“…Our study's results for gender in terms of live weight was expected and in agreement with past studies (Mayaka et al, 1995;Fourie et al, 2002;Erol and Akçadag, 2009;Cam et al, 2010;Yilmaz et al, 2014a;Yilmaz et al, 2014b).…”

“…Although the live weight results in our study genotypes were lower when compared to Karayaka, Akkaraman and Dorset Down x Akkaraman, the body length (BL) was in fact longer than those breeds for the similar age (Şireli and Ertuğrul, 2005;Cam et al, 2010). Many of research were reported higher chest girth value than the data obtained from the present study (Fourie et al, 2002;Şireli and Ertuğrul, 2005;Cam et al, 2010;Yilmaz et al, 2013).…”

Ultrasonic measurements of Musculus longissmus dorsi thoracis et lumborum (MLD)were taken of Dorper (n=99) and Dorper x Merino (n=65) lambs at 156 days of age and comparisons made to various body dimensions to ascertain whether sex, genotype, birth type and live weight had any effect on these parameters. Lambs were weaned two months after birth and placed ad libitum on basic dry land pasture during the draught spring and summer months of 2014 in the arid southeastern region of Turkey. Least square means of backfat thickness, skin+backfat thickness, muscle depth, body length, chest girth and live weight, at the mean age of 156 days, were 0.17 cm, 0.32 cm, 1.75 cm, 63.30 cm, 72.37 cm and 25.16 kg, respectively. Genotype was a statistically significant factor in terms of back fat thickness (BFT), skin and backfat thickness (S+BFT), muscle depth (MD), body length (BL) and live weight (LW). The study showed that Dorper and Dorper x Merino genotypes into Turkey show a clear advantage over the native breeds in terms of meat production and quality not to mention the high potential for lean carcass production. Ultrasonic measurements of Longissimus thoracis et lumborum (MLD) will provide an important contribution to selection index in breeding programs for Dorper and Dorper crossbred genotypes. However estimation of genetic parameters are required in containing a pedigree database in order to establish an effective selection index.

“…Furthermore, the result of current study confirmed the widely accepted interaction between sire breed and sex on liveweight and body conformation measurements, the basis of which has been extensively studied in the last decade (Afolayan et al, 2006;Cam et al, 2010;Fogarty et al, 2005a;Fogarty et al, 2005b;Hopkins et al, 2007b;. Thus, a demonstration of the strong positive correlations between body measurements and liveweight in our present study reaffirms current consensus (Abbasi and Ghafouri-Kesbi, 2011;López-Carlos et al, 2010;Otoikhian et al, 2008;Sowande and Sobola, 2008).…”

“…Lamb productivity is a derivative of feed nutrition (Black, 1983;Geesink and Zerby, 2010;Hopkins et al, 2007b;McLeod et al, 2010) as growth rates and liveweights are foremost indicators of operational profitability (Afolayan et al, 2006;Cam et al, 2010). Profitability in dual-purpose meatsheep production is driven primarily by protein-rich feed supplementation.…”

The hypothesis that supplementation with Spirulina will increase liveweight, growth and body conformation with significant interactions between sire breed and sex was tested using purebred Merino weaners and first-cross weaners from Merino dams sired by Dorset, Black Suffolk and White Suffolk rams under the same pasture-based management system. Our experimental objective was to evaluate the effects of varying levels of Spirulina supplementation, sire breed and gender on liveweight and body conformation traits. We utilized a complete randomized block experimental design balanced by 4 sire breeds, 3 supplementation levels and 2 sexes in which weaned prime lambs with an average liveweight of 37.6 ± 5.2 kg and body condition score of 3.1 ± 0.4 at 6 months of age were balanced by sire breed and gender and randomly allocated into 3 treatments (8 lambs per treatment) -the control group grazing without Spirulina (0%), low (10%wt/vol) and high (20%wt/vol) Spirulina. Lambs in the low and high Spirulina treatment groups were drenched daily with Spirulina prior to being released for grazing with the control group of lambs over a 6-week trial period, following a 3-week adjustment phase. Weekly measurements of chest girth, withers height, body length, body condition score and liveweight were taken. Mixed linear model procedures in SAS with sire breed, sex, Spirulina level and their second order interactions as fixed effects and sire as a random variable, were used for statistical analysis. Spirulina level significantly influenced lamb liveweight (P<0.018), body condition score (P<0.001) and body length (P<0.015). Lambs on Spirulina levels of 10% recorded the highest mean liveweight of 41.9 ± 0.7 kg. Spirulina levels of 20% did not significantly improve liveweight compared to the control group (0%).

Body conformation (P<0.001) and liveweight (P<0.014) responses to Spirulina supplementation significantly varied between ewe and wether lambs. It was evident that a cost-effective supplementation strategy with Spirulina for optimal liveweight gains in weaner lambs was achieved at the 10% level. These findings will aid sheep farmers in making informed choices about appropriate sire breed and gender combinations in their enterprises when supplementing with Spirulina for growth improvement as a strategic pathway for the early attainment of market weights in prime lambs. We concluded that based on the empirical experimental evidence within the scope of this study, the tested hypothesis is acceptable.

Genetic parameters of production and reproduction traits were estimated using 39,926 records from 5,860 individual progenies of 163 sires and 1,558 dams. The data were collected at Makuie Sheep Breeding and Raising Station (Maku, Iran) from 1989 through 2013. Nineteen traits were classified in four main groups: a) live body weight traits, b) body measurement traits, c) greasy fleece weight traits, and d) reproduction traits. Year of birth, lamb sex, age of dam, and birth type were considered as fixed effects in the animal model. Four different animal models that are differentiated by including or excluding maternal effects were fitted for each trait. The Akaike information criterion was used to determine the most appropriate model for each trait. Parameters were overestimated substantially when maternal effects, either genetic or environmental, were ignored from the models. By ignoring the maternal effects, the traits could be classified into three main groups: body live weight traits with high heritability (0.34-0.46), body measurement and greasy fleece weight traits with medium heritability (0.11-0.27) and reproduction traits with low heritability (0.03-0.20). The genetic correlations among the traits ranged from-0.41 to 0.99. The estimated genetic parameters may be used to set up short/long term breeding program for the selection purpose of Makuie sheep breed.
