1. Inseminação artificial em tempo fixo em primíparas nelore lactantes acíclicas / Fixed Time Artificial Insemination in Lactating Primiparous Acyclic Nelore Cows
The objective of this experiment was to evaluate the efficiency of a Fixed Time Artificial Insemination (TAI) protocol in an attempt to improve the reproductive performance of primiparous lactating acyclic Nelore cows. The experiment was conducted for a period of breeding season (BS) of 180 days. Were used 350 Nelore cows with body condition score (BCS) grea

2. Nova pipeta para inseminação intra-uterina em suínos / New pipette for intrauterine insemination in pigs
O objetivo deste trabalho foi avaliar o desempenho reprodutivo de 423 fêmeas suínas de ordem de parto 1 a 9 submetidas à inseminação intra-uterina (IAU), com um novo modelo de pipeta (T1) cuja extremidade não é fixada na cérvix ou uma pipeta de IAU modelo Verona® e que permite a fixação da sua extremidade em espiral na cérvix (T2).

3. Uso de cloprostenol e cipionato de estradiol, durante o puerpério, sobre a saúde uterina e a eficiência reprodutiva em fêmeas girolando / Use of cloprostenol and estradiol cypionate, during the postpartum on uterine health and reproductive efficiency in females girolando
The aim is to find ways of management to improve reproductive efficiency of dairy herds in recent post-partum through the use of analogues of PGF2(alfa) or cypionate of oestradiol, which may improve uterine health and reproductive efficiency. We used one hundred and fourteen cows girolandas randomly divided into three groups: CON - control; PGF2(alfa) - trea

4. EFEITOS DA INCLUSÃO DE ÁCIDOS GRAXOS INSATURADOS NO SUPLEMENTO DE VACAS PRIMÍPARAS ZEBUÍNAS SOBRE O DESEMPENHO PRODUTIVO E REPRODUTIVO / Effects of inclusion of unsatured fatty acids in the supplement of primiparous cows zebuine on productive and reproductive performance
Were used primiparous cows, zebuine, calved than received in the postpartum period, low intake isoenergetic supplements, in pasture of Brachiaria brizantha cv. Marandu, with twenty cows per treatment in a randomized design, where FA: the low intake supplement (LIS) with inclusion of protected fat, CO: LIS with the inclusion of meal corn and MS: only mineral

6. Suplementação mineral e desempenho reprodutivo no período pós-parto de vacas primíparas de corte / Mineral supplementation and reproductive performance in the postpartum of primiparous beef cows
The objective of this work was evaluate the reproductive performance of primiparous beef cows, in real system of production, in the postpartum period, supplemented in a group with common mineral supplement and in another one, specific mineral supplement for reproduction. Also was evaluated the response of these females submitted to the Ovsynch protocol of sy

7. Effect of equine chorionic gonadotropin (eCG) and human chorionic gonadotropin (hCG) in the post weaning fertility in primiparous and pluriparous sows / Efeito das Gonadotrofinas coriônicas equina (eCG) e humana (hCG) na fertilidade pós-desmame em femeas suínas primíparas e pluríparas
The objectives of this experiment were to compare the estrous rate, the concentration of the estrous period, the weaning-to-estrous interval (WEI), the gestation, farrowing and live piglets rates and the litter size in primiparous (P1) and pluriparous sows of second farrowing (P2), treated with 400 UI of eCG and 200 UI of hCG (PG 600, Intervet), on the same

8. Influence of the lactation period on the reproductive efficiency of females swine / Influência do período de lactação na eficiência reprodutiva de fêmeas suínas
This experiment was carried out to verify the influence of the lactation period (LP) in the subsequent weaning-conception interval (WCI) and litter size (LS) in primiparous and multiparous sows at Ponte Nova region - MG. Seven year-old data were used (1996 - 2003) of eighteen farms you trade. In relation to alimentary diet of the lactic animals, it was compo

9. Prevention of Simian Virus 40 Tumors by Hamster Fetal Tissue: Influence of Parity Status of Donor Females on Immunogenicity of Fetal Tissue and on Immune Cell Cytotoxicity
Fetal tissue from primiparous hamsters prevented simian virus 40 (SV40) tumorigenesis in male hamsters, whereas fetal tissue from multiparous hamsters did not. The parity status of normal (uninoculated) hamsters also influenced the cytotoxicity of their lymphoid cells against tumor cells. Lymph node cells from nonpregnant primiparous and multiparous animals
