Embodiment 1

[0067] Embodiment 1. Experimental animal, experimental feed and experimental method

Embodiment 1-1

[0068] Example 1-1 Experimental Animals

[0069] In this disclosure, 8 Korean native beef cattle (average 8.3±0.72 months old) were selected and used.

[0070] As shown in Table 2, the initial body weights of the sentinel animals were measured, and the beef cattle were divided into groups of control and NALT-treated groups (0.1% NALT), 4 beef cattle in each group, so that there was no difference between the two. show statistically significant differences.

Embodiment 1-2

[0074] Embodiment 1-2 raises experimental feed

[0075] Antibiotic-free total mixed rations (TMR, Nonghyup Feed Co., Ltd., Yangju-si, Korea) were fed as the basic diet. The chemical composition (moisture, crude protein, crude fat, crude ash, etc.) and amino acids (19 kinds) of the basic diet stored at -20°C were analyzed, and the results are shown in Table 3.

Abstract

The present application relates to a feed additive composition for cattle comprising N-acetyl-L-tryptophan (NALT) and, particularly, to: a feed additive composition for reducing temperature stress of cattle, increasing an average daily gain, and increasing a feed intake, the feed additive composition comprising N-acetyl-L-tryptophan as an active ingredient; a feed comprising the feed additive composition for cattle; and a method for reducing temperature stress of cattle, increasing an average daily gain, and increasing a feed intake, the method comprising the step of feeding cattle with a feed additive composition or feed for cattle comprising N-acetyl-L-tryptophan as an active ingredient.

Description

technical field [0001] The present disclosure relates to a cattle feed additive composition comprising N-acetyl-L-tryptophan (NALT) as an active ingredient, and more particularly, to: a method for reducing temperature stress in cattle, increasing cattle A feed additive composition that increases the average daily weight gain and feed intake of cattle, the feed additive composition includes N-acetyl-L-tryptophan as an active ingredient; a feed additive composition that includes the cattle feed additive composition feed; and methods for reducing temperature stress in cattle, increasing average daily gain in cattle, and increasing feed intake in cattle, the method comprising feeding cattle containing N-acetyl-L-tryptophan as an effective Ingredient feed additive composition or feed for cattle. Background technique [0002] The thermal environment is very important compared to other environments because it directly affects the homeostasis of warm-blooded cattle. The thermal en...
