Abstract

This study aims to determine the effect of supplementary feeding on the reproductive performance of beef cattle and calf birth weight. Additional feed is given to cows who are pregnant (8-9 months) and after giving birth for 3 months. Additional feed provided is a complete feed prepared from local feed ingredients. The objectives of this supplementary feeding are: maintaining the condition of the mother's body, maintaining normal embryo growth, and accelerating postpartum estrus, as has been done in Megal Village, Pamotan District, Rembang Regency. Provision of additional feed to old pregnant beef cattle (8-9 months) and after giving birth for 3 months in Megal Village, Pamotan District, Rembang Regency. The conclusion of this study is that the provision of additional feed 5 kg / head / day to old pregnant beef cattle and after giving birth for 3 months can reduce the weight loss of beef cattle broods when the availability of feed is limited, increase birth weight of calves and accelerate postpartum estrus. estrus for the first time after childbirth). Provision of additional feed to late pregnant beef cattle and after giving birth is highly recommended, especially in areas where the availability of feed fluctuates.Key words: supplementary feed, reproduction, beef cattle

Abstract

The research was conducted from 2016 to 2018 “on farm research” involving members of livestock farmer groups. Research material for intensively reared buffalo, belonging to membersof a livestock farmer group in Sidamulya Village, Warureja District, Tegal Regency. Observation begins with buffalo that will be selected as research material. The research material depends on the condition of the livestock owned by the breeder, especially the availability of livestock that are included in the research criteria, namely adult female cattle in physiological status for a period of 2-3 months postpartum unestrous. Therefore, the research material is not observed simultaneously. The material of 24 adult female buffaloes was allocated into two timeframes for IB implementation, namely 11 IB at approximately 18 hours after showing signs of lust and 13 tails in IB after 36 hours showing signs of lust. There is no special treatment for livestock material, such as estrus synchronization. The variables observed were the presence of signs of estrus, the number of cattle that had been in IB and the time of IB implementation. IB was carried out twice (two straws). Observations on livestock showing signs of estrus were focused on the morning. The results of Hafez's research, reported that buffaloes were in lust between 18.00 and 06.00. The data obtained from the observations were analyzed descriptively. The results showed that the IB time in buffaloes should be done 36 hours, compared to 18 hours after the signs of estrus were known (69.23% ; 30.77%).

Abstract

The research was conducted in 2018, in the dry land agro-ecosystem area, namely in Karangharjo Village, Sulang District, Rembang Regency. The aim of the study was to determine the reproductive picture (Service per conception S/C, post partus unestrus (APP), calving interval) of beef cattle in a traditional farming system at the level of smallholder farming. The research method uses descriptive methods and data obtained through surveys with interviews with 30 respondents and using a structured list of questions as a tool to collect the necessary data. The data obtained were then described and interpreted. The results showed that the breeds of cattle kept by breeders were the Ongole (PO) breeds and the breeds of Simmental and PO (Simpo) crosses. The average ownership of PO cattle is between 2-3 heads and the Simpo cattle breed is on average 1-2 heads. The forage provided from November to March was mostly grass and some superior grass, but the forage provided from April to October consisted of grass, sugarcane shoots and rice straw. Not all breeders provide additional feed in the form of rice bran to their livestock. There are differences in post partum unestrus (APP), service per conception and calving interval between cattle fed with supplementary feed and without additional feed, both PO and Simpo cattle. However, there was no difference between PO cattle and the age at first mating, as well as between Simpo cattle, but the first mating age for PO cattle was faster than Simpo cattle.Keywords: Beef cattle, feed and reproduction
