The Effect of Marriage Frequency and Sex Ratio on Litter Size, Birth Weights, Mortality while Breastfeed, and Weaning Weight on Rabbits Crossing

Introduction

Rabbit breeding is an important industry that provides a source of income for many farmers around the world. However, the success of rabbit breeding depends on several factors, including the frequency of marriage and sex ratio. The frequency of marriage refers to the number of times a female rabbit is mated with a male rabbit, while the sex ratio refers to the number of females to males in a breeding group. In this study, we investigated the effect of marriage frequency and sex ratio on litter size, birth weights, mortality while breastfeeding, and weaning weight on rabbits crossing.

Methodology

This study was conducted on a farm owned by Mr. Jamin Purba SPT in Gang Rukun, Karo Regency, from June 5 to August 31, 2007. The study used a complete factorial (RAL) complete random design. The first factor was the frequency of marriage with four levels: F1 = one mating, F2 = two marriages, F3 = three marriages, and F4 = four marriages. The second factor was the sex ratio with three levels: B1 = 2 females: 1 male, B2 = 4 females: 1 male, and B3 = 6 females: 1 male.

Results

The results of this study showed that the average litter size (number of children) was 6.88, with the highest value in the F1B3 treatment which was 8.00 and the lowest in F1B1 was 6.17. The average birth weight (gram/child) was 50.13, with the highest value at F1B3 which was 55.80 grams/child and the lowest in F3B1 was 45.27 grams/child. The average mortality during breastfeeding (%) was 11.90, with the highest value in F3B2 which was 22.02% and the lowest in F1B1 was 6.25%. The average weaning weight (gram/child) was 311.59, with the highest value on F1B1 which was 366.45 grams/child and the lowest in F3B1 was 269.27 grams/child.

Discussion

The results of this study indicate that the effect of marriage frequency, sex ratio, and interaction between the two factors do not have a significant effect on the size of the litter, birth weight, mortality while breastfeeding, and weaning weight in crossing rabbits. This suggests that the frequency of marriage and sex ratio, in the range under study, do not have a significant impact on the characteristics of the production of rabbit crossing.

Deeper Analysis

The results of this study can be interpreted as follows:

  • Marriage Frequency: Although this study involved up to four marriages, no significant differences were found in production results. This may be caused by other factors that affect the results of production, such as the quality of feed, cage management, and genetics.
  • Sex Ratio: The ratio of sex varies in this study does not show a significant difference in the size of the litter, birth weight, mortality, and wean weight. This can indicate that crossing rabbits have a good adaptability to different sex ratios.

Implications for Breeders

The results of this study provide several implications for rabbit breeders:

  • Management Optimization: Farmers can focus on other factors that have proven to affect the results of production, such as the quality of feed, cage management, and disease control.
  • Reproductive Efficiency: Farmers can choose the frequency of marriage that suits their needs, without worrying about a significant impact on production results.
  • Selection of Gender Ratio: Breeders can choose the most practical and efficient sex ratio for them, without being fixed on the ideal ratio.

Further Research

This study opens opportunities for further research on the effect of marriage frequency and sex ratio on cross rabbits. Further research can be done by:

  • Examining a broader range of marriage frequencies: This research only examines the frequency of marriages up to four times. Further research can be done by examining the higher marriage frequency, for example up to five or six times, to see whether there is a significant effect on production results.
  • Examine the effect of more extreme sex ratios: This study only examines the ratio of gender up to 6 females: 1 male. Further research can be carried out by examining more extreme sex ratios, for example 8 females: 1 male or 10 females: 1 male, to see whether there is a significant effect on production results.
  • Examining the effect of other factors: This research only examines the effect of marriage frequency and sex ratio. Further research can be done by examining the influence of other factors that might affect production results, such as feed quality, cage management, and genetics.

A more comprehensive research will provide a better understanding of the effect of marriage frequency and sex ratio on rabbits crossing and helping farmers to increase their production.

Conclusion

In conclusion, this study investigated the effect of marriage frequency and sex ratio on litter size, birth weights, mortality while breastfeeding, and weaning weight on rabbits crossing. The results of this study indicate that the effect of marriage frequency, sex ratio, and interaction between the two factors do not have a significant effect on the size of the litter, birth weight, mortality while breastfeeding, and weaning weight in crossing rabbits. This study provides several implications for rabbit breeders and opens opportunities for further research on the effect of marriage frequency and sex ratio on cross rabbits.
