1. Comparison of predictive performance of data mining algorithms in predicting body weight in Mengali rams of Pakistan
ABSTRACT The present study aimed at comparing predictive performance of some data mining algorithms (CART, CHAID, Exhaustive CHAID, MARS, MLP, and RBF) in biometrical data of Mengali rams. To compare the predictive capability of the algorithms, the biometrical data regarding body (body length, withers height, and heart girth) and testicular (testicular lengt

2. Relationship of post-weaning growth and age at puberty in crossbred beef heifers
ABSTRACT This study was intended to evaluate body size structure and growth parameters of crossbred heifers fed at four nutritional levels to achieve puberty earlier. Animals were classified depending on their level of crossing between Nelore and Hereford and subjected to four nutritional levels (kg day−1) as follows: 0.5 (light; n = 32), 0.75 (medium; n =

3. Influence of environmental factors on ponderal performance and morphometric characteristics of lambs of different genetic groups from birth to weaning
The objectives of this work were to evaluate the environmental effects (age of dam, type of birth and sex of lamb) and genetic groups (Hampshire Down and Ile de France, ½ and ¾ Hampshire Down, Ile de France and Suffolk, and ½ Texel) on performance and morphometric characteristics (height, length and heart girth) of lambs; to test regressions to predict li

4. Performance and carcass traits of Santa Inês lambs finished with different sources of forage
The objective of this study was to evaluate performance and biometrics of lambs fed different sources of forage. Twenty-four six-month-old Santa Inês female lambs were randomly allocated to four experimental diets and housed in individual stalls. They weighed on average 26.35±0.20 kg. The diets were coast cross hay (HAY), cassava hay (CAS), dehydrated by-p

5. Effect of environmental factors on performance of purebred and crossbred Santa Inês lambs from birth to 154 days of age
The objectives of this study were to evaluate the environmental effects (age of dam at lambing, type of birth and sex of lamb) and genetic groups (Santa Inês and ½ Santa Inês) on weight and morphometric measurements (heart girth, body length and height) of lambs; to test linear and allometric regressions to predict the weight through the measurements; and

6. Silagem de colostro: caracterização do perfil de fermentação anaeróbia e desempenho de bezerros leiteiros / Colostrum silage: dynamics of anaerobic fermentation and dairy calves performance evaluation
The objective of this study was to characterize the fermentative dynamic of bovine colostrum, under anaerobic condition, and determine the nutritional value, as well as evaluate dairy calves´ performance receiving colostrum silage as liquid diet. In the first experiment, bovine colostrum from second and third milking was fermented at room temperature in PET

7. Variação nas medidas corporais e desenvolvimento do trato reprodutivo de novilhas de corte recriadas para o acasalamento aos 18 meses de idade
O objetivo deste estudo foi avaliar os efeitos do ganho de peso no período de recria, dos 13 aos 19 meses de idade, em algumas medidas de desenvolvimento corporal de novilhas de corte de reposição, da raça Hereford, mantidas em pastagem nativa. O período experimental foi compreendido entre 15/11/2002 e 23/04/2003. Os tratamentos foram três taxas de gan

10. Body fat distribution in the Finnish population: environmental determinants and predictive power for cardiovascular risk factor levels.
STUDY OBJECTIVE--The aim was to examine (1) whether health habits are associated with body fat distribution, as measured by the waist/hip girth ratio, and (2) to what extent environmental factors, including anthropometric characteristics, explain the variability in levels of cardiovascular risk factors. DESIGN--The study was a population based cross sectiona
