The estimation of the milk yield of a ewe from body weight data on the suckling lamb
TLDR
In this article, the role of the prediction equation in estimating daily milk consumption of lambs is discussed and the regression equation is used to estimate the milk consumption over the range of lamb body weights and lamb body-weight changes studied.Abstract:
Milk yield data obtained by the lamb-suckling technique on twenty-four ewes over a period of 5 consecutive days in the second and third week of their lactation have been related to lamb body weights and lamb body-weight changes over the same period. The regression equation obtained wasThe equation was used to estimate the milk consumption of lambs over the range of lamb body weights and lamb body-weight changes studied. The standard errors of these estimates have been computed for comparison with those obtained directly from the lamb suckling technique.The role of the prediction equation in estimating daily milk consumption of lambs is discussed.read more

Can an increased intake of metabolizable protein affect the periparturient relaxation in immunity against teladorsagia circumcincta in sheep
TL;DR: It is concluded that an increased intake of MP could enhance the expression of immunity to T. circumcincta of twin-bearing and -rearing Greyface ewes.

Effects of body fatness at lambing and diet in lactation on body tissue loss, feed intake and milk yield of ewes in early lactation
TL;DR: Twenty-six mature Finnish Landrace × Dorset Horn ewes, each suckling two lambs, were used in a comparative slaughter experiment to measure changes in body tissues during early lactation and there appeared to be a reduction in the energetic efficiency of milk synthesis.

Clinical findings in sheep farms affected by recurrent bacterial mastitis
TL;DR: Upon investigation of correlations existing among clinical signs and bacterial species responsible for the outbreak, S. uberis showed a statistically significant correlation with serous appearance of milk, presence of clots in secretions, and reactivity of supramammary lymph nodes.

Is the allocation of metabolisable protein prioritised to milk production rather than to immune functions in Teladorsagia circumcincta-infected lactating ewes?
TL;DR: The results support the view that the priority of scarce metabolisable protein allocation to milk production over immune functions may be gradual rather than absolute and points towards the possibility that if different effector responses regulate fecundity and worm expulsion, then they would differ in their sensitivity towards changes in the degree of nutrient scarcity.

Effects of protein supply and reproductive status on local and systemic immune responses to Teladorsagia circumcincta in sheep.
TL;DR: The data support the view that increased globule leukocyte counts and plasma IgE anti-L3 antibody may be associated with nutritionally improved expression of immunity in periparturient ewes, and suggest that changes in mucosal mast cell and eosinophil counts are not necessarily associated with changes in host resistance to T. circumcincta.

The growth of lambs before and after birth in relation to the level of nutrition.
TL;DR: In following the live-weight growth curves of the ewes it was found that on a constant level of feeding the weight gains became greater during each succeeding month of pregnancy, and at corresponding stages were larger for ditocous than for monotocous eWes.

Temperature regulation in the new-born lamb. V. Summit metabolism
TL;DR: Heavy lambs are able to maintain homeothermy under conditions of higher heat loss than light lambs, and summit metabolism in young lambs was approximately constant at all body weights, and hence summit metabolism per unit of surface area increased with increasing body weight.

A study of the lactation and growth of hill sheep in their native environment and under lowland conditions
TL;DR: It seems that milk yield has a fairly high repeatability and heritability, and a close but diminishing relationship is shown to exist between the milk yield of the ewe and the growth of the lamb.

A study of milk production of the grazing ewe, with emphasis on the experimental technique employed.
TL;DR: The oxytocin technique gave significantly higher figures for milk production than did the lamb-suckling technique, and this persisted throughout lactation, and correlation coefficients between lamb growth rate and milk yield of the ewe, measured by either technique, were high up to 7 weeks of age.
