Brucellosis is one of the most notorious and widespread zoonosis caused by Brucella abortus. It is of serious economic implications to the cattle industry and thus enormous financial losses to most countries. This study focused on it serological prevalence at the Nkwen main abattoir of Bamenda (Northwest region, Cameroon) from June to September 2013. Blood samples were collected from 198 cattle and the sera were screened using the competitive enzyme linked immuno sorbent assay (C-ELISA). Results showed a seroprevalence of 4.04% in the cattle population screened. A percentage of 4.40% of the 111 bulls and 3.45% of the 87 cows were recorded as infected. There was no evidence (P>0.05) of differences in sex on the seroprevalence of brucellosis in cattle. There was no association between brucella infection and age (P>0.05). About three percent of cattle were positive for those within (<5) age group with 5(4.67%) for those above 5 years of age. The two breeds commonly consumed in the area the Red and White Fulanie with the Red Fulani having a higher infection than the White Fulani (P<0.05). The study also showed that Brucella infection was dependent on location as 5 out of the 15 villages accounting for 100% infection namely: Fundong (37.5%), Wum (25%), Nso (Jakiri) (12.5%), Metah (12.5%) and Fonta (12.5%). From these results it was concluded that brucellosis is present in the population of cattle screened. There is therefore the need for good control measures and sanitary conditions to limit the spread of the disease.

The aim of this research was to evaluate the appropriate hydro-priming interval on germination, growth and yield of kidney beans (Phaseolus vulgaris L.). The experiment was conducted in a Completely Randomized Block Design, with five treatments, replicated thrice. This study was conducted at the agricultural research farm of Pan African Institute for Development – West Africa (PAID-WA), Buea from August to October 2017. The Five treatments were: T1 (Unprimed or control), T2 (Hydro-primed for 6 hours), T3 (Hydro-primed for 12 hours), T4 (Hydro-primed for 18 hours), and T5 (Hydro-primed for 24 hours). Data were collected on percentage germination, plant height, stem diameter, number of leaves per plant, number of pods, pod weight and grain yield. The result revealed there was a significant increase in days (P < 0.05) in the germination percentage of some primed seeds and unprimed seeds across the treatment. There was not any significant difference (P > 0.05) in plant height, number of leaves, plant girth from T1 to T5. There was a significant difference (P < 0.05) in the number of pots among the primed treatments. Yield of beans also showed a significant difference (P < 0.05) with unprimed and primed plants. Seeds of T2, T3, T4, T5 produced the following yields 11.1 kg/ha, 22.3 kg/ha, 172.3 kg/ha, 277.8 kg/ha more than unprimed seeds (control) respectively. This study showed that hydro primed seeds for 6 hours produced the best growth and development aspect as well as the yield, despite the low germination percentage as compared to the unprimed and the other primed seeds.

This study evaluated the response of the giant African land Archatinaarchatina snails to three different diets, with regards feed intake, feed conversion, shell length and weight gain. A comparative cost analysis of growing snails with the different diets was also carried out. 180 snails were divided into three treatments and replicated thrice with 20 snails per replicate. Treatment I consisted of natural feed items only, Treatment II of compounded feed, while Treatment III was a mix of natural and compounded feeds. Each replicate was given 100g of feed every two days and water was given ad libitum. Feed leftovers and shell length were regularly measured and analyzed using descriptive and inferential statistics. Results showed that Treatment III snails had significantly (P<0.05) higher levels of feed intake than the replicates of Treatment I and Treatment II while no statistically significant difference (p>0.05) in feed conversion, weight gain and shell length were observed for the three different treatments. Though more expensive for poor farmers, Treatment III was found to have the best potentials for sustainability and economy of snail farming.
