Abstract:
The incidence of physiological disorders originating during postharvest handling and storage in citrus fruits have been for many years, and will continue to be, one of the main factors that negatively impacts fruit quality, accounting for significant financial losses. Postharvest physiological disorders of citrus fruit, in most cases, affect mainly the peel and manifest as injuries, pitting, darkening of the tissue, and browning, whereas the pulp, which is a physiologically separate unit of the fruit, remains unaffected. Low temperature storage is the most widely applied technology to extend the postharvest life of citrus fruit. The characteristic darkening of most chilling-injured fruit is most likely due to the internal release and oxidation of the contents of oil glands. Cold also provokes important modifications in the cell wall structure. CI development in citrus fruit has been associated with the production of reactive oxygen species (ROS), which are directly involved in the oxidative stress damage of different molecules. |

This study evaluated the relationship between proestrus length and follicular size, estrous behavior, and pregnancy rate in Bos taurus beef heifers subjected to ixedetime artificial insemination (FTAI). A total of 911 heifers received a synchronization treatment protocol for FTAI (JeSynch) consisting of an intravaginal
progesterone device for 6 d, estradiol benzoate at the time of device insertion cloprostenol sodium and eCG at device removal and GnRH at the time of FTAI. The presence or absence of a corpus luteum (CL) was determined by ultrasonography at device insertion and all heifers were tail painted at device removal for estrus detection at the time of FTAI. For the establishment of different periods of proestrus length (i.e., interval from device removal to FTAI), GnRH was administered i.m. at 48 h (n ¼ 308), 60 h (n ¼ 290) or 72 h (n ¼ 313) after device removal. The diameter of the largest follicle at the time of GnRH administrationwas determined by ultrasonography, expression of estrous was determined by percentage of tail paint removal, and FTAI was performed at the time of GnRH administration in all heifers. The diameter of the largest follicle was greater when GnRH/FTAI was performed at 72 or 60 h (12.9 ± 0.2 mm and 12.8 ± 0.1 mm, respectively) than at 48 h (12.2 ± 0.1 mm, P < 0.05). The proportion of heifers in estrus tended to be greater when GnRH/FTAI was performed at 72 h (77.0%, 137/178) than at 48 h (68.2%,
122/179; P ¼ 0.06), and intermediate at 60 h (71.4%, 120/168). Pregnancy rate tended to be greater in heifers with the longest (72 h: 70.0%, 219/313) than the shortest (48 h: 63.6%, 196/308; P < 0.1) proestrus length, while 60 h proestrus length was intermediate (63.1%, 183/290; P¼ NS). Pregnancy rate was
affected by the presence of a CL at device insertion (71.3%, 352/494 in heifers with a CL, vs. 59.0%, 246/417 for those without a CL; P < 0.01). For those heifers bearing a CL, pregnancy rate was greater in heifers with a 72 h proestrus length (77.0%, 134/174) than with 48 or 60 h proestrus length (67.7%, 107/158 and
68.5%, 111/162; respectively; P < 0.05). In heifers without a CL, proestrus length did not affect pregnancy rate. In summary, extending proestrus length by delaying the interval from device removal to GnRH/FTAI from 48 to 72 h, was associated with a greater diameter of the preovulatory follicle, greater proportion of heifers expressing estrus at the time of FTAI, and greater pregnancy rate in cycling beef heifers.
