Total mixed rations containing conventional forage sorghum, brown midrib (bmr)-6 forage sorghum, bmr-18 forage sorghum, or corn silage were fed to Holstein dairy cows to determine the effect on lactation, ruminal fermentation, and total tract nutrient digestion. Sixteen multiparous cows (4 ruminally fistulated; 124 d in milk) were assigned to 1 of 4 diets in a replicated Latin square design wit...

Grain sorghum silage tannin content effect was evaluated on milk production and chemical composition of Argentinean Holstein bred cows, and it are described dry matter (DM) and crude protein (CP) in situ digestion parameters and effective degradability. The base diet was constituted by alfalfa pasture, maize silage, and a protein – mineral supplement, differing in three treatments based on high...

The present study was aimed at assessing the ingestive behavior of ¾ Zebu × Holstein heifers confined to different levels of substitution of sorghum silage by marandu grass silage. Twenty heifers were used with initial average weight of 346.25 kg, divided into completely randomized experimental design with 5 repetitions and the following treatments: treatment 1) roughage fraction of the diet co...

From preliminary studies of the feeding value for mediumwool Merino wethers of various samples of sorghum silage, the following points emerge : 1. Mature silage, in addition to being moderately unpalatable, had a low level of digestible protein, a variable digestible crude fibre and a high mineral content. In spite of the latter, most sheep had negative mineral balances. A feature of the ash co...

Two experiments were carried out to determine the nutritive value and to evaluate the performance of growing rabbits fed on isoenergetic diets containing high moisture sorghum silage grain with low or high tannin levels. In the digestibility assay (experiment 1), the nutritive values of silages were determined with 30 New Zealand White rabbits, 15 males and 15 females, 55 days old, allotted in ...

The effects of increasing grain content of sorghum silage at the soft dough or the mature stages on nutrient digestibility, rate of passage and ruminal characteristics were investigated. A hetero-yellow grain sorghum (WAC 710DR) was harvested at the soft dough and the mature stage. Conventional sorghum silage was harvested by harvesting only the material more than 12 cm above the ground, high-e...

the chemical and fermentative parameters of three fresh forages and silages of sorghum including sweet, pegah and speedfeed varieties were compared with corn using in vitro method, also degradability coefficients of forages and silages were determined by in situ method. forages were planted in the same condition and harvested in soft dough stage, then ensilaged in four replicates for each time ...

OBJECTIVE The effects of lactic acid bacteria (LAB) and cellulase enzyme on fermentation quality, microorganism population, chemical composition and in vitro gas production of sorghum silages were studied. METHODS Commercial inoculant Lactobacillus plantarum Chikuso 1 (CH), local selected strain Lactobacillus casei (L. casei) TH 14 and Acremonium cellulase (AC) were used as additives in sorgh...

Fibrolytic enzymes and microbial inoculants have the potential to improve the value of sorghum feedstuff and feedstock. An experiment was conducted to determine nutritive value, ensiling characteristics, and in situ disappearance kinetics of 4 sorghum (Sorghum bicolor L.) silage varieties: Dairy Master BMR (DBMR; brown midrib; Richardson Seed, Vega, TX), PS 747 (PS; photoperiod sensitive; Pogue...
