This study was conducted on a total of 776 goats (part of Central highland goat breeds of Ethiopia), 306 from Boset district of Oromia region and 470 were from Minjar Shenkora district of Amhara region. A format developed by using food and agriculture organization discerption list was used for recording of morphological traits, bodyweight and linear body measurements. Both qualitative and quantitative traits were recorded from randomly sampled mature goats and the data were analyzed using SAS software. The goat type in the study area was characterized by a higher proportion of plain coat color patterns (62.5). Ingeneral, the majority (98.4%) of the studied goats were horned and characterized by backward orientation (67%) with a straight shape (49.3%). They presented a concave facial profile (73.8%), slop up toward the rump back profile (66.2%), no wattle (99.6%), no toggle (90.7%), no ruff (85.9%) and no beard (57.3%). The location had a significant effect on body weight and some other linear body measurements. Traits like body length, rump length, horn length, head length, head width and shin circumference were significantly higher in Boset district. In contrast, rump width and cannon bone length were significantly lower. The mean body weight of male goats in Boset and Minjar Shenkora district were 30.5±1.05 kg with a range of 16 to 47 and 27.5±0.56 with a range of 13 to 57, respectively. While for female counterpart mean body weights (kg) were 28.4±0.35 with a range of 17 to 45 for Boset and 27.5±0.33 with a range 15 to 57 for Minjar Shenkora district. Heart girth had the highest correlation with body weight in both sexes and shoulder width in Boset male goats. The wider variation in most quantitative measurement traits would open an opportunity for further improvement, conservation and utilization work.

The present experiment was carried out to study the body weight and its relation with the linear body measurements of pre-weaned piglets fed with different feed formulation viz., T0 (fed conventional creep feed), T1 (fed 5% milk powder supplemented creep feed), T2 (fed probiotics supplemented creep feed ) and T3 (fed creep feed supplemented with 5% milk powder and probiotics). The final body weights at 8th weeks of age were highest in T3 (12.395 ± 0.051 kg) followed by T2 (11.230 ± 0.094), T1 (9.940 ± 0.103) and T0 (8.781 ± 0.073). These findings indicated a positive effect of added supplement in the body weight of pre-weaned piglets. The results showed that the linear body measurements of the piglets maintained a positive correlation with body weight and increased steadily with a significant effect (p 0.001) of treatment on all three traits. piglets, probiotics.

This study was conducted as a preliminary study to design the breeding activity of Mongolian cashmere goats. To characterize the phenotypic traits of goats in Western Mongolia, the linear body measurements and cashmere yield and its the quality were measured. In this study, 608 cashmere goats were selected from the areas where it highly affected to overgrazing and overstocked in this area. The study used a random sampling method from the populations. The normality of the data was checked using the Shapiro-Wilk normality test and analyzed using the linear model procedure in R software. All male (buck) and female goats had straight head profiles (100%). Black coat color was predominant in Erdeneburen, Bayan-Uul soums and all of the goats in Ulgii soum were red. The goats in Ulgii soum were the biggest in body size compared to Erdeneburen and Bayan-Uul in Ulgii soums. The goats had back horn orientation (100%). Significant effects (p <0.001) of sex, age, locations, and sex*age classes were observed on live body weight, cashmere quantitative and qualitative characteristics, and linear body measurements.

The prediction of live body weight from six body measurements was studied using the Cobb broiler strain. A total of two hundred and sixty four chicks comprising of one hundred and thirty four at males and females were used. Mean body weights day-old, 3, 6, 9, and 12 weeks of age were 36.7g, 276.16g, 856.72, 1,334.1g and 1,762g respectively for the sexes combined. Males were generally more uniform in body weight and the body measurements than the females as indicated by the lower coefficient of variability (2.53% vs 3.38% for body weight at 3 weeks of age). The males were slightly (P<0.05) heavier than the females at 9 and 12 weeks of age. Cumulative weight gain was more rapid between 3 and 6 weeks of age and decreased with age up to the 12th week. The correlations, linear and stepwise regression equations reveal linear relationships between body weight and all body measurements (Body length, Body girth, Keel length, Shank length, Drumstick length and Shank thickness). Live body weight of bird was best predicted singly using keel length at 3 and 9 weeks of age and body girth and the 12th week. However with a combination of two to four of the body measurements, the prediction efficiency was enhanced.

