“…The average body weight of the kids slaughtered was similar to the results obtained in earlier studies by the authors (PIENIAK-LENDZION et al 2005) and the research results, concerning different period of goat kid slaughter, by other researchers (SEN et al 2004, STANISZ and GUT 2005, KOYUNCU et al 2007). In the studies carried out on 5-month goat kids with the Boer breed genes, STANISZ and GUT (2005) (20.16-22.74 %) in legs of castrated kids in relation to the breed than in the presented study.…”

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. Keywords

“…The bone (9.56 vs. 7.09 %) and muscle (52.05 vs. 56.50 %) contents of carcasses differed significantly between intact males and castrated (KOYUNCU et al 2007). The content of culinary meat in the leg was similar to the values obtained by KĘDZIOR et al (1997) as well as earlier studies by PIENIAK-LENDZION et al (2003).…”

“…The effect of castration on average daily weight gain in goats has not been consistent. Daily weight gains of castrated goats were either lower (Allan and Holst, 1989), higher (Mackenzie, 1970) or unchanged (Koyuncu et al, 2007), compared to intact goats.…”

Castration has been shown to elicit physiological stress, inflammatory reactions, pain-associated behaviour, suppression of immune function, and a reduction in performance to varying degrees. The responses to castration using Burdizzo were investigated in four male West African Dwarf (WAD) goats hourly over a period of 3 hours. The bucks were castrated with Burdizzo clamp, blood samples were collected by jugular venipuncture for biochemical, hematological and hormonal analyses. The hematological values showed significant decreases (P<0.05) in PCV, Hb, Rbc, neutrophil throughout the period, while the White blood cell count decreased significantly 1 hour post castration. Respiratory rate increased significantly (P<0.05) throughout the post castration period of study, while the rectal temperature significantly increasing (P<0.05) for just an hour post castration. Cortisol level rose significantly (P<0.05) throughout the study period. Testosterone and estrogen levels fell after an hour though non-significantly (P>0.05) but later rose significantly (P<0.05) during the second and third hour post castration. The serum biochemistry changes observed include a significant rise (P<0.05) in AST, ALT, urea and Creatinine after 1 hour upon castration, but the values later significantly decreased (P<0.05) after the 2nd and 3rd hours. The serum electrolytes increased significantly (P<0.05) an hour post castration when compared with the pre castration values and later decreased significantly (P<0.05) at the 2nd and 3 hours post castration in comparison to the 1st hour value. There was a non-significant (P>0.05) increase in heart rate 1 hour post castration before returning to the pre castration value. This study concluded that the effects of three hours post burdizzo castration on hematological and biochemical profile fluctuated significantly in all the values under study and this calls for clinical surveillance among surgeons when such animals are brought for surgery during the acute period of castration. Also, this study will make information available for clinicians and researchers.

INTISARIPenelitian ini bertujuan untuk mengetahui pengaruh berat potong dan harga pembelian domba dan kambing terhadap gross margin jagal di RPH Mentik Kresen Bantul. Penelitian dilaksanakan dengan obyek penelitian aktivitas produksi jagal domba dan kambing lokal betina. Sampel yang digunakan adalah ternak domba dan kambing betina lokal masing-masing 60 ekor. Sampel dibagi masing-masing 30 ekor dalam berat potong 10 sampai14,99 kg (BP 1 ) dan berat potong 15 sampai 20 kg (BP 2 ). Data yang diambil adalah harga beli, berat potong, biaya variabel, produksi karkasnonkarkas dan gross margin jagal. Uji faktorial digunakan untuk mengetahui perbedaan antara jenis ternak dan kelompok berat hidup mana yang paling baik untuk produksi per ekor domba dan kambing. Analisis regresi linier berganda untuk mengetahui pengaruh harga beli dan berat potong terhadap produksi domba dan kambing, serta berat potong dan biaya variabel terhadap gross margin jagal domba dan kambing. Hasil penelitian menunjukkan kambing Bligon betina dengan berat potong 15-20 kg menghasilkan produksi dan gross margin yang paling tinggi yaitu sebesar 9,83 kg dan Rp. 104.901,50. Harga beli dan berat potong secara signifikan dan positif berpengaruh terhadap produksi domba dan kambing lokal betina dengan R 2 =0,718. Terdapat perbedaan produksi pada domba dan kambing. Produksi kambing lebih baik dari produksi domba. Berat potong secara signifikan dan positif berpengaruh terhadap gross margin jagal. Biaya variabel secara signifikan dan negatif berpengaruh terhadap gross margin jagal dengan R 2 =0,665. Semakin tinggi biaya variabel akan menurunkan gross margin jagal. Terdapat perbedaan gross margin domba dan kambing. Gross margin kambing lebih baik dari gross margin domba. Berdasarkan hasil penelitian dapat disimpulkan bahwa produksi dan gross margin kambing betina lebih baik dari domba betina.(Kata kunci: Domba dan kambing lokal betina, Persentase karkas dan nonkarkas, Produksi, Gross margin) ABSTRACT This study was aimed to determine the effect of slaughter weight and purchasing price of female sheep and goats on the butcher's gross margins at the slaughterhouse of Mentik
