Embryo quality is influenced by the culture conditions that affect in vitro maturation (IVM), fertilization (IVF) and culture (IVC) rates. The present study investigated the feasibility of producing bovine embryos after the replacement of fetal calf serum (FCS) and bovine serum albumin (BSA) by ovalbumin (OVA). The IVM and IVC medium were supplemented with 10% FCS, 4 mg/mL BSA, or 4 mg/mL OVA. The IVF medium was supplemented with 6 mg/mL BSA or OVA. For IVM, supplementation with FCS, BSA, and OVA did not affect nuclear maturation or cortical granule migration. Higher rates of formation of two pronuclei were obtained when FCS was employed for IVM (79.97%), regardless of the supplement used for IVF, and when BSA was used for IVF (59.4%), regardless of the supplement used for IVM. Supplementation with OVA for IVM+IVC (20.40%) and for IVF (22.15%) was inferior to supplementation with FCS for IVM+IVC (30.47%) and with BSA for IVF (28.91%) for blastocyst development. Hatching rates were lower using OVA for IVM+IVC (23.02%) and for IVF (28.93%) compared with FCS and BSA under the same conditions (40.78 and 34.82%, respectively) and BSA for IVF (36.82%). Supplementation with OVA for IVM+IVC and IVF resulted in reduced inner cell mass, trophectoderm cells and total blastocyst cell numbers (17.29, 37.88, and 55.17, respectively). In conclusion, OVA is a protein source for bovine in vitro embryo production, although the quantity and quality of bovine blastocysts using only ovalbumin in the entire in vitro production process are lower than those obtained in the presence of FCS and BSA, when used as supplements in any step of bovine in vitro embryo production.

Peanut (Arachis hypogaea L.) is an important crop for the family-based systems in the tropics, mainly in Brazil. In the Brazilian drylands, peanuts are cropped in low technological systems, and cheap and efcient technologies are needed to improve crop yield and sustainability. Despite this importance, few data are available on selecting efcient peanut rhizobia in experiments under diferent edaphoclimatic conditions. This work evaluated the agronomic efciency and the biological nitrogen fxation (BNF) by two elite Bradyrhizobium strains under four diferent felds in the Brazilian semiarid region. We compared a new efcient strain Bradyrhizobium sp. ESA 123 with the reference strain B. elkanii SEMIA 6144, currently used in peanut rhizobial inoculants in Brazil. Besides the inoculated treatments, two uninoculated controls were assessed (with and without 80 kg ha−1 of N-urea). The BNF was estimated by the δ15N approach in three out of four feld assays. BNF contribution was improved by inoculation of both Bradyrhizobium strains, ranging from 42 to 51% in Petrolina and 43 to 60% in Nossa Senhora da Glória. Peanuts? yields benefted from the inoculation of both strains and N fertilization in all four assays. Nevertheless, the results showed the efciency of both strains under diferent edaphoclimatic conditions, indicating the native strain ESA 123 as a potential bacterium for recommendation as inoculants for peanuts in Brazil, mainly in drylands. |
