Blood Metabolic Profile of Lambs Fed Complete Diet Supplemented with Exogenous Fibrolytic Enzymes Cocktail

Abstract

Blood metabolic profile (BMP) serve as clinical indicators for the impact of dietary manipulations on physiological health status. The present study was undertaken with the aim to assess the effect of in-feed supplementation of exogenous fibrolytic enzymes (EFE) cocktail as feed additive on BMP in lambs. Crossbred lambs (n=12) of 4-6 months age were distributed into two groups of 6 animals each and fed for a period of 90 days followed by 6 days metabolism trial. Animals in both the groups were offered complete feeds either supplemented with EFE cocktail @ 0.6% DM (Enz) or without any supplementation as control (Con). Haemato-biochemical parameters of animals in both the groups at start (0d) and subsequently at monthly intervals (30, 60 and 90d) were investigated. The EFE supplementation had positive significant (p<0.05) effect on dietary digestible energy content as well as total digestible nutrient intake (g/d) compared to control. However, there were non-significant (p>0.05) effects of EFE supplementation on overall means of all blood cell indices except mean platelet volume (p<0.05) and platelet percent (p<0.01), energy metabolic profile, serum lipid profiles except low-density lipoprotein cholesterol (p<0.05) and atherogenic index (p<0.01), and hepato-renal functioning test profiles. The BMP of EFE supplemented lambs revealed better physiological health status compared to un-supplemented animals. It is concluded that inclusion of EFE cocktail in complete diets for lambs have no adverse effects on the haemato-biochemical parameter suggesting in-feed supplementation of the EFE to improve animals's health conditions for successfully raising lambs intensively.

Inclusion of Yerba Mate (Ilex paraguariensis) Extract in the Diet of Growing Lambs: Effects on Blood Parameters, Animal Performance, and Carcass Traits

“…Most of the blood count parameters were not affected by the treatment, except for some WBC parameters. The same response was observed by Beigh et al [37] in their study with lambs fed a cocktail of exogenous fibrolytic enzymes and/or Artemisia absinthium L. (known as wormwood herb), and by Morsy et al [38], who used red propolis extract with antioxidant characteristics to feed Santa Ines ewes; their results showed that the extract or even the plant itself in the diet increased the number of leukocyte counts.…”

The Hematological and Blood Chemical Parameters of the Female Fat Tail Sheep Raised with Fermented Complete Feed Management

“…The RBC level of the sheep in the study was 12.11±2.18 (x10 6 /µL), which was still in the normal limit according to the textbook (Byers and Kramer, 2010) that was 9.00-15.00 x10 6 /µL. It was consistent with the study of the sheep with CF supplementation in Exogenous Fibrinolytic Enzymes Cocktail (Beigh et al, 2018). The hemoglobin parameter of the sheep in the study were 12.40±1.96 (g/dL), which was consistent with the textbook was 9.00-15.00 g/dL (Byers and Kramer, 2010) and it was corroborated by Anbarasu et al(2002) who conducted a study of the sheep with the basal feed of wheat straw (10.50 to 11.62 g/dL).…”

“…The MCV parameter of the sheep in the study was 30.46±3.38 fL that was considered to be in the normal limit of the textbook parameter (Byers and Kramer, 2010) at level 28.00-40.00 fL and consistent with the MCV of the sheep reported by Saeed et al(2019), which was at the level of 29.40±0.33 fL and also the MCV of the sheep with the CF supplemented with Exogenous Fibrinolytic Enzymes Cocktail, which was at the level of 27.00±0.25 fL (Beigh et al, 2018). The normal MCV parameter of the sheep in the study was consistent with the study of the sheep fed with Moringa oleifera leaf meal by (Jiwuba et al, 2016).…”

“…It is necessary in breeding the sheep to establish a standard reference for their health status. Blood profile is the most important information in establishing an animal's health status, nutrition status, the diagnosis and the prognosis of metabolic disorders, and monitoring the medical treatment progress of the animal (Beigh et al, 2018). The determinant factor of blood profile variation is feed (Ghani et al, 2016), while the determinant factor of the success in animal breeding is also fed (Hastuti et al, 2011).…”

Evaluation of Growth Performance, Blood Metabolites and Gene Expression Analysis in Egyptian Sheep Breeds, in Relation to Age

“…Measuring of gene expression and blood metabolites levels is a reliable method for evaluation sheep growth performance and health status in addition to it is a useful way for judging of individual animal physiological status, diagnosis of metabolic disorders, clinical nutritional balances, deficit condition, treatment monitoring and prognostics (Nath et al, 2014;Beigh et al, 2018). The mortality of pre-and post-weaning lambs, lower growth rates, and lack of feed are major problems facing most sheep farmers and they are main factors which have a negative effect on total productivity in sheep husbandry and represents an economic loss (Saleem et al, 2017;Elshazly and Youngs, 2019).…”
