Indigenous pig management practices in rural villages of Western Kenya
2011
Mutua, Florence K. | Dewey, Catherine 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.

2012
Mburu, S. | Njuki, Jemimah | Kariuki, Juliet B.
Access to timely and reliable information on livestock production and marketing is important in addressing the production and marketing aspects of the sector alongside access to financial services. This study analyzes the intra-household disparities in access to information and financial services among rural households in selected districts in Kenya. Specifically, the study compares women’s access to information on livestock production and financial services with that of men. Results show that informal channels such as farmer to farmer interactions were the key sources of information for livestock production and marketing. More men in male headed households received more training and were exposed to greater and varied topics than women. Men borrowed more from formal credit providers such as banks and co-operatives while women mainly borrowed from their community groups and neighbors. Analysis of determinants of savings by women revealed that women’s age and education positively and significantly increase their probability to save.

2010
Moges, F. | Dessie, Tadelle
A study was conducted to assess the existing village chicken and egg marketing system of Bure district, North West Ethiopia. A participatory rural appraisal and a formal survey were used to collect all the relevant data, using a multistage sampling technique. Seven farmer kebeles (2 from high land, 3 from mid altitude and 2 from low land agro ecologies) and a total of 280 village chicken owner households were selected and considered for the study. In addition, 30 chicken and egg collectors (middle men) were interviewed using a structured questionnaire. All local and urban markets were visited once in a month in all seasons of the year. The result of the current study revealed that there was no any formal chicken and egg marketing operation in the study district. The result showed that 69.3% and 99.6% of interviewed village chicken owners involved in marketing of chicken and eggs, respectively. Producer-Consumer, Producer-Middle men, Producer-Retailer, Middle men- Retailer, Middle men-Consumer were the prevailing chicken and egg marketing channels of the study district. According to the result of the study village chicken owners traveled, on average, a distance of 5.5km and 15.9km to reach to nearby local markets and urban markets, respectively. It is identified that the majority (59.3%) of chicken owners used both hand carrying (hanging birds with a piece of stick) and carrying birds with bamboo-made containers to transport live birds to markets. The result of the current study revealed that the price of chicken and eggs showed variation between months of the year. The percentage increase in market prices of chicken products at holyday market days, as compared to ordinary market days was 19.2% for cocks, 15.3% hen, 24.2% for pullets/cockerels and 16% for eggs. Some of the major marketing problems identified in this study were: low supply of marketable chicken products, presence of only few/limited market out-lets and lack of appropriate marketing information. It is suggested that chicken and egg marketing of village chicken producers can be improved through development of market information system at farmer’s level and strengthening of agricultural extension services, through trainings and advisory services.

2012
Heinritz, S.N. | Hoedtke, Sandra | Martens, S. | Peters, Michael | Zeyner, Annette
Herbage of Cratylia argentea, Desmodium velutinum, Fleminigia macrophylla, Leucaena diversifolia, Canavalia brasiliensis, Centrosema brasilianum, Clitoria ternatea, Lablab purpureus, Stylosanthes guianensis and Vigna unguiculata from the CIAT (International Center for Tropical Agriculture) gene bank were assessed for their nutritional value and in-vitro digestibility for pigs in order to predict their potential as alternative protein supplement in a tropical smallholder context. Crude protein (CP) contents ranged from 137 to 257 g kg-1 dry matter (DM) (mean 191 g kg-1 DM), although a considerable proportion of it, 27 % on average, was bound to neutral detergent fiber (NDF). Interesting levels of lysine were found in Cratylia argentea (14 g kg-1 DM) and Leucaena diversifolia (13 g kg-1 DM), whereby the latter was also high in tannic acid concentration (49 g kg-1 DM) thus limiting the amino acid digestibility. Vigna unguiculatapresented highest in-vitro enzymatic degradability (521 g kg-1 DM), which even increased in a 40:60 mixture with maize. Lowest degradation was obtained with Flemingia macrophylla (248 g kg-1 DM), while the median of the forages approached 390 g kg-1 DM. It is concluded, that Vigna unguiculata herbage meal has the highest potential to be successfully included in pig diets, while Cratylia argentea meal should equally be assessed in vivo.

2003
Javed, K. | Farooq, M. | Mian, M.A. | Durrani, F.R. | Mussawar, S.
A study was conducted during the year 2000 to investigate flock size and egg production performance of backyard chicken maintained by woman in rural areas of Peshawar, NWFP, Pakistan. One hundred and thirty female farmers were selected at random from 13 randomly selected nearby villages of Peshawar city. Average flock size maintained by a household in rural areas of Peshawar was 26.1 ± 0.69 chicken with a higher number of adult birds (14.5 ± 0.50) than chicks (11.6 ± 0.41). Fewer chickens was found in flocks given no housing facility (24.3 ± 1.02 ) than those given part time housing facility (29.4 ± 0.85). Higher number of chickens/household was found with flock owners vaccinating their chicken against ND+Fowl-pox than those not vaccinating their chicken against these diseases. On the average 2315 ± 66.2 eggs were obtained by a household. Egg production/bird irrespective of the breed was found to be 142 ± 3.17 eggs. Of the total eggs produced, 703 ± 3.8 eggs were consumed by the household on annual basis. More eggs per bird were produced by Rhode Island Red (RIR) than Desi chicken. Flocks given a part time housing facility produced more eggs/bird than those given no housing. Flocks reared in normal human dwellings also produced higher number of eggs per bird than those given no housing. More eggs/bird were obtained from flocks vaccinated against ND+fowl-pox disease than non-vaccinated flocks. RIR produced higher number of eggs/bird under scavenging conditions than desi, Fayumi and White Leghorn chickens. Effective health coverage, housing facilities and rearing of highly productive chicken will improve backyard chicken production in rural areas of Peshawar.

