There are many varieties of native potatoes grown in different regions of Peru, usually for farmers´ consumption. However, the possibility of a commercial use has led this work in order to give them added value. To evaluate the possibility of use of native starch from these potatoes, as an ingredient in the food industry, it was presented as objective to determine the physicochemical, functional and viscoelastic native potato starches obtained from Pampacorral properties (Cuzco, Peru): Puka Ambrosio (PA), Combe (CO), Perwanita (PER), Kalis qero (KQ), Qello virondos (QEV), Yana churos (YACH), Pitikiña (PI), Yana kusi (YAKU) y Solischa (SOL). For this purpose, slurries were prepared from native starch by heating until gelatinization. Moisture sorption, swelling and solubility showed were correlated with temperature increment. At 90 °C, PI starch showed greater values for swelling power ...

The ovarian follicular dynamics monitored by transrectal (TR) and transvaginal (TV) routes in successive waves was studied in 10 llamas older than 4 years, multiparous, without calves at foot, body condition of 3.0, during a period of 90 days in the reproductive season. The Sonostar SS8® ultrasound equipment was used with a linear transducer for transrectal examination and endocavitary microconvex transducer for transvaginal examination, both with a frequency of 6.5 MHz. The inter-wave interval was 20 ± 4.4 and 22.5 ± 5.3 via TR and VT, respectively; the number of follicles per cohort was 5.21 ± 0.92 and 6.38 ± 1.26 for TR and TV, respectively (p=0.0011); the maximum diameter of follicles was 12.49 ± 3.57 mm for TR and 13.56 ± 3.91 mm for TV; the growth rate was 0.70 ± 0.35 and 0.67 ± 0.32 mm/day for TR and TV, respectively. The regression equation for the ratio of the maximum f...
