Проводились предварительные исследования эффективности прибавки 3 видов кормов в дополнительном кормлении ягнят горной овцы содержимых на пастбище, в частности: стандартного комбикорма CJ, ячменя и сушеной кукурузы. Среди этих кормов только ячмень производится в данном районе. Целью исследований было улучшение эффективности пастбищного содержания путем потребления питательных веществ зеленого корма...
East-Friesian ewes of the meat-type sheep and their feminine F₁ progeny after the Polish Merino rams and Wielkopolska ewes were tested.The experimental material constituted Polish Merino and Wielkopolska ewes. The East-Friesian ewes reached a very high level of the wool performance and a high body weight and their reproductive utilization was higher than in sheep of the same breed maintained irder...
От ярок покрытых в 10-месячном возрасте были получены ягнята овечки оцениваемые в четырех группах: I - каменецкая овца (длинношерстная) , II - помеси каменецкой овцы с баранами черноголовой породы, III - помеси Черноголовки с баранами каменецкой овцы, IУ -черноголовая пррода. Розницы в весе тела в 3- и 6-месячном возрасте не были существенными. Однако наиболее тяжелыми были овцематки группы II (22,40...
Соответствующие исследования проводились на 50 овцематках польской мериносовой породы, в том числе на 40 овцематках выращивающих одинцы н 10 овцематках выращивающих близнецы в овчарне Собеюхы. На основании 7 контрольных уроев при использовании синтетического окситоцина определяли молочность овец в отдельных стадиех лахтации. Продукция молока, жира и белка была выше у овец с близнецами, чем с одинцами...
The respective experiment was carried out on 56 ram-lambs of four genotypes: Polish lowland sheep, F₁ crosses ♀ Polish lowland sheep x ♂ Polish fur-cloak sheep („wrosówka"), purebred Polish full-cloak sheep and Finnish sheep. After weaning the ram-lambs were fed in two feeding groups differing with the protein and crude fibre content. Lambs were weighed throughout the whole rearing and fattening...
Observations on performance of 98 Merino ewes depending on the maintenance conditions: under roof (Z), in the littered sheepyard (O) as well as on the mating and shearing date - group 1: mating December 1-15, shearing September; group 2: December 16-January 31 and April, respectively, were performed. No stronger effect of the maintenance conditions on the body weight and reproductive utilization indices...
The aim of the respective investigations was to compare the effect of intensive feeding of lowland sheep ewes with silage and meadow hay as well as with green fodder of alfalfa and concentrated feeds on the reproduction indices. The experiment was carried out in the period July 26 - October 23, 1984 on 120 ewes divided into 4 feeding groups (by 30 ewes in each group). Ewes of the groups I, II and...
