Abstract:ln this research, the characteristics with some reproductive traits, managements of milking and shearing period and problems appearing in rearing of the Hair goat farms in district of Centre, Korkuteli, Elmal ı , Kaş, Manavgat, Gündoğmuş and Gazipaşa in the Antalya province were researched. Acorrding to f ındings of research, it was founded that first breeding age and duration of breeding for male and female goats were 1.7±0.14; 2.0±0.16 years and 5.1±0.38; 6.38±0.42 years, respectively. The weainig age and milking duration were 2.5±0.25 and 3.8±0.51 mounth, respectively. The first shearing age was 1.3± 0.09 year and shearing mainly was carried out on August.

Scanning electron microscopy and morphometric analysis of the hair in dromedaries with SEM-EDX in relation to age

“…In our study, the one-humped camel hair medulla had a variety of patterns and structures, including a continuous pattern and an amorphous structure (75%, 70%, and 90% in the G1, G2, and G3 groups, respectively), as well as interrupted intruding amorphous, interrupted, vacuolated, or amorphous medulla and fragmented amorphous medulla (25%, 30%, and 10% in the G1, G2, and G3 groups, respectively). Previous research has shown that the medulla of Maghrebi camel hair fibers was 50% continuous, 38% fragmented, and 12% interrupted [ 45 ]. The adult male one-humped camel’s cortex was pigmented, and the medulla had a continuous, smooth margin [ 13 ] and camel hair is divided into two parts: thin, non-medullated, or medullated hair fibers and thick, interrupted, or continuous medulla hair fibers [ 24 ].…”

“…The medullary index in camels is also varied; in Bactrian camels, the medullary index was less than 1/4 of the hair diameter (16.63 to 16.86 μm), whereas, in the Llama, the medullary index was about 1/3 of the hair diameter, ranging from 33.33 μm to 33.96 μm [ 50 ]. Camel hair had a medullary index percentage of approximately 78.66% [ 45 ]. The medulla within adult male dromedary camels was found to be more than half the diameter of their hair [ 13 ].…”

Some Feedlots Do Not Change Biochemical and Wool Mineral Profile in Dromedary Calves

“…The reported concentrations of calcium, magnesium, copper, zinc, iron and manganese were 549.6±74. Helal (2015) who reported higher concentrations of B, Cd, Co, Cr, Fe, Mn, Ni and S in fine hairs of Maghrebi camels while Mo, Pb and Zn were higher in coarse fibers. Furthermore, the similar studies done on horses (Or et al, 2004) and yaks (Chattergee et al, 2005) revealed that level of some mineral elements were affected by nutritional differences.…”

Effect of Wool Handle Grade of Barki Sheep Wool on Its Manufacturing Characteristics

“…Yarn elongation of control wool grade had the highest value followed by soft and medium wool grades, respectively and the lowest value of yarn elongation was that of harsh wool grade. Helal et al (2008) reported that yarn elongation tended to increase with the increase of fineness, which might be related to the increase in fiber crimps. For plied yarn, sorting system significantly (P< 0.05) affected yarn count and significantly (P< 0.01) affected yarn strength, tenacity and twisting (Table 5).…”

“…), respectively and the lowest was that of control wool grade (893.90 ±29.5 gf.). Helal et al (2008) reported that yarn tenacity tended to decrease with the increase in fiber diameter and staple length. The increase in yarn strength may be due to the increase of numbers of fibers in the yarn cross section.…”
