Experiments conducted by the authors and their colleagues in the previous five years are summarized. It is concluded that dietary requirements for rumen-degradable, nitrogen (RDN) can be supplied entirely as nonprotein nitrogen (NPN): Also, that supplements of 'NPN and proteins are equally effective in stimulating forage intake, when intake of RDN in the forage is low, provided that intake of N...

This study was carried out to eliminate the toxic effect of soluble oxalate in sugar beet pulp (SBP) by ensiling and adding Ca during determine effects obtained silage on sheep. The based two experiments. For first experiment, laboratory silages were prepared as SBP alone with addition molasses straw at different levels dry matter Ca. After fermentation for 120 days, Fleig scores, physical prop...

The experiment was conducted to investigate the systems of management in small scale cattle fattening programs. The data were collected through an interview schedule from 215 respondents of 24 districts in 52 upazilla who were involved in small scale cattle fattening. In this study out of 215 respondents 70.4% were farmers, 11.7% businessman, 9.18% physicians, 2.04% doctors had own land and 8.8...

Two experiments were conducted to compare the performance and physiological responses of forage-fed beef females supplemented with either a molasses-based (ML) or a citrus pulp-based (CT) supplement. In Exp. 1, BW gain, reproductive performance, and concentrations of blood urea N (BUN), plasma glucose, insulin, IGF-I, and progesterone (P4) were assessed in 60 Brahman x Angus heifers supplemente...

Fifty-eight crossbred yearling heifers (BW = 383 ± 25 kg) were utilized in a completely randomized 2 x 2 factorial arrangement of treatments designed to evaluate the effects of finishing diets containing dried distiller's grains supplemented with degradable intake protein on feedlot performance and carcass characteristics. Dietary treatments contained 10 or 20% dried distiller's grains (DDG) re...

The unique relationship between TDN and CP concentration (low CP relative to TDN) in the whole-plant of 'Floralta' limpograss (Hemarthria altissima) may provide an opportunity for improving cattle performance through protein supplementation. In each of three consecutive years, yearling Brahman x British crossbred steers (initial weight approximately 270 kg) grazed limpograss during the summer a...

Astaxanthin is increasingly attracting commercial interest for its application in the nutraceutical and pharmaceutical industries. This study aimed to produce astaxanthin from molasses with our newly mutated strain of Rhodosporidium toruloides G17 evaluate biological activities produced astaxanthin. To maximize yield, response surface methodology was used so as optimize culture conditions. A ma...

We evaluated the effect of forage quality on response of cattle to supplementation with cooked molasses blocks. In Exp. 1, 175 heifers had ad libitum access to prairie hay (5.2% CP, DM basis). Treatments were a 2 x 3 factorial: supplementation with 0 or 1.96 kg/d of alfalfa DM, and supplementation with no cooked molasses block or with a low-protein or a high-protein cooked molasses block (14.4 ...
