A study was conducted to assess production performance, feed efficiency and their correlation in lactating Kankrej cows at organized farm. The variables such as average dry matter intake, milk yield, milk composition and feed efficiency were evaluated in 49 lactating Kankrej cows over a period of 30 days. The mean dry matter intake was 9.71±0.08 kg/d. The average milk yield and energy corrected milk were 12.45±0.35 kg/d and 14.27±0.47 kg/d, respectively. Feed efficiency was 1.48±0.05 in Kankrej cows, and it was significantly affected by average milk yield and energy corrected milk. The average milk yield and energy corrected milk were highly correlated with feed efficiency. Pearson’s square correlation coefficient was 0.96 between feed efficiency and energy corrected milk.

Abstract The objective of this study was to evaluate the effects of different energy sources on performance, and carcass characteristics in hair lambs finished in feedlots. Twenty-eight hair lambs with an initial body weight (BW) 20.8 ± 3.01, were randomly assigned to one of four dietary treatments included with seven lambs per treatment. The dietary treatments included an energy source included at 18% Dry matter: S. spectabilis flour (SF), palm kernel (PK), corn bran (CB) and rice bran (RB) in a diet based in corn silage, ground corn, soybean meal formulated to 13.0% PC and 2.6 Mcal/Kg of DM. The feeding trial was performed for 13 weeks. Water was allowed ad libitum. Animals were slaughtered after the feeding trial, and the carcasses were kept at 4°C for 24 h under Colombian standard guidelines. Data were analyzed by using the ANOVA procedure, SAS version 9.1 to perform a randomized complete experiment with four diets. For each studied variable, the mean and standard error of the mean (SEM) were calculated and differences between means were evaluated Using Tukey′s Test (P ≤ 0.05). Final body weight, hot carcass weight, cold carcass weight, hot dressing carcass (%), and cold dressing weight (%) were not different between the four treatments (P > 0.05). Dry matter intake was superior to the S. spectabilis flour (P < 0,001). Feed efficiency was higher in the CB and RB treatments (P < 0,05). These results indicate that the inclusion of S. spectabilis and palm kernel could improve the dry matter intake and corn bran and rice bran the feed efficiency without effects on carcass characteristics

Block Experiment

ABSTRACTA randomized block experiment was used to assess the effects of wilting of herbage prior to ensiling. Three silages, each a composite of three harvests taken over the season, were prepared by ensiling herbage as unwilted, medium-wilted or high-wilted material with mean dry-matter contents in the resulting silages of 192, 254 and 455g/kg respectively. The silages were ensiled in bunker silos using the same harvesting machinery and with formic acid applied at the rate of 2 81/t of herbage. The silages were offered to 81 January- and February-calving cows from the 8th day post partum until going to pasture on 27 April, with a mean period on treatmen t of 92 days. In addition, all animals received a fixed concentrate allowance of 7·6 kg/day. Wilting increased silage dry-matter intake, the mean intakes being 9·2, 9·4 and 10·0kg/day for the unwilted, medium-wilted and high-wilted material respectively, but resulted in a significant depression in milk yield, with the yields obtained during the final 14 days on treatment being 23·6, 21 -8 and 21·5kg/day respectively. Milk composition, live weight, body condition, total ration digestibility and nitrogen-balance data are also presented.

Plasma Amino Acids

The objectives of this study were to examine the effect of supplying post-ruminal L-glutamine in mid-lactation Holstein dairy cows on plasma amino acid profile, dry matter intake, milk yield and milk composition. The experiment was designed as a 4 × 4 Latin square with four 2-wk periods. Cows were continuously infused post-ruminally with graded levels of L-glutamine (L-Gln) for 5 consecutive days during the second week of each period. During the last 24 h of the infusion, blood plasma was collected every 6 h for the determination of plasma amino acid concentrations. Plasma Gln concentration increased (P < 0.05) with increasing L-Gln daily infusions. Infusion of 0, 100, 200, and 300 g d–1 resulted in blood plasma Gln concentrations of 289.5, 299.2, 356.4 and 386.2 mmol L–1, respectively. The level of Gln infusion also resulted in a decrease in the blood plasma concentration of phenylalanine, but the concentrations of all other amino acids were not affected. The administration of Gln did not affect dry matter intake, milk yield and milk composition. Key words: Post-ruminal, L-glutamine, plasma amino acids, milk constituents

Effect Of Feeding

Feeding the dairy cow during the transition phase (dry to lactating) has been found to effect subsequent feed intake and milk yield (Moorby et al., 1996; Olsson et al., 1998). The aim of this study was to compare the effect of feeding a liquid feed during the prepartum period on; feed intake, milk yield, milk composition, live weight loss and blood metabolite levels.

