As a result of the cost of grains, the replacement of grains by co-products (i.e. DDGS) in feedlot diets is a common practice. This change produces diets that contain a lower amount of starch and greater amount of fibre. Hypothetically, combining feed grade urea (U) with slow release urea (Optigen) in this type of diet should elicit a better synchrony between starch (high-rate of digestion) and...

Two experiments were performed to evaluate the effects of different levels of supplementation with a 50:50 (as-fed) mixture of molasses:crude glycerol on animal performance, total tract digestibility of nutrients, and ruminal in situ degradability of nutrients in beef heifers and steers consuming Tifton 85 Bermuda grass (Cynodon spp.) hay. For Exp. 1, 24 Angus crossbred heifers (380 ± 31 kg BW)...

Pineapple waste silage (PAS) is an abundant agro-industrial by-product characterized by its high fiber content posing a potential feed value as roughage for ruminants. Studies on supplementation with proteolytic enzyme (PE) will help extend utilization alternative nutritive source cattle nutrition. Thus, this study aimed to determine the in vitro nutrient degradability and fermentation characte...

The study aimed to evaluate the impact of black rice and purple corn extracted residue (BPER) on feed intake, nutrient digestibility, growth performance, antioxidant activity in male dairy cattle. after extraction anthocyanin from contains phenolic acids. Several researchers found that anthocyanins acids had antimicrobial functions animals. Sixteen cattle (with average body weight 160 ± 10.6 kg...

this study was conducted to determine the nutritive value of fresh and ensiled whole and partly stoned olive cake (oc) with or without molasses i.e., 0 and 50 gkg-1 on fresh basis. dry matter (dm), organic matter (om), crude protein (cp), neutral detergent fiber (ndf), acid detergent fiber (adf), lignin (sa), ether extract (ee), water soluble carbohydrates (wsc), and total phenols (tph) of all ...

Two digestion experiments and an in situ nylon bag experiment were conducted to determine the correlations between chemical composition, ruminal in situ degradation kinetics and OMI, and OM and CP digestibilities of diets in wethers fed forages of varying nutritive value without and with protein supplementation. Wethers were fed ground corn crop residues, oat-berseem clover or alfalfa hay in th...

This study was conducted to compare the effects of mannanoligosaccharides (MOS) and antibiotics as a dietary supplement on ADG, ADFI, G:F, and feed nutrient digestibility of rabbits during the fattening period, as well as on carcass traits and meat quality. A total of 512, sixty-day-old hybrid Hyla rabbits were randomly divided into 4 treatment groups based on BW and sex. The 4 treatment groups...

A study was conducted with the objective to identify adaptable and chemical composition of Lablab varieties. Three Beresa-17, Gabis-55 Local variety +were tested in randomized complete block design (RCBD) three replications. The result revealed that date maturity significantly (p 0.05) differ among analyzed compositions indicated, Beresa-17 had highest Organic matter (OM), crude protein (CP), n...
