Some production traits and phenotypic relationships betweenudder and production traits of Hair goats

Abstract

The study was conducted to determine the production characteristics and to find out the phenotypic relationships between udder and milk production traits in Hair goats. A total of 403 Hair Goats under extensive conditions of Çine town of Aydin province of Turkey were constituted the animal material of the study. The live weights of all goats were recorded just before breeding season. Milk was measured in every month according to the basis of morning or evening milking in a day to estimation of milk yields. Live weights of kids were recorded monthly intervals. Measurements for udder characteristics were determined for two times at 30th and at 180th of the lactation period. Average lactation length, lactation milk yield and daily milk yield of goats were 192.4 days, 139.1 kg and 0.7 kg, respectively. The live weights at birth, 30th, 60th, 90th and 120th days of goat kids were 3.1, 8.6, 13.9, 19.1 and 24.5 kg, respectively. Mean values of withers height, body length and live weight of goats were measured as 73.2 cm, 71.3 cm and 54.5 kg, respectively. Udder and teat characteristics of goats were found positively correlated with milk production characteristics both 30th and 180th days of the lactation period. It can be concluded that Hair goats in extensive conditions had a substantial level of milk yield and their kids had sufficient levels of live weight gains. Furthermore, the udder measurements at the beginning of the lactation could be used for identifying the differences among does.

Effect of genotype and non-genetic factors on growth traits and survival rates in Turkish indigenous Hair goats and their first cross with Boer bucks

“…64, 8.89, 13.99, 18.97, 23.62, 27.22 and 30.44 kg at birth and at days 30, 60, 90, 120, 150, 180, respectively; and the ADGs were 171.09, 136.43 and 148.34 g in the pre-weaning, post-weaning and overall periods, respectively. These results were compared with previous studies conducted on HGs, and it was determined that these values were higher than those reported by Gökdal et al (2013), and similar to those reported by Cemal et al, (2013) and Atay and Gokdal (2016). The reasons for these variations may be the regions where the goats were breeding, the climatic and breeding conditions, and differences in genotype.…”

“…The goats are raised in intensive, semi-intensive and/or extensive management conditions, involving varying combinations of grazing, stall-feeding and housing, according to the season, geographical region, farm and climate. The main income for HG breeders in the country comes from sales of male kids of approximately 5-8 months-of-age (Atay and Gokdal, 2016).…”

Non Genetec Parameters and Repeatability for Milk Traits Goat in Northern Iraq

“…This because of the size of udder is larger of surrounding, teat distance, the length and the width (Alkass and Merkhan 2011). Such results resemble to earlier investigators who reported significant effect of doe's age on ADMY, MYAW and TMY (Alkass and Merkhan, 2011;Ibnelbachyr et al, 2015;AL -Dabbagh andOramari, 2016 andAtay andGokdal, 2016). While Hermiz et al (1998Hermiz et al ( , 2004Hermiz et al ( and 2015 didn't reveal to the significant effects for age of doe on their milk production.…”

Relationship between muscle fiber characteristics and meat quality parameters in Turkish native goat breeds

“…The most commonly raised native goat breeds in Turkey are Hair, Kilis, Angora and Honamli. Hair goat constitutes approximately 92% of the goat population in the country (Atay and Gokdal, 2016). Numerous studies have examined the muscle fiber characteristics and meat quality of sheep, cattle and pig.…”
