“…In this study, the negative effect of WCS was not observed in Awassi lambs because low levels of WCS were used. The ADG of 8.5% WCS group (268 g/d) had similar values to former studies of Can et al (2004) and Can et al (2005) with the same breed under similar conditions.…”

“…Additionally, Luginbuhl et al (2000) reported that with increasing WCS level in diets of male goats, serum urea concentration increased. Glucose, urea and total protein levels of lambs were similar in a former study by Can et al (2005).…”

“…On the other hand, in some studies a decline in DMI was reported (Luginbuhl et al, 2000). The feed efficiency value of the current study was found to be higher than former studies of Can et al (2004) and Can et al (2005). This can be explained by different initial and final bodyweights of lambs and diet composition in their studies.…”

This study was carried out to determine the effect of whole cottonseed (WCS) supplementation on finishing performance and blood parameters of Awassi lambs under heat stress. The compositions of diets for the various treatments were i) control: concentrate without WCS plus 15% wheat straw; ii) 8.5% WCS, 76.5% concentrate and 15% wheat straw; and iii) 17% WCS, 68% concentrate plus 15% wheat straw. Twenty seven male Awassi lambs (4-5 months old) were allotted to three dietary treatments in equal numbers for each diet in a completely randomized design. Following 15 days of diet adaptation, lambs were fed the experimental diets ad libitum for 56 days. According to the finishing trial, average daily gain (ADG), feed intake (FI), dry matter intake (DMI), feed efficiency and water consumption were not affected by the inclusion of WCS. Only numerical increment of daily gain, FI and DMI was observed in the 8.5% WCS group. Supplementation of WCS did not affect blood glucose, urea, total protein, albumin and potassium levels, but blood cholesterol level was increased. Changes in scrotal circumference were observed with supplementation of 17% WCS. As a result, WCS can replace concentrate up to 8.5% of diet without negative effects on finishing performance of Awassi lambs under heat stress conditions.

“…This proposed mechanism is consistent with the decreased BUN in GLU-fed lambs in both thermal regimes (Table 3). In contrast, other nutritional strategies such as adding bypass protein (Bunting et al, 1992;Can et al, 2005) or supplemental fat (Caroprese et al, 2012) failed to affect core body temperature. It should be noted that the GLU product contained some niacin, and (although results vary) niacin has been shown to reduce body temperature in lactating heat-stressed cows (Zimbelman et al, 2010;Rungruang et al, 2014).…”

“…Authors attributed these differences to improved nutrient (NDF and CP) digestibilities when lambs or calves consumed diets containing high levels of RUP as compared to low levels of RUP. Can et al (2005) reported that rate of growth and efficiency were improved in lambs fed a diet containing bypass protein (fishmeal) when compared to rumen degradable protein in lambs fed finishing diets. These results are in agreement with others (Orskov et al, 1970;Beermann et al, 1986) who demonstrated that bypass protein that came from fishmeal enhanced the rate of growth of lambs more than diets containing plant protein sources.…”

Two experiments were conducted to evaluate the effect of replacing soybean meal with xylose-treated soybean meal (soypass meal; SPM) on performance of nursing Awassi ewes and fattening lambs. In Experiment 1, lasting for eight weeks, 39 Awassi ewes and their lambs were randomly assigned to three diets. Diets were formulated by replacing soybean meal from the basal diet (CON-SBM; n=13) with 50% (50% SPM; n=13) and 100% (100% SPM; n=13) SPM. Initial and final weights of the ewes were not different (P>0.55) among diets. Total gain and average daily gain (ADG) of lambs were similar (P=0.44) among diets. Ewes fed the CON-SBM diet tended (P<0.09) to have lower milk yields than those fed the 50% SPM and 100% SPM diets. No differences (P>0.38) in milk component percentages among diets were observed. In Experiment 2, lasting for 63 days, twenty weaned lambs were used to determine the effects of replacing soybean meal with SPM on growth performance. Diets were either soybean meal (SBM; n=10) or SPM (SPM; n=10). Nutrient intake and digestibility were not different between diets. However, rumen undegradable protein intake was greater (P<0.05) for the SPM diet than for the SBM diet. Final body weight, ADG and the feed conversion ratio were similar (P>0.05) between the diets. Results suggest that replacement of soybean meal with soypass meal is not likely to produce any production benefits in nursing Awassi ewes and fattening lambs except for the slight improvement of milk yield
