Productive Traits

The aim of this study was to investigate the effect of using dried stoned olive pomace (DSOP) as a feed supplement for dairy cattle on productive performances and milk quality traits. Control (C) and experimental (E) diets were formulated and offered to lactating Italian Holstein cows placed into two groups (five cows each) that were homogenous for liveweight (630.8 vs 667.2 kg) and for the main physiological and productive traits. The E group received 1.181 kg on dry matter (DM) basis of DSOP as a part of the concentrates pool. The C group was fed an isoenergetic (0.90 milk forage units (FU) /kg DM) and isoprotein (161.4 g/kg DM crude protein (CP)) ration but without the inclusion of DSOP. DM intake was 21 kg/day and the experiment lasted 40 days. There were no significant effects of diet on cattle performance (liveweight and body condition score), milk yield and quality (fat, protein, lactose, urea) or coagulation traits (pH, r, K20, A30). The results showed that the inclusion of DSOP (5.61% of the total diet on DM basis) is not related to detrimental effects and could represent a valid supplement for dairy cattle.

Mature Size

Taylor (1980) indicated the importance of mature size in the description of animals and its usefulness for standardising growth parameters. The mature size and body composition of the Gallego breed, a small meat-producing type first described by Mason (1967), have never been estimated under defined management conditions. Therefore, using the scaling rules and results of Thonney, Taylor, Murray and McClelland (1987) as a guide, a study was made to determine whether the reputation of Gallego lambs for producing lean carcases was borne out in the composition of mature animals.Twenty-one ewes (mean liveweight, LW, 32.7, sd 5.4 kg) and eight rams (LW 47.6, sd 8.6 kg) were selected as cast animals on the basis of age ( >4 years), body condition score (BCS, >1.75), health and teeth status and group-fed on concentrate (180 g crude protein/ kg dry-matter) and hay ad libitum. LW was measured fortnightly. When all animals had a LW and BCS which were stable for 2 months, 3 subgroups were slaughtered monthly. Weights of wool, body organs and hot carcase (HC) were recorded. Dissection of the cold carcase (CC) into commercial joints (Cabrero Poveda, 1984) and total lean, bone and fat.

Nutritional research on commercial farms is difficult to carry out due to the problems associated with measuring individual animal dry matter intake (DMI). This research was aimed at developing a satisfactory method of estimating DMI from routine farm records, supplemented by cow body condition score and height at withers of the cow.

Obesity is a common problem in cats. In the experimental cat family of the institute of animal nutrition besides a “normal” lean phenotype, cats with predisposition to an overweight phenotype are present. To investigate energy requirements and food intake behaviour of intact male cats of different phenotypes, six “normal” lean cats (GL) and six cats disposed to overweight (GO) were used. At the beginning of the experiment, all cats had an ideal body condition score of 5. To reach this the GO cats had to pass a weight-loss program. Energy requirements of the cats were determined using respiration chambers, whereas the amount and frequency of food intake was measured with a feeding station recording the data automatically. Energy requirement at weight constancy of the GO cats was even on fat-free mass (FFM) significantly (P=0.02) lower (162.6 kJ/kg FFM/d) than that of the “normal” lean cats (246 kJ/kg FFM/d). The GO cats also showed a higher food intake34.5±1.5 g dry matter/kg body weight0.67compared to the GL cats (24.0±2.1 g dry matter/kg body weight0.67)(P=0.001). In conclusion quantifiable differences in food intake and behaviour in cats predisposed to overweight compared to “normal” lean cats were found.

Yield And Quality

Maize is the very important silage source in the world. Timely harvesting ensure high maize forage yield and quality. Therefore, the study focused on the effects of four harvesting times (starting at the 12 August every 7 days) on yield and qualitative parameters of forage green mass of maize hybrid ZP 677. The experiment was set in Vojvodina Province, Serbia, during the 2013 and 2014 growing seasons. Plant height, stem diameter, number of leaves per plant, ear percentage, forage yield, dry matter content and crude protein content were higher, while stem percentage was lower in 2014 with favorable climatic condition. Forage yield, crude protein content, ADF and NDF decreased, while dry matter content significantly increased with delay in harvesting. The maize hybrid should be harvested when the milk line is three-quarter of the way down the grain that is in the third decade of August.

An experiment was conducted to evaluate the effect of growth, biomas yieds and nutritive value of Lablab purpureus, Centrosema pubescens and Mucuna pruriens under rain fed condition in Yola, Adamawa State, Nigeria. The field experiment was laid in a randomized complete block design with the plot divided into three main plots and replicated three times measuring 5x5m with inter and intra row spacings of 0.5m. The five harvesting stages are 6, 8, 10, 12 and 14 weeks, respectively. The growth in height increases with stage of growth and declined with reduction in rainfall. Higher growth were recorded in T3 (3.8 -354.8cm) followed by T2 (2.96-260.20cm) and then T1 (1.50-213.00cm) and the results were presented graphically. The result of the chemical composition of all the legumes showed that the crude protein decreases with stage of growth from weeks 6 -14 (14.40, 12.26, 10.65-10.08, 6.79, 6.49) and ADF and NDF (25.20, 32.15, 27.35-42.13, 40.33, 36.50 and 32.20, 54.45, 47.00- 51.24, 63.53, 66.33), respectively. The biomass yields were significantly different (P<0.05) for all the legumes at different harvesting stages T1 (2744.53-3186.93), T2 (2696.47- 3006.70) and T3 (2843.73-3147.63). It is therefore concluded that legumes could best be harvested between weeks 10 and 12 when the yield and quality are at levels to sustain the animals both for maintenance and production.

Daily Milk Yield

The selection of dairy cattle for high milk production is thought to be linked to increased problems with fertility. Most research has concentrated on the influence of actual yields rather than the effect of genetic merit on fertility. It has also been reported that by maintaining a high level of herd management the reproductive efficiency problems associated with high milk production can be removed (Nebel and Gilliard, 1993). The current work estimated the influence of genetic merit (defined as PIN95), 90-day daily milk yield, deviation from herd mean 305-day milk yield and body condition score on fertility, in an attempt to assess whether actual yield has more effect than potential yield as indicated by genetic merit.

Abstract The objective of this study was to evaluate the milk production, body weight, and body condition score (BCS) of ewes fed with different energy levels. Seventy-one ewes were used and distributed in three treatments according to the metabolizable energy (ME, Mcal/kg) levels in the diet: CTL = according to the NRC (2007) recommendation for each stage (gestation and lactation); PLUS = CTL plus 10% of ME per kilogram of dry matter; LESS = CTL less 10% ME per kilogram of dry matter. Body weight and body condition score were evaluated a week before the expected date of parturition, a week after giving birth, and at weaning (60 days). Dairy production was evaluated at 20, 30, 40, 50 and 60 days after giving birth by the indirect method of the two weighing. The experimental design was analyzed as randomized complete blocks. There were no differences on milk production during almost all the lactation curve. Only on day 50 (P = 0.051), CTL was still at peak, while LESS and PLUS had already decreased their production. However, at 60 days, all treatments were already with low production, justifying weaning in this period. Results of weight and BCS showed a significant difference in all periods evaluates. Ewes in the PLUS diet had greater BW and BCS. The BCS before giving birth is expected to be over 3.5 and treatment LESS was the only one that did not achieve this score (2.66, 3.37, 3.83 for LESS, CTL, and PLUS, respectively). At weaning, ewes fed PLUS and CTL had BCS of 3.51 and 2.92, respectively, but treatment LESS had only 1.82. That is prejudicial for the next mating seasonal and this animal. We concluded that LESS diet interfered with the body reserves of sheep.
