Abstract
Evaluation of Relationships Between Some Growth Traits Measured at Birth and Weaning in South African Non-Descript Goat Kids using Canonical Correlation Analysis
Highlights
South African non-descript goats are important to the communal farmers as they provide income and demand less capital for treatments and feed-supplement as they are hardy, resistant to diseases, good forager, well adapted to the harsh environment and fertile from a young age (Tyasi et al, 2020; Norris et al.,2015)
A weighing scale was used to measure Body Weight (BW) while growth traits, namely Body Length (BL), Sternum Height (SH), Heart Girth (HG), withers height (WH) and Rump Height (RH) were measured at birth and weaning using a tape and a wooden ruler calibrated in centimetres
The descriptive statistics for the examined traits at birth and weaning are shown in Table 1 while Table 2 shows a correlation among growth traits
Summary
South African non-descript goats are important to the communal farmers as they provide income and demand less capital for treatments and feed-supplement as they are hardy, resistant to diseases, good forager, well adapted to the harsh environment and fertile from a young age (Tyasi et al, 2020; Norris et al.,2015). The canonical correlation has been used to describe the relationship among birth weight and weaning weight in German sheep breeds (Çankaya and Kaylaap, 2007), reproduction and production traits of meat-type quails (Ribeiro et al, 2016), milk and wool yield in Akkaraman sheep in previous livestock studies (Karadavut, 2020). The objectives of the paper were to (1) investigate the interrelationship between the six different body measurement traits at birth and weaning; (2) to explore which traits might be used at birth as selection criteria to improve the live body weight of non-descript goats at birth and weaning. This study will assist small stock farmers to identify interrelation among growth traits and making a good decision when selecting traits to improve the live body weight at birth and weaning
