The paper studies the effect of additional administration ultrafine particles on cattle rumen microbiome composition. in vitro method was used using ANKOM Daisy II incubator according to a specialized method. Microflora analysis performed MiSeq (Illumina, USA) by new generation sequencing with reagent kit. After detailed structure and composition microbial community contents sampled for differe...

Mevcut çal??mada, ruminant hayvan beslemede kullan?lan, tanen içeren yem hammaddelerinin rasyonda kullan?lmas?ndan do?abilecek etkilerinin göz önüne al?nmas? ve buna göre rasyonlar?n?n düzenlenmesi amaçlanm??t?r. Bu amaçla, farkl? hammaddelerinde bulunan de?erleri belirtilerek, beslenme çal??malar?nda hayvanlar üzerindeki pozitif negatif etkileri ortaya konulmaya çal???lm??t?r. Hayvan besleme a...

To verify research from this laboratory indicating that sheep omasal epithelium contains mRNA encoding for a peptide transporter(s) and to determine di- to octapeptide transport capability, we injected poly(A)+ RNA isolated from sheep omasal epithelium into Xenopus laevis oocytes. Poly(A)+ RNA was functionally expressed in Xenopus oocytes 4 to 7 d after injection. Peptide (5 di-, 10 tri-, 6 tet...

Since 2001 the European Commission banned the use of meat and bone meal and its byproducts in diets for livestock animals (EC directive 999/2001) in order to assure consumer safety on animal products. Consequently, soybean meal became the most utilised protein source in the intensive livestock systems. Moreover, the proteins of this source are low degradable in the rumen and well proportioned t...

The overly thin sheep or goat is a common presentation for veterinary intervention, either as the client’s chief complaint or a finding during other herd work. Poor body condition is a non-specific sign caused by a wide variety of underlying pathophysiologic processes. Definitive diagnosis and successful treatment or herd interventions will be facilitated by using a step-wise, problem-based app...

Scientific data for carcass traits of terminal-sire sheep breeds can be used to improve the value of market lambs, but information is lacking for modern terminal-sire breeds in the United States. Thus, the effects of terminal-sire breed on 14 fabricated carcass measurements were determined in F1 wether lambs. Columbia, USMARC-Composite (Composite), Suffolk, and Texel rams were mated with mature...

Iron (Fe) and copper (Cu) metabolism are closely intertwined, and a deficiency of Cu may lead to a secondary Fe deficiency. The impact of a severe Cu deficiency on proteins involved in Fe metabolism in the bovine has not been studied. Therefore, a 493 day study was conducted to determine the effect of a severe long-term Cu deficiency on Fe metabolism in beef cattle. Twenty-one Angus calves were...
