Maturing Pattern for Body Weight, Body Length and Height at Withers of Jamnapari and Boer Goats
The objective of this study was to examine the growth pattern of three size measurements, namely body weight, body length, and height at withers of Jamnapari and Boer goats reared under common semi-intensive environment in Johor, Malaysia. Cross-sectional data of the above measurements of 234 Jamnapari and 312 Boer female goats (age ranged from 6 to 54 months) were used to fit Gompertz and von ...
متن کاملGenetic and uterine effects on survival in mice selected for body weight.
Intraand inter-line transfers of blastocysts were performed between two lines of mice selected for high (H6) and low (L6) body weight at 6 weeks of age. A greater percentage of L6 blastocysts survived to term than did H6 blastocysts (7\m=.\8%,P < 0\m=.\01)and more L6 recipients littered than did the H6 recipients (19\m=.\7%,P < 0\m=.\01).A greater percentage of the mice born to the L6 recipient...
متن کاملGrowth and reproduction in mice selected for rapid body weight gain.
EVERAL investigators have reported the results of selecting for measures of growth rate or body size in mice (GOODALE 1938; MACARTHUR 1944, 1949; FALCONER 1953; RAHNEFELD et al. 1963; ROBERTS 1967). Direct response to selection has been substantial in each of these cases. Litter size has been shown to increase in several of the lines, the increase in the experiment reported by RAHNEFELD et al. ...
متن کاملPrenatal and postnatal maternal influences on growth in mice selected for body weight.
NE method of studying the inheritance of body size in mammals involves the divergent selection of lines for large and small size. A difficulty encountered in this type of experiment is that the differences obtained in body weight or in traits genetically correlated with body size may not be due solely to the genatype for growth rate per se, but may include prenatal and postnatal maternal differ...
متن کاملEffect of selection for litter size and body weight on hormone-induced ovulation rate in mice.
Genetic differences in natural vs hormone-induced ovulation rates were compared in immature female mice from five lines that had undergone long-term single-trait and antagonistic index selection for litter size and(or) 6-wk BW. Lines used were control (K); high litter size (L+); high BW (W+); low litter size and high BW (L-W+); and high litter size and low BW (L+W-). Natural ovulation rate at a...
