The influence of separation from dam on suckling behavior of lambs was tested from day 5 after lambing until the lambs were 8 days old. The twelve ewes with their lambs were randomly assigned in equal numbers to two treatments; separating from dam (S) and non-separating without suckling (NS). Separation from dam resulted in lower duration and higher frequency of suckling. The lambs in S treatme...

in order to study the effect of dietary physical form on the fattening performance of holstein male calves, an experiment was conducted in animal science research institute of iran in 2011. the experimental diets were formulated and prepared with two physical forms including total mixed ration (tmr) and densified complete feed block (dcfb). in a completely randomized block design, with two trea...

this experiment was conducted to investigate the effects of using three commercial enzymes on performance and carcass quality of broiler chickens fed with wheat-barley-soy based diets. in a completely randomized design 405 of broiler (ross308) in nine treatments, three replicates (with 15 bird in each replicate) were used. the experimental diets included 1) diet based on corn–soybean meal (with...

this study was conducted to evaluate production response of early lactating cows to rumen protected fats. twelve (nine multiparous and three primiparous) holstein cows (26±4 d in milk) were empolyed in a replicated 3×3 latin square design of 21-d periods. each period consisted of 14 days of adaptation and 7 days of sampling. cows received diets containing either one of two types of protected fa...

This study aimed to evaluate the performance, some carcass characteristics from feedlot lambs receiving sunflower crushed (SC) in the diet on partial replacement of soybean meal. The experimental design was randomized block with four levels of SC in the diet (0, 10, 20 and 30% of dry matter (DM)). There was a linear reduction of 0.02; 0.003; 0.003 and 0.17% for each percentage unit of added SC ...

three experiments were conducted to evaluate the nutritional value of bitter vetch. experiment 1 was conducted to determine the metabolisable energy content of bitter vetch. sixteen adult leghorn roosters were used. forty grams of bitter vetch were precision-fed individually to 12 roosters. in addition, 4 birds were not fed and served as a control treatment in the measurement of metabolic fecal...

. an experiment was conducted by incorporating 35 newborn balouchi lambs to study the effects of different type and levels of forage in starter diets on rumen development characteristics and performance. the 5 experimental treatments were included; starter diet without forage (control) and starter diet containing two levels (7.5 and 15%) of alfalfa hay and wheat straw. inclusion of forages incr...
