Çörek Otunun (Nigella Sativa) Pırlak Kuzularda Besi Performansı Üzerine Etkisi

Abstract

This study was carried out for the purpose of determining the effect of black cumin (Nigella Sativa) on body weight, feed consumption, feed convertion ration, antioxidant capacity of blood serum , and the levels of total protein, ph and urea levels in the rumen. For the research, totally 5 group was formed including 6 lambs in each. During the resarch to the ratios of one of the experiment groups (control) was not given black cumin and to the other groups black cumin was given with the ratios of 1 %, 2 % , 3 %, 4 % respectively. In the groups there were 30 lambs aging from 12 to 14 weeks. The research lasted 8 weeks. For the diets as roughage alfalfa hay was used. Water and feeds was given ad libitum. The lambs were weighed weekly to determine their body weight performance. Feed consumption were weighed daily. The lambs were exposed to the group feeding. At he end of the trial samples of blood and rumen liquid were taken. The mean body weight gain were found as 325.0, 320.3, 312.8, 324.2, 323.8 respectively in the control and experiment groups. It was found that these numbers have no significant statistically. With the use of black cumin to the level of 4 % in pirlak lambs diets, no negative effect was seen between proportions of feed convertion ratio and the values of parametres in blood serum; total protein, urea, and antioxidant capacity, rumen liquid urea valuses. On the other hand when the value of rumen ph values were compared with the control group it was found that it increased ( P < 0.05) . As a result it was found that the use of black cumin to the level of 4 % for the feed convertion ratio of lambs had no negative effect on the body weight gain of specific blood parametres. Even it could be said that the use of black cumin had positive effect by increasing ph value of rumen liquid against the problem of acidose which causes the ruminants that were fed with concantrated feeding negative effects.
