Extended Abstract
Introduction and Objective: Ensiling total mixed ration can be used as a sustainable alternative to efficiently of feed management, improves digestibility and increase performance of ruminants. The objective of this study was to determine the effects of using total mixed ration silage based fodder corn on the growth performance of fattening Zell lambs.
Materials and Methods: Fourteen Zell male lambs (19.74± 2.07 kg BW) were randomly allocated to one of two experimental diets similar in nutrient contents. Experimental diets included control diet based on alfalfa and wheat straw (CD) plus concentrate and total mixed ration silage based on fodder corn plus concentrate (TMRS). The animals were fed three times daily in three equal portions over a 12-weeks assay following a 2-weeks adaptation period. Lambs were weighed immediately before the morning feeding at the beginning and at 3-weeks intervals. At the end of fattening period, the lambs were housed in individual cages to evaluate nutrient digestibility of the experimental diets. Furthermore, blood samples were collected from the Jugular veins of the lambs for measuring of glucose, total protein, albumin and liver enzymes such as alanine aminotransferase (ALT) and aspartate transaminase (AST).
Results: Average feed intake was not affected by the experimental diets, but final body weight, total body weight gain, average daily gain were greater but the feed conversion ratio (feed/gain) was lower in lambs fed TMRS diet than those received CD diet (P<0.05). Digestibility of dry matter, organic matter and neutral detergent fiber were higher (p<0.02) in CD diet that that of the TMRS diet. There was no difference in plasma concentration of albumin, total protein, glucose, ALT and AST between the experimental groups, and all of those parameters were within the normal range for healthy sheep.
Conclusion: It was concluded that ensiling total mixed ration based on the fodder corn was associated with an optimal fermentation and using its in fattening Zell lamb diets caused an increase in final body weight and daily gain, and improved feed conversion ratio. Therefore, ensiling total mixed ration could an appropriate feeing management to improve performance of fattening lambs.
