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.

This study determined the concentrations of micro-minerals in pastures, in feed supplements and in grazing, reproducing ewes, at different times during the year, at three farms in Northern China. Samples were collected 5 to 8 times during the year and analysed for selenium, copper, iron, molybdenum and zinc. On two farms selenium concentrations in both pastures and animal tissues were low for part of the year. The lowest concentrations in pasture (< $30{\mu}g/kg$ DM) and liver (< $100{\mu}g/kg$ wet weight) indicated that productivity of the sheep may be reduced by a deficiency of this element. On one farm copper concentrations in the lever were in the liver were in the deficient range (< $5{\mu}g/kg$ wet weight) for part of the year. It is likely that this is a result of high intakes of iron from pasture (up to 4.5 g Fe/kg DM) and soil, as indicated by high concentrations of iron in faeces (up to 7 g Fe/kg DM). Molybdenum intake is unlikely to have had much influence on copper absorption because pasture concentrations of this element were not unusually high (1 to 5 mg/kg DM). Zinc in pastures on two farms was below 10 mg/kg DM for part of the year. On one of these farms, the concentration of zinc in faeces was below 30 mg/kg DM throughout the year and this is consistent with zinc intakes of 7 to 15 mg/kg. Despite these low intakes, the concentratons of zinc in plasma were consistently above deficient levels. No clinical signs of deficiencies of any of the elements studied were observed.

Objective: The objective of this study was to investigate the effect of 4-month intensive feeding on the meat quality, fatty acid profile, flavor, and growth performance of grazing Hulunbuir sheep (HBS). Methods: The HBS were selected 4-months after birth in a pasture rearing system as the experimental animals (n = 44, female, average body weight 23.8±2.2 kg) then divided equally into pasture-based grazing fattening (PAS) and concentrate-included intensive fattening (CON) groups for another 4-month finishing. When finished fattening, all animals were slaughtered to collect musculus longissimus dorsi subcutaneous adipose tissue and to investigate the influences on meat quality, fatty acid profile, flavor and growth performance. Results: The results showed lambs in CON group got significantly higher live weight, hot carcass weight, and dressing percentage. The CON group had significantly higher value of redness (a^*), lightness (L^*) and water holding capacity (p<0.05), significantly lower value of Warner-Bratzler shear force than the PAS group (p<0.05). The subcutaneous fat from CON group lambs demonstrated a significantly higher content of C18:1 and C18:2 (p<0.05), but lower C14:0 and C16:0, indicating an increased degree of unsaturated fatty acid. The content of 4-methyloctanoic acid, 4-ethyloctanoic acid and 4-methylnonanoic acid had increased 2 to 4 times, representing a more intense odor in the CON group. However, the values were still lower than most sheep breeds reported, indicating the indoor feeding system could not fundamentally deteriorate the excellent meat characteristic of HBS. Conclusion: It was evident that lambs in CON group exhibited a better meat production performance, improved in meat color, texture and healthier fatty acid profile through pasture-weaned concentrate included intensive fattening system, which offers a good alternative regimen for lamb finishing and has a wide prospection in the HBS meat industry.

The effects of sheep urine and dung patches on methane ($CH_4$) and carbon dioxide ($CO_2$) fluxes were investigated during the summer-autumn in 2010, to evaluate their contribution to climate change in a desert grassland in Inner Mongolia, China. Results indicate that the cumulative $CH_4$ emissions for dung patches, urine patches and control plots were -0.076, -0.084, and -0.114 g/$m^2$ and these were net $CH_4$ sinks during the measured period. The level of $CH_4$ intake from urine and dung plots decreased 25.7%, and 33.3%, respectively, compared with a control plot. $CO_2$ fluxes differed (p<0.01) in urine plots, with an average of 569.20 mg/$m^2$/h compared with control plots (357.62 mg/$m^2$/h) across all sampling days. Dung patches have cumulative $CO_2$ emissions that were 15.9% higher compared with the control during the 55-d period. Overall, sheep excrement weakened $CH_4$ intake and increased $CO_2$ emissions.

The understanding of seasonal forage intake of grazing deer is essential for the development of supplementary feeding strategies in southern Australia. The alkane technique is used in other animal species for estimating feed intake of individual animals and their diet composition. To assess the potential of using alkanes as a marker for predicting feed intake of fallow deer, the daily faecal recovery of alkanes and excretion rate of dosed artificial alkanes (C32 and C36) were measured with 6 deer fed three forage based diets. The artificial alkane capsule designed for use in sheep is suitable for fallow deer. Faecal samples need to be collected over days 7-19 after dosing. The daily excretion rate was 40 mg for C32 and 37 mg for C36. The faecal recovery of natural alkanes is incomplete and the faecal concentrations of alkanes need to be adjusted for an accurate estimation of intake. The actual feed intake of 6 experimental deer over a 5 day period was accurately estimated ($R^2$=0.52) using alkanes.

