Produção de queijo artesanal “tipo minas frescal”: efeito da suplementação lipídica na alimentação de ovelhas pantaneiras

Abstract

The objective of this work was to evaluate the effect of the inclusion of protected fat of soybean and palm, and deactivated soybean grain on the quality of milk yield of Pantaneira sheep. Twenty-five sheep of the Pantaneira breed were used, with 65 days of lactation, age between 3 and 6 years and weight of 39.8 ± 3.51 kg. The animals were allocated in individual stalls to determine the consumption per animal. The treatments were: control (Con), protected soybean fat (GPS, 30 g / day), protected palm fat (GPP, 30 g / day), combination of the two protected fats (Blend, 30 g / day) and grain deactivated soybean (GSD, 124 g / day). The ewes were fed a commercial concentrate (CC) according to dairy production (1 kg of concentrate to 1 kg of milk). As a bulky source, hay was supplied from Oat and Typhton ad libitum. Cheeses were produced according to the treatments and instrumental, chemical and sensorial applied analyzes were evaluated to determine the acceptance. Control treatments, protected soybean fat, protected palm fat, the combinations of the two protected fats and the deactivated soybean grain showed no difference (P> 0.05) in the color, pH, moisture, dry extract, protein, mineral matter and fat content. The results of the sensorial analysis presented a difference (P> 0.05) between treatments. The acceptability index of the combination of the two protected fats presented levels above 70% among the variables: taste, color, aroma, overall appreciation and overall appearance. The deactivated soybean grain had an acceptability of less than 70% in attributes of general appearance, color, aroma and consistency.
