The study examined the effect of raw and roasted cereals (corn, oat and barley) and soybean in diet on growth performance and blood parameters of lambs fattening. Totally 60 lambs after ablactation at average of 50 days, were tested and equally divided into three groups: an experimental I (E I), experimental II (E II) and a control (C) group. The fattening period lasted 56 days. Lambs of the C ...

CAMERON, C. M., 1980. Effective immunization of lambs against enterotoxaemia. Onderstepoort Journal of Veterinary Research, 47, 287-289 (1980). In contrast to adult sheep, 2to 3-month-old lambs do not respond well to a single injection of Clostridium perfringens Type D oil adjuvant epsilon toxoid. This unresponsiveness can be overcome, however, by administering 2 injections of oil adjuvant vacc...

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 × ...

Vegetable oils containing stearidonic acid (SDA, 18 : 4n-3) are considered better precursors of long-chain n-3 PUFA (LC n-3 PUFA) than those with only α-linolenic acid (ALA, 18 : 3n-3). The present study re-examined this premise using treatments where added ALA from linseed oil was matched with ALA plus SDA from echium oil. Lambs (n 6) were abomasally infused with saline (control (C), 25 ml), e...

Leptin has been implicated in the regulation of feed intake, growth, and reproduction. The objective of this study was to determine if centrally administered leptin would affect feed intake and the secretion of growth hormone (GH) and luteinizing hormone (LH) in ewe lambs. Eighteen ewe lambs were ovariectomized and fitted with intracerebroventricular (i.c.v.) cannulae. Lambs were randomly assig...

Data were collected on 130 intact male lambs fed diets based on roughages supplemented with fish meal, soybean meal, or corn gluten-blood meal and slaughtered at 43 kg live weight. A nonsupplemented group served as a control. The lambs represented Romanov (R), Finnsheep (F), a new breed developed in Canada (DLS), Coopworth (C), and Suffolk (S), three first crosses of DLS with R, F, and Booroola...

The effect of forage and breed of lambs on the fatty acid profile of intramuscular fat in m. longissimus lumborum (LL) and depot fat (SCF) above this muscle was investigated. The study was carried out in two replications on 36 Koluda sheep (KS) and Ile de France×KS (IF×KS) ram-lambs fattened intensively to 32–37 kg of body weight. Lambs were fed ad libitum the same concentrate mixture and diffe...

The aim of this study was to determine how one group of lambs utilized 2 consecutive rest periods in novel environments with access to food and water that occurred during 22 hr of motor transport. The 18.5 +/- 0.6 kg lambs (n = 15) were transported for 8 hr and then unloaded for a 6-hr rest period. After 6 hr, the lambs were reloaded for another 8 hr of transport followed by a 24-hr rest period...

I . The mean liver retinol reserve (retinal+ retinyl esters, expressed as retinol) of six newborn lambs was 21 ? 8 pg. The mean value for ten suckled lambs, aged 5-7 days, was 2655 +47z pg retinol per liver. 2. Three unsuckled lambs were fed ad lib. from birth for 28 days on a high-protein diet, based on lard and skim milk, without supplementary vitamin A. The diet provided sufficient vitamin A...

Crossbred lambs (47.3 kg BW) were used to study the effects of restraint and isolation stress on endocrine status and blood metabolites, antemortem glycogenolysis, and incidence of the dark-cutting condition (DCC) in the longissimus muscle (LM) and to determine the role of muscle contraction in the formation of the DCC in sheep. Lambs were assigned randomly to three treatments: unstressed contr...
