Grass pea (Lathyrus sativus L.) has a high potential for forage production inboth rangelands and cultivated rainfed areas of Iran. It is well adapted to semi-arid areas ofwest and north of country where annual rainfall is 250–350 mm. To study the seed and DryMatter (DM) yield and agronomic traits, six genotypes of Lathyrus sativus L. and twogenotypes of Lathyrus inconspicuous L. were provided b...

The objective of this work was to evaluate the performance, carcass traits and economic indicators Santa Inês lambs their crossings finished in feedlot. Thirty whole (10 Inês, 10 ½ Dorper + ¾ ¼ Inês) were used, with 115 days age initial live weight 20.07 kg. kept for 60 receiving sorghum silage concentrate, after which they slaughtered. showed higher dry matter intake water intake, greater dail...

Thirty-two crossbred wether lambs (initial live-weight 31 kg) were fed on a diet (metabolizable energy (ME) 12.8 MJ/kg) ad lib. (ADLIB) or restricted to maintain body-weight (MAINT) for a 21 d period. On days 0, 7, 14 and 21, four lambs per treatment were slaughtered, visceral organs weighed and tissues sampled. During the 21 d period, ME intake in ADLIB lambs increased quadratically with an av...

One hundred and seven Limousin or Charolais crossbred steers averaging 234.58 kilograms each were randomly assigned to one of three diets. The first diet contained a commercial supplement to increase the ration's protein level. The second group received a diet fortified with flaked roasted soybeans. The third group was fed a diet containing whole roasted soybeans as a supplemental protein sourc...

Milk urea nitrogen (MUN) of dairy cows was determined in relation to breed. A total of forty (40) Pabna and red Chittagong dairy cattle each of twenty (20) were selected to know the milk composition, nutritional status and milk urea nitrogen. Live weight of Pabna Cattle (187±14 kg) was higher than that of red Chittagong cattle (174±4 kg). In Pabna cattle milk yield (4.94 kg), minerals (0.15%) a...

this research was conducted to investigate the effects of fennel by product (fbp) on productive performance of growing lamb and in vitro gas production parameters, using 20 afshari×chal male lambs (bw = 49 ± 0.24 kg) were used in a randomized complete block design. experimental treatments consisted of diets including of 0, 3, 6 and 9% of fbp (dry matter basis). dietary treatments had no effect ...

Effects of a blend live yeast and organic minerals as an alternative to monensin inorganic trace for beef cattle finished on pasture with high concentrate supplementation, growth performance, intake, digestibility, liver mineral carcass characteristics were evaluated. Forty-eight Nellore bulls blocked by initial body weight randomly assigned one the two experimental diets. The animals raised in...

Twenty-eight Comisana dry ewes were utilised to evaluate the effect of shearing (14 shorn and 14 unshorn ewes) and supplemental level (100 and 300g of concentrate) on intake of barley stubble. Shorn ewes showed a small increase in dry matter intake (at the end of August: 1.32 vs. 1.10kg/day; p<0.01). Intake of barley stubble decreased as supplement level increased (mean: 1.18 vs. 1.29; p<0.01)....

A feeding trial with twenty-seven male weaned Zandi lambs (initial body weight 27.1±0.38 kg) was conducted to evaluate the effect of different levels of Saccharomyces cerevisiae SC47 in diet containing high concentrate (85%) on the growth performance, blood parameters and immune system status. Lambs were allocated to one of three treatment diets in a completely randomized design with 3 replicat...

It is essential to quantify the potential of tropical grasslands to allow significant feed efficiency for grazing livestock in controlled conditions such as at pasture. We conducted a quantitative analysis of published studies reporting the experimental results of average daily gains (ADG) and diet characteristics obtained specifically under grazing conditions (17 publications and 41 experiment...
