The introduction of improved forage cultivars has enhanced nutrition and performance beef cattle in stall feeding cut carry systems Vietnam other Southeast Asian countries. However, the persistence these forages can be reduced by flooding waterlogging conditions low-lying land during monsoon season. This pot study was established with 5 treatments (control, 10-day single, cycle, 20-day continuous waterlogging) for an 84-day period following establishment to evaluate tolerance 7 grass...

Abstract Improved forage management can support increased production in smallholder beef systems. Our objective was to evaluate the effects of mineral nitrogen (urea) and composted cattle manure on Brachiaria cv. Mulato II yield nutritive value south‐central coastal Vietnam. Study design a randomized complete block six farms (blocks), with treatments derived from factorial combination five rates (0, 4, 8, 12 24 Mg DM ha −1 year ) three urea 60 120 kg N ), split into yearly applications....

An experiment was conducted in Vietnam to test the hypothesis that total dry matter (DM) intake and liveweight (LW) gain would increase a curvilinear manner with increasing amounts of concentrate offered.There were five treatments: basal diet Guinea grass fed at 1 % LW rice straw ad libitum (T0), or this supplemented 0.6 (T1), 1.2 (T2), 1.8 (T3), 2.4 (T4). The comprised locally available ingredients, namely cassava chips, bran, crushed grain, fishmeal, salt, urea, mixed manually.Concentrate...

Two experiments were conducted in central Vietnam to test the hypothesis that supplementation with a concentrate, comprising rice bran (45% fresh basis), maize (49%), fish meal (3%), urea (2%) and salt (1%), up 2% of live weight (LW)/d (dry matter (DM) basis) would linearly increase digestible organic intake LW gain yellow cattle.In both experiments, there five treatments, namely basal diet grass fed at 1.25% (experiment 1, elephant grass, Pennisetum purpureum; experiment 2, native grass)...

An experiment was conducted in Vietnam to test the hypothesis that supplementation with cassava powder up 2% of live weight (LW)/d (DM basis) would linearly increase digestible organic matter intake and LW gain Laisind cattle.There were five treatments: a basal diet elephant grass fed at 1.25% rice straw ad libitum or this supplemented powder, containing urea, about 0.3, 0.7, 1.3 2.0% LW.The cattle did not consume all supplement, actual similar 1.3% treatment.Organic matter, energy intakes...

The objective of this study is to evaluate the characteristics smallholder beef cattle production in Central Vietnam. A total 360 households were interviewed by using semi-structured questionnaire; a 606 cows investigated for evaluating calving interval (CI). Thirty-two fattening monitored estimation diet structure. Results showed that herd size was 4.32-4.45 cattle/household. In North (NC), 55% surveyed farmers kept local cattle, 45% crossbreeds, and none keeping exotic breeds. South (SC),...

Increased production in smallholder beef systems requires improved forage management. Our objective was to evaluate the effects of composted cattle manure and mineral nitrogen (urea) application on soil fertility partial nutrient balances plots established Brachiaria cv. Mulato II south-central coastal Vietnam from 2010 2013. A randomized complete block design implemented six farms (blocks), with five rates (0, 4, 8, 12, 24 Mg DM/ha per yr) three urea 60, 120 kg N/ha a factorial design. Soil...

In South Central Coastal Vietnam, on-farm research and farmer experience demonstrated the benefits of growing improved forages as a means improving year-round quantity quality feed available for smallholder beef cattle production. Binh Dinh, Phu Yen Ninh Thuan provinces, 5 new forage species ( Panicum maximum cv. TD58 , Brachiaria hybrid Mulato II, Pennisetum purpureum VA06, Paspalum atratum Terenos Stylosanthes guianensis CIAT 184) were evaluated yield crude protein concentration. There was...

Abstract Cattle manure value chains play important biological and economic roles in smallholder crop–livestock systems developing countries, but relative to other livestock products our understanding of the nature impact sales is limited. In regions with an active trade, farmers face a choice between use on-farm sales, which affects nutrient flows participant incomes. We analyzed chain operating south-central Vietnam as example function role trade systems. Lowland cattle sell through network...

The objective of this study was to evaluate the predictions dry matter intake (DM) and average daily gain (ADG) Vietnamese Yellow (Vang) purebred crossbred (Vang with Red Sindhi or Brahman) bulls fed under conditions using two levels solution (1 2) large ruminant nutrition system (LRNS) model. Animal information feed chemical characterization were obtained from five studies. initial mean body weight (BW) animals 186, standard deviation ±33.2 kg. Animals ad libitum commonly available...

Three experiments were conducted in Vietnam to measure responses forage intake and diet digestibility concentrate feeding growing cattle. The basal all was grass (elephant grass, Pennisetum purpureum, 1 2; native experiment 3) fed at 1.25% liveweight (DM basis) during the day rice straw ad libitum night. cassava powder plus urea. In 2 3, a formulated comprised of maize, bran, fish meal, urea salt used. concentrates offered ~0.3, 0.7, 1.3 2.0% each experiment, zero treatment also included....

We investigated the impact of growing introduced forages on cattle production in three communes (Cat Trinh, An Chan and Phuoc Dinh) South Central Coastal Vietnam. New forages, management, feeding practices were to 45 selected Best Bet Farmers (BBF) using participatory-adaptive methods over a 3-year period. The BBF changed their system from grazing harvesting native partial plus stall-feeding cultivated forages. This reduced labour time for because they spent less managing cutting forage...

Twenty-five Bach Thao bucks (7 months old and 20.9±0.3 kg BW) were used to quantify the effect of concentrate supplementation on growth performance, rumen volatile fatty acid profile, digestibility plasma metabolites. Goats allocated into five treatment groups varying levels supplementation: Control (ad libitum access elephant grass), 0.6% C (control plus concentrates), 1.2% Concentrates), 1.8% Concentrates) 2.4% as a percentage liveweight dry matter basis. Growth feed intake measured in 6...

An experiment was conducted to determine effects of forage sources in fermented total mixed rations (FTMR) on feed intake, nutrient digestibility, rumen characteristics and ruminating behaviours local growing yellow cattle.Four male cattle with 12 months age, initial live weight 136.1 ± 9.44 kg (mean standard deviation) were used a 4x4 Latin square design experiment.Treatments namely corn foliage (FTMR1), cassava (FTMR2), sugarcane leafy tops (FTMR3) elephant grass (FTMR4).Forage accounted...

The experiment was conducted in A Luoi district, Thua Thien Hue province of Vietnam, to evaluate the effect concentrate supplementation on reproductive traits local Co goats and growth performance their kids. total 20 pregnant last 1.5 month pregnancy were monitored two cycles. Goats randomly divided into dietary treatments as control (CG), which animals freely grazed, (EG), concentrates supplemented at 1.0% 1.5% BW late gestation lactation periods, respectively. After kidding, kids each...

This study assessed the goat-fattening system among households, its economic efficiency, and farmers` constraints in goat fattening. A survey was conducted with 30 farmers randomly selected Nghe An province. The results showed that goats are kept confined fed a high level of commercial concentre (46-60%) diet. Two types have been used for fattening: growing culled female two breeds (Co breed/Lao Boer crossbred). average fattening farm size 88.2 goats/period. weight fattened selling from 29.0...
