“…The afore-mentioned variability in DG 1, DG 2 and DG 5 was finally reflected in very uniform levels of daily gains in the period from birth to 100 days of age because for example the difference in their levels between singles and twins was only 7 g. Age of dam had a significant effect on the majority of growth traits under study. Similar findings were reported by Křížek et al (1992), Burfening and Carpio (1993) and Macit et al (2001). It was also observed that BW 30, 70 and 100 of lambs increased with the increasing age of dams (from 2 to 4 years), however BW 30, BW 70 and BW 100 of lambs originating from five-years-old and older dams were approximately the same as in lambs of three-years-old dams.…”

“…With the exception of DG 1, higher daily gains were found in males in all cases. Similar findings were reported by Hammel and Laforest (2000), Dixit et al (2001), Fernandes et al (2001), Macit et al (2001), Abegaz et al (2002), and Matika et al (2003). However, it is necessary to state that the above-mentioned authors recorded higher daily gains in males in all intervals under study.…”

ABSTRACT:The effect of some factors (genotype, sex, litter size, age of dam at lambing, month of lambing and year of birth of lamb) on the growth of lambs -crossbreds between the Improved Wallachian (IW) and East Friesian (EF) breed was evaluated in operating conditions during two successive years. Three genotypes were evaluated: IW 50 EF 50, EF 75 IW 25 and EF 87.5 IW 12.5. The evaluation of the effect of genotype on growth showed that this factor did not have a significant effect on the majority of growth traits under study. In the period from birth to 100 days of age the highest daily gain was found in IW 50 EF 50 (263 g). The daily gains of EF 75 IW 25 and EF 87.5 IW 12.5 in this period were lower but identical (244 g). Age of dam had a significant effect on the majority of growth traits under study. Sex of lamb had a significant effect on body weight at 100 days of age and also on the majority of daily gains under study. The factors litter size, month of lambing and year of lamb birth were the most significant sources of variation of daily gains. As far as the non-genetic factors were concerned, the highest daily gains from birth to 100 days of age were recorded in males (259 g), in singles (260 g), in lambs from 4-years-old ewes (269 g), in lambs born in January (263 g) and in lambs born in the first year of evaluation (256 g). The analysis of phenotypic correlations indicated that body weight at birth showed a positive and highly significant (P ≤ 0.01) effect on the majority of growth traits under study. All phenotypic correlations between individual body weights were positive and high (P ≤ 0.01). The majority of phenotypic correlations between individual daily gains under study were also positive and high (P ≤ 0.01).

Growth performance (n=T58) and carcass characteristics of 5 Awassi (A), 5 Morkaraman (M) and 4 Tushin (T) lambs weaned at 2.5 months of age were evaluated. The lambs were fed a concentrate mixture and allowed to graze for 70 days. At the end of the 70-day grazing period, M lambs showed the highest daily weight gain and the amount of concentrate consumed per body weight gain. The effects of breed and sex of lamb on daily weight gain on pasture were significant (P<0.05) and highly significant (PO.01), respectively. Male lambs were superior to female lambs with respect to daily weight gain. Slaughter traits and carcass characteristics of 14 male lambs representing three fat-tailed breeds were compared at the end of the grazing period of the year in which they were born. Hot carcass weight and hindshank weight of M lambs were heavier than those of A and T lambs. M had higher hot dressing percentage and larger M. longissimus dorsi (LD) area than those of A and T lambs. Most of the weights of wholesale cuts were significantly (P<0.05; PO.01) affected by breed. It is recommended that either A, M and T male and female lambs weaned at 2.5 months of age in eastern Turkey should be fed with 450 g concentrate per head per day on pasture for 3 to 3.5 months of grazing season, or lambs should be supplemented with more than 450 g concentrate feed on pasture because native fat-tailed breeds supplemented with 450 g concentrate on pasture did not give carcasses with an adequate commercial weight in the 70-day fattening period.

Esenbuga, N., Macit, M. and Karaoglu, M. 2002. Growth performance and carcass characteristics of Awassi, Tushin and Awassi x Tushin (F,) lambs under grazing with concentrate supplementation. J. Appl. Anim. Res., 21: 57-64.Growth performalice, slaughter traits and carcass cha,racteristics of Awassi (A), Tushin (T) is fat-tailed breeds. Sheep meat production (116.000 tons) has a n important contribution to red meat production amounting to 22.5% of the total meat production (517.000 ton) of Turkey (Anonymous, 1997). On the other hand present meat production performances of native sheep breeds are far from meeting requirement (Bicer et aE., 1992). Factors affecting economical sheep meat production are higher growth of lambs and better feed conversion efficiency. There are two alternatives for genetic improvement of native sheep breeds: pure breeding of indigenous breed and crossbreeding with mutton type sire breed (Guney a n d Bicer, 1986). I n order to adopt crossbreeding it is essential to assess the performance of various crossbred animals vis a vis that of native ones. Therefore, present study was undertaken to compare the performance of one such crossbred (AwassixTushin) with that of pure Awassi or Tushin. consumption and the live weights of lambs were recorded biweekly. At the end of grazing period, 5 male lambs from A and AxT, and 4 male lambs from T breed, whose average slaughter weights were similar, were slaughtered for subsequent carcass analysis. Materials and MethodsAfter slaughter, head, skin, feet and offal were removed and weighed. The carcasses were chilled at 4C for 24h before jointing and measurements taken on intact cold carcass (Kempster et al., 1982). The fat tail was removed from each carcass prior to cutting into wholesale cuts ( Fig. 1) according to Anonymous (1973). The wholesale cuts including fat tail were weighed and recorded. Measurements included fat thickness over the longissimus dorsi (LD), the quantity of kidney and pelvic fat and LD area.The statistical analysis was conducted using the GLM procedure of SAS (SAS, 1985). The data on growth performance were analyzed by a mathematical model that included the effects of genotype (A, T, AxT), sex and type of birth (single and twin) of the lambs. All interactions investigated in this study were not included in the model because they were found not to be significant.Significant differences between means with respect to growth performance were detected using Duncan's multiple range tests (Duncan, 1955). The data concerning the slaughter characteristics, carcass measurements and carcass characteristics were analyzed by another linear model that included the effect of genotype. Results and DiscussionThe results obtained from this study on daily weight gain for A, T and AxT lambs (Table 1) are in agreement with results of Buyukburc et al. (1983) of 166 g for Akkaraman lambs subjected to semi intensive feeding on pasture. Male lambs were heavier (P
