“…T 3 group achieved comparatively lower weight gains than other treatment groups, indicated that extensive farming system has limited feeding resources and exposure to varied environmental conditions might have resulted in loss of body reserves for grazing activities which might have resulted in poor body weight gains. The results of the present study were in concurrence with the findings of (Zervas et al, 1999;Porwal et al, 2005 andBharambe andBurte, 2012) who reported higher body weight gains for the lambs reared under semi-intensive and intensive system of feeding when compared to extensive system. Carvalho et al, (2007) observed that increase in roughage with decrease in concentrate in the diets decreased the live weight gain of the lambs fed diets.…”

“…Higher plane of nutrition and efficient conversion into edible meat is the resultant effect of intensive system. Zervas et al, (1999) reported that, the carcass weight of lambs kept on pasture was lower, but omental and perinephric fat were significantly heavier in animals fed concentrate feed indoor. The meat: bone ratio was in the range of 1.89:1(T 3 ), 1.92:1(T 2 ) and 2.22:1 (T 1 ) indicated that significantly (p<0.05) higher percentage of meat weight obtained in intensive system.…”

The present study was carried out to assess the effect of different farming systems on productive performance, body condition score and carcass characteristics of Deccani lambs. Thirty-six weaned lambs having 3 months of age were divided into three groups with twelve lambs in each group in under intensive (T 1 ), semi-intensive (T 2 ) and extensive (T 3 ) farming systems. The comparative mean dry matter intake (kg/day) and (kg/100kg BW) was significantly (p<0.05) higher in T 1 group when compared to other groups. T 2 group had significantly (p<0.05) higher DM intake (kg/day) than T 3 group. The mean values of Average daily gains in Deccani lambs were significantly (p<0.05) higher in T 1 group compared to T 2 and T 3 groups. The feed efficiency was significantly (p < 0.05) higher in T 1 compared to T 2 , T 3 groups. Statistically significant difference was found in BCS at six months of age (p<0.05) between T 1 and T 3 groups. BCS at 9, 12 months and overall BCS, there was a significant (p<0.05) difference between T 1 and T 3 groups. T 1 group had higher pre-slaughter weight, hot carcass weight, meat %, fat% and meat: bone ratio thanT 2 and T 3 . The dressing yields were comparable. The weights of other offals (heart, kidney, spleen, testicles, blood, head and lung and trachea) were comparable. The findings of this study indicated that the intensive and semi-intensive system of rearing could be useful for mutton production. In extensive system, which is predominant in India should change its facet by enriching the grazing land resources as well by the supplementation of required plane of nutrition during growth and special life stages viz., gestation, puberty, post lambing and finisher stages for achieving optimum productivity.

“…Fanchone@antilles.inra.fr In the same way, in direct comparisons between animals fed indoors and animals fed at pasture, the animals fed indoors often received a high proportion of supplements, whereas animals at pasture did not (Keane and Allen, 1998;Zervas et al, 1999;Moniruzzaman et al, 2002;Raghuvansi et al, 2007). In addition, the forage on offer was not the same indoors and at pasture.…”

The effect of two feeding systems (indoors and at pasture) on intake and digestion of fresh grass was studied at two stages of regrowth (21 and 35 days of regrowth) in two parallel experiments. In Experiment 1, 10 adult Martinik rams weighing, on average, 50.5 (60.9) kg, including four fitted with rumen cannula, were randomly allocated to two groups according to a 2 3 2 Latin Square design. These rams consumed a 21-day regrowth of Digitaria decumbens grass diet during two successive 28-day periods, indoors (five rams) or at pasture (five tethered rams). In Experiment 2, 10 other Martinik rams weighing, on average, 45.5 (60.9) kg, including four fitted with rumen cannula, were randomly allocated to two groups according to a 2 3 2 Latin Square design. These rams consumed a 35-day regrowth of D. decumbens grass diet during two successive 28-day periods, either indoors (five rams) or at pasture (five tethered rams). For the indoors groups, in vivo organic matter digestibility (OMD) was measured by total collection of feces. In addition, OMD was estimated indoors and at pasture using the fecal CP (CPf ) method (OMD CPf ). Organic matter intake (OMI) was then estimated using OMD CPf and fecal organic matter output (OMI CPf ). Correlations of 0.49 and 0.77 were found between in vivo OMD and OMD CPf (P , 0.05) and between OMI and OMI CPf (P , 0.001), respectively. OMD CPf was 1.8% (P , 0.05) and 2.7% (P , 0.01) lower indoors than at pasture at 21 and 35 days of regrowth, respectively, whereas OMI CPf indoors was 1.1 and 1.16 times that registered at pasture at 21 and 35 days of regrowth, respectively. The higher OMD CPf at pasture was linked to the higher selective behavior of rams at pasture, whereas the differences in OMI CPf between the two feeding systems were linked to differences in the total bulk density of the grass. These studies show that differences in OMD CPf and OMI CPf exist between animals fed indoors and at pasture with the same forage and that these differences may vary according to the stage of regrowth of the grass offered.

“…As well known, meat quality of sheep is affected by breed, vegetation and feeding practices. Various aromatic compounds in natural vegetation during grazing may also affect the lamb meat quality (Kempt et al, 1981;Zervas et al, 1999;Özbey et al, 2000;Prioloa et al, 2002;Santos et al, 2008). It has been reported with previous studies (Esenbuğa et al, 2009;Yakan and Ünal, 2010) that there are important differences in animal feeding among geographical regions and even among districts.…”

“…These approaches include methods of lamb fattening within the extensive production system, performed according to regional conditions that can also be called "traditional" or "local" conditions. Non-breeding male Chios lambs commonly raised in Ege Region reach slaughter weight in early ages under intensive feeding conditions (Economides et al, 1990;Altınel et al, 1998, Zervas et al, 1999. However for healthier meat production with sensory attributes based on the changing consumer demands, producers prefer traditional feeding methods in animal production (Oliván et al, 2009).…”
