Nitrogen requirement of pregnant gilts.
Eleven Yorkshire x Landrace gravid gilts were used in two Latin square trials to determine the N requirement for pregnancy. Semipurified diets were formulated to be adequate in indispensable amino acids (IAA) and other nutrients. Diets were fed once daily (1.82 kg); L-glutamic acid, corn sugar, powdered cellulose, and soybean oil percentages differed to maintain isocaloric diets. In Trial 1, si...
متن کاملCharacterization of mammary gland development in pregnant gilts.
The purpose of this study was to quantify mammary gland (MG) growth during pregnancy in gilts and to determine the effect of anatomical location on gland growth. Size, composition, and histomorphology of MG were determined during gestation in 29 primigravid gilts. Gilts were allotted randomly to 6 slaughter groups: d 45 (n = 6), 60 (n = 4), 75 (n = 5), 90 (n = 4), 102 (n = 5), and 112 (n = 5) o...
متن کاملAcid phosphatase and leucine aminopeptidase activity in the uterine flushings of non-pregnant and pregnant gilts.
The activities of uteroferrin, measured as acid phosphatase (AP), and an aminoacylpeptidase (AA) were measured in uterine flushings collected from gilts on Days 6, 8, 10, 12, 14, 15, 16 and 18 of the oestrous cycle and pregnancy (N = 37). Changes in AP (P less than 0.05) were associated with day for both specific and total AP in non-pregnant and pregnant gilts. For pregnant and non-pregnant gil...
متن کاملCalcium metabolism in pregnant ewes.
I . A combination of balance and isotope techniques has been used to study calcium metabolism in ten sheep at different stages of pregnancy, and the results have been combined with earlier results obtained during lactation to show the variations in Ca metabolism which occur during the whole reproductive cycle. 2. Transfer of Ca to the foetuses during pregnancy and to the milk after parturition ...
متن کاملPerinatal energy metabolism with reference to IUGR & SGA: studies in pregnant women & newborn infants.
Glucose is the most important fetal energy substrate. During the third trimester increased maternal glucose production and insulin resistance improves fetal glucose availability. Maternal malnutrition, chronic disease and/or placental dysfunction can disturb glucose delivery, resulting in intrauterine growth restriction (IUGR) and an infant born small for gestational age (SGA). Hypoglycaemia is...
