Annual phenotypic and genetic change of growth pattern for body measurements traits in Holstein females

The experiment to test the selenium impact on body measurements of Lakha, Mushki, Peshaweri and Mianwali varieties of Aseel was conducted. A total of 240 three-weeks-aged birds were selected and divided into four groups, 60 birds per variety (30 + 30 ). These birds were subdivided into three treatment groups A, B, and C with 10 birds from each sex. Birds of group A were fed the diet supplemented with 0.3 mg/kg Se-yeast, B with 0.3 mg/kg sodium selenite and C with No selenium. Improved body measurements in the birds fed Se-yeast included diet were recorded compared to those received sodium selenite incorporated or control diet. Interaction of varieties and selenium sources presented increased breast width, keel length, wing spread, shank length, shank circumference, drumstick length and drumstick circumference in the birds of Lakha got Se-yeast supplemented diet. The study concluded that Se-yeast was more effective in enhancing body measurements of Aseel.

Continuous Evaluation

Optimising heifer growth rates is an essential component of dairy replacement management in order to ensure sustainable heifer replacement stocks. Continuous evaluation of the growth pattern of heifers in a herd may be used to identify particular effects of nutritional management and the environment. Body weight is considered the most useful indicator of a heifer’s growth rate, both in practice and experiment work, along with body measurements reflecting the skeletal growth of heifer. The aims of this research are to investigate: 1) body trait : age relationships, 2) ratio of body measurements to body weight, and 3) to predict body weight based on body measurements of Holstein heifers in Indonesia.

ABSTRACT We investigated the early life growth pattern of pacamã, Lophiosilurus alexandri , a catfish endemic to the rio São Francisco basin, Brazil. Pacamã larvae were kept in a galvanized trough for 29 days after hatching. We collected approximately 10 larvae daily (total number = 285). We obtained from each specimen the total length (independent variable) and 11 other body measurements (dependent variables). We performed linear regressions on the log-transformed data to determine the growth pattern of the body measurements and the respective inflexion point on the growth curves. Except for trunk length, trunk width and yolk sac volume, the remaining body measurements showed a positive allometric growth coefficient up to the respective IP followed by a decrease in the rate of relative growth afterwards. Although trunk width presented a positive allometric growth, no significant inflexion point was detected. The dorsal-ventral head flattening seen in the adult pacamã was quickly expressed in the larvae as indicated by the large allometric growth of head width. Maxillary barbels showed the highest growth rate. The exceptionally high growth rates of eyes and maxillary barbels and the acquired ability to capture prey (as suggested by mouth length growth) strengthened the hypothesis of growth priorities in which the most essential organs develop first.
