“…For this reason, determining an optimal grass cutting moment is important to obtain grass with the highest protein content [45]. P in animal feed is directly related to the productive and reproductive efciency of cows [46,47]. In soils rich in P, grasses will have a high concentration of this mineral, but if P is not usable, the grass will be defcient in this mineral [48], generating the need for mineral supplementation.…”

Livestock production in the Peruvian tropics is mainly based on grazing and cutting grasses, which have variable productive and nutritional characteristics according to the variety of grasses, agronomic management, and climatic conditions. The objective of this research was to compare the agronomic behaviour and chemical composition of three varieties of Pennisetum sp (Pennisetum purpureum Schum cv. Cameroon or Cameroon grass, Pennisetum sp. or Maralfalfa, and Pennisetum purpureum × Pennisetum typhoides or King grass). The experiment was carried out at the Estación Experimental Agraria “Campo Verde,” Ucayali, Peru, under a randomized complete block design (RCBD) with a 3 (Pennisetum sp. variety) × 3 (cutting age) factorial arrangement and 4 replicates each. Thirty-six subplots were installed, and treatments were randomly assigned, using vegetative seed with three buds each. Measurements of agronomic behaviour and chemical analysis were carried out in the 8th, 12th, and 16th week. The data were subjected to ANOVA and multiple comparisons with the Duncan and Kruskal–Wallis tests ( p < 0.05) and correlations using Pearson coefficients ( p < 0.05). The agronomic behaviour did not vary between Pennisetum sp. varieties, but according to cutting age, Cameroon grass produced greater plant height, biomass, dry matter, and Mg content at the 8th week. The highest concentrations of N (2.38 ± 0.11%), P (0.18 ± 0.01%), and Ca (0.70 ± 0.03%) were recorded at the 8th week, Zn (27.33 ± 1.91 mg/kg) at the 12th week, and Mg (0.26 ± 0.02%) at the 16th week. A negative correlation was found between biomass and the stem-leaf ratio at the 12th week because the first leaves of plants died, but the stems increased in size. It is concluded that, at an early cutting age in varieties of Pennisetum sp., lower biomass and dry matter result, but higher content of N, P, Ca, and Fe; and at a late cutting age, it shows greater biomass, dry matter, Cu, and Mg content.

“…Moreover, some breeders' cross local cattle with Limousine semen or Simmental, Brahman to get a breed of cattle that have a better production performance than the local cattle and to get the proceeds of sale the cattle is high. In fact, the maintenance of crossbred also has constraints in reproduction for low heifers compared to local cows (Malau-Aduli et al, 2021).…”

Background: The genetic diversity information of local cattle and crossbred in South Sulawesi, Indonesia is essential for the establishment of conservation and breeding strategies. This research targeted to evaluate the phylogenetic relationship and genetic diversity of local and crossbred (CB) cattle. Methods: The present research organized at the Animal Laboratory, Professor Nidom Foundation, Surabaya, Indonesia from February to October 2021. The genome was isolated from 20 whole blood samples from seven purebreed belongs to Singosari National Artificial Insemination Center Malang, Indonesia, four crossbred in Gowa and nine crossbred in Sidrap, South Sulawesi, Indonesia. Partial sequences of mtDNA cytochrome oxidase subunit I (COI) gene were amplified employing the polymerase chain reaction technique. Result: This study revealed that a lot of single nucleotide polymorphism (SNP) found in local cattle (Bali and Peranakan Ongole) and CB cattle in Gowa and Sidrap indicated various genetic diversity can be used as a marker candidate and potential to be developed into future research knowing the correlation of the SNP with the growth rate of CB. Thus, this information will be helpful for further strategy in breeding development program.

“…Consumers demand healthier, safer, and more consistent beef of high eating quality [ 1 , 2 ]. Currently, the Australian and global beef industry, supported by research bodies, has shifted its attention to finding ways of producing meat of consistent eating quality and health-promoting ≥C20 omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) that play essential roles in human disease prevention [ 3 , 4 ]. Intramuscular fat content (IMF), fat melting point (FMP), and ≥C20 n-3 LC-PUFA composition are associated with consumer satisfaction and key eating quality attributes in the Australian, American, and Japanese beef industries because of their associations with taste, smell, texture, tenderness, flavor, and juiciness [ 1 , 5 , 6 , 7 ].…”

“…The composition of n-3 LC-PUFA in the muscle tissue is influenced by animal diet, age, production system, and genetics [ 3 , 11 ]. Several studies utilized dietary means to manipulate fat deposition and fatty acid composition [ 12 , 13 , 14 , 15 , 16 ].…”

This study used targeted sequencing aimed at identifying single nucleotide polymorphisms (SNP) in lipogenic genes and their associations with health-beneficial omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA), intramuscular fat (IMF), and fat melting point (FMP) of the M. longissimus dorsi muscle in Australian pasture-based Bowen Genetics Forest Pastoral Angus, Hereford, and Wagyu cattle. It was hypothesized that SNP encoding for the fatty acid-binding protein 4 (FABP4), stearoyl-CoA desaturase (SCD), and fatty acid synthase (FASN) genes will be significantly associated with health-beneficial n-3 LC-PUFA and the meat eating quality traits of IMF and FMP in an Australian pasture-based beef production system. Two SNP mutations, g.21267406 T>C and g.21271264 C>A, in the SCD gene were significantly (p < 0.05) associated with IMF, FMP, oleic acid (18:1n-9), linoleic acid (LA) 18:2n-6, alpha-linolenic acid (ALA) 18:3n-3, eicosapentaenoic acid (EPA) 20:5n-3, docosahexaenoic acid (DHA) 22:6-n-3, and docosapentaenoic acid (DPA) 22:5n-3. Significant positive correlations (p < 0.05) between FASN SNP g. 50787138 A>G and FMP, 18:1n-9, ALA, EPA, DHA, DPA, and total n-3 LC-PUFA were also detected. An SNP (g.44678794 G>A) in the FABP4 gene was associated with FMP. These results provide significant insights into the contributions of lipogenic genes to intramuscular fat deposition and the biosynthesis of health-beneficial n-3 LC-PUFA. The findings also unravel the potential use of lipogenic gene polymorphisms in marker-assisted selection to improve the content of health-promoting n-3 LC-PUFA and meat eating quality traits in Australian pasture-based Bowen Genetics Forest Pastoral Angus, Hereford, and Wagyu beef cattle.
