| O objetivo deste trabalho foi verificar se a ingestão diária de diferentes quantidades de lisina digestível, pelas fêmeas suínas primíparas em lactação, influencia o desempenho produtivo, reprodutivo e o perfil sangüíneo dessas matrizes. Utilizaram-se inicialmente 50 porcas primíparas em lactação, distribuídas em 5 tratamentos (10 animais por tratamento), correspondendo a 0,88; 0,99; 1,04; 1,08 e 1,24% de lisina digestível na ração. Utilizou-se delineamento experimental de blocos ao acaso, sendo cada matriz considerada uma unidade experimental. Os resultados foram avaliados através de modelos estatísticos de análise de variância, utilizando-se a regressão linear ou quadrática conforme o melhor ajuste. As variáveis de desempenho das matrizes (perda de peso,... |

| Sows produce a larger number of fetuses than before and these fetuses possess genetic potentials to grow faster than before. Recent comparison shows that a porcine fetus is 40% heavier than 40 years ago. Thus the nutritional management of sows has been updated to reflect these genetic changes. Our recent study quantified nutritional needs for sows to support the growth of fetuses and mammary glands during gestation. Amino acid needs for fetal growth and mammary growth during late gestation (d 70 to farrowing) significantly greater than those needs during early gestation (until d 70). Considering these increases, daily requirement of true ileal digestible Lys for a primiparous sows increases from 7 g (until d 70) to 15 g (d 70 to farrowing). Required... |

| The main objectives of this study were to verify the relationship among body condition at parturition, decrease of backfat thickness and weight during the lactation and the interval from weaning to oestrus of sows. It was performed with 10 gilts and 10 fifth, sixth and seventh parity Camborough sows. The average breeding age and weight of the gilts were respectively 231 days and 149.5 kg. During lactation all females were fed a wet diet (3.34 Mcal/kg, 17% CP), ad libitum. The average daily food consumption was 5.233 for gilts and 5.721 kg for multiparous sows. Ultrasonic measurements of backfat at the P2 site were recorded on day 6 before and days 2, 7, 14, 21 and 25 after parturition. Body weight was recorded on the same dates, except the day before... |

| ABSTRACT: Fixed-time artificial insemination (FTAI) is a reproductive technology that aids in obtaining an appropriate time to perform single artificial insemination (AI), thus reducing the number of inseminations per sow bred. FTAI protocols can either be based on estrus detection or day of weaning, aiming to synchronize ovulation using ovulation inducers. The protocols involving estrus detection usually employ porcine luteinizing hormone (pLH) as an inducer and, in general, satisfactory reproductive performance is observed. For protocols based on weaning day, the main hormone used is analog of gonadotropin-releasing hormone such as triptorelin and buserelin. Regardless of the protocol, the number of piglets born is usually not affected by FTAI. However,... |
