The aim of this study was to determine the fatty acid profile in 4 types of fat deposits in Polish Holstein-Friesian (PHF) and Limousine × Polish Holstein-Friesian (LM × PHF) bulls. The experimental materials included samples of intramuscular, intermuscular, subcutaneous, and internal fat collected from the carcasses of 28 PHF bulls and 26 LM × PHF bulls. Determined fatty acids (FAs) were divided into saturated (SFAs) and unsaturated (UFAs) FAs, including monounsaturated (MUFAs) and polyunsaturated (PUFAs) FAs. The UFA/SFA, MUFA/SFA, PUFA/SFA, and PUFA n-6/PUFA n-3 ratios were calculated. Internal fat was characterized by the highest SFA concentrations, and subcutaneous fat …
Insertion/Deletion Polymorphism Of The Sterol Regulatory Element-Binding Protein 1 Gene In Different Cattle Breeds, Witold Stanislaw Proskura
Insertion/Deletion Polymorphism Of The Sterol Regulatory Element-Binding Protein 1 Gene In Different Cattle Breeds, Witold Stanislaw Proskura
Turkish Journal of Veterinary & Animal Sciences
In the present study, an 84-bp insertion/deletion polymorphism of the sterol regulatory element-binding protein 1 (SREBP1) gene was investigated. The analysis included 6 Polish cattle herds consisting of beef (Limousin, Angus, Charolais), dairy (Holstein-Friesian, Jersey) and dual-purpose (Montbeliard) breeds. The polymorphism was found only in Limousin and Montbeliard animals, in which both the short (S)- and long (L)-type alleles occurred. The genotype distribution in Montbeliard cattle was as follows: 0.038, 0.406, and 0.556 for SS, LS, and LL, respectively. To the author's knowledge, this study was the first to investigate the above-mentioned polymorphic site in the Montbeliard and Jersey cattle …

Chitosan (CH) has been shown to be a promising natural antimicrobial agent. This study examined the effects on rumen metabolism when providing diets containing high forage (HFD), low forage (LFD), and maize silage (MSD) to a 24-h batch culture in which the diets were not supplemented (control) or were supplemented with CH (100 mg/L), sunflower oil (SF, 35.0 g/kg dry matter), rapeseed oil (RP, 35.0 g/kg dry matter), or SF and RF with chitosan combinations (SFCH and RPCH). Dry matter digestibility in the batch culture was influenced by CH and was decreased in HFD compared with the control (P < 0.01). Decreasing total number of protozoa and the number of Entodinium spp. was evident, especially in LFD and MSD, with all additives. RPCH had a predominantly adverse effect on Dasytricha ruminantium in MSD. Interactions of the diets × additives in the majority of rumen ciliate populations were detected. The concentrations of trans-vaccenic acid and conjugated linoleic acid (c9, t11-CLA) were unchanged by chitosan. However, the combination of SF and RF with chitosan (SFCH and RPCH) positively affected fatty acid profiles, which might be related to differences in diets, SF or RP composition, and different microbial activity in the batch cultures.

To study the effects of royal jelly (RJ) on performance and fatty acid profiles, 168 unsexed 8-day-old quails (Coturnix coturnix japonica) were assigned to 4 treatment groups. Groups were arranged as follows: control (LSD; 160 cm2/quail and no supplementation), high stocking density (HSD; 80 cm2/quail and no supplementation), HSD-RJ 250 [80 cm2/quail and 250 mg/kg body weight (BW) RJ given orally], and HSD-RJ 500 (80 cm2/quail and 500 mg/kg BW RJ given orally). Body weight gain decreased significantly in the HSD group at day 42 (P < 0.01). Feed intake (FI) and feed conversion rate (FCR) were also significantly affected in the HSD group (P < 0.01). FI and FCR were improved by both doses of RJ. Both RJ doses increased total polyunsaturated fatty acid ratios in the breast, kidney (P < 0.001), leg, and liver (P < 0.05). Total saturated fatty acid ratios in leg (P < 0.01) and kidney (P < 0.05) tissues increased in the HSD group but decreased in the livers of HSD-RJ 250 group (P < 0.05). In conclusion, RJ supplementation improved performance parameters and unsaturated fatty acid ratios in the examined quail tissues.

The aim of this research was to study the effects of seasons (rainy and dry) on the composition of the fatty acids (FAs) in milk of Creole goats in a semiintensive production system. Milk sampling was carried out in the dry season (June) and just after the rainy season (November) in an arid region of Baja California Sur, Mexico. The goat diet was composed of native species it grazed on in the rangeland, as well as hayed forages with some supplements containing approximately equal amounts of sorghum and maize. The results for different types of FAs in goat milk showed …
