Feeding behavior in lambs fed diets containing crambe cake

Abstract

It was evaluated the feeding behavior of lambs fed diets containing 30% sorghum silage and 70% crambe cake (30:70 diet), and 70% sorghum silage and 30% crambe cake (70:30 diet) under voluntary and controlled consumption. The experimental design used was a 4 × 4 Latin square, with four animals, four periods, and four treatments; feeding behavior was determined by observation. The results indicated that animals fed the 30:70 diet showed higher DM and NDF (g day -1 ) than those fed the 70:30 diet. Animals fed the 70:30 diet showed longer feeding times (h kg -1 DM), mastication (min kg -1 DM and min kg -1 NDF), rumination (min day -1 and min kg -1 DM), and the largest number of mericics chewing per bolus; however, a higher feed efficiency (g DM h -1 ) was observed in the 30:70 diet group. Furthermore, animals feeding voluntarily had higher DM intake and chewed for longer. Therefore, the combined results indicated that crambe cake could be used in the diet of sheep without affecting feeding behavior.

Performance, ingestive behavior and carcass traits of lambs fed rations containing soybean cake

“…Although the NDFI showed a quadratic response to the soybean cake levels, this variation in fiber intake not affected the rumination time. This result is not in accordance with that obtained by Syperreck et al (2016), who reported an increase in rumination time (421 to 497 min day -1 ) with an increase of the roughage:concentrate ratio, from 300 to 700 g kg DM -1 in rations composed of sorghum silage and crambe cake. In this case, the increase of rumination activity was related to the high content of large fibrous particles in the ration with higher roughage content.…”

This may be associated with the higher NDF content of the rations evaluated in those studies (661.5 and 543.0 g kg DM -1 , respectively) compared to the rations used in the present study (ranging from 375.4 to 522.7 g kg DM -1 ; Table 2).…”

Biotechnological approach for improvement of Crambe species as valuable oilseed plants for industrial purposes

“…7,24 The waste after seed oil extraction can potentially be used for animal feed as a protein supplement due to the high content of crude protein (up to 45%). 31,36–45…”

Crambe (Crambe abyssinica Hochst): A Non-Food Oilseed Crop with Great Potential: A Review

“…Increased use of crambe meal in lamb (Ovis aries L.) diet has resulted in poor performance, increased hepatic injuries to animals, poor meat quality, and meat containing higher erucic acid content than the limit allowed as safe for human consumption [97]. Oppositely, Itavo et al [25] and Syperreck et al [26] reported no negative effects on lamb carcass quality and animal performance when crambe meal was less than 20% of the ration.…”
