This study aimed to evaluate the effects of ground or steam-flaked corn and zinc-enriched yeast addition grower pellet feed on fattening performance, rumen papillae development, some blood parameters in lambs. For this purpose, thirty-six Kivircik male lambs were selected divided equally into six groups: basal diet containing without different form (control), 80% + 20% (PGC), (PFC), PGC Zn-enri...

Twenty-four 35-day-old lambs were distributed to a completely randomized design with 3 treatments to study the effects of number of feeding buckets per pen on performance, haematology and behaviour indicators. Treatments consisted of 8 (T1), 4 (T2) or 2 (T3) feeding buckets/pen (8 lambs/pen). During the experiment, concentrate was fed at 08:30 in individual feeders. Daily dry matter intake (DMI...

RATIONALE Inhaled nitric oxide (iNO) can reverse neonatal pulmonary hypertension and bronchoconstriction and reduce proliferation of cultured arterial and airway smooth muscle cells. OBJECTIVES To see if continuous iNO from birth might reduce pulmonary vascular and respiratory tract resistance (PVR, RE) and attenuate growth of arterial and airway smooth muscle in preterm lambs with chronic lu...

a crossbreeding experiment involving four iranian fat-tailed sheep breeds, namely kurdi (k), chaal (c), afshari (a) and sanjabi (s) was carried out to determine the ram breed effects on productivity of kurdi fat-tailed ewes (k) under extensive production system. a total of 475 kurdi ewes were mated to 24 rams from four breeds producing 454 lambs including pure kurdi, kk, (116 lambs), afshari × ...

Urea-nitrogen recycling to the gastrointestinal tract (GIT), N metabolism, and urea transporter-B (UT-B) mRNA abundance in ruminal epithelium were evaluated in partially defaunated (PDFAUN) and faunated (FAUN) growing lambs fed 2 levels (10%, low, or 15%, high) of dietary CP (DM basis). Four Suffolk ram lambs (43.9 +/- 1.4 kg initial BW) were used in a 4 x 4 Latin square design with 27-d period...

Dose-dependent pharmacokinetics and metabolism of valproic acid (VPA) were studied in newborn and adult sheep to assess age-related differences in plasma protein binding and metabolic elimination. Newborn lambs received either a 10- (n = 8), 50- (n = 5), 100- (n = 4), or 250-mg/kg (n = 4) VPA i.v. bolus. Individual adult sheep (n = 5) received all four doses in a random order with an appropriat...

Abstract This study was conducted in the fields of breeding and improving sheep goats at Al-Dabouni research station district, Wasit Governorate affiliated to General Authority for Agricultural Research / Ministry Agriculture, from 8/2/2022 7/6/2022. A total 24 male Awassi lambs, aged between 4-5 months, were used (4 Al-Mahatta lambs 20 purchased a breeder Jassan district), average starting wei...

two experiments were conducted to evaluate the different levels of selenium supplements on performance, blood metabolites and nutrient digestibility in mehraban male lambs. the first experiment consisted of 18 lambs, 4-5 months of age and 35.9±2.7 kg average in weight randomly allotted to 3 treatments. treatments were: 1) control diet (a diet without selenium, containing 0.06 ppm of selenium), ...

Nutrient absorption is important in all stages of life. As the diet of an animal changes from birth on, morphological and biochemical adaptation can be anticipated in order to accommodate changing demands. The main focus of the present study was to examine the relationship between age and diet on the potential for peptide transport via PepT1 in the gastrointestinal tract of lambs and to relate ...

The effects of Saccharomyces cerevisiae supplementation (6.6×10(8) cfu) and anhydrous ammonia treatment (3%) of wheat straw (WS) were investigated on in-situ dry matter (DM) degradability, and on rumen fermentation and growth performance of lambs. Rumen-fistulated Menemen sheep fed a diet with and without live yeast were used to assess the DM degradability characteristics of WS and ammonia-trea...
