Gestation length was affected by maternal lineage (p<0.001). Gestation length was also significantly influenced by the individual mare, age of the mare, year of breeding, month of breeding and sex of the foal (p<0.05). Of the 640 foals born alive at term, 48% were male and 52% female...
Kidding rates were analyzed with respect to occurrence of rainfall during mating and gestation, length of the breeding period, buck:doe ratio, body condition score (BCS) at mating of bucks and does, and month of mating for 4839 indigenous crossbred goats on 46 commercial goat operations under ...
mating and gestation, length of the breeding period, buck:doe ratio, body condition score (BCS; 1 = emaciated and 9 = obese) at mating of bucks and does, and month of mating for 4839 indigenous crossbred goats on 46 commercial goat operations under extensive conditions in northeast Mexico. ...
VEGF-A may increase the growth of placental blood vessels and blood flow to the placenta during gestation in sheep, thus enhancing placental function and allowing the embryo to receive more adequate nutrition, which may be partly responsible for the slightly higher fertility of small-tailed Han ...
The crown-rump length of the fetus in relation to gestational age has been estimated for Saanen and Alpine goat breeds. A crown-rump length of 40 mm is equivalent to 45 days of gestation, 100 mm to 60 days, and 250 mm to 90 days.5 Fetal age also has been estimated for dairy goats...
Low-sulfated chondroitin sulfate-proteogly- cans (CSPGs) have been detected in the placental intervillous space by the end of the third month of gestation14, thus offering a potential anchor point for the IEs-PAM. However, a recent study provides evidences that women in the first trimester of...
Kidding rates were analyzed with respect to occurrence of rainfall during mating and gestation, length of the breeding period, buck:doe ratio, body condition score (BCS) at mating of bucks and does, and month of mating for 4839 indigenous crossbred goats on 46 commercial goat operations under ...
Estrus was carefully observed and each doe was naturally mated twice in the 1st and 2nd day of estrus, thus the first day of estrus was designated as day 0 of gestation. Ultrasound scanning was done using 3.5 MHz transabdominal convex transducer, from d 46-67 for measuring the Crown-Rump ...
