Improved pig production and health in western Kenya

A description of local pig feeding systems in village smallholder farms of Western Kenya

A description of local pig feeding systems in village smallholder farms of Western Kenya Mutua, F.K.; Dewey, C.; Arimi, S.; Ogara, W.; Levy, M.; Schelling, E. We used face-to-face interviews to gather data on pig feeding practices in rural Busia District, Kenya. We visited 164 pig farms three times in the course of the study period. The pigs were weighed in kilograms during the visits. Feeds offered to pigs were described during the interviews. The most frequently fed feedstuffs were; ground maize or “ugali” (88%), kitchen leftovers (83%) and dried fish locally called “omena” (78%). Farmers provided pigs with water separately from the feeds. Sweet potatoes, “ugali” and cassava were available and could serve as good sources of energy for pigs in the district. Fruits and vegetables were also available and could potentially act as good sources of vitamins. Sweet potato vines, “omena” fish and slaughter blood were available and could provide pigs with proteins. The average daily gain (ADG) for pigs ≤5 months of age, pigs of 5.1–9.9 months of age and pigs of ≥10 months old was 94.5 (±43), 127 (±49.8) and 99 (±92) g, respectively (p = 0.000). This study has outlined the different local pig feeds available in Busia district. We recommend two things: first, additional research on nutrient composition for the identified local feeds, and second, developing and validating simple local feed combinations that would achieve balanced local pig rations.

Indigenous pig management practices in rural villages of Western Kenya

Indigenous pig management practices in rural villages of Western Kenya Mutua, F.K.; Dewey, C.E.; Arimi, S.M.; Ogara, W.O.; Githigia, S.M.; Levy, M.; Schelling, E. The management of indigenous pigs in rural villages of Busia and Kakamega district, Western Kenya, is discussed. Data on husbandry practices, challenges and farmers knowledge on T. solium taeniosis / cysticercosis were gathered using questionnaires administered in face-to-face interviews. Pigs were examined for cysticercosis using the lingual palpation method. Data were managed in Stata®. Majority of the farmers were aged 30-50 years (44%), and were mostly women (69%). Years of pig keeping experience was higher in Kakamega (11.4±8.7) than it was in Busia (6.3±5.6) (P<0.05). Pork (31%) and beef (51%) were the most preferred meat types in the villages. Families owned an average of 0.94±0.81 hectares of land. The mean number of pigs owned per farm was 5.0 (±3.4), 1.8 (±1.2) and 1.5 (±0.9) for the pre-weaned, growing and adult pig categories, respectively. Constraints faced by the farmers included feeding (65%), diseases (46%), fewer breeding boars (60 %), poor profits (61%) and conflicts with neighbours (53%). Parasite control was poor. The majority of farmers (73%) had no pig house. These farmers either lacked skills to build the houses (11%; 23/209) or had no money to purchase construction materials (45%; 93/209). Tethering of pigs was frequent (>50%) during the planting (91%; 263 / 290), growing (90%; 263 / 290) and crop harvesting seasons (78%; 227 / 290). Prevalence of pig cysticercosis was 4.5%. Piglets were significantly cheaper in Busia (Ksh 509±57) than in Kakamega (Ksh 777±174) (P<0.05). Indigenous pig management in Western Kenya is reportedly poor. Improved knowledge coupled with changes in local husbandry practices would improve productivity, increase family incomes and safeguard the community from potential health risks associated with pig rearing.

Prediction of live body weight using length and girth measurements for pigs in rural Western Kenya

Prediction of live body weight using length and girth measurements for pigs in rural Western Kenya Mutua, F.K.; Dewey, C.E.; Arimi, S.M.; Schelling, E.; Ogara, W.O. Objectives: To develop and validate a pig weight-estimation method using body length and girth measurements. Methods: In a random sample of 288 smallholder pig farms in Western Kenya, pigs were weighed (kg) and their lengths and girths were measured (cm). Prediction models were generated using 75% of the data and validated using the remaining 25%. Weight was regressed on length and girth using mixed model analysis after controlling for village as a random effect. Models were developed for pigs categorized as young (? 5 months), market age (5.1 months to 9.9 months), and breeding age (? 10 months). Results: Weights (mean ± SD) of the young, market-age, and breeding-age pigs were 12 ± 6.1 kg, 30 ± 11.4 kg, and 42 ± 17.0 kg, respectively. Models for the young, market-age, and breeding-age pigs were weight = 0.18 (length) + 0.36 (girth) – 16, weight = 0.39 (length) + 0.64 (girth) – 48, and weight = 0.36 (length) + 1.02 (girth) – 74, respectively. A single prediction model for weight = 0.25 (length) + 0.56 (girth) – 32 was also developed. Weight predicted by the models was a more accurate estimate than that provided by the farmers (P < .05). Length and girth explained 88% to 91% of the total variation in weight. Implications: The weight-estimation tool will empower Kenyan farmers to have better bargaining powers when they sell their pigs and will act as an incentive to better manage their pigs through improved feeding and husbandry.

Farmer perceptions on indigenous pig farming in Kakamega District, Western Kenya.

Farmer perceptions on indigenous pig farming in Kakamega District, Western Kenya. Mutua, F.; Arimi, S.; Ogara, W.; Dewey, C.; Schelling, E. Objectives for this paper were to: study farmer beliefs and perceptions on local pig farming practices; and to explore opportunities for improved located production in selected villages of Western Kenya. The paper seeks to understand why the local pig breed still remains the predominant breed in these areas despite numerous calls to introduce better exotic breeds. Most pigs in Kenya are of exotic breeds, intensively managed on commercial farms. Focus group discussions were used to gather data. Discussions were taped, transcribed and translated from Swahili to English. Farmers use pigs to guard homes at night, pigs also act as a charm to protect families against evil spirits. Women farmers manage the family pigs, men sell the pigs. Farmers identified feeding, marketing, and breeding as the main challenges affecting the sector. The discussions identified a number of opportunities for improved production, and likely strengthened the bond between the farmers, researchers and staff. This created an outlook that can now be used in further public engagement as ongoing research studies on appropriate feed, health and improvement of market access are being analysed.
