Abstract

This study aimed to assess the effect of rice green folder on growth performance in Khmer native x Hariana crossbred cattle. Twelve males of Khmer native x Harian crossbred cattle were assigned an initial body weight of 190±10 kg (IBW) with 62 days of feeding regimen and an average of 15 months of age. The dietary treatments were assigned in a completely randomized design (CRD), with three treatments of four replications, each containing four cows. Feeding treatments were as follows: 1) 100% commercial feed (Control), 2) 50% commercial feed + 50% natural grasses (NG-50), and 3) 50% commercial feed + 50% rice green folder (RGF-50). Cows were fed at 1.5% Body weight of dry matter (DM). The results indeed showed that the initial body weight (IBW) and final body weight (FBW) were non-significantly different (P>0.05). The Control group consumed the total feed intake between the groups NG-50 at 6.58 kg and 6.85 kg, which were similar amounts but higher than RGF-50, which was 5.79 kg daily a head (linear increased <0.05). Nevertheless, average daily gain (ADG) in Control, NG-50, and RGF-50 was linearly increased (P<0.05) as the ADG was 0.58, 0.46, and 0.39kg/head. FCR in the NG-50 and RGF-50 were in the same row and higher than Control, with the precious value in both NG-50 and RGF-50 at 14.90 higher than 11.45 Control (P<0.001).  In conclusion, RGF-50 was a suitable roughage supply for feedlot cattle and could improve economic effectiveness. Thus, RGF was recommended for further study.

Abstract

Bemisia tabaci is a major pest of soybeans and a vector of plant viruses. This study aimed to evaluate and compare the efficacy of four entomopathogenic fungi for suppressing B. tabaci populations on soybeans. The four treatments were L. lecanii, A. aleyrodis, M. anisopliae, and B. bassiana, a comparison with the insecticide thiamethoxam and a control group without treatment. The four types tested were able to suppress B. tabaci populations by up to 75%, with A. aleyrodis being especially effective. There was no significant difference in efficacy between the four types and the insecticide thiamethoxam. Validating the efficacy of entomopathogenic fungi, there were no significant differences in plant height, dry stover weight, or number of pods between treatments with the insecticide thiamethoxam. However, significant differences occurred in the number of empty pods and seed weight, reducing yield losses by up to 78%. There was a positive correlation between the B. tabaci population and the number of empty pods (r = 0.80), while there was a negative correlation between the B. tabaci population and plant height and soybean yield (r = -0.56 and r = -0.54, respectively).
