Cattle Management

A survey was conducted to document general characteristics of beef cattle management and identify producer concerns in Manitoba. The survey was divided into five sections: (i) characterization of farm operation, (ii) winter management, (iii) forage and pasture management, (iv) reproductive management and (v) factors limiting profitability and the use of non-traditional management tools. The surveyprovided base information for measuring change in the industry and identified cost of production, pasture, and reproduction as the top three factors that producers consider limiting the profitability of beef operations in Manitoba. Key words: Beef cattle, forage, pasture, reproduction, nutrition, survey

Milk yield and composition from three distinct milkings (spring, August, and fall) were evaluated on first-cross and backcross cows maintained under two contrasting environments. The dam crosses at Brandon (semi-intensive cultivated pasture management) were HA, SN, CN, ACA, CCA, ASA, SSA, HCH, CCH, HSH, SSH, NCN, CCN, NSN, and SSN with H = Hereford, A = Angus, N = Shorthorn, C = Charolais, S = Simmental and a SSA cross was 3/4 Simmental-1/4 Angus. At Manyberries (semi-arid and short grass rangeland) the dam crosses were HA, SN, ASA, SSA, HSH SSH, NSN, and SSN. All cows were bred to Limousin bulls and milkings took place from 1981 to 1985, inclusive. Definitive differences among the backcrosses and between the backcrosses and the F1 crosses were not present. Possible genotupe × environment interactins were observed for milk yield and composition. Milk yield and composition were affected by age of cow and influenced cow and calf weight changes. Key words: Beef cattle, crossbreeding, backcrosses, milk yield, milk composition

Atom Source

Reaction of McConville's chelating amido titanium complex [(Ar)NCH2CH2CH2N(Ar)]Ti(CH3)2 (Ar = 2,6-i-Pr2C6H3) with either elemental Se or the tellurium atom source Te=PBu3 resulted in the formation of bis-µ-chalcogenido dimers [(Ar)NCH2CH2CH2N(Ar)]2Ti(µ-E)2 (E = Se, 2; Te, 3) with concommitant loss of EMe2. The dimers 2 and 3 were characterized spectroscopically and via X-ray crystallography. The two compounds are isostructural in the solid state. The tellurido dimer 3 may also be synthesized by reduction of the diamido dichloride [(Ar)NCH2CH2CH2N(Ar)]2TiCl2 with Na–Hg amalgam followed by treatment with Te=PBu3. This dimer is unreactive toward further Te=PBu3 or stannanes such as HSnBu3. Unlike decamethyltitanocene derivatives, the diamido complex is not an effective catalyst precursor for the heterohydrodecoupling of Te=PBu3 and HSnBu3.Key words: diamido titanium complexes, selenides, tellurides.

Physical Output

While low-cost technology can be applied within beef cattle systems to improve economic output and decrease economic risk, methodologies to increase adoption by farmers deserve attention. Here we report 4 case studies where low-cost, high-impact technology was applied on commercial farms in an endeavor to demonstrate increased physical output in what we describe as 'Producer Demonstration Sites'. Forage allowance (FA) affects forage growth, forage intake by animals and energy partitioning to maintenance or production. We decided to demonstrate the benefits to production from controlling forage allowance at specific recommended levels. While we focused on FA, other management tools, e.g. suckling restriction and energy supplementation of cows prior to breeding, were tested in different contexts and time periods to improve the critical responses mentioned. While increases in production from 3 of the farms were demonstrated, only 2 of the farmers showed interest in implementing the strategies on their farms subsequently. We conclude that control of forage allowance improved energy intake. For this approach to be successful and increase adoption, it is important to involve the farmers in discussions regarding the proposed changes from the outset as well as the monitoring of progress during the demonstration.

<div class="WordSection1"><p><em>The research was conducted to know the number of the productive female beef cattle slaughtering at abattoir in DIY. All of the beef cattle which slaughtered along a month were used in this research. The result showed that the number of productive beef cattle slaughtered  up to 2 years old were 28.98%; 2 – 5 years old were 69.55%; more than 5 years old were 1.44%. The female beef cattle slaughtered were 54.58% and the male beef cattle slaughtered were 32.36%. The non productive beef cattle slaughtered were 13.04% including 5.79% male and 7.24% female. The Peranakan Ongole (PO) breed slaughtered was 60.36% (125 heads), Brahman Cross 16.42% (34 heads), Simmental 15.94% (33 heads), Brangus 2.42% (5 heads), Limousine 4.35% (9 heads) and PFH 0.48% (1 heads). The percentage of productive beef cattle slaughtering were 86.95% with female beef productive were 64.25% and the PO breed at 2 – 5 years old were the most slaughtered. It could be concluded that the productive female beef cattle slaughtering at abattoir in DIY was quite high, which may influence the breed resources of beef cattle.</em></p><p><em> </em></p><p><em>Key words : Productive beef cattle, slaughtering, abattoir, Yogyakarta</em></p></div><em><br clear="all" /> </em>
