1. Melatonin use during pregnancy and lactation: A scoping review of human studies
Objective: The prevalence of sleep disorders during the perinatal period is high and large health administrative database surveys have shown that the use of exogenous melatonin in pregnant populations is quite common, about 4%. Much of the concern about using melatonin during pregnancy and breastfeeding stems from animal research. Thus, the objective of this

2. Transition period produces changes in blood and body composition in mares
RESUMO: Avaliações clínicas e metabólicas são necessárias para o monitoramento de éguas gestantes e lactantes, pois refletem a saúde do animal. A condição corporal da égua pode ser um indicador da eficiência reprodutiva. O estudo objetivou determinar as possíveis variações na condição corporal e metabólica em éguas Mangalarga Marchador dur

3. Environmental enrichment reduces brain excitability in adult rats overnourished during lactation
RESUMO Objetivo: Este estudo analisou se a exposição ao ambiente enriquecido durante a fase juvenil da vida interferiria na atividade elétrica do cérebro de ratos adultos. Além disso, a presente pesquisa também investigou se esse provável efeito na atividade elétrica cerebral poderia ser afetado pela hipernutrição durante a lactação. A eletrofis

4. Ingestive behavior of dairy goats fed diets containing increasing levels of neutral detergent fiber and particle size using multivariate analysis
ABSTRACT. The purpose of this study was to evaluate the effect of interaction between increasing neutral detergent fiber content and particle sizes on ingestive behavior of dairy goats. Forty-eight lactating, multiparous Saanen and Alpine goats, with average milk production of 1.4 ±0.57 kg d-1, around 60th ±12 day of lactation were distributed in a 3 x 4 f

5. Milk production in Saanen goats treated with repeated low doses of intermediate-release insulin during early lactation
RESUMO: O objetivo do estudo foi avaliar o efeito da administração de insulina sobre a resposta produtiva de cabras Saanen durante a lactação inicial. Dez de vinte fêmeas adultas foram sujeitas à administração subcutânea de repetidas e baixas doses de insulina de liberação intermediária aos 2, 9 e 14 dias pós-parto. A produção de leite foi me

6. Dietary level of cull pinto beans on animal performance, digestibility, and energy balance of pregnant-lactating hair ewes
ABSTRACT The objective of this study was to evaluate the effect of three levels of cull pinto beans (CPB) on animal performance, energy balance, and digestibility of hair ewes during pregnancy-lactation. One hundred and sixty-eight Pelibuey ewes were used (105 multiparous and 63 primiparous). Seven ewes of each type were randomly assigned to each of the 24 p

7. Predicting post-absorptive protein and amino acid metabolism
ABSTRACT Sustainable production of adequate quantities of food to support a growing human population is a worldwide goal. Under current feeding conditions in the United States, dairy cattle convert dietary nitrogen to milk nitrogen with 25% efficiency. The remaining 75% is excreted, which contributes to air and water quality problems and reduces economic per

8. Effect of the addition of protected fat from palm oil to the diet of dairy sheep
ABSTRACT The objective of this study was to evaluate the effect of protected fat from palm oil on body weight and milk production and composition of lactating Lacaune ewes. Four treatments (0, 20, 40, and 60 g kg−1 as fed) of protected fat from palm oil were used to feed nine animals in each group. Isoproteic and isoenergetic diets were formulated and adju

9. Genetic parameters for type score traits and milk production in Brazilian Jersey herds
ABSTRACT This study aimed to estimate the heritability coefficients for ten functional type traits and milk production in the Jersey breed in Brazil, besides the genetic and phenotypic correlations between them. The present study utilised data from 1,567 records of linear type traits, including stature (ST), body depth (BD), loin strength (LS), rump width (R

10. Perinatal effects of scorpion venoms: maternal and offspring development
Abstract Scorpion envenomation is a public health problem, especially in tropical and subtropical countries. Considering the high incidence of scorpionism in some areas, pregnant women and nursing mothers may be possible victims. Scorpion stings alter the release of neurotransmitters and some cytokines. These mediators act as organizers and programmers in th

11. Bone turnover markers in sheep and goat: A review of the scientific literature
ABSTRACT Bone turnover markers (BTMs) are product of bone cell activity and are generally divided in bone formation and bone resorption markers. The purpose of this review was to structure the available information on the use of BTMs in studies on small ruminants, especially for monitoring their variations related to diet, exercise, gestation and metabolic l

12. Effects of excess maternal thyroxin on the bones of rat offspring from birth to the post-weaning period
ABSTRACT Objective To evaluate, in rat offspring, bone changes induced by excess maternal thyroxin during pregnancy and lactation, and to assess the reversibility of these changes after weaning. Material and methods Twenty Wistar rats were distributed in two groups, hyperthyroid and control, that were treated daily with L-thyroxin (50 mcg/animal) and pla
