Collaboration for Agriculture and Rural Development (CARD) Program 208 AGRICULTURAL EXTENSION AND TRAINING FOR BEEF CATTLE DEVELOPMENT IN NGHIA DAN, NGHE AN Project title: Nghe An Province Sustainable Village Based Beef Cattle Development Training and Extension Program Code of the project: CARD 010/06 VIE Author(s): Hoang Van Tao1, Nguyen Quoc Toan2, and Timothy Graham Harvey3 Project Implementing organisations: 1 Nghe An 19th May Fruit and Vegetable Company; 2 Bavi Cattle and Forage Research Centre under National Institute of Animal Science; 3 Massey University, New Zealand. SUMMARY The Beef Cattle Development Plan for 2010 (No1155/QD-UB Nghe An) was introduced in May 2003. The plan set objectives to increase beef production, use crossbreeding to introduce new breeds and improve rural incomes. The traditional VN beef industry is based on very small household farmlets, grazing waste land; this model has proved unsustainable. This project is developing a sustainable, economic village based beef farming model to improve long-term meat supply, and improve incomes. This project is implementing and evaluating the village based beef farming system in the Nghe An Region and three rural villages, which have below average household income levels (Nghia Lam, Nghia Son and Nghia Yen). The project has introduced new tropical pasture species from Thailand that are proving very effective in improving nutrient levels and increasing protein availability. The introduction of bi-product silage to the nutrient mix is also proving very effective, especially the introduction of cassava leaf silage. The beef cattle genetic base in the region is very low and the project has introduced Sindi, Brahman and Droughtmaster to improve long-term potential Key words: beef production, small householders, project, pastures, silage, extension, training 1. Background Nghe An is the biggest province in Vietnam with the area of 15000 km2 and the population of more than 3.4 million persons, of which 70% is farmers living in rural regions that have lower living standards and social-economic conditions than the average level in the whole country1. In the province, the traditional agriculture mainly relies on horticulture, animal husbandry only occupies a small part in the whole agricultural income1. The livestock production sector has had little investment over the last 20 years. Therefore the structure of livestock production systems is poorly established, with old technologies used. In order to change the agricultural structure reasonably, increase livestock production, diversify agricultural products and achieve sustainable rural development, the national and provincial governments have issued the policy of strengthening and pushing the livestock production including beef cattle development on the aspect of increasing the productivity and quality of the products in animal husbandry. CARD 010/06 VIE – Beef cattle development in Nghe An 209 Some new beef breeds have been introduced in the province through artificial insemination technology and direct importation. However, the provincial beef development has still been slow because of farmers' low knowledge in animal nutrition balance and limited application of new technologies, especially in remote areas. All of this is shown by the small population of beef herds, low productivity and fertility and limited growth rate in the region2. Currently, the province owns about 400.000 local yellow and improved beef cattle (mainly Zebu crossed breeding), being reared separately in small sized farms from lowland to plant for the purposes of food and/or draught3. These animals can be selected for the breeding improvement program in order to increase the effectiveness, productivity and quality. The Beef Cattle Development Plan for 2010 (No1155/QD-UB Nghe An) was introduced in May 2003. The plan set objectives to increase beef production, use crossbreeding to introduce new breeds and improve rural incomes. The project VIE 010/06 is completely suitable for the above mentioned decision No 1155. The project aims to gain the objective of developing a village based beef production at small holders in effective and sustainable model to improve beef livestock system and increase farmers' income through training and extension approaches. This project is implementing and evaluating the village based beef farming system in the Nghe An Region and three rural villages, which have below average household income levels (Nghia Lam, Nghia Son and Nghia Yen). 2. Research methodology The research project has been implemented by using agricultural extension method through training courses that were organized for the local farmers in the project site and in some locations that had an experienced time of raising cattle such as Bavi and Thaihoa. These training courses were held with different methods that were suitable for a number of selected activities and objectives. Of which, main activities were focused on beef production technologies, breeding improvement techniques, the introduction of high yield and quality species of tropical grass, animal feed preservation and processing technologies, especially the silage making technologies using different forages and by- products. To assess livestock performance by farmers themselves is the second method that the project applied during the implementation time of VIE 010/06. The project farmers were given girth tapes with using instructions to measure their animal's chest circumference besides, they were also taught how to record and assess their animal's performance every month. This method helped farmers to form the habits of observing the growth rate of their beef cattle therefore, to change appropriately the diet and ratios for their animals and compare the performance between the local and cross-bred beef cattle. The collected data has been processed by using Excel software. 