A completely randomised design study involving 132 continental crossbred beef steers was undertaken to evaluate the effects of method of grain treatment and feed level, and grass silage feed value on animal performance, carcass characteristics and meat quality of beef cattle. Winter wheat was harvested and the grain was stored either ensiled crimped and treated with 4.5 l/t of a proprietary aci...

Sheep in many areas of Australia and New Zealand experience periods of variable feed supply. Merino sheep can be bred to be more resilient to this varying feed supply. Resilient sheep lose less live weight when grazing poor quality pasture. However, we do not know if breeding for live weight change genetically affects reproduction. To estimate genetic correlations between live weight change and...

The genus Jatropha is distributed through out the tropics and sub-tropics growning in marginal lands and is a potential biodiesel crop world wide. The plants can prevent soil erosion, grown as a live fence and used as an alternate commercial crop. The seed oil can be used as a feed stock for biodiesel. Alternatively Jatropha oil is used in soap, glue or dye industry. The seed cake is rich in ni...

this research was conducted to evaluate the effect of different zinc (zn) sources on performance, bloodmineral and cell counts of zandi lambs. 18 male lambs at weaning were supplemented with two differentsources of zinc, 25 ppm znso4 and 25 ppm zinc-peptide added to the basal diet as control. live bodyweight, weight gain and feed efficiency improved with zn-peptide supplementation (p

abstract 900 rainbow trout (mean weight 25 gr) were obtained from a local fish farm in urmia city and after acclimatization for 10 days, the fish were randomly divided into four groups (with three replication) and fed for 8 weeks with 0 (control), 2/5, 5 and 10 g chitosan/kg feed, respectively. finally treatments were fed the control diet (without any chitosan) for another 3 weeks. body weight,...

Increasing the lactating sow feed intake is generally considered beneficial, but high inter-individual variability of the measurements makes difficult designing the trials on this subject. A meta-analysis of 10 trials (1111 sows, 8 genetics lines, parity 1–8, lactation duration 19–31d) was undertaken, comparing “control” diets (n = 12) to diets supplemented with the same strain of live yeast Sa...

AIM The aim of this study was the assessment of various levels of date palm kernel (DPK) on the growth performance of broilers. MATERIALS AND METHODS A 250-day-old broiler chicks were randomly selected and categorized into five groups (50 chicks/group) contained A (control), B, C, D and E fed with 0%, 1%, 2%, 3% and 4% levels of DPK in balanced ration, respectively, for 6 weeks. Feed and wate...

Dried cashew nut testa (DCNT) was characterized with respect to proximate, mineral, and energy profile. The crude protein, crude fibre, and fat and ash contents were, in g kg(-1)DM, 190.0, 103.0, 20.1, and 20.2, respectively, with metabolizable energy of 7.12 MJ kg(-1) DM. In a feeding trial, isoproteic diets containing DCNT (O, 50, 100, and 150 g kg(-1)) were fed ad libitum to 4 groups of Spra...
