The aim of this study was to investigate the effect of two species of the microalgae on the milk yield, the basic composition and the fatty acid profile of goat milk, with focus on n‑3 fatty acids. Forty‑five White short‑haired goats were randomly allocated to three groups; the control group (C) with no supplementation microalgae to the diet. The first experimental group (Ch) was supplemented with Chlorella vulgaris and second experimental group (J) has been supplemented with Japonochytrium sp. The Japonochytrium supplementation negatively affected milk yield, but the amount of milk fat (+0.1 %; +0.45 %) and solids‑not‑fat (+0.27 %; +0.86 %) were higher than in group C and Ch. The amount of polyunsaturated (5.527 % ± 0.378) and saturated (71.560 % ± 0.861) fatty acids was also highest in group J. An increase of C20:4, C20:5 was detected in J and Ch, and the concentration of C22:6 was highest in group J (+0.019 %; P < 0.001).

Whole Cottonseed

Eight multiparous Holstein cows in mid lactation (average days in milking of 160 ± 40) were used in a replicated 4 by 4 Latin square design, each experimental period lasting 3 weeks, to determine the effects of whole cottonseed (WCS) treatment and dietary crude protein (CP) concentration on the profile of milk fatty acids. Each 3-week experimental period consisted of 2 weeks for ration adaptation followed by 1 week for data collection. The experimental diets consisted of: (1) Control (without WCS), 16% CP; (2) 20% WCS, 16% CP; (3) 20% WCS, 13% CP; and (4) 20% crushed WCS, 13% CP. Minerals and vitamin supplements were the same in all experimental diets. The WCS treatment led to increased DM intake, fat-corrected milk yield, fat concentration, proportion of long-chain fatty acids, unsaturated fatty acids and ratio of unsaturated to saturated fatty acids (P < 0.05). Decreased concentration of dietary CP from 16 to 13% (diet 2 compared with diet 3) led to a decrease in both milk yield and milk composition (P < 0.05). WCS crushed in diets with 13% CP (diet 4 compared with diet 3) increased (P < 0.05) the concentration of conjugated linoleic acid in milk fat. The results demonstrated that adding WCS to the diet of lactating cows improves both milk yield and milk fatty acid profile, particularly the proportion of conjugated linoleic acid.

Abstract. The present study investigated the effects of supplementing soybean oil (SBO) and sunflower oil (SFO) on the performance of early lactating Awassi ewes, growth of their sucking lambs and on the concentration of total fatty acids in milk and blood of suckling lambs. One hundred and twenty five ewes were randomly assigned into five equal sized treatment groups involved; a control total mixed ration (TMR) without added oil and four diets supplemented with 3 % SBO, 5 % SBO, 3 % SFO or 5 % SFO.
