    Genetic diversity of Nigerian Indigenous Sheep breeds at the β­Lactoglobulin gene locus .
    (Genetics and Biodiversity Journal, 2020-06-10) Abubakar, G. R.; Ezewudo, E. A.; Egena, S. S. A.; Usman, Abdulkadir
    The study assessed genetic diversity of four Nigerian sheep populations namely; Balami, Yankasa, Ouda and West African Dwarf (WAD) making use of blood sample. Extracted DNAs were used to study polymorphism at the β-lactoglobulin gene locus using RLFP-PCR process. Results revealed the percentage polymorphic locus was 100% while Shannon’s information index, observed homozygosity, expected heterozygosity, unbiased expected heterozygosity and fixation index were 0.656, 0.516, 0.464, 0.477 and -0.075, respectively. The gene flow (Nm) for all the population was estimated to be 7.65. The pairwise Fst was low and within the range of 0.0004(between Balami and WAD) to 0.0520 (between Balami and Yankasa). Variation within and between the populations of sheep shows that a large proportion of the observed variance (98% at p < 0.01) occurred within the breeds while only 2 % of the variance (p < 0.01) was contributed due to differences among the breeds. The nearest genetic distance was between the Balami and WAD (0.001) and between Ouda and the WAD (0.001). Phylogenetic analysis revealed three clusters. The present study showed that effort should be made to prevent the wearing away of the genetic make-up of the sheep populations considering the negative fixation index.

    INFLUENCE OF WATTLE ON UDDER MEASUREMENTS AND MILK SAMPLES OF RED SOKOTO (MARADI) DOES RAISED SEMIINTENSIVELY IN MINNA, NIGER STATE, NIGERIA
    (Journal of Arid Agriculture, 2025) Kolo, P. S.; Alemede, I. C.; Egena, S. S. A.; Adama, J. Y.; Dikko, A. H.; Abubakar, M. B.
    A two-year study on the Influence of wattle in Red Sokoto (Maradi) goats on udder measurements, milk quantity and quality was carried out at the Teaching and Research Farm of the Department of Animal Production, Federal University of Technology, Minna. Thirty-six (36) Red Sokoto goats comprising of thirty-two (32) does and four (4) bucks managed semi-intensively were used for the study. Parameters observed included udder circumference, distance between teats, change in udder circumference, change in distance between teats, teat length after milking, milk quantity and quality analysis. Data collected were analyzed using SAS statistical package. After the experiment, it was observed that Crosses between the wattle and the non-wattled had the highest (p<0.05) in terms of udder circumference before and after milking, quantity of milk and average daily milking. Wattled does in (T3 and T4) produced the highest (p<0.05) peak yield. Wattled does mated with watted bucks (T4) had the highest (p<0.05) total milk yield. Non-wattled does mated with non-wattled bucks (T1) and wattled does mated with wattled bucks (T4) had the highest (p<0.05) moisture content in the milk sample which reduced the availability of most minerals in the milk. In conclusion, attention should be focused on the crosses between the wattled and the nonwattled Red Sokoto as it gave best result in most parameters examined. Deliberate effort must be made to preserve the wattle gene to prevent the goats carrying the gene from going to extinction

