“…The highest average value of CLA obtained in this experiment, was higher than those recorded in Brazil by Oliveira et al (2009) with diets based on corn and soybean (5.08 to 6.91mg/g fat). However, this value was lower in diets with soybean oil, (10.80mg/g fat) and in buffaloes fed only with Brachiaria grass (Brachiaria decumbens) the value was 11.0mg/g fat (Caldeira et al, 2010).…”

The aim of this research work was to investigate the influence of fish oil supplementation on the concentration of conjugated linoleic acid (CLA) and omega 6 and 3 in samples of buffalo milk. A total of 24 female buffaloes separated at random into three groups were fed for 49 days with: natural pasture (group I), supplemented with 70mL of fish oil (group II) and 140mL of fish oil (group III). In the experiment the concentration of CLA showed differences (P<0.05) among the three groups, with a maximum of 7.14mg/g fat in group II. No significant differences were found in omega-6 among the three groups. The highest value of 3.82mg/g fat corresponded to group I, whicht had not been supplemented with fish oil. Significant differences were observed in omega 3 (P<0.05) in groups II and III with respect to group I. The highest average value of 2.42mg/g fat was obtained in group III. The closest relationship omega 6/3 (1.37:1) was observed in group III. As a result, the diets of groups II and III, which included fish oil, increased significantly the content of CLA and omega 3 with reductions in levels of omega 6.Keywords: Bubalus bubalis, milk, CLA, Omega 6 and 3, fish oil RESUMO Estudou-se a influência da suplementação com óleo de peixe sobre a concentração dos ácidos graxos ômega 6 e 3, mostrado no leite de búfala.

“…Supplementation with PUFA-rich oils did not affect milk yield in non-grazing (Gagliostro and Chilliard, 1992) or in grazing experiments (Schroeder et al, 2004) with dairy cows. Basal content of total solids in milk (17.6%) was in the normal range (17% to 18.1%) reported by Oliveira et al (2009) using confined buffaloes and Ahmad et al (2013) for their review on general composition of buffalo milk. After oil feeding this parameter increased up to 21.89g/100g probably as the consequence of the higher milk protein content after the intake of oil.…”

“…These FA (14:0 and 16:0) are classed as atherogenic (Ulbritch and Southgate, 1991) if consumed in excess and associated to increased risk of heart disease (Stanton el al., 2003;Chilliard and Ferlay, 2004). The supplementation with polyunsaturated rich oils may decrease the concentration of the potentially atherogenic FA in cows (Rego et al, 2005) and in lactating buffaloes (Oliveira et al, 2009). Concerning the potential functional benefits of milk, a current special interest exists on conjugated linoleic acid (CLA) concentration, because it plays an important role in regulating plasma lipid concentrations and cardiovascular functions, reducing cancer incidence, as well as blocking tumor growth and metastasis from cancer breasts (Parodi, 1999).…”

“…Buffalo milk contains higher amounts of RA and VA than cow milk (Ahmad et al, 2013;Ménard et al, 2010).). Milk fat is considered the main natural source of RA and its concentration in milk is highly dependent on the type of diet and lipid supplementation in dairy cows (Chilliard et al, 2007) and buffaloes (Fernandes et al, 2007;Patiño et al, 2010, Oliveira et al 2009). To our knowledge the information about the effect of providing a combination of soy and linseed oils on the full milk FA profile of grazing buffaloes is non-existent.…”

The aim of the study was to examine the changes in milk fatty acid (FA) profile of grazing buffaloes fed either low (L, 276g/d) or high (H, 572g/d) doses of a blend (70:30, wt/wt) of soybean and linseed oils. Fourteen multiparous Mediterranean buffaloes grazing on a native pasture were fed 4 kg/day of a commercial concentrate containing no supplemental oil over a pre-experimental period of ten days. The baseline milk production and composition and milk FA profile were measured over the last three days. After this pre-experimental period the animals received the same concentrate added with either the L or H oil doses for 26 additional days. Milk yield (g/animal/day) did not differ at the start (1776 ± 522 and 1662 ± 291 for L and H, respectively, P<0.622) or at the end of the trial (4590 ± 991 and 4847 ± 447 in L and H, respectively, P<0.543). Baseline milk fat content (g/kg) averaged 77.1 (±20.5) in L and 74.3 (±9.9) in H (P<0.10) and was reduced (P<0.031) to 60.7 (±23.6) and 49.4 (±11.2) (P<0.0031) respectively after L and H with no differences between treatments (P<0.277). Baseline milk protein content (L=43.2 ± 3.4 and H= 44.3 ± 6.9g/kg) increased after oil supplementation (P<0.0001) in both L (73.2 ± 6.0g/kg) and H (68.4 ± 4.9g/kg) without differences between oil doses (P<0.123). Milk fat content of 14:0 decreased after oil supplementation only in the H treatment (5.29 to 4.03, P<0.007) whereas that of 16:0 was reduced (P<0.001) at both L (24.49 to 19.75g/100g FA) and H (25.92 to 19.17g/100g FA) doses. The reduction of total content of 12:0 to 16:0 was higher (P<0.052) in H (32.02 to 23.93g/100g FA) than L (30.17 to 25.45g/100g FA). Vaccenic acid content increased (P<0.001) from 5.70 to 13.24g/100g FA in L and from 5.25 to 16.77 in H, with higher results in the in H treatment (P<0.001). Baseline rumenic acid was sharply increased (P<0.001) in L (1.80 to 4.09g/100g FA, +127%) and H (1.60 to 4.61g/100g FA, +187%) with no differences between L and H (P<0.19). Overall, these results indicate a pronounced improvement in the nutritional value of milk fat from grazing buffaloes fed little amounts (0.276g/day) of a blend of soybean and linseed oils.

Milk and Minas frescal cheese were evaluated from crossbred Holstein × Gir cows that were fed diets enriched with 0, 33, 66 and 100% inclusion levels of palm kernel cake in a concentrated supplement in replace of soybean meal. Eight crossbred lactating cows were distributed (four animals × four treatments × four periods) in the experimental design of double 4 × 4 Latin squares. The capric (C : 10, P = 0.0270), undecylic (C : 11, P = 0.0134), and lauric (C : 12, P = 0.0342) saturated fatty acid concentrations and CLA (C18 : 2c9t11, P = 0.0164) of the milk fat decreased linearly with an increasing percentage of peanut cake in the diet. The increased peanut cake content (100%) in the diet was associated with a linear decrease in C : 10 (P = 0.0447), C : 12 (P = 0.0002), mirystic (C : 14, P 0.05) ratios were not influenced by the different peanut cake levels. The inclusion of up to 100% peanut cake as a substitution for soybean meal in the concentrate of grazing lactating cows resulted in changes in the nutritional quality of their milk products, as indicated by the increase in polyunsaturated fatty acids and the decrease of saturated fatty acids (lauric, myristic, and palmitic).
