Analyses for lens sugar alcohols, fructose, glucose, ATP, dry weight, hydration, and extracellular space were made before and after the appearance of mature diabetic and galactose cataracts. The appearance of mature cataracts in galactose-fed rats is associated with a marked and sudden decrease in the level of lens sugar alcohol, ATP, and dry weight, and an increase in lens hydration and extrac...

background: most studies on anabolic-androgenic steroids abuse have been done in adult rats, but few data are available to immature. objective: this study was conducted to assay the effect of nandrolone decanoate (nd) on the testis and testosterone concentration in male immature rats compare with mature ones in short and long time. materials and methods: 40 mature rats were divided into 4 group...

Linear functions of body weight and condition score at weaning and 18 mo of age were used to predict the mature weight (A) and maturing rate (k) parameters of an asymptotic growth model of Angus cows at the Subtropical Agricultural Research Station, Brooksville, FL. From 1981 through 1988 a heavy-mature-weight line (Line A) and a rapid-maturing line (Line K) were selected based on predicted A a...

Data from the first four cycles of the Germplasm Evaluation Program at the U.S. Meat Animal Research Center (USMARC) were used to investigate genetic relationships between mature weight (MW, n = 37,710), mature weight adjusted for body condition score (AMW, n = 37,676), mature height (HT, n = 37,123), and BCS (n = 37,676) from 4- to 8-yr old cows (n = 1,800) and carcass traits (n = 4,027) measu...

The biosynthesis and processing of cellulase from ripening avocado fruit was studied. The mature protein is a glycoprotein, as judged by concanavalin A binding, with a molecular weight of 54,200. Upon complete deglycosylation by treatment with trifluoromethane sulfonic acid the mature protein has a molecular weight of 52,800 whereas the immunoprecipitated in vitro translation product has a mole...

Changes in the cellularity of various adipose tissues in growing cattle were analyzed. Fifty male cattle were slaughtered between 15 and 65% of mature weight. The whole adipose mass, separated by dissection, was divided into three parts: subcutaneous, intermuscular, and internal adipose tissues. Lipid content, cell size and distribution, as well as cell number of these three parts were determin...

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 ...

the aim of this study was to investigate the effect of reducing metabolizable protein with rumen-protected lysine and methionine in diet during the last 5 weeks of gestation on performance and blood parameters of afshari ewes and lambs. twenty five mature (once lambing) ewes in a unbalanced complete randomized design fed with diets containing low metabolizable protein but containing rumen-prote...
