Abstract Hyperprolific sows rear more piglets than they have teats, and to accommodate this, milk replacers are often offered as a supplement. Milk replacers are based on bovine milk, yet components of vegetable origin are often added. This may reduce growth, but could also accelerate maturational changes. Therefore, we investigated the effect of feeding piglets a milk replacer with gradually increasing levels of wheat flour on growth, gut enzyme activity and immune function compared with a diet based entirely on bovine milk. The hypothesis tested was that adding a starch component (wheat flour) induces maturation of the mucosa as measured by higher digestive activity and improved integrity and immunity of the small intestines (SI). To test this hypothesis, piglets were removed from the sow at day 3 and fed either a pure milk replacer diet (MILK) or from day 11 a milk replacer diet with increasing levels of wheat (WHEAT). The WHEAT piglets had an increased enzyme activity of maltase and sucrase in the proximal part of the SI compared with the MILK group. There were no differences in gut morphology, histopathology and gene expression between the groups. In conclusion, the pigs given a milk replacer with added wheat displayed immunological and gut mucosal enzyme maturational changes, indicatory of adaptation towards a vegetable-based diet. This was not associated with any clinical complications, and future studies are needed to show whether this could improve responses in the subsequent weaning process.

Aim of the present study was to evaluate the effect of feeding dairy cows with extruded flaxseed (EF) on milk quality. After a 7-d adaptation period, 40 Holstein dairy cows in midlactation were divided in two experimental groups, based on parity, milk yield and composition, and days in milk. Animals were fed for 28 d a standard total mixed ration containing or not (control) 1.8 kg/cow/d of a supplement based on extruded flaxseed (EF). Milk yield was recorded daily and individual milk samples were collected weekly for analysis. Milk yield was not affected by treatment and averaged 26.2 kg/d throughout the study. Feeding EF reduced milk fat (3.95 vs. 4.24%; P=0.053) and tended to reduce milk protein (3.32 vs. 3.50%; P=0.104). The milk from cows fed EF contained more (P<0.01) stearic (12.0 vs. 7.8 mg/100 mg of fat), oleic (21.2 vs. 18.0 mg/100 mg of fat), ?-linolenic (0.85 vs. 0.41 mg/100 mg of fat) and vaccenic (1.43 vs. 0.62 mg/100 mg of fat) acids than control and also more c9,t11 CLA (0.91 vs. 0.59 mg/100 mg of fat). Conversely, compared with control, feeding EF reduced milk concentrations of palmitic acid (26.5 vs. 33.4 mg/100 mg of fat; P<0.01). The present results show that feeding EF to dairy cows is an efficient strategy to enrich milk in beneficial fatty acids such as vaccenic acid, CLA and omega-3 fatty acids. Nevertheless, the milk fat reducing effect of flaxseed as well as other sources of polyunsaturated fatty acids should be taken into account.

Medical authorities are increasingly recommending a reduction in the proportion of dietary energy derived from saturated fats (COMA). Milk processors are keen to identify new milk products for niche markets, and the production of 'healthier' milk may be required in the future. Dairy products are a major source of saturated fat in the diet and the work reported here examines the effect of feeding different sources of dietary oil on the fatty acid composition of bovine milk.In a 4 × 2 factorial experiment 96 Holstein cows were offered complete diets containing one of four oil sources, a calcium soap of palm fatty acid distillate(C), naked oats (O), pressure cooked whole soybeans (S) and partially oil extracted rapeseed (R), at two supplement to grass silage ratios (0.48:0.52 (low) or 0.70:0.30 (high)) in weeks 4 to 13 post calving.

Among family farmers, milk production is one of the main activities developed. The aim of this work was to evaluate the milk quality in the some properties and to monitor or manage the properties for observation of deficient points. The project was conducted on rural properties in the Bambuí / MG city and which works with bovine milk production, saves between 50 and 600 liters per day. The work started on March 2015 and ended on February 2016 and was developed through a partnership with Laticínio Total União Ltda. Three steps were performed, namely: data collection, milk quality analysis and work results obtained through meetings and lectures with producers and publication of booklet. The project's target farms was 12 rural properties with an average production of up to 600 liters of milk per day, without qualifying as small and medium producers, selected after the first phase. The milk quality analyzes were performed without 30 days interval for 4 months and the monitoring of the productive management performed throughout the project. It can be seen that the producers analyzed largely did not have the herd specialized in milk production and did not receive professional technical assistance.