3. Results and discussions 3.1 Extension activities 3.1.1 Trainers of Trainers (TOT’s) The project trained three ToT’s. The key ToT has been Mr Toan; a senior member of the BCFRC with a strong academic background in his position. Mr Toan developed training material and build on his previous experience. Knowledge developed by Mr Toan has been the experience with the new pasture species as well as providing training to both farmers and technicians in beef and dairy farming and animal husbandry management. Toan has managed the delivery of the village bull project and worked closely with the project key farmers, the distribution of pasture seed to project and non-project HH, and the distribution of pasture tillers for transplanting Hoang Van Tao, Nguyen Quoc Toan & Timothy Graham Harvey 210 in two new non-project villages. He has taken responsibility in arranging farmer training at Bavi Mr Ly is the Senior Extension Officer in the Nghia Dan District. Mr Ly is based in Thai Hoa Township (20 km from project villages) and has a team of six technicians responsible for all aspects of agriculture, with 2 on animal and forage extension in the District. Ly and his team have worked mostly with non-project villages, introduced project technologies, pasture species now established on 26 farms. In 2009 they had 30 village training seminars to 1060 farmers of which 1/3 was pasture and livestock focused. Mr Hoa is a senior animal breeding technician from BCFRC that was seconded to the project for 6-months in July 2007 to Jan 2008 provide training in animal breeding, AI and forage management. He was effective during his 6 months assignment of living and working in the village. Table 1 provides a summary of the number of farmers receiving and adopting technology from ToT’s. Table 1.

This practical training involved members of the project team, using the key project farmers farms as demonstration sites where technicians undertook practical tasks such as LWT recording, silage making and pasture establishment. Over the first 2-years of the project 20 demonstration training events were undertaken. The accumulated number of farmers attending was 131, technicians 72 and 152 hours of training was given. The events are listed in Table 2. The list does not include normal farm visits where informal training and discussion is undertaken. Approximately 50 informal visits have been undertaken in a wide range of locations, which includes the 3 project villages as well as farmers in Nghia Dan and Bavi areas.

These workshops were normally held in a classroom environment and had duration of approximately 4-hours. The project team presented technical data as well as undertaking some training on trainer methodology, adult learning and systems management. The programme normally involved both technicians and farmers and in year 2 the use of key project farmers as trainers of farmers was encouraged and developed as a concept. Over the first 2-years of the project 14 workshop training events were undertaken. The accumulated number of farmers attending was 203, technicians 119, and 62 hours of training was given.

Three specialised workshops were undertaken by BCFRC at Bavi with project farmers and technicians travelling from Nghia Dan to Bavi. The workshops were delivered in Vietnamese by experience Bavi staff. These workshops were normally of 3-days duration. The format involved classroom training as well as more practical farm visits and discussion with farmers. International training involved a 5-day filed trip to Thailand to look at new pasture species and beef production systems. This training was most successful and has led to extension and use of new tropical pasture species4. These new species have proved very successful and Dr Michael Hare, who led the trainings in Thailand, has now established an agency in Vietnam for the formal importation and distribution of pasture seeds. Over the first 2-years of the project 4 workshop training events were undertaken. The accumulated number of farmers attending was 31, technicians 20, and 307 hours of training was given. The events are listed in Table 4. One formal training event in New Zealand was undertaken in 2007. This training involved the 2 project leaders Mr Diep and Mr Toan and included training in beef production systems, beef marketing, conservation of forage and training methodologies. A second training event for 2 people was held in Queensland, Australia in Feb 2010. One Massey University CARD 010/06 VIE – Beef cattle development in Nghe An 213 scholarship was completed at the beginning of the project with Mr Toan spending 2-months in New Zealand undertaking practical and formal training in NZ farming systems.

