Productive Performance of Lactating Buffaloes Fed Ration Containing Sugar Beet Tops and Corn Silages
Sixteen multiparous lactating buffaloes after 8 weeks of calving and weighing 500 to 600 kg were used in a complete switch-back design with four groups. Buffaloes in the first group were fed the control ration (R1) consisted of DM basis of 60% concentrate feed mixture (CFM)+20% rice straw (RS)+20% berseem hay (BH), while in the other groups the rations consisted of DM basis of 40% CFM+20% RS+40% sugar beet tops silage (SBTS) and corn silage (CS) in different ratios; 2:1 (R2), 1:1 (R3) and 1:2 (R4), respectively. The digestibility coefficients of DM, OM, CF, EE and NFE, TDN value and the intake of DM and TDN increased significantly (P<0.05) with increasing the level of corn silage, however, CP digestibility, DCP value and CP and DCP intake increased (P<0.05) with increasing level of sugar beet tops silage in the rations. The pH value and NH3-N concentration increased (P<0.05) with increasing level of sugar beet tops silage, however, TVFA's concentration increased (P<0.05) with increasing level of corn silage in the rations. Buffaloes fed R3 recorded the highest (P<0.05) milk and 7% FCM yield, however, those fed R1, had the lowest yield. The percentages of fat, lactose and TS increased (P<0.05) with increasing the level of corn silage, however, the percentages of protein, SNF and ash increased (P<0.05) with increasing the level of sugar beet tops silage in rations. Animals fed R3 showed the lowest amounts of DM and TDN required per kg 7% FCM and R4 the lowest amounts of CP and DCP required per kg 7% FCM, however, those fed R1 revealed the highest amounts (P<0.05).
期刊介绍:
Iranian Journal of Applied Animal Science (IJAS) is an international journal publishing Research Articles (Full-Length Original Scientific Papers), Short Communications and Review on animal sciences, and related areas. The journal covers all related topics of Animal Science. Papers are welcome reporting studies in all aspects of animal science including: - Animal breeding and genetics (such as quantitative and molecular analysis of animal performance, genetic improvement and resources, genetics of physiological process, selection schemes for economic animal improvement, impact on animal health, etc) - Animal feeding and nutrition (such as food intake, digestion, nutrigenomics/nutrient: gene interactions, metabolism and metabolomics, nutritional control of function and performance, feed evaluation and feeding, diet and animal health) - Animal reproduction - Animal biotechnology - Animal physiology and functional biology of systems (such as reproductive and developmental biology, growth, muscle biology, lactation, exercise, product composition etc) - Animal ethology, behavior and welfare (such as social and sexual behavior, animal- man relationships, adaptation, stress, impact of management and environment on health, etc) - Animal products technology - Animal management and economics - Animal products processing and animal by-products - Animal microbiology - Livestock farming systems, environmental impact and climate changes (such as sustainable livestock management systems, whole farm management strategies, animal work, systems modeling, traceability, socio-economic consequences of systems, the impact of animals on biodiversity and landscape and climate changes, etc). - Other related topics (such as engineering, farming and land-use management and to other disciplines in relation to animal science).
