR PROGENIES

AbstractStudies of intraspecific hybridization and reciprocal cross between cultured and wild Clarias gariepinus and evaluation of their progenies was carried out, with aim of evaluating the progenies of the crosses hatchability, survival, growth etc. Pure strains of cultured and wild Clarias gariepinus broodstock were used. Incubation, hatching, and post hatching activities were monitored in 50 litres plastic bowls. Cultured Male Clarias gariepinus (CCG♂) x Wild Female ...

Proximate and Macro Element Composition of Four Fish Species from Lower River Benue Makurdi Benue State Nigeria

A study was conducted on four fresh water fish species: Protopterus annectens, Labeo coubie, Auchenoglanis occidentalis and Mormyrus rume from lower river Benue, Makurdi to determine the proximate and macro elements composition of these fish species from lower river Benue Makurdi. A total of 600 fish samples were collected, 50 samples from each species for the period of three months. Fish samples were collected and transported to the University of Agriculture Makurdi, Department of Fis...

Determination of heavy metals in water and Clariasgariepinus from River Ngadda

Abstract  Water and fish samples were collected monthly from each of the four sampling Sites from August to September 2019 with the aid plastic bottles, hook and line and a gura trap from river Ngadda, Maiduguri, Borno state. A total of 16 fishes belonging to Clarias garipienus were sampled throughout the sampling periods. One fish from each station was dried before digestion and other was digested in its fresh form. The samples were transported to Soil Science Laboratory, Faculty of Agricul...

Emergence potential and growth characteristic of paliside grass (Brachiara murandu) as influence by different NPK fertilizer rate AT NAPRI, SHIKA

ABSTRACTThe experiment was conducted using Brachiara murandu (paliside grass) to determine the Emergence potential of Brachiara murandu as influence by different fertilizer rates in northern guinea savanna of Nigeria. The experiment consisted of six treatments NPK 0-0-0 Kg ha-1 (control),  NPK 20 Kg ha-1, NPK 40 Kg ha-1, NPK 60 Kg ha-1, NPK 80 Kg ha-1, and NPK 100 Kg ha-1. The treatments was replicated three time making up 18 plots, and assign using Complete Randomise Block Design (CRBD)...

Influence of Tamarind Pulp on Growth and Carcass Characteristics of Broiler Chickens

A study  was conducted to  determine the influence  of  an  aqueous  solution  of  tamarind  pulp  on  growth  and carcass characteristics of  broiler chickens.  One  hundred  and  sixty,  one  week  old broilers were  divided into  4 treatment  groups replicated  4  times in  a completely  randomized design.  The control  group  was  given  0g/L tamarind pulp (TP) while  the other groups  received 20g/L,  30g/L  and 40g/L  tamarind pulp in  drinking  wa...

THE IMPACT OF GOVERNMENT EXPENDITURE ON ECONOMIC GROWTH IN NIGERIA

The research observes that although rising government expenditure has relatively significant on economic growth. It has not translated to meaningful development as Nigeria still ranks among world's poorest counties. In an attempt to investigate the impact of government expenditure on economic growth, we adopted a dis-aggregated analysis using Ordinary Least Square (OLS) econometric methodology. The regression result shows that recurrent government expenditure, and capital government expe...

Sea Horse: A Case Study

INTRODUCTIONSeahorses (Hippocampus spp.) are among the many genera whose life histories might render them vulnerable to overfishing or other disruptions such as habitat damage. They are generally characterized by a sparse distribution, low mobility, small home ranges, low fecundity, lengthy parental care and mate fidelity (Foster and Vincent 2004). In addition, the male seahorse, rather than the female, becomes pregnant. Indeed, curiosity about this phenomenon explains why currently more is k...
