First … WHY?
Labor demands and feed requirements at birthing are cited by sheep and goat farmers as a major reason for why they do not expand or why they consider retirement
Can we reduce labor inputs and feed costs at lambing/kidding without adversely affecting kid and lamb mortality and herd productivity?
How much does labor affect kid/lamb mortality? • In Winter ’09 – some of our case study farms worked an extra 12 to 15 hrs/day during birthing as compared to as low as 2 hrs/day for other farms with similar herd sizes, productivity and mortality rates
Neonatal mortality is greatly affected by: • Your herd’s preventative health management program • Your herd’s nutritional program • How adequate your facilities are for the season of the year your animals give birth in • Litter size and season of birthing • Luck – and being able to find a quick fix
Outbreaks of disease or metabolic disorders can contribute substantially to neonatal mortality regardless of how much labor you put into the birthing season
Ways to keep labor and operating costs down • Winter/Early Spring • Late Spring/Summer • Fall
Birthing checks • Are you on the farm a lot? • Are the animals in easy view? • Are your facilities adequate for the season? • Have you culled does/ewes with dystocia problems? • Have you addressed management problems that led to dystocia or weak newborns?
Winter • Heat? • Safety • Type • Cost • Ventilation
“Juggling” sheep/goats around • What is your animal flow from Birthing • Jugs? • Mother/offspring areas
Grafting newborns - Is it an option? When successful – Greatly reduces or even eliminates need for artificial rearing Improves animal performance and ultimate welfare Reduces labor inputs during birth period
Grafting Protocol Overview • Must be very aware of livestock needs and opportunities. • Using techniques that concentrate birth period (i.e. ram/buck effect, concentrated male to female ratio) will allow more matching opportunities. • Assess these variables in making match • Milk supply • Milk requirement • Maternal bond • Newborn suckling drive
Grafting Protocol • Maintain graftee “natural” suckling drive by stomach tube feeding (24-48 h limit) • Maternal bond develops quickly (less than 5 min) but this is highly variable-need to assess each situation • Assess milk supply and use this info to determine which newborns to remove and which graftees to bring. • Possible to swap or mix entire litters if done before bonding is set. • Possible to graft in pasture birth. f
Techniques to facilitate bonding • Simulate birth process with hand in birth canal (use plastic ob sleeve). • Place fetal fluids from maternal litter on graftee. • When grafting into established litters or refining matches, place newborn feces from maternal litter on graftee. • Use head gate or halter to restrain mother if bonding is already established. Grafting success will be apparent within 48 h.
