“…Results of fattening of Large Yorkshire pigs housed in semi-open system, but slaughtered at different body weights (125.22 and 108.52 kg) show that the composition of individual carcass side parts changes, but the meat contents in carcasses was almost equal in booth groups (47.04 % and 47.20 %) (Kuzelov et al, 2011).…”

Objective of this paper was to determine the composition of carcass sides and quality of meat obtained from two groups of fatteners (male castrated pigs) of Swallow-Belly Mangalitsa breed. First group was reared in an open system (SO, n=13) and the other group in farm conditions with free ranges (SI, n=10). Animals were slaughtered in the same slaughtering facility. Left carcass sides were dissected and percentage of meat (Actual LMP) calculated according to EU reference method (EC, No 1249/2008). Data obtained in the study was analyzed using GLM procedure of the program package SAS 9.1.3 (SAS Inst.Inc., 2002-2003).Average pre slaughter body weight of fatteners was 103.83 ± 10.13 kg. Housing and nutrition system in production of fatteners had statistically highly significant effect (p<.0001) on pre-slaughter age of fatteners. Statistically significant differences were obtained only in mean values obtained for back fat measured on single location/position-lower back (BFR I) between fatteners of groups SO and SI. Total weight of all individual carcass side parts and weight of relevant muscle tissue, depended on the weight of warm carcass sides (WHC) but not on the housing system (SBF). Carcass sides of fatteners contained in average 35.64 ± 4.39% of muscle tissue (Actual LMP). Meat content in carcass sides (Predicted LMP) was determined according to Rulebook/Pravilnik (1985) for fatty pig breeds and it was 29.67 ± 1.27%. In the musculus longissimus dorsi (MLD) of fatteners reared in closed system, was recorded higher content of water (p=0.0069), lower content of total fats/lipids (p=0.0081) and higher content of ash (p=0.0392) compared to animals from the open system of housing. No statistically significant differences in average protein content (p=0.5940) and pH 1 value (p=0.0659) were established between fatteners reared in open and closed system of housing.

The study was conducted in Sekhukhune District of the Limpopo province, South Africa where the goats between the ages of 20 and 30 months were used. A total of 613 indigenous goats of both sexes (62 male and 551 female) were selected and body weight and four morphological traits were taken on each goat in the morning before they were released for grazing. Means, standard deviations (SD) and coefficients of variation (CV) were calculated. Pair wise correlations among body weight and morphological traits were also determined which ranged from 0.81-0.91 for male and 0.72-0.89 for female goats, respectively and were statistically significant (P<0.01). The direct effect of heart girth on body weight was strongest in both sexes (path coefficient of 0.58 and 0.62 in males and females, respectively). Body length in males and body length and hip height in females also positively (P<0.05) influenced body weight. The direct effects of other linear type traits on body weight in both sexes were non-significant. The forecast indices obtained in this study could aid in weight estimation, selection and breeding programmes.

A total of 163 Sahelian goats of both sexes (64 males and 99 females) were randomly sampled and used in this study to assess the relationship between bodyweight and morphological traits using multivariate path analysis method. Methods: Data were obtained on bodyweight (kg), height at withers (HW), body length (BL), paunch girth (PG) and heart girth (HG). Means (+SD and CV) and correlation coefficients between bodyweight and morphological parameters were also evaluated using the statistical procedures of SPSS 20.0 package. Results: Higher significant (P<0.05) values were obtained for female goats in all the variables than males. The phenotypic correlation values between bodyweights and linear measurements were positive and highly significant (r = 0.707 -0.803; P< 0.01 and r = 0.520 -0.752; P< 0.01) in male and female goats respectively. Results also revealed that the direct effect of paunch girth on bodyweight was strongest (path coefficient = 0.413; P<0.05) for males while body length was strongest (path coefficient = 0.373; P<0.01) for female goats. Conclusions:The forecast indices recorded in this work could be employed to predict bodyweight in Sahelian goats with accuracy. Significance and impact of study: The prediction model obtained in this study would be useful in weight estimation and in the process help in making management decision and breeding programs for genetic improvement in goats.
