光色对家禽的影响

一光色的作用机理 1 光的作用机理一般认为,光的作用机理是光信息通过眼球内的`光受体-视网膜节细胞-传递到视觉中枢,或者通过下丘脑内的光受体而被感知,并将光信息转化为生物信号,进而影响垂体一性腺轴释放激素来调节机体的生长发育、生产性能、生殖功能和行为活动.

篇2：饲料纤维对家禽生产的影响

饲料纤维对家禽生产的影响

饲料中的`粗纤维可在动物的盲肠、结肠以及反刍动物瘤胃中经微生物发酵产生复合蛋白供作能源,但其利用率常受到木质素的影响.通常认为粗纤维是供反刍动物利用的,不应在家禽饲粮中占主要部分,因饲粮中纤维含量越少,其饲喂快速生长家禽的潜力就越大.

篇3：花生四烯酸对家禽卵泡颗粒细胞的影响

花生四烯酸对家禽卵泡颗粒细胞的影响

花生四烯酸是一类顺式多不饱和脂肪酸,是动物细胞膜磷脂的重要组成部分.在家禽生产中,花生四烯酸作为一种必需脂肪酸调控家禽的.生长发育;而且作为功能性营养因子,通过在禽蛋中的蓄积来满足人体需求.除了作为前列腺素合成的前体物调节动物生殖过程外,花生四烯酸在调节卵泡颗粒细胞功能的过程中也起重要作用.

篇5：科技进步对社会发展影响

科技进步对社会发展影响

21st century is the century of technology. Nowadays, technology is everywhere around us. The development of technology has a significant affact toward the society. Several technologies that we usually use are the internet, computer, and cellphone. These new technologies make our life much easier and better.

First, the development of computer changes our life. Decades ago, people needed to do lots of complex calculation on hand because they did not have computer, and more obvious, they did not have the software for calculation. As the result of that, people spent hours on the equations that a computer can solve in just a minute. Since the development of computer, people are able to use some kind of software to compute lots of complex functions and mathematical calculation. Computer becomes the most helpful equipment for the sciencists because they can use their time more efficiently.

Also, internet is another useful tool for us today. The development of internet brings a great impact toward the society. Instead of going to library and fliping all the books to figure out some information, we can just simply use a mouse and click on the website to do research. The internet leads us to a place where we can find unlimited information and resources. It makes our life much easier and better.

The last technology is cellphone. Nowadays, many people have a cellphone. But it just appears on the market for about 10 years. It is very convenience to the users because we can talk to anyone we want with a phone as small as a wallet. Also, we can communicate with others by making a phone call instead of sending letters. It is very fast and useful way to communicate.

In conclusion, I believe the development of technology brings significant impact to our life. It is very helpful to us and I believe technology will keep improving in future.

I HOPE IT HELPS!
