1. Lactation curves and economic results of Saanen goats fed increasing dietary energy levels obtained by the addition of calcium salts of fatty acids
The objective of this study was to evaluate the use of calcium salts of fatty acids (CSFA) to increase the dietary energy levels for Saanen goats and their effects on the lactation curve, dry matter intake, body weight, and economic results of the goats. Twenty multiparous goats, weighing an average of 63.5±10.3 kg, were randomly assigned to one of four tre

2. Prenatal lipopolysaccharide increases maternal behavior, decreases maternal odor preference, and induces lipopolysaccharide hyporesponsiveness
The present study investigated whether late maternal inflammation disrupts the mother/pup interaction, resulting in long-lasting effects on pup behavior and alterations in biological pathways, thereby programming prepubertal behavior and the pups' inflammatory responses after bacterial endotoxin treatment. Female rats received 100 μg/kg lipopolysaccharide (

4. Respostas fisiológicas, produtivas e comportamentais de ovelhas Santa Inês submetidas a manejos considerados estressantes e desempenho de seus cordeiros / Physiological, productive and behavioral responses of Santa Inês ewes subjected to stressful managements and performance of their lambs
With the objective to evaluate the susceptibility of ewes to stress and its relation to milk production, 50 Santa Ines females were submitted to four stressful challenges during two successive lactations (1: standard physiological stress through ACTH administration; 2: weaning; 3: first milking; 4: change of milker). In ewes, it were evaluated the physiologi

5. Environmental and genetic effects on the lactation curves of four genetic groups of crossbred Holstein-Zebu cows
The objective of this study was to evaluate the effects of genetic group and environmental factors, including farm of origin, season of calving and lactation number, on the individual lactation curves of 1,010 Holstein-Gyr, Guzerat-Holstein, Holstein-Nellore, and Holstein-Zebu F1 cows on the experimental farms of the Agricultural Research Company in Minas Ge

6. Evaporative cooling for lactating sows under high ambient temperature
Two experiments were conducted to evaluate the evaporative cooling of the air at farrowing on the performance of lactating sows under high environmental temperature conditions in the Central West region of Brazil. One hundred and forty-four lactating sows - 46 of first and second farrowing (experiment I) and 98 from the third to eighth farrowing (experiment

7. Avaliação da eletroestimulação nervosa transcutânea para alívio da dor de contração uterina pós-parto durante a amamentação: ensaio clínico randomizado / Assessment of transcutaneous electrical nerve stimulation to relieve the painful postpartum uterine contractions during breastfeeding: a randomized clinical trial
During breastfeeding occurs the release of oxytocin for milk ejection, that cause uterine contractions associated with painful process. The transcutaneous electrical nerve stimulation (TENS) is a physical therapy resource, which aims to pain relief. The main objective of this study was to evaluate the effectiveness of TENS to relief of painful uterine contra

8. Reproductive and productive performance of lactating sows fed diets supplemented with vegetable oil or tallow / Efeito da adição do óleo de soja, óleo de linhaça, óleo de coco babaçu e sebo bovino nos parâmetros produtivos e reprodutivos de fêmeas suínas em lactação
Twenty-four Dalland C40 sows were used in one experiment to study the effect of dietary vegetable oil or tallow on productive and reproductive parameters. All sows were fed a corn-soybean meal diet supplemented with 8% soybean (T1), linseed (T2), coconut (T3) oil or tallow (T4) from day 100 of gestation and throughout the lactation period. Sow initial weight

9. Longitudinal profiles of fecal steroids concentrations in jaguarundi?s females (Herpailurus yagouaroundi, Lacépède, 1809) / Avaliação longitudinal das concentrações de esteróides fecais em fêmeas de gato-mourisco (Herpailurus yagouaroundi, Lacépède, 1809)
The aim of this study was analyze the ovarian cycle of captive jaguarundi (Herpailurus yagouaroundi) trough fecal steroid. Radioimmunoassay (RIA) was used for the measurement of estradiol, progesterone and cortisol metabolites in feces. Fecal samples were collected five days per week from eight females kept at Fundação Parque Zoológico de São Paulo durin

10. Dopaminergic modulation of grooming behavior in virgin and pregnant rats
Dopamine receptors are involved in the expression of grooming behavior. The pregnancy-induced increase in self-licking observed in rats is important for mammary gland development and lactation. This study focuses on the role of dopamine receptor subtypes in grooming behavior of virgin and pregnant female rats. General and mammary gland grooming were measured

11. Lactation and cancer risk: is there a relation specific to breast cancer?
Relations between previous lactation experience and risks of cancer of the breast and other sites were investigated after follow-up of 50,274 parous women from 1961 through 1980. Among women with complete information on lactation, 5102 developed cancer and, of these, 1136 were diagnosed with breast cancer. Analyses of associations with mean duration of lacta

12. Effect of a lactation nurse on the success of breast-feeding: a randomised controlled trial.
An evaluation of a lactation nurse by means of a randomised controlled trial is described. The lactation nurse was employed to assist, support, and encourage mothers during the early weeks after parturition in hospital and at home. All mothers who breast-fed at least once were entered into the trial. Altogether 649 mothers were interviewed 12 months later to
