Crushed flaxseed versus flaxseed oil in the diets of Nubian goats: Effect on feed intake, digestion, ruminal fermentation, blood chemistry, milk production, milk composition and milk fatty acid profile

The objective of this study was to evaluate the effects of supplementation of dairy cows with different fatty acid sources (soybean oil (SO) and fish oil (FO)) on milk production, milk composition, milk fatty acid profile, and physicochemical and sensory characteristics of ice cream. During 63 days, fifteen Holstein cows averaging 198 ± 35 days in milk were assigned to three groups: control diet with no added lipid (n = 5 cows); and supplemented diets with SO (n = 5 cows; unrefined SO; 30 g/kg DM) or FO (n = 5 cows; FO from unrefined salmon oil; 30 g/kg DM). Milk production, milk fat, and milk protein were not affected by treatments. Saturated fatty acids in milk fat were decreased with SO and FO compared with control. C18:2 cis-9, cis-12 was increased with SO whereas C18:2 cis-9, trans-11, C20:3n-3, C20:3n-6, C20:5n-3, and C22:6n-3 were the highest with FO. Draw temperature and firmness were higher in SO compared to control and FO ice creams. Melting resistance was higher in FO compared with control and SO ice creams. Supplementation of cow diets with SO and FO did not have detrimental effects on milk production, or ice cream physicochemical and sensory characteristics.

Abstract The aim was to assess if the replacement of fatty acid salts by oil seeds in diet of dairy cows and their effects about intake and digestibility, milk production and composition, feed efficiency, metabolic profile and milk fatty acid profile. Lipid sources evaluated were calcium salts of fatty acids (CS), linseed (LI), sunflower (SF) and soybean (SY). Diets were iso in protein, fiber and energy, with 58 g/kg (mean) of crude fat in dry matter. There were no differences (P > 0.05) in the intake of nutrient fractions. The protein digestibility was lower for SY (P < 0.001) due the fraction derived from the grain in that treatment. The ether extract digestibility was higher for CS treatment (P < 0.001), and no difference was found between the grains sources. Milk production was higher in CS, when milk production was corrected for energy, these differences disappeared. Little effect on milk composition (g/kg) was observed, only for lactose. The sources used do not affect feed efficiency, energy balance and blood metabolic profile. in CS. When observed milk fatty acid profile, there was an increase influence by CS There was no difference for saturated and polyunsaturated fatty acids (PUFA), however, monounsaturated fatty acids (MUFA) were higher for SF (P = 0.0172). The lipid sources evaluated can be used in early lactation without negative effects being able to replace calcium salts of fatty acids in diets.

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.
