With the changing climate, pastoral production systems are likely to experience even a higher impact on their sources of livelihoods. The objective of the study was to analyse climate trends and livestock disease occurrence in Kajiado County. The study used a cross-sectional design with primary data being collected through focus group discussions (FGD), key informant interviews (KIIs), and expert opinion interviews (EOIs), while secondary data was collected from the Kenya Meteorological Services and County Veterinary Services. A total of 10 FGDs, 25 KIIs, and 12 EOIs were conducted in selected areas within the five sub-counties of Kajiado. Quantitative data were analyzed through descriptive and inferential statistics while qualitative data was analyzed through Kruskall Wallis non-parametric method and content analysis. The findings show that there was an increase in variability in rainfall amounts and temperature between 1970 and 2015. For rainfall, the coefficient of variation rose from 21.6% (1970 to 1993) to 32.02% (1994 to 2015) while for temperature, the increment was from 2.6% (1970 to 1993) to 4.04% (1994 to 2015). There was no significant change in the average annual temperature and rainfall amounts between 1970 and 2015 (<em>P</em> &gt; 0.05). Among livestock diseases, trypanosomiasis and helminthiasis reportedly had higher occurrences according to records obtained from the Veterinary department but according to pastoralists, East coast fever, Foot and mouth disease, anthrax, black quarter, pestes des petits ruminants and contagious caprine pleuropneumonia were the diseases that were significantly affecting the livestock (<em>Z</em> &gt;1.96). In conclusion, the study showed that there was evidence of climate variability with livestock diseases impacting significantly on livestock production which is a major source of livelihoods for pastoralists.</p> Achola, Jacktone Yala Ogara, William Okello Ouma, Gilbert Ongisa Onono, Joshua Orungo Okuthe, Sam Oyieke ##submission.copyrightStatement## 2020-06-30 2020-06-30 1 15 Effect of Geographical Differences on Production Performance of Goat in Bangladesh <p>Bangladesh has a subtropical monsoon climate characterized by wide seasonal variations in rainfall, temperature and humidity which is suitable for goat rearing. The study was conducted to know the goat farm management and rearing system, feeding practices and productive performance in different geographical area of Bangladesh for the period of six months. The experiment was carried out during January to June in 2019. In this study data were collected from a total of 210 goat farmers in 28 different villages of north-western, north Bengal, south-western, and southern region of Bangladesh. It was observed that the feeding and management has great impact on goat production. Most of the farmers (80.5%) reared goats in semi-intensive system while, 12.2% farmers used free range system (extensive). The production rate and breeding performance was higher in semi-intensive system than that of extensive system. The main feeds for goats were green grass, tree leaves and main water source was pond though some farmers supplied concentrate feeds to their goats. The majority of goat farmers (83%) used village buck to bred their does and most of the farmers (89%) paid service charge to the buck keeper’s while, most of them did not keep own buck for natural service. The kidding rate was higher in northern region than that of southern region. In contrast kid mortality was higher in southern region (21%) than that of other region. The northern region was free from salinity, which was favorable for goat rearing. In this region the average number of goat (4.13 ± 0.45), doe (1.17 ± 0.26), buck (0.76 ± 0.01) and kids (2.21 ± 0.22) was higher than that of any other region. The southern region was showed low kidding rate and high kid mortality. The average number of goat (2.57 ± 0.28), doe (0.75 ± 0.11), buck (0.52 ± 0.11) and kids (1.38 ± 0.16) was lower in southern region than that of any other region. It was observed that the variation on production performance of goat in different geographical area of Bangladesh due to topography and salinity. Moreover, it was indicated that the northern region of Bangladesh has the highest performance of goat production both in intensive and semi-intensive farming.</p> J. Bari P. Biswas F.

In aquatic organisms, especially in fish and crustaceans, they are diagnosed with certain frequency. Taking into account that mycobacteria affecting fish, as well as the species causing leprosy, have less mycolic acid, the authors used the Fite-Faraco (FF) technique in this work and compared it with the classic Ziehl Neelsen (ZN) staining. In the Laboratory of Immunology and Pathology of Aquatic Organisms (LIPOA), the authors chose from their tissue archive tissue material belonging to 10 specimens of fish of different species, belonging to LIPOA, which were reported cases over a period of 15 years (from 2002 to 2017). The specimens had in common the presence of lesions classified as granulomatous inflammation, but with the ZN technique it was not possible to obtain a definitive diagnosis of mycobacteriosis. The authors observed that in tissues from fish infected with Mycobacteria, the FF technique was more useful, since the presence of bacilli can be observed, where previously the ZN technique was used and no bacilli were observed.</p> L.

The research lasted for five months starting from April to August 2014 and aiming at looking for the appropriate age of weaning rabbit kits. Live weight and solid feed intake were recorded after every seven days depending on the kindling date of each doe to determine their increase in weight. The litter size, still birth, mortality and weaning age were monitored for all the kits. The rabbits were weighed pre-kindling and on the day of kindling with their kits. The mortality rate was registered as well as the feed consumed during this period.&nbsp; Doe selection was done based on live body weight. The does were grouped into three groups: one having does with weights less than 2900g, group two having does with weight ranging between 2900g and 3200g and the last group with does with live weights above 3200g. Weaning was done in three phases 21days, 28days, and 35days, respectively. Data collected from the experiment were subjected to Analysis of Variance and Descriptive Statistics using Microsoft Excel application. The results obtained showed that there was a significant difference (P&lt;0.05) among means of average weights of animals weaned at the 21 days, 28 days and 35 days of&nbsp; age. The best survival rates of rabbit kids were obtained when the animals were weaned at 35days of age.</p> Kisito Nsokika Chilla Bongaman Felix Eboue Dieumou Dieudonne Kamdem Pone ##submission.copyrightStatement## 2020-08-08 2020-08-08 35 41
