feed between growth rate, carcass composition, intake, feed conversion ratio and income in four biological types of cattle (1)
To determine the effect of different doses of:
– ADIMIX C (0, 500, 1000 g/ton )
– ADIMIX 30 COATED 1500 g/ton in the prestarter and starter
– Prestarter contained 5 kg/ton Ultracid Lac Plus Dry.
– Starter contained 3 kg/ton Ultracid Lac Plus Dry.
• To determine the equivalence of ADIMIX Coated 30%
to ADIMIX C
• To determine the optimal dose in the prestarter/starter
To obtain the best practical diet (in terms growth rate, survival rate, feed conversion ratio and water quality) which can replace the Vital feed (an expensive feed for Kuruma prawn) and trash fish under laboratory conditions.
1. Conduct Experiment 1: to test three practical diets: a) the "best" diet from Vu-anh Tuan' s PhD research; b) Diet a) plus additives (e.g., vitamins and minerals); and c) Diet b) with further supplement (e.g., vitamins and minerals plus mixed enzymes).

The results showed that weight gain (WG), showed that fishmeal protein replacement levels had significant effects on fish weight gain (WG), specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER), economic conversion ratio (ECR) (P 50 % protein (Công ty EWOS) trong đó bột cá được xem là nguồn protein chủ yếu trong thức ăn. Tuy nhiên trong những năm gần đây, sản lượng bột cá đang giảm dần và giá thành ngày một tăng.
By 2009, the server consolidation effort had resulted in consolidating 1,250 servers down to only 250 while
consuming 60% less space, 70% less power, and 70% less cooling. These results came from the first two server
virtualization tactics. Tactic 1 (virtualizing new, dedicated application environments) helped EMC to avoid buying
640 physical servers through December 2008. CPU utilization was not optimized, with the P2V consolidation ratio
remaining at only 5:1, because servers were still dedicated to specific applications.
A transmission or gearbox provides speed and torque conversions
from a rotating power source to another device using gear ratios,
including for a motor vehicle partly because of the limitations of
internal combustion engines.Usually found near motors of some sort, gearboxes are used to
reduce the load on the motor by using the motor's own momentum
to keep it turning.
Disproportionation of toluene with xylene high yields was studied over modified Y zeolite synthesized from kaolin of Vietnam. The effects of reaction temperature, weight hourly space velocity (WHSV) and of HZSM-5/HY ratios on toluene disproportionation have been investigated. The optimal condition of obtain the xylene high selectivity and the conversion of toluene is 17.15% HZSM-5/HY, WHSV = 3.99 h-1 and 438.6o C.
Feed Conversion Efficiency (FCE) can be defined as the volume of milk produced by the
cow per kilogram of feed consumed by the cow and acts as an accurate indicator of the
effectiveness of the feed ration. A fundamental aim of the dairy farmer is to maximise this
ratio. Optimising rumen function is the first step towards achieving a favourable FCE. The
passage and rumination of the feed ration can be determined by faecal consistency. Faecal
consistency can be rated on a scale of 1-5 with a score of 1 indicating watery faeces...
Chapter 3, Systems of measurement and weight, reviews weights and measures. It introduces the metric system as well as apothecary and household systems. Time and temperature conversions are included. Special attention is given to conversion factors, and the procedures for ratio proportion, fraction proportion, and dimensional analysis methods are introduced as building blocks for later chapters.
