ABSTRACT   Two feeding trials were conducted to evaluate the effect of sweet potato and sweet potato peel meals on the growth and laying performance of Japanese quails (Coturnix coturnix japonica). One thousand Five hundred and six Japanese quails were used for the study. In experiment 1, three hundred mixed sexes of 2 weeks old […]

ABSTRACT Two studies were conducted to determine growth and fattening performance of Yankasa rams fed complete containing urea and lime treated groundnut (Arachis hypogaea) shell. The shell was treated with 5% urea, 5% lime and 2.5% of urea and lime for each known weight of the shell (50g/kg shell). In the first study four treatment […]

ABSTRACT Sunflower is an important oilseed crop due to its health related values. Induced mutations are often used to create new genetic variability where sufficient variation does not exist naturally as in the case of sunflower. This study was carried out at the laboratory and research farm of the Institute for Agricultural Research (IAR), Samaru, […]

ABSTRACT Groundnut (Arachis hypogaea L.) is one of the major crops susceptible to Aspergillus flavus infection and subsequent aflatoxin contamination which adversely affects its production and utilization in the small holder setting. Although there are several management strategies that may reduce aflatoxin contamination of groundnuts, the pre-eminent strategy for the prevention of aflatoxin is to […]

ABSTRACT A preliminary study was carried out to determine the prevalence of Aflatoxin B1 (AfB1) contamination and common moulds growing in some selected poultry feed ingredients in Zaria town, Nigeria. Twenty-five (25) samples of five different feed ingredients, which included Maize (MZ), soybean cake (SBC), groundnut cake (GNC), brewers dried grain (BDG) and maize offal […]

ABSTRACT   A 16-week study was conducted to evaluate the effect of biostimulation on behaviour, growth, and reproduction of rabbits. Seventy five (crossbreds) mature rabbits (2.6 -2.70 kg), comprising of 50 nulliparous does aged, 6-7 months old and 25 bucks, (8-10 months old), were used for this study. The rabbits were allocated into five treatment […]

Abstract   A study was conducted to evaluate the effects of thermal indices and relationship with milk yield in dairy cows using invasive (glucose, total cholesterol, triiodothyronine (T3), thyroxine (T4), aspartate aminotransferase (AST), alanine aminotransferase (ALT) and inorganic phosphate) and non-invasive (Rectal temperature (RT), respiration rate (RR), ear temperature (ET) and skin temperature (ST) markers […]

Abstract   A long-term field experiment was established in 2003 at the Institute for Agricultural Research, (I.A.R) Samaru, northern Guinea savanna of Nigeria to evaluate the effect of N fertilizer on maize grown in rotation with maize, cowpea and soybean. The trial was modified to accommodate tillage as an additional experimental factor in 2009. Ten […]

ABSTRACT Land use changes from forest into cultivated ecosystems result in negative impact on soil structure and quality. The purpose of this study was to determine effect of land use and slope on selected properties and quality of an Alfisol in Afaka forest, Northern Guinea savanna of Nigeria. Land use systems, including natural forest and […]
