The impact on the productive and reproductive qualities of geese by feeding sprouted grains of different cereals
The aim of our research was investigated the impact on the productive and reproductive qualities of geese by feeding sprouted grains of different cereals.
On the basis of these experiment found out that the research groups of geese had the best development of the reproductive organs, biger live weight, intensevly digested nutrients of feed. So, after the formation of groups experiment at the age of 180 days and start raising geese daylight from 8 to 10 hours of daylight in the second experimental group was the first egg at the age of 206 days, the third group – for two days earlier – at 204 days, while the control group – at the age of 211 days.
During the first month of performance in the third experimental group, which is fed sprouted grain oats, received 2,7 eggs on average laying hen, while the control group – 2,4 eggs. The difference in favor of the experimental group was observed in the following months performance.
Thus, top of the performance in all groups experiment accounts for the third month in a productive period. In this case, upon receipt of the control group – 9,4 eggs in two and three experimental groups were received on 1,8-2,4 eggs more. Dynamics of eggs receiption in groups shows that in the groups at feeding experiment sprouted grains by the average number of eggs laying hens and in subsequent months was higher compared to the control group.
The efficiency of using sprouted grains to normalize the physiological activity confirmed by researches of reproductive females one month from the beginning of a productive period. Namely in 210 day age from each experiment group was scored by 3 female head, from which explored the development of their reproductive organs.
The analyzed indicators show better development reproductive organs of the research groups of geese at this age. Thus, the length of the oviduct in geese of the third experimental group was advanced by 1,9%, more weight oviduct – by 1,8 % and ovarian – by 2,1 % compared with the control group. The second research group exceeded these indicators on control by 0,5; 1,1; 1,4%.
Significant influence of feeding sprouted barley and oats was on reproductive ability of geese, which contributed to obtaining the best fertility of eggs in research groups (88,2-89,4%) compared with the control group (87,7%). This contributed to higher output derivability eggs and goslings that were in the experimental groups higher on 1,6-2,3% and 0,6-1,7% in comparison with the control group.
The weighting results of geese breeder at the beginning of the experiment and at the end of productive period shown that the same live weight at the beginning of a productive period in all groups at the end of the experiment productive period geese live weight tended to decrease, due to high egg productivity females . But live weight of females from research groups was a slight excess in comparison with the control group.
At the same time, the live weight of males geese at the end of productive period increase and experimental groups dominated geese control group respectively by 129-164 g But the difference was in the probable.
According to the results of a 5-month productive period of the control group, which feed only dry mixed feed, received 5447 eggs, while the 2 nd experimental group, which is fed during the period of the experiment sprouted barley in an amount of 30 g per head/day were obtained for 321 eggs more. The highest total yield of – 6104 eggs were obtained in the 3rd experimental group, which sprouted oats fed in an amount of 30 g per head/day, which was significantly (at P≤0,05) than the control group to 657 eggs.
Research groups exceeded the control group both in the average egg laying hen and eggs by weight. Thus, the mass of eggs for research groups were relatively higher by 2,1-6,6 g in the control group. During the experiment the safety of livestock was on 0,5-0,9% higher in the experimental groups compared to the control.
Thus, on the basis of these researches we can conclude the feasibility of feeding sprouted grain cereals poultry, since the fiber structure varies germination of grain, improved digestibility of feed, which increases the availability of nutrients and changes the microbial populations in the gut of poultry. Such positive changes taking place throughout the productive period, enhance the productive and reproductive characteristics of poultry.
