Response in digestibility, growth performance, and carcass quality of local Kandol pigs to incremental levels of fermented banana stems.

Fermentation of banana stems is a novel method for increasing the digestibility of fibrous porcine rations in the tropics; however, optimal feeding rates have not been determined. An experiment was carried out to determine the response of digestibility, growth performance, and carcass quality in local Kandol pigs to incremental levels of FBS in rations. A total of 20 castrated male pigs were randomly allocated to five diets, containing 0, 400, 500, 600, and 700 g FBS of the ration. Daily feed on offer was provided as 4% of the body weight on a dry matter basis and offered three times per day. As result, the inclusion level of FBS was positively correlated with NR (p < 0.001, r = 0.68). The linear regression equation was y = 0.002x + 2.4276 (R2 = 0.63). Furthermore, it was also correlated with ADG (p < 0.05, r = 0.46) and with FCR (p < 0.05, r = - 0.45). The regression equation was y = 0.0634x + 174.2 (R2 = 0.43) and y = - 0.0009x + 4.6521 (R2 = 0.62) for ADG and FCR, respectively. The correlation between inclusion level of FBS and large intestine weight was also observed (p < 0.05, r = - 0.61). The R2 value was 63. However, there was no any correlation between the inclusion level of FBS and the percentages of hanging carcass, dressing carcass, pH, color score, marbling score of the meat, and WHC (p > 0.05). The economic benefit of using FBS to improve pig diets will depend on the availability of banana stems and the labor and processing costs.

Effectiveness and implementation challenges of a livestock asset transfer intervention for smallholders in community-protected areas in Cambodia.

BACKGROUND: Limited opportunities to generate income in community-protected areas (CPAs) often lead to the illegal harvesting of wildlife and natural resources, undermining the aim of protected areas. Sustained livestock production can be an alternative income source. OBJECTIVES: To understand the effectiveness and feasibility of livestock production in CPAs. METHODS: We conducted a livestock asset transfer intervention in 25 CPAs across three agroecological zones in Cambodia. We monitored livestock mortality, consumption and sales of livestock over 2 years. Participant observations and structured questionnaires were conducted to elicit information about constraints for livestock production perceived by the participants. A total of 756 households were recruited and 320, 184 and 252 households received chicken, pigs and cattle, respectively. All participants received technical training in livestock production and biosecurity management practices. RESULTS: After the intervention, the number of chickens, pigs and cattle increased on average by 5.9 (range: 0.3-26.3), 0.5 (-1 to 2.7) and 0.12 (0-0.35) per 1 input animal, respectively. The extent of increase was significantly different between zones only for chickens (Kruskal-Wallis test p = 0.004). The number of chickens and pigs sold per household was significantly different among zones. We observed that training was ineffective to alter livestock management practices in some CPAs, which partially explains their suboptimal performance of livestock production. CONCLUSIONS: Understanding contextual factors required for successful livestock production in CPAs is crucial for improving livelihoods and preventing biodiversity loss in Cambodia.

Understanding networks in rural Cambodian farming communities and how they influence antibiotic use: A mixed methods study.

Biosecurity and preventive animal health services in Cambodian smallholder backyard farming systems are often limited, leading to an over-reliance on antibiotics. However, data on factors influencing antibiotic use in these settings are lacking. We conducted a study in two rural Cambodian farming communities to investigate how social and contextual influences affect both human and animal antibiotic use behaviours. Data were collected in three phases: a baseline household census to enumerate village residents, a social network survey to understand village-level social ties, and in-depth interviews to elicit information about the influence of social ties on their decision-making processes. Primary outcome measures included knowledge, attitudes and practices surrounding antibiotic use, and awareness of issues relating to antibiotic resistance. Participants commonly accessed antibiotics or learned animal antibiotic use practices through village-level informal sources such as pharmacies or animal health workers. While most participants reported not using antibiotics for animal growth promotion or illness prevention, misconceptions surrounding both antibiotic effectiveness and resistance were common. Social networks capturing informal, work-related and health-related social ties showed that familial connections and geographic proximity were of primary importance for information sharing. Using exponential random graph models, we demonstrated that familial ties, and closer geographic and geodesic distance, were associated with similarity in overall antibiotic knowledge and attitudes. The informal private sector plays a major role in provision of antibiotics and antibiotic-related information in backyard farming communities, but such information is maintained within close social groups. This demonstrates the importance of engaging village-level informal sources in the provision of antibiotic-related information for both human and animal health, as well as in potential interventions to encourage appropriate antibiotic behaviours in lower-resourced settings.
