And the dead were judged by what was written in the books, according to what they had done." Revelation adds, "And if anyone's name was not found written in the book of life, he was thrown into the lake of fire." Revelation then adds that the book of life belongs to the Lamb, Jesus Christ. Most lamb loss occurs in the first three days after birth so reducing lamb losses must focus on factors that can improve survival of new-born lambs. As the condition score of ewes at lambing increases, so does lamb survival, especially in twin bearing ewes.
Introduction: Colostrum is the first milk provided by the dam to her offspring. It is critical not only for the animal’s basic nutritional needs, but also for the newborn to be able to survive the multitude of environmental factors that may cause its death. Colostrum is rich in energy and has a mild laxative effect that helps to move the fetal feces (meconium) and to prevent the. Factors Affecting Calf Survival. R. A. Bellows. 1. USDA-ARS, Livestock and Range Research Laboratory Miles City, Montana INTRODUCTION Survival of the calf at or shortly after birth can be compromised leading to high death losses and a serious impact on net income for the cattle producer.

Factors affecting survival of lambs Single lambs Birth weight was the dominant characteristic influ encing survival of single lambs. In particular, the quadratic component of birth weight was signifi cant (P. Factors best explaining the probability of lambs falling into a death category included both birth type and birth weight for dystocia, stillbirth, starvation/mismothering and death in utero.
Lamb survival is one of the major factors affecting overall sheep flock productivity. Various studies have reported the results of analyses of survival data, and likely factors affecting survival, e.g., birth weight (BW), age of dam, breed of lamb, sire, and birth rank.
Among these studies, one of the first to. It was found that lambs with low birth weight had greater risk of Published: Novem Abstract The lamb mortality is critical component in sheep industry. The present study was carried out to determine the lamb mortality and its associated factors in Deccani sheep using survival analysis.
The data records of lambs reared at ICAR. This factsheet is one of a set of three, “Assisting the Ewe at Lambing”, “Care of the Newborn Lamb”, and “Treating Hypothermia (Chilling) and Hypoglycemia (Starvation) in Very Young Lambs”, concerning lamb survival.
They should be read together. The ewe’s gestation period is from to days, with an average of days. Litter size, lamb survival, birth and twelve week weight in lambs born to cross-bred ewes (B.C. Thomson et al) lower lambing percentage than the mixed age ewes (Table 1).

GROWING GREAT LAMBS. Improving newborn lamb survival The number of lambs reared per ewe is an important factor affecting the productivity of a sheep flock.
Results from the Hybu Cig Cymru (HCC) lambing survey, conducted on 70 flocks in Wales during the / breeding season demonstrated that 49% of total lamb losses occurred at lambing ( hours), 11 % at 2. Hypothermia in newborn lambs Hypothermia and starvation are the two principal causes of early lamb mortality.
To maintain its body temperature the newborn lamb must produce as much heat as it is losing to the environment.
If the lamb cannot do this, its body temperature will start to fall. The most important factors influencing lamb growth rates pre-weaning are likely to be improved milk production from lambing to weaning (higher pasture covers, better ewe condition at lambing, improved ewe genetics) and higher pasture quality in late lactation.
Feeding ewes during lactation. Parental care promotes offspring survival and, for livestock species, this care is provided solely by the mother. Maternal behaviour in the sheep has been exceptionally well-studied compared with other species and many of the underpinning biological processes leading to Cited by: The objectives of this study were to determine factors affecting lamb birth weight (BWT) and differences between BWT of the largest and smallest littermates (BWTD) and to assess the relative.
“Weak lambs” are lambs that just generally fail to thrive after birth. We’re talking about the first 48 hours here. They may be slow to get up, slow to nurse, or slow to start wobbling around with the rest of the lamb flock.
Additional Physical Format: Online version: Phillips, Ralph W., Some factors affecting survival, growth and selection of lambs. Washington, D.C.: U.S. Dept. The major factors affecting cold resistance are the breed and place of origin (mountain breeds performed best), birthweight (heavier lambs were more cold resistant), skinfold thickness (thicker skin conferred greater cold resis- tance), and metabolic rate capability during cold exposure (Samson and Slee, unpublished results).Cited by: In addition, further factors included in the analysis were health of the lamb (i.e.
did the lamb die within 3 days of birth) and whether a ewe was barren in any particular year. From the barren season history, we derived variates corresponding to (a) the present number of consecutive barren seasons and (b) the number of seasons since a ewe was last by: Lambs with the greatest risk of becoming hypothermic include: small and premature lambs, lambs which are weak and limp at birth, lambs from ewes in poor condition, lambs from very old or very young ewes, lambs born into a cold, wet, windy environment, twins and especially triplets The newborn lamb’s ability to produce heat is proportional to.
Non-genetic factors also have been reported to have effect on lamb survival such as the sex of lamb, litter size, age of dam, season and year of birth, birth weight, and body weight of the dam (Morris et al.,Mandal et al., ). Frequently, lamb survival is analyzed as a binary trait (Southey et al., ).
If the exact time of death or Cited by: 3. Factors best explaining the probability of lambs falling into a death category included both birth type and birthweight for dystocia, stillbirth, starvation–mismothering and death in utero –prematurity.
The probability of a lamb falling into any category was predicted at the mean birthweight, within birth by: Effects of nutrition on prenatal growth and the implications for perinatal survival in lambs.

This study examined the viability of 4, D’man lambs born alive at Errachidia research station in south-eastern Morocco between and Lamb survival to 1, 10, 30 and 90 days old was, andrespectively.
The majority of deaths ( %) occurred before 10 days of age.

To prevent hypothermia, make sure your lambs feed within the first few hours of life. You can buy a bit of time with heat lamps, but that time will be limited.
