Effects of supplementary feeding on growth and carcass characteristics of fat-tailed lambs grazing cereal stubble
Despite a shortage of animal feed in Iran, cereal stubble is often underutilized due to agro-economic reasons. On the other hand, lambs fed with a conventional fattening ration deposit a considerable amount of fat; therefore, this experiment was conducted aimed at better utilization of cereal stubble and reducing the fat content of lamb carcasses. Fat-tailed Mehraban and Ghezel ram lambs were p...
متن کاملFeeding weaned piglets and growing -
In 2000, EU regulations for organic animal production set new guidelines for organic pig feeding requiring that this be based on mainly home-grown organic feedstuffs. Doubts were however raised whether these feeding regimes can maintain good growth performance and carcass quality of pigs. Three experiments were carried out to study different organic feeding regimes in weaned piglets and fatteni...
متن کاملHow Much Supplement is Needed for Early Weaned Calves Grazing Rye- Ryegrass Pastures?
The objective of this study was to evaluate the effect of three levels of supplement on forage intake and animal performance of early weaned calves grazing rye-ryegrass pastures from January to May. Treatments were three levels of concentrate (1, 1.5, and 2% of body weight [BW]), and animals were 90-d-old Angus-crossbred early weaned calves. Calf ADG increased from 1.6 to 1.9 lb/d as supplement...
متن کاملImpact of rotational grazing on management of gastrointestinal nematodes in weaned lambs.
Gastrointestinal nematode (GIN) control for 'natural' or organic lamb production is needed, especially where Haemonchus contortus is prevalent. The objective was to determine the impact of rotational grazing on GIN infection of weaned lambs. In year 1, naturally infected Katahdin lambs (120 days of age) were randomly assigned to graze (1) continuous bermudagrass (CB; n=14), (2) rotational bermu...
متن کاملPrevalence of Giardia spp. infection in pre-weaned and weaned calves in relation to management factors.
Two hundred and forty calf faecal samples from 16 Malaysian farms were screened by PCR for Giardia spp. The overall prevalence was 12.5% and the overall farm prevalence was 68.8% (11/16 farms). The prevalence in pre-weaned and weaned calves was 16.7% and 8.3%, respectively. Sequence analysis of 25 isolates identified all as G. duodenalis assemblage E. Management factors associated with an incre...
