The objective of this research was to determine the relationships between the morphological development and in situ ruminally degradable protein (RDP), ruminally undegradable protein (RUP), and microbial protein of two cool season grasses (intermediate wheatgrass and smooth bromegrass) and two warm season grasses (switchgrass and big bluestem). The initial growth of grass tillers grown near Mea...

To maximize digestion by cattle, ruminal microbes require adequate nourishment. For cattle consuming poor-quality forages, nitrogen (N) is the nutrient that is typically most limiting for the microbes (Köster et al., 1996). The total amount of N required by the microbes would minimally be the amount of microbial N flowing from the rumen and to the small intestine, but an additional amount of N ...

the aim of this study was to determine and scrutiny about chemical compounds and microbial load changes of broiler chicks’ diet due to gamma irradiation processing. there were 12 broiler chicks’ diets weighting one kg that including 4 packs from starter period, 4 packs from grower period and 4 packs from finisher period. feeds were irradiated in four doses including 0, 6.7, 7.7 and 8.7 kilogray...

Advantages of pelleted feeds in terms of storage, transportation and lower costs compared to natural fresh feed justified the replacement of artificial feeds instead of natural ones partially on maturation performances. This study comprised nine treatments (with three replications) including control treatment: polychaete worm (Perinereis nuntia), Squid and calf liver (natural feed); T1: pellet ...

The utilization of two crude oil samples of different quality at 4 and 30 C has been studied by using pure and mixed bacterial cultures obtained by enrichment procedures. Growth, emulsification, and utilization occurred readily at both temperatures. The crude oil residue is increased in specific gravity and readily sediments out of solution. A comparison of the chemical analysis of the oils by ...

Three bulls (Zebu x Holstein) fitted with permanent cannuale in the rumen and in the duodenum were used to estimate the efficiency of microbial protein synthesis in the rumen, when the dietary carbohydrate consisted of different proportions of sugar (molasses) and starch (cassava root). Freshly chopped cassava forage was given each day as a source of roughage and protein . The flow of digesta t...

in order to determination of ileum apparent and true digestibility of two samples of poultry by product meal, an experiment was conducted with a total of 60 day-old broiler chicks, ross 308 strain. poultry by-product meal was prepared from two slaughter house in alborz province. samples were sent to laboratory for determination of chemical analysis. the birds received commercial broiler starter...

this research was conducted to estimate the amount of microbial protein synthesis in iranian buffaloes' rumen. four male swamp buffaloes with average live body weight of 140±10 kg were used in this study. four diets of 0 (control diet, 100% forage), 15, 30 and 45% concentrate in a 4 × 4 latin square were tested. the results indicated that by increasing the concentrate level in the diet of swamp...
