The study aimed to characterize morpho-functional changes in corpus luteum (CL) in pregnant and non-pregnant sheep, propose diagnostic criteria for non-pregnancy, and assess diagnostic accuracy around the expected luteolysis period. Crossbred ewes (n = 34) underwent estrous synchronization, divided into G1 (unmated, n = 20) and G2 (mated, n = 14). The day of ovulation was considered as day 0 (D0). Luteal dynamic was monitored from D0 to D17, with blood samples collected every 72 h for progesterone (P4). Pregnancy was definitively diagnosed at day 30. Analyses included CL area (CLA), CL blood flow (CLBF), CLBF:CLA ratio, and serum P4. Statistical models considered group, day, and interactions. Accuracy for early pregnancy diagnosis (days 12–17) was assessed. CLBF:CLA ratio (14.3 ± 8.1 vs. 20.3 ± 10.7; 10.2 ± 10.4 vs. 17.8 ± 9.4; 1.3 ± 4.1 vs. 16.0 ± 8.2%), CLBF (0.41 ± 0.3 vs. 0.49 ± 0.3; 0.26 ± 0.3 vs. 0.45 ± 0.3; 0.06 ± 0.2 vs. 0.34 ± 0.2 cm2), and CLA (2.5 ± 1.1 vs. 2.3 ± 0.9; 1.9 ± 1.1 vs. 2.3 ± 1.1; 0.9 ± 1.2 vs. 2.0 ± 1.2 cm2) differed (P < 0.05) between pregnant and nonpregnant ewes at days 13, 14, and 16 after ovulation, respectively. The early diagnosis of nonpregnancy achieved accuracy values > 90% from day 15 on for CLBF and CLBF:CLA ratio, but not for CLA. At this day, CLBF and CLBF:CLA ratio were circa 50-fold greater in pregnant than in nonpregnant ewes (p < 0.0001). No ewe classified as in the 1st or 2nd quartiles for CL endpoints or P4 concentration was confirmed as pregnant at day 30. In summary, the diagnosis of nonpregnancy based on the objective evaluation of CLBF could be performed in sheep as early as at day 15 after ovulation.

Yam, cassava, jackfruit seed and mango seed kernel have potential for the extraction and use as starch in the food industry of starch or for the formulation of biodegradable coatings. As a biodegradable coating, starch can be applied in fruits characterized by a fast maturation, such as mango, which requires technologies to increase its shelf life. The aim of this study was to characterize starch from four non-traditional sources and to evaluate their potential as coating for ?Palmer? mango fruit. Starches used were extracted from cassava, mango seed kernel, jackfruit seed, and yam, and had their physical, optical, and chemical properties characterized for later use as coatings of ?Palmer? mango fruit. Fruits were coated with 3% cassava starch, 3.5% jackfruit seed starch, 3.5% mango seed kernel starch and 3.5% yam starch, and were compared to the control (uncoated). They were then stored at 24.4 ± 0.3 °C and 87 ±
2% RH and evaluated for 12 days. A 5x7 factorial arrangement in a completely randomized experimental design was adopted. Total starch content was higher than 70% in the four sources of starch. Starches from jackfruit and yam had higher amylose content. The four sources of starch had low water solubility and swelling power, with jackfruit seed starch having the highest values. The coating sources were effective in maintaining quality, particularly mango seed kernel starch because it reduced respiratory rate and weight loss in 27.7% and 33.8%, respectively, as well as jackfruit seed starch as it delayed fruit skin yellowing.