The effects of supplementation with mixed fodder or concentrate were investigated on the performance of a) growth of male lambs and kids grazing extensively under oil palm trees and b) reproduction of ewes and goats stall-fed with native herbage. Supplemented kids and lambs had higher average daily weight gain than controls but the effect was only significant for those which received concentrate (p < 0.05). Final body weight was only significantly different from controls for lambs supplemented with concentrate (p < 0.05). The ages at puberty, first mating, first conception and first kidding of supplemented goats were about 110 days earlier than those for controls (p < 0.05 or better). Supplemented goats had first mating and conceived at lower body weights (p < 0.01) than those in control groups. Different feeding regimes had no effects (p > 0.05) on the reproductive performance of ewes apart from highest body weight of first lambing in animals supplemented with concentrate (p < 0.05). Native herbage available under oil palm trees of 5 years old was sufficient for growth and reproduction of sheep and goats. Concentrate was better than mixed fodder as supplement for enhancing the reproductive performance of goats but both appeared to have limited effects on the performance of reproduction in ewes and growth in male kids.

Anaerobic rumen microorganisms mainly bacteria, protozoa and fungi degrade ligno-cellulosic feeds consumed by the ruminants. The ruminants in developing countries are predominantly maintained on low grade roughage and grazing on degraded range land resulting in their poor nutrient utilization and productivity. Hence, manipulation of rumen fermentation was tried during last two decades to optimize ruminal fermentation for improving nutrient utilization and productivity of the animals. Modification of rumen microbial composition and their activity was attempted by using chemical additives those selectively effect rumen microbes, introduction of naturally occurring or genetically modified foreign microbes into the rumen and genetically manipulation of existing microbes in the rumen ecosystem. Accordingly, rumen protozoa were eliminated by defaunation for reducing ruminal methane production and increasing protein outflow in the intestine, resulting in improve growth and feed conversion efficiency of the animals. Further, Interspecies trans-inoculation of rumen microbes was also successfully used for annulment of dietary toxic factor. Additionally, probiotics of bacterial and yeast origin have been used in animal feeding to stabilize rumen fermentation, reduced incidence of diarrhoea and thus improving growth and feed conversion efficiency of young stalk. It is envisaged that genetic manipulation of rumen microorganisms has enormous research potential in developing countries. In view of feed resource availability more emphasis has to be given for manipulating rumen fermentation to increase cellulolytic activity for efficient utilization of low grade roughage.

Effects on feed intake, liveweight gain and economic benefits of supplementing lambs with urea molasses blocks, were studied. Forty eight crossbred lambs were divided into 6 groups and assigned randomly to grazing on native pasture (CONT) or along with supplements of Commercial ration (COM) and urea molasses blocks (UMBs) containing two levels of cement and calcium oxide as a binding agent. Analysis of variance revealed highly significant (p<0.01) differences in dry matter (DMI, g/day), crude protein (CPI, g/day) and metabolizable energy (MEI, MJ/day) intakes. Differences in liveweight gain (LWG, g/day), feed conversion ratio (FCR) and net economic benefit of supplementation were also highly variable. The intake of DM, CP and ME varied from 974 to 1002, 66-70 and 7.6-8.4 in lambs supplemented with UMBs, significantly (p<0.01) greater than 848, 52.5 and 5.6 in lambs supplemented with COM or FCR and net economic benefits (54.3; 57.8; 17.1 and 1.96; 2.4) in lambs supplemented with COM and UMB-2, were CONT or supplemented with UMB-1, UMB-3 and UMB-4 respectively. Factors responsible for differences in feed intake, liveweight gain and economic benefits, are discussed.

