Casein is a family of milk proteins that exists in several molecular forms and is the main protein present inthe bovine milk. The B variant of bovine k-casein is reported to be favorable for quality and quantity of cheese derived from milk and considered to be included in breeding strategies of dairy cattle. Genotypes of72 Russian Black Pied and 80 Red Pied cows were determined for ...
a total of 125 russian red pied cows were genotyped for the prolactim-related gene. the prl-rsai genotypes were analysed using the polymerase chain reaction -restriction fragment length polymorphism (pcr-rflp) method. in this breed, the frequencies of alleles were as follows; a= 0.794 and b= 0.206. the frequencies of aa, ab and bb genotypes were 0.598, 0.392 and 0.01; respectively. results sho...
In this paper we argue for the existence of covert pied-piping in wh-questions through a previously unnoticed pattern of intervention effects in superiorityobeying English multiple wh-questions. We show that the preference of covert pied-piping is for movement of larger constituents, unlike overt pied-piping. We argue that this discrepancy stems from conflicting requirements of PF and LF: overt...
Maternal investment in offspring immunity via egg quality may be an adaptive evolutionary strategy shaped by natural selection. We investigated how maternal investment in eggs can influence offspring immunity by conducting two experiments. First, we manipulated foraging performance of the mothers before egg laying by attaching a small weight to their back feathers. During the nestling period, w...
The aim of this work was to study bioenergetic and ethological indicators in crossbred first-calf heifers compared purebred heifers. research conducted on the Ukrainian Black-Pied dairy breed first-generation crossbreeds obtained as a result crossing with Brown Swiss breed, well as, Red-Pied Montbéliarde breed. Black-and prevailed over crossbreed indicator milk yield for 305 days lactation by 1...
Hybrid resequencing of the antibacterial innate immune genes coding for toll-like receptors, namely TLR1, TLR2, TLR4, TLR5, and TLR6, using HiSeq PacBio technologies pooled population samples Czech Simmental (Czech Red) cattle allowed us to determine haplotypes formed by polymorphisms present. Directly determined within range large proximal amplicon in TLR2 two clusters network tree graph. The ...
Climate change could affect resource competition between resident and migratory bird species by changing the interval between their onsets of breeding or by altering their population densities. We studied interspecific nest-hole competition between resident great tits and migrant pied flycatchers in South-Western Finland over the past five decades (1953-2005). We found that appearance of fatal ...