The research was carried out to determine the effects of cumin seeds in food diets of Anatolian water buffaloes (AWB) in shelter about gas concentration, milk yield and composition. The animal material of the experiment was conducted with 27 buffaloes at Karaoglan Village located in Mustafakemalpasa, Bursa. Three different buffalo shelters (E1, E2 and E3) and three different diets (S1; S2; and S3) (0, 10 and 30 g grounding cumin seeds (GCS) kg-1) in 3x3 a replicated Latin square design was used with nine replicates of one buffalo each. Periods lasted 21 days, in which the first two weeks were preliminary for adaptation and data for statistical analysis collected in week 3. In conclusion, It has been determined that 30 g cumin supplementation to AWB diets (S3; one kg of diet) significantly increased total dry matter intake and milk yield of AWB (P<0:01). Meanwhile; there were no significant effects of diets containing cuminun seeds in milk composition, somatic cell count (SCC) and shelter about gas concentrations (CH4, NH3 and CO2).

According on the fat source included in the diets for goats, the milk production can be increased and milk fatty acid composition can be improved. This study was conducted to evaluate the inclusion of protected fat (CSFA - calcium salts of fatty acids) in the diets of lactating Saanen goats on milk production and composition. Five Saanen goats (63.23 ± 9.08 kg body weight and 105 ± 3 days of lactation) were distributed in a Latin square design (5 × 5) with five diets: control (without the addition of CSFA) and the other diets with: 6.25, 12.50, 18.75 and 25.0 g CSFA per kg dry matter (g/kg DM), respectively. Dry matter intake (DMI) and milk production (MP) were evaluated. Milk samples were collected to determine milk composition and fatty acid profile. Feed efficiency (FE) was estimated. The supplementation of CSFA up to 25 g/kg DM did not influence the DMI, MP and FE. Milk components production (g/d) was not influenced by the inclusion CSFA in the diet; however, there was a linear reduction of 0.87 g protein per kg of milk for each 1% CSFA included in the diet. The concentration of linolenic acid (18:3n-3) in milk was improved with a maximum point of 24 g of CSFA per kg DM. CSFA can be included in the diets of lactating Saanen goats up to 25 g/kg DM with no interference on DMI and MP.

Phenotypes related to feed efficiency were predicted from records easily acquired by breeding organizations. A total of 461,036 and 354,148 records were collected from the first and second parity Holstein cows. Equations were applied to the milk mid-infrared spectra to predict the main milk components and coupled with animal characteristics to predict the body weight (pBW). Dry matter intake (pDMI) was predicted from pBW using the National Research Council (NRC) equation. The consumption index (pIC) was estimated from pDMI and fat, and protein corrected milk. All traits were modeled using single trait test-day models. Descriptive statistics were within the expected range. Milk yield, pDMI, and pBW were phenotypically positively related (r ranged from 0.08 to 0.64). As expected, pIC was phenotypically negatively correlated with milk yield (−0.77 and −0.80 for the first and second lactation) and slightly positively correlated with pBW (0.16 and 0.07 for the first and second lactation). Later, parity cows seemed to have a better feed efficiency as they had a lower pIC. Although the prediction accuracy was moderate, the observed behaviors of studied traits by year, stage of lactation, and parity were in agreement with the literature. Moreover, as a genetic component was highlighted (heritability around 0.18), it would be interesting to realize a genetic evaluation of these traits and compare the obtained breeding values with the ones estimated for sires having daughters with reference feed efficiency records.

ABSTRACTData for individually recorded silage dry-matter intake (SDMI), concentrate dry-matter intake (CDMI), live weight, milk yield and milk composition of lactating dairy cows offered silage ad libitum and concentrates on a flat-rate basis, together with data for silage composition from experiments conducted at four sites, were used to obtain simple and multiple regressions of SDMI on other variables.Simple regressions showed that the most important variables affecting SDMI were, in order of importance: silage ammonia nitrogen, fat yield, CDMI, silage digestible organic matter concentration (DOMD) and live weight. The best multiple regression for the mean SDMI over weeks 4 to 13 of lactation accounted for proportionately 0·649 of the variation. Examination of week by week data for weeks 3 to 20 of lactation showed that two models for early and mid lactation were required to give a reasonable pattern of residual variances. These models accounted for 0·627 and 0·581 of the variation respectively. It was necessary to fit time effects explicitly in early lactation. Live weight was best represented by fitting post-calving live weight and deviations from post-calving live weight separately. A number of models requiring fewer input variables were also obtained to allow for use in situations where the full range of measurements is not made.The new models were tested using independent data from three sites. They performed better than a number of previously published models but the best model still gave a prediction error of proportionately 0·17 about the mean actual silage intake in early lactation and 015 in late lactation.The results suggest that there is little to be gained from further refinement of the functional form of the models and that the construction of a number of models for specific food and management situations is preferable to the use of global models.
