  1. การจัดการทุ่งหญ้าเพื่อให้มีอาหารสัตว์เพียงพอตลอดทั้งปีการจัดการทุ่งหญ้าเพื่อให้มีอาหารสัตว์เพียงพอตลอดทั้งปี Strategies • Conservation : hay , silage • Modify the pasture environments : fertilizer, irrigation, weeding • Adjusting animal requirement : seasonal mating, sell, buy • Pasture renovation or plant more pasture • Purchase of feed : green forage, grain ect.

  2. Seasonal variation of pasture availability Flowering of P. plicatulum dry season Pasture mas s & Animal requirement feed quality J F M A M J J A S O N D

  3. ชนิดของอาหารโค กระบือ • พืชธรรมชาติ native species : weeds, roadside pasture, communial pasture • เศษเหลือจากพืชปลูก crop residues : rice straw, corn stover, peanut wine, sweet potatoes wine, soybean stem, pine apple, cassava, sugar cane shoot. • แปลงหญ้า sown pasture (improved pasture) : grasses, legumes, backyard pasture, integrated with crops • ถั่วยืนต้น fodder trees : Leucaena, Sasbania, Caliandra, Gliricidia spp.

  4. ชนิดของอาหารโค กระบือ (ต่อ) • แปลงชลปรทานเพื่อปลูกพืชอาหารสัตว์ irrigated fodder crops : corn, para, napier, guinea grass • เสบียงสำรอง preserved feed : hays, silage, bypass protein (cotton seed cake, palm kernel cake, rubber seed cake) coconut extract • อาหารข้น concentrates : grain, rice bran, TMR pellets. • เศษเหลือจากโรงงานอุตสาหกรรมอาหาร wastes from food industry : moalsses, pineapple canery

  5. Annual forage integration with main crops • Pearl miller (Pennisetum americanum) eg. Nutrifeed • Sorghum (Sorghum bicolor X S. sudanense ect.) eg. Jumbo • Corn • Sunflower

  6. Use of forage legumes and agroecosystems • Protein bank • Rotational plot and mixed pasture • Shrub legumes as fence and alley cropping • Three strata forages production systems (Indonesia) • Sylvopastoral

  7. Utilization of topography and climate more effectively • Ponded pasture : Hymenachne pseudointerupta, para grass, Humidicola grass, Sesbania spp., Aeschynomene americanum cv. Glen & cv. Lee • Drought tolurance spp. : • Acidic soil tolurance spp. : • Heavy grazing tolurance spp. :

  8. Other crop managements • grazing heavy prior drought reduce excess LAI to avoid water loss during dry season • ponded pasture : Brachiaria mutica, Hymenchne amplexicanle, H. acutiglume, H. pseudointerupta, Echinochloa polystachya, Aeschynomene americana • burning to control weeds and stimulate sprout • goats browsing to change damage site on pasture

  9. Forage quality triangle for critical pasture production Proper choice of species Right stocking rate, height defoliation, season Fertilizer management Type, rate, time CP = 13 % ME = 8 MJ/Kg 4 M resources availability Favourable agro-climatic conditions Proper grazing management right stage, right system

  10. The uses of burning • to control the old and low nutritive materials • to enhance reshoot • easier to oversown legumes & grasses seed • to control woody weed species • manage the animal’s tract • to control insect and parasite diseases • to make a fire break

  11. How is the pasture burned ? • Burning time • Burning temperature • Fuel load • pasture growth stage & season • and dead material mass

  12. Alter pasture demand by animal management • Seasonal mating • Rotational grazing • Sold and buy animal : what kind of animal to sold, sytems of the enterprise eg. concentrate feed vs. pasture feedlot

  13. Successful livestock production • Successful livestock production can not be accomplished by ignoring either plant or animal requirement. It will require several kinds of forages, sevaral pastures and a grazing plan. After Walker Steven S. 1998.
