The growth traits help rural farmers who lack weighing equipment to anticipate the body weights of their animals for a variety of reasons, including feeding, medication, and breeding purposes. The study aims to predict body weights from the growth traits of Doper sheep. Data on growth traits such as body length, heart girth, sternum height, withers height, rump height, and body weight were collected for one day from 50 Dorper sheep aged 1 to 2 years. Pearson's correlation and simple linear regression analysis were used to achieve the study's objectives. Pearson's correlation results in ewes indicated that body weights had a positive significant relationship with heart girth, wither height, and body length. Whereas in rams, body weights showed to be positively and statistically correlated to withers and sternum height. Simple linear regression demonstrated the highest coefficient with the lowest mean square error on heart girth in ewes and sternum and withers height in rams. Correlations suggest that increasing heart girth, withers height, and body length in ewes and withers and sternum height in rams might cause body weights to increase. The regression analysis in ewes revealed that heart girth contributes 27% of the variation in body weights, whereas sternum or withers height contributes 61% of the variation in rams. In conclusion, to improve body weights, ewes' heart girth, withers height, body length, and rams' withers and sternum heights and heart girth, may be selected.
The association between body measurements and udder measurements can be used towards the improvement of milk yield. The objective of the study was to investigate the correlation between udder measurement traits and milk yield. The study was conducted at Sikline village in Mankweng, Capricorn district of Limpopo province, South Africa where a total number of 30 lactating Saanen goats were used. Pearson’s correlation technique was used for data analysis. The results showed a significant (P<0.05) correlation between distance between teats and milk yield (r= 0.45) and a highly negative significant (P˂0.01) correlation between teat diameter and milk yield (r= -0.57). Body weight and milk yield (r= 0.54) had a highly positive significant correlation (P˂0.01). The finding of the current study implies that body weight and distance between teats can be used to improve the milk yield in Saanen goats. The finding of the study might be used to predict the milk yield of Saanen goats. However, further studies need to be conducted on relation of body and udder measurements and milk yield using higher sample size.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
