Estimation of feed intake (FI) for individual animals within a pen is needed in situations where more than one animal share a feeder during feeding trials. A partitioning method (PM) was previously pu...
The aim of this study was to evaluate interrelationships of body weight and bone weight and densitometric properties of the tibiotarsus in White Koluda Geese (W31) in the post-hatching period. The stu...
The objective of the present study was to determine the association between the uterine size and age, body weight, growth rate, and reproductive status in Landrace × Yorkshire crossbred gilts. Genital...
A retrospective, observational study comprised analyses of individual cow records from a computerised herd management system. Production, body weight, and reproduction data were collected between ...
We investigated 3 985 individually housed hens of five original laying lines of two breeds RIR and BPR. The proportion of abnormal eggs out of the eggs laid before the age of 240 days ranged between 7...
This study was carried out to investigate the effect of different body weight groups (light (L) = 1 400–1 500; medium (M) = 1 500–1 600 and heavy (H) = 1 600 < g) on performance and egg quality traits...
6 508 bulls of dual-purpose cattle at performance-test stations were weighed at intervals of 30 days from birth to 420 days. After all editing a total of 74 558 weight records were available. Live wei...
Genetic parameters of production and reproduction traits were estimated using 39,926 records from 5,860 individual progenies of 163 sires and 1,558 dams. The data were collected at Makuie Sheep Breedi...
Data on age and body weight at breeding, parity, previous litter size, days open and some descriptive body linear traits from 389 meat-type, prolific Black Bengal goats in Tripura State of India, were...
Forty-five Hisex commercial layers and forty-five local Saudi breed layers were used to determine the acceptable limit of short-term water restriction in the late phase of production, when the problem...
A selection experiment for reduced residual feed intake (RFI) in Yorkshire pigs consisted of a line selected for lower RFI (LRFI) and a random control line (CTRL). Longitudinal measurements of daily f...
The purpose of the current study was to examine the influence of different maternal nutrition treatments during pregnancy on body weight, muscle fiber number, carcass traits, and pork quality traits o...
The present study aimed to investigate the effects of maternal factors on body weight at hatching (day-old) and at six weeks of age in a commercial broiler line. A total of 6,765 records on body weigh...
It is important to know the limit of artificial selection for efficient animal production. The aim of this research was to examine whether the selection for small body weight in Japanese quail has rea...
The development of the commercial broiler industry during the last half of the 20th century has seen dramatic changes in growth, feed efficiency, and yield. In this paper we extracted results from thr...
