Tissue structure observation of internal organs and skin of Whitmania pigra;

The weight of 14 internal organs of Avine breeder hens were examined in growth period (5～25w).

This experiment used 24 Sujiang gilts,respectively,in the newborn,15,30,45,60,75 four days of the slaughter,the determination of its heart,liver,lung,spleen,stomach,kidney weight to analyze the internal organs of the early the development of the law.

This experiment was conducted by an intraperitoneal injection of a flooding dose of L-Phenylalanine to investigate the effect of dietary starch sources on the fractional protein synthesis rates(FSR) in visceral organs of weaned piglets.

The visceral organs growth curves were analyzed on Cherry valley ducks from 1 to 7 weeks old,and fitted with non-lineared model of Gompertz.

The weights of the visceral organs were measured.

5 kg each,were used in a 2×2 factorial design experiment to determine the effect of urease inhibitor and roughage diets on growth performance and internal organ in fattening sheep.

AVAIN cs broilers were fed as usual and used to study the growth regularity of the internal organs.

In this paper,by studying the weight and water content of internal organs of gerbils in different sex,we have come up with the result:The weight of body in male gerbils is heavier than that in females; and the relative weight of mostly internal organs of males is lighter than that in females; the weight and the water content of internal organs show no distinct change between the different sex.
