The Growth During Suckling Period and Carcass Traits of Kids of the Balkan Goat Breed
Macedonian Journal of Animal Science, 2011
The growth traits of 56 kids (31 male and 25 female) of the Balkan goat breed. reared in karst area of Montenegro during 3 months of the suckling period (birth weight,. body weight with 30. 60 and 90 days of growth and corresponding average daily gains) have been investigated. Weight and dressing percentage of warm carcasses, weight and dressing percentage of chilled carcasses, as well as weight and share of the offal and byproducts of slaughtering have been investigated on total of 14 carcasses (7 male and 7 female) and the differences that are manifested between the sexes. The average birth weight of male kids was 3.25 kg and 3.19 kg of female kids, while body weight of male kids with 30, 60 and 90 days were: 7.97, 12.74 and 17.63 kg, and for female kids: 7.78, 11.72 and 16.25 kg, respectively. Male and female kids showed statistically significant differences (P<0.01) for body weight and average daily gain in periods from 30 th to 60 th day and from 60 th to 90 th day, but not for birth weight and for ADG from birth to 30 th day. The average dressing percentage weight of warm carcasses of male and female slaughtered kids separately were 57.76 and 59.12%, weight of chilled carcasses with head and offal 56.39 and 57.47% and weight of chilled carcasses without head and offal 44.82 and 45.31%, respectively. Significant difference between sexes was determined only for weight and dressing percentage of chilled carcasses with head and giblets (P<0.05). The share of edible and non edible offal of slaughtering (pre-stomach and small intestines + abomasums and large intestines) was 9.87 and rest 8.64% in male and female kids, while the share of skin was 7.6 and 8.2% in average,. respectively.

This study was conducted to investigate effects of slaughter age and gender on carcass characteristics of indigenous Hair goat kids reared under an extensive production system. A total of 60 Hair goat kids (30 females and 30 males) slaughtered at 3, 6, 9 and 12 months of age was used as the material of this study. In the study, the cold carcass weights of kids at 3-12 months of age were between 6.15 and 10.83 kg. The cold dressing percentage was determined as 47.04-52.65 %. The effect of slaughter age on these traits was statistically significant (P<0.001). The cold carcass weight and the cold dressing percentage increased with the slaughter age. The effect of kid gender on the cold carcass weight was statistically significant (P<0.001). The mean value of this trait in males was higher than the females. The percentages of omental-mesenteric fat (P<0.001) and kidney-knob and channel fat (P<0.01) significantly increased with slaughter age. Subcutan, intermuscular, total fat and muscle/ bone percentages of the left half carcass significantly increased with slaughter age (P<0.01). However, bone (P<0.05) and muscle/total fat (P<0.01) percentages significantly decreased with slaughter age. The female kids had significantly higher values than males in terms of omental-mesenteric fat, kidney-knob and channel fat, subcutaneous, intermuscular and total carcass fat percentages (P<0.001). In conclusion, it is recommended that Hair goat kids should be slaughtered at 9 months of age under extensive management system to result in more edible meat production.

