Efecto de la restricción del amamantamiento y el aceite de soya en el desarrollo folicular y retorno a actividad reproductiva postparto de ovejas de pelo
Provedor de dados: 32
Autores: Herrera Corredor, Camelia Alejandra.
Se realizaron tres experimentos para determinar el efecto de un suplemento con aceite de soya (AS) antes de la inseminación y en periodo postparto (PP), así como el amamantamiento, en el desarrollo folicular, tasa ovulatoria (TO) y eficiencia productiva de ovejas de pelo. En el experimento 1 se proporcionó un suplemento con AS o concentrado comercial (CC) a ovejas en condición corporal alta (CA) y baja (CB): CBAS, CBCC, CAAS y CACC por 14 días antes y 7 días después del empadre, en 2 épocas. En el experimento 2, el suplemento con AS ó CC se proporcionó a ovejas en amamantamiento restringído (AR) y continuo (AC), del día 0 al 32 PP: ACCC, ACAS, ARCC y ARAS. DEl día 8 al 32 PP, las ovejas se examinaron diariamentepor ultrasonografía resgistrando el número,...

Se realizaron tres experimentos para determinar el efecto del amamantamiento y su interacción con el efecto macho, el  efecto del destete y el efecto del suplemento de aceite de soya durante el periodo postparto (PP) en la eficiencia reproductiva de ovejas Pelibuey. En el experimento 1, a los 7 d postparto, cuatro tratamientos se asignaron al azar a las ovejas con sus crías: amamantamiento continuo (AC), amamantamiento controlado (Ac), amamantamiento continuo con macho (ACCM) y amamantamiento controlado con macho (AcCM). A partir del día 7 al día 60 postparto, se tomaron muestras de progesterona dos veces por semana y por medio del ultrasonido se realizó el registró del día a que emergen  los folículos  4-5mm y folículos preovulatorio (FP; &gt;6mm).

Metabolic Profiles in Ovulatory and Anovulatory Primiparous Dairy Cows During the First Follicular Wave Postpartum
Provedor de dados: 19

Metabolic hormones affect ovarian function in the cow. However, the relationship between metabolic factors and ovarian function is not clear in the postpartum primiparous cow because they are still growing. The aim of the present study was to investigate in detail the time-dependent profile of the metabolic hormones, metabolites, and milk yields of ovulatory and anovulatory primiparous cows during the first follicular wave postpartum. We used 16 primiparous Holstein cows and obtained blood samples for the profiles of metabolites (glucose; non-esterified fatty acid, NEFA; ketone body; total cholesterol; and aspartate aminotransferase), metabolic hormones (growth hormone, GH; insulin-like growth factor-I, IGF-1; and insulin), and progesterone every other day...

The aim of this study was to investigate the relationship between the first ovulation within 3 weeks postpartum and subsequent ovarian cycles and fertility in high producing dairy cattle in Hokkaido, Japan. In Experiment 1, 110 cows (44 primiparous and 66 multiparous) were used to determine the effects of the first ovulation within 3 weeks postpartum on subsequent ovarian cycles. Milk samples were collected twice weekly from 7 to 100 days postpartum. The first ovulation was identified by an increase in milk progesterone (P4) to more than 1 ng/ml within 3 weeks postpartum. The numbers of cows showing ovulation and anovulation within 3 weeks postpartum were 31 (70.5%) and 13 (29.5%) in the primiparous cows and 35 (53.0%) and 31 (47.0%) in the multiparous...

This study was conducted to evaluate changes in hematological biomarkers of Nellore cows at different reproductive stages. Fifteen multiparous cows with 4 ± 1 years of age and live weight of 400 ± 50 kg were used at different stages (non-pregnant, in the initial, middle and late pregnancy, at birth, one day postpartum, 30 and 60 days postpartum). Blood collections were performed every 30 days and assayed for the following hematological biomarkers: hemogram (red blood cells, globular volume, hemoglobin, mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC)) and leukogram (total and differential counts). The erythrogram was influenced (p &lt; 0.001) by the reproductive stages, with variation in the results obtained for the total...

Provedor de dados: 42
Autores: RESENDE,FERNANDA B.S.; LIRA,LARISSA Q. DE; GRILO,EVELLYN C.; LIMA,MAYARA S.R.; DIMENSTEIN,ROBERTO.
The influence of gestational diabetes on vitamin A deficiency in lactating women and, consequently, in their newborn has been verified through a cross-sectional case-control study conducted with volunteer puerperal women. The control group consisted of healthy women and the test group was composed of women with gestational diabetes. One hundred and seven women were recruited, corresponding to 71 controls and 36 cases. Personal, gestational and newborn data were collected directly from medical records during hospitalization. The retinol was determined in maternal colostrum and serum by High Performance Liquid Chromatography. Postpartum women with gestational diabetes were older, had more children and a higher prevalence of cesarean delivery. No difference...

Metabolic stress and reproductive features in post-partum goats supplemented for a long period with detoxified castor meal as the source of dietary nitrogen
Provedor de dados: 45
Autores: Silva,L.M.; Oliveira,C.H.A.; Silva,A.M.; Montenegro,A.R.; Fernandes,C.C.L.; Silva,C.M.G.; Rossetto,R.; Rondina,D.
ABSTRACT This study evaluated the effect of detoxified castor meal on the reproductive performance, metabolic stress, milk production, and kid development in peripartum goats. The diet of the animals were with (DCM, n= 20) or without (WDCM, n= 21) detoxified castor meal during the entire gestation and until weaning, 60 days post-birth. No differences were observed in the gestation period, litter size, rate of multiple births, and mortality between the two groups. The postpartum plasma concentrations of progesterone remained below 1ng/mL in all animals, thus, confirming the absence of active corpora lutea. The thickness of sternum adipose tissue and loin area, levels of urea and cholesterol, milk production, and daily weight gain in the kids were low in the...

ABSTRACT:  The effect of insulin administration on the productive responses of Saanen goats during early lactation was investigated. Ten of 20 adult females were subjected to subcutaneous administration of intermediate-acting insulin (0.14UI/kg body weight) at 2, 9, and 14 days postpartum. Milk yield was measured twice daily for 13 weeks and milk samples were collected to measure protein and fat contents. Plasma levels of progesterone, insulin, non-esterifies fatty acids, glucose and other metabolites were measured. Results showed a significantly increased effect of insulin treatment on the content of milk fat and protein; moreover, milk production in the first and second postpartum weeks were higher than control group. The peak of lactation in the insulin...

Provedor de dados: 65
Autores: Borges,Luiz Felipe Kruel; Ferreira,Rogério; Siqueira,Lucas Carvalho; Bohrer,Rodrigo Camponogara; Borstmann,Jacson William; Oliveira,João Francisco Coelho de; Gonçalves,Paulo Bayard Dias.
The aim was to develop a timed artificial insemination (TAI) system in suckled beef cows. Cows (n=227), 60-80 days postpartum, received estradiol benzoate (5mg) and a vaginal device containing 250µg of medroxyprogesterone acetate (MPA; day 0). On day six, cloprostenol (125µg) and eCG (400IU) were administrated and calves were weaned for 88h. The devices were removed on day seven (BioRep group) or on day eight (TAI group). All cows of TAI group and cows of BioRep group that did not exhibit standing estrus received GnRH (100µg) on day 9. In experiment I, the follicular growth was monitored daily by transrectal ultrasound exams, from day 6 to day 9. The average size of the dominant follicle on day nine was 11.1±0.99mm (BioRep, n=7) and 11.5±0.65mm (TAI, n=7)...