    Wattle gene and its influence on reproductive performance and rectal temperature in Red Sokoto (Maradi) does raised semi-intensively in Minna, Niger State, Nigeria.
    (Lapai Journal of Science and Technology,, 2023) Kolo, P. S.; Alemede, I. C.; Egena, S. S. A.; Adama, J. Y.; Omalu, I. C. J.; Abubakar, M. B.; Agboba, K.; Maidariya, H, A; Omolade, C.; Okike, C.,; Idajili, G.; Yusuf, A.; Apata, A. M
    A study on the Influence of wattle gene in Red Sokoto (Maradi) goats on reproductive performance and rectal temperature was carried out at the Teaching and Research Farm of the Department of Animal Production, Federal University of Technology, Minna. Thirty-six (36) Red Sokoto goats comprising of thirty-two (32) does (ages between seven to eight months) and four (4) bucks (between one and half to two years of age) managed semi-intensively were used for the study. Parameters examined includes: Conception rate, Abortion Rate, Parturition, Gestation gain, Gestation length, Weight of does pre and post-partum kidding loss, Litter size, Body weight of kid(s) at birth, Mortality rate, Rate of twin/singles and Ratio of males to females, The rectal temperature, Progesterone and oestrogen profile of the does. The experiment revealed that: wattle gene had significant (p<0.05) influence on the reproductive performance of Red Sokoto does. Wattled does mated with wattled buck (T4) had the lowest weight of doe pre and post-partum. Wattled does mated with non-wattled buck (T3) and wattled does mated with wattled buck (T4) had the highest kidding loss and larger litter size. Nonwattled does mated with wattled buck (T2) and wattled does mated with non-wattled buck (T3) had the better birth weight of kids. Females mated with non wattled buck (T1) and (T3) had the highest conception rate of up to 62.5 %. Mating between the wattled and non-wattled (T2 and T3) had 0 % abortion. Mating between wattled does mated with wattled bucks (T4) had up to 50 % twins. Mating between non-wattled does mated with wattled bucks (T2) produced the highest number of males while mating between wattled does and wattled buck (T4) had the largest percentage of female kids (66.7 %).

    Effect of sex, wattle, beard, hair type, and extra teat on growth-related traits of extensively managed goat (Capra aegagrus) population of Niger State, Nigeria.
    (Equity Journal of Science and Technology, 2016) Kolo, P. S.; Egena, S. S. A.; Tsado, D. N.; Adisa-Shehu, M
    Astudy that evaluated the effect of sex, wattle, beard, hair type and extra teat on growth traits of goats extensively managed in the three Senatorial zones ( i.e zones A, B and C) of Niger state was carried out. The growth traits evaluated include body weight, body length, height-at-withers, chest depth, chest girth, head length, head width, rump length, rump width, shin circumference, fore leg length and hind leg length.Male goats had better (p<0.05) measurement in all parameters considered in zone B of the state while the females were better (p<0.05) in all parameters measured in zones A and C except for shin circumference in which the males were better in zone A. Goats without wattle showed superiority (p<0.05) in most of the parameters measured in zone C. This was not so for goats in zones A and B as there was no clear demarcation between goats with or without wattle. Goats with beard were superior (p<0.05) in most of the parameters measured in zones B and C. Coarse hair type had significant (p<0.05) effect on body weight and all the other body measurements except for height-at-withers which was not significantly (p>0.05)affected. Soft hair had significant (p<0.05) effect on body weight, and all the body measurements except for hind leg length which showed no significant (p>0.05) difference. Extra teat had no significant (p>0.05) effect on body weight, body length height-at-withers, chest depth, chest girth, head length, rump width, shin circumference and hind leg length but significantly (p<0.05) influenced head width, rump length and fore leg length. Absence of extra teat had significant (p<0.05) effect on all the parameters measured except for head length which showed no significant (p>0.05) difference. At the end of the study, it was observed that sex and major genes had significant effect on most of the parameters measured. It is recommended based on the result emanating from the study that farmers be encouraged to rear goats with beard, those without extra teat and wattle since they were better in most of the parameters measured.

    A study on the Influence of wattle in Red Sokoto (Maradi) goats on udder measurements, colostrum/milk quantity and quality was carried out at the Teaching and Research Farm of the Department of Animal Production, Federal University of Technology, Minna. Thirty-six (36) Red Sokoto goats comprising of thirty-two (32) does and four (4) bucks, managed semi-intensively, were used for the study. Parameters observed included udder circumference, distance between teats, change in udder circumference, change in distance between teats, teat length after milking, milk quantity and quality analysis. After the experiment, it was observed that crosses between the wattle and the nonwattled had the highest (p<0.05) udder circumference before and after milking, quantity of milk and average daily milking. Wattled does crossed with non-wattled bucks in T3 and Wattled does crossed with wattled bucks in T4) produced the highest (p<0.05) peak yield. Wattled does mated with wattled bucks (T4) had the highest (p<0.05) total milk yield. Wattled does mated with wattled bucks (T4) had the (p<0.05) highest moisture content in colostrum sample which reduced the availability of other minerals. Non-wattled does mated with non-wattled bucks (T1) and wattled does mated with wattled bucks (T4) had the highest (p<0.05) moisture content in the milk sample which reduced the availability of most minerals in the milk.