This study was undertaken to measure the effect of fattening duration (60, 80, and 100 days) on growth performance and carcass characteristics of male kids from indigenous Hair and Honamlı goat breeds reared under intensive fattening systems in Turkey. Fattening duration had a significant effect (P < 0.001) on the fattening performance and a number of carcass characteristics of kids. An interaction was detected between genotype and fattening duration for average daily gain (ADG). Hair goat kids grew at a faster rate than Honamlı kids in the 20-40 day and 40-60 day fattening periods, but they maintained relatively similar ADGs within other fattening periods. On average, over the course of the fattening trial, Honamlı kids grew at an average daily rate of 209 g/head, while Hair goat kids grew at a daily rate of 231 g/head. Dressing percentage and carcass lean and fat percentages of kids increased (P < 0.05-0.001) with slaughter age and weight for both genotypes, whereas the percentage of bone decreased (P < 0.001) with each successive fattening period. No genotypic differences were detected for a number of carcass characteristics at the time of slaughter, with the exception of relatively higher (P < 0.01) fat deposit rates within the kidney and pelvic areas for Hair kids.
Thirty two weaned (90 days) males (16) and females (16) native kids with an average live weight of 16.22±0.80 for males and 17.00 ±0.7 kg for females were used in this experiment. Each sex was divided randomly into two groups, the first (8 males and 8 females) was penned individually and fed on concentrate, and the second group (8 males and 8 females) was raised on pasture to be fattened and slaughtered at 20 kg or 30 kg. Result revealed that daily gain in weight averaged 75.65±5.54 g/day. No significant differences were observed due to the effect of sex, feeding system and slaughter weight on this trait. Male kids and those slaughtered at 30 kg were more efficient in converting feed than females and kids slaughtered at 20kg. Dressing percentage based on live weight and on empty body weight averaged 46.54 ±0.50 and 56.76 ± 0.44 %, respectively. Kids received concentrate and those slaughtered at 30 kg had significantly (p<0.05) higher dressing percentage than kids raised on pasture or slaughtered at 20kg. Kids slaughtered at 30kg had significantly (p<0.05) larger rib eye area and thicker fat than kids slaughtered at 20kg. Kids raised on pasture had significantly higher proportion of leg (31.8 vs. 29.98%) and lower proportion of shoulder (17.72vs. 19.92%) than kids received concentrate.
Relative growth of carcass tissues of goat kids from five breed Types finished on pasture or feedlot
Semina: Ciências Agrárias, 2016
The aim of this study was to evaluate the effect of cross breeding, finishing system, and gender on the relative growth of carcass tissues of dairy kids. Seventy eight kids (39 male and 39 female) from five breed types were used: Alpine; ½ Boer + ½ Alpine (½ BA); ½ Nubian + ½ Alpine (½ ANA); ¾ Boer + ¼ Alpine (¾ BA); and ½ Nubian + ¼ Boer + ¼ Alpine (TC). Kids were distributed into two finishing systems: in pasture with doe (FS1) and weaned in feedlot (FS2). Kids were slaughtered at a mean age of 128.4 ± 7.9 days and mean live weight of 22.07 kg. The mean weight of half carcasses was 5.09 kg. To determine allometric growth, we used the exponential equation Y= aXb. In the half carcass, muscle tissue showed comparatively early growth in group ½ BA, whereas fat tissue of animals in FS1 had relatively late growth. Females exhibited early growth of muscle tissue, while in males this tissue was intermediate. The ½ BA first-cross improved carcass characteristics by enhancing the growth of ...
Birth weights and growth performances of hair goat kids raised in Denizli Province of Turkey
The aim of this study was to determine birth weights and growth performances of hair goat kids till 5 months (150 days) of age at the extensive breeding conditions in Denizli province of Turkey. The analyzed data from hair goats in 54 breeders’ flock (4 multiplier and 50 base flocks) was collected in years 2011 and 2012. The least square means for kids’ birth weight were found as 3.29 kg.The differences created by flock type, birth type and sex, except years, on birth weight of kids were found statistically significant (P< 0.01).The least square means for live weight of kids at an average age of 150 days were 27.15 kg. This traits was significantly affected by sex (P< 0.05) and age of kids (P< 0.01) only. The average daily gain of kids for first five months of life was 156.32 g. Among the investigated factors, only the age of kids have a significant effect (P< 0.01) on average daily gains (ADG) of kids. The numbers of researches conducted on hairy goats are very limited....

