This study aimed to describe ovarian follicular dynamics in Boer goats (n = 14) during thebreeding and non-breeding seasons in the tropics of Queensland. Progesterone profiles andfollicular dynamics were compared over a 21-day period in the non-breeding season andone oestrous cycle in the breeding season. Between September and October, 100% of goatswere in anoestrus while between April and May they were all undergoing ovulatory cycles.The number of follicular waves during a 3-week period of monitoring was greater duringthe non-breeding compared to the breeding season (4.8 ± 0.1 vs 4.1 ± 0.1, respectively;P < 0.05), while the number of codominant follicles (5.6 ± 0.3 vs 6.8 ± 0.3, respectively;P < 0.05), growth rate (0.61 ± 0.05 mm/day vs 0.81 ± 0.05 mm/day, respectively; P < 0.05)and the diameter of the largest follicle measured within follicular waves (6.7 ± 0.1 mm vs7.8 ± 01 mm, respectively; P < 0.05) were less in the non-breeding compared to the breedingseason. During the breeding season the interovulatory interval was 19.7 ± 0.2 days. Totalnumber of small follicles (2?3 mm) and the total number of follicles ≥3 mm from Days 2 to14 of the period of examination were greater (P < 0.05) during the non-breeding comparedto the breeding season. In the breeding season, 35.7% of cycling goats showed large anovula-tory follicles, which persisted and became luteinized. Ovulatory follicles were derived fromthe fourth follicular wave in 71% of goats. These results have described differences in char-acteristics of follicular development in the same Boer goats examined during the breedingand non-breeding seasons. In the non-breeding season, the ovaries remained active andfollicles continued to grow to reach the equivalent size of preovulatory follicles. Folliculardynamics in the breeding season was characterized by the development of larger folliclesand greater follicular growth rates. Short oestrous cycles and follicular cysts may reduceovulation rate in Boer goats in the breeding season.

Embrapa Agroenergia has been conducting genetic improvement of filamentous fungi to increase the production of cellulases and hemicellulases to deconstruct lignocellulosic biomass. In a conventional breeding program for Aspergillus niger 3T5B8 performed in 2015, after two rounds of mutagenesis (ultraviolet followed by ethyl methanesulfonate), the pectinolytic mutant strain 3T5B8-C88-P83 was selected, which presents genetic changes in the catabolite repression by glucose pathway and a significant increase in polygalacturonase production compared to the original 3T5B8 strain. This work aimed to evaluate the production of cellulolytic and hemicellulolytic enzymes of the 3T5B8-C88-83 mutant under different cultivation conditions, seeking its future application in the enzymatic processing of cotton fabrics. Endoglucanase production by the 3T5B8-C88-P83 mutant strain was evaluated in 250 mL Erlenmeyer flasks containing different liquid and solid culture media (four repetitions). |
