Lambing Preparation 2_default

Introduction

In this session, we will focus on the processes involved in lambing and the risks associated with lamb survival, highlighting the importance of interventions at the right time to reduce mortality.

Key Risks and Management Strategies

  • Dystocia: Managing dystocia effectively reduces the negative impact on lamb survival. Proper care during the lambing process minimizes trauma to both lamb and ewe.

  • Colostrum Quality: Poor quality or insufficient colostrum is a leading cause of lamb mortality. Ensuring adequate intake of high-quality colostrum within the first hours after birth is critical for the lamb's immunity and energy.

  • Environmental Factors: Poor hygiene, inadequate supervision, harsh weather conditions, and infectious diseases can dramatically affect lamb survival rates.

  • Body Condition and Birth Weight: Assess the body condition score (BCS) of the ewes and the birth weights of lambs to identify at-risk individuals. Low birth weights often indicate malnutrition in the ewe, while larger lambs may suffer from birth trauma.

Pre-Lambing Considerations

  • Lambing Environment: Ensure a clean, dry, and well-drained area for lambing. Adequate bedding and sanitation can prevent infections.

  • Identifying At-Risk Lambs: Monitor the body condition of the ewes and lamb birth weights. Ensure ewes are well-nourished and able to produce sufficient colostrum.

  • Intervention Awareness: Be prepared to identify lambs needing extra attention, particularly those birthed with assistance, low birth weights, or signs of distress.

Immediate Post-Birth Care

  1. Breathing Assessment: After ensuring the lamb is not in a birth sack, verify that it is breathing effectively. If it fails to breathe within a reasonable time, interventions like gentle stimulation or using respiratory stimulants should be employed.

  2. Administering Colostrum: Ensure lambs receive adequate colostrum within the first hours after birth, ideally from their own mother. If the ewe cannot provide sufficient colostrum, seek alternative sources.

  • Supplementing Colostrum: Encourage milking of the ewe for colostrum or utilize colostrum from other healthy ewes or cows when necessary. Commercial colostrum replacements should be used with caution, as they may not have the desired antibody profile.

  1. Navel Treatment: Disinfect the navel with a suitable iodine solution immediately after birth to prevent infections. This should be done multiple times as necessary to ensure proper healing.

Monitoring and Feeding

  • Observing Feeding Behavior: Watch for signs of successful suckling—lambs should be actively suckling from the ewe. If signs of colostrum deficiency are present, consider supplemental feeding options like stomach tubing to ensure intake.

  • Palpation Techniques: Feel the lamb's abdomen to check for a full stomach, confirming adequate colostrum consumption. Prompt action should be taken for those that appear underfed.

Common Post-Birth Problems

  • Hypothermia: Recognize the signs of hypothermia, especially in wet and cold conditions. Treatment involves drying the lamb and providing warmth, along with necessary colostrum intake to stabilize core body temperature.

  • Navel Ill and Joint Ill: Monitor for infections that can arise from poor navel hygiene. Treat naval infections with appropriate antibiotics if symptomatic signs appear, ensuring preventive measures are in place.

  • Watery Mouth (E. coli Infection): This condition typically arises from poor management practices regarding feed and hygiene. Preventative practices and timely interventions are crucial.

Conclusion

Maintaining hygienic practices, ensuring adequate nursing, and observing lambs carefully are paramount in reducing mortality rates during the lambing period. While most lambs will thrive with adequate care, the focus should always remain on identifying those requiring additional support.

Throughout the lambing season, enjoy the process, enhance your skills, and contribute to the welfare of the animals.
