XOLJIGITOV. Chetdan keltirilgan nemis seleksiyasiga mansub golshtin zotli sigirlarni oziqlantirish
Abstract
Tajriba uchun Germaniya davlatidan olib kelingan 3-4-oylik bo‘g‘ozlikdagi nemis seleksiyasiga mansub sigir- lardan 30 boshi vazniga ko‘ra 3 guruhga bo‘lib, har guruhga 10 boshdan tanlab olindi. Sigirlar tuqqanidan 10 kun o‘tib, ya`ni og‘iz sutidan chiqib asosiy sutga o‘tgandan so‘ng I-guruh AR+10% asosiy ratsionni umumiy to‘yimliligini 10 % ga, II guruh AR+15 % ga oziqa ratsioni to‘yimliligini oshrish asosida III guruh AR xo‘jalikdagi mavjud oziqalar oziqlantrish ratsioni bo‘yi- cha oziqlantirildi. Tajribadagi III guruh sigirlariga o‘rtacha 18,43 kg EOB sarflanib, tengqurlari I guruh sigirlariga nisbatan 9,03% ga, II guruhga mansub sigirlar esa tengqurlaridan 13,35% ga kam bo‘ldi. Oziqlantirish ratsionida quruq modda III guruhda 2020 g tashkil qilib, I guruh 10.22 5%, II guruh 12,93 % ortiqcha quruq modda sarfladi. Oziqlantirish ratsioni tarkibida hazmlanuvchi protein I guruh sigirlari III guruh tengdoshlariga nisbatan 8,9 %, II guruh sigirlari esa 12 % oratiqcha sarflandi. Kalit so‘zlar: omuxta em, sut va go‘sht , sersut qilishda, sut yog, sut oqsil, EOB, oziqa birligi, quruq modda. Abstract. For the experiment, 30 cows of German selection, imported from Germany, aged 3-4 months, were divided into 3 groups according to their weight, and 10 cows were selected for each group. On the 10th day after calving, i.e., after transition- ing from colostrum to main milk, Group I was fed according to the existing feeding ration of the farm, based on an increase in the total nutritional value of the main ration AR+10% by 10%, and Group II by AR+15%. Cows in Group III of the experiment consumed an average of 18.43 kg of EOB, which is 9.03% less than cows in Group I and 13.35% less than cows in Group II. The dry matter content in the feeding ration in group III was 2020 g, with group I consuming 10.22%, while group II consumed 12.93% of excess dry matter. Digestible protein in the diet of cows in group I was 8.9% more than in cows in group III, and in cows in group II it was 12% more.
