Detoxified castor meal in substitution of soybean meal in sheep diet: growth performance, carcass characteristics and meat yield

Abstract

The aim of this study was to evaluate the intake, digestibility, performance, and carcass characteristics of lambs fed different levels of replacement (0, 15, 30, and 45 % based on dry matter, DM) of soybean meal (SM) by detoxified castor meal (DCM). Twenty-four and 32 intact hair lambs of nondescript breed (21.7 ± 2.6 kg of initial average body weight and approximately 10 months old) were used, respectively, in the intake and digestibility and performance experiments. The diets were composed of buffel grass hay, ground corn grain, and different levels of SM, DCM, and urea, in a roughage-to-concentrate ratio of 40:60. There was no effect of treatments on DM intake. However, crude protein (CP) and neutral detergent fiber (NDF) intakes were higher at 30 and 45 % than at 0 and 15 % of DCM, which in turn showed higher intake of non-fiber carbohydrates (NFC) (P < 0.05). The organic matter, CP, and NDF digestibilities were not affected, but the digestibility of NFC was lower at 30 and 45 % than at 0 % of DCM (P < 0.05). The average daily gain, feed conversion, slaughter and carcass weights, chilling losses, ribeye area, and absolute values and yields of neck, ribs, loin, and leg were not affected. However, the carcass yield was lower at 45 % of DCM and the absolute value of shoulder was lower at 30 and 45 % of DCM (P < 0.05). The replacement of SM by DCM up to 45 % in the feed of lambs did not negatively affect the intake, digestibility, performance, and main carcass features.

Replacement of soybean meal with treated castor bean meal in supplements for grazing lambs

“…Menezes et al (2016) observed no difference in feed efficiency when lambs were fed increasing CBM dietary concentrations. However, Pompeu et al (2012) observed a decrease in feed efficiency as CBM was increased in the lambs' diets.…”

“…Castor bean meal may be an economically viable alternative in ruminant feeding systems. The current literature related to CBM for ruminants has mainly targeted nutritional value and production performance for feedlot cattle and sheep (DINIZ et al, 2010;MENEZES et al, 2016;POMPEU et al, 2012), and there is little information about the effects of its use in supplements for grazing ruminants, especially growing sheep. Thus, it is necessary to establish of the optimum inclusion of CBM in supplements for grazing lambs.…”

Effectiveness of Proprioceptive Exercise on Balance and Sensory Function in Nursing Home Geriatric Individuals with Diabetes: Randomized Controlled Trial

“…[4][5][6][7] Symptoms such as pain, numbness, and loss of sensation, especially the increasement of vibration and thermal perception threshold on distal lower extremity may be indicative of neuropathy and it affects approximately 50% of the individuals with diabetes. [8][9][10][11] Proprioceptive exercises are included in rehabilitation in order to reduce somatosensory loss and increase balance abilities. [12][13][14] However, disruption in balance control of geriatric individuals are not only associated with diabetic neuropathy.…”

Metabolic stress and reproductive features in post-partum goats supplemented for a long period with detoxified castor meal as the source of dietary nitrogen

“…This discrepancy in the in vivo performance of the kids was undoubtedly due to the increase in milk production. (Menezes et al, 2016). However, the use of detoxified castor bean meal in place of soybean meal can contribute to the reduced production and milk composition in cows (Cobianchi et al, 2012) and reduced the digestibility of dry matter, organic matter, crude protein, and total carbohydrates in finishing animals (Silva et al, 2011).…”
