Abstract

The present study was conducted to evaluate the effect of feeding conch shell (Turbinella pyrum) powder (either fresh or calcined) as a marine organic source of calcium (Ca) supplemented in the diet of crossbred calves on voluntary intake, growth performance, and blood biochemistry in growing crossbred Jersey calves. A growth trial of 90 days was conducted on 15 Jersey crossbred female calves (Av. weight, 70.68 ± 2.90 kg; Av. age, 197.73 ± 12.40 days), equally divided into three groups of 5 animals each, i.e., control (T0), treatment 1 (T1), and treatment 2 (T2). All animals were fed total mixed ration (TMR) prepared with a concentrate mixture, chaffed paddy straw, and green fodder at the ratio of 40:30:30 on DM basis. Calves under the control group were fed with TMR containing a standard mineral mixture having dicalcium phosphate (DCP) as a Ca source. Calves under T1 group were supplemented with TMR containing fresh conch shell powder (FCSP), and T2 calves were fed with TMR containing conch shell calcined powder (CSCP) as Ca source. We observed 11.66% increase (p < 0.01) in Ca concentration in CSCP compared to FCSP. The concentration of minerals like Mg, Co, Mn, and Fe was enhanced in CSCP compared to the FCSP. However, the calcination process of fresh conch shell powder (FCSP) reduced the concentration of Cu, and Zn. The Ca/P ratio was estimated as 2.11, 2.06, and 2.10 in T0, T1, and T2 diets, which could be considered ideal for calf ration. Calves under T1, and T2 groups consumed significantly (p < 0.001) greater amounts (g/kg W0.75) of DM and CP compared to T0. However, increased voluntary intake did not translate into increased body weight gain (kg), and feed conversion ratio (kg DMI/kg gain) in T1 and T2 groups in comparison to T0. We observed similar blood glucose, urea, alkaline phosphatase (ALP), aspartate aminotransferase (AST), and alanine transaminase (ALT) concentration among the three treatments. Ca, and P levels in blood plasma were also identical among the three groups. The digestibility of Ca was increased significantly (p = 0.01) in FCSP (T1)- and CSCP (T2)-treated calves compared to control (T0) calves. Similarly, T1 and T2 enhanced P digestibility compared to T0. This first report with short-term experimentation depicted some promising scope for the use of locally available conch shell powder (fresh or calcined form) as a potential source of Ca for feeding to livestock, because these new sources of Ca did not affect intake, digestibility of Ca and P, growth performance, blood chemistry, and liver enzymes negatively in weaned crossbred calves.

海螺壳(Turbinella pyrum)粉:生长中的杂交犊牛钙和一些微量元素的潜在海洋生物来源。
本研究旨在评估在杂交犊牛日粮中添加海螺壳粉(新鲜或煅烧)作为海洋有机钙源对泽西岛杂交犊牛生长过程中自愿摄入量、生长性能和血液生化指标的影响。对 15 头泽西杂交雌性小牛(平均体重 70.68 ± 2.90 千克;平均年龄 197.73 ± 12.40 天)进行了为期 90 天的生长试验,平均分为三组,每组 5 头,即对照组(T0)、处理 1 组(T1)和处理 2 组(T2)。所有犊牛均饲喂由精料混合物、糠化稻草和青饲料按 DM 40:30:30 的比例配制的全混合饲料(TMR)。对照组的犊牛饲喂含有标准矿物质混合物的全混合饲料,其中磷酸二钙(DCP)是钙源。T1 组的犊牛饲喂含有新鲜海螺壳粉末(FCSP)的 TMR,T2 组的犊牛饲喂含有海螺壳煅烧粉末(CSCP)作为钙源的 TMR。我们观察到,T1 和 T2 日粮中的钙含量增加了 11.66%(p 0),可视为理想的犊牛日粮。与 T0 相比,T1 和 T2 组犊牛的 DM 和 CP 消费量明显增加(p 0.75)。然而,与 T0 相比,T1 和 T2 组自愿摄入量的增加并没有转化为体重增加(千克)和饲料转化率(千克 DMI/千克增重)的增加。我们观察到三种处理的血糖、尿素、碱性磷酸酶(ALP)、天门冬氨酸氨基转移酶(AST)和丙氨酸转氨酶(ALT)浓度相似。三组血浆中钙和磷的含量也相同。与对照组(T0)相比,FCSP(T1)和CSCP(T2)处理的犊牛对钙的消化率明显提高(p = 0.01)。同样,与 T0 相比,T1 和 T2 提高了 P 的消化率。这份首次短期实验报告为利用当地海螺壳粉末(新鲜或煅烧形式)作为钙的潜在来源喂养牲畜描绘了前景广阔的前景,因为这些新的钙来源不会对断奶杂交犊牛的摄入量、钙和磷的消化率、生长性能、血液化学和肝酶产生负面影响。

期刊介绍: Biological Trace Element Research provides a much-needed central forum for the emergent, interdisciplinary field of research on the biological, environmental, and biomedical roles of trace elements. Rather than confine itself to biochemistry, the journal emphasizes the integrative aspects of trace metal research in all appropriate fields, publishing human and animal nutritional studies devoted to the fundamental chemistry and biochemistry at issue as well as to the elucidation of the relevant aspects of preventive medicine, epidemiology, clinical chemistry, agriculture, endocrinology, animal science, pharmacology, microbiology, toxicology, virology, marine biology, sensory physiology, developmental biology, and related fields.
