Abstract: This study was conducted to evaluate effects of two administrations of d-cloprostenol at different intervals to synchronize the time of estrus and ovulation among estrous cyclic goats. In Experiment 1, 32 does were treated with 30??g?d-cloprostenol at 7.5 (T7.5, n = 16) or 11.5-day (T11.5, n = 16) intervals. In Experiment 2, the same treatments were administered and there was AI of the does (T7.5, n = 40 and T11.5, n = 38). In Experiment 1, ultrasonic assessments of ovaries were conducted at the time of the second administration of d-cloprostenol, every 12?h until detection of ovulation, and 7 days after estrous onset to detect the corpora lutea, as well as for pregnancy diagnosis 40 days after AI. In Experiment 1, the estrous response (90.6%, 29/32) was similar (P?>?0.05) in both groups. Diameter of the largest follicle at the time of administration of the second dose was larger (P = 0.01) in the T7.5 than T11.5 group (7.0 compared with 5.7?mm), while the values for ovarian variables were similar (P?>?0.05). In Experiment 2, the greatest (P?

In Experiment 2, the greatest (P?<?0.001) synchrony in timing of initiation of estrus in does (T7.5 = 83.3% and T11.5 = 50.0%) occurred after the second day (36-48?h). The pregnancy rate tended (P = 0.0836) to be greater for does in the T7.5 (71.4%, 40/56) than T11.5 (55.6%, 30/54) group. With use of both protocols, there were acceptable estrous synchronization and pregnancy rates in estrous cyclic dairy goats.

ABSTRACT: Two multivariate methods were adopted to classify salt-tolerant cotton genotypes based on their growth and physiological traits. The genotypes were cultivated in a greenhouse and subjected to 45 days of irrigation with saline water from the V4 phase onwards. Irrigation was performed with saline water with electrical conductivity (ECw) of 6.0 dS m-1. A factorial-randomized block design was adopted with nine cultivars, two treatments of ECw (0.6 as the control, and 6.0 dS m-1), and four replicates. Plants were evaluated for growth, gas exchange, and photosynthesis. The data were statistically analyzed using univariate and multivariate methods. For the latter, non-hierarchical (principal component, PC) and hierarchical (UPGMA) models were used for the classification of cultivars. Significant differences were found between cultivars based on univariate analyses, and the traits that differed statistically were used for multivariate analyses. Four groups were identified with the same composition in both the PC and UPGMA methods. Among them, one contained the cultivars BRS Seridó, BRS 286, FMT 705, and BRS Rubi, which were tolerant to salt stress imposed on the plants. Photosynthesis, transpiration, and stomatal conductance data were the main contributors to the classification of cultivars using the principal component method. Dois métodos multivariados foram adotados para classificar genótipos de algodoeiro tolerantes ao sal com base no crescimento e nas características fisiológicas. Os genótipos foram cultivados em casa de vegetação e submetidos a 45 dias de irrigação com água salina, a partir da fase V4. A irrigação foi feita com água salina com CEa de 6,0 dS m-1. O delineamento experimental foi em blocos casualizados com fatorial, sendo nove cultivares, dois tratamentos (controle: 0,6 e 6,0 dS m-1) e quatro repetições. As plantas foram avaliadas quanto a variáveis de crescimento e fisiológicas. Os dados foram analisados estatisticamente por meio de analises univariada e multivariada. Nesse último, os modelos não hierárquicos (componentes principais, CP) e hierárquico (UPGMA) foram usados para classificação das cultivares. Diferenças significativas foram encontradas entre as cultivares com base nas análises univariadas. As variáveis que diferiram estatisticamente foram usadas para as análises multivariadas. Quatro grupos foram identificados com a mesma composição nos métodos PC e UPGMA. Entre eles, um conteve as cultivares BRS Seridó, BRS 286, FMT 705 e BRS Rubi, que se mostraram tolerantes ao estresse salino imposto as plantas. Os dados de fotossíntese, transpiração e condutância estomática foram os mais contributivos para classificação das cultivares, pelo método das componentes principais.
