Ex-situ Morphological and Morphometric Studies of the Testis In the West African Dwarf Buck GoatEx-situ Morphological and Morphometric Studies of the Testis In the West African Dwarf Buck Goat

This study was carried out to document ex-situ morphological and morphometric characteristics of the testis in the West African Dwarf (WAD) buck goat. For this aim, 24 post pubertal WAD buck testes were collected at the Ipata Abattoir in Ilorin, Kwara state, Nigeria. Gross morphologic results revealed that WAD testis was ellipsoidal in shape with 2 borders (free and attached), margins (medial and lateral) and similar surfaces (ventral and dorsal). The surfaces were covered by an outer tunica vaginalis and a deep tunica albuginea. Histomorphology showed the testis comprised mostly of rounded and some irregularly shaped seminiferous tubules (ST). Each ST was lined by a basement membrane and a layer of germinal epithelium with lumen filled with spermatozoa surrounded by an adluminal space. Gross morphometric results showed that there were no significant differences in the weight, length, width and height of the right and left testis. Also in the volumes of testes obtained by water displacement method and using the prolate ellipsoid formula. There was a strong correlation between the weights and volumes of testes obtained using these methods. There were significant differences between the volumes of testes obtained by using the prolate spheroid and Lambert formulae, when compared with those obtained by water displacement method respectively. But there was no significant difference in testicular volume obtained by the prolate ellipsoid formula and the water displacement method. Histomorphometric results revealed no significant differences in the seminiferous tubular diameter, seminiferous luminal diameter and germinal epithelia height of the right and left testes respectively. The morphological and morphometric data highlighted in this study would be useful in comparative regional anatomy and researches on the testis of these valuable breed of goats.

ABSTRACTA study was made of some aspects of reproduction in the Nungua Black Head and the Ghanian variety of the West African Dwarf sheep. The gestation period of the two breeds was similar: 150 and 148 days respectively. Ewes mated in August and September tended to have slightly longer gestation periods than those mated in March. The mean birth weights were 2·2 kg in the Nungua Black Head and 13 kg in the West African Dwarf. Type of birth affected the weight of lambs at birth. The Nungua Black Head had no triplets, 0·132 twins and 0·868 singles. The West African Dwarf was more prolific: 0·402 singles, 0·557 twins and 0·041 triplets. The weight advantage of the Nungua Black Head lambs at birth was maintained to weaning and they also had better survival rates. The adjusted 12-week weaning weights averaged 9·8 and 5·8 kg respectively for the Nungua Black Head and West African Dwarf. What the West African Dwarf lost in individual weight it appeared to make up in numbers so that, when the breeds were compared in terms of kg of lamb weaned per ewe mated, there was no significant difference between them.

The study was carried out to evaluate the significance of ultrasound in the early detection of testicular pathology in the West African Dwarf (WAD) buck; hormonal, morphological and morphometric studies were used as correlates. Twelve matured WAD bucks divided into two groups (of 6 per group); A—control, B — bucks with right testis spermatic cord ligated for four weeks were used for this study. Testicular ultrasound protocols were carried on the Longitudinal Planes (LP) and Transverse Planes (TP) on both testes. Blood samples were collected via the jugular vein twice a week for four weeks and assayed for testosterone, Luteinizing Hormone (LH) and Follicle Stimulation Hormone (FSH) concentrations. The testes were harvested after four weeks and carefully separated from the epididymides for gross and histological studies. Results revealed that 24 hours post induction of testicular pathology, inflammation of the right testes of the group B bucks was detected by ultrasound as hypo-echoic (dark) regions covering about two-third of the entire testis while the non-ligated testes appeared mostly homogeneously greyish on the TP. By the end of the fourth week the entire ligated testes were inflamed and appeared hypo-echoic with some areas of fibrosis on the TP and LP. The LH and FSH concentrations increased while there were no significant changes in testosterone concentrations. There were marked reduction in testicular and epididymal weights and sizes in group B bucks. The group B bucks testes showed complete loss of testicular architecture while the Leydig cells were intact. In conclusion, testicular ultrasound was valuable in the early detection of the induced testicular pathology (which hormonal, morphological and morphometric studies confirmed), hence should be adopted as part of the BSE programme of the WAD buck.

The study evaluated the effects of level of feed offer on dry matter intake (DMI) , digestibility, the parts of plants selected and on the growth rate of West African dwarf (WAD) goats without resulting in toxicity. Seven different levels of feed offer ranging from 40g/kg0.75/day to 130Wkg0.75/day in increments of 15g/kg0.75) were fed to two groups of goats. The first group was fed 100% Gliricidia while the while the second was fed 50% Gliricidia and 50% Leucaena diet (50/50). The level of feed offer had significant effect on the DIM and digestible DMI (DDMI) of the goat (P < 0.01). The Leucaena intake in a 50/50 diet was always higher than the Gliricidia intake except at 55g1kg0.75 offer level. The level of feed offer had significant effects on the parts of plants selected (P < 0.01.) and on the growth rate. The leaf intake was statistically higher than the stem intake (P < 0.01). All the goats on 40g/kg0.75 and 55g/kg0.75 on a 100% Gliricidia diet lost weight while only those on 40g/kg0.75 lost weight on a 50/50 diet. There was no significant difference in the growth rate of goats on feed offer levels of 70g to 130g/kg0.75 (P > 0.05). The study indicate that goats performance was higher on a mixed browse diet than on Gliricidia alone. Goats performed best at 100g/kg0.75 offer level.

This chapter discusses the evolution of punk in Russia since its inception at the end of the 1970s. It pays particular attention to the changing perception of class belonging and the political engagement of the punk scene in Russia. Whereas in the West punk was a political movement closely associated with its working-class background, in the Soviet Union it emerged as a protest of middle-class intellectuals fighting for the right to be different and to stand out from the uniformed workers’ and peasants’ collective. This defined the particular stand of early Russian punk toward the genre’s social engagement and political appeal. Working-classness and political commitment—initial conditions of punk identity in the West—became something early Russian punk was positioned against. The dramatic transformation of Russian society over the following decades inevitably affected the cultural ideology of Russian punk, and from the 1990s onward it had to find its place and defend its significant difference amid the realities of “wild” neoliberal capitalism. The chapter shows how in Russia punk evolved from being a highly individualistic and apolitical practice to one of the most radical and politically committed scenes, closely affiliated with other struggles on the Left.
