Five growth studies and an ME study were performed to study the effects of replacing 0-80% of the maize fraction in broiler chicken diets with sorghum beer residue (SBR), The ME of the residue was determined to he 1764kcal/kg. The results of feeding trials obtained indicated that weight gains, feed efficiency were depressed with increasing levels ... Continue Reading
Forty-eight Sokoto Gudali bulls belonging to two age groups were used to study compensatory growth. The animals were fed either low (L), moderate (M) or high (H) plane of nutrition during three periods. The feeding periods were arranged to give LLH, LMH and LHH feeding regimes. Feed intake, growth, physiological parameters and body compositional ch... Continue Reading
Taxation is not new in the scene of human existence as it has been part of it all along. However, despite its age long history, its importance and necessity, it has not received the required level of acceptance and compliance. Instead, people tend to avoid the payment of tax if they are not compelled to do so. The trend is worse among operators in ... Continue Reading
Two separate studies to evaluate alternative methods of processing Acacia nilotica pods and level of replacement of cotton seed cake with Acacia pods; and its effect on nutrient composition, feed intake, digestibility of nutrients, heamatological parameters and general performance of Red Sokoto goats were conducted. The aims were to explore cheape... Continue Reading
Field experiments in 1979 revealed that higher populations of Metopolphium dirhodum (Wlk.) developed on barley yellow dwarf virus (BYDV)-infected winter wheat and oats than on healthy plants. More Sitobion avenae (L.) were similarly recorded in 1980 on BYDV-infected winter wheat, oats and barley. In both years, foci of BYDV infection attracted more... Continue Reading
Data on the monthly egg production of 2 strains (A and B) of Rhode Island chickens (500 breeder hens per strain) were used to test the goodness of fit of six mathematical models, viz; Exponential, Parabolic exponential. Wood's Gamma and modified Gamma by McNally, Inverse polynomial and Linear regresion. Egg production was summarised for each hen in... Continue Reading
A design procedure was developed for border irrigation based on the need to have very high efficiencies of water distribution while at the same time maintaining an acceptable degree of water application efficiency. The water application efficiency for the design was estimated from the analysis of a border strip in which a cut back flow was not used... Continue Reading
Two experiments were designed to study crop mixtures involving maize and pepper. Seedling age treatments were also included. In 1980 at Dangora, pepper was mixed with maize and cowpea planted in the sequence maize-peppercowpea under rainfed condition. Three maize spacing treatments of 360, 270 and 180cm. were used. In 1981 at Samaru, pepper was int... Continue Reading
Due Co the oxytetracycline's usefulness and availability, its effect in a local food animal (Chicken: Gallus domesticus L) was investigated, and the residual drug level in the tissues, assessed. Seventy-two young broiler-type chick (of both sexes) were used for the experiment. They were herded in batches of 12 as groups A - F. The groups were given... Continue Reading
Studies on the resistance of wheat to two cereal aphids (Sitobion avenae and Metopolophium dirhodum) were carried out in the glasshouse using some ancient wheats (Einkorn, Emmer and Spelt) as well as some modern wheat varieties (Bounty, Highbury, Mardler and Maris Kinsman). The diploid ancient wheat Einkorn was the least preferred by both cereal ap... Continue Reading
Three studies were conducted to evaluate the utilization of rice mill by-product using soyabean meal and groundnut cake as protein supplements in the diets of pigs. In the first trial, eighteen (18) crossbred (Large White X Landrace) pigs with average initial weight of 35.9 kg were fed rice by-product at 0, 5 or 10 percent of the 15 percent crude p...

In an attempt to find a substitute for Nemagon five nematicides were tested for the control of rootknot nematodes on tomato. Mocap was quite effective in root-knot control in nursery seedlings but phytotoxicity was observed when applied at dosages equal to or higher than 10 kg a.i per hectare, the dosage recommended by the manufacturer. Although N... Continue Reading
This study investigated the suitability of the available models in representing the pattern of milk production of Bunaji, Friesian and Friesian-Bunaji crossbred cows in Nigeria. The models evaluated were Gamma, Modified Gamma and the Inverse Polynomial functions. Five hundred and eighty-four lactations were used. These comprised of 205, 111 and 268... Continue Reading
The main aim of the study was to determine the least cost ration and optimum marketing weights for broiler chicken when groundnut meal is the main sources of protein in the broiler finisher ration. The data for the analysis was obtained from the National Animal Production Research Institute, Shikao The data was from experiments that covered aspect ... Continue Reading
Broiler chicks were fed diets containing 0, 10, 20, 30, 40 or 50% sunflower seed (SFS) during the starter and finisher phases. Increase in dietary level of SFS above 20% caused a significant decrease in feed intake, weight gain and increase in feed conversion ratio (P<0.05) during the starter phase(0-4 weeks). During the finisher phase(5-8 weeks), ... Continue Reading