생체중(生體重)과 일당증체량간(日當增體量間)에 높은 상관(相關)을 보여 주었고 기타(其他) 형질(形質)사이에서는 별로 상관(相關)이 없었으나 흉추(胸椎)길이와 생체중(生體重), 일단증체량(日當增體量), 정육율간(精肉率間)에서는 비교적(比較的) 높은 상관(相關)이 나타나고 있다. 재래산양(在來山羊)에 잇어서는 생체중(生體重)과 일당(日當) 증체량(增體量) 사이에 높은 상관(相關)이 있었으며 도체중(屠體重)과 정육량(精肉量) 사이에도 비교적(比較的) 높은 상관(相關)이 있었으나 내장중(內臟重)과 생체중(生體重), 일당(日當) 증체량(增體量) 사이에는 부(負)의 상관(相關)을 보여주고 있다. 2) 면양(緬羊)의 산모성(産毛性) 형질(形質) 상호간(相互間)의 상관(相關)에서는 산모량(産毛量)과 생체중(生體重), 일당(日當) 증체량(增體量), 산모율간(産毛率間)에 1% 수준(水準)에서 높은 상관(相關)을 나타내고 있어 성장(成長)이 빠른 개체에 산모량(産毛量)도 많다는 것을 추정할 수 있었다. 3) 산육성(産肉性) 형질(形質)과 체척측정치(體尺測定値) 사이의 상관(相關)은 면양(緬羊)에서는 생체중(生體重), 정육중(精肉重), 내장중(內臟重)과 흉위(胸圍), 체장(體長)사이에서 제일 높았고, 도체중(屠體重), 정육중(精肉重)과 비교적(比較的) 높은 부위(部位)는 흉폭(胸幅), 흉심(胸深)이었다. 따라서 면양(緬羊)의 체척측정(體尺測定)에 중점(重點)을 두는 것이 유효(有效)할 것으로 생각된다. 재래산양(在來山羊)의 산육성(産肉性) 형질(形質)과 체척측정치(體尺測定値) 사이에는 체척부위(體尺部位)의 대부분이 산육성형질(産肉性形質)과 높은 상관(相關)을 나타내고 있으며 특히 흉위(胸圍)와 생체중(生體重), 도체중(屠體重), 정육중(精肉重), 골격비율(骨格比率)사이에서는 0.922~0.974의 높은 상관(相關)을 보여주고 있다. 한편 산육성(産肉性) 형질(形質)과 흉심(胸深), 전관위(前管威), 체장(體長)사이에도 각각(各各) 0.759~0.911, 0.759~0.909, 0.708~0.872의 비교적(比較的) 높은 상관(相關)을 나타내고 있다. 따라서 재래산양(在來山羊)에 대한 산육성(産肉性) 추정(推定)은 흉부(胸部)에 대한 c체척치(體尺値)가 상당히 큰 의의(意義)가 있을 것으로 본다. 5. 혈액상(血液像) 및 혈장성분(血漿成分) 1) 적혈구수(赤血球數)와 평균(平均) 혈색소농도(血色素濃度)는 재래산양(在來山羊)이 각각(各各) $12.93{\times}10^6/mm^3$와 36.26%에 대하여 유의성(有意性)이 인정(認定)되는 높은 값을 나타냈다. 2) 혈색소량(血色素量), 적혈구용적(赤血球容積), 평균(平均) 적혈구용적(赤血球容積) 및 평균혈색소량(平均血色素量)은 재래산양(在來山羊)이 각각(各各) 10.92g/100ml, 3.02ml/100ml, $23.40{\mu}^3$ 및 10.94pg로서 면양(緬羊)의 11.73g/100ml, 36.25ml/ml, $33.97{\mu}^3$ 및 8.43pg에 비하여 낮은 값을 나타냈는데 모두 유의성(有意性)이 인정(認定)되었다. 3) 백혈구(白血球)의 수(數)는 재래산양(在來山羊)이 $11.64{\times}10^3/mm^3$을 나타내어 면양(緬羊) $9.32{\times}10^3/mm^3$보다 유의(有意)하게 높은 값을 나타냈다. 4) 백혈구(白血球)의 감별(鑑別) 수(數)에 있어서 호염구(好鹽球)는 재래산양(在來山羊)이 임파구(淋巴球)는 면양(緬羊)이 유의(有意)학 높은 값을 나타냈으며 호염구(好鹽區), 호산구(好酸球) 및 단핵구(單核球)는 차이(差異)가 없었다. 5) 혈장중(血漿中)에 함유(含有)되어 있는 총단백질(總蛋白質)과 포도당(葡萄糖)의 양(量)은 재래산양(在來山羊)이 각각(各各) 62g/100ml와 53.6mg/100ml로서 면양(緬羊)의 5.6g/100ml와 45.7mg/100ml보다 유의(有意)하게 높은 값을 나타냈으며, 총지질(總脂質)의 양(量)은 재래산양(在來山羊)이 127.6mg/100ml로서 면양(緬羊)의 149.6mg/100ml보다 유의성(有意性)이 인정(認定)되는 낮은 값을 나타냈다. 6) 비단백질태질소화합물(非蛋白質態窒素化合物), Cholesterol, Ca, P, K, Na 및 Cl의 함량(含量)은 면양(緬羊)과 산양간(山羊間)에 차이(差異)가 없었다. 6. 경제성분석(經濟性分析) 1) 면양(緬羊)과 산양(山羊)을 196일간(日間) 사육(飼育)하였을 때 농가수익(農家收益)은 1두당(頭當) 4,000원 정도(程度)였으며 농가(農家)에서 부업(副業)으로 사육(飼育)할 수 있는 적정규모(適正規模)는 5~10두(頭)이다.
