4. Aspects of the reproductive biology of Zingiber spectabile (Zingiberaceae)
ABSTRACT Ginger (Zingiber spectabile) is cultivated worldwide as a floriculture and landscaping species. Studies on the biology and floral morphology of this species are important for its improvement; however, they are scarce. We investigated the reproductive biology and floral morphology of gingers grown in a germplasm bank. Floral development was monitored

5. EFFECTS OF VITAMIN E SUPPLEMENTATION ON SERUM HORMONES AND GENE EXPRESSION OF ANTI-SEASON BREEDING XINGGUO GREY GEESE (ANSER CYGNOIDES)
ABSTRACT The objective of this study was to analyse the impact of dietary vitamin E supplementation on laying performance, serum reproductive hormones concentration and gene expression in ovary and follicles of anti-season breeding goose. A total of 210 anti-season breeding geese were divided into seven treatments with six replications. Each group was suppli

6. ASPECTOS REPRODUTIVOS E DESEMPENHO DE DIFERENTES LINHAGENS DE MATRIZES DE CODORNAS JAPONESAS
Resumo Objetivou-se avaliar parâmetros reprodutivos e o desempenho de diferentes grupos genéticos de codornas japonesas com diferentes pesos iniciais de produção. O delineamento experimental utilizado para os dados de desempenho zootécnico das aves foi inteiramente casualizado, com esquema fatorial 3 x 2 (três linhagens: UEM1, UEM2 e Comercial (COM), e

7. Effects of long-term controlled internal drug release reuse on reproductive performance, hormone profiles, and economic profit of sheep
ABSTRACT Fifty-seven multiparous Awassi ewes in the breeding season were used to compare the effects of controlled internal drug release (CIDR) reuse on hormone profiles, reproductive performance, and economic production. Ewes were randomly allotted to one of three CIDR treatments: new (control), once-used, and twice-used; treatment lasted 12 days. Blood sam

8. Effect of live body weight and method of synchronization on ovulation, pregnancy rate and embryo and fetal loss in buffalo heifers
Abstract This study aimed to assess the influence of live body weight (LBW) and age on reproductive performance in buffalo heifers synchronized by different treatments. The study was carried out on 146 Mediterranean buffalo heifers (mean age 25.3±13.4 months, LBW 424±47 kg), divided into 2 homogeneous groups and synchronized by Ovsynch-TAI Program (OVS; n

10. Effects of Dietary Energy Concentration on Reproductive Hormone Secretion and Gene Expression in the Hypothalamus-Pituitary-Gonad Axis in Laying Geese
ABSTRACT The objective of the study was to investigate the mechanism by which dietary energy concentration regulates laying performance in geese. Eighty 558-day-old female Sichuan White geese were randomly allotted to two dietary treatments, each treatment was fed 1 of 2 experimental diets containing 10.00 (deficient) or 11.80MJ/kg metabolizable energy (suff

11. Desempenho e termorregulação de porcas lactantes alojadas em diferentes localizações no interior de um galpão com sistema de resfriamento evaporativo em ambiente tropical
ABSTRACT The effects of housing lactating sows at different locations in a shed with evaporative cooling system (ECS) on their thermoregulation and reproductive and productive performance of the sow and the litter in summer were determined. 34 females were used in the three lines of cages at these locations: near the pad cooling; in the middle of the shed an

12. Additional feeding during late gestation improves initial litter weight of lactating sows exposed to high ambient temperature
ABSTRACT The present study investigated the impacts of additional feeding (AF; containing 16% excess feed than control diet in the last two weeks of gestation) during late gestation period and different backfat thickness (BFT) including low (<20 mm) and high (≥20 mm) backfat on reproductive performance, litter size, blood metabolites, hormonal profiles, co
