  • Four pairs of draught oxen (two local and two Jersey crossbred) were studied when they ploughed dry land on local farms. Work done, distance traveled and body temperature of each ox were measured continuously over a 5 h working day. A different team worked each day, completing at least six days work each. Individual food intakes and digestibility of feed were measured when the animals were given rice straw and tree fodder, and housed and fed according to local husbandry practices. The Jersey crossbreds, particularly the longer legged type, had a higher rate of work than the local oxen in this study. They did significantly more work and covered a greater distance during the day. The absence of a hump in the crossbred oxen had no effect on the position of the yoke or the way the oxen pulled when ploughing. The longer legged type of Jersey crossbred tended to work more erratically than any of the other teams. A fast rate of work made the oxen more liable to heat stress. When fed according to local practices and given the same amount of feed as local oxen, Jersey crossbreds tended to do less well. During the ploughing months, the local oxen gained weight, while the crossbreds remained at the same or lost some weight. Although there were some disadvantages to keeping Jersey crossbreds for work, their favourable work output suggests that the introduction of the Jersey crossbred in the hills of Nepal is unlikely to be detrimental to the performance of the work oxen population.

  • This study explored agroforestry strategies to achieve ecological and economic effects simultaneously for Elsentasarhai region in Mongolia under desertification, based on attitude survey with a questionnaire, field survey on planting sites, and literature review. The agrosilvopastoral approach was suggested as a type of agroforestry practices which combined tree planting for combatting desertification and wind damage to crops, agricultural crop production for income improvement, and livestock raising, a major industry in the study region. Populus sibirica and Ulmus pumila native to desert regions were selected for tree planting, and Hippophae rhamnoides, potato, and fodder appropriate for the short growing season were chosen for income crop production, reflecting residents' attitudes and growth environments. As a strategy of land allocation to satisfy multiple effects of the agrosilvopastoral approach, the alley cropping technique was recommended which arranged alternately strips of trees as windbreaks and income crops in multiple rows. The study also explored desirable planting techniques to improve conditions of income crop production and tree growth against drought and strong winds in the alley cropping. Study results will be useful as fundamental information to implement sustainable agroforestry in Mongolia and other semi-arid regions where knowledge concerned is lacking.

  • An investigation was made to evaluate the native range of western India in terms of nutrient supply during different physiological stages in goats. One hundred female and 5 male Kutchi adult goats were grazed on a 35 ha plot of native range. They were maintained on sole grazing. Four experiments, one in a defined physiological stage was carried out. Stage I, when maximum number of females were bred; stage II, when bucks were used for breeding purpose; stage III, 3-months old (weaner) kids were allowed to graze on ranges and stage IV, when the goats were in early stage of lactation. During oestrous period, diet contained 15.2% crude protein (CP), 54.0% neutral detergent fibre (NDF), 31.5% acid detergent fibre (ADF) and 12.6% acid detergent lignin (ADL). Digestibility coefficient of dry matter (DM), CP, NDF and ADF was 0.586,0.531, 0.431 and 0.239, respectively. DM, digestible crude protein (DCP) and metabolizable energy (ME) intakes were $82.7,\;6.71g\;kg^{-1}\;W^{0.75}$ and $0.99MJ\;kg^{-1}\;W^{0.75}$. Diet of buck was constituted by $230g\;kg^{-1}$ DM of grasses and forb and $770g\;kg^{-1}$ DM of tree foliage. CP, NDF, ADF and ADL contents of the diet were 13.6, 57.8, 43.5 and 20.0%, respectively. DM, DCP and ME intakes were $57.9,\;4.13g\;kg^{-1}\;W^{0.75}$ and $0.82MJ\;kg^{-1}\;W^{0.75}$. Digestibility coefficient of CP, NDF and ADF were 0.496, 0.432 and 0.346, respectively. Diet of kids was constituted by Prosopis cineraria ($900g\;kg^{-1}DM$) and Zizyphus nummularia ($100g\;kg^{-1}DM$) leaves. Digestibility of CP, NDF and ADF were 0.456, 0.415 and 0.201, respectively. DM, DCP and ME intakes were $85.8,\;6.44g\;kg^{-1}\;W^{0.75}$ and $1.22MJ\;kg^{-1}\;W^{0.75}$. Lactation phase of goat fell between October-December and tree foliage formed the major portion of the diet. Diet of lactating goat contained only 6.8% CP and 16.5% ADL. Digestibility of DM, CP, NDF and ADF was 0.567, 0.221, 0.307 and 0.233, respectively. DM, DCP and ME intakes were $108.2,\;1.62g\;kg^{-1}\;W^{0.75}$ and $1.50MJ\;kg^{-1}\;W^{0.75}$, respectively. Present study establishes that goats on semiarid range with sufficient number of fodder trees were able to meet the nutrient requirement of ewes during oestrous and bucks during breeding season. However, during lactation and active growth phase, only DM requirement is met. Thus, it is recommended to supplement concentrate mixture to goats grazing on range during lactation and growth phase.

