Weaning weight, preweaning daily gain and 205-day weight of Hungarian Fleckvieh calves (n=8 929, bulls =4 539, heifers =4 390) born from 232 sires between 1980 and 2003 were examined. Variance, covariance components and heritability values and correlation coefficients were estimated. The effect of the maternal permanent environment on genetic parameters and breeding values were examined. Two an...

the aims of this research were to estimate of genetic parameters for pre-weaning traits and lamb survival in iran-black sheep. for this purpose 6344 records for birth weight (bw) and lamb survival (ls) and 5264 records for weaning weight (ww), average daily gain (adg) and kleiber ratio (kr) were available, which collected by abbasabad animal breeding and rearing station, over the period from 19...

The objectives of the present study were to investigate the effects of breed, sex, parity, year of birth and season of birth on birth weight, weaning weight and yearling weight recorded on 713 calves born between 1996 and 2008. The data included offspring from five local cattle breeds (Dhanni, Lohani, Dajal, Red Sindhi, Cholistani) and crossbreds (Holstein or Jersey crosses) maintained at Baran...

In a 5-week study, 120 crossbred weaning pigs (age 4 weeks) were used to examine the effects of an additional Fe-injection and immunization moment on the growth and humoral immune response. Pigs were allotted to one of eight treatments based on body weight and litter origin. Factors included: (1) single intramuscular injection (day 3 after birth) vs. double intramuscular injection (days 3 and 2...

Two studies were performed to determine whether there were behavioural or productive differences arising from two contrasting weaning practices for red deer; proximate vs. distant separation of dams and calves. In Experiment 1, 80 calves across two replicates were used. For each replicate, calves were separated from their mothers, weighed and allocated to one of two treatments (n=20 calves), ei...

OBJECTIVES To determine the association between weaning practice and malnutrition among infants. METHODOLOGY This descriptive cross-sectional study was conducted at Department of Pediatrics in Saidu Group Teaching Hospitals, Swat, with 133 participants selected using a non-probability consecutive sampling technique. Infants both genders, aged one year or younger, Pakistani nationals mentally so...

Angus (A), Brown Swiss (S) and A X S reciprocal F t (AS) dams were mated to A, S and AS (also reciprocal F 1 ) sires resulting in nine breed groups of progeny with varying proportions of Angus and Brown Swiss breeding. Breed group of dam and of sire significantly influenced birth weight, preweaning daily gain, weaning weight, 205-d weight, condition score and frame size. The means for birth wei...
