PigThis study is based on 12708 first-parity and 7062 second-parity Yorkshire litters from Swedish nucleus herds; and on 1037 first-parity Yorkshire litters from an experimental herd. Gestation length was analysed together with litter size, piglet mortality and average piglet growth rate. A sire鈥...
Lesions of the hypothalamic region of the fetus and length of gestation in the guinea-pig 来自 Semantic Scholar 喜欢 0 阅读量: 16 作者:CALIGARIS, L.,DONOVAN, B. T. 摘要: A lesion was placed in the hypothalamic region of the brain of one fetus in each of 25 guinea-pigs on days 39-...
Either a single factor or a great number of minor factors, all culminating at or near one date, determine the length of gestation. Several minor variations are known: inman, gestation for males is three to four days longer than that for females; and in cattle, bulls are carried about one...
In swine, longer gestation length is positively correlated with piglet survivability, however, stillborn piglets are more frequent. Heavier birth weights also normally accompany longer gestation lengths. The objective of the study was to evaluate if gestation length would have a negative impact on numbe...
This combination of viral infection and hypothyroidism is coincident with the suppression of cell division across multiple organs [16], but despite an identical gestational age and length of disruption between studies, the organs most severely impacted by PRRSV-induced hypothyroidism were the HRT and ...
Of course, the gestation length of a pig can vary due to factors such as age, environment, the time of year, and breed. Whether you have apet pig, like a potbelly pig where the gestation period is about 115 days, or if you live with a pig on a farm, keep in mind these numbers ...
length and diameter at D16 (gestation period of 19-21 days). Maternal genotype also had a strong effect on placental expression of transporter and cell lineage genes. In cattle, Mansouri-Attia etal. [17] showed that the conceptus derived from in vitro fertilization (IVF) or somatic cell ...
The gilts were killed, and the length of the uterus measured and corpora lutea (CL) and fetuses were counted. The length of one uterine horn at 150 days of age was 70 cm with a range of 47–110 cm. At 10 days after first estrus, length had increased to a mean of 141 cm with a...
Placental length and weight, fetal length and weight, and allantoic fluid volume were greater (P < 0.05, 0.001, 0.05, and 0.001, respectively) in intact than in UHOX gilts. P 4 concentration was lower (P < 0.001, 0.002, and 0.001 at Days 50, 70, and 90, respectively) in the ...
