The aim of this study was to investigate the effects of saccharomyces cerevisiae yeast and butyrate monoglycerides on the performance, blood parameters and nutrients digestibility in suckling Holstein calves. For this experiment, 32 newly-born Holstein calves (average age 1-8 days; average weight 38±1 kg) were used in a completely randomized design with 2×2 factorial arrangement, 4 treatmen...
twenty male raini goats with an average live weight of 30 ± 2.5 kg and 18 month of age. ,were used in a completely randomized design with 4 experimental diets and 5 replications to study effect of different levels by-pass(udp) protein(2.75, 4.86, 5.91 and 6.97 percent in dry matter) on growth and carcass characteristics. metabolismable energy (me) level of the all diets were similar (10.04 mj m...
اثر متاپروترنول، یک بتاآدرنرژیک اگونیست، بر رشد، ضریب تبدیل غذایی و ترکیب لاشه بره های ماده ورامینی
Effects of the β-adrenergic agonist metaproterenol were studied daily gain, carcass composition and feed consumption of Varamini female lambs were studied. Thirty lambs were randomly assigned to a randomized complete block design with three groups (treatments) and two blocks (live weight). The ration was similar for all groups (ME: 2.6 MCal/kg, CP: 14.9%) and lambs were fed ad libitum. Metapr...
Upazila Livestock Office, Chirirbandar, Dinajpur, Bangladesh A beef breed development project was carried out in the Department of Livestock Services (DLS) in 2009 in selected areas of Bangladesh. Under this project, semen of Brahman bulls were imported from the USA and used to inseminate indigenous cows to produce graded calves. The present study was undertaken to select graded Brahman bulls o...
Guilani sheep, with a population 900 thousand heads, produce 16% of meat and 5% of milk in this province. However, no estimation for genetic parameters of various traits in this breed has been provided up to now. The aim of this study was to estimate genetic parameters for body weight at birth (BW), three months of age (3MW), six months of age (6MW), average daily gain from birth to three mon...

The effects of methanolic extract and leaf powder of Artemisia annua were studied on performance, cellular and humoral immunity in 240 Cobb broiler chicks in a completely randomized design. Control group did not receive any treatment. The chicks in the second and third groups were fed with feed which contained 2000 and 4000 ppm plant extract in diet and in the groups 4, 5 and 6 chicks received ...
This contribution discribes a new method for monitoring productivity in the slaughter pig production unit. The method is implemented with a graphical user interface. By calculating average daily gain each time a group of slaughter pigs is delivered to the slaughterhouse, a time series is made. Among other features, the application allows the user to monitor the time series graphicaly. Monitorin...
GRANT, C. C. BIGGS, H.C. MEISSNER, H.H. & SASSON, P.A. 1996. The usefulness of faecal phosphorus and nitrogen in interpreting differences in live-mass gain and the response to P supplementation in grazing cattle in arid regions. Onderstepoort Journal of Veterinary Research, 2:121-126 The average daily gains of heifers and oxen on commercial and experimental farms in Namibia were used to indicat...
