Abstract:
Crossfosterings of three piglets were done on days 1, 4, 7, 10, and 13 of lactation in seven litters. On day 3 of lactation, serum cortisol increased in sows during piglet isolation when compared to before (P = 0.02) or after (P = 0.08) adoption, while GH and prolactin were not affected by isolation (P > 0.1). Mean or maximal values of all hormones were not different after than before adoption (P > 0.1). Key words: Sows, lactation, crossfostering, prolactin, cortisol, growth hormone, nursing

Abstract:
Abstract A series of mouse lines was produced by long-term restricted index selection for divergent rate of growth during early and late postnatal development. The selection program was based on the following treatments: E+ and E- lines were selected to alter birth to 10-day weight gain while holding late gain for both lines constant and a control line was established via random selection. Using embryo transfer and crossfostering methodology, we partitioned postnatal growth for E+, E-, and C lines into progeny genetic, uterine maternal, and nurse maternal components.

Abstract:
Ammonium perchlorate is used as an oxidizer in rocket fuel. It has become a groundwater contaminant, dissociating to ammonium cation and perchlorate anion. The perchlorate ion competes with iodide for uptake into the thyroid, reducing thyroid hormone production. Pregnant Sprague-Dawley rats were given either untreated or perchlorate (1 mg/kg-day) treated drinking water beginning on gestation day 2. One set of control and exposed dams was sacrificed on gestation day 20. The litters from the second set of control and exposed dams were crossed immediately after parturition and were sacrificed at

Abstract:
O experimento avaliou o comportamento da fêmea e dos leitões e o desempenho destes do nascimento ao desmame após as leitegadas serem submetidas a três diferentes manejos de uniformização. A uniformização foi realizada em média 20,1 ± 0,4 horas (amplitude de 14,3 – 24,7 horas) após o parto. Foram formados três grupos: 100B (leitegada composta por 100% leitões filhos biológicos, n= 13), 50BX50A (50% biológicos e 50% adotados, n=13) e 100A (100% adotados, n=13). Todas as leitegadas foram compostas por 11 leitões com peso médio ao nascimento (média: 1454,9 ± 74,6 g; amplitude de 1065 – 1940 g). O

Abstract:
O objetivo desse trabalho foi avaliar a influência da uniformização de leitegadas com leitões de diferentes pesos no consumo alimentar, assim como, nas perdas corporais no período lactacional, no desempenho reprodutivo subsequente de primíparas e o desempenho de suas leitegadas até o desmame. Primíparas suínas foram separadas em 3 grupos: grupo A (n= 31) – leitegadas com 14 leitões leves (1,0-1,2 kg); grupo B (n= 32) – leitegadas com 7 leitões leves e sete leitões com peso intermediário (1,4-1,6kg); e, grupo C (n= 31) – leitegadas com 14 leitões com peso intermediário.
