Effects Of Supplemental Feeding On Growth And Development Of Nursing Foals Of Hazah Horses And Yili Horses

The objects of this research were nursing foals of Kazak horses in Tekes County and nursing foals of Yili horses in Zhaosu County. This research project mainly studied the influence of supplemental feedings on the growth and development of nursing foals. This project provides a reference for feeding techniques and methods for nursing foals as they relate to production and application.Experiment I:Thirty,90±10day old nursing foals of Kazak horses, were randomly divided into three groups according to weight, and other guidelines. Each group had10foals.(The groups will hereafter be referred to as the control group, experimental group I and experimental group â…¡). The control group foals were not fed any supplemental feedings, experimental group I foals were fed feeding Complement feed1(without the addition of lysine), experimental group II foals were fed feeding Complement feed2(0.25%lysine). The foals of the feeding groups were fed a complement of supplemental feed—0.6kg per100kg of body weight. They were fed twice-daily feedings, the same amount at each feed. The period of the experiment was80days. The day before and after the experiment with12hour of fasting.they were weighed and their body sizes were measured.The result showed that the average daily gain of the experimental group â…  and experimental group â…¡ compared with the control group respectively increased by50%(P<0.01) and61.53%(P<0.01);Experimental group â…  and experimental group â…¡ foals had a greater increase in withers height, body length, Chest circumference than in the control group. They increased by32.85%(P>0.05),13.22%(P>0.05),49.20%(P<0.01) and40%(P>0.05),14.23%(P>0.05),57.21%(P<0.01); Experimental group I and experimental group II foals exhibited no real significant difference to the control group in the cannon circumference (P>0.05); Daily gain and body size of the experimental group II foals showed faster growth than experimental group â…  ({P>0.05).Experiment II:Fifteen,90±10day old nursing foals of Yili horses, were randomly divided into three groups according to weight, and other guidelines. Each group had5foals.(The groups will hereafter be referred to as the control group, experimental group â…  and experimental group â…¡.) The control group foals were not fed any supplemental feedings, experimental group â…  foals were fed feeding Complement feed1(without the addition of lysine), experimental group II foals were fed feeding Complement feed2(0.25%lysine). The foals of the feeding groups were fed a complement of supplemental feed—0.6kg per100kg of body weight. They were fed twice-daily feedings, the same amount at each feed. The period of the experiment was45days. The day before the start and after the end of experimentwith12hour of fasting, they were weighed and their body sizes were measured;At the end of the experiment, in the next morning, fasting blood samples were collected from the jugular vein. Four days before the end of the experiment horse manure samples were continuously acquired and-20℃cryopreservation was applied. The following determination indicators were studied:blood plasma free amino acids, plasma biochemical parameters, minerals, vitamin E, coenzyme Q10content and horse manure starch content. The results showed that the average daily gain of experimental group â…  and experimental group â…¡ compared with the control group respectively increased by18.27%(P>0.05)å'Œ25.56%(P<0.05); Experimental group â…  and experimental group â…¡ foals had a greater increase in withers height, body length, Chest circumference and cannon circumference than the control group. They increased by47.37%(P>0.05),48%(P<0.05),36.85%(P>0.05),77.17%(P>0.05) and71.05%(P<0.05),56%(P<0.05),55.52%(P<0.05) and63.04%(P>0.05). The result showed that the daily gain and body size of the experimental group â…¡ foals increased faster than the experimental group â…  foals (P>0.05); Experimental group â…  and experimental group â…¡ foals were higher in plasma glucose,plasma biochemical parameters, vitamin E and coenzyme Q10 content than the control group, but there was no real significant difference between them ((P>0.05). The results showed that supplementary feedings reduced the content of urea nitrogen in blood plasma. Plasma lysine content in experimental group I and experimental group II compared to the control group, respectively increased by39.90%(P<0.05) and61.60%(P<0.05). The lysine content of experimental group II foals’plasma, compared with experimental group I foals’plasma, were higher by15.51%(P>0.05). The other amino acid contents of the two groups were higher than control group, but there was no significant difference (P>0.05). Supplemental feedings had little effect on the plasma mineral elements of foals. The amylopectin and amylose content of the feces of the experimental group I and experimental group II were higher than the control group, with an increase of7.48%(P>0.05),15.19%(P>0.05) and4.41%(P>0.05) and13.82%(P<0.05), respectively. The amylopectin and amylose content of the feces of experimental group I was higher than experimental group â…¡ (P>0.05).The study results show that the complement of feed feeding the experimental design can be improved significantly increase the speed of growth and development of nursing foals of Hazah horse and Yili horse. Compare, adding a0.25%lysine feed supplement was especially effective. Complement the diet containing0.25%lysine better. The feeding can be increase in plasma free amino acids,plasma biochemical parameters, minerals, vitamin E and coenzyme Q10content. Foals to complement feed starch have a higher digestibility.
