Abstract:
Cases of clinical reproduction in crossbred cattle have been reported with the
incidence of decreased reproductive performance. Crossbreeding resistance is
usually followed by low immunity. Blood profile is one of the parameters that
illustrate the immunity of livestocks. Goat crossbreeding resistance has never
been studied. The purpose of this study was to analyze the crossbreeding
resistance of the F1 BoerPE goat and her mothers by analyzing their blood
profile. F1 BoerPE goat is the offspring of crossbreeding between Boer buck with
PE goat. The research method was case study. The primary data were obtained
from examination of blood profile and Physiological Status of F1 BoerPE goat
and her mothers. The secondary data obtained from recording age and body
weight. The blood profile data were analyzed by t test. The observed blood
profile indicators were neutrophils, monocytes and lymphocytes. The results
showed that the physiological status of F1 BoerPE goat and her mothers was not
significant. Nevertheless, the number of neutrophils, lymphocytes and
monocytes was significantly different (p˂0.01). The average (%) number of
neutrophils, lymphocytes and monocytes of PE goats was 37.92 ± 1.37; 51.85 ±
1.4; 3.87 ± 0.21. while the average blood profile of F1 BoerPE was 46.16 ± 2.1;
58.06 ± 3.4; 5.51 ± 0.18. The average number of neutrophils, lymphocytes and
monocytes F1 BoerPE goat was higher compared to the parent. It is indicated
that there were crossbreeding resistance of F1 BoerPE goat.