Abstract Background An exploratory field research was conducted in northwestern Ethiopia, to characterize the morphological features of Arab and Oromo goat populations as an input to design community-based breeding programs. Ten qualitative and nine quantitative traits were considered from 747 randomly selected goats. All data collected during the study period were analyzed using R statistical software. Results Plain white coat color was predominantly observed in Arab goats (33.72%) while plain brown (deep and light) coat color was the most frequent in Oromo goats (27.81%). The morphometric measurements indicated that Oromo goats have significantly higher body weight and linear body measurements than Arab goats. Positive, strong and highly significant correlations were obtained between body weight and most of the body measurements in both goat populations. The highest correlation coefficients of chest girth with body weight for Arab (r  =  0.95) and Oromo (r  =  0.92) goat populations demonstrated a strong association between these variables. Live body weight could be predicted with regression equations of y  =  − 33.65  +  0.89  ×  for Arab goats (R2  =  90) and y  =  − 37.55  +  0.94  ×  for Oromo goats (R2  =  85), where y and x are body weight and chest girth, respectively, in these goat types. Conclusions The morphological variations obtained in this study could be complemented by performance data and molecular characterization using DNA markers to guide the overall goat conservation and formulation of appropriate breeding and selection strategies.

Heart girth (HG), body length (BL), leg length (LL), metacarpal circumference (MC), withers height (WH) and hook width (HW) of 233 growing rams of three synthetic strains, Suffolk and Finnsheep breeds were measured at 6, 8 and 10 mo of age. Thereafter, subsequent measurements were taken at 11–13 mo, 18–21 mo and 23–25 mo of age. Breed, birth period (hysterectomy derived birth date), age of ram and body weight (BW) had important effects (P < 0.05) on linear body measurements, whereas age of dam did not (P > 0.05). Significant effects of litter size on HG and BL were observed at 6 and 8 mo of age, respectively. All linear body measurements increased from 6 to 21 mo of age, whereas BL, WH and HW continued to increase to 25 mo. Rams of Strain 1, developed as a synthetic sire strain, with a large proportion of Suffolk background were generally similar to the Suffolk rams in all body measurements except for HG which was significantly larger than in Suffolk rams. The Finnsheep rams had smaller HG, BL, MC and HW than the synthetic strains and Suffolk rams, whereas LL and WH of the Finnsheep and Suffolk rams were similar. Rams of Strains 2 and 3, developed as synthetic dam strains with 50 percent Finnsheep background, were similar in body measurements. The synthetic dam strains did not differ from Strain 1 and/or Suffolk with respect to HG, BL, WH and HW. However, Suffolk rams had larger MC and shorter LL compared to those of the Strain 2 and 3 rams. Birth period had a significant effect on HG, BL, LL and MC, but no consistent trend with age of ram was apparent. Linear body measurements were positively correlated with each other and with body weight; however, the relationship varied as rams progressed in age. The importance of breed, birth date, age of ram and body weight on body measurements and the requirements for appropriate adjustments is emphasized. Key words: Sheep, body measurements, breed, birth date, age of ram

Measurements of body conformation in sheep are of value in judging the quantitative characteristics of meat and also helpful in developing suitable selection criterion. Data on 349 Harnali sheep for body length (BL), body height (BH), heart girth (HG), paunch girth (PG), tail length (TL), head circumference (HC), ear length (EL), ear width (EW), face length (FL) and adult body weight (ABW) were analysed to study the relationship between linear body measurements and body weight. The mixed linear model with dam’s weight at lambing as covariate was used to study the effect of non-genetic factors on body measurements and body weight. High estimates of heritability were obtained for BL, BH, HG, TL, HC, EL, EW, FL and ABW while moderate estimate was obtained for PG. The phenotypic correlations of BL, BH, HG, PG, HC and FL with ABW were positive and significant (0.32±0.04 to 0.59±0.08). The genetic correlations of HG, PG, HC and FL with ABW were 0.51±0.13, 0.42±0.19, 0.44±0.13 and 0.43±0.15, respectively. Various combinations of linear type traits to predict ABW were found to have coefficient of determination as high as 0.92. It is concluded that heart girth is the most important trait for estimation of live weight in sheep and the prediction equation is Body weight = -63.72 + 1.23 HG with R2 = 0.87.

Majority of the Kargil sheep populations are indigenous. Very scanty information is available for morphological characterization of Purky sheep population. Therefore, the present study was undertaken with the objectives to study the morpho-metric characteristics and body measurements for phenotypic characterization of the local sheep. A stratified random sample survey was conducted on various parameters (horn size, tail size, chest girth, punch girth, body length, height at wither and body weight) in seven different age groups. Data were collected randomly from 510 sheep of either sex. The local sheep population of Kargil which was selected for the present investigation is named as ‘Purky’ by the name of the community that reared this breed. In Purky sheep white body colour was predominant in both the sexes. The sheep breed was of low to medium body weight. The chest girth, punch girth, height at withers of Purky sheep showed it to be medium sized. Sex had significant effect (P is less than 0.05) on height at wither only. For males the least squares means were higher for all the traits of all age groups baring few exceptions. The phenotypic correlations of age groups with different morpho-metric traits were very high. The phenotypic correlations of body weight with other body measurements like tail size, chest girth, paunch girth, body length and height at wither were very high. Further studies should be carried out to fully exploit their genetic potential and to register the breed and in-situ conservation of this population.
