“…The meat and milk produced in Mexico does not cover the national demand; therefore, importation is needed (SAGARPA 2006). In Southeastern Mexico, weaning calves is the main livestock activity; therefore, fertility, maternal ability and productive life of cows, as well as production and growth of the calves are characteristics of economic importance (Delgado et al 2004;Magaña and Segura-Correa 2006). However, in the Mexican tropics, the production of beef cattle is limited mainly by the poor reproductive and productive performance of animals, with <60% annual calving rate and calves weighing <160 kg at weaning, at 8 months of age (Magaña and Segura-Correa 2001;Delgado et al 2004).…”

The effect of age at first calving (AFC) and breed type (BG) on cow length of productive life in the herd (LPL) and cumulative kilograms of calves weaned per cow (KWC) was studied. Data on 313 Brahman, 183 Nellore, and 269 crossbred cows (undefined crosses of European × Zebu cattle) born from 1986 to 2002 were used. Three hundred and ninety-one out of the 765 cows had non-censored data. LPL curves by BG and AFC (<2.5, 2.5 to <3, 3 to <3.5, and ≥ 3.5 years of age) were obtained using life table procedures. The magnitude of the effect of AFC and BG on LPL was determined using Cox proportional hazard regression procedures. KWC data (n=359) were analyzed by a linear model that included the effects of period of birth of the cow (in years), BG, and AFC. There was no difference in the survival curves between BG (p>0.05), but there was for the hazard ratio of culling (p<0.05). Brahman and Nellore cows produced more kilograms of calves (p<0.05) than crossbred cows. AFC influenced LPL (p=0.014) and KWC (p=0.012). Cows with AFC <3 years of age stayed longer in the herd and weaned more KWC than those with a higher AFC (p<0.05).

“…Notwithstanding mineral deficiencies (Lebdosoekojo et al 1980;Depablos et al 2009), low LWs and energy and protein deficit intakes , and the effect of lactation and suckling constitute the major constraints to efficient reproductive performance (Osorio-Arce et al 2002;Delgado et al 2004;Montiel and Ahuja 2005;Schatz and Heamden 2017). These factors probably explain the long inter-calving periods reported in Table 5.…”

A substantial proportion of beef production in Colombia originates in its extensiveEastern Plains. However, in this scenario and in a global context, demand for cattleproduction increasingly requests that it satisfies social and environmental expectationsin addition to being economically efficient. A dataset containing five-year long recordsof cow-calf production systems collected at Carimagua Research Centre located in theMeta Department was retrospectively interrogated to understand the liveweight (LW)-derived flux matrix dynamics of methane (CH4) emissions. Estimated total CH4 (kg)emissions during the gestation period, were similar between conventional weaned (CW;37.86 ± 0.506 kg) and early weaned (EW; 37.47 ± 0.476 kg) cows. However, averagedover two lactations, total CH4 emissions were larger (p < 0.0001) in CW cows (38.67± 0.456 kg) than in their EW (14.40 ± 0.435 kg) counterparts. Total gas emissionsfrom birth to comparable commercial yearlings age were higher (p < 0.0001) for CW(43.11 ± 0.498 kg) calves than for EW (40.27 ± 0.472 kg) calves. It was concluded thatmid and long-term pastoral datasets and new concerns are well suited to understanddifferent contexts and adaptations to the contemporary weather conditions. Nevertheless,conventional farming systems will be less environmentally vulnerable if EWmanagement practices involve the strategic and temporal use of improved pastures. Theroles of veterinary medicine and animal sciences are briefly discussed in the context ofunprecedented climate variability to provide a guide to the uncertain future.

A research work was undertaken to evaluate the feeding effects of di-calcium phosphate (DCP) on calcium balance and body condition score of dairy cows fed Napier grass. The trial was conducted in the village Alokdiar of Shajadpur upazilla under Sirajgonj district. Twenty crossbred lactating dairy cows of 320 ±15.5 kg live weight were used for the trial. Animals were equally and randomly allocated into four groups, T0 (Napier+concentrate), T1 (Napier+concentrate+100g DCP), T2 (Napier+concentrate+150g DCP) and T3 (Napier+concentrate+200g DCP). Total DMI did not differ significantly (p>0.05) among the groups but highly significant differences (p<0.01) were found in Ca intake. Ca balance; and Ca in feces, Ca in urine, Ca in milk and total Ca excretion differed significantly (p<0.05). No significant difference (p>0.05) was found in DM in feces (%), DM in feces (kg/d) and milk production (L) among the treatment groups except urine excretion. There was a linear increase of body condition score (BCS) with DCP (T1, T2 and T3), but BCS was linearly declined in non DCP diet (T0). Diets with 150g DCP may be suggested for optimizing Calcium balance and body condition score of dairy cows fed Napier grasses.DOI: http://dx.doi.org/10.3329/bjas.v43i3.21648 Bang. J. Anim.