Data of 198 male Creole kids were analysed to assess the main non-genetic sources of variation of their meat abilities. Basal diet was composed of tropical pasture (28 days): in FD (forage diet), kids received no supplement; in group MD (mixed diet) they were offered 360 g/day pellet, while in group PD (pasture diet) kids were reared at pasture without supplementation. Given a regular four-month interval of weaning within the flock, fixed ages at slaughter (AS) were 7, 11 and 15 months. Three slaughter weights (SW) were compared 17-18, 21-22 and 25-26 kg. The growth levels before weaning and the season of birth effects were added in the statistical analysis. The use of MD has a significant (P<0.05) effect on almost all the body and carcass traits: 85% more ADG and carcass weight. The weights of fat tissues increased but represented only 4% of empty body weight. As expected, there were significant (P< 0.05) differences within the SW and AS classes that are discussed. Range of variations allow for suggesting further experiments or practical recommendations. The initial results: carcass yield (55%), conformation score (more than 3), fat cover score (less than 3), proportion of primal cuts (63%) or muscle/bone ratio (3-4 points) are a good incentive for the local sector.

A total of 32 weaned (90 days) males (16) and females (16) native kids were randomly allocated into two equal groups to be fed either concentrate or to be raised on pasture, and then slaughtered at 20 or 30 kg live body weight. Animals were slaughtered when each kid reached its target body weight. After chilling at 4 C for 24h, the carcass was split along the vertebral column in to two halves. The muscular tissue of the left half- carcass was separated into nine groups. Carcass fat and bones was also, separated and weighed. Lean, fat, bone, lean: fat and lean: bone ratio averaged 64.08 ± 0.62%, 13.31±0.94%, 22.59±0.45%, 6.02 ± 0.58 and 2.98±0.09 respectively. Male kids had significantly (p<0.05) higher lean, lean: fat ratio and MG3 and MG4 than females. Kids raised on pasture had significantly (p<0.05) higher proportion of lean, bone and lean: fat ratio and lower proportion of MG3 than kids fed concentrate. Also, kids slaughtered at 30kg yielded significantly (p<0.05) lower...

The research aimed at analysing the slaughter value and physicochemical attributes of goat kids slaughtered at 90 and 180 days of age. After weaning at 60 days of age, a balanced mixture containing 18.2 % of protein and 5.63 MJ of net energy was applied as a feed. Some traits of live and slaughtered animal weight attributes were analysed. Moreover, tissue composition of the half carcass and meat physicochemical properties of meat were determined. The carcass of older male kid goats was by 5.08 kg (P≤0.05) heavier and the weight of primal cuts (P≤0.05) including high-priced cuts was by 0.87 kg higher than the young kids. Half carcass tissue composition of older and younger kids was similar: 60.13-60.50 % of meat, 25.48-25.37 % of bones, and 14.39-14.13 % of fat. Significant differences (P≤0.05) in fat and bone contents were only found in the leg. Furthermore, physiochemical properties indicated that the meat of older animals was darker and had higher values of chemical parameters.

To study the influence of castration and slaughter weight, 24 weaned kids from each of Black goat and Meriz kids were divided equally into two groups, the first was castrated, while the second was left intact, and all were fed individually and slaughtered at 15, 20 and 25kg. Results revealed that the overall mean of daily gain (DG), feed conversion ratio (FCR), Dressing percentage (DP), rib eye area (REA) and fat thickness (FT) averaged respectively 0.073±0.003kg, 6.062±0.32kg/kg, 41.17±0.35%, 10.05±0.40 cm2 and 0.33±0.04mm. It seems that breed had no significant effect on DG and DP. Black goat had significantly higher FCR, REA and FT than Meriz kids, and intact kids had significantly (P<0.05) higher DG and FCR than castrated only. A significant effect was noticed of slaughter weight on DG, FCR, REA and FT being highest in kids slaughtered at 25kg. A significant effect was observed for the effect of breed, castration and slaughter weight on some of muscle groups (MG1, MG3, MG4, MG5, MG6, MG7, MG9). Breed and castration had no effect on total carcass fat. Meriz kids had significantly(P<0.05) higher lean: fat ratio and lean: bone ratio.
