Pengaruh perbedaan waktu inseminasi buatan terhadap keberhasilan kebuntingan sapi Brahman Cross
Abstract: The purpose of this
research is to acknowledge the difference of AI time towards Brahman Cross
Cow’s pregnancy rate determined by time and Non Return Rate (NRR). The subjects
in this research are 75 female Brahman Cross. Methods that were used during
this research are fiels testing. Selection method of the sample livestock used
is Purpose Sampling with criterias : Female adult cow with weight >250kg,
aged 1,5 – 2 years, healthy, and free from any disease, and at least have
mating urge. Materials used during this research are frozen cow semen that
acquired from Balai Inseminasi Buatan (BIB) Lembang, Bandung, West Java widh
35-40% motility. The variabels are Cow’s pregnancy and mating urge’s symptomps.
Data acquired duringthis reserch are analyzed descriptively and chi-square
tested. Supportive datas are food and valuefrom heat detector (HD). Research
result shows that Brahman Cross species which AI within 0-4 hours interval have
higher CR according to NRR1, which is 70%. Compared with the other breed that
AI within 8-12 hour interval, which had 37,14% CR value. According to
chi-square test, the difference of AI time of Brahman Cross are p<0.05 which
means that the difference of AI time of cow is affecting the pregnancy rate. It
is advised that AI is executed during 0-4 hour interval after showing mating
symptomps and further reviewed about the difference between AI execution time
of Brahman Cross and further observation of NRR2 until NRR3 and also Pregnancy
Test to know the pregnancy success rate
of Brahman Cross.
