TLDR
It is concluded that the technique merits further consideration, and that, with more precise knowledge of FFA concentrations in maintenance-fed sheep and of the FFA: food intake response curve, it could provide a useful alternative means of estimating maintenance requirements.Abstract:
The objective of the investigations reported in this paper was to examine the possibility of using plasma free fatty acid concentrations as a means of estimating food requirements for maintenance purposes in sheep. Estimates derived in these investigations are considered to be less satisfactory than those based on live-weight change. It is concluded, however, that the technique merits further consideration, and that, with more precise knowledge of FFA concentrations in maintenance-fed sheep and of the FFA: food intake response curve, it could provide a useful alternative means of estimating maintenance requirements.read more

Lipid metabolism in the adipose tissue of ruminant animals
TL;DR: This chapter discusses lipid metabolism in the adipose tissue of ruminant animals, which has a critical role as an energy source during lactation in high milk-yielding cows, but is also implicated in the depression in the yield of milk fat found in animals fed high-concentrate diets.

Polyphenolic Transmission to Segureño Lamb Meat from Ewesʼ Diet Supplemented with the Distillate from Rosemary (Rosmarinus officinalis) Leaves
TL;DR: It can be concluded that the incorporation of distilled rosemary leaves at a rate of 10% of the ewes' diet should be enough to improve the lamb meat antioxidant status.

Carbohydrate and Lipid Metabolism

TL;DR: The values in Table 1 were selected because fairly large numbers of animals were used (20) or measurements were made at intervals over two years (59), and the values shown in Table 2 are from sheep designated as fed as mentioned in this paper.

Plasma non-esterified fatty acids in sheep.
TL;DR: The results suggest that in sheep, as in many other species, NEBA are of major metabolic importance.

The use of biochemical parameters in controlling nutritional state in pregnant ewes, and the effect of undernourishment during pregnancy on lamb birth-weight
TL;DR: Undernourishment during the latter half of pregnancy reduced birth weights of single and twin lambs after adjustment for weight of the dams to the same extent and in the moderately undernourished ewes the reduction was approximately 10%, and, in the severely undernouredished eWes, approximately 25%.

Plasma non-esterified fatty acids in sheep
TL;DR: In this article, the concentration of plasma non-esterified fatty acids (NEFA) in sheep was found to be within the range 0.1-0.9 m-equiv/l.

Some Observations on the Estimation of non-Esterified Fatty Acid Concentrations in Cow and Sheep Plasma
TL;DR: In this article, a method for the estimation of the non-esterified fatty acid (NEFA) content of ruminant plasma has been described and the value of this parameter assessed as a measure of the rate of depot fat mobilization.

Studies on the carbohydrate metabolism of sheep. XVIII. The metabolism of glucose, free fatty acids, ketones, and amino acids in late pregnancy and lactation
TL;DR: Caloric homeostasis was best maintained in fat ewes fed ad libitum; variation in blood glucose and FFA levels during late pregnancy and early lactation was minimal, in spite of a marked and variable decline in feed intake in twin-bearing eWes in late pregnancy.
