“…The highest genetic and phenotypic correlations were observed between YW and HG. Therefore, body live weight can be predicted via body measurements in pasture as reported by Atta & El Khidir (2004). The results are almost similar to the reports on Belgian blue du Main, Suffolk, and Texel sheep (Janssens & Vandepitte, 2004) and Yankasa lambs (Yakubu, 2010).…”

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.

“…Increasing the energetic density had a positive influence on the lambs' measured biometrics. These results were similar to found by Muhammad and Tukur (2013); however, they were different from those verified by Atta and El Khidir (2004), who did not find a positive effect on body measurements, but the diets the authors supplied were iso-nitrogenous and had the same energy values. In this regard, they were different from the diets used in the current study, because we supplied increased energy diets.…”

Effects of different hay: concentrate ratios on body and testicular-epididymal biometry and metabolic profile of Santa Ines lambs

et al. 2016

This study was carried out to verify the effects of different hay: concentrate ratios on body, testicular and epididymal development and metabolic profile of hair sheep lambs. Twenty-nine Santa Ines lambs were used. Treatments consisted of diets with different hay: concentrate ratios (100: . The characteristics evaluated were: body weight (BW), body condition score (BCS), hearth girth (HG), body length (BL), height at withers (HW), height at rump (HR), rump width (RW), chest width (CW), scrotal perimeter (SP), testis length (TL) testis width (TW), testis thickness (TT), cauda epididymal length (CEL), cauda epididymal width (CAW), cauda epididymal thickness (CET), scrotal skin thickness (SST) and testicular volume (TV). Blood samples were collected to analyze glucose, urea, albumin, total cholesterol, total proteins, inorganic phosphate and magnesium concentrations. The body and testicular-epididymal measurements increased linearly with increases in the energy concentration in the diet. BW, BL, CW, RW, HG and BCS showed positive high correlations (r = 0.71 to 0.94) with all testis-epididymal measurements. The results of the metabolic profile study showed interactions between the addition of the concentrated feed and time of blood collection on total proteins, albumin, urea, cholesterol, phosphorus and magnesium concentrations. At the beginning of the trial, hypoproteinemia and hypoalbuminemia were verified in T3 and T4. However, the indices returned to normal over time with the continuity in the diet supplied. Hypomagnesaemia was verified in all treatments. The plasmatic phosphorus concentration was sufficiently high at the end of all treatments, except control. In conclusion, the BL, HG, CW, RW as well as the BCS may be used to estimate the development of the testes and epididymis. The metabolic profile results verified that adjusts are necessary in the amount of concentrated feed given to the lambs when Tifton 85 hay (Cynodon spp) is provided to the animals. ResumoEste estudo objetivou verificar os efeitos de diferentes proporções de feno: concentrado sobre o desenvolvimento corporal, testicular e epididimário, bem como, sobre perfil metabólico de cordeiros deslanados. Foram utilizados vinte e nove cordeiros Santa Inês. Os tratamentos foram constituídos de dietas com diferentes proporções de feno: concentrado (100: 0-Controle; 80: 20-T1, 60: 40-T2, 40: 60-T3 e 20: 80-T4). As características avaliadas foram: peso corporal (PC), escore de condição corporal (ECC), perímetro torácico (PT), comprimento do corpo (CC), altura na cernelha (AC), altura na garupa (AG), largura da garupa (LG), largura do peito (LP), perímetro escrotal (PS), comprimento do testículo (CT) largura dos testículos (LT), espessura de testículo (ET), comprimento da cauda do epidídimo (CCE), a largura da cauda do epidídimo (LCE), espessura da cauda do epidídimo (ECE), espessura da pele escrotal (EPE) e volume testicular (VT). Amostras de sangue foram colhidas para análise de glicose, ureia, albumina, colesterol total, proteínas totais, f...

“…the african dwarf sheep showed that head length and hip width are strongly correlated with body weight than others [5]. This fact is also supported by the research results on the Nilotic sheep , in which the body length and height at wither have a positive correlation with body weight [6]. Other research has been done on the local sheep in Indonesia ,garut sheep, that have a strong correlation between body weight to body length, height at wither, and chest depth [7].…”

Morphological index could be used to evaluate type and function of livestock. The aim of this study was applying morphological index to assess the type and function of Sapudi fat tail sheep. About 65 head ewes comprising 32 ewes from Gayam village of Gayam district and 33 ewes from Talaga village of Nonggunung district were analysed. Morphology observed were body weight, body length, height at wither, heart girth, chest width, chest depth, hip width, rump height, rump length, tail length, and tail width. Index used were weight, height slope index, length index, width slope index, depth index, foreleg length index, balance, and cumulative index. Data of morphology obtained were analysed by descriptive and pearson correlation. The results show that the average of body measurements of Gayam fat tail sheep was higher than that of Talaga fat tail sheep. Talaga fat tail sheep had balance better than that of Gayam fat tail sheep. Sapudi fat tail sheep were high type and potential to be developed as meat animal.
