Effects Of Cysteamine And Diludine On Performance And Meat Quality In Finishing Pigs

The effects of Cysteamine (CS) and Diludine on performance, neurohormone and endocrine hormone, protein and carcass characteristics were studied in finishing pigs. One hundred and sixty Duroc×Landrace-Yorkshine finishing pigs of original average weight 65.08±6.99kg were divided into four groups with four replicates, each of which including 10 pigs,in a randomized block design. The four groups were respectively fed corn-soybean basic diet (group CT), containing 120mg/kg CS (group CS), containing 30mg/kg Diludine (group Dilu.), containing 120mg/kg CS and 30mg/kg Diludine (group CS+Dilu.). The result as follows:⑴Average daily gain (ADG) and average daily feed intake (ADFI) in group CS and group Dilu.were higher than that in group CT,that group CS+Dilu. was higher than that in group CT (P﹥0.05),feed/gain(F/G)in group CS+Dilu. was lower than that in group CT (P﹥0.05).⑵The content of blood urea nitrogen (BUN) and blood glucose (GLU) in group CS+Dilu. were lower than that in group CT (P﹥0.05).⑶Compared with the group CT, the group CS+Dilu. tended to decrease the content of serum T3 and T4 (0.05﹤P﹤0.1),decreased significant the content of Cortisol (Cor.)(P﹤0.01), decrease the content of serum growth hormone(GH), Somatostatin(SS), glutamate pyruvate transaminase(GPT), thyroid stimulating hormone (TSH) (P﹥0.05).⑷Compared with the group CT, Group CS+Dilu. had significant decreased the backfat thickness and skin thickness (P﹤0.05), increased marbling, meatcolor, decreased tenderness, drip loss.
