Lucerne (Medicago sativa L. var. Palava), harvested at four successive dates over a 30-day period, was evaluated for chemical composition (dry matter, organic matter, crude protein, ether extract, crude fibre, nitrogen-free extract, neutral detergent fibre, acid detergent fibre, acid detergent lignin), amino acid contents and intestinal digestibility in dairy cows. Dry matter (r = 0.78), organic matter (r = 0.95), crude fibre (r = 0.91), neutral detergent fibre (r = 0.94), acid detergent fibre (r = 0.79) and acid detergent lignin (r = 0.48) presented positive linear correlation coefficients (r)...

The objective of this study was to examine the influence of weight and sex on fat amounts in relation to the formation of selected carcass cuts in final hybrid pigs commonly kept in the Czech Republic. During the experiment 123 hybrid pigs of various genotypes were tested. The pigs were slaughtered at an average weight of 120.4 kg and dissected in detail. The tested pigs were divided into 5 weight categories, while the tissue composition of ham, joint, shoulder and neck was monitored with emphasis on the assessment of IMF content. A decrease in the lean meat proportion was shown, as well as an increasing fat proportion with increasing weight: for the...
N-6 and n-3 fatty acids in different beef adipose tissues depending on the presence or absence of the gene responsible for double-muscling

Levels of n-6 and n-3 PUFAs, including those with 20 and 22 carbon-chains, in concentrate-fed Asturiana de los Valles (AV) yearling bulls with and without the double muscling gene (mh/mh = 24, mh/+ = 26, +/+ = 25) were measured to examine if this gene influences the pattern of PUFA deposition in different adipose tissues. Fatty acid compositions of muscle tissue (longissimus thoracis) and intermuscular and subcutaneous adipose tissues were determined by gas chromatography. The composition of intramuscular fat was unique compared to the other two adipose tissues which were similar in composition. In general, n-6 and n-3 fatty acid...
The first observation of milkability of the sheep breeds Tsigai, Improved Valachian and their crosses with Lacaune

Czech J. Anim. Sci., 2008, 53(12):528-536 | DOI: 10.17221/369-CJAS
The aim of this study was to evaluate the milkability of two purebred breeds Tsigai (TS, n = 14) and Improved Valachian (IV, n = 15), their crosses with Lacaune 50% TS × 50% LC (n = 13), 50% IV × 50% LC (n = 9) and purebred Lacaune (LC, n = 19). The measurements of the milk flow were performed on day 90 ± 10 of lactation during evening machine milking. The recording of milk flow was carried out by the equipment for graduated electronic recording of milk level in a jar in one-second intervals. The milk flow curves were classified into four types: 1 peak (1P), 2 peaks (2P), plateau I (maximal milk flow over 0.4...

In this study, a novel missense (NM_174579:c.1201C>T) mutation in exon 6 at the bovine POU1F1 locus is reported, which results in p.S284F, namely, Ser (TCT) > Phe (TTT) at position 284 of the mature protein. A DdeI PCR-RFLP was used to determine the genotypes. The polymorphism was studied in eight Chinese cattle breeds (Nanyang, n = 251; Qinchuan, 149; Jiaxian Red, 144; Chinese Holstein, 61; Luxi, 57; Angus, 49; Jinnan, 60; Guyuan, 192). The frequencies of the POU1F1 T allele in the analyzed populations ranged from 0.010 to 0.053. The relationships between the DdeI polymorphism and growth traits and body sizes...

The construction of the Římov Reservoir on the Malše River in 1978 significantly influenced the fish assemblage within the river, above the reservoir. Fish species that had successfully colonised the reservoir after impoundment expanded to the inflowing river. The changes in the riverine fish assemblage up to the first impassable weir (4 km upstream) reflected the development of the reservoir assemblage after an impoundment boom of pike (Esox lucius), then the perch (Perca fluviatilis) dominated phase and later the final cyprinid-dominated phase. The changes in the fish fauna over the period 1978-2002 were significant (χ2,...
