An experiment was carried out to evaluate the replacement value of local maize offal (dusa) in broiler starter and in finisher diets. The levels of inclusion of dusa were 0, 10, 20, 30, 40, 50, 52.43 and 0, 10, 20,30,40,50,63.98% for starter and finisher diets respectively. The results showed that from 0-4 weeks of age, there was no significant dif... Continue Reading
This work comprised four phases which were: 1. Fabrication of the steel mould. 2. Formulation of the mixture and moulding of the mixed components into blocks. 3. Physical testing of the blocks to determine their hardness and shearing properties. 4. Feeding trial using sorghum stover as basal diet and different types of graded level of molasses - ur...

Two sets of trials were conducted during the 1994 and 1995 dry seasons at Samaru in the Northern Guinea Savanna agro-ecological zone of Nigeria to study the effect of period of weed interference and chemical weed control on the growth and yield of garlic (Allium sativum L.). In the weed interference trials, weed infestation initially for 3 WAP did ... Continue Reading
Two field experiments were conducted during the 1986 wet season at Samaru in the northern Guinea savanna ecological zone of Nigeria to study the effects of mulching, periods of weed interference and chemical weed control ginger (Zingiber officinale Roscoe). In the weed interference trial, the use of grass mulch resulted in lower weed infestation an... Continue Reading
A study was conducted to determine genetic and phenotypic parameters of reproductive traits from 2773 lambings of a semi-intensively managed breeding flock of Yankasa sheep at the National Animal Production Research Institute (NAPRI), Shika, situated within the subhumid zone of Nigeria. Edited records of 2204, 2490, 1225, 1461, 1196, 1204 and 247 l... Continue Reading
Crop environment and weed interaction were assessed in miliet/cowpea and millet/cowpea/sorghum cropping systems under traditional and improved agronomic conditions in Che Sudan Savanna zone of Nigeria. The specific objectives of the experiment were to measure the effect of the intercropping on light transmission, assess the effect of intercropping ... Continue Reading
Two experiments were carried out with male and female (non-pregnant and non-lac tating) Yankasa sheep to determine the nutritive value of wheat offal. The two experiments were growth experiments and lasted for 56 and 70 days respectively. The treatments consisted of the following wheat offals levels, 0, 30, 60 and 90%. The results indicated that up... Continue Reading
A total of 479 calves in 27 herds were examined for diarrhoea and enteric pathogens. The overall prevalence of diarrhoea was 13.6%. The characteristics of diarrhoea faeces viz, the consistency, colour and smell were evaluated and related to the causative agents. A loose greenish nonsmelly diarrhoea was suggestive of helminthic infections while whit... Continue Reading
24 weaned Yankasa lambs (12 males and 12 females) aped between 6 and 9 months and weighing between 10.3 kg and 27. 8 kg were used for the experiment. The animals balanced for weight were randomly alloted to four treatments with each treatment consisting 3 ram - and 3 ewe - lambs. The four treatments were designated High-high (HH), High-low (HL), Lo... Continue Reading
A study involving three feeding trials was conducted in an attempt to design a hot season feeding proframme for laying birds in the tropics. The first trial involved 162 29-week old hens in a 3 x 3 factorial design made up of cross-classified combinations of three dietary protein (18, 16 and 14% CP) and three energy levels (2800, 2600 and 2400kcals...

Nine feeding experiments and one metabolism study were conducted to investigate the water requirements and metabolism of some indigenous Nigerian sheep and goats including the various factors that influence it in the Sudan Savanna Zone. The studies conducted examined the wrter balance, seasonal variations, breed effect, diet effect, influence of fe... Continue Reading
The Study herein reported involves the evaluation of the dairy potential of Bunaji, Bokoloji (Sokoto Gudali) breeds on dairy productive traits in which a total of 3105 records of 761 cows over a period of 24 years were used. The records on birth weight were 3647 for the two breeds. The investigation also included the study on the environmental fact... Continue Reading
The study was undertaken with the main objective of evaluating the analysis of socioeconomic characteristics of poultry(layer) production in two local government areas of Kaduna state. The study examined the socio-economic characteristics of poultry (layer) farmers as it relates to egg production. Structured questionaire were administered to the fa... Continue Reading
The present status of fish culture development in the ten northern states were investigated. All the relevant data on one fish culture projects in the ten states were collected by visitation and the use of questionaires, it was found that a few states, notably Bauchi and Gongola are as at now, still trying to construct their first fish farms. it wa...

The study examined the effects of feeding level and rearing method on sexual development in Yankasa sheep. Seventy-two animals with mean age and body weight of 145.3 +17.7 days and 10.1+2.6 kg respectively were used for the 4 months investigation. Animals were randomised in a 3x3 factorial design with feeding rate at 3 levels (low, medium and high)... Continue Reading