Reproductive performance of traditionally managed sheep in the south western part of Ethiopia
2009
Berhanu, Belay | Haile, Aynalem
The study was conducted to assess the reproductive performance of ewes under village management condition in south western part of Ethiopia. The study was a monitoring study which took place for three years (1995-1997). The overall least squares means for lambing interval (LI) and annual reproductive rate (ARR) were 262 ±53.4 days and 1.88 ± 0.44, respectively. The overall least squares means of age at first lambing and litter size were 404 + 65.40 day and 1.21+1.45 lambs, respectively. Lambing interval was significantly (P<0.05) influenced by parity of the ewe, type of birth and year of lambing. The ewes at their first, and six and above parity showed longer subsequent lambing interval than ewes at 2-5 parity. Ewes that suckled singles had shorter subsequent lambing interval than ewes which suckled twins (255+3.74 vs 283+5.72 days). Year of lambing and type of birth exerted a significant effect (P<0.05) on ARR. The ewes that dropped twins had higher ARR than ewes which dropped singles (1.52 Vs 2.56 lambs/ewe/year). Litter size was significantly (p<0.05) influenced by season of lambing and parity of the ewe. There was a tendency that, litter size increased with an increase of parity up to fifth parity and dropped at the sixth and more parities. The reproductive performance of ewes under village management condition is discussed in association with reports elsewhere in the tropics.

2012
Bett, R.C. | Okeyo Mwai, Ally | Kosgey, I.S. | Kahi, A.K. | Peters, Kurt J.
his study evaluated alternative breeding objectives and schemes for crossbred goats in a village/ community breeding program. A single-tier breeding structure was assumed in the optimisation of this breeding program. Considered were two selection schemes; within-group (WG) and across-groups (AG), and three alternative selection objectives; ALT I- defined based on relative weights (RWs) derived from producers’ preferences, ALT II- based on economic values (EVs) without risk and ALT III- based on risk-rated EVs, at different intensities of buck selection (proportion of bucks selected, P = 0.02 and 0.04) and selection criteria (mass and BLUP). The genetic gains (ΔG) in the breeding-objective traits, aggregate responses (RH), total economic response (TER) and the rate of inbreeding (ΔF) per generation varied depending on the scenarios ALT I, II and III, P and the selection criteria. A selection index considering ALT III (Risk-rated EVs) in derivation of ΔG for individual traits, RH and TER, and ΔF would be appropriate and optimal in both WG and AG selection schemes. However, these responses were higher in the AG scheme compared to the WG selection scheme, and the ΔF more favourable with increase in the number of groups co-operating. Responses under mass selection were also comparable to BLUP with the same rate of inbreeding, restricted to an acceptable level of 0.01. These imply that an AG selection scheme under mass selection would be optimal and logical for implementation in the smallholder low-input goat production systems. However, a minimum of 14 co-operating farmer groups would be required to produce considerable levels of responses and at acceptable levels of inbreeding.

Village chicken constraints and traditional management practices in Jamma District, South Wollo, Ethiopia
2011
Mengesha, M. | Tamir, B. | Dessie, Tadelle
This study was conducted in four Peasant Associations in Jamma district. A total of 120 households from four PAs were involved in the study. Ninety eight percent of farmers were supplementing extra feeds and water for their chickens, with the main proportion of food leftover (26.4%) followed by spoiled grain (25.1%). The proportions of households providing supplementary feeding were: 19.8, 21.5, 37.3 and 21.4% in the morning, at noon, afternoon and evening respectively. Most of the households (77.7%) were not giving feeds separately to the flock compositions. Households were practicing of chicken selection with the main characters of egg productivity (35.4) and body weight (38.4%). Majority of households (78%) were using their living room for birds penning at night and women were more (72%) responsible for flock management. The larger eggs with oval shape and smooth in eggshell were the preferred characters in selection of incubating eggs. Farmers (38%) adapted a practice of mixing local eggs with exotic or crossbred eggs while incubating for better hatchability of exotic or crossbred eggs. Around 73% the respondents reported that the highest mortality of chicks was occurring up to 2 weeks of age. But around 12.6% of the households were treating their sick birds with traditional-treatments. Ninety-one per cent of farmers pointed out that more frequently occurring and devastating disease was Newcastle Disease.