Key project activities such as: using project Sindi bulls to crossbreed local cows, with identification of improved bulls to successfully crossbreed/mate; establishment and harvesting of new pasture species/varieties; application of silage technology; providing small scale equipment such as small grass choppers, silage tanks, new pasture varieties, ear tags, and a measuring tape to reasonably accurately estimate cow liveweight on a regular basis. 3.2.1 Improvement of local cows The project has introduced Red Sindhi bulls as Stage I. Once Red Sindhi crossbred female replacements are mature, there will be the opportunity to introduce a third breed i.e. Droughtmaster and Red Angus. A small three year project can only just start a genetic improvement programme and will require on- going support to be effective. Caption Village Bull 3.2.2 Establishment of new pasture species/varieties and application of silage technology Collaboration for Agriculture and Rural Development (CARD) Program 214 In 2007 the project identified the following new pasture options which were evaluated with project and non-project farmers: * Mulato II (Brachiaria ruziziensis x Brachiaria brizantha x Brachiaria decumbens) Mulato II is an improved bred hybrid cultivar bred at CIAT in Colombia and released in 2004 for more fertile soils that soybeans will grow in. Mulato II is a high quality forage grass. The grass has a hairy stem which can irritate the arms of some peoples when being hand harvested. Mulato II pasture * Ubon paspalum (Paspalum atratum) is a wild species native to central-western Brazil and adapted to low pH soils and tolerates Al toxicity. Ubon paspalum has very wide leaves and a very high leaf/stem ratio. Farmers find it very easy to cut because it is so leafy. Ubon paspalum is a very palatable grass, has good digestibility but its crude protein levels are lower than other grasses (5-10%). Cutting Ubon paspalum * Improved Napier grass species. There are two improved Napier grass species that are far leafier than the common Napier grass planted by farmers in Nghia Dan district. Cultivar Mott is called dwarf Napier and is more leafy and suitable for grazing than common Napier grass. Hybrid Napier or banana grass (Pennisetum purpureum x P. americanum) is a cross between Napier grass and pearl millet. Improved Napier grass in Thai Hoa Application silage technology The project has introduced silage technologies to the farmers. The uptake of this technology has been varied; however, the best farmers have seen tremendous benefits. The best combinations of silage are:  Napier grass 70% cassava leaf 30%  green maize stove 60% cassava leaf and top 40%  sugar cane top 70% cassava leaf and top 30%  Napier grass with additives All four options increase nutrient levels of conserved feed well above any traditional methods. These conservation options also reduce fibre and increase intake. The cost of these options is all low (i.e. 500-600 dong/kg DM). CARD 010/06 VIE – Beef cattle development in Nghe An 215 Training Outcome: Farmer attitudes to change and acceptance of new technologies was variable with a small proportion of farmers not prepared to adopt or change their approach. The reasons for this varied from lack of motivation due to age, enjoyment of the lifestyle of communal grazing of cattle, lack of labour or capital to implement change, lack of education to understand the concepts. The number of farmers in this category ranged from 10-25% of groups evaluated. This level is not surprising given the rural nature of the project site. The majority of farmers accepted the new technology in some form with some making radical changes, others just changing minor aspects such as nutrition balancing. The three most successful technologies introduced through training was: 1. the introduction of new tropical species of pasture, 2. nutrient balancing (especially reduction in fibre intake) and 3. the use of new improved genetic bulls. Where farmers could get direct access to these tec
