Fatty Acid Profile of Milk and Cheese from Dairy Cows Supplemented a Diet with Palm Kernel Cake

To evaluate the fatty acid profile of milk from cows fed palm kernel cake (PKC), 12 Holstein × Zebu crossbred cows were kept in the feedlot, distributed into a triple 4 × 4 Latin square, and fed the following treatments: 1) control; 2) inclusion of 50 g PKC/kg in the total dry matter (TDM); 3) inclusion of 100 g PKC/kg in the TDM; and 4) inclusion of 150 g PKC/kg in the TDM. Milk samples from the morning and afternoon milkings were collected in the amount of 1% of the daily production of each animal; subsequently, 100-mL subsamples were frozen for analysis of the fatty acid profile. Inclusion of PKC did not change the concentration of short-chain fatty acids or myristoleic (C14:1), pentadecenoic (C15:1), palmitic (C16:0), and palmitoleic (C16:1) fatty acids. Concentrations of medium-chain and lauric (C12:0) and myristic (C14:0) fatty acids increased linearly (P < 0.05). A decreasing linear effect was observed (P < 0.05) on the concentration of the C15:0 fatty acid. No effects were observed (P > 0.05) on the long-chain fatty acids and those of the omega 6 and 3 series; on the ratio between poly-unsaturated and saturated fatty acids; or on the ratio between the fatty acids of the omega 6/omega 3 series. The concentration of conjugated linoleic acid was not influenced (P > 0.05) by inclusion of PKC in the diet. Addition of palm kernel cake to the diet of lactating cows influences the concentration of medium-chain fatty acids, and of lauric (C12:0), myristic (C14:0), and pentadecanoic (C15:0) fatty acids in their milk.

Plasma Fatty Acid Profile

The objective of this study was to evaluate the plasma lipid profile and plasma fatty acids of dairy cows receiving diets supplemented with annatto. A total of 32 Holstein cows (550 kg), distributed in a completely randomized design, were allocated to individual stalls and submitted to following treatments: C0 = no annatto; C4 = inclusion of annatto at 4 g kg-1 dry matter (DM) of diet (0.07 g bixin kg-1 diet); C5 = inclusion of annatto at 5 g kg-1 DM of diet (0.09 g bixin kg-1 diet); and C7 = inclusion of annatto at 7 g kg-1 DM of diet (0.12 g bixin kg-1 diet). Blood samples were collected via epigastric vein puncture, centrifuged, and frozen for subsequent analysis. The results indicate that the inclusion (p > 0.05) of annatto does not decrease the total cholesterol or low and high density lipoproteins. However, it impacts the profile of fatty acids, evidenced by the reduction (p < 0.05) in levels of hypercholesterolemic fatty acids viz, myristic acid and palmitic acid. It also causes an increase in the levels of arachidonic acid, rumenic acid, linoleic acid, and total polyunsaturated fatty acids. Therefore, bixin included in the diets of dairy cows induces changes in the plasma fatty acid profile.
