Egg Brother purpose: use simple language to help chicken friends, improve chicken production technology, and solve substantive problems!
Recently, some egg friends have asked in a private message which layer chicken breed is good and what is the difference between Highland brown and Roman brown, and wants to introduce its advantages and disadvantages. Experienced farmers know that Hyland brown and Roman brown are high-yielding layer chickens, which are imported varieties of American Highland and German Roman, respectively, and egg lovers who have raised eggs may find that there is a certain difference in their production. The following combines the production indicators of Hyland brown and Roman brown, compares the level of its production performance, and hopes to provide some reference for chicken novices.
<h1 class="pgc-h-arrow-right" > First, understand the common advantages and disadvantages of lower Hyland brown and Roman brown:</h1>
Advantages of Hyland brown and roman brown:
Temperament is docile and has low sensitivity to stress.
It is large and hardy in winter.
Eggs are heavy, breakage rates are low, and egg production is high.
The survival rate is relatively high (compared to powder-shelled layer chickens).
Disadvantages of Hyland brown and roman brown:
The body is large, and the number of feedings per unit area is small.
The amount of food intake is high, and there is a tendency to be fattened, which will affect the egg laying performance in the later stage.
Large, the summer heat of the flock is poor.
<h1 class= "pgc-h-arrow-right" > secondly, the main production indicators of Hyland brown and Roman brown were analyzed</h1>
(1) The main production performance indicators of Highland brown layer chicken
Growing period (0 to 17 weeks old):
Survival rate: 98%
Average weight at 17 weeks: 1.40 to 1.48 kg
Feed consumption from 0 to 17 weeks of age: 6 kg
Egg laying period (18 to 72 weeks old):
Day-old with an egg laying rate of 50%: 146 days old
Peak egg production rate: 94% to 96%
The total number of eggs laid by 72-week-old laying hens (per chicken): 319 to 329
Total egg weight (per chicken) at 72 weeks of age in trotting layers: 19.7 kg
Average daily consumption (per chicken) of 18-72 weeks of age: 105 grams to 112 grams
Average feed-to-egg ratio of 18-72 weeks old: (2.05~2.18):1 (consumes 2.05~2.18 kg of material per 1 kg of egg produced)
Survival rate: 96%
(2) The main production performance indicators of Roman brown layer chicken
Growing season (0 to 20 weeks old)
Survival rate: 97% to 98%
Average weight at 18 weeks: 1.5 to 1.6 kg
Feed consumption: 7.4 ~ 7.8 kg
Egg laying period (19 to 72 weeks old)
50% of the day age of egg production: 146 to 161 days old
Peak egg production rate: 92% to 94%
The total number of eggs laid by 72-week-old laying hens (per chicken) is 320
Total egg weight (per chicken) at 72 weeks of age in troters: 20 kg
Average daily consumption (per chicken) of 19-72 weeks of age: 110 grams to 120 grams
Average feed-to-egg ratio (2.1~2.2):1(Consumes 2.1~2.2 kg of feed per 1 kg of egg produced)
Survival rate: 94-96%
<h1 class = "pgc-h-arrow-right" > Finally, compare the level of the full (0-72 weeks) production index of Hyland brown and Roman brown:</h1>
(1) The survival rate of Hyland brown is 94%, which is slightly higher than that of Roman brown by 91% to 94%.
(2) The total egg production of Hyland brown is 19.7 kg, which is slightly lower than the Roman brown at 20 kg.
(3) The consumption of Hyland brown is 46.4 to 49 kg, which is lower than the consumption of Roman brown of 47.4 to 51.5 kg.
(4) The feed-egg ratio of Hyland Brown during the egg-laying period is (2.05~2.18):1, which is higher than that of Roman Brown (2.1~2.2):1.
(5) The highest yield of Hyland brown is 94%-96%, which is slightly higher than the highest yield of 92%-94% of Roman brown.
In summary, from the four aspects of survival rate, feed-to-egg ratio, material consumption and maximum egg production rate, Highland brown breed layer chickens have a slight advantage.
<h1 class= "pgc-h-arrow-right" > in addition to production indicators, hyland brown and roman brown also have the following differences:</h1>
01 Compared with Hyland brown, Roman brown is more prone to pecking problems.
02 Roman brown's resistance to infectious bronchitis (IB) in chickens is better than hyland brown.
03 Roman brown is also more tolerant to rough feeding, which should be fully considered when selecting varieties.
The above is the comparison of the advantages and disadvantages of the main production performance of Highland brown and Roman brown commercial layer chickens, and provides chicken friends with reference exchanges
