The yield among different treatments manifested that: MNPK>MNK>NPK>MN>NP>N>CK. The main measure to enhance wheat yield is using fertilize ,And the nutrition of N is at the dominant status. The reason why chicken-dejecta can improve wheat yield is that they take along with some nutrition elements include N,P and K. There are apparent positive mutual domino offects among chicken-deject,N,P and K. Using chicken dejecta together with N,P,K could increase wheat yield and income notability Select The Effect of Ae.kotschyi Cytoplasm on Seed Germination and Seedling Emergence of Wheat Zhan Ke-hui Ren Ya Wang Lian-hua Ma Su-qin Chinese Agricultural Science Bulletin    2003, 19 (6): 55-55.   DOI: 10.11924/j.issn.1000-6850.030655 Abstract + (1655)       PDF (262170KB) (543)       Knowledge map    The sterile lines with Ae.kotschyi cytoplasm (shortened:K-type) and their corresponding preserve lines, restoring lines and hybrids were used in this paper to study the difference in seed germination and seedling emergence between Ae.kotschyi cytoplasm and T.aestivum cytoplasm.

Bunce Chinese Agricultural Science Bulletin    2004, 20 (1): 3-3.   DOI: 10.11924/j.issn.1000-6850.040103 Abstract + (1315)       PDF (137666KB) (636)       Knowledge map    Polychlorinated biphenyls (PCBs) fall into the category of halogenated aromatic compounds (HACs) or dioxin-like compounds (DLCs) and are highly lipophilic environmental contaminants. Metabolism of DLCs generally involves monooxygenase enzymes of the CYP 1A family in which CYP 1A2 specifically exists in hepatocytes and is mainly responsible for much more toxic reactions of xenobiotics. In this work, we have examined the role of numerous PCBs as inhibitors of the demethylation of 7-methoxyresorufin, a process that is selectively catalyzed by CYP1A2. 2,3,7,8-Tetrachlorobenzo-p-dioxin (TCDD), 3,3’,4,4’-tetrachlorobiphenyl (PCB 77) and 3,3’,4,4’,5-pentachlorobiphenyl (PCB 126) were found to be the strongest inhibitors of methoxyresorufin-O-demethylase （MROD） activity, thus accounting for the high ability of hepatic tissue to selectively sequester these compounds.

A high oocyte maturation, fertilization and cleavage rate and a low rate of blastocyst yield and calving following transfer of in vitro produced buffalo embryos have been obtained. The efficiency of IVP in buffalo is much lower than that in cattle. Several problems need to be resolved before IVP technology can be used regularly in buffalo breeding. This review attempts to present an overview of the different techniques used in buffalo to produce transferable embryos in vitro, namely in vitro maturation and fertilization of immature oocytes and in vitro development of the resulting cleaved embryos to the blastocyst stage before transfer. The problems associated with IVP and the possible solutions discussed.

And after breeding，the conception rate separately was 38.75% and 41.67%. This results showed that the postnatal high～yield dairy cattle was treated by the postnatal colostrums of 1 hour , the heating rate was higher than that of colostrums of 24 hour (P<0.05). The difference was not remarkable (P>0.05) between the postnatal colostrums of 1 hour and 24 hour for the conception rate. To the heating rate and conception rate, the effects of the postnatal colostrums of 1 hour was same as that of the tris～hormone(P>0.05).

According to sex, we divide them into two groups. Then we measure their body length, height at wither, breast depth, breast circumstance, hip with and weight, and analysis them. The results show: At 1.5 years old, the hormone level of GH and INS appear difference unremarkably (p>0.05). At 2.0 years old, the hormone level of GH and INS appear difference remarkably (p<0.05). And with the age growing, the GH level appear to descend while INS level appear to ascend. INS and GH level present negative correlation clearly (p>0.05). Analyzing the body composition index, we discovery at 2.0 year old QinChuan Cattle’ breast circumstance is wider , hip grows clearly, body growth rate is relatively slow. But growth rate of muscle is relatively quick. It correspond with the meat cattle growth rules and middle maturity or late maturity characters of Qinchuan Cattle. Comparing the actual weight with partition standard of economic performance, we discovery Qinchuan Catttle still belongs to beef and farm breed. But with present selecting and cultivating present years, Qinchuan Cattle’s weight add greatly.
