1. Dietary iron chelate for sows and effects on iron supplementation in piglets
Abstract: In order to evaluate iron chelate in diets for sows during gestation and lactation and its effects on iron supplementation for piglets, a total of 50 pregnant sows in the third parity order were distributed according to a randomized block design with two treatments: diet without iron chelate supplementation (n=20); diet supplemented with 0.15% of i

2. REPRODUCTIVE EFFICIENCY AND BEHAVIOR OF PREGNANT SOWS HOUSED IN CAGES AND COLLECTIVE PENS WITH OR WITHOUT BEDDING
ABSTRACT This study aimed to evaluate the effect of wood shaving bedding on pregnant sows under two housing conditions. Sixty-four animals were distributed into four treatments, each treatment included 54 sows split into three replicates. A 2 × 2 factorial design was used (two types of housing, collective pens (CP) and combined housing (cages + CP [CCP]); a

3. EFFECT OF AUDITORY ENRICHMENT (MUSIC) IN PREGNANT SOWS WELFARE
ABSTRACT Studies have shown that the benefits from music can improve the welfare conditions of laboratory, pet and production animals. The study aimed to evaluate the influence of music (Antonio Lucio Vivaldi compositions) on behavior aspects (position, activity, stereotypes, social and agonistic behavior) and physiological responses (respiratory rate and re

4. The effect of supplementing sow and piglet diets with different forms of iron
ABSTRACT The objective of this study was to evaluate the effect of chelated iron supplementation on gestating and lactating sows and on their suckling and weaned piglets. Reproductive traits, piglet performance, hematological parameters, and the iron concentrations in colostrum, milk, and stillborn livers were measured. Ninety-six sows were subjected to one

5. PRODUTIVIDADE E BEM-ESTAR DE PORCAS GESTANTES ALOJADAS EM BAIAS COLETIVAS COM PISO DE CONCRETO OU CAMA SOBREPOSTA / PRODUCTIVITY AND WELFARE OF SOWS PREGNANT HOUSED IN COLLECTIVE PENS WITH CONCRETE FLOOR OR DEEP BEDDING
O objetivo desta dissertação foi estudar através de meta-análise os níveis de cortisol e a produtividade de porcas gestantes e através de um estudo a campo os efeitos do sistema de alojamento sobre o comportamento e a produtividade de porcas gestantes. A meta-análise foi composta por 22 artigos publicados entre 1996 a 2010, totalizando 170 tratamentos

6. Effects of dietary mineral bioplex in pregnant and lactating sow diets on piglet performance and physiological characteristics
A total of thirty-six Landrace × Large White sows were inseminated with semen of Large White boars and studied in late pregnancy (30 days pre-partum) and lactation phases to determine the effects of trace mineral supplementation in organic (bioplex) and inorganic forms at two levels of supplementation (1 and 2 kg/t) on the reproductive performance of the fe

7. Impactos de peso da fêmea no último mês de gestação sobre a ocorrência de leitegadas desuniformes e influência dos parâmetros fisiológicos do leitão ao nascimento sobre seu desempenho pós-natal / Impact of sow’s weight in late gestation on the occurrence of non uniform litters and consequences of piglets physiological parameters changes at birth and postnatal performance
A suinocultura moderna tem se destacado pelos altos índices produtivos alcançados. Muito disso se deve à intensa tecnificação, fazendo com que as linhagens de fêmeas suínas fossem melhoradas geneticamente tornado-as hiperprolíficas. Este aumento possibilitou uma melhor produtividade e maior ganho econômico. Entretanto, houve o surgimento de problema

8. Avaliação do desempenho de Suínos Alimentados com Mananoligossacarídeos (MOS) / Effects of mannan oligosaccharides on gilts and litters performance
The present study evaluated the effects of mananoligossacarides (MOS) as a feed additive on the performance of primiparous sows in late gestation and lactation, as well as on performance and health status of their progeny up to 65 days of age. The experiment was conducted in the Laboratory of Swine Research (FMVZ/USP) Pirassununga SP. For this purpose a comp

9. Toxicity of cyanide in swine: evaluation of perinatal effects / Toxicidade do cianeto em suínos. Avaliação dos efeitos perinatais
Cyanide and cyanogenic compounds are ubiquitous in nature and widely studied in toxicology. Long-term cyanide exposure has been associated to development of goiter, pancreatic diabetes, and several neurological diseases in humans and animals. However, the exact mechanism involved in induction of these diseases are not fully elucidated. It is believed that th

10. Epitope specificity of protective lactogenic immunity against swine transmissible gastroenteritis virus.
The epitope specificity of the protective immune response against swine transmissible gastroenteritis (TGE) has been investigated by using circulating and secretory antibodies. This study was carried out with sows vaccinated with TGEV or the antigenically related porcine respiratory coronavirus (PRCV). TGEV vaccination of sows resulted in greater lactogenic

11. Lactose in plasma during lactogenesis, established lactation and weaning in sows.
The concentration of lactose in plasma was determined in different sows at all phases of their reproductive cycle and related to the compositional changes in mammary secretion during lactogenesis, established lactation and weaning. Lactose was present in low concentrations (3-4 microM) in the blood of virgin sows and pregnant sows up to 107 days of gestation

12. Immunoglobulin Classes of Antibodies in Milk of Swine After Intranasal Exposure to Pseudorabies Virus or Transmissible Gastroenteritis Virus 1
Experiments were conducted to evaluate whether infection of the respiratory tract of pregnant swine with pseudorabies (Pr) virus would induce the secretion of immunoglobulin A (IgA) antibodies in their milk as was observed after enteric infection with transmissible gastroenteritis (TGE) virus. The immune response of sows to Pr virus inoculated intranasally a
