Partial diallel cross for assessing genetic merit of local rabbit breed

[EN] This study was carried out to estimate general combining ability (GCA) and specific combining ability (SCA) of pre-and post-weaning traits from a partial diallel cross in three rabbit breeds: Local rabbit (L), Flemish Giant (F), and Rex (R). Body weight at 0 (BW0), 30 (BW30), 42 (BW42), and 63 (BW63) days of age, average daily gains from 0 to 30 d of age (ADG0-30), from 30 to 42 d of age (ADG30-42), from 42 to 63 d of age (ADG42-63), and from 30 to 63 d of age (ADG30-63), litter size at birth (LS0) and at weaning (LS42), and mortality at weaning (MR42) were studied in crossing LL, FF, RR, LF, LR, and FR. Local breed had the highest GCA for BW0, BW30, BW42, and average daily gain before weaning (ADG0-30, and ADG30-42) compared to Flemish Giant and Rex, while GCA of Local breed for average daily gain after weaning (ADG42-63), litter size (LS0, and LS42), and mortality (MR42) was higher than for Rex and similar to that of Flemish Giant. Crossing LF and LR showed higher SCA for BW30, BW42, BW63, ADG0-30, ADG42-63 and ADG30-63 than FR. In conclusion, based on GCA and SCA, the Indonesian Local breed has a high genetic potential in the crossing with Flemish Giant and Rex breeds.This research was funded by Hibah Dana Penelitian Universitas Diponegoro Semarang with Contract No. 36/UN7.5.5.2/PP/2021Setiaji, A.; Kurnianto, E.; Sutopo, S.

Estimation of Genetic Superiority and Reproductive Performance of Dairy Cows at different rearing locations

The objective of this study was to estimate the genetic superiority using the estimated breeding value (EBV) and most probable producing ability (MPPA) and to elucidate the reproductive performance of dairy cows at two different rearing locations. This study used data from dairy cows in two areas, namely at the dairy breeding center (Group I) for 100 heads and the dairy farmers (group II) for 40 head cows. The survey method was used in this study. The parameters observed were total milk production, days open (DO), service per conception (S/C), and calving interval (CI). The data were analyzed descriptively and using a t-test. The results showed that productivity in groups I and II for the total milk production was 5,017.52±1,096.84 and 3,922.52±1,296.55 kg/head/lactation, respectively; DO was 141.45±64.30 and 281.68±92.42 days, respectively; S/C was 1.47±0.61 and 1.70±0.69 times, respectively; and CI was 421.59±63.47 and 565.23±95.33 days, respectively. In conclusion, differences in management systems in breeding center and dairy farmers group give different productivity. The results can be used for management improvement and increasing productivity strategies. Livestock selection in dairy breeding center and dairy farmers can be made by estimating the genetic superiority using the estimated breeding value and most probable producing ability

Effect of Age at First Calving on Milk Production and Reproductive Performance of Indonesian Holstein Dairy Cattle

The purpose of this study was to determine the milk production and reproductive performance of dairy cattle in groups of different ages at first calving and to elucidate the effect of age at first calving on milk production and calving interval of Indonesian Holstein dairy cattle. The observation method use in this study. Records of 80 dairy cows which were born in Indonesia and had the age at first calving range of 23-32 months were used as the materials. Cows were divided into two groups based on age at first calving (AFC). Group I was cows with age at first calving of 23-27 months and group II with age at first calving of 28-32 months. The parameters observed were the total milk yield, calving interval, post-partum mating, interval from calving to conception, and service per conception. To compare data between two groups, the t-tests and descriptive analysis were used. The results showed that the total milk yield, calving interval, postpartum mating, interval from calving to conception, and service per conception in the group I did not have a significant difference from the group II. The linear regression analysis showed that the age at first calving had a weak negative effect on the total milk yield, and the age at first calving had a weak positive effect on the calving interval. In conclusion, the difference in the age at first calving did not provide a different performance on milk production and reproduction of dairy cattl
