SUMMARY:

In a recent research, our study group found that forage cactus (Opuntia stricta Haw, Haw) has a unique characteristic of reducing the 18:0 levels of milk from cows fed cactus cactus associated with vegetable oil. The objective was to evaluate the effects of the interaction between forage cactus and extra-fatty whole corn germ (GIMEX) on the fatty acid profile of goat milk fat. Twelve multiparous Saanen goats with average body weight of 54 ± 5.0 kg, initial production of 2.1 kg of milk/day and average lactation period of 45 ± 7 days were used. The animals were distributed in three simultaneous 4 x 4 Latin squares according to milk production and assigned to four treatments in a 2 x 2 factorial arrangement, corresponding to two energy sources (corn or GIMEX, representing 9.5% of the DM of the diet) and the presence or absence of Mexican elephant ear cactus (POEM). Elephant grass (Pennisetum purpureum) was used as forage exclusively or partially replacing forage cactus in the experimental diets. The diet containing forage cactus and GIMEX provided the highest CMS and PL (P = 0.03). There was an increase (P = 0.03) in milk fat contents with the use of GIMEX as an energy source. There was an increase in milk CP with the use of cactus associated with GIMEX. The diet containing cactus and GIMEX provided a significant increase (P< 0.001) in the concentration of CLA cis-9, trans-11 and 18:1 trans-11 in goat milk fat. At the same time, the use of GIMEX and forage cactus reduced the levels by 18:0. The use of diets containing forage cactus and GIMEX enhances the nutraceutical properties of goat's milk, which can add more value to the product and meet a growing market niche that increasingly aims to meet a healthy diet.