  • The aim of this experiment was to determine the chemical composition of six commonly utilized fodder trees and shrub species in Turkey, namely Glycrrhiza glabra L, Arbutus andrachne, Carpinus betilus, Juniperus communis, Quercus libari L and Pistica lentiscus and its relationship with gas production and estimated parameters when incubated with rumen fluid in vitro. There were significant (p<0.001) differences between leaves in terms of crude protein (CP), acid detergent fiber (ADF), total condensed tannin (TCT), bound condensed tannin (BCT) and soluble condensed tannin (SCT). Crude protein contents ranged from 5.74% (Juniperus communis) to 12.59% (Glycrrhiza glabra L). Acid detergent fiber contents ranged from 25.14% (Glycrrhiza glabra L) to 39.23% (Juniperus communis). Total condensed tannin (TCT) contents of leaves ranged from 4.34% (Quercus libari L) to 20.34% (Juniperus communis). Acid detergent fiber (ADF) and total condensed tannin contents of leaves were negatively correlated with gas productions and some estimated parameters. Potential gas productions (A) of Glycrrhiza glabra L, Arbutus andrachne, Quercus libari L and Pistica lentiscus were significantly (p<0.001) higher than those of Carpinus betilus and Juniperus communis whereas gas production rate (${\mu}_{24}$) of Pistica lentiscus was significantly (p<0.001) higher than the others. Time (h) to produce 50% of total gas pool size ($T_{50}$) of Juniperus communis was significantly (p<0.001) lower than that of Carpinus betilus whereas time (h) to produce 90% of total gas pool size ($T_{90}$) of Juniperus communis was significantly lower than the others except for Pistica lentiscus. The metabolizable energy (ME) contents of leaves ranged from 8.86 to 10.39 MJ $kg^{-1}$ DM. The results obtained in this study suggested that browse species had a significant effect on chemical composition, gas production and estimated parameters of leaves. Leaves from Glycrrhiza glabra L with a considerable amount of CP had a high rank value in terms of ME. Therefore leaves from Glycrrhiza glabra L may have a high potential value for small ruminant animals in terms of rumen and whole digestibility. Leaves from other species studied require protein supplementation when they are the only feed consumed by ruminant animals.

  • Through several trials that has done for making the fertilizing-counter plan on the soil improving species, some results have been got as follows; 1. In the non-phosphorus dressing plots soil improving species have very poor survial ratio and show us to be died step by step. It may be resons that root can not make the nodule in case of non-phosphorus dressing and so tree could not absorb the nitrogen nutrient fixed by the nodule. And root competition with the weedy speces for utilizing the nutrient and oxygen in the soil could be reasons when planting in the heavy weedy rooting site. 2. Triple super phosphate, Fused Mg Phosphate and Fused super phosphate have showed the remarkable effects on the growth of soil improving species within 3rd year after planting. But Koreaan tablet fertilizer(9-12-4) for forest purpose have reacted considerably lower effect in comparision with the above powder and grain type phosphorous fertilizer. 3. In case of tablet type fertilizer tree root will have very little phosphorus absorbing surface because phosphorus can be utilized only from the tablet surface and root can not penetrate into the tablet. This my be reson to show the poor dressing reaction of tablet fertilizer but tablet fertilizer has a possibility to be utilized during long years as a sympton in photo 6. So tablet fertilizer can have a recommendation to dress much fertilizer at p]anting year and then tree root can get much more chance for absorbing the phosphorus that could keep the high survival and for utilizing it during many years without after dressing. 4. The granurar and powder type phosphate can develop the dense root mat like photo 8 because of giving the large surface for absorbing the phosphorus and weedy root can approch to the nodule for taking the nitrogen element. So this type seems to present better effect than tablet type to control the soil movement, stem weight as 200g per meter(l meter long${\times}$0.1m width). When added the lime any effect could not be found and rather give the negative effect. So Lespedeza seed sowing and phosphorus dressing system seems us to be very reasonable method for covering the raw material of basket making, fodder and fuel wood supply. 7. Fused Mg phosphate and Fused super phosphate are good fertilizer to the soil improving species and dressing more than 30g per seedling can be recommendable amount. 5. In the unproductive and dry soil with phosphorus fertilizer Robinia pseudoacacia and Alnus firnui can grow more than 2.3m in height at 3rd year and Alnus inokumae have the rapid height growth that is more than 1.8m at 2nd year. Depending on the growth situation like the above example minirotated management has possibilities and rapid covering of erosed land can be done with the soil improving species and phosphorus fertilizer. 6. In the Lespedeza sowing plot with 40g Fused Mg phosphate dressing per meter in the eroded and unproductive forest soil Lespedeza have completely covered this poor land and produced the green.
