This study was conducted on cattle milk production characteristics among agro-pastoralists in North West Nigeria. The study described the socio-economic distribution of cattle milk producers and evaluated the cattle milk production techniques in the study area. A three stage (multi-stage) sampling technique involving a combination of purposeful, random and snow ball sampling were used to select 157 respondents. Data were collected from sampled population using structured questionnaire. The data obtained were analysed using descriptive statistics which include frequency counts and percentages. The study showed that most of the respondents (81.3%) were involved in rearing of cattle used for milk production as agro-pastoralists. The overall average number of cattle per herd in the study area was 17 heads of cattle. Labour for extraction of milk was majorly provided by men (80.6%) based on the overall analysis of the four States considered. Average milk per herd per day is 9 litres. Abo...

There is need for characterization of performances of cattle breeds in relation to milk yield and composition particularly in Adamawa State where seasonal fluctuations in climatic elements can affect livestock resilience. This study was carried out to evaluate the breed variation in milk yield and composition of some selected breeds of Nigerian indigenous cattle in Adamawa State in the late wet season (August-October). The milk of 20 cows each from four breeds (Bunaji, Rahaji, Adamawa Gudali and Bokoloji) was sampled for milk yield and composition analysis three times within the season. Milk was analysed for its composition. Breed significantly (p<0.05) influenced the milk component evaluated. Bunaji was superior in milk yield (1.92), fat yield (5.73) and total solid non-fat (4.59). Rahaji was superior in phosphorus (410), sodium (61.01) and iron (3.16) while Bokoloji was superior in protein (4.98) and calcium (721).

A total of 65 Yankasa, 23 Uda and 16 Balami ewes were mated to 4 Yankasa, 3 Uda and 3 Balami rams in a diallel breeding pattern to produce 192 lambs within 9 genotypes, which were used to study survivability of lambs in relation to their dam?s haemoglobin variants. Blood samples (5ml) were collected from 104 ewes and 10 rams through jugular venepuncture. Electrophoresis was carried out in a Shandon electrophoresis tank on cellulose acetate strips. Each of the 9 lamb genotypes had very high proportion of HbAB. The dam?s haemoglobin type BB (HbBB) were only found in YK X YK, UD X UD, YK X UD, BL X YK and BL X UD lambs at birth and 90-Day. Survivability of lamb that were given birth to by dams with haemoglobin type (HbAB) is highest in the studied populations from birth to 360-Day. Lambs with Hbshould be selected for improved survivability of sheep in Northern Nigeria.

This paper is focused on reviewing the three key pillars of climate-smart agriculture (CSA) in relation to livestock production (i.e., increased productivity, mitigation of greenhouse gases emissions and adaptation to climate change) while exploring the development intervention options for Nigerian livestock farmers. The most serious impacts of climate change are anticipated in grazing systems because of their dependence on climatic conditions and the natural resource base, and their limited adaptation opportunities. Impacts are expected to be most severe in arid and semi-arid grazing systems at low latitudes, where higher temperatures and lower rainfall are expected to reduce yields on range lands and increase land degradation. The dual pathways of responses between climate change and livestock production activities were depicted in this review. It is of note that climate change as a natural phenomenon works on the principle of causes and effect. The actions and in-action...

The objective of the study was to investigate the effect of storage methods on egg quality indices during the hot (March-April) season. A total of 427 eggs were used for this study. The different storage methods used were refrigeration (R), room temperature (RT), oiling (O), covering with mango leaves (CWML) and earthen pot (EP) storage. The parameters measured were Haugh unit, albumin height, yolk height and yolk width. The average temperature for the hot season was 32 0 C while the relative humidity was 36.84%. The results obtained showed that egg quality indices were significantly (P<0.05) affected by the different storage methods. The increased time of storage regardless of the temperature caused loss in internal egg quality according to the results of this study. Eggs that were stored by R, O and EP methods kept the shelf life of eggs for a longer period compared to RT and CWML storage which lost quality rapidly after extended storage. The duration at which eggs can be store...

Structured questionnaires were administered on 228 respondents within Zaria and its environs to evaluate the acceptability of chicken egg as food despite its cholesterol content. The study was conducted between May and June, 2009. The questionnaires were retrieved; collated and data analyzed using Statistical Package for Social Sciences (SPSS). The data were analyzed for frequencies and correlated relationships between the measured attributes. The results indicate equal distribution between male (49.6%) and female (50.4%) respondents. The highest percentage of the respondents was between the active age group of 20 to 50 years of age. Most of the individuals interviewed were either single (59.2%) or married (33.3%). About 70% of the respondents had tertiary education while the rest had secondary (27.2%) and primary (3.1) education. The respondents were mainly students, civil servants, academics and private business people and their corresponding respective frequencies were 98, 60, 19 and 51, respectively. Almost all (93.4%) the respondents liked chicken egg as food. 63.2% of the respondents ate an egg per meal while 7% of them did not eat egg at all. Age and profession of respondents significantly (P<0.05) affected respondents' likeness for chicken egg. This study therefore, shows that the higher the level of education the more the fear of the cholesterol in chicken eggs.

This study was aimed at evaluating the effect of season on haematological profiles of lambs in Northern Guinea Savannah Zone of Nigeria. Blood samples (5ml) were collected from 76 lambs from the mixed flock of Balami, Uda, Yankasa sheep and their crosses through the jugular vein. The data obtained were analysed using General Linear Model procedure of SAS (SAS, 2004). Season had no effect (P>0.05) on all erythrocyte indices of lambs except mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH). Early dry season recorded higher MCV and MCH value than early wet season. The values for MCV were 28.51±0.50 fl and 27.74±0.40 fl for early dry and wet season, respectively while 9.34±0.21 pg and 8.22±0.16 pg were obtained respectively for MCH during early dry and wet season. Season affected (P<0.05) all the leucocyte indices except monocytes. Early wet season recorded higher values (18.01±0.37 x10 9 /litre) for white blood cells (WBC) counts than early dry season (11.68±0....

A total of 65 Yankasa, 23 Uda and 16 Balami ewes were mated to 4 Yankasa, 3 Uda and 3 Balami rams in a diallel breeding pattern to produce 192 lambs within 9 genotypes, which were used to study survivability of lambs in relation to their dam’s haemoglobin variants. Blood samples (5ml) were collected from 104 ewes and 10 rams through jugular venepuncture. Electrophoresis was carried out in a Shandon electrophoresis tank on cellulose acetate strips.Each of the
9 lamb genotypes had very high proportion of HbAB. The dam’s haemoglobin type BB (HbBB) were only found in YK X YK, UD X UD, YK X UD, BL X YK and BL X UD lambs at birth and 90-Day. Survivability of lamb that were given birth to by dams with haemoglobin type AB (HbAB) is highest in the studied populations
from birth to 360-Day. Lambs with HbAB should be selected for improved survivability of sheep in Northern Nigeria.
