background: coccidiosis is recognized as the parasitic disease that has the greatest economic impact on poultry production. modern poultry production is largely dependent upon anticoccidials. objectives: the aim of the present study was to determine and compare the efficacy of two chemical anticoccidials (clopidol and diclazuril) on oocyst shedding and their probable effects on growth performan...

Context It has been indicated that there might be an antagonism between selection for gastrointestinal nematode resistance and high productivity feed conversion efficiency in ruminants. Aims This study aimed to determine whether genetic nematodes would alter the intake of sheep with or without infection Haemonchus contortus. Methods Sixty-seven Corriedale lambs (357 ± 14 days old) derived from ...

the effect of a commercial probiotic (protexin) on growth performance and survival rate in sobaity sparidentex hasta was investigated. 240 fish with average weight of 2.99±0.87g were treated for 10 weeks. this study was carried out in a completely random design with 12 experimental groups, in 4 treatments each with 3 replicates. experimental groups were consisted of four levels of 0.0, 0.5, 1.0...

Laboratory facilities use many varieties of contact bedding, including wood chips, paper products, and corncob, each with its own advantages and disadvantages. Corncob bedding, for example, is often used because of its high absorbency, ability to minimize detectable ammonia, and low cost. However, observations that mice eat the corncob lead to concerns that its use can interfere with dietary st...

six hundred day old unsexed broiler chicks were used in a 42-d trial at chittagong veterinary and animal science university poultry farm to compare the effects of different levels of fish oil supplementation on performance of broilers in terms of feed intake, weight gain and feed conversion and carcass characteristics. the chicks were randomly distributed following a completely randomized desig...

An effective method was elaborated for extracting the active substances from commercially available Garden thyme and carob seeds. The antibacterial activity of dilutions of thyme and carob extracts and their combinations were studied by taking the minimum inhibitory concentrations (MIC) with agar well diffusion technique. The most effective concentrations of the two herb extracts were used for ...

six hundred day old unsexed broiler chicks were used in a 35-day trial to compare the effects of soybean oil, palm oil and fish oil supplementation on the performance of broilers in terms of feed intake, weight gain and feed conversion. the chicks were randomly distributed following a completely randomized design in four groups having three replications per treatment. each treatment had 150 bir...

The influence of rumen microbial structure and functions on host physiology remains poorly understood. This study aimed to investigate the interaction between the ruminal microflora and the host by correlating bacterial diversity with fermentation measurements and feed efficiency traits, including dry matter intake, feed conversion ratio, average daily gain, and residual feed intake, using cult...
